Understanding Myocarditis & Pericardial Disease

What is Myocarditis?

Myocarditis is a condition where the heart muscle becomes inflamed, causing damage to the heart. The most common causes of myocarditis are viral infections, including the common cold, influenza, and hepatitis. Other causes include bacterial infections, fungi, parasites, and autoimmune diseases. Symptoms of myocarditis can include chest pain, fatigue, shortness of breath, and irregular heartbeats. To diagnose myocarditis, doctors will perform a physical examination, blood tests, electrocardiogram (ECG), echocardiogram, and cardiac MRI. A biopsy, which involves inserting a tube into a blood vessel in the neck to access the heart and obtain a small amount of heart tissue for analysis may be performed. Treatment options for myocarditis may include medications to reduce inflammation, rest, and lifestyle changes. In severe cases, hospitalization may be necessary.

What is Pericardial Disease?

Pericardial disease is a condition where the pericardium, the protective sac surrounding the heart, becomes inflamed or filled with fluid, causing pressure on the heart. Pericarditis is the most common form of pericardial disease, and it can be caused by viral infections, autoimmune diseases, or unknown factors. Symptoms of pericardial disease can include chest pain, shortness of breath, and a dry cough. Diagnosis of pericardial disease may involve blood tests, echocardiogram, and chest x-ray. Treatment options may include anti-inflammatory medications, rest, and lifestyle changes. In severe cases, drainage of fluid from the pericardium may be necessary.

Myocarditis vs. Pericardial Disease

While myocarditis and pericardial disease are both heart conditions that can cause inflammation, they differ in the part of the heart that is affected. Myocarditis affects the heart muscle, while pericardial disease affects the protective sac surrounding the heart. However, both conditions can have similar symptoms, such as chest pain and shortness of breath. Common causes and risk factors for both conditions include viral infections and autoimmune diseases.

Preventative Measures for Myocarditis & Pericardial Disease

While there is no way to prevent myocarditis or pericardial disease, individuals can reduce their risk of developing these conditions. Lifestyle changes such as exercising regularly, maintaining a healthy weight, and avoiding smoking can help to maintain health. Vaccinations can also prevent some viral and bacterial infections that may lead to myocarditis or pericardial disease.
