Currently, myocardial injury has been reported in patients hospitalized with coronavirus disease 2019 (COVID-19). The studies also show a correlation between cardiac events and severe forms of the disease. COVID-19 begins with an early infection phase in which the virus infiltrates the lung parenchyma and proliferates. It then progresses to the pulmonary phase, where the initial inflammatory process, characterized by vasodilation, vascular permeability, and leukocyte recruitment, leads to lung damage, hypoxemia, and cardiovascular stress. The renin angiotensin aldosterone system is important in the pathophysiology of severe acute respiratory syndrome coronavirus 2 infection and in the propagation of systemic inflammation. Within this system, the pathway mediated by angiotensin-converting enzyme 2 (ACE2) produces vasodilation, cardioprotection, anti-oxidation, and anti-inflammation. Furthermore, the free form of ECA2 prevents binding of the virus to host cells and reduces its damage to the lung.
