    Abstract:
    BACKGROUND: In a multinational clinical trial, valsartan was statistically not inferior to captopril in reducing mortality and cardiovascular morbidity after myocardial infarction (MI) in patients with signs of heart failure and/or left ventricular dysfunction. We conducted a prospective economic evaluation to compare within-trial resource use, costs, and quality of life in patients receiving valsartan, captopril, or both after MI. METHODS: We assigned country-specific unit costs to resource use data for 14703 patients and measured health-related quality of life in a subset of 4524 patients. We used the nonparametric bootstrap method to compare rates of resource use and costs, and a piecewise linear mixed-effects regression analysis to compare longitudinal measures of quality of life. RESULTS: There were no significant differences in rates of resource use between the valsartan and captopril groups. During an average follow-up of 2 years, total costs for patients receiving valsartan were significantly higher than for patients receiving captopril (USD 14103 vs USD 13038; 95% CI USD 369-USD 1875). The cost differential was caused primarily by the cost of the study medications (USD 1056 for valsartan vs USD 165 for captopril; 95% CI USD 867 to USD 912). Quality of life did not differ significantly between groups. CONCLUSIONS: For most patients at high risk after MI, the availability of generic captopril confers a cost advantage over valsartan because of lower medication costs. The difference will be smaller or nonexistent in settings where brand-name ACE inhibitors are prescribed.
