Normally, in people with hypertrophic cardiomyopathy (HCM) – a condition that causes portions of the heart to get bigger without any obvious cause – the only way to see the structural changes in the heart is after a person has died. The condition is the number one cause of sudden cardiac death in young individuals. But a new scan technique could pick up signs that a person is at risk of suddenly dying from a hidden heart condition while they are still alive. Researchers from Oxford University developed the new technique, which uses microscopic imaging, to check for muscle fibre disarray. This is when abnormal fibre patterns occur in the heart, not allowing heartbeats to spread evenly across its muscle fibres, which can lead to potentially deadly heart rhythms. For the study – the findings of which are published in the Journal of the American College of Cardiology – the researchers scanned 50 patients with HCM and 30 healthy people. They were able to see disarray in the HCM patients’ muscle fibres – something that had never been witnessed before in living subjects. The scan technique, known as diffusion tensor magnetic resonance imaging, has, up until now, normally only been used on the brain, but scientific advances mean that it can now be used on the heart too. Dr Rina Ariga, study author and cardiologist at University of Oxford, said: “We're hopeful that this new scan will improve the way we identify high-risk patients, so that they can receive an implantable cardioverter defibrillator early to prevent sudden death.” Footballer Fabrice Muamba is one of the most famous people to be affected by HCM. He almost died after collapsing during a match in the UK. In fact, Muamba was technically dead for a staggering 78 minutes before regaining consciousness. At the time of the incident, Muamba was 23 years old and in his prime as an athlete.
Previous claims that one or two alcoholic drinks a day doesn’t do any harm and could actually be protective are now in significant jeopardy following the publication of a large genetic study in The Lancet. According to the UK and Chinese researchers who followed 500,000 Chinese people over a 10-year period, the findings of the study are the best evidence yet on the direct effects of alcohol. While the negative health implications of heavy drinking are understood, the impact of consuming small amounts of alcohol on a regular basis has remained unclear. The researchers, from the University of Oxford, Peking University and the Chinese Academy of Medical Sciences, found that: drinking one to two alcoholic drinks every day increased stroke risk by 10-15% drinking four alcoholic drinks every day increased stroke risk by 35% For the purposes of the study, one drink was defined as either: a small glass of wine a bottle of beer a single measure of spirits In other words, even light-to-moderate drinking can increase blood pressure and a person’s chances of having a stroke. Prof David Spiegelhalter, from the University of Cambridge, said drinking alcohol on a daily basis gives the “opposite effect of taking a statin” (drugs that are used to lower cholesterol levels). The bottom line, according to Prof Richard Peto, professor of medical statistics and epidemiology at the University of Oxford, is the “claims that wine and beer have magical protective effects is not borne out”.
Our daily diets are bigger killers than smoking and account for one in five deaths around the world. In other words, the food you eat could be sending you to an early grave. But which diets are the worst? Well, according to an influential study in The Lancet, salt – whether it be in bread, processed meals or soy sauce – shortens the most lives. The Global Burden of Disease Study used estimates of different countries’ eating habits to determine which diets were shortening the most lives. Here are the three most dangerous diets: Too much salt - three million deaths Too few whole grains - three million deaths Too little fruit - two million deaths Low levels of seeds, nuts, vegetables, fibre and omega-3 from seafood were the other major killers. Speaking to the BBC, Prof Christopher Murray, the director of the Institute for Health Metrics and Evaluation at the University of Washington, said: “We find that diet is one of the dominant drivers of health around the world, it's really quite profound.” Salt is such a big problem because it significantly increases a person’s blood pressure, which in turn increases their chances of heart attacks and strokes. Around 10 million out of the 11 million diet-related deaths were because of cardiovascular disease, highlighting why diets containing too much salt are such a problem.
A new cholesterol-lowering drug could offer hope for both people who are unable to take statins due to the side effects and for people who statins are ineffective. An international study suggests the drug, called bempedoic acid, helps lower cholesterol in people who continue to have high levels despite taking statins. It is thought that it can also be used for people who are unable to take statins because of the associated side-effects. Publishing their research in the New England Journal of Medicine, the researchers say they have asked UK and US drug regulators to consider approving the pill for widespread use. Bempedoic acid works by blocking an enzyme in the body that is used to produce cholesterol. For the study, over 1,000 people with cardiovascular disease or a genetic cholesterol condition were given bempedoic acid in addition to their usual cholesterol-lowering medication. About 700 other study participants were given a placebo. After just three months, the group taking bempedoic acid had 17% less bad cholesterol than the group receiving the dummy medication. Speaking about the findings of the research, Prof Kausik Ray, from Imperial College London, said: “Bempedoic acid could be another addition to the arsenal of cholesterol lowering treatments available to patients. “What we have is a new class of drug that could be given to patients who are already taking statins and could help them further reduce their cholesterol levels and thus potentially cut their risk of heart attacks and strokes.” Bad cholesterol remains one of the main risk factors for heart attacks and strokes across the world.
People who have a heart attack sometimes experience heart muscle damage. As a result, many live with heart failure and may require a heart transplant in the future. But what if there was a way for human hearts to heal themselves? Scientists say an exotic fish could perhaps hold clues to making such an occurrence a reality. The Mexican tetra fish, which lives in freshwater, can, quite amazingly, repair its own heart. Popular with aquarium owners because of its unique coloring, the tetra fish has many different species, most of which can heal their own hearts following damage. To understand how the tetra fish do this, a team of researchers from the University of Oxford in the UK travelled to the Pachón cave in Mexico to study a tetra subspecies, the “blind cave tetra”. This remarkable fish has not only lost its ability to see, but also its color. Moreover, it can no longer regenerate heart tissue. By studying the blind cave tetra alongside other species of tetra, the team of researchers was able to create genetic profiles for both, allowing them to better understand what gives the tetra its amazing heart regeneration abilities. The team, led by Dr. Mathilda Mommersteeg, an associate professor at the University of Oxford, identified three separate genomes relevant to the tetra’s self-healing. Further analysis revealed two genes, lrrc10 and caveolin, were far more active in the river tetras. “A real challenge until now was comparing heart damage and repair in fish with what we see in humans. But, by looking at river fish and cave fish side by side, we've been able to pick apart the genes responsible for heart regeneration,” said Dr. Mommersteeg. Going forward, the research team hopes it may be possible to develop a way for heart attack patients to repair their own heart tissue.
Strength training exercises benefit the heart more than aerobic activities, such as walking and cycling, new research suggests. The survey of more than 4,000 American adults found that static exercise, like lifting weights, is more effective at reducing the risk of heart disease than cardiovascular exercise. Specifically, while undertaking both static and dynamic exercise was associated with a 30% to 70% reduction of cardiovascular risk factors, the link was strongest for younger individuals who did static exercises. Nevertheless, any amount of exercise brings benefits and doing both static and dynamic types is still better than focussing on just one kind, the researchers from St. George's University in St. George's, Grenada said. Speaking about the findings of the research, Dr. Maia P. Smith, assistant professor at the Department of Public Health and Preventive Medicine at St. George's University, said: “Both strength training and aerobic activity appeared to be heart healthy, even in small amounts, at the population level.” Current American Heart Association (AHA) guidelines recommend that American adults should undertake at least 150 minutes of heart-pumping physical activity every week. The same guidelines also stipulate that said activity should be spread across the week and not completed in just one or two days. Are you doing enough physical activity each week? If not, you could be increasing your risk of cardiovascular disease. [Related reading: Why being overweight increases your risk of cancer]
Do you take supplements containing omega-3 fish oil in the belief they are helping to protect your heart? A new study suggests you could be wasting your money. Researchers from Cochrane analysed trials involving more than 100,000 people and discovered little proof that omega-3 supplements prevented heart disease. In fact, they say the chance of getting any benefits from such supplements is one in 1,000. However, despite this, the researchers still maintain that eating oily fish as part of a healthy diet is beneficial. Indeed, NHS guidelines state that people should try to eat two portions of fish each week, one of which, ideally, should be oily fish such as mackerel, salmon or fresh tuna. This is so they get enough “good” fats. Speaking about the findings of the research, Prof Tim Chico, a cardiologist from Sheffield University, said: “There was a period where people who had suffered a heart attack were prescribed these on the NHS. This stopped some years ago. “Such supplements come with a significant cost, so my advice to anyone buying them in the hope that they reduce the risk of heart disease, I'd advise them to spend their money on vegetables instead.” Dr Lee Hooper, from the University of East Anglia, said: “The most trustworthy studies consistently showed little or no effect of long-chain omega-3 fats on cardiovascular health.” Nevertheless, Dr Carrie Ruxton from the UK’s Health and Food Supplements Information Service said supplements containing omega-3 can still play an important role for people who don’t eat oily fish – especially as omega-3 also benefits the brain, eyes and immune function.
Doctors should take a person’s marital status into account when assessing their risk of heart attack and stroke, a major study has found. For the study, researchers at Keele University analysed numerous trials involving more than two million people. They found that individuals who were never married, divorced or widowed were 42% more likely to develop cardiovascular disease. They were also 42% more likely to die from heart disease and 55% more likely to die from a stroke. Risk factors such as age, sex, high cholesterol, high blood pressure, smoking, and diabetes are usually associated with cardiovascular disease. However, the findings of the new study suggest marital status should also be added to the list. Senior author, Mamas Mamas, Professor of Cardiology at Keele University, in England, said: “Our work suggests that marital status should be considered in patients with or at risk of developing cardiovascular disease, and should be used alongside more traditional cardiac risk factors to identify those patients that may be at higher risk for future cardiovascular events”. The researchers say the reason marriage could have a protective effect on cardiovascular disease is because of the additional emotional and social support that’s afforded by having a spouse. People with long-term partners are more likely to have symptoms spotted earlier and encouraged to seek medical advice as a result.
Have you ever encountered someone who calls themself ‘fat but fit’? It’s not uncommon to meet people who are clearly overweight, yet not perturbed by their situation because they consider themselves to be fit and healthy. However, a large study conducted in America has found that women who are overweight or obese but otherwise healthy are still at an increased risk of cardiovascular disease (CVD). For the study, researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke tracked the health of some 90,257 women in the US over a 30-year period. They found that women who were overweight or obese, but had none of the typical cardiovascular risk factors, such as high blood pressure, excess cholesterol and diabetes, were 20% and 39% more likely to develop cardiovascular disease than their normal weight and metabolically healthy peers. Speaking about the findings of the study, Prof Matthias Schulze, who led it, said: "Our large cohort study confirms that metabolically healthy obesity is not a harmless condition, and even women who remain free of metabolic diseases for decades face an increased risk of cardiovascular events.” The study also found women who were of normal weight, but metabolically unhealthy, were over two-times more likely to develop cardiovascular disease than their peers of the same weight who were metabolically healthy. Jeremy Pearson, associate medical director at the British Heart Foundation, added: "This large scale study confirms that obesity, even if unaccompanied by other warning signs, increases risk of cardiovascular disease in women."
People who regularly drink more than the UK’s recommended alcohol guidelines risk taking years off their lives, a major new report has found. According to the study of some 600,000 drinkers, having 10 to 15 alcoholic drinks every week could shorten a person's life by between one and two years. People who regularly consume more than 18 alcoholic drinks every week could lose four to five years of their lives. UK government guidelines, which were last updated in January 2016, recommend that both men and women should not drink more than 14 units of alcohol each week (equivalent to 6 pints of average strength beer). Previously, the guidelines advised 21 units for men and 14 units for women each week. The authors of the Lancet study say their findings support the UK government’s revised guidelines. Commenting on the study’s findings, Tim Chico, professor of cardiovascular medicine at the University of Sheffield, said: "This study makes clear that on balance there are no health benefits from drinking alcohol, which is usually the case when things sound too good to be true. "Although non-fatal heart attacks are less likely in people who drink, this benefit is swamped by the increased risk of other forms of heart disease including fatal heart attacks and stroke."
Do you know how much salt you consume on a daily basis? If you’re a fan of Chinese takeaway meals, it could be far more than you ever imagined, according to a campaign group. For their research, Action on Salt analysed more than 150 Chinese takeaway dishes from both restaurants and supermarkets. They found that most contained way too much salt – almost half the average person’s recommended daily amount of salt (6g) in some cases. When it comes to the saltiest meals, dishes like beef in black bean sauce topped the list. If a person adds a portion of egg fried rice, their salt intake could rise by as much as 5.3g in one meal. In fact, one portion of beef in black bean sauce and a side of vegetable noodles was found to contain as much salt as five Big Macs. While it’s vastly more difficult with Chinese takeaway food, Action on Salt recommends people check the nutritional information on supermarket bought food to see how much salt it contains. The campaign group says that many Chinese takeaway meals should carry health warnings because of the amount of salt they contain. Too much salt can lead to increased blood pressure, which can in turn increase a person’s risk of heart attack and stroke. Public Health England (PHE) has been encouraging the food industry to reduce the amount of salt found in food. Dr Alison Tedstone, chief nutritionist for PHE, said: "A loaf of bread has 40% less than it used to. "However, some products are still too high in salt and we know this can be reduced further. "We've been very clear with the food industry on the importance of meeting the 2017 salt targets. "We'll report on their progress this year and on any necessary advice to government on the next steps." So, the next time you reach to grab your favourite Chinese takeaway meal from the supermarket, just have a quick read of the nutritional information. What you discover might just make you choose something else instead.
Diabetes has long been split into two types: type 1 and type 2. But new research suggests it could actually be five different diseases and treatment could be tailored to tackle each form. Researchers in Sweden and Finland say the more complicated diabetes picture they’ve uncovered could lead to a new era of personalised medicine being ushered in. Affecting approximately one in 11 people around the world, diabetes doesn’t just play havoc with blood sugar levels, but also increases the risk of stroke, blindness, heart attack, kidney failure and limb amputation. Type 1 diabetes, which affects around 10% of sufferers in the UK, is a disease of the immune system that attacks the body’s insulin factories, leading to there being a shortage of the hormone to control blood sugar levels. Type 2 diabetes, on the other hand, is associated with poor lifestyle choices and obesity, which affect the way in which insulin works. For the study, the researchers analysed blood samples from 14,775 patients. They found that people could be separated into five distinct diabetes clusters. Talking to the BBC, Prof Leif Groop, one of the researchers, said: "This is extremely important, we're taking a real step towards precision medicine. "In the ideal scenario, this is applied at diagnosis and we target treatment better."
New research published in the Journal of the American Heart Association shows that waist-to-hip ratio is a better heart attack predictor than body mass index (BMI), with so-called “apple shape” women at greater risk than their male counterparts. According to the research from the George Institute for Global Health, waist-to-hip ratio is an 18% better heart attack predictor than BMI in women and 6% in men. However, the research also found that BMI was linked to heart disease risk in both sexes. For the research, the team from the George Institute in Oxford interviewed nearly 500,000 UK adults aged 40 to 69. They found women who had bigger waists relative to their hips are at more risk of heart attacks than men with similar body shapes. Speaking about the findings of the research, Ashleigh Doggett, senior cardiac nurse at the British Heart Foundation, said: "Considering the large amount of UK participants, this is a very interesting study which highlights that obesity remains a risk factor for heart attacks in both men and women. "Interestingly, it suggests that those of us who are 'apple' as opposed to 'pear' shape, especially women, may be at higher risk of a heart attack.” The researchers say their findings suggest the differences in the way men and women store fat may affect their risk of heart disease. While more research is needed, these findings do support the notion that being “apple shape” (having proportionally more fat around the abdomen) is more hazardous for your health than being “pear shape” (having proportionally more fat stored around the hips. The full findings of the research can be found in the Journal of the American Heart Association.
Researchers at an Oxford hospital have developed an Artificial Intelligence (AI) system that can accurately diagnose heart and lung scans. The new AI could lead to more people being diagnosed earlier and prevent patients being sent home when they are still at risk of having a heart attack. It’s though the system will save the NHS billions of pounds by enabling various diseases to be detected much earlier. The heart disease technology will be available to NHS hospitals for free this summer. Currently, cardiologists use a person’s heartbeat to tell if there is a problem. However, even the most experienced doctors get it wrong in one in five cases. This leads to a patient being sent home when they are still at risk of a heart attack or undergoing an unnecessary operation. The AI system can pick up details on the scans that doctors cannot see, resulting in a more accurate diagnosis. So far, the system has been tested in clinical trials and the results aren’t expected to appear in a peer-reviewed journal until later this year. However, one of the system’s developers has said the data shows it greatly outperformed his fellow specialists. The government's healthcare tsar, Sir John Bell, has indicated that AI could "save the NHS". "There is about £2.2bn spent on pathology services in the NHS. You may be able to reduce that by 50%. AI may be the thing that saves the NHS," he said.
Calcium is well-known for its role in promoting healthy bones, but a new study suggests it could also be beneficial for heart health too. Cardiac arrest, or heart attack, is one of the leading causes of death in the United States today. In fact, according to the American Heart Association (AHA), approximately 350,000 out-of-hospital sudden cardiac arrests (SCAs) occur in America every year. Furthermore, almost 90% of people who experience SCA die as a result. The primary cause of SCA is coronary heart disease. However, around 50% of women and 70% of men who die from SCA have no medical history of heart disease, suggesting other significant risk factors are at play. For the study, researchers from the Cedars-Sinai Heart Institute in Los Angeles, CA, analysed data from the Oregon Sudden Unexpected Death Study. They found that the risk of SCA was increased by 2.3-fold for people who had the lowest blood calcium levels (under 8.95 milligrams per deciliter). More importantly, this risk remained after confounding factors, including demographics, cardiovascular risk factors and medication use, were accounted for. Dr. Hon-Chi Lee, of the Department of Cardiovascular Medicine at the Mayo Clinic in Rochester, MN, said: “This is the first report to show that low serum calcium levels measured close in time to the index event are independently associated with an increased risk of SCA in the general population”.
A sudden chest pain often leads to people fearing the worst, which is why many, quite rightly, seek medical help right away. But two-thirds of the time, patients with chest pains will not actually have experienced a heart attack. Nevertheless, these patients still need to be assessed and given the all-clear before being sent home. Then there are the patients who have actually had a heart attack. While a heart trace, called an ECG, can quickly identify major heart attacks, it is not that good at highlighting smaller ones, which can also be life-threatening. At present, patients with a clear ECG and chest pain are then given a heart-attack blood test, called troponin. However, this needs to be repeated three hours later to check for signs of heart muscle damage. Now, a new instant blood test could change the way suspected heart attack patients are treated. The cMyC test can rule out or confirm a heart attack in less than 20 minutes, meaning well patients can be sent home quicker, while heart attack victims can get the treatment they need faster. Troponin and cMyC blood tests were carried out on nearly 2,000 people admitted to hospitals in Switzerland, Italy and Spain with acute chest pain. The cMyC test was found to be better at giving patients the all-clear within the first three hours of presenting with chest pain. According a team from King's College London, the cMyC test could be rolled out on the NHS within five years. Dr Tom Kaier, one of the lead researchers at St Thomas' Hospital, London, said: "Our research shows that the new test has the potential to reassure many thousands more patients with a single test, improving their experience and freeing up valuable hospital beds in A&E departments and wards across the country."

A study by Public Health England looking at the heart health of the nation has found that thousands of men face early death at the hands of a heart attack or stroke. In fact, according to the analysis of 1.2 million people, one in 10 British men has a heart age that’s a decade older than their actual age. Heart disease is the main cause of death among men and the second among women. Public Health England says that 7,400 people will die from heart disease or stroke this month alone. However, most of these deaths are preventable and Public Health England says that just a few small lifestyle changes can have a positive impact. One of the suggestions made was for over 50s to get their blood pressure regularly checked as high blood pressure can be an early sign of a potentially life-threatening condition. Public Health England’s head of cardiovascular disease, Jamie Waterall, urged people not to only start considering their heart health later in life. "Addressing our risk of heart disease and stroke should not be left until we are older", he said. How to improve your heart health: Give up smoking Get active Manage your weight Eat more fibre Eat five portions of fruit and vegetables per day Cut down on saturated fat Cut down on salt Drink less alcohol
A trial involving an anti-inflammatory drug could represent the biggest breakthrough in the treatment of heart attacks and strokes since statins were introduced to help lower cholesterol, its authors say. The study of 10,000 patients found that anti-inflammatory drug canakinumab reduced the risk of a patient who had already had a heart attack having another one in the future. The four-year trial saw patients receive high doses of statins as well as either canakinumab or a placebo. Those who received canakinumab were found to be 15% less likely to suffer from a cardiovascular event than their counterparts who received the placebo. Furthermore, cancer deaths were also halved in patients who received canakinumab. The results, which have been referred to as “exciting” by the British Heart Foundation, are thought to be down to the effect of the anti-inflammatory drug on unchecked inflammation within the heart’s arteries. Presenting their results at the European Society of Cardiology meeting, held in Barcelona, Spain, the research team from Brigham and Women's Hospital in Boston, led by the study's lead author Dr Paul Ridker, said the study represented "a milestone in a long journey". "For the first time, we've been able to definitively show that lowering inflammation independent of cholesterol reduces cardiovascular risk. "This has far-reaching implications." It is thought the trial could now lead to new types of treatment for heart attacks and strokes being developed.
People who are overweight or obese, despite appearing medically healthy, are still at increased risk of heart disease, experts warn. The notion that people can be ‘fat but fit’ is being challenged by research published in the European Heart Journal. According to the researchers from Imperial College London and the University of Cambridge, who studied health data relating to more than half a million people in 10 European countries, weight is still a heart disease risk factor even if someone has normal blood pressure, cholesterol and blood sugar levels. The study found that people who appeared healthy, with healthy blood pressure, cholesterol and blood sugar readings, were still 28% more likely to develop heart disease than individuals with health bodyweights. Even more at risk were people who were overweight or obese and had high blood pressure, cholesterol and blood sugar levels. Dr Ioanna Tzoulaki, from Imperial's School of Public Health, said: "I think there is no longer this concept of healthy obese. "If anything, our study shows that people with excess weight who might be classed as 'healthy' haven't yet developed an unhealthy metabolic profile. "That comes later in the timeline, then they have an event, such as a heart attack”. So the advice if you want to maintain a healthy heart is to watch your weight, even if you think you are fit.
A new type of heart scan that analyses the fat and inflammation around the heart’s arteries could more accurately predict who will have a heart attack. The new way of scanning, developed by a team at the University of Oxford, identifies potential ticking time bomb arteries, allowing high-risk patients to receive intensive treatment and reduce their risk of suffering a heart attack or stroke. Most of us know inflammation as the red, swollen, sore feeling you experience after cutting your skin. However, the same occurs in all the tissues in the body, including inside the heart. Inflammation on the inside of blood vessels is linked to the build-up of unstable plaques, which can break apart and block a coronary artery, starving the heart of oxygen – resulting in a heart attack. "The holy grail in cardiology is the ability to pick up inflammation in coronary arteries, it's been a challenge for the past 50 years," said Prof Charalambos Antoniades, one of the Oxford researchers. Prof Metin Avkiran, associate medical director at the British Heart Foundation, said: "Discovering which plaques are likely to rupture, so people can be treated before such a devastating event strikes, is a major objective of current research. "If the technique lives up to its promise in larger trials in patients, it could lead to more effective treatment to avoid a potentially fatal heart attack or stroke."
A vaccine that helps lower cholesterol will now be trialled on humans following successful studies in mice. Researchers from the Medical University of Vienna will now test the safety of their experimental treatment – which stops fatty deposits clogging the arteries – on 72 volunteers. If the trials are successful, the vaccine would offer an alternative for people who currently take pills on a daily basis to reduce their risk of angina, stroke and heart attack. Writing about their cholesterol-lowering vaccine in the European Heart Journal, Dr Guenther Staffler and colleagues from The Netherlands Organisation of Applied Scientific Research say it will take many more years of tests before it is known whether the treatment is safe and effective in humans. In studies of mice, the treatment cut low density lipoprotein (LDL) cholesterol (bad cholesterol) by as much as 50% over 12 months and appeared to stop the build-up of fatty deposits in the arteries. Regardless of whether the vaccine becomes available in the future, the researchers were keen to stress that it should not be seen as an excuse for people to avoid exercise and eat lots of high-fat food. Nevertheless, the treatment could be useful for individuals who have high cholesterol due to an inherited condition called familial hypercholesterolaemia.
While the association between a lack of exercise and an increased risk of chronic diseases, including type 2 diabetes and heart disease, is well-established, new research shows that just 14 days of physical inactivity can increase a person's risk such conditions. A study by the University of Liverpool found that young, healthy adults who switched from moderate-to-vigorous activity and then to near-sedentary behaviour for just 14 days experienced metabolic changes that could raise their risk of chronic disease and even premature death. Presenting their findings at the European Congress on Obesity 2017 in Portugal, Study leader Dr. Dan Cuthbertson and colleagues said that reducing physical activity for just 14 days led to a loss of skeletal muscle mass in the participants. However, the reduction of physical activity for 14 days also led to an increase in total body fat. Furthermore, said body fat was most likely to accumulate centrally, which the team notes is a significant risk factor for chronic disease. Current guidelines recommend that adults aged 18-64 undertake at least 150 minutes of moderate-intensity physical activity or 75 minutes of vigorous-intensity physical activity every week. However, the Centers for Disease Control and Prevention (CDC) says that fewer than 50% of adults meet these exercise recommendations. Are you doing enough exercise each week? Even just small lifestyle changes can make a big difference when it comes to your risk of chronic disease.
People with non-O blood could be at greater risk of stroke and heart attack, research suggests. Scientists say it's because A, B and AB blood contains higher levels of a blood-clotting protein. The research, which was presented at the 4th World Congress on Acute Heart Failure, analysed studies involving 1.3m people. It found that people 15 in 1,000 people with non-O blood suffered a heart attack, compared to 14 in 1,000 people with O blood. While these figures don't sound that startling at first, when applied to a whole population the numbers become more important. It is hoped that the findings will help doctors better identify who is at risk of developing heart disease. However, Dr Mike Knapton, associate medical director at the British Heart Foundation, said the findings would not have a large impact on the current advice issued by the charity. "Most of a person's risk estimation is determined by age, genetics (family history and ethnicity) and other modifiable risk factors including diet, weight, level of physical activity, smoking, blood pressure, cholesterol and diabetes. "People with a non-O blood group type - AO, BO and AB - need to take the same steps as anyone wanting to reduce their CVD risk." So regardless of your blood type, the advice remains the same: improve your diet, weight, level of physical activity and don't smoke. In addition, manage blood pressure, cholesterol and diabetes too. There's nothing you can do about your blood group, but you can make positive lifestyle changes to reduce your risk of heart attack and stroke.
Doctors say that an innovative new drug can cut bad cholesterol to unprecedented levels, reducing the risk of heart attacks and strokes for millions of people. Accounting for around 15 million deaths each year, heart attacks and strokes are the world's biggest killers. They are also the reason why people take drugs known as statins to reduce their levels of bad cholesterol, or LDL. Bad cholesterol causes blood vessels to fur up, which increases the chances of them blocking, leading to the heart or brain being starved of vital oxygen. The new drug, evolocumab, changes the way a person's liver works to help reduce bad cholesterol and is thought to be much more effective than statins. Evolocumab's potential was seen during a large international trial involving 27,000 patients who were already taking statins. "The end result was cholesterol levels came down and down and down and we've seen cholesterol levels lower than we have ever seen before in the practice of medicine," according to Prof Peter Sever, from Imperial College London. "They would have another 20% reduction in risk and that is a big effect. It is probably the most important trial result of a cholesterol lowering drug in over 20 years," he added. One heart attack or stroke was prevented for every 74 patients taking evolocumab in the two-year trial. The British Heart Foundation's medical director, Prof Sir Nilesh Samani, said: "This trial is a significant advance" in fighting one of the biggest killers in the world.
Millions of people all over the world struggle with their waistlines. A constant battle that sees them diet, lose weight and then put it all back on again - sometimes more than they had originally. It's a pattern known as "yo-yo dieting", and a new study suggests that it can be hard on the hearts of older women. According to study leader Dr. Somwail Rasla, who's an internal medicine resident at the Memorial Hospital of Rhode Island in Pawtucket (US), "Women with a normal [weight] who experience yo-yo dieting throughout their adult life are at increased risk of sudden cardiac death and coronary heart disease death". Last week's American Heart Association conference in New Orleans heard that older women who are not necessarily overweight, but continue to strive for that so-called "perfect figure", increase their risk of sudden cardiac death by as much as 66%, which is 3.5 times higher than women who maintain a stable weight. It's long been known that being overweight as you reach middle age is linked with a higher risk of mortality due to heart disease, but the risks associated with yo-yo dieting have had much less research. For the study led by Rasla, the weight histories of 158,000 older, postmenopausal women were analysed. The women who were deemed to be yo-yo dieters - characterised as a cycle of gaining and losing 10 pounds or more - were also found to have a greater risk of coronary heart disease. Until further research is conducted, the message for now from Rasla is that "maintaining a stable body weight is best for overall health."
A new study has found the typical "social business diet", which consists heavily of red meats, sweet drinks, processed snacks and alcohol, has a detrimental effect on a person's heart. Unfortunately, it's a sign of the times that many individuals do not have, or at least don't think they have, enough time to sit down and eat a healthy meal. Instead, many people rely on grab-and-go food items that can be eaten on the road. However, according to a team of researchers from the Icahn School of Medicine at Mount Sinai in New York City, eating habits such as these up the risks of atherosclerosis - a slow, but steady clogging of one's arteries. In fact, eating out, snacking on the go, and excessive alcohol consumption is more unhealthy than the so-called Western diet. "This business diet is really very bad," said Dr. Valentin Fuster, a cardiology professor from Icahn. "It hits the arteries hard, and strongly contributes to cardiovascular disease risk, the world's number one killer," he added. The American Heart Association says that cardiovascular disease accounts for more than 17 million deaths across the world each year. Atherosclerosis occurs when plaque builds up in a person's arteries, and can raise their risk of blood clots, heart attacks, heart disease and stroke. If people want to lower their risk of cardiovascular problems in the future, they should minimise their consumption of red meat, sweets and alocohol, and increase their intake of vegetables, fruits, low-fat dairy products, whole grains, fish and nuts.
A new study has found that obese patients who undergo bariatric weight loss surgery have a greater chance of survival than those who do not. According to the research from a team at the University of Gothenburg in Sweden, weight loss surgery decreased the chance of death by as much as 57% compared with not having it. Being obese or overweight has been linked to many diseases, including heart attack, stroke and several different cancers, and can increases a person's risk of death as a result. Of the 48,693 patients (aged 18 to 74 years old), 22,581 underwent bariatric surgery - a gastric band was fitted in 92.8% of cases. The remaining 26,112 obese patients had no surgery at all. The researchers, led by Dr Christina Persson, found that the mortality rate in the group that did not have surgery was 4.21% compared to just 1.1% for the surgical group. That's equivalent to 7.7 deaths per 1,000 people each year versus just 2.1. Cardiovascular disease was the most common cause of death in the non-surgical group, followed by cancer, while external causes of mortality, such as suicide and accidents, were found to be the most common causes of death in the surgical group. "The study indicates that the overall all-cause mortality is considerably lower among obese individuals who undergo bariatric surgery compared to non-surgical obese individuals, and the differences lies mainly in cardiovascular disease and cancer," said Dr Persson. The findings of the study were presented at the recent European Obesity Summit in Sweden. To find out how France Surgery can help you undergo bariatric weight loss surgery, contact us today.
It's been widely accepted for some time that a high-salt diet may increase a person's risk of having a stroke or a heart attack. But now a new study has found that a low-salt diet may also be just as dangerous. Published in The Lancet, the findings of the study suggest that people who have a low salt or sodium intake may be increasing their risk of cardiovascular disease, compared to those who have an average intake. In fact, the study, which was conducted by researchers at McMaster University and Hamilton Health Sciences, says that the only people who should look to reduce their salt consumption are those with high blood pressure. Furthermore, the researchers say that current salt consumption guidelines may be too low, and should be reviewed going forward. At present, it is recommended that Americans consume no more than 2,300mg of salt each day, which is about 1 teaspoon. However, around 90% of US adults exceed this recommendation on a regular basis, according to a report from the Centers for Disease Control and Prevention (CDC) released earlier this year. On the other hand, the World Health Organisation (WHO) recommends people eat between 5 and 6g of salt each day. The lead author of the study, Andrew Mente, said: "While our data highlights the importance of reducing high salt intake in people with hypertension, it does not support reducing salt intake to low levels." Despite the study focusing on 130,000 people across 49 countries, its methods have been criticised by experts, while others have questioned the study's findings. The bottom line? Salt should be consumed in moderation, and people with high blood pressure should seek specific medical advice to find out what is best for them.
Surgeons in the UK have said that the number of weight loss operations performed on the NHS each year needs to rise dramatically, so that people become healthier and the health service itself saves money. Writing recently in the British Medical Journal, the bariatric surgeons said that less than 1% of people who could benefit from weight loss surgery are getting treatment, and the numbers are actually dropping, despite rising rates of obesity and diabetes. [Related article: Mediterranean diet reduces heart attacks and strokes] The surgeons also highlighted that the UK is lagging behind its European counterparts when it comes to weight loss surgery, and that there are 2.6 million people in the country who stand to benefit from surgery. According to the surgeons, people who have stomach shrinking operations lose 25-35% of their body weight, on average, in just a year. In comparison, the average loss through diets and weight loss drugs is just 7% a year. It's thought that a quarter of adults in the UK are now classified as obese - the second highest rate in Europe behind Hungary - and this reality is putting a huge strain on NHS resources and funds. The National Institute for Health and Care Excellence (Nice) has previously indicated that surgery should be considered for severely obese people who have unsuccessfully tried all other means to lose weight.

Last year, we told you about the benefits to your gut of following a Mediterranean diet. Now, research published in the European Heart Journal says that a Mediterranean diet is better for people with heart disease than avoiding what's considered unhealthy in the so-called 'Western diet'. The new research shows that a Mediterranean diet, which includes large amounts of fruit, vegetables, fish and unrefined foods, can decrease the risk of stroke and heart attack in people who already have heart disease. Likewise, the study found that avoiding the unhealthy aspects of a Western diet, such as sweets, sugary drinks and deep-fried foods, also reduced a person's risk of cardiac issues. For the study, researchers from Auckland City Hospital at the University of Auckland in New Zealand analysed the dietary data of some 15,482 people with stable coronary artery disease across 39 countries globally. They found that fewer heart attacks and strokes were witnessed among those people who eat Mediterranean foods. In fact, for every 100 people eating Mediterranean foods, there were three fewer strokes, heart attacks or deaths than seen among the 100 people who consumed the least amount of healthy foods. Lead researcher Prof. Ralph Stewart said: "The research suggests we should place more emphasis on encouraging people with heart disease to eat more healthy foods, and perhaps focus less on avoiding unhealthy foods."
A new study has revealed that heart attack victims in the United States are becoming younger and fatter. Over the past two decades alone, the average age of people suffering the deadliest heart attacks has fallen from 64 to 60, and obesity has been implicated in 40% of the most severe, according to researchers at Cleveland Clinic, Ohio. In addition, heart attack sufferers nowadays are more likely to be smokers and people with high blood pressure, diabetes and chronic obstructive pulmonary disease (COPD), compared to 20 years ago. It's a reality that is raising alarm bells. "Lifestyle changes to reduce weight, eat right, exercise and quit smoking are critical for prevention of heart attack," said senior researcher Dr. Samir Kapadia, an an interventional cardiologist in the Cleveland Clinic Department of Cardiovascular Medicine at Cleveland Clinic. Dr. Kapadia added that the responsibility for making these lifestyle changes should be shared between the patient and their medical doctor, and the issue discussed at routine checkups. The study focused on analysing heart disease risk factors among more than 3,900 patients; all of whom had been treated for an ST-elevation myocardial infarction (STEMI). One of the most severe types of heart attack, STEMIs often result in disability or death and occur when the heart's main artery is completely blocked by plaque. The results of the study are scheduled to be presented on April 4 at the American College of Cardiology's annual meeting in Chicago.
Acid indigestion can strike at any time and can be seriously uncomfortable when it does. Luckily, though, there are a range of over-the-counter medicines available, which quickly relieve the symptoms of acid indigestion, also known as heartburn. But now a new study, recently published in the journal PLOS ONE, has revealed that your chosen heartburn remedy could actually be putting your heart at risk; even if you’ve never had heart problems before. Researchers found that people who took proton pump inhibitors (PPIs) to tackle acid indigestion were at 16% greater risk of a heart attack than those who didn’t. Not all acid indigestion medications are classed as PPIs and the other main type – H2 blockers – were found not to pose the same risk of heart attacks by the researchers. “These drugs [PPIs] were only approved for short-term use, but as over-the-counter medications, the duration of use is not being monitored adequately,” said John Cooke, MD, PhD, study author and chair of the department of cardiovascular sciences at Houston Methodist Research Institute. “Furthermore, these drugs should only be used when safer agent, such as H2 antagonists like Tagamet or Zantac, are not effective in treating symptoms.” He suggests that PPIs should only be used under the directions of a doctor. So the next time you get acid indigestion, think twice before grabbing PPI medication… Photo credit: CNN
According to a biennial report into healthcare across Europe, France remains in very good shape. It has the lowest stroke and heart attack death rates on the continent and was one of the few countries to increase healthcare spending in 2014. The report, which also analysed non-EU countries, such as Switzerland, Norway and Iceland, outlined many areas where France is leading the field. Average life expectancy in France is an impressive 82.1 years and it also boasts just 86 heart attack deaths per 100,000 people. Compare this to the 184 that occur in the UK and you can see how impressive France’s figures are. France is also a big spender when it comes to hospital expenses – 38% of the total healthcare budget (4.4% of GDP). This comes at a time when most European countries are trying to cut their healthcare spending. France increased its own by 0.8%. Finally, France is a big spender on antibiotics and other pharmaceuticals – 469 euros per head compared to an average of 350 euros across the rest of Europe. The Health at a Glance – Europe 2014 report further underlines the great healthcare system we have here in France.

The benefits of weight loss surgery have been known for quite some time now and it’s a procedure that has helped many people regain their confidence and start living normal lives again. However, new research has shown that people with metabolic syndrome are more prone to lower urinary tract problems and that weight loss surgery can be used to significantly improve lower urinary tract symptoms. The first of the two studies was conducted by Dr. François Desgrandchamps and his colleagues at the Saint-Louis Hospital in Paris, France. They studied 4,666 men over a period of 12 days in 2009 and found that there was a strong link between metabolic syndrome and lower urinary tract symptoms. Furthermore, lower urinary tract symptoms were more severe in men with metabolic syndrome. The second study, conducted by a team at Wakefield Hospital in New Zealand, analysed 72 weight loss surgery patients before and after their procedures. They found that after just 6 weeks patients with lower urinary tract symptoms showed significant improvement. Metabolic syndrome is thought to affect around 34% of adults in the U.S. and puts them at greater risk of strokes, heart attacks, type 2 diabetes and cardiovascular disease. It is diagnosed when an individual displays three or more metabolic risk factors, which include high cholesterol, high blood pressure, abdominal obesity and high blood glucose levels.
