    Acute myocardial infarction (AMI) recurrence is still high despite great progress in secondary prevention. Patients with recurrent AMI suffer worse prognosis compared to those with first AMI. The objective was to evaluate the effect of optimal medical therapy (OMT) on these patients with recurrent AMI.

    Aims We aimed to explored the association between the use of optimal medical therapy (OMT) in patients with myocardial infarction (AMI) and diabetes mellitus (DM) and clinical outcomes. Methods Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome (BleeMACS) is an international registry that enrolled participants with acute coronary syndrome followed up for at least 1 year across 15 centers from 2003 to 2014. Baseline characteristics and endpoints were analyzed. Results Among 3095 (23.2%) patients with AMI and DM, 1898 (61.3%) received OMT at hospital discharge. OMT was associated with significantly reduced mortality (4.3% vs. 10.8%, p < 0.001), re-AMI (4.4% vs. 8.1%, p < 0.001), and composite endpoint of death/re-AMI (8.0% vs. 17.6%, p < 0.001). No difference was observed among regions. Propensity score matching confirmed that OMT significantly associated with lower mortality. After adjusting for confounding variables, OMT, drug-eluting stents, and complete revascularization were independent protective factors of 1-year mortality, whereas left ventricular ejection fraction and age were risk factors. Conclusions Guideline-recommended OMT was prescribed at suboptimal frequencies with geographic variations in this worldwide cohort. OMT can improve long-term clinical outcomes in patients with DM and AMI.
