Aim: Type 2 diabetes mellitus (T2DM) is a risk factor for mortality after acute myocardial infarction (AMI). We studied the impact of T2DM related to sex and age on post-AMI long-term mortality. Methods: A retrospective study included post-AMI patients. Data were obtained from electronic medical records. We defined the study groups by T2DM, stratified by age-sex. Outcome: up-to-10 years post-discharge all-cause mortality. Results: 16,168 patients were analyzed, 40.3% had T2DM. Ten-year mortality rates were 50.3% with T2DM vs. 33.1% without T2DM, adjHR = 1.622 (p < 0.001). Females (adjHR = 1.085, p = 0.052) and increased age (adjHR = 1.056 for one-year increase, p < 0.001) were associated with a higher risk of mortality (borderline statistical significance for sex). The relationship between T2DM and mortality was stronger in females than in males at < 50 and 60–69 years (p-for-interaction 0.025 and 0.009 respectively), but not for other age groups. Conclusions: The study implies heterogeneity in the impact of T2DM on mortality of post-AMI patients, being greater among young patients, particularly females, and no significant impact in octogenarians. That implies that young women with T2DM should have advanced measures for early detection of coronary artery disease and tight control of cardiovascular risk factors to lower the propensity to develop AMI.
