A year of exercise training helped to preserve or increase the youthful elasticity of the heart muscle among people showing early signs of heart failure, a small study shows.
The new research, published in the American Heart Association journal Circulation, bolsters the idea that “exercise is medicine,” an important shift in approach, the researchers wrote.
The study focused on a condition called heart failure with preserved ejection fraction, which affects about half of the 6 million people in the United States with heart failure. Characterized by increasing stiffness of the heart muscle and high pressures inside the heart during exercise, the condition is largely untreatable once established and causes fatigue, excess fluid in the lungs and legs, and shortness of breath.
