Prognostic role of NYHA class in heart failure patients undergoing primary prevention ICD therapy.

ABSTRACT:

Aims

Concerns about the prognostic value of NYHA functional class (FC) in heart failure (HF) patients carrying a prophylactic implantable cardioverter defibrillator (ICD) are still present. We aimed to compare whether mortality and arrhythmic risk were different, in a cohort of HF patients undergoing ICD-only implant, according to their FC.

Methods and results

HF patients with left ventricle ejection fraction (LVEF) ≤35%, undergoing first prophylactic ICD-only implant were collected from a multicentre nationwide registry (2006-2015). Six hundred and twenty-one patients were identified (101 patients in NYHA I; 411 in NYHA II; 109 in NYHA III). After a mean follow-up of 4.4 years (±2.1), 126 patients died (20.3%). All-cause mortality risk was higher in symptomatic patients: 13
