Because living alone is associated with an increased risk of type 2 diabetes mellitus in men but not women, living alone may be a risk factor of cardiovascular events after acute myocardial infarction (AMI) in diabetic men. The aim of the present study was to investigate the association between living alone and mid-term clinical outcomes after AMI in diabetic men. We conducted a single center, retrospecitve study. The primary endpoint was the major adverse cardiovascular events (MACE) defined as the composite of all cause death, AMI, and target vessel revascularization. A total of 253 AMI men with diabetes mellitus were included from our hospital records, and divided into the living together group (n = 203) and the living alone group (n = 50). Median follow-up duration was 239 days (Q1: 94 days, Q3: 451 days). A total of 66 MACE was observed during the study period, and Kaplan-Meier curves were constructed to compare the MACE. The MACE was more frequently observed in the living alone group than the living together group (P = 0.041). Multivariate Cox regression analysis revealed that the living alone group was significantly associated with the MACE (Odds ratio: 1.770, 95% confidence interval 1.018-3.077, P = 0.043) after known clinical risk factors. In conclusion, living alone was significantly associated with the mid-term MACE after AMI in diabetic men. It may be important to provide multiple interventions including lifestyle guidance as well as sufficient acute medical care for such high-risk patients.
