Cold weather leads to higher blood pressure

Tue, 13 Jan 2009 05:53:53 GMT

(image) Outdoor temperature and blood pressure appear to be correlated in the elderly, with higher rates of high blood pressure in cooler months, as per a report in the January 12 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Seasonal variations in blood pressure have been recognized among the general population for 40 years, as per background information in the article. However, few prior studies have looked specifically at elderly adults. "Elderly persons appears to be especially susceptible to temperature-related variations in blood pressure," the authors write. "The baroreflex, which is one of the mechanisms of blood pressure regulation, is modified in elderly subjects, and it has been hypothesized that disorders of baroreflex control and enhanced vasoreactivity [sensitivity of blood vessels] could contribute to the aging-associated increase in cardiovascular morbidity [illness]"........

Younger Adults Could Be At Risk For Heart Disease

Tue, 13 Jan 2009 05:53:53 GMT

(image) Even younger adults who have few short-term risk factors for heart disease may have a higher risk of developing heart disease over their lifetimes, as per new findings by a UT Southwestern Medical Center researcher. The findings, based on clinical studies and appearing in the Jan. 26 issue of the journal Circulation: Journal of the American Heart Association, suggest that traditional methods of identifying heart disease risk might not adequately identify patients who actually have a higher lifetime risk........

organic substance may help heal broken hearts

Tue, 13 Jan 2009 05:53:53 GMT

(image) Imagine new therapys for heart disease or muscle loss that direct the body to repair damaged tissue rather than helping it cope with a weakened condition. That's not hard to do thanks to Canadian researchers, who for the first time, have developed an organic substance that attracts and supports cells necessary for tissue repair and can be directly injected into problem areas. This development, published online in The FASEB Journal ( is a major step toward therapys that allow people to more fully recover from injury and disease rather than having to live with chronic health problems. It may even help reduce the need for organ transplantation by allowing physicians to save organs that would have been previously damaged beyond repair........

Fighting cholesterol with synthetic HDL

Tue, 13 Jan 2009 05:53:53 GMT

(image) Buttery Christmas cookies, eggnog, juicy beef roast, rich gravy and creamy New York-style cheesecake. Happy holiday food unfortunately can send blood cholesterol levels sky high. Northwestern University researchers now offer a promising new weapon -- synthetic high-density lipoprotein (HDL), the "good" cholesterol -- that could help fight chronically high cholesterol levels and the deadly heart disease that often results........

New risk assessment tools need to predict Coronary Heart Disease

Tue, 13 Jan 2009 05:53:53 GMT

(image) The Framingham and National Cholesterol Education Program tools, NCEP, do not accurately predict coronary heart disease, as per a research studyperformed at the Yale University School of Medicine in New Haven, CT. The study included 1,653 patients who had no history of coronary heart disease; eventhough 738 patients were taking statins (cholesterol lowering drugs like Lipitor) because of increased risk of developing coronary heart disease. All 1,653 patients underwent a coronary CT angiogram and doctors compared their risk of coronary heart disease, determined by the Framingham and NCEP risk assessment tools, to the amount of plaque actually found in their arteries as a result of the scan. Results showed that 21% of the patients who were thought to need statin drugs before the scan (because of the Framingham and NCEP assessment tools) did not require them; "26% of the patients who were already taking statins (because of the risk factor assessment tools) had no detectable plaque at all," said Kevin M. Johnson, MD, main author of the study........

Secrets of smoking addition

Tue, 13 Jan 2009 05:53:53 GMT

(image) Just seeing someone smoke can trigger smokers to abandon their nascent efforts to kick the habit, as per new research conducted at Duke University Medical Center. Brain scans taken during normal smoking activity and 24 hours after quitting show there is a marked increase in a particular kind of brain activity when quitters see photographs of people smoking........

Don't put all your bets on fish oil

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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

Tue, 13 Jan 2009 05:53:53 GMT

(image) 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 ( ). 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'

Tue, 13 Jan 2009 05:53:53 GMT

(image) Scientists 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........
