What Is Dilated Cardiomyopathy?Dilated cardiomyopathy (DCM) is a condition in which the heart's ability to pump blood is decreased because the heart's main pumping chamber, the left ventricle, is enlarged and weakened. In some cases, it prevents the heart from relaxing and filling with blood as it should. Over time, it can affect the other heart chambers. What Is the Treatment for DCM?Treatment of dilated cardiomyopathy is aimed at decreasing the heart size and the substances in the bloodstream that enlarge the heart and ultimately lead to worsened symptoms:Medications: To manage heart failure, most people improve by taking drugs, such as a beta-blocker, ACE inhibitor an ARB, and/or diuretics. If you have an arrhythmia (irregular heart beat), your doctor may give you a medication to control your heart rate or lessen the occurrence of arrhythmias. Blood thinners may be used to prevent blood clots from occurring.Lifestyle changes: If you have heart failure, sodium should be restricted to 2,000-3,000 mg per day -- for the rest of your life. Your doctor may recommend aerobic exercise, but don't do heavy weight lifting. What Surgeries Are Used to Treat DCM?People with severe DCM may need one of the following surgeries:
