Exercise Training in Heart Failure: Changes in Cardiac Structure and Function

This is a research study being conducted to better understand the impact of exercise training on changes on the structure and function of the heart. Exercise training in patients with heart failure has been shown to be beneficial at decreasing symptoms of heart failure and improving overall functional capacity or capacity to exercise. However the mechanisms responsible for this are still unclear. This study will look specifically at how exercise creates changes within the hearts filling ability, the hearts pumping strength as well as the hearts ability to rebuild.
