Aslanger征提示急性下壁心肌梗死严重程度的评价

Evaluation of Severity of Acute Inferior Myo-cardial Infarction Suggested by Aslanger Sign

摘要: 目的：探讨体表心电图Aslanger征对下壁心肌梗死的临床预测价值。方法：总共69例急性下壁心肌梗死患者纳入本研究，对比分析Aslanger征组与非Aslanger征组之间临床结果的差异。结果：69例患者中20例表现为Aslanger征下壁心肌梗死，20例Aslanger征患者中14例(70%)患者患有糖尿病病史，8例(40%)患者左心室射血分数 ≤ 48%，11例(55%)患者N未端脑钠肽前体(NT-ProBNP) ≥ 800 pg/ml，13例(65%)患者急诊冠脉造影显示存在两支以上病变，全部患者进行了急诊冠脉介入手术(PCI)。Aslanger组与非Aslanger组间多项临床指标比较存在统计学差异(均P值 < 0.05)。结论：Aslanger征提示下壁心梗的病情相对严重，具有较好的临床预测价值。

Abstract: Objective: To investigate the clinical value of Aslanger sign of surface electrocardiogram in predict-ing inferior myocardial infarction. Methods: A total of 69 patients with acute inferior wall myocardi-al infarction were included in this study, and the difference of clinical outcomes between the Aslanger sign group and the non-Aslanger sign group was analyzed. Results: Twenty of the 69 pa-tients presented with inferior myocardial infarction caused by Aslanger’s sign, 14 (70%) of the 20 patients with Aslanger’s sign had a history of diabetes, and 8 (40%) had left ventricular ejection fraction ≤ 48%; eleven patients (55%) had N-terminal pro-brain natriuretic peptide (NT-ProBNP) ≥ 800 pg/ml, 13 patients (65%) had more than two branches of disease on emergency coronary an-giography, and all patients underwent emergency coronary intervention (PCI). There were statisti-cal differences in many clinical indexes between Aslanger group and non-Aslanger group (all P val-ues < 0.05). Conclusion: Aslanger sign indicates that the condition of inferior wall myocardial infarc-tion is relatively serious and has good clinical value.
