I30-I52: Other forms of heart disease

I41: Myocarditis in diseases classified elsewhere

Myocarditis refers to inflammation of the heart muscle, specifically due to diseases classified elsewhere or otherwise specified. When the heart muscle becomes inflamed, it can become weak or start to work abnormally, which can lead to symptoms such as shortness of breath, heart palpitations, swollen limbs, and fatigue. The cause of the inflammation often comes from infections or diseases impacting other parts of the body. For instance, viral infections like the influenza virus can spread to the heart and cause inflammation. Similarly, autoimmune diseases can also mistakenly damage healthy heart tissue, leading to myocarditis. This condition may occur suddenly or may progressively worsen over time, affecting both the cardiac and circulatory systems. Understanding the origin of the inflammation is crucial to performing the correct management of the condition.
