Abdominal Fat Most Strongly Linked to Hypertension Risk

The association between obesity and the development of hypertension appears to be driven specifically by visceral adiposity, according to research published in the Sept. 9 issue of the Journal of the American College of Cardiology. Alvin Chandra, M.D., of the University of Texas Southwestern Medical Center in Dallas, and colleagues followed 903 normotensive participants of the Dallas Heart Study (median age, 40 years; 57 percent women; 60 percent nonwhite; median body mass index, 27.5 kg/m²) for a median of seven years to monitor the development of hypertension. Imaging studies were used to assess adiposity, including visceral adiposity. Source: Physician's Briefing Read More

More Leisure Physical Activity Tied to Lower Heart Failure Risk

Higher leisure time physical activity is associated with a lower risk of developing heart failure, according to a study published online Sept. 2 in Circulation: Heart Failure. Kasper Andersen, M.D., Ph.D., from Uppsala University Hospital in Sweden, and colleagues evaluated responses to a questionnaire of lifestyle factors and medical history for 39,805 individuals without baseline heart failure in 1997. They assessed the total and direct effects of self-reported total and leisure-time physical activity on the risk of heart failure of any cause and heart failure of non-ischemic origin. Read More

New methods enhance the quality of myocardial perfusion imaging

New methods that enhance the quality of myocardial perfusion imaging were developed in a recent study completed at the University of Eastern Finland. In her PhD study, Tuija Kangasmaa, Lic. Phil., invented a method which makes it possible to reduce the imaging time by up to 50%, making the scan session easier for the patient. Furthermore, the study also created two additional methods which correct errors resulting from patient movement during the scan. The methods were validated and they have already been taken into use in hospitals all over the world. Source: MedicalNewsToday Read More

New drug '20% more effective than ACE inhibitors' for treating heart failure

For treating patients with chronic heart failure, ACE inhibitors are usually the first port of call. But a new study claims an experimental drug called LCZ696 performs around 20% better than ACE inhibitors when it comes to reducing rates of hospitalizations and deaths due to chronic heart failure.

Physical activity cuts risk of irregular heartbeat in older women

By now, most of us are aware of the plethora of health benefits linked to exercise. But for older women, another advantage been added to the list; researchers publishing in the Journal of the American Heart Association say increasing the amount or intensity of exercise can decrease risks of developing arrhythmia - a life-threatening irregular heartbeat.

Eating fresh fruit every day 'could reduce risk of CVD by up to 40%'

Cardiovascular disease is the leading cause of death in the US. Each year, 600,000 people die from heart disease and 130,000 die from stroke. But a new study finds that the risk of developing cardiovascular disease could be reduced by up to 40%, simply by eating fresh fruit every day. Source: MedicalNewsToday Read More

Race and ethnicity important when evaluating risk of fat around the heart

A man's likelihood of accumulating fat around his heart - an important indicator of heart disease risk - may be better determined if doctors consider his race and ethnicity, as well as where on his body he's building up excess fat, reveals an international evaluation led by the University of Pittsburgh Graduate School of Public Health.

A new way to look at diabetes and heart risk

People with diabetes who appear otherwise healthy may have a six-fold higher risk of developing heart failure regardless of their cholesterol levels, new Johns Hopkins Bloomberg School of Public Health research suggests. Source: MedicalXpress Read More

Coronary arteries hold heart-regenerating cells

Source: ScienceDaily Endothelial cells residing in the coronary arteries can function as cardiac stem cells to produce new heart muscle tissue, investigators have discovered. The heart has long been considered to be an organ without regenerative potential, said one expert. Recent findings, however, have demonstrated that new heart muscle cells are generated at a low rate, suggesting the presence of cardiac stem cells. The source of these cells was unknown. Read More

Device implanted for tricuspid valve replacement: First in United States

America's first transcather tricuspid heart valve replacement has been performed, providing an alternative to open heart surgery, clinical scientists report. Percutaneous interventions use hollow tubes called catheters to reach chambers of the heart rather than opening a patient's chest, and are increasingly used to fix heart valves.
