The difference between dilated cardiomyopathy and restrictive cardiomyopathy
The differences between dilated cardiomyopathy and restrictive cardiomyopathy mainly consist of the following two aspects: First, the anatomical differences: dilated cardiomyopathy is characterized by an enlargement of the heart, especially the left ventricle. Whereas restrictive cardiomyopathy is characterized by anatomical features such as narrowed or reduced heart cavities and limited ventricular filling. Second, the differences in symptoms: the symptoms of dilated cardiomyopathy are mainly characterized by those of left heart failure, such as exertional dyspnea, nocturnal paroxysmal dyspnea, and orthopnea. The main symptoms of restrictive cardiomyopathy, however, are manifestations of right heart failure, which commonly include nausea, abdominal distension, and peripheral edema.
