Introduction:

The risk of developing an acute myocardial infarction is related to the presence of cardiovascular risk factors that have a cumulative effect, many of which are preventable.

Objectives:

To describe the characteristics of patients with acute myocardial infarction at the Hospital Nacional of Itauguá, Paraguay, in the period 2020-2021.

Methods:

An observational, descriptive study with an analytical component was carried out. Men and women, of legal age, with acute myocardial infarction were included. The research was approved by the Ethics Committee of the National University of Itapúa.

Results:

The sample consisted of 110 patients, with a mean age of 64 years, 68.2% were male, 83.6% came from urban areas and 61.8% had a primary education level. Comorbidity was present in 92.7%, the most frequent being arterial hypertension. A previous cardiovascular event was observed in 22.7% and 63.6% had non-ST-elevation infarction. Fibrinolytic therapy was used in 12 of 40 patients with ST elevation myocardial infarction. Coronary angiography was performed in 45.5%. Mortality was 20% and was associated with advanced age, anemia, low ejection fraction, Killip Kimball class III and IV, and presence of diabetes mellitus (p<0.05). The presence of obesity, smoking, arterial hypertension, type of infarction and hours of evolution before consultation were not associated with mortality (p>0.05).

Conclusion:

Non-ST-elevation acute myocardial infarction predominated. Overall mortality was 20% and its predictive factors were diabetes mellitus, Killip Kimball class III and IV at admission, ejection fraction ≤40%, hemoglobin ≤10.1 g/dL, and advanced age.
