Treatments and drugs

By Mayo Clinic Staff

The goal of treatment is to relieve symptoms and prevent sudden cardiac death in people at high risk. Specific treatment varies depending on the severity of your symptoms.

The options include:

  • Medication to relax the heart muscle and to slow the heartbeat rate so that the heart can pump more efficiently. Your doctor may recommend beta blockers, the calcium channel blockers verapamil or diltiazem, or the sodium blocker disopyramide (Norpace).
  • Septal myectomy, an open-heart procedure in which the surgeon removes part of the thickened, overgrown septum between the ventricles. Removing part of this overgrown muscle improves blood flow and reduces mitral regurgitation. Myectomy may be recommended if medications don't relieve symptoms. Most people who have myectomy have no further symptoms. Septal myectomy is available only in medical centers that specialize in the treatment of HCM.
  • Septal ablation in which a small portion of the thickened heart muscle is destroyed by injecting alcohol through a catheter into the artery supplying blood to that area. Possible complications with this procedure include heart block — a disruption of the heart's electrical system — which requires implantation of a pacemaker.
  • Implantable cardioverter-defibrillator (ICD), a pager-sized device implanted in your chest like a pacemaker. An ICD continuously monitors your heartbeat. If a life-threatening arrhythmia occurs, the ICD delivers precisely calibrated electrical shocks to restore a normal heart rhythm. ICD may be recommended for people with hypertrophic cardiomyopathy who are at high risk of sudden cardiac death because of abnormal heart rhythms.
