NPPB and coronary artery disorder: We used the univariate analysis to select the significant risk factors of CAD, and the results showed that male gender (OR 5.331, 95% CI 2.344–12.126, P < 0.001), BMI (OR 1.190, 95% CI 1.025–1.381, P < 0.05), cigarette smoking (OR 3.194, 95% CI 1.411–7.228, P < 0.01), HDL-C (OR 0.052, 95% CI 0.010–0.277, P < 0.01), BNP (OR 1.015, 95% CI 1.004–1.026, P < 0.01), and IGFBP1 (OR 1.091, 95% CI 1.041–1.144, P < 0.001) were significantly related to CAD.
