Don't put all your bets on fish oil
Wed, 24 Dec 2008 11:24:22 GMT
It is established that fish oil protects against deaths from heart problems, but doesn't count on fish oil to provide a clear benefit in heart rhythm problems (arrhythmias). More funding is urgently needed in this neglected area of nutrient research, say the authors of an accompanying editorial. Consuming oily fish at least two to four times a week is recommended for patients after a heart attack. But the evidence for the protective effect of fish oil supplements is based on one large trial from over 10 years ago. More recent trials have showed no beneficial effect of fish oil on patient outcomes........Survival after myocardial infarction
Wed, 24 Dec 2008 11:24:22 GMT
A paper published online by the journal Circulation on 8 December 2008 concluded that, while men and women have a similar in-hospital death rate following acute myocardial infarction, women with STEMI had an adjusted mortality rate almost twice as high as men (10.2% versus 5.5%). These differences were linked to a lower likelihood of reperfusion treatment in women. The paper was widely published in the press, with suggestions of disparity in care and outcome after AMI........New study 'pardons' the misunderstood egg
Wed, 24 Dec 2008 11:24:22 GMT
A study recently published online in the journal Risk Analysis(1) estimates that eating one egg per day is responsible for less than 1 percent of the risk of coronary heart disease (CHD) in healthy adults. Alternatively, lifestyle factors including poor diet, smoking, obesity and physical inactivity contribute 30 to 40 percent of heart disease risk, depending on gender. This study adds to more than thirty years of research showing that healthy adults can eat eggs without significantly affecting their risk of heart disease........Inflamed gums and heart disease
Wed, 24 Dec 2008 11:24:22 GMT
The next person who reminds you to floss might be your heart specialist instead of your dentist. Researchers have known for some time that a protein linked to inflammation (called CRP) is elevated in people at risk for heart disease. But where's the inflammation coming from? A new research study by Italian and U.K. researchers published online in The FASEB Journal shows that infected gums may be one place. Indeed, proper dental hygiene should reduce the risk of atherosclerosis, stroke and heart disease independently of other measures, such as managing cholesterol........Preventing a broken heart
Wed, 24 Dec 2008 11:24:22 GMT
A heart damaged by heart attack is commonly broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity. Now scientists have identified a key molecule involved in controlling excessive scar tissue formation in mice following a heart attack. When they stopped the scarring from occurring, the researchers observed that the animals' heart function greatly improved following the injury........Panic attacks linked to higher risk of heart attacks
Wed, 24 Dec 2008 11:24:22 GMT
People who have been diagnosed with panic attacks or panic disorder have a greater risk of subsequently developing heart disease or suffering a heart attack than the normal population, with higher rates occurring in younger people, as per research published in Europe's leading cardiology journal, the European Heart Journal [1] today (Thursday 11 December)........Women are more likely than men to die in hospital from severe heart attack
Wed, 24 Dec 2008 11:24:22 GMT
Men and women have about the same adjusted in-hospital death rate for heart attack - but women are more likely to die if hospitalized for a more severe type of heart attack, as per a report in Circulation: Journal of the American Heart Association. Among patients with ST elevation myocardial infarction (STEMI) in a recent study, the death rate was 10.2 for women in comparison to 5.5 for men. Scientists said the women were older and had higher overall baseline risk profiles than men. After adjustment for these and other differences, women with STEMI had a 12 percent higher relative risk for in-hospital death in comparison to men........A little wine boosts omega-3 in the body
Wed, 24 Dec 2008 11:24:22 GMT
Results from the European study IMMIDIET show that moderate wine intake is linked to higher levels of omega-3 fatty acids considered as protective against coronary heart disease. Moderate alcohol intake is linked to higher levels of omega-3 fatty acids in plasma and red blood cells. This is the major finding of the European study IMMIDIET that would be reported in the recent issue of the American Journal of Clinical Nutrition, an official publication of the American Society for Nutrition and is already available on line (www.ajcn.org ). The study suggests that wine does better than other alcoholic drinks. This effect could be ascribed to compounds other than alcohol itself, representing a key to understand the mechanism lying behind the heart protection observed in moderate wine drinkers........What makes the heart 'tick-tock'
Wed, 24 Dec 2008 11:24:22 GMTScientists have new evidence to show that the heart beats to its own drummer, as per a report in the recent issue of the journal Cell Metabolism, a Cell Press publication. They've uncovered some of the molecular circuitry within the cardiovascular system itself that controls the daily rise and fall of blood pressure and heart rate. The findings might also explain why usually used diabetes drugs come with cardiovascular benefits, as per the researchers........Up to 2 drinks per day not linked to heart problems in women
Wed, 24 Dec 2008 11:24:22 GMTWomen who have up to two alcoholic drinks per day do not appear to be at increased risk of atrial fibrillation (irregular heart beat), but drinking more than that amount is linked to a higher risk, as per a research studyin the December 3 issue of JAMA. Studies assessing the effects of regular alcohol consumption on the risk of atrial fibrillation have provided inconsistent results, with several studies finding significant associations between moderate to high amounts of alcohol intake and increased risks of atrial fibrillation among men, but not among women. However, these studies were not of adequate size to detect significant associations among women, as per background information in the article........Exposure to secondhand smoke reduced
Wed, 24 Dec 2008 11:24:22 GMT
As the correlation between second-hand smoke and coronary heart disease (CHD) became clearer and legislation was passed to reduce such passive smoking, exposures have been reduced. In an article reported in the January 2009 issue of the American Journal of Preventive Medicine, scientists from the University of California, San Francisco, Partners Healthcare, Boston and Columbia University have recalibrated the CHD Policy Model to better predict future trends in CHD........Some 'good cholesterol' isn't good enough
Wed, 24 Dec 2008 11:24:22 GMT
If you think your levels of "good cholesterol" are good enough, a new study reported in the December 2008 issue of The FASEB Journal suggests that you may want to think again. In the report, scientists from the University of Chicago challenge the conventional wisdom that simply having high levels of good cholesterol (HDL) and low levels of bad cholesterol (LDL) is necessary for good heath. Instead, they show that the good cholesterol has varying degrees of quality and that poor quality HDL is actually bad for you........Estrogen therapy could be dangerous for women
Wed, 24 Dec 2008 11:24:22 GMT
Hormone treatment could accentuate certain pre-existing heart disease risk factors and a heart health evaluation should become the norm when considering estrogen replacement, new research suggests. The research also showed that in women without existing atherosclerosis, hormone treatment use included some positive effects on lipids but also some negative effects correlation to heart health, said MaryFran Sowers, lead researcher and professor of epidemiology at the University of Michigan School of Public Health........Technology gives 3-D view of human coronary arteries
Wed, 24 Dec 2008 11:24:22 GMT
For the first time scientists are getting a detailed look at the interior of human coronary arteries, using an optical imaging technique developed at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH). In their report in the journal JACC: Cardiovascular Imaging, the research team describes how optical frequency-domain imaging (OFDI) gives three-dimensional, microscopic views of significant segments of patients' coronary arteries, visualizing areas of inflammation and plaque deposits........Mending broken hearts with tissue engineering
Wed, 24 Dec 2008 11:24:22 GMT
Broken hearts could one day be mended using a novel scaffold developed by MIT scientists and his colleagues. The idea is that living heart cells or stem cells seeded onto such a scaffold would develop into a patch of cardiac tissue that could be used to treat congenital heart defects, or aid the recovery of tissue damaged by a heart attack. The biodegradable scaffold would be gradually absorbed into the body, leaving behind new tissue........
