Introduction: Atrial fibrillation (AF) adversely affect the outcomes in the patients of heart failure (HF) with reduced ejection fraction, however there are limited data exploring such an association in HF with preserved ejection fraction (HFpEF). Hypothesis: AF is associated with worse outcomes in HFpEF. Methods: We included all the patients with the primary diagnosis of HFpEF from the national inpatient sample (NIS) database (2012-2014) using ICD-9 codes. Exposure of interest was AF. Primary outcome was in-hospital mortality and secondary outcomes were rates of sudden cardiac arrest (SCA), syncope, cardiogenic shock, embolic stroke, acute myocardial infarction (AMI), acute kidney injury (AKI), passive hepatic congestion, ventricular fibrillation (V fib) and flutter, ventricular assist device (VAD), AICD, cardiac resynchronization therapy (CRT), intra-aortic balloon placement (IABP) placement and heart transplantation. Hospitalization cost was also studied. Results: Our study cohorts included 26,51,970 patients of HFpEF with AF and 37,44,101 patients of HFpEF without AF. AF cohort had more numbers of older patients and less female representation. In-hospital mortality was more in AF cohort. Similarly, the odds of SCA, cardiogenic shock, embolic stroke, passive hepatic congestion, Vfib and flutter, AICD and CRT placement were higher in AF cohort. The odds of syncope, AMI and AKI were lower in AF cohort as compared to non-AF cohort. While the odds of heart transplantation and VAD and IABP use remained comparable between the study cohorts, AF cohort incurred greater of cost of hospitalization. Conclusion: AF in HFpEF patients is associated with increased in-hospital mortality and cardiogenic shock and should be aggressively treated for improved outcomes.

Introduction: There is a lack of research comparing outcomes of Surgical Ablation (SA) and Catheter Ablation (CA) among Atrial Fibrillation(AF) patients with heart failure with Preserved Ejection Fraction (HFpEF) and . Hypothesis: The main objective is to compare short-term clinical outcomes of SA and CA in AF patients with HFpEF. Methods: We used the national inpatient sample to identify patients over 18 years with HFpEF hospitalization and AF, and undergoing SA and CA from 2016 - 2017. The clinical outcomes of SA versus CA in AF stratified as non-paroxysmal and paroxysmal were analyzed. Results: 1,530 HFpEF hospitalizations with AF who underwent SA and 1,045 HFpEF hospitalizations with AF who underwent CA were included in the analysis. Patients undergoing CA had higher baseline comorbidity. The in-hospital mortality between HFpEF with AF undergoing SA as compared to CA was similar (1.9% versus 1.4%, adjusted P-value 0.04). Patients undergoing SA had a significantly longer length of hospital stay, a higher percentage of post-procedural, and cardiac complications. In HFpEF patients with non-paroxysmal AF, SA as opposed to CA was associated with a higher percentage of in-hospital mortality (2.7% versus 0%, adjusted P-value=0.23), a longer length of stay, a higher cost of treatment, and a higher percentage of cardiac complications. Conclusions: In conclusion, CA is associated with lower in-hospital outcomes as compared to SA among AF with HFpEF patients. Further research with freedom from AF is needed between this group with long-term out c omes.

Abstract Background Catheter ablation improves clinical outcomes in symptomatic atrial fibrillation (AF) patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, the role of catheter ablation in HF patients with a preserved ejection fraction (HFpEF) is less clear. Purpose To determine the efficacy of catheter ablation of AF in patients with HFpEF relative to those with HFrEF. Methods We performed an extensive literature search and systematic review of studies that compared AF recurrence at one year after catheter ablation of AF in patients with HFpEF versus those with HFrEF. Risk ratio (RR) 95% confidence intervals were measured using the Mantel-Haenszel method for dichotomous variables, where a RR<1.0 favors the HFpEF group. Results Four studies with a total of 563 patients were included, of which 312 had HFpEF and 251 had HFrEF. All patients included were undergoing first time catheter ablation of AF. Patients with HFpEF experienced similar recurrence of AF one year after ablation on or off antiarrhythmic drugs compared to those with HFrEF (RR 0.87; 95% CI 0.69–1.10, p=0.24), as shown in Figure 1. Recurrence of AF was assessed with electrocardiography, Holter monitoring, and/or event monitoring at scheduled follow-up visits and final follow-up. Conclusion Based on the results of this meta-analysis, catheter ablation of AF in patients with HFpEF appears as efficacious in maintaining sinus rhythm as in those with HFrEF.

Background: Catheter ablation (CA) for atrial fibrillation (AF) has been proposed as a means of improving outcomes among patients with heart failure and reduced ejection fraction (HFrEF) who are otherwise receiving appropriate treatment. Unlike HFrEF, treatment options are more limited in patients with preserved ejection fraction (HFpEF) and the data pertaining to the management of AF in these patients are controversial. The aim of this systematic review and meta-analysis was to investigate the effects of CA on outcomes of patients with AF and HFpEF, such as functional status, post-procedural complications, hospitalization, morbidity and mortality, based on data from observational studies. Methods: We systematically searched the electronic databases MEDLINE, PUBMED, EMBASE and the Cochrane Library for Central Register of Clinical Trials until May 2020. Results: Overall, the pooling of our data showed that sinus rhythm was achieved long-term in 58.0% (95% CI 0.44–0.71). Long-term AF recurrence was noticed in 22.3% of patients. Admission for HF occurred in 6.2% (95% CI 0.04–0.09) whilst all-cause mortality was identified in 6.3% (95% CI 0.02–0.13). Conclusion: This meta-analysis is the first to focus on determining the benefits of a rhythm control strategy for patients with AF and HFpEF using CA, suggesting it may be worthwhile to investigate the effects of a CA rhythm control strategy as the default treatment of AF in HFpEF patients in randomized trials.

BACKGROUND The recent Heart Failure Association (HFA) of the European Society of Cardiology (ESC) consensus guidelines on diagnosis of heart failure with preserved ejection fraction (HFpEF) have developed a simple diagnostic algorithm for clinical use. PURPOSE To assess whether echocardiogram (echo) parameters needed to assess diastolic function are routinely collected in patients referred for assessment of heart failure symptoms. METHODS Retrospective analysis of echo referrals in January 2020 were assessed for parameters of diastolic function as per step 2 of the HF-PEFF diagnostic algorithm.  Echo images and clinical reports were reviewed. Electronic records were utilised to obtain clinical history, blood results (NT-proBNP) and demographic data. RESULTS 1330 patients underwent an echo in our department during January 2020. 83 patients were referred with symptoms of heart failure without prior history of cardiac disease; 20 patients found to have impaired left ventricular (LV) function were excluded from analysis. Of the 63 patients with possible HFpEF, HF-PEFF score was low in 18, intermediate in 33 and high in 12. Median age was 68 years (range 32 to 97 years); 25% had a BMI >30. There was a high prevalence of hypertension (52%), diabetes (19%) and atrial fibrillation (40%) (cf. Table 1). Body surface area (BSA) was documented in 65% of echo reports. Most echo parameters were recorded with the exception of global longitudinal strain (GLS) and indexed LV mass (cf. image 1). NT-proBNP was recorded in only 20 patients (31.7%). 12 patients with an intermediate HF-PEFF score could have been re-categorised to a high score depending on GLS and NT-proBNP (which were not recorded). CONCLUSION More than three quarters of echoes acquired in our department obtained the relevant parameters to assess diastolic function. The addition of BSA, and inclusion of NT-proBNP, and GLS would have been additive to a third of ‘intermediate’ patients to determine definite HFpEF. Our study demonstrates that the current HFA-ESC diagnostic algorithm and HF-PEFF scoring system are easy to use, highly relevant and applicable to current clinical practice.
