I30-I52: Other forms of heart disease
I42: Cardiomyopathy
Cardiomyopathy refers to a group of conditions where the heart muscle becomes enlarged, thick, or rigid. In some cases, the tissue in the heart may be scarred, leading to progressive conditions. As the condition worsens, the heart becomes gradually weaker and is less able to pump blood effectively, which could lead to heart failure or irregular heartbeats, known as arrhythmias. Causes can vary widely and may include long-term high blood pressure, heart tissue damage from a heart attack, chronic rapid heart rate, metabolic disorders, certain infections, and some chemotherapy drugs and radiation therapies for cancer. Symptoms often include breathlessness, swelling of the legs, ankles, and feet, bloating of the abdomen due to fluid build-up, fatigue, irregular heartbeats, dizziness, light-headedness, and fainting.
