Cardiomyopathies are conditions where there is an intrinsic abnormality of heart muscle cellsresulting in heart muscle dysfunction, sometimes leading to abnormal heart rhythms and heart failure.

Types of cardiomyopathy

There are several different types of cardiomyopathy. The main types are hypertrophic cardiomyopathy(where the heart walls are much thicker than normal); dilated cardiomyopathy(where the chambers of the heart enlarge); arrhythmogenic right ventricular cardiomyopathy (where damaged heart muscle is gradually replaced by scar tissue and fat); and restrictive cardiomyopathy, where the heart muscle cannot relax properly between heartbeats.


the commonest symptoms are those of heart failure. Other possible symptoms include dizziness and chest pain.


this depends on which type of cardiomyopathy you have and how serious it is. The options include medications, pacemakers to prevent abnormal heart rhythms and sometimes heart surgery is required.
