Previous studies looking at the benefits of exercise in HF patients have been inconclusive and have lacked safety data.
This latest study, called ACTION, involved 1,159 patients who were randomly assigned to exercise training and 1,172 patients who did not exercise but had moderate physical activity.
At the end of the 2.5 year study, the researchers found that exercise training reduced the risk of hospitalisation for cardiovascular problems and HF by 15%.
Exercise reduced total mortality by 11% compared with not exercising.
