急性心肌梗塞伴发束支传导阻滞(BBB)提示左前降支供血区心肌缺血,然而慢性冠心病合并,BBB是否以左前降支病变为主尚无定论。同样地临床研究大多注重急性心肌梗塞患者伴发BBB后的预意义,至于慢性冠心病患者合并BBB的预后意义所知甚少。作者回顾冠(状动)脉外科研究登记处卷宗,1974年6月致1979年5月间,54±9岁的15609(男13181、女2428)例慢性冠心病患者资料齐备,经冠
Acute myocardial infarction with bundle branch block (BBB) suggests myocardial ischemia in the left anterior descending coronary artery. However, it is still not known whether BBB is associated with left anterior descending coronary artery disease. Similarly, most clinical studies focus on the pre-definition of patients with acute myocardial infarction associated with BBB, and little is known about the prognostic significance of BBB in patients with chronic coronary artery disease. Review of the Coronary Artery Surgery Registry, June 1974 To May 1979, data on 15,609 (13181, 2428) 548-year-old patients with chronic coronary artery disease at 54 ± 9 years of age were available,
