Core Tip

Core Tip: This study aimed to analyze the relationship between the left ventricular ejection fraction (LVEF), left ventricular strain (LVS), and coronary artery stenosis (CAS), 93 healthy individuals were selected as the control group, while 97 patients with coronary heart disease were selected as the observation group. Through the analysis of the Gensini score, magnetic resonance imaging, a linear regression model, and Spearman’s correlation, we found that LVEF is significantly linearly correlated with LVS and negatively correlated with CAS.
