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. ResultsIn 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 nonAslanger 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.
