Abstract

Among statin-treated patients with type 2 diabetes mellitus (T2DM), there is still a great residual cardiovascular risk. Previous studies found that the level of remnant cholesterol (RC) could predict the coronary artery disease (CAD) risk. In the present study, we enrolled 4145 patients with T2DM; 2784 (67.2%) were male and their median age was 62 years. After multivariate logistic analyses, plasma RC level was significantly and independently associated with CAD [odds ratio (OR) 13.524, 95% confidence interval (CI) = 7.058-25.912, P < .001) after adjustment for conventional risk factors, such as age, gender, hypertension, and other lipid levels. Even in the presence of high high-density lipoprotein cholesterol (HDL-C) level, the elevated RC could still predict CAD in T2DM patients (OR 2.064, 95%CI 1.438-2.964, P < .001). Furthermore, RC had relationships with age, hypertension, and smoking status in promoting CAD progression in T2DM patients, with all p for interactive <.001. In conclusion, RC level was independently associated with CAD risk in patients with T2DM.
