Non-obstructive Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiomyopathy with a prevalence in the general population of 1:200. Among clinically recognized patients, HCM may be compatible with normal longevity. However, a subset of HCM patients remain at risk for several adverse disease related complications including sudden death, usually in the absence of symptoms, progressive heart failure symptoms and atrial fibrillation with risk of thromboembolic stroke. Initial evaluation of patients with HCM attempts to classify patients as either obstructive HCM or non-obstructive HCM.
