Relatives at 'substantial' risk of familial idiopathic dilated cardiomyopathy

Broader clinical and genetic testing might be warranted to pre-empt the disease, researchers suggest

Family members of patients with idiopathic dilated cardiomyopathy have a "substantial" one-in-five risk of developing the condition, supporting a role for wider screening, researchers say.

Early identification in at-risk family members could provide the opportunity to initiate treatment early but accurate recent estimates of the prevalence of familial dilated cardiomyopathy (DCM) have been lacking, the US team says.

They conducted a cross-sectional study of 1220 patients with DCM, defined as
