Compared with patientswithout functionally significant coronary disease, patients with functionallysignificant coronary disease had a significantly higher high-sensitivity cardiac troponin I (hs-cTnI) (p =0.011), with an average value of 0.85 ± 0.331 ng/mL There were nostatistically significant differences in blood glucose, blood lipids, B-type natriuretic peptide (BNP), andthyroid function between the two groups. The gene discussed is NPPB; the disease is coronary artery disorder.
