Hypertrophic cardiomyopathy (HCM), which was first described in 1958, occurs in approximately one in 500 people. Patients with HCM are at an increased risk of atrial fibrillation, which is not only poorly tolerated in this population, but also increases their risk of an embolic event. The incidence of stroke in HCM patients with atrial fibrillation is approximately 21-23%. ⋯ This therapy should be used without regard to other risk factors for stroke that may be present. Anticoagulation with the new oral anticoagulants may be considered as an alternative; although, specific data for patients with HCM is not available. The purpose of this review is to remind practitioners of the importance of stroke prophylaxis with oral anticoagulants in this population.
