Myocardial injury ‘contributes to COVID-19 mortality’
Elevated troponin T linked with a poor prognosis, find researchers
Myocardial injury may play a role in fatal outcomes of COVID-19, three reports in JAMA Cardiology suggest.
Doctors from Zhongnan Hospital of Wuhan University, China, investigated the association of underlying CVD and myocardial injury with fatal outcomes in 187 patients with COVID-19, of whom 35% had underlying CVD and 28% exhibited myocardial injury as indicated by elevated troponin T levels.
Mortality was markedly higher in patients with elevated plasma troponin T levels (60%) than in those with normal levels (9%).
Patients with elevated troponin T levels were older, more likely to be men and had significantly higher rates of comorbidities compared with patients with normal levels.
