OBJECTIVES This study prospectively examined whether the levels of high remnant-like lipoprotein particles (RLP) cholesterol have a significant risk and influence prognosis in patients with coronary artery disease (CAD) and type 11 diabetes mellitus (DM). BACKGROUND Several studies have shown that triglyceride-rich lipoproteins contribute to atherosclerotic complications in type 11 DM. However, it remains to be established which triglyceride-rich lipoproteins contribute to this risk. METHODS Levels of RLP cholesterol in fasting serum were measured by an immunoseparation method in 240 type 11 DM patients with (n = 120) or without (n = 120) CAD. The patients with CAD were followed up for a period of : 24 months until the occurrence of one of the following clinical coronary events: re-admission or coronary revascularization due to recurrent or refractory angina pectoris, nonfatal myocardial infarction, or cardiac death. RESULTS Patients with CAD had higher RLP levels than patients without CAD. Multivariate logistic regression analysis showed that high RLP cholesterol levels (>4.7 mg cholesterol/dl, representing the 75th percentile of the distribution of RLP cholesterol levels in control subjects) were a significant risk factor for the presence of CAD, independent of traditional risk factors. Kaplan-Meier analysis demonstrated that higher RLP cholesterol levels in patients with CAD resulted in a significantly higher probability for the development of coronary events. Multivariate Cox hazards analysis showed that high RLP cholesterol levels in patients with CAD were a significant predictor of future coronary events, independent of other risk factors. CONCLUSIONS Increased levels of RLP cholesterol are a significant and independent risk factor of CAD and predict future coronary events in patients with CAD and type 11 DM.
