Overview

Dilated Cardiomyopathy is a condition in which the heart chambers become enlarged and weakened. As the heart muscle stretches and thins, its ability to pump blood effectively decreases. The left ventricle is most commonly affected, though other chambers may also enlarge. This reduced pumping function can lead to heart failure over time. The condition may develop gradually and may initially produce mild symptoms. It can occur at any age and may affect individuals with or without prior heart disease. As the heart becomes less efficient, the body may not receive adequate blood supply. Fatigue and reduced exercise capacity are common. Early recognition is important to prevent further complications. Continuous monitoring is often required to assess heart function.

During this condition, the heart muscle fibers weaken and stretch. The chambers enlarge, making it harder for the heart to contract efficiently. As pumping strength decreases, blood may accumulate in the heart and lungs. This can cause shortness of breath and swelling in the legs. Over time, irregular heart rhythms may develop due to structural changes in the heart muscle.

Diagnosis

Diagnosis includes physical examination and assessment of symptoms. Echocardiography is commonly used to evaluate heart size and pumping function. Electrocardiogram (ECG) may detect rhythm abnormalities. Chest X-ray can show heart enlargement. In some cases, cardiac MRI or blood tests are performed to determine underlying causes.
