ComplicationsBy Mayo Clinic Staff
Complications from dilated cardiomyopathy include:
April 28, 2017
- Heart failure. Poor blood flow from the left ventricle can lead to heart failure.
- Heart valve regurgitation. Enlargement of the left ventricle may make it harder for your heart valves to close, causing a backward flow of blood and making your heart pump less effectively.
- Fluid buildup (edema). Fluid can build up in the lungs, abdomen, legs and feet (edema).
- Abnormal heart rhythm (arrhythmia). Changes in heart structure and changes in pressure on the heart's chambers can contribute to arrhythmias.
- Sudden cardiac arrest. Dilated cardiomyopathy can cause your heart to suddenly stop beating.
- Blood clots (emboli). Pooling of blood (stasis) in the left ventricle can lead to blood clots, which may enter the bloodstream, cut off the blood supply to vital organs, and cause stroke, heart attack or damage to other organs. Arrythmias can also cause blood clots.
