冠脉侧枝循环对缺血性心脏病的进展和预后影响较大。本文探讨了心肌梗塞例其梗塞前心绞痛的发生对冠脉侧枝循环的建立、左室射血分数、梗塞局部射血分数的影响及与梗塞后心绞痛发生的关系。1983年6月至1988年3月间在日本金沢大学第二内科行冠脉造影的陈旧性心肌梗塞共35例,均符合下列条件:(1)引起梗塞的主要冠脉为左前降支和右冠状动脉的近端闭塞;(2)梗塞发生后冠脉造影结果为主要冠脉
Coronary collateral circulation has a greater impact on the progression and prognosis of ischemic heart disease. This article discusses the incidence of myocardial infarction in patients with its pre-infarction on the establishment of coronary collateral circulation, left ventricular ejection fraction, partial ejection fraction of infarction and its relationship with the occurrence of post-infarction angina. Between June 1983 and March 1988, 35 patients with old myocardial infarction underwent coronary angiography at the Second Internal Medicine Section of the Second Military Medical University in Japan met the following criteria: (1) The major coronary arteries causing the infarction were left anterior descending artery and right Proximal occlusion of coronary artery; (2) coronary angiography after infarction as the main coronary artery
