Apolipoprotein A1 Is a Stronger Prognostic Marker Than Are HDL and LDL Cholesterol for Cardiovascular Disease and Mortality in Elderly Men

• The aim of this study was to compare apolipoprotein A1 (ApoA1) and B (ApoB) with high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) as markers for cardiovascular mortality and morbidity in elderly men. We analyzed serum ApoA1, ApoB, total cholesterol, HDL-C, and LDL-C in a group of 77-year-old men (n = 785). The results were correlated with data from the Swedish cause of death registry. Receiver-operating characteristic curves showed that, of the studied serum markers, ApoA1 was the best predictor for ischemic heart disease mortality (area under the curve = 0.724, 95% confidence interval, 0.691-0.755). There were also significant correlations between the apolipoproteins and other known risk markers for cardiovascular disease such as triglycerides, high-sensitivity C-reactive protein (hsCRP), and cystatin C. Serum ApoA1 is a better risk marker than are ApoB, ApoB/ApoA1 ratio, HDL-C, and LDL-C for cardiovascular disease and mortality in elderly men.
