Thelevel of N-terminal pro-b-type natriuretic peptide (median 241.0 versus 33.5pg/mL, p< 0.05), C-reactive protein (median 4.8 versus 2.0 mg/L,p< 0.05), D-dimer (median 1.2 versus 0.2 μg/mL, p< 0.05)in patients with COVID-19-related AVB were substantially higher than controls.The details of characteristics of 9 COVID-19-related AVB patients and controlsfor proteomics analysis are listed in Table 2. The gene discussed is CRP; the disease is atrioventricular block.
