A recent systematic review and meta-analysis (Ma et al., 2021) performed in about 64.000 COVID19 patients found that elevated myoglobin levels was a more common finding than elevated cardiac troponin I (TnI) in patients with severe COVID19 and that elevated myoglobin levels were also associated with higher odds of severe illness and mortality than TnI. This evidence concerns the gene TNNI3 and COVID-19.
