[Comment on the article "Severe coronavirus-2 infection background for cardiovascular complications"].

Current information is presented on a phenomenon that occurs in patients who had COVID-19 that could contribute to long-term cardiovascular risk. It deals with the mechanisms underlying cardiovascular and coagulation alterations that perpetuate cardiac symptoms caused by alterations induced by the virus or by myocardial inflammation, such as cardiac endothelial dysfunction, which could cause vascular microthrombosis. The intentional search for this in patients under follow-up becomes relevant since there is specific treatment and long-term complications, such as pulmonary hypertension and right heart failure, could be prevented.
