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.
