以晕厥为首发症状的急性心肌梗塞相关血管分析

Analysis of artery correlated with infarction in patients with acute myocardial infarction complicated syncope as primary symptom

目的:探讨以晕厥为首发症状的急性心肌梗塞(AMI)与梗塞相关血管之间的关系。方法:对200例急性ST段抬高型心肌梗塞(STEMI)并进行急诊经皮冠状动脉介入治疗(PCI)患者中15例以晕厥为首发症状的梗塞相关血管进行分析。结果:以晕厥为首发症状的患者在26例梗塞相关血管为左回旋支者中有5例(占19.2%);65例梗塞相关血管为右冠状动脉者中有7例(10.8%);109例梗塞相关血管为左前降支者有3例(2.8%),梗塞相关血管为左前降支者的晕厥为首发症状的发生率显著低于梗塞相关血管为右冠状动脉,及左回旋支者(P<0.05)。结论:梗塞相关血管为左回旋支或右冠状动脉的AMI患者,晕厥的发生率显著高于梗塞相关血管为左前降支的AMI患者。

Objective：To discover the relationship between acute myocardial infarction（AMI）patients complicated syncope as primary symptom and artery correlated with infarction.Methods：Among 200 consecutive acute ST elevation myocardial infarction（STEMI） patients undergoing primary percutaneous coronary intervention（PCI）,15 patients with syncope as primary symptom were analyzed for their arteries correlated with infarction.Results：There were five out of 26 AMI patients whose arteries correlated with infarction in left circumflex branch（LCB,19.2%）,a total of seven out of 65 AMI patients whose arteries correlated with infarction in right coronary artery（RCA,10.8%）,and three out of 109 AMI patients whose arteries correlated with infarction in left anterior descending branch（LAD,2.8%）with syncope as primary symptom.Incidence of syncope as primary symptom of artery correlated with infarction in LAD was significantly lower than that of LCB and RCA（P〈0.05 all）.Conclusion：The incidence of syncope as primary symptom of artery correlated with acute myocardial infarction in left circumflex branch or right coronary artery of patients is significantly higher than that of left anterior descending branch.
