ABSTRACT
Introduction: Cardiovascular diseases are the primary cause of death in developed and developing countries, being the acute myocardial infarction and its complications its greatest expression.Objective: To characterize patients with electrical complications of ST-segment elevation acute myocardial infarction admitted in the Coronary Intensive Care Unit of the Institute of Cardiology and Cardiovascular Surgery from October 2015 to 2017.
Methods: Descriptive, cross-sectional study of the medical records of 60 patients hospitalized in the Coronary Intensive Care Units in the Institute of Cardiology and Cardiovascular Surgery.
Results: In the anterior extensive infarction, 25 % of the cases had ventricular tachycardia and atrial fibrillation. Sinus bradycardia prevailed in cases of inferior myocardial infarction with or without right ventricle involvement, representing 33.3 % and 17.6%, respectively. Ventricular fibrillation (50 %) was the arrhythmia with the highest mortality; 3rd-degree atrioventricular block, atrial fibrillation, and ventricular tachycardia prevailed in the fibrinolytic reperfusion treatment (80.0 %; 75.0 % y 62.5 %, respectively).
Conclusions: Mortality was related to the development of malignant ventricular arrhythmia. Atrial fibrillation, ventricular tachycardia, and ventricular fibrillation remain challenges in the care protocols.
