Persistent atrial fibrillation in heart failure with preserved ejection fraction: Prognostic relevance and association with clinical, imaging and invasive haemodynamic parameters

Abstract

Sixty percent of our HFpEF patients suffered from AF. Persistent but not paroxysmal AF was strongly associated with event-free survival and was independently related to NYHA functional class, serum NT-proBNP, atrial size, cardiac ouput and presence of COPD.
