Potential adverse effects of coronavirus disease 2019 on the cardiovascular system.

Coronavirus disease 2019 (COVID-19) has spread, at an unprecedented speed and scale, into a global pandemic, infecting more than 29 million cases worldwide across 215 countries and territories and killing more than 930,000 individuals. There is evidence that preexisting cardiac disease can render individuals vulnerable. A large number of patients with COVID-19 present with preexisting cardiovascular disease or develop new-onset cardiac dysfunction during the course of the illness. Therefore, particular attention should be given to cardiovascular protection during COVID-19 treatment. This review highlights recent advances in our understanding of the interaction between COVID-19 and the cardiovascular system, with special attention to the virological, pathological, and immunological characteristics of COVID-19, acute myocardial injury, myocarditis, arrhythmias, coronary artery disease, heart function, and the possible mechanisms.
