Types of Cardiomyopathy
The different types of cardiomyopathy can differ, especially in the type of damage caused and its location.
Although most experts are unsure about the exact cause of cardiomyopathy, many claim that it can arise due to genetics or even, intense stress. It may also result from another related condition.
There are also certain studies that are looking into how cardiompathy can affect men more severely.
The types of cardiomyopathy are as follows:
Dilated Cardiomyopathy (DCM)
Dilated cardiomyopathy or DCM is the most prevalent type of cardiomyopathy. It usually starts in the left ventricle, which is the part of the heart in charge of pumping blood throughout the body.
The cardiac muscle in the left ventricle thins out, making the heart chamber bigger.
Eventually, cardiac muscle in the left ventricle as well as the atria will also start to expand. The gradual thinning of the cardiac muscles can weaken the heart.
Hypertrophic cardiomyopathy (HCM) causes the myocardium, or heart muscles, to thicken and enlarge.
This usually affects the septum (the wall separating the two bottom chambers of the heart), the ventricles, and the lower chambers of the heart.
There are two types of HCM, namely:
- Obstructive Hypertrophic Cardiomyopathy: The thickened cardiac muscle can lead to difficulties in pumping blood, and may even keep blood from flowing out of the heart.
- Non-obstructive Hypertrophic Cardiomyopathy: In some cases, there is no blockage that keeps blood from flowing out. But in non-obstructive HCM, the walls of the heart can harden. This can lead to an undersupply of blood.
