ACE2 and myocarditis: As a cardiotropic virus, SARS-CoV-2 significantly impacts myocardial tissue and the cardiac conduction system, causing myocarditis by binding to ACE2 (Angiotensin-Converting Enzyme 2) receptors expressed in myocardial cells, pericytes, and pneumocytes, leading to direct cellular damage and uncontrolled inflammatory responses [27].
