Heart failure patients may benefit from leg exercises

Cardiovascular patients looking for a cheaper way to help avoid a heart attack can buy Canadian Lipitor to control cholesterol. Such health events could eventually lead to heart failure and other lifelong complications, one of which may be impairment of the leg muscles, according to researchers from the University of Leeds.
A team of scientists examined the activities of the heart, lungs and leg muscles of chronic heart failure patients after they performed a moderate exercise warm-up. With the help of a near-infrared laser, the scientists were able to measure oxygen use and energy production in the legs. While these two activities increased for all individuals, patients with the most severe cases of heart failure had impaired functions in their legs, as published in the Journal of Applied Physiology.
"Many chronic heart failure patients complain of leg fatigue during exercise and this can prevent them from being active," said author Harry Rossiter. "Our study shows that by warming up properly, patients can improve the oxygenation and performance of their leg muscles, which is beneficial in promoting exercise tolerance."
Further research is needed to investigate whether training the skeletal muscles has any benefits for patients with chronic heart failure, and if the disease has any other negative effects on the legs.
