Cardiomyopathy is a disease in which your heart muscle weakens and has difficulty pumping blood. Read about its causes, risk factors, treatment, and more.


An electrocardiogram (ECG) is used to record your heart’s electrical activity and detect abnormal heart rhythms. Coronary angiography may be done with a heart catheterization. Heart catheterization involves inserting a long narrow tube through a blood vessel and into the heart to see how the heart and coronary arteries are working.


What Is the Treatment for a Weak Heart Muscle? Doctors recommend treatment according to the type of cardiomyopathy and the severity of the condition, explains Heartland Cardiovascular Center, LLC.

Cardiomyopathy refers to diseases of the heart muscle. In cardiomyopathy, the heart muscle becomes thick or rigid, which can weaken the heart. Learn more about causes, risk factors, screening and prevention, signs and symptoms, diagnoses, and treatments for cardiomyopathy, and how to participate in clinical trials.


In dilated cardiomyopathy, the heart muscle becomes weakened and is unable to contract normally. To compensate for this weakening, the heart muscle "stretches," causing the heart (especially the left ventricle) to dilate.So the hallmark of dilated cardiomyopathy is a weakened, enlarged heart.


Causes and Symptoms of a Weak Heart.

Heart attack is the number one killer in the United States of America and every year at least 500,000 new cases are diagnosed according to the Center for Disease Control. Some of the most common diseases are coronary artery disease (CAD), diabetes and high blood pressure.


Systolic Heart Failure — This is the most common cause of heart failure and occurs when the heart is weak and enlarged. The muscle of the left ventricle loses some of its ability to contract or shorten. In turn, it may not have the muscle power to pump the amount of oxygenated and nutrient-filled blood the body needs.


Dilated cardiomyopathy (also called idiopathic dilated cardiomyopathy) is a condition in which the heart becomes weak and the chambers get large. As a result, the heart cannot pump enough blood out to the body. It can be caused by many medical problems. Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick.
