I30-I52: Other forms of heart disease

I52: Other heart disorders in diseases classified elsewhere

The category "Other heart disorders in diseases classified elsewhere" encompasses a range of heart conditions that occur as complications or secondary manifestations of other diseases. Heart diseases found in this group are usually the result of systemic illnesses that may adversely affect the heart, leading to structural changes, abnormal heart rhythms, or impaired heart function. The cause of these heart disorders can be infections, hormonal imbalances, autoimmune diseases, and other systemic conditions. Common symptoms may include shortness of breath, fatigue, irregular heartbeats, swelling in the legs or abdomen, and chest pain. As the disorders evolve, the effects could progress from mild, barely noticeable symptoms to severe heart disease. These conditions often influence multiple body systems, but the cardiovascular system is particularly affected due to the role of the heart in circulation and oxygenation of the body. Note that presenting symptoms and progression could significantly change based on the underlying disorder causing the heart condition.
