Cardiovascular Manifestations of COVID-19

Coronavirus disease 2019 (COVID-19) first emerged in a group of patients who presented with severe pneumonia in Wuhan, China, in December 2019. A novel virus, now called SARSCoV- 2 (Severe Acute Respiratory Syndrome Coronavirus-2), was isolated from lower respiratory tract samples. The current outbreak of infection has spread to over 100 countries and killed more than 340,000 people as of 25^th May, 2020. The predominant clinical manifestation of COVID-19 is a respiratory disease- ranging from mild flu-like symptoms to fulminant pneumonia and Acute Respiratory Distress Syndrome (ARDS). Patients with pre-existing cardiovascular risk factors are considered more susceptible to the virus, and these conditions are often worsened by the infection. Furthermore, COVID-19 infection has led to de novo cardiac complications, like acute myocardial injury and arrhythmias. In this review, we have focused on the cardiovascular manifestations of COVID-19 infection that have been reported in the literature so far. We have also outlined the effect of pre-existing cardiovascular disease as well as risk factors on the clinical course and outcomes of COVID-19 infection.
