Descripción
Dilated cardiomyopathy is a form of heart disease in which the heart (cardiac) muscle becomes thin and enlarged (dilated). The dilation, which typically starts in the lower left chamber of the heart (left ventricle), makes it harder for the heart to pump blood to the rest of the body.
Dilated cardiomyopathy is called nonsyndromic dilated cardiomyopathy when it cannot be explained by other causes, such as a heart attack or damage to the valves of the heart, and is not associated with signs and symptoms that affect other parts of the body.
The signs and symptoms of nonsyndromic dilated cardiomyopathy vary among affected individuals, even among members of the same family. The signs and symptoms typically begin in mid-adulthood, but they can occur at any time from infancy to late adulthood. Affected individuals may have a sensation of fluttering or pounding in the chest (palpitations); shortness of breath, especially when lying down or during physical activity; fatigue; and swelling of the legs and feet. Affected individuals may also have episodes of dizziness or fainting (syncope).
Over time, people with nonsyndromic dilated cardiomyopathy may develop life-threatening complications, which can include abnormal heart rhythms (arrhythmias) and heart failure. Although uncommon, sudden death can occur in people with nonsyndromic dilated cardiomyopathy, even if they have no other symptoms of the condition.
