is a disease that affects the heart muscle and the way it pumps. There are different
types of cardiomyopathies. And these types have different causes. Cardiomyopathy may
occur as a result of damage to the heart, such as from a heart attack, or a person
may inherit the tendency to develop it.
There are many other types
of cardiomyopathy that can be classified by what causes the heart muscle problem.
For example, inflammation of the heart muscle can cause inflammatory cardiomyopathy.
A heart rhythm problem can cause tachycardia-induced cardiomyopathy. A stressful event
can cause takotsubo (stress) cardiomyopathy in which a heart chamber changes shape
and cannot pump blood normally.
some cardiomyopathies, the changes in the heart muscle can lead to other heart problems
such as heart failure. Heart failure means the heart cannot pump blood normally. When
the heart cannot pump blood well, the rest of the body may not get enough blood, oxygen,
or nutrients. Cardiomyopathy can also lead to other heart problems such as atrial
fibrillation, which is a type of irregular heartbeat.
How is it treated?
Treatment for cardiomyopathy depends on the type of cardiomyopathy
and the type of heart problems that occur as a result of the changes in the heart
muscle. Treatment typically includes medicine and healthy lifestyle changes.
