The PMI group had higher number of male patients (74.4% vs. 56.4%, p = 0.001) and higher number of patients with diabetes mellitus (20.5% vs. 8.2%, p = 0.001), coronary heart disease (CHD; 28.2% vs. 17.1%, p = 0.013), and partial laboratory findings (creatine kinase, myoglobin, lactic dehydrogenase, homocysteine, high‐sensitivity troponin T, and brain natriuretic peptide, all p < 0.05) than the non‐PMI group. This evidence concerns the gene NPPB and coronary artery disorder.
