Next, research of 880 COVID-19-positive patients pointed out that initial hs-cTnT (high-sensitivity cardiac troponin type T) was associated with composite adverse outcomes with a median hs-cTnT of 11 ng/L in patients who were living and did not require mechanical ventilation versus 31 ng/L in patients who expired or required mechanical ventilation [33]. Here, TNNT2 is linked to COVID-19.
