The rare cardiac disorder known as restrictive cardiomyopathy (RCM) causes the heart's walls to stiffen and lose their elasticity, therefore impairing the heart's capacity to fill appropriately. Unlike other types of cardiomyopathy, the heart chambers do not grow noticeably; however, their compromised performance can cause heart failure and problems including arrhythmias.
Underlying diseases such as amyloidosis, sarcoidosis, hemochromatosis, or connective tissue disorders can all cause RCM. Occasionally the precise origin stays unknown. Although it can afflict anyone of any age, the disorder is more common in elderly individuals.
Shortness of breath, tiredness, leg and abdomen swelling, irregular heartbeats, and dizziness define RCM symptoms. The condition might cause fluid accumulation in the body and aggravation of heart failure as it advances.
To evaluate heart function, diagnosis calls for imaging studies including echocardiography, cardiac MRI, and electrocardiograms (ECGs). A biopsy may uncover the underlying cause in certain situations.
Treatment mostly aims to control symptoms and enhance cardiac performance. Medications include diuretics and blood thinners, which could help; severe cases might call for heart transplantation. Effective management of RCM depends mostly on changes in lifestyle and close observation.
