比较直接ＰＴＣＡ和尿激酶静脉溶栓对ＡＭＩ患者的治疗作用。将ＡＭＩ分为直接ＰＴＣＡ组（２７例）和尿激酶静脉溶栓组（２８例），观察冠脉再通率、住院死亡率和再次梗塞率、出院前左室ＥＦ。发现直接ＰＴＣＡ组冠脉再通率明显高于静脉溶栓组，住院期间死亡率、再梗塞率明显低于静脉溶栓组，直接ＰＴ－ＣＡ组左心室ＥＦ显著高于静脉溶栓组。本研究提示：ＡＭＩ患者行直接ＰＴＣＡ可能较静脉溶栓治疗更能挽救阻塞血管区域的心肌
To compare the therapeutic effect of direct PTCA and urokinase intravenous thrombolysis in patients with AMI. AMI was divided into direct PTCA group (n = 27) and urokinase intravenous thrombolysis group (n = 28). The coronary recanalization rate, hospital mortality and re-infarction rate were observed. It was found that the recanalization rate of coronary artery in direct PTCA group was significantly higher than that in intravenous thrombolytic group. The mortality and re-infarction rate during hospitalization were significantly lower than those in intravenous thrombolysis group. The left ventricular EF in direct PT-CA group was significantly higher than that in intravenous thrombolysis group. This study suggests that direct PTCA in patients with AMI may be more effective than venous thrombolysis in the rescue of myocardial infarction
