Prevalence of Surgical Myocardial Revascularization in Diabetics and Non-diabetics After Acute Myocardial Infarction

Abstract Background Diabetes mellitus (DM) is a metabolic disorder characterized by persistent hyperglycemia. The main cause of death among diabetics is cardiovascular disease (CVD), which is a precursor to acute myocardial infarction (AMI). Approximately 30% of diabetic patients with AMI require myocardial revascularization surgery (MRS). Objective To evaluate the prevalence of MRS in diabetic and non-diabetic patients after AMI in a hospital in the city Criciúma, Brazil, during the period from 2016 to 2019. Methods A cross-sectional study was carried out with secondary data collection, with analysis of 215 medical records of diabetic and non-diabetic patients with AMI, submitted or not to MRS during the study period. For statistical analysis, the Shapiro-Wilk test, Pearson’s chi-square test and Fisher’s exact test were used, with a significance level of α = 0.05. Results The frequency of diabetic AMI patients with hypertension (88.1%) was significantly higher (p
