摘要
目的探讨完全闭塞性和几乎完全闭塞性病变ＰＴＣＡ成功率及其影响因素。方法对３５例发生过心肌梗塞和２１例未发生心肌梗塞的完全或几乎完全闭塞性病变施行了ＰＴＣＡ。结果完全闭塞性病变心梗发生后１周内ＰＴＣＡ成功率为１００％，２周～３个月为６６．７％，３个月以后为４２．９％；无桥侧支的几乎完全闭塞性病变ＰＴＣＡ成功率为１００％，桥侧支丰富的几乎完全闭塞性病变ＰＴＣＡ成功率为６２．５％。结论心肌梗塞早期ＰＴＣＡ成功率明显高于心肌梗塞晚期ＰＴＣＡ成功率（Ｐ＜０．０５），无桥侧支的几乎完全闭塞性病变ＰＴＣＡ成功率明显高于桥侧支丰富的几乎完全闭塞性病变的成功率（Ｐ＜０．０５）
PTCA was performed on 35 patients with and 21 patients without a history of myocardial infarction All patients had a total or sub total coronary occlusion The success rate of PTCA within 1 week of AMI was 100%, between two weeks and three months was 66 7%, over six months after AMI was 42 9%; The success rate of PTCA of subtotal coronary occlusion without collateral circulation was 100%, with abundant collateral circulation was 62 5% The success rate of PTCA performed in the earlier stage was significantly higher than that performed in the later stage after AMI ( P <0 05), that of sub total coronary occlusion without collateral circulation was obviously higher than that of lesion with abundant collateral circulation ( P <0 05)
