Objective: Myocardial injury leads to higher mortality in COVID-19, but the causes and risk factors are variable. We evaluated the potential risk factors for myocardial injury in COVID-19 patients to improve treatment strategies and reduce mortality.
Methods: This retrospective analysis enrolled 325 COVID-19 patients in Shanghai, China.
Results: The median age in our cohort was 51 [range 15-88] years, 26 (8%) were critically ill, and 177 patients (19.7%) had myocardial injury. The myocardial injury group comprised older, more critically ill patients with hypertension, other comorbidities, history of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use, lower peripheral blood lymphocyte count and higher D-dimer levels. Binary logistic regression analysis identified only age was an independent risk factor for myocardial injury (odds ratio 1.019; 95% confidence interval 1.003-1.036; age increase by 1 year = myocardial injury risk increase by 1.9%).
Conclusions: Older age was associated with a higher incidence of myocardial injury for COVID-19 patients.
