近年,对缺血性心脏病采取两种新的疗法,即冠脉溶栓法和血管整复术(Angioplasty)、前者系将链激酶静滴或经冠脉导管注入栓塞的冠脉内使急性血栓溶解;后者系通过冠脉导管尖端的特殊小囊打气以扩张冠脉狭窄部分,两者均可使冠脉再通,而避免冠搭桥手术。通过血管造影,冠脉粥样硬化最常发生在左前降支或左旋支的近端4cm以内,冠脉血栓形成与心肌梗塞的关系各家不一,由21％—97％(Hamby RI,1979),这种矛盾通过近年观察认为心肌
In recent years, two new therapies for ischemic heart disease have been taken, namely coronary thrombolysis and angioplasty. The former injects streptokinase intravenously or via coronary catheter into the embolized coronary artery to make acute Thrombolytic; the latter through the special tip of the coronary catheter balloon to expand the part of coronary artery stenosis, both of which can make the coronary recanalization, and to avoid the coronary bypass surgery. Coronary atherosclerosis most often occurs within 4 cm of the proximal left anterior descending branch or left circumflex artery through angiography. The relationship between coronary thrombosis and myocardial infarction varies from 21% to 97% (Hamby RI, 1979 ), This contradiction through the recent observation that myocardial
