Dilated Cardiomyopathy (DCM) is
a disease of the heart muscle that causes the heart to expand, stretch,
and become thinner, making it difficult for the heart to pump blood adequately.
It typically involves the left ventricle but might eventually include all four
chambers. The pumping function is reduced, so the body receives less blood rich
in oxygen, and the risk of heart failure and other catastrophic conditions
increases.
Genetics, viral infections,
long-term high blood pressure, severe alcohol usage, certain drugs,
dietary deficits, or autoimmune illnesses can cause DCM. Occasionally
the cause is unknown, and the condition is called idiopathic dilated
cardiomyopathy.
Symptoms include weariness, shortness of breath, swelling of the legs and
ankles, chest pain, disorientation, and irregular heart rhythms. Diagnosis is
generally based on physical exam, electrocardiogram (ECG), echocardiography,
cardiac MRI, blood tests, and other imaging procedures to determine the
anatomy and function of the heart.
The purpose of treatment is
to enhance heart function, relieve symptoms, and prevent complications. They
may suggest medication, lifestyle changes, implanted devices like pacemakers
or defibrillators, or a heart transplant in severe circumstances. Early
diagnosis, good medical follow-up, and correct therapy can considerably
improve the quality of life and the long-term outcome of patients with Dilated
Cardiomyopathy.
