Aerobic Training and Cardiopulmonary Responses In Heart Failure

The Impact of Aerobic Exercise Training on Cardiopulmonary Exercise Capacity in Patients With Heart Failure

The goal of this observational study is to learn about the short-term effects of aerobic exercise in heart failure patients who were given exercise prescription with cardiopulmonary exercise stres test acocording to aerobic capacity . The main question it aims to answer is:

Does aerobic exercise increase aerobic capacity and quality of life Participants already taking aerobic capacity as part of their regular medical care for Heart failure will asses with cardiopulmonary exercise test and clinical questionaries about quality of life and depression-anxiety level before and after aerobic exercise treatment .
