I42: Cardiomyopathy

I42.8: Other cardiomyopathies

"Other cardiomyopathies," classified under the ICD-10 code I42.8, refer to diseases of the heart muscle that do not fall under the common categories of cardiomyopathy. These conditions result in the heart becoming enlarged, thick, or rigid. In advanced stages, the heart may fail to pump blood efficiently leading to heart failure. They may be caused by various reasons including long-standing high blood pressure, heart tissue damage from a heart attack, chronic rapid heart rate, or metabolic disorders. Common symptoms include breathlessness with exertion or even at rest, swelling of the legs, ankles, and feet, bloating of the abdomen with fluid, fatigue, irregular heartbeats, and dizziness, fainting. Over time, cardiomyopathies can lead to complications such as heart failure or arrhythmias. It's important to note that symptoms can vary widely, from none at all to severe, depending on the type and severity of the cardiomyopathy.
