[BDSP. Notice produite par INIST yR0x9EeR. Diffusion soumise à autorisation]. Context bêta-Blockers are underused in patients who have myocardial infarction (MI), despite the proven efficacy of these agents. New evidence indicates that bêta-blockers can have benefit in patients with conditions that have been considered relative contraindications. Understanding the consequences of underuse of bêta-blockers is important because of the implications for current policy debates over quality-of-care measures and Medicare prescription drug coverage. Objective To examine the potential health and economic impact of increased use of bêta-blockers in patients who have had Ml. Design and Setting We used the Coronary Heart Disease (CHD) Policy Model, a computer-simulation Markov model of CHD in the US population, to estimate the epidemiological impact and cost-effectiveness of increased bêta-blocker use from current to target levels among survivors of Ml aged 35 to 84 years. Simulations included 1 cohort of Ml survivors in 2000 followed up for 20 years and 20 successive annual cohorts of all first-MI survivors in 2000-2020. Mortality and morbidity from CHD were derived from published meta-analyses and recent studies. This analysis used a societal perspective. Main Outcome Measures Prevented MIs, CHD mortality, life-years gained, and cost per quality-adjusted life-year (QALY) gained in 2000-2020. (...)
