MB and heart failure: Patients with heart failure and SARS-CoV-2 infection had not only increased serum inflammatory markers, but also elevated cardiac injury markers, including CK-MB (median value 33 U/L vs. 26 U/L, p-value = 0.015), myoglobin (median value 3.9 nmol/L vs. 3.5 nmol/L, p-value = 0.023), troponin I (median value 0.5 ng/mL vs. 0.3 ng/mL, p-value = 0.040), and troponin T (median value 16 ng/mL vs. 12 ng/mL, p-value = 0.037).
