Exercise Improves Heart Rate Recovery in Heart Failure Patients

[Admin]

NEW YORK (Reuters Health) Jun 29 - Exercise training hastens heart rate recovery after cycle ergometry testing in patients with heart failure, according to a report in the June issue of the American Heart Journal.

Heart rate recovery reflects vagal tone that is associated with survival, the authors explain, but little is known about the effects of exercise training on heart rate recovery in patients with heart failure.

Dr. Jonathan Myers from the Veterans Affairs Palo Alto Health Care System, California and associates assigned 24 patients with heart failure to a 2-month, high-intensity residential exercise training program or to usual care.

After training, patients showed a 29% increase in maximal oxygen uptake during exercise testing along with increases in maximal minute ventilation, carbon dioxide production, exercise time, and watts achieved, the authors report. The control group showed no significant changes from baseline to the end of the study.

Heart rate recovery was significantly faster for minutes 2 to 6 in the intervention group after training, the report indicates, and the faster recovery was more pronounced as the recovery period progressed.

In contrast, heart rate recovery did not change significantly in the control group.

"The present results therefore suggest that training may have a considerable effect on outcomes in patients with heart failure via altered vagal modulation," the investigators say.

"Heart rate recovery, as a simple marker of autonomic function, is an easily acquired response that may be useful in identifying high-risk patients and for evaluating patient outcomes in cardiac rehabilitation," the authors conclude.

Not only is exercise good for your physical health, it also improve your mental state as studies have shown.

You are right jennart. I recently read the same thing as you are saying. I think there is no exercise that will have negative effect. Of course, we have to know out limits as well.

If you have 't time for exercise then do the walking in morning or after dinner. It is really very much beneficial. Walking is best medicine for keeping fit and healthy, I am doing walking as well as cycling for one hour and I loss my 3 and half weight in a week.
