Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which part of the heart is affected by cardiomyopathy?

A	The Myocardium
B	The Arteries
C	The Ventricles
D	The Auricles

Explanation:

Detailed explanation-1: -It mostly affects the muscle of the heart’s main pumping chamber (left ventricle). Hypertrophic cardiomyopathy can develop at any age, but the condition tends to be more severe if it occurs during childhood.

Detailed explanation-2: -Obstructive: The most common type, hypertrophic obstructive cardiomyopathy (HOCM) means the wall (septum) between the left ventricle and right ventricle thickens. This can block (obstruct) blood flow from the left ventricle to the aorta (the body’s main artery).

Detailed explanation-3: -Arrhythmogenic right ventricular dysplasia (ARVD) or cardiomyopathy (ARVC) is caused by several genetic defects, affecting desmosomes, which are proteins on the surface of heart muscle cells that link those cells together. These genetic defects lead to abnormalities in the lower heart chambers, the ventricles.
