During the outbreak of wild-type SARS-CoV-2 in Wuhan, Shi et al. found that advanced age, pre-existing diseases (e.g., hypertension, coronary artery disease, chronic renal failure, and chronic obstructive pulmonary disease), and inflammatory markers (procalcitonin and CRP) were predictors of in-hospital myocardial injury among patients with severe COVID-19 (5). Here, CRP is linked to chronic kidney disease.
