The uptake of family screening in hypertrophic cardiomyopathy and an online video intervention to facilitate family communication.

Background: Individuals with hypertrophic cardiomyopathy (HCM), even when asymptomatic, are at-risk for sudden cardiac death and stroke from arrhythmias, making it imperative to identify individuals affected by this familial disorder. Consensus guidelines recommend that first-degree relatives (FDRs) of a person with HCM undergo serial cardiovascular evaluations.

Methods: We determined the uptake of family screening in patients with HCM and developed an online video intervention to facilitate family communication and screening.
