ABSTRACT

Heart failure is a health care problem of enormous importance in the United States. As the

leading cause of elderly hospitalizations, congestive heart failure (CHF) claims over

40,000 deaths per year and contributes to an additional 250,000. More than five million

Americans are affected. An estimated half a million more individuals will be diagnosed

with CHF every year (1). Currently, the only definitive treatment modality for CHF is

cardiac transplantation. Though an effective option, the w2000 heart transplants performed annually have essentially no significant epidemiological impact (2). With

better treatment strategies continually evolving for coronary, valvular, and congenital

heart disease, improved patient survival ultimately will translate into a gradual progression

over time to cardiac failure in several of these patients. Myocardial function is at first

compromised but compensated. Once hearts can no longer compensate, however, patients

develop CHF. In pure economic terms, CHF costs the nation an estimated $10 to $50

billion annually. Clearly, more therapeutic options are needed.
