摘要
目的 对比观察急性心肌梗死 (AMI)冠脉造影正常和异常患者的临床表现。方法 同期 14 4例AMI患者 ,于发病 12h内行尿激酶溶栓 ,并于心梗后 7～ 14d内行经皮冠状动脉造影术 ,梗死相关动脉 (IRA)再通且无冠脉病变者为冠脉正常组 ,再通且有冠脉病变及PTC成功者为冠脉异常组。记录二组患者易患因素 ,观察ST段抬高总和及 90min回落程度 ,比较二组住院期间心脏事件发生率 ,并于出院前行超声心动图检查。结果 14 4例患者中冠脉正常组 10例 ,冠脉异常组 134例 ,前者较后者年龄轻 ,男性 ,吸烟等诱因多见 ;造影时TMI 3级多见 ;ST段抬高总和于 90min回落明显 (P <0 .0 5 ) ;住院期间心脏事件发生率明显降低 (P <0 .0 5 ) ;出院前超声心动图提示左室射血分数较高 (P <0 .0 5 )。结论 AMI冠脉造影正常者相对年龄轻 ,吸烟诱因多 ,住院期间心功能和临床预后好。
Objective To observe presentations of acute myocardial infarction (AMI) with normal coronary artery. Methods 144 cases with AMI, who were treated with wokinare in 12 hours, performed coronary angiography after infarction 7～14days.According to coronary angiogram the patients were divided into group A (those with normal coronary artery) and group B(those with abnormal coronary artery). Results There were 10 case in group A and 134 case in group B. The group A had more males, more smokers, and more cases with TIMI3 flow in angiogram than those in group B. Compared with group B, the group A had much significant restortion of total elevation of ST segment at 90min(80% vs 56%,respectively, P<0.05),and fewer cardiac event (10% vs 46%,respectively,P< 0.05 ) during hospitalization. Before discharging echocardiography showed better left ventricular ejection fraction in group A than that in group B(0.56=0.1,0.47=0.09). Conclusion Patients of AMI with normal coronary artery have more males, more inducement,and better cardiac function and clinical outcome during hospitalization.
