【摘要】 目的 探讨体表心电图Aslanger征对急性下壁心肌梗死(acute inferior myocardial infarction, AIMI)的临床预测价值。方法 收集150例AIMI患者在冠状动脉开通前的第一份心电图，分为Aslanger征组(9例)与非Aslanger征组(141例)。对比分析两组冠状动脉造影结果、左心室射血分数、血压和心率、Killip分级、cTnI、肌酸激酶同工酶、NT-proBNP水平等的差异。结果 Aslanger征组cTnI、NT-proBNP水平以及临床Killip分级中Ⅲ—Ⅳ级病例占比均明显高于非Aslanger征组(P<0.05)。急诊冠状动脉造影显示，Aslanger征组双支和三支病变患者比例明显高于非Aslanger征组(双支病变：55.56%vs.17.02%;三支病变：33.33%vs. 2.83%,P<0.05)。结论 出现Aslanger征的AIMI患者病情相对严重，心功能更差，更容易存在两支及以上的冠状动脉病变。更多还原

【Abstract】 Objective To explore the clinical value of Aslanger pattern of body surface ECG in predicting acute inferior myocardial infarction(AIMI). Methods We collected 150 ECGs of patients with AIMI which had been firstly recorded before coronary artery opening. These patients were divided into Aslanger pattern group(9 cases) and non-Aslanger pattern group(141 cases). We compared and analyzed coronary angiography results, left ventricular ejection fraction, blood pressure and heart rate, Killip calssification, cTnI, CK-MB and NT-proBNP levels, etc. between the two groups. Results In the Aslanger pattern group, cTnI and NT-proBNP levels, and the proportion of patients at Ⅲ-Ⅳ level of Killip classification are all significantly higher than those in the non-Aslanger pattern group(P<0.05). Emergency coronary angiography reveals in the Aslanger pattern group, the proportion of patients with coronary lesions in two and three branches are both significantly higher than those in the non-Aslanger pattern group(lesions in two branches: 55.56% vs. 17.02%; lesions in three branches: 33.33% vs. 2.83%,P<0.05). Conclusion The concomitant Aslanger pattern in AIMI patients indicates more severe condition, worse cardiac function, and more likely to be found no less than two branches of coronary artery lesions.更多还原
