Value of ST segment elevation in lead aVR of electrocardiogram in the assessment of coronary artery stenosis and cardiac function of patients with myocardial infarction
Objective
To evaluate the effect of ST segment elevation in lead aVR of electrocardiogram in the assessment of coronary artery stenosis and cardiac function of patients with myocardial infarction.
Methods
The clinical data of 75 patients with myocardial infarction admitted to the Third People’s Hospital of Liaocheng from January 2018 to January 2019 were analyzed retrospectively, according to the ST segment elevation of aVR lead, the participants were divided into ST segment elevation group (n=26) and non ST segment elevation group (n=49), the location of coronary artery stenosis, cardiac function index and the occurrence of cardiovascular events were compared between the two groups.
Results
According to the examination, the proportion of coronary artery stenosis in the left main trunk and the proximal part of left anterior descending artery in ST segment elevation group was higher than that in non ST segment elevation group, and the proportion of the distal part of left anterior descending artery was lower than that in non ST segment elevation group (P<0.05); 6-minute walking distance of ST segment elevation group was shorter than that of non ST segment elevation group (P<0.05); left ventricular ejection fraction (LVEF) was lower than that of non ST elevation group (P<0.05); the values of left ventricular end systolic diameter (LVESD) and left ventricular end diastolic diameter (LVEDd) in ST segment elevation group were significantly higher than those in non ST segment elevation group (P<0.05); the total incidence of cardiovascular events in ST elevation group was higher than that in non ST elevation group (P<0.05).
Conclusions
ST segment elevation in lead aVR of ECG can effectively judge the location of coronary artery stenosis in patients with myocardial infarction, and provide effective reference for clinical diagnosis and treatment.
