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 antiaggre-gator 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 < 0.05). Con-clusion: The prognostic factors associated with the onset of post-infarction complications were ventricular arrhythmias (p < 0.04), atrial fibrillation (p = 0.01), the side effects of antiarrhythmics (p < 0.04), variability and turbulence of heart rate (

心肌梗死后患者死亡的预后因素:一项24小时节律性动态心电图观察研究

背景:心功能障碍和猝死是心肌梗死后常见的并发症。目的:本研究旨在通过确定与左心室功能障碍或梗死后猝死发生相关的因素，为改善患者的管理做出贡献。方法:采用横向、描述性和分析性研究，于2021年1 - 10月进行。结果:研究的变量包括流行病学、治疗和心电图方面。有102例患者在冠状动脉事件急性期后接受24小时心电图动态心电图检查，并入院接受近期血运重建性心肌梗死或非心肌梗死。研究人群中男性占88%，女性占12%，性别比为0.15。出院处方中抗心律失常药物占74%，抗血小板聚集药物占91%，抗凝药物占14%。电异常包括室上性心动过速45%，室外性心动过速61%，房颤19%，室上性心动过速11% (p < 0.05)。结论:与梗死后并发症发生相关的预后因素为室性心律失常(p < 0.04)、心房颤动(p = 0.01)、抗心律失常药物的副反应(p < 0.04)、心率变异性和湍流(p < 0.04)。
