Dilated cardiomyopathy (DCM) is a condition in which the heart becomes enlarged and cannot pump blood effectively.[3] Symptoms vary from none to feeling tired, leg swelling, and shortness of breath.[2] It may also result in chest pain or fainting.[2] Complications can include heart failure, heart valve disease, or an irregular heartbeat.[3][4]
Causes include genetics, alcohol, cocaine, certain toxins, complications of pregnancy, and certain infections.[8][9] Coronary artery disease and high blood pressure may play a role, but are not the primary cause.[5][8] In many cases the cause remains unclear.[8] It is a type of cardiomyopathy, a group of diseases that primarily affects the heart muscle.[3] The diagnosis may be supported by an electrocardiogram, chest X-ray, or echocardiogram.[9]
In those with heart failure, treatment may include medications in the ACE inhibitor, beta blocker, and diuretic families.[9] A low salt diet may also be helpful.[5] In those with certain types of irregular heartbeat, blood thinners or an implantable cardioverter defibrillator may be recommended. Cardiac resynchronization therapy (CRT) may be necessary.[9] If other measures are not effective a heart transplant may be an option in some.[9]
About 1 per 2,500 people is affected.[9] It occurs more frequently in men than women.[10] Onset is most often in middle age.[5] Five-year survival rate is about 50%.[9] It can also occur in children and is the most common type of cardiomyopathy in this age group.[9]

Tachycardia-induced cardiomyopathy is a reversible cause of heart failure and dilated cardiomyopathy. Tachycardia-induced cardiomyopathy should be considered in all patients with a dilated cardiomyopathy of uncertain origin and who have tachycardia or atrial fibrillation with a fast ventricular rate.
