Core Tip

Core Tip: We systematically reviewed the literatures to assess this claim that an increase in troponin-I levels could be a prognostic factor in predicting disease severity and mortality in patients with coronavirus disease 2019. According to our findings, regardless of the history of myocardial injuries or the presence of cardiovascular risk profile, the value of troponin I should be accurately assessed on admission. Raising troponin-I on admission can be linked to the increase risk for in-hospital death, acute respiratory distress syndrome, kidney injury, and intensive care unit admission by 4.9, 5.9, 3.8, and 3.7 times as compared to those with initial normal troponin I concentration.
