Cardiomyopathy may be seen in all except ?

Ans. is 'd' i.e., Alkaptonuria o Cardiomyopathy, which literally means "hea muscle disease", is the deterioration of the function of the myocardium. o Cardiomyopathies can generally be categorized into two groups ? 1. Extrinsic cardiomyopathies o These are the cardiomyopathies where the primary pathology is outside the myocardium. o Most cardiomyopathies are extrinsic, because by for the most common cause of cardiomyopathy is ischemia, ischemic cardiomyopathy. o Other impoant extrinsic cardiomyopathies are alcoholic cardiomyopathy and diabetic cardiomyopathy. 2. Intrinsic cardiomyopathies o An intrinsic cardiomyopathy is weakness in the muscle of hea that is not due to an identifiable external cause. o Intrinsic cardiomyopathies are generally classified into three types. 1.Dilated cardiomyopathy --> Most common intrinsic cardiomyopathy. 2.Hyperophic cardiomyopathy 3.Restrictive cardiomyopathy Least common intrinsic cardiomyopathy.
