Transcript

  • 1. Hypertrophic Cardiomyopathy (HCM) Presented by Maffie Rafferty
  • 2. Description
    • Hypertrophied and stiff myocardium
      • Interventricular septum
      • Wall of left ventricle
    • Small left ventricular cavity
    • Myofibrillar disarray
    • Diastolic dysfunction
    • Coronary arteries may be compromised
    • Mitral valve regurgitation
  • 3. Other names/types of HCM
    • Asymmetric septal hypertrophy
    • Idiopathic hypertrophic subaortic stenosis
    • Muscular subaortic stenosis
    • Hypertrophic obstructive cardiomyopathy
    • Nonobstructive HCM
    • Athletic heart muscle disease
  • 4. Etiology
    • Not known
    • Congenital
      • Inherited
      • Abnormal gene
    • Acquired
      • Acromegaly
      • Pheochromocytoma
      • Part of aging
      • High blood pressure
    • Neurofibromatosis
  • 5. Signs and Symptoms
    • Asymptomatic/minor
    • Lightheadedness
    • Dizziness
    • Clinical manifestations
      • Angina pectoris
      • Syncope
      • Palpitations
      • Dyspnea on exertion
      • Sudden cardiac death caused by arrhythmias
  • 6. Signs and Symptoms (continued)
    • Signs of raised pulmonary venous pressure rare until terminal phase
      • Jugular venous distention
      • Ascites*
      • Ankle edema*
      • Pleural effusion
    • Pulmonary edema
    • * also signs of heart failure
  • 7. Diagnostic Procedures
    • Physical exam
      • Auscultation (murmurs, atrial gallop)
      • Carotid pulse
      • Palpation
      • Check legs for fluid buildup
    • ECG
    • Echo
    • Cardiac catheterization
    • Radionuclide angiography
  • 8. Diagnostic Procedures (continued)
    • Chest X-ray
    • Holter monitor
    • MRI of the heart
    • Blood tests
    • Exercise stress test
    • Biopsy
    • CT scan
  • 9. Treatment
    • None
    • Medicines
      • Beta-blockers – propanolol (Inderal), atenolol (Tenormin)
      • Calcium channel blockers – verapamil (Calan, Isoptin)
      • Antiarrhythmics – disopyramide (Norpace), amiodarone (Cordarone)
      • Anticoagulants
  • 10. Treatment (continued)
    • Septal myectomy
    • Alcohol septal ablation
    • Pacemaker
    • Mitral valve replacement
    • Implantable cardioverter-defibrillator (ICD)
    • Heart transplant
  • 11. Prognosis

  • 12. Prevention
    • HCM cannot be prevented
    • Preventing sudden death
      • Screen close blood relatives
