ECG Detection of Aslanger Sign Suggests the Value of Acute Inferior Myocardial Infarction with Other Serious Coronary Lesions
Objective:To analyze the clinical predictive value of electrocardiogram detection of Aslanger sign for acute inferior myocardial infarction(AIMI)complicated with other severe coronary artery lesions.Methods:100 AIMI patients were selected as the research subjects and treated from May 2021 to May 2022.According to the results of the first electrocardiogram examination,39 patients with Aslanger sign were included in the experimental group,and 61 patients without Aslanger sign were included in the control group.Perform electrocardiogram and coronary angiography tests on two groups of patients separately,compare the results of the two groups,and simultaneously detect cardiac markers(cTnl,CK-MB,NT-proBNP,LVEF)in the two groups of patients and compare them.Results:Patients in the experimental group were more prone to STv3R-v5R↑,STv7-v9↑,STv4-v6↓,STV1↑,and STavF↓ compared to the control group,with statistically significant differences(P<0.05).However,there was no significant difference in STv1-v3↓ between the two groups(P>0.05);The proportion of patients with proximal right coronary artery(RCA)infarction in the experimental group was 82.05%(32/39),which was higher than the control group's 42.62%(26/61).The proportion of patients with distal RCA and left coronary artery circumflex branch(LCX)was lower than that in the control group(P<0.05);The degree of coronary artery stenosis in the experimental group was more severe than that in the control group,and the proportion of double vessel and triple vessel lesions was significantly higher than that in the control group;The cardiac function indicators of the experimental group were lower than those of the control group.Conclusion:AIMI patients with Aslanger sign often have a higher risk of developing coronary artery stenosis and other coronary artery lesions.Patients have poorer heart function and are more likely to develop two or more coronary artery lesions than those without Aslanger sign.This can directly reflect the severity of AIMI patients and has high value for clinical condition evaluation.
