Characteristics of the CAD group with LVSD and the CAD group with normal LVEF.

Data are shown as mean +/- standard deviation (SD) for quantitative variables and % for qualitative variables.CAD: coronary artery disease, HDL-c: high density lipoprotein cholesterol levels; LDL-c, low density lipoprotein cholesterol levels, LVSD: left ventricle systolic dysfunction, LVEF: left ventricle eject fraction.*Age at the first diagnosis of the disease for CAD cases and age at enrollment for CAD controls.†P values for comparison of means for quantitative data with a student t-test, and for comparison of distribution of qualitative variables between CAD patients with LVSD and CAD patients with normal LVEF with a Chi-square test.Characteristics of the CAD group with LVSD and the CAD group with normal LVEF.
