First of all, we must pay attention to rest. Adequate rest is the guarantee for the recovery of myocarditis. For ordinary myocarditis, we can recover after two to four weeks of rest. For slightly serious myocarditis, we can recover after a month to three months of rest. Of course, for more serious myocarditis, we may even need to rest for half a year. In terms of diet, we must pay attention to a diet of low salt, low fat, high-quality protein, high fiber, and appropriately eat more vegetables and fruits to supplement vitamin C and vitamin E. In addition, we must choose drugs according to the severity of the patient, anti-inflammatory and antiviral, improve the heart muscle, and nourish the metabolism of the heart muscle. If there is heart failure, we must actively treat it. Arrhythmias also need treatment and prevention. In case of acute heart failure, immediate cardiotonic diuretic treatment is required. In case of malignant arrhythmia, even high atrioventricular block, pacemaker implantation may be required at this time. Cardiogenic shock may occur, and vasoactive drugs must be used. Regular follow-up visits must be made.
