SPP1 and coronary stenosis: Univariant regression analysis suggested that serum uric acid plasma levels were directly related to osteopontin (r = 0.536, P < 0.001), LD-CAP (r = 0.424, P < 0.001), Agatston' score index (r = 0.372, P = 0.016), type two diabetes mellitus (r = 0.205, P = 0.055), total cholesterol (r = 0.326, P < 0.001), osteopontin (r = 0.246, P = 0.027), coronary artery stenosis of more 50% (r = 0.286, P = 0.012), eGFR (r = 0.348, P < 0.001), and creatinine plasma level (r = 0.321, P < 0.001) and inversely correlated to LVEF (r = −0.735, P < 0.001).
