An overview of intermittent inotropic therapy for severe congestive heart failure.
Congestive heart failure (CHF) is a major problem in the field of medicine in the U.S. Over 4 million people in the U.S. have CHF with 400,000 new cases per year. This diagnosis creates 6 million hospital days with a Medicare cost of billions of dollars. There are limited options for patients >65 years of age who have resistant heart failure on maximum medical therapy. There is considerable debate surrounding intermittent inotropic therapy. This paper is a review of the literature regarding this form of therapy; 20 studies are described. All but one of these studies disclose beneficial effects. The major criticism of these studies is that they are small and not randomized or placebo controlled. Larger well controlled studies are needed to determine the effect and safety of this treatment. Researchers must develop and evaluate all forms of therapy fairly to help decrease hospitalizations, decrease mortality, and improve quality of life.
