Restrictive cardiomyopathy is the least usual cardiomyopathy. It is called as such due to the fact that it limits the heart from extending and filling it with blood correctly. The firm walls of the chambers of the heart prevent them from properly filling even though the rhythmicity and contractility of the heart may be regular. That is why blood flow is decreased and the blood that usually enters the heart is backed up in the circulatory system. Over time, patients with restrictive cardiomyopathy acquire heart failure.
