Abstract

Background The cost-effectiveness of β-blocker use in patients with chronic heart failure (CHF) has never been elucidated in a Japanese study. Methods and Results A Markov model for outpatients with CHF was constructed to simulate remaining life expectancy and expected medical costs for each patient. Each patient was assumed that they received either carvedilol in addition to conventional therapies (ie, digitalis, diuretics, and angiotensin-converting enzyme inhibitors) or conventional therapies alone. Analyses were conducted both for each patient's remaining lifetime and for a period of 5 years. Analyses were performed from the perspective of Japanese healthcare insurance. Analysis for treatment over the course of each patient's expected life span with carvedilol plus conventional therapies versus conventional therapies alone yielded expected medical costs of ¤3.5 million and ¤5.5 million respectively, and a life expectancy of 121 months and 88 months, respectively. The analysis of a 5-year period yielded ¤1.4 million and ¤2.8 million in expected medical costs and 49 and 45 months life expectancy, respectively, for carvedilol versus conventional therapy. Conclusions Carvedilol treatment for CHF patients is a highly cost-effective method of therapy in the Japanese medical environment. (Circ J 2004; 68: 35 - 40)
