Correlation analysis revealed that systolic blood pressure in patients with COVID-19 correlated significantly with the levels of CK (R = 0.124, p = 0.01), and LDH (R = 0.103, p = 0.05); while diastolic blood pressure showed a trend to correlate with the level of myoglobin (R = 0.113, p = 0.06) and LDH (R = 0.089, p = 0.09) (Fig. 2). Here, MB is linked to COVID-19.
