Scientists found that being overweight was independently associated with an increased risk for heart failure. Abdominal waist circumference or waist-to-hip ratio was associated with the greatest risk for heart failure among both men and women. Moderate or high levels of physical activity were associated with a reduced risk of heart failure. The protective effect of physical activity on heart failure was consistent in subjects at all levels of body mass index.

Previous studies have shown a link between low vitamin D status and heart disease. Now a new study shows that patients with high blood pressure who possess a gene variant that affects an enzyme critical to normal vitamin D activation are twice as likely as those without the variant to have congestive heart failure.
“This study is the first indication of a genetic link between vitamin D action and heart disease,” says Robert U. Simpson, professor of pharmacology at the University of Michigan Medical School and one of the authors of the study in the journal Pharmacogenomics.

Previous studies have found that omega-3 fish oil could reduce the incidence of heart failure in adults. A current study sought to determine whether those results could be duplicated.
