Background:

cardiovascular diseases are considered a health problem worldwide, among them, acute myocardial infarction occupies a relevant place and represents one of the leading causes of death in most countries.

Objective:

to describe the clinical-epidemiological characteristics of patients admitted for ST-segment elevation acute coronary syndrome in the Cardiology Service and Coronary Care Unit of the Enrique Cabrera General Teaching Hospital in Havana.

Method:

a descriptive and cross-sectional study was carried out in patients diagnosed with ST-segment elevation acute coronary syndrome admitted to the coronary care unit from September 2018 to September 2021. 423 patients were studied and sociodemographic and clinical variables were analyzed. In the statistical analysis, the variables were expressed as mean for continuous variables and frequency and proportion for categorical variables, using the percentage as a summary measure. To quantify a possible risk, the Cross Products or Odd Ratio test was used with a 95 % confidence interval calculated by the Woolf method.

Results:

there was a predominance of males (71.2 %) and the average age was 62.31 years. 74.2 % of the patients had high blood pressure and 62.2 % were smokers. Heart failure, hypotension and pericarditis were presented as the most frequent complications. Treatment with thrombolytic therapy was administered in the majority of patients and mortality was 5.6 %.

Conclusions:

arterial hypertension and smoking predominated within the risk factors. Heart failure was the most frequent complication. Patients with extensive anterior infarction and diabetes mellitus had a higher probability of complications.
