Restricted cardiomyopathy

Restrictive cardiomyopathy is a rare type of primary cardiomyopathy. It is caused by endocardial and subendocardial fibrosis, which makes it difficult to stretch and restrict filling during diastole, and the diastolic function is severely impaired, while the systolic function remains normal. Or only mildly impaired cardiomyopathy. Among the three types of cardiomyopathy of unknown cause, restricted cardiomyopathy is far less common than dilated and hypertrophic. The disease mainly refers to endomyocardial fibrosis (EMF) that occurs in tropical regions and more common eosinophilic cardiomyopathy (Louml; fflerrsquo; s cardiomyopathy) in temperate regions. In recent years, clinical and experimental studies have shown that these two different types of diseases may be manifested at different stages of the same disease. The clinical manifestations of the early stages of the disease are different, but in the later stages of the disease, the clinical manifestations are general obstructive congestion The myocardial pathological changes are basically the same, so they are discussed in one place.
