Hypertrophic cardiomyopathy is a congenital or acquired disorder characterized by marked ventricular hypertrophy with diastolic dysfunction (eg, due to valvular aortic stenosis, coarctation of the aorta, systemic hypertension). Hypertrophic cardiomyopathy (HCM) is an inherited disease of the cardiac sarcomere that results in left ventricular hypertrophy, hyperdynamic function, microvascular dysfunction, impaired relaxation, and myocardial fibrosis.1 Clinical hallmarks include left ventricular outflow tract obstruction (LVOTO), arrhythmias, and heart failure.2,3 To date, no disease-modifying therapies have been identified, although clinical trials of novel therapeutics are in progress.4,5 This analysis focuses on HCM management strategies fundamental to the care of patients with HCM: LVOTO, sudden cardiac death (SCD), atrial fibrillation, exercise restriction, and heart failure. You may need to take antibiotic medications and take other precautions to reduce the risk of bacterial endocarditis, a potentially life-threatening condition.

ICDs can help people at risk for life-threatening arrhythmias or sudden cardiac death. This heart problem often shows up during the teen years, but it can start at other ages. The ventricle can also become very stiff. Primary prevention with an ICD is reasonable for patients with severe hypertrophy (>30mm), family history of sudden death in a first degree relative, recent unexplained syncope, or "burnt-out" HCM (LVEF < 50%).2,6,7 The presence of non-sustained ventricular tachycardia on 24-hour Holter or abnormal blood pressure response to exercise, when added to other risk factors, also supports primary prevention ICD.14 Other risk factors that may influence the decision to place an ICD for primary prevention include marked late-gadolinium enhancement on magnetic resonance imaging (MRI) (>15%), the presence of an apical aneurysm, and some genetic mutations present in families with high prevalence of sudden cardiac death.3,6,7,15-17 Secondary prevention with ICD placement in those surviving SCD or with sustained ventricular tachycardia (VT) is universally recommended.6 In the case of syncope, a thorough evaluation for provoked obstruction is first required to avoid ICD implantation for syncope related to LVOTO rather than ventricular arrhythmias.7 Periodic reassessment of risk factors is recommended as part of ongoing follow up, with more frequent testing reserved for younger patients and those with borderline risk factors. If they hear a swishing or whooshing sound called a murmur, that could mean there is problem with blood flow through the heart which may suggest HCM.

Treatment of obstruction is indicated for symptomatic patients (NYHA Class > II) and medical therapy is the first-line approach.6 Importantly, patients may become accustomed to their reduced functional capacity and minimize symptoms,7 making objective confirmation of functional capacity with cardiopulmonary exercise testing a useful adjunct to history-taking for assessment of exertional intolerance.8,9 Medical therapies include beta-blockade and verapamil alone or in combination, though verapamil may increase LVOTO-associated symptoms in some individuals due to its vasodilatory effect.10 Disopyramide may be added for patients with symptoms refractory to the use of beta-blocker or calcium channel blocker therapy.10.
