Adherence with statin therapy in secondary prevention of coronary heart disease in veterans administration male population

This retrospective cohort study enrolled 8,768 male Veterans Administration patients with coronary heart disease who were prescribed statins from July 1, 1999, to June 30, 2000. After 18 months of follow-up, 71% of the patients had been dispensed ≥80% of the medication. Our populationʹs persistence in using statins was higher than in other open-population cohorts but lower than in randomized controlled trials.
