Clinical Presentation and Therapy of Cardiomyopathies

Cardiomyopathies are a group of diseases that primarily affect the heart muscle, leading to mechanical or electrical dysfunction of the heart. They can be categorized into primary and secondary forms. Primary cardiomyopathies can be further classified as congenital, acquired, or mixed. In terms of the heart muscle itself, there are five distinct types of cardiomyopathies: hypertrophic cardiomyopathy, dilated or congestive cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic (right ventricular) dysplasia, and noncompaction cardiomyopathy. While cardiomyopathies primarily affect the heart, they can also have systemic manifestations, impacting other organs and potentially causing progressive debilitation, heart failure, or even death.
