Congestive Heart Failure (CHF) accounts for about a quarter of a million deaths a year, and currently its prevalence among the U.S. population is 4.8 million (1). CHF occurs when the heart cannot meet the demands of the body. The symptoms are breathlessness and fatigue due to a build up of fluid in and around the lungs. The failing heart inflates like a water balloon and, over time, gets stretched out to the point where it becomes a flimsy sac saturated with blood. If this sac is agitated with vigorous exercise it can, in some cases, fail.
