Correlation of troponin I and CK-MB with COVID-19 severity in seriously ill patients: A retrospective analysis from medical records.

COVID-19 is frequently associated with cardiovascular complications, with cardiac troponin I (cTnI) and CK-MB serving as markers of myocardial injury. Therefore, it is of interest to analyse of medical records from 300 PCR-confirmed COVID-19 patients admitted to High Dependency Unit (HDU) and Intensive Care Unit (ICU) during the second wave (2020-2021), biomarker levels at admission were correlated with disease severity. All patients included were seriously ill but survived. Severe cases had significantly higher cTnI and CK-MB levels (p < 0.001). These biomarkers provide important early prognostic information For the purpose of risk assessment and therapeutic treatment of COVID-19.
