Dilated Cardiomyopathy (DCM) is a heart condition where the left ventricle enlarges and weakens, reducing the heart’s ability to pump blood efficiently. Common symptoms include fatigue, shortness of breath, swelling in legs or feet, and irregular heartbeats. Causes may include genetics, infections, alcohol abuse, or other heart conditions. Treatment involves medications, lifestyle changes, and in severe cases, surgical interventions or devices. Early diagnosis and proper management can improve heart function and enhance quality of life.
