Introduction:

Within cardiovascular diseases, acute myocardial infarction is one of the most important causes of death in Cuba, with a growing trend in the period 2019-2020.

Objective:

To identify the variables associated with early morbidity and mortality due to acute myocardial infarction, in the coronary unit of the Clinical Surgical University Hospital Faustino Pérez Hernández, in the period 2019-2020.

Materials and methods:

Observational, descriptive, and cross-sectional study that included 150 patients. Qualitative and quantitative variables were analyzed, Chi-square or T-student tests were applied to them, and a binary logistic regression was performed. A statistical significance level of p<0.05 was used.

Results:

27 % of the patients presented complications, and mortality was 6%. The variables that were related to complications were age 60 years or older (OR=3.27; p=0.004), location of the infarct on the anterior wall (OR=2.63; p=0.013) and the left ventricular ejection fraction less than 40% (OR=4.82, p=0.005).

Conclusions:

Advanced age, location of the infarct on the anterior wall, and systolic ventricular dysfunction were associated with higher early morbidity and mortality.
