A recent research showed that 25 to 30 minutes workout is beneficial for heart failure patients. Research team led by Dr. Christopher O"Connor, director of the Duke Heart Centre found that exercising regularly can reduce hospitalization or death risk in heart failure patients.

For the study, 2,331 patients at 82 health centers in the United States, Canada and France were followed for more than two years. In the beginning of the study, researchers randomly divided the study subjects into two groups.

First group received normal care, including checkups and hypertension drugs while the second group got normal care, plus they were asked to start exercising on a treadmill or stationary bike for 30 minutes at least three times a week. Analysis of data showed that exercise group had a 15 percent lower risk of death from cardiovascular disease and hospitalization due to complications of heart failure.

Researchers said that the recent research will help in dispelling the old myth that heart failure patients can not workout as it will put stress on the heart.

O"Connor said: "The most important thing we found from this study is that exercise is safe for patients with heart failure, and when adjustments were made for specific baseline characteristics, it significantly improved clinical outcomes."
