Atrial Fibrillation Ablation in Heart Failure: Difference in 3-Year Outcomes between Reduced and Preserved Ejection Fraction

HeartRhythm

The coexistence of these conditions can further induce structural changes and result in worsened outcomes such as stroke, HF decompensation, poorly controlled AF, and mortality [1]. However, the real-world data on the impact of AF ablation in heart failure with preserved ejection fraction (HFpEF) is not well-established.

Obesity in heart failure with preserved ejection fraction: Insights from the REDUCE LAP?HF II trial

European Journal of Heart Failure

Increasing severity of obesity is associated with multiple characteristics that may contribute to the development or worsening of heart failure (HF) with preserved ejection fraction (HFpEF).

Is sinus rhythm maintenance after repeat catheter ablation effective in patients with atrial fibrillation and heart failure with preserved ejection fraction?

Journal of Cardiovascular Electrophysiology

Abstract Background Heart failure (HF) with preserved ejection fraction (HFpEF) and atrial fibrillation (AF) are associated with high morbidity and mortality. HFpEF were defined as HFA-PEFF score of 5 or 6 and left ventricular ejection fraction 50% before the initial CA. 423 by a log-rank test).

Implications of tricuspid regurgitation and right ventricular volume overload in patients with heart failure with preserved ejection fraction

European Journal of Heart Failure

Abstract Aims The aim of this study was to assess the pathophysiological implications of severe tricuspid regurgitation (TR) in patients with heart failure with preserved ejection fraction (HFpEF) by using tricuspid transcatheter edge-to-edge repair (T-TEER) as a model of right ventricular (RV) volume overload relief.

Atrial fibrillation and risk of adverse outcomes in heart failure with reduced, mildly reduced, and preserved ejection fraction: A systematic review and meta?analysis

Journal of Cardiovascular Electrophysiology

Contemporary classification of HF categorizes it into HF with reduced ejection fraction (HFrEF), HF with mildly reduced ejection fraction (HFmrEF), and HF with preserved ejection fraction (HFpEF). Aggregate data comparing the risk profile of AF between these three HF categories are lacking.

Both HFpEF and HFmrEF Should be Included in Calculating CHA2DS2–VASc score: a Taiwanese Longitudinal Cohort

HeartRhythm

Congestive heart failure (CHF) as a risk of stroke in AF patients mainly referred to patients with left ventricular systolic dysfunction (HFrEF). Whether this should include patients with preserved ejection fraction (HFpEF) is debatable.

Clinical relevance of aortic conduit and reservoir function

Open Heart

Methods Twenty healthy controls (10 young and 10 age-gender-matched old controls) and 20 patients with heart failure with preserved ejection fraction (HFpEF) were recruited. Aortic reservoir function was defined as descending aortic diastolic stroke volume (DAo SV d ). All had 4D flow CMR.
