I30-I52: Other forms of heart disease

I43: Cardiomyopathy in diseases classified elsewhere

Cardiomyopathy in diseases classified elsewhere is a group of heart diseases that develop as a secondary complication from another underlying health condition. These diseases weaken the heart muscle, making it harder for your heart to pump blood to the rest of your body. They can be caused or worsened by a wide variety of conditions such as various infections, vitamin deficiencies, metabolic disorders, alcohol abuse, or exposure to certain chemicals or medications. Common symptoms might include shortness of breath, swelling in the legs, ankles and feet, bloating, fatigue, and irregular heartbeats. These cardiomyopathies can progress differently depending on the person and the underlying disease causing the condition, with some people remaining stable for many years and others worsening rapidly. They primarily affect the cardiovascular system, particularly focusing on the heart's ability to pump effectively.
