本文旨在探讨心肌梗塞后室壁瘤的致死因素。室壁瘤59例,其中病理组27例,临床组32例。主要累及左室前壁。病理组单支、双支及三支冠状血管病变分别占10/27(37.0%)、9/27(33.3%)和8/27(29.7%)。重要的致死因素是泵衰竭、室颤和心脏破裂,分别占40.7%、33.3%和22.2%。临床组与病理组的临床特征及致死因素相比,无显著性差异。本文着重讨论致死因素发生机制,并指出消除致死因素是改善预后的关键。
This article aims to investigate the lethal factor of aneurysm after myocardial infarction. 59 cases of aneurysm, including pathological group of 27 cases, clinical group of 32 cases. Mainly involved the left ventricular anterior wall. Pathological group of single, double and three coronary vessels lesions accounted for 10/27 (37.0%), 9/27 (33.3%) and 8/27 (29.7%). Important lethal factors are pump failure, ventricular fibrillation and heart rupture, accounting for 40.7%, 33.3% and 22.2%, respectively. There was no significant difference between the clinical features and the lethal factors in the clinical and pathological groups. This article focuses on the mechanism of lethal factors and points out that the elimination of lethal factors is the key to improving prognosis.
