Introduction: Acute Myocardial Infarction (MI) is characterized by a process of ischemic necrosis. This ischemia results from a pathophysiological basis and/or from predisposing factors, such as Diabetes Mellitus (DM). In this context, it is evident that patients with type 2 DM have two to four times greater risk of mortality from Cardiovascular Diseases (CVD) than patients who do not have this condition. Objective: To identify the variation of mortality rate due to Acute Myocardial Infarction in young adults with DM according to the Brazilian region, gender and ethnicity. Method: This is a descriptive cross-sectional study of deaths due to acute myocardial infarction in young patients, with diagnosis of DM in Brazil, between January 2016 and April 2021. Results: 6 articles were chosen to compose the final sample. Prevalence of death and mortality rate due to AMI were observed in male, older age, and dark-skinned (mainly black and brown) patients. Independent of DM, mortality after MI remained low in young adults. Conclusion: DM in young adults was associated with high rates of circulatory diseases. Complications in specific groups caused serious clinical cases, as verified in the AMI. The populations with prevalence of mortality were male, older, black and brown.
