The impact of frailty in older patients with non-ischaemic cardiomyopathy after implantation of cardiac resynchronization therapy defibrillator.

Aims: Frailty status impacts the prognosis in older patients with heart disease. However, frailty status impact is unknown in patients with non-ischaemic cardiomyopathy after cardiac resynchronization therapy (CRT).

Methods And Results: Functional measures of baseline frailty and clinical data were collected for all patients with non-ischaemic cardiomyopathy before CRT defibrillator (CRT-D) implantation.
