Association of Socioeconomic Status With Risk Factor Target Achievements and Use of Secondary Prevention After Myocardial Infarction

Key Points Question Is socioeconomic status associated with 1-year target achievements and preceding secondary prevention activities after myocardial infarction? Findings In this nationwide cohort study of 30 191 survivors of first myocardial infarction, indicators of low socioeconomic status were associated with worse risk factor target achievements and with poorer use of secondary prevention. For instance, patients in the highest vs lowest quintile of disposable income had greater odds of smoking cessation and participating in patient educational sessions in cardiac rehabilitation. Meaning Observed disparities in target achievements and secondary prevention activities may be associated with worse long-term prognosis after myocardial infarction among individuals with lower socioeconomic status.
