有关侧枝循环对冠状动脉粥样硬化患者发病率和死亡率的影响已争议了50年。作者先前的研究提示,侧枝循环的存在与否严重影响急性心肌梗塞(AMI)患者的长期预后。4年跟踪结果表明:梗塞冠脉远端灌注良好者,死亡率较小、相反冠脉仍闭塞,而其远端无灌注者,经常发生不稳定型心绞痛、AMI再发、充血性心衰和猝死。本研究评价梗塞冠脉侧枝究盈对AMI存活者死亡率的影响。对象与方法:研究对象为AMI患者146例(男性108例,女性38例),将患者分为2组。第1组为梗塞冠脉有侧枝充盈,共120例(男89,女31;平均年龄48±11岁);第2组梗塞冠脉无侧枝充盈,共26
The impact of collateral circulation on morbidity and mortality in coronary atherosclerosis has been controversial for 50 years. Previous studies by the authors suggest that the presence or absence of collateral circulation severely affects the long-term prognosis of patients with acute myocardial infarction (AMI). The results of 4 years follow-up showed that the distal perfusion of the infarcted coronary artery with a good mortality rate was relatively small. On the contrary, the coronary artery was still occluded. However, the patients with no distal perfusion had unstable angina, recurrent AMI, congestive heart failure sudden death. This study evaluated the effects of infarction-related collateral grafts on mortality in AMI survivors. Subjects and Methods: A total of 146 AMI patients (108 males and 38 females) were enrolled in this study. Patients were divided into two groups. Group 1 had collateral filling of the infarct coronary artery, a total of 120 cases (male 89, female 31; mean age 48 ± 11 years); the second group of infarction coronary artery without collateral filling, a total of 26
