A new study suggests fish oil (omega-3 fatty acid) supplements may help heart failure patients.

Comparing two drugs used to treat heart failure -- candesartan and losartan -- researchers found that candesartan was linked to a lower risk of death at 1-year and 5-year follow-ups.

Women with mild heart failure who received a cardiac resynchronization device combined with defibrillator (CRT-D) showed a 70 percent reduction in heart failure and a 72 percent reduction in overall mortality.

S3, an abnormal sound strongly linked to cardiac disease and heart failure, can be notoriously difficult for physicians to hear. The low-pitched, low-frequency sound isn't readily picked up by stethoscope alone.

A recent study from the Dana Farber Cancer Institute has found breast cancer drug bevacizumab (Avastin, Genentech) appears to increase risk of congestive heart failure.
