Treatment for cardiomyopathy varies, depending on what type of cardiomyopathy you have and how serious it is. Treatments can include:

• * Medications. Your doctor may prescribe medications that can improve your heart's pumping ability, such as ACE inhibitors or angiotensin II receptor blockers. Beta blockers, which make your heart beat more slowly and less forcefully, help reduce the strain on it.
• * Medical devices. If you have dilated cardiomyopathy, treatment may include a special pacemaker that coordinates the contractions between the left and right ventricles of your heart, improving the heart's pumping ability. If you're at risk of serious arrhythmias, an implantable cardioverter-defibrillator (ICD) may be an option. ICDs are small devices implanted in your chest to continuously monitor your heart rhythm and deliver electrical shocks when needed to control abnormal, rapid heartbeats. The devices can also work as pacemakers.
• * Heart transplant. If you have severe cardiomyopathy and medications can't control your symptoms, a heart transplant may be necessary.
