Thus, the same method was applied in all enrolled subjects and coronary heart disease patients without kidney insufficiency, and in both groups, HDL-C/apoA-I levels increased significantly higher with lower Gensini scores (0.849 ± 0.127 and 0.877 ± 0.177, respectively, in all enrolled patients, P = 0.044; 0.816 ± 0.133 and 0.849 ± 0.129, respectively, in coronary heart disease patients without kidney insufficiency, P = 0.007). Here, APOA1 is linked to coronary artery disorder.
