Introduction
Patients with myocarditis must avoid alcohol consumption, as alcohol directly damages myocardial cells, exacerbates myocardial inflammatory responses, increases heart rate, and elevates cardiac workload. Drinking alcohol during the active phase of the disease prolongs recovery time and raises the risk of arrhythmias and heart failure. If symptoms such as palpitations, chest tightness, fatigue, or shortness of breath occur, prompt medical evaluation is essential.

Patients with myocarditis must abstain from alcohol. Ethanol directly damages cardiomyocytes, exacerbates myocardial inflammatory responses, accelerates heart rate, and increases cardiac workload. Drinking alcohol during the active phase of illness prolongs recovery time and raises the risk of arrhythmias and heart failure. If symptoms such as palpitations, chest tightness, fatigue, or shortness of breath occur, prompt medical evaluation is essential.

Myocarditis is most commonly triggered by viral infection, resulting in inflammatory injury to the myocardium and reduced cardiac tolerance. Upon entering the body, alcohol causes vasodilation, increases heart rate, and elevates myocardial oxygen consumption—further compromising already damaged myocardial tissue. Following diagnosis, strict bed rest is required, along with medications aimed at nourishing the myocardium and controlling arrhythmias to mitigate myocardial inflammation.

During the recovery phase, the myocardium remains fragile; even brief alcohol exposure may trigger disease relapse. Moreover, alcohol impairs hepatic metabolism, interferes with drug absorption, and diminishes therapeutic efficacy. Throughout the entire treatment and convalescence period, all alcoholic beverages must be strictly avoided. Continuous monitoring of heart rate is recommended to reduce the likelihood of cardiac complications.

In daily life, ensure adequate sleep, minimize emotional fluctuations, consume high-quality protein and vitamin-rich foods, and gradually restore myocardial function. Maintain quiet rest until myocardial injury has fully healed.
