Restrictive Cardiomyopathy

Restrictive Cardiomyopathy (RCM) is an uncommon form of heart muscle disease in which the walls of the heart become abnormally stiff while maintaining a near-normal thickness and pumping ability. Because the ventricles cannot relax properly between heartbeats, they fill with less blood, reducing the amount of blood delivered to the body. This condition may develop due to inherited genetic disorders or secondary causes such as amyloidosis, hemochromatosis, sarcoidosis, radiation therapy, or connective tissue diseases.

People with Restrictive Cardiomyopathy often experience fatigue, shortness of breath, reduced exercise tolerance, swelling in the legs or abdomen, and irregular heart rhythms. As the disease progresses, it may lead to heart failure, blood clots, or pulmonary hypertension if left untreated.

Diagnosis typically involves echocardiography, electrocardiography (ECG), cardiac MRI, blood tests, and, in selected cases, heart tissue biopsy to determine the underlying cause. Treatment focuses on managing symptoms, improving heart function, and addressing the condition responsible for the disease. Medications such as diuretics, antiarrhythmic drugs, and anticoagulants may be prescribed. In advanced cases where symptoms cannot be controlled, heart transplantation may be considered. Early diagnosis, ongoing monitoring, and specialized medical care can significantly improve quality of life and long-term outcomes.
