Furthermore, although the comparable LVEF between the two groups (P = 0.564), patients with stable CAD had significantly elevated concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP) in contrast to individuals without CAD (P < 0.001), with mean values and 95% confidence intervals (CI) of 724.5 [276.0, 1836.5] pg/ml and 321.0 [120.0, 769.5] pg/ml, respectively. The gene discussed is NPPB; the disease is coronary artery disorder.
