The independent t test and chi-square test analysis showed that the CVC group was older and had higher rates of smoking, DM, lower extremity arterial occlusion, CHD, and CAC but lower PTH, serum Ca, Mg, Alb, pre-Alb, and HDL-C levels than in non-CVC group (P < 0.05). This evidence concerns the gene ALB and coronary artery disorder.
