Cardiovascular Complications in Respiratory Viral Infections with a Focus on COVID-19

Patients with respiratory viral infections have altered immune responses, which may predispose them to cardiovascular complications. in the face of the pandemic of a new kind of severe acute respiratory syndrome (sars), coronavirus disease 2019 (covid-19), there is a resurgence of interest in the early diagnosis, prevention, and treatment of patients who are at risk. covid-19 often manifests as viral pneumonia, although extrapulmonary manifestations are also common. acute cardiac damage associated with elevated highsensitivity troponin levels crucially contributes to mortality in severe covid-19. the present review clinically compares cardiovascular complications between covid-19 and other respiratory infections caused by singlestranded rna viruses, namely influenza, sars, and middle east respiratory syndrome (mers). estimating the death rate from rvis has been a subject of intense research, but the mortality from cardiovascular complications in these infections is less understood and calls for further research.
