cost-effectiveness evaluation of aspirin in primary prevention of myocardial infarction amongst males with average cardiovascular risk in iran

aspirin is one of the certified medicines commonly used for the secondary prevention of myocardial infarction (mi). aspirin side effects and gastrointestinal bleeding, in particular, have arisen debates on its use for the primary prevention of mi. the present research evaluates the cost-effectiveness of the use of aspirin in the primary prevention of mi among iranian men with average cardiovascular disease (cvd) risk, using markov modeling technique. the incremental cost-effectiveness ratios (icers) estimated to be 864 usa dollars (usd) per quality-adjusted life years (qaly) gained and 782 usd per life years gained (lyg) for each patient in the base-case scenario (public tariffs and no discounting). this research proves cost-effectiveness of the use of aspirin in the primary prevention of mi in targeted population, since the assessed icers are quite under the recommended threshold by who which is one gross domestic product (gdp) per capita ($5315.1 for iran in 2015).
