Cold can cause myocarditis because it is a series of clinical manifestations caused by viral infection, such as runny nose, sneezing, cough, sore throat and generalized aches and pains, and some patients may also have a low-grade fever. In this case, the virus invades the myocardial cells and causes degeneration, necrosis or cell lysis and replication in the myocardial cells, thus causing myocardial damage. Myocarditis caused by the common cold is mainly caused by various viruses, such as intestinal coxsackievirus, influenza virus and rhinovirus, as well as rabies virus, which can cause myocardial damage. Viral myocarditis is a series of non-specific infectious inflammation of the heart muscle. If you experience panic, chest tightness, palpitations and chest pain after a cold, you must go to the hospital to find out if there are any manifestations of myocardial damage through your doctor.
