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<0.01) than of diabetic AMI patients without hypertension. Although no statistically significant differences were found in the other variables between the groups, smoking, hypertension and dyslipidemia were more prevalent in diabetic than in non-diabetic patients with AMI undergoing MRS.

Conclusion

The prevalence of MRS after AMI in diabetic patients was higher than in non-diabetic patients.
