cTnT was significantly positively correlated with the following risk factors (Coronary heart disease: ρ = 0.302, p < 0.01; Insular cortical lesions: ρ = 0.329, p < 0.01; Peak NT-proBNP: ρ = 0.538, p < 0.01; C-reactive protein: ρ = 0.436, p < 0.01; NIHSS score: ρ = 0.378, p < 0.01). The gene discussed is NPPB; the disease is coronary artery disorder.
