Abstract

A cross-sectional study was conducted to investigate the characteristics and value of the LDL-C/HDL-C ratio in predicting the severity of coronary artery disease (CAD) as assessed by the Gensini score. The study was conducted on 226 patients (mean age 64.7 ± 8.0 years old, 69% male) with obstructive CAD. Patients were divided into two groups based on the median LDL-C/HDL-C ratio: low (≤ 2.11) and high (> 2.11). The LDL-C/HDL-C ratio was associated with BMI, diabetes mellitus, dyslipidemia, total cholesterol, HDL-C, triglycerides, statin or statin + ezetimibe treatment, and Gensini score (all p < 0.05). The LDL-C/HDL-C ratio was positively correlated with Gensini score (r = 0.34; p < 0.001). The area under the ROC curve for LDL-C/HDL-C ratio in predicting a high Gensini score was 0.633 with a cutoff point of > 1.91, sensitivity 76.9%, and specificity 47.7%. Multivariate regression analysis showed that LDL-C/HDL-C ratio was an independent predictor of a high Gensini score (odds ratio 2.5; p = 0.015). The LDL-C/HDL-C ratio was related to traditional cardiovascular risk factors and the severity of CAD, playing an important role in risk stratification and disease progression.
