Restrictive cardiomyopathy
Restrictive Cardiomyopathy
Restrictive cardiomyopathy (pronounced as re-stric-tive car-dio-my-op-a-thy) is a type of cardiomyopathy in which the walls of the heart become rigid, but not necessarily thickened, leading to restricted filling and reduced diastolic volume of either or both ventricles.
Etymology
The term "restrictive cardiomyopathy" is derived from the Latin word restrictus, meaning "drawn back, tightened" and the Greek words kardia, meaning "heart", and pathos, meaning "suffering".
Symptoms
Symptoms of restrictive cardiomyopathy may include fatigue, breathlessness (dyspnea), and edema (swelling) of the legs and feet. Other symptoms may include palpitations, dizziness, and fainting (syncope).
Causes
Restrictive cardiomyopathy can be caused by various conditions that make the heart less elastic, such as amyloidosis, sarcoidosis, hemochromatosis, and connective tissue disorders. It can also be idiopathic, meaning its cause is unknown.
Diagnosis
Diagnosis of restrictive cardiomyopathy typically involves echocardiography, cardiac MRI, and endomyocardial biopsy. Other tests may include electrocardiogram (ECG), chest X-ray, and cardiac catheterization.
Treatment
Treatment for restrictive cardiomyopathy aims to manage symptoms and slow the progression of the disease. This may involve medications, lifestyle changes, and in severe cases, heart transplant.
Prognosis
The prognosis for restrictive cardiomyopathy varies depending on the underlying cause and the severity of the disease. In some cases, it can lead to heart failure, arrhythmias, and thromboembolism.
