How is Hypertrophic Cardiomyopathy diagnosed?

  • Echocardiogram: This is commonly used to diagnose Hypertrophic Cardiomyopathy. Utilizes ultrasounds to see abnormally thickened heart muscle. It also examines heart chambers and valves.
  • Electrocardiogram: To measure electrical signals of the heart.
  • Cardiac MRI
  • Exercise test: Record’s EEG while treadmill or physical activity
  • Genetic testing for Hypertrophic Cardiomyopathy: To identify the gene mutation

How is Hypertrophic Cardiomyopathy treated?

Non-pharmacological treatment:

  • ICD (Implantable cardioverter-defibrillator)
  • Septal ablation (Catheter-based therapy)
  • Septal myectomy (Surgery based therapy)
  • A pacemaker in case of abnormal heartbeat

Pharmacological treatment:

  • Anticoagulants such as warfarin, rivaroxaban, dabigatran or apixaban in case of atrial fibrillation to prevent blood clots
  • CCB’s( Calcium channel blockers) such as verapamil or diltiazem
  • Beta-blockers such as metoprolol, propranolol or atenolol

Amiodarone or disopyramide to control over heart rhythm
