本文分析了259例60岁以下急性心肌梗塞存活者梗塞后严重左室功能障碍的发生率和预后。本文研究目的在于:①明确梗塞后严重左室功能障碍的发生率;②描述该组患者冠状动脉解剖特征;③测定非致命性新的冠状动脉病变发生率;④采用 Cox氏回归分析以确定存活者的单独预后判定指标。方法:选择1975年12月～1979年3月住入冠心病监护病室的60岁以下急性心肌梗塞患者300例,均男性。在284例存活者中,去除21例拒绝冠状动脉
This article analyzes the incidence and prognosis of severe left ventricular dysfunction after infarction in 259 survivors of acute myocardial infarction under 60 years of age. The purpose of this study is to: (1) identify the incidence of severe left ventricular dysfunction after infarction; (2) describe the anatomical characteristics of coronary arteries in this group; (3) determine the incidence of non-fatal new coronary lesions; (4) use Cox’s regression to determine survival The individual prognostic indicators. Methods: 300 patients with acute myocardial infarction under 60 years of age admitted to coronary care unit from December 1975 to March 1979 were selected, all of whom were male. Of the 284 survivors, 21 rejected the coronary artery
