BACKGROUND: Coronary atherosclerosis and recurrent cardiovascular events are common among individuals with type 2 myocardial infarction (T2MI). However, cardiovascular resource utilization among T2MI patients is unclear. OBJECTIVES: The aim of the study was to characterize cardiovascular resource utilization among T2MI patients across the United States. METHODS: Using Optum's de-identified Clinformatics Data Mart Database, cardiovascular procedures, physician services, and prescriptions within 6 months postdischarge were compared among patients with T2MI vs type 1 myocardial infarction (T1MI) between October 1, 2017, and June 30, 2020. Multivariable logistic regression examined the odds of resource utilization in T2MI vs T1MI and identified predictors of utilization for T2MI. RESULTS: We identified 140,344 patients with myocardial infarction
121,738 patients (87%) had T1MI and 18,606 (13%) had T2MI. All participants had 183 days of postdischarge follow-up. Within 6 months postdischarge, patients with T2MI were significantly less likely to fill new prescriptions for P2Y CONCLUSIONS: In the United States, T2MI patients received less cardiovascular testing and secondary preventative therapies than T1MI patients.
