Abstract
Background: Heart dysfunction and sudden death are common complications in post-myocardial infarction. Purpose: This study aims to contribute to improving patient’s management by determining the factors correlated to the occurrence of left ventricular dysfunction or post-infarction sudden death. Method: It was a transversal, descriptive and analytical study conducted from January to October 2021. Results: The variables studied covered epidemiological, therapeutic and electrocardiographic aspects. There were 102 patients admitted for a recent revascularized myocardial infarction or not who had received a 24-hour ECG Holter after the acute phase of coronary event. The study population was predominantly men 88% versus 12% women with a sex ratio of 0.15. The discharge prescription was 74% antiarrhythmic, 91% platelet antiaggregator and 14% anticoagulant. Electrical abnormalities consisted of supraventricular extrasystoles in 45% of cases, ventricular extrasystoles in 61%, atrial fibrillation in 19% and supraventricular tachycardias in 11% (p Conclusion: The prognostic factors associated with the onset of post-infarction complications were ventricular arrhythmias (p
