Background: In heart failure (HF) with sinus rhythm, resting and exercise heart rates correlate with exercise capacity and mortality. However, in HF with atrial fibrillation (AF), this correlation is unknown. Our aim is to investigate the association of resting and exercise ventricular rates (VRs) with exercise capacity and mortality in HF with AF. Methods: We identified 903 patients with HF and AF referred for cardiopulmonary stress testing. AF was defined as history of AF and AF during cardiopulmonary stress testing. We constructed multivariable models to evaluate the association of resting VR, peak exercise VR, VR reserve (peak VR−resting VR), and chronotropic index with (1) peak oxygen consumption (PVO 2 ) ≤18 mL/kg per minute, (2) continuous PVO 2 , and (3) 10-year all-cause mortality. Results: Median (25th–75th percentile) age was 60 (52–67) years, left ventricular ejection fraction was 25 (15–50)%, and 76.1% were males. Patients with lower (quartile 1) compared with higher (quartile 4) peak VR, VR reserve, and chronotropic index were more likely to have PVO 2 ≤18 mL/kg per min (adjusted odds ratio [95% CI]: 14.92 [8.07–27.58], 24.60 [12.36–48.98], and 22.31 [11.24–44.27], respectively), and higher all-cause mortality (adjusted hazard ratio [95% CI]: 2.56 [1.62–4.04], 2.29 [1.47–3.59], and 2.30 [1.51–3.49], respectively). For every 10 beats per minute increase in VR reserve, PVO 2 increased by 1.05 mL/kg per minute (B-coefficient [95% CI]: 1.05 [0.94–1.15]) and mortality decreased by 12% (adjusted hazard ratio [95% CI]: 0.88 [0.83–0.94]). Resting VR was associated with PVO 2 (B-coefficient [95% CI]: −0.46 [−0.70 to −0.23]) but not mortality (adjusted hazard ratio [95% CI]: 0.97 [0.88–1.06]). Conclusions: In patients with HF and AF, higher resting VR and lower peak exercise VR, VR reserve, and chronotropic index were all associated with worse peak exercise capacity, but only lower exercise VR parameters were associated with higher mortality. Dedicated studies are needed to gauge whether modulating exercise VR enhances exercise performance and outcomes.

10057 Background: Cardiac autonomic dysfunction (AD) has been associated with increased cardiovascular (CV) and all-cause mortality in several diseases. We evaluated the prevalence, functional and prognostic significance of cardiac AD in a cohort of breast cancer (BC) survivors referred for exercise treadmill testing (ETT). Methods: Cardiac AD was defined as the presence of both an elevated resting heart rate (HR ≥ 80 beats per minute) and abnormal HR recovery (HRR ≤ 12 beats per minute if active cool down, or ≤ 18 beats per minute if passive recovery) at 1 minute after peak exercise. Presence of cardiac AD, exercise capacity, and all-cause mortality were assessed in 448 women (age 62.6±10.0 years), 8.7 [range 4.5, 14.3] years from BC diagnosis, compared to 448 cancer-free, age- and sex-matched controls, all of whom were clinically referred for ETT. Results: Elevated resting HR (23.7% vs. 17.0%, p = 0.013), abnormal HRR (25.9% vs. 20.3%, p = 0.048), and cardiac AD (8.0% vs. 4.2%, p = 0.025) were more prevalent in BC survivors than controls. BC survivors with cardiac AD had reduced exercise capacity compared to those without AD (Table). Among controls, cardiac AD was not associated with decreased exercise capacity. Among BC survivors (age-adjusted hazard ratio 1.90 (95% CI 0.78-4.62) and controls (age-adjusted hazard ratio 4.09 (95% CI 0.49-34.18), cardiac AD was not associated with increased all-cause mortality. Conclusions: Among patients referred for ETT, BC survivors have an increased prevalence of cardiac AD relative to controls. Cardiac AD is associated with decreased exercise capacity, but not increased all-cause mortality, in BC survivors. Available strategies to modulate cardiac AD may improve functional capacity in BC survivors. Table: Impact of markers of cardiac AD on exercise capacity. [Table: see text]

Abstract Background The prognostic impact of heart rate (HR) in acute heart failure (AHF) patients is not well known especially in atrial fibrillation (AF) patients. Purpose The aim of the study was to evaluate the impact of admission HR, discharge HR, HR difference (HRD) (admission- discharge) in AHF patients with sinus rhythm (SR) or AF on long- term outcomes. Methods We included 1398 patients consecutively admitted with AHF between October 2013 and December 2014 from a national multicentric, prospective registry. Logistic regression models were used to estimate the association between admission HR, discharge HR and HR difference and one- year all-cause mortality and HF readmission. Results The mean age of the study population was 72±12 years. Of these, 594 (42.4%) were female, 655 (77.8%) were hypertensive and 655 (46.8%) had diabetes. Among all included patients, 745 (53.2%) had sinus rhythm and 653 (46.7%) had atrial fibrillation. Only discharge HR was associated with one-year all-cause mortality (Relative risk (RR)= 1.182, confidence interval (CI) 95% 1.024–1.366, p=0.022) in SR. In AF patients discharge HR was associated with one-year all-cause mortality (RR= 1.276, CI 95% 1.115–1.459, p≤0.001). We did not observe a prognostic effect of admission HR or HRD on long-term outcomes in both groups. This relationship is not dependent on left ventricular ejection fraction (Figure 1) Effect of post-discharge heart rate Conclusions In AHF patients lower discharge HR, neither the admission nor the difference, is associated with better long-term outcomes especially in AF patients Acknowledgement/Funding Heart Failure Program of the Red de Investigaciόn Cardiovascular del Instituto de Salud Carlos III, Madrid, Spain (RD12/0042) and the Fondo Europeo de

Abstract Background In the last two decades, catheter ablation (CA) for atrial fibrillation (AF) including pulmonary vein isolation (PVI) has been developed as a standard and effective treatment for atrial fibrillation (AF). In patients with chronic heart failure with reduced left ventricular ejection fraction (LVEF) (HFrEF), PVI CA for AF dramatically improves LVEF, resulting in better clinical prognoses. On the contrary, there still has been no data that PVI CA for AF improves the prognosis in heart failure patients with preserved LVEF (HFpEF). Purpose The aim of this study was to evaluate the prognostic impact of PVI CA for AF after the hospitalization due to decompensation of heart failureHF, focusing on LVEF. Methods From the database including 1,793 consecutive patients who were hospitalized due to congestive HF, we ultimately analyzed 624 AF patients who were discharged alive. They were assigned into two groups due that PVI CA for AF procedure done after the index hospitalization for HF; the PVI CA group (n=62) and Non-PVI CA group (n=562). For the two groups, we performed propensity-score (PS) matching using variables as follows: age, sex, LVEF, brain natriuretic peptide (BNP), blood urea nitrogen (BUN) and estimated glomerular filtration rate (eGFR) at discharge. Further analysis was performed separately in HFrEF (LVEF <50%) and HFpEF (LVEF >50%). The primary endpoint of this study was death from any cause. Results In unmatched patients, Kaplan-Meier analysis showed that patients in the PVI CA group had a significantly lower all-cause mortality than those in the Non-PVI CA group during 678 median follow-up period (Log-rank test: P=0.003, Figure A). In 96 PS-matched patients, patients in the PVI CA group still had lower mortality rate than those in the Non-PVI CA group (hazard ratio 0.28, 95% confidence interval 0.09–0.86, p=0.018, Figure B). When the whole study population was classified into HFrEF and HFpEF, HFrEF patients who received PVI showed a significantly lower mortality than those who did not (p=0.007); whereas, in HFpEF patients, PVI CA for AF did not make statistical difference in all-cause mortality (p=0.061). Conclusions In this observational study, PVI CA for AF may improve the mortality in HF patients with reduced LVEF. However, the prognostic impact of PVI CA for AF was not observed in HF patients with preserved LVEF. Funding Acknowledgement Type of funding source: None

Mild Obesity

Aims Obesity is related to better prognosis in heart failure with either reduced (HFrEF; left ventricular ejection fraction (LVEF) <40%) or preserved LVEF (HFpEF; LVEF ≥50%). Whether the obesity paradox exists in patients with heart failure and mid-range LVEF (HFmrEF; LVEF 40–49%) and whether it is independent of heart failure aetiology is unknown. Therefore, we aimed to test the prognostic value of body mass index (BMI) in ischaemic and non-ischaemic heart failure patients across the whole spectrum of LVEF. Methods Consecutive ambulatory heart failure patients were enrolled in two tertiary centres in Italy and Spain and classified as HFrEF, HFmrEF or HFpEF, of either ischaemic or non-ischaemic aetiology. Patients were stratified into underweight (BMI <18.5 kg/m2), normal-weight (BMI 18.5–24.9 kg/m2), overweight (BMI 25–29.9 kg/m2), mild-obese (BMI 30–34.9 kg/m2), moderate-obese (BMI 35–39.9 kg/m2) and severe-obese (BMI ≥40 kg/m2) and followed up for the end-point of five-year all-cause mortality. Results We enrolled 5155 patients (age 70 years (60–77); 71% males; LVEF 35% (27–45); 63% HFrEF, 18% HFmrEF, 19% HFpEF). At multivariable analysis, mild obesity was independently associated with a lower risk of all-cause mortality in HFrEF (hazard ratio, 0.78 (95% confidence interval (CI) 0.64–0.95), p = 0.020), HFmrEF (hazard ratio 0.63 (95% CI 0.41–0.96), p = 0.029), and HFpEF (hazard ratio 0.60 (95% CI 0.42–0.88), p = 0.008). Both overweight and mild-to-moderate obesity were associated with better outcome in non-ischaemic heart failure, but not in ischaemic heart failure. Conclusions Mild obesity is independently associated with better survival in heart failure across the whole spectrum of LVEF. Prognostic benefit of obesity is maintained only in non-ischaemic heart failure.

Introduction: There is conflicting data on the effect of digoxin on all-cause mortality in patients with atrial fibrillation (AF), especially in patients with heart failure (HF). Hypothesis: We hypothesized that in patients with AF, mortality rates associated with digoxin treatment are different among patients with HF and without HF. Methods: We conducted a cohort study of hospitalized patients with AF assessing the effects of digoxin on all-cause mortality. We divided patients into two groups: with and without HF. We performed Cox regression analysis to assess hazard ratios (HR) for all-cause mortality depending on digoxin treatment and used propensity score matching to adjust for differences in background characteristics between treatment groups. Results: Among 2179 consecutive patients, the median age was 73 ± 14 (table), 53% patient were male, 49% had HF, 19% were discharged on digoxin. Median left ventricular ejection fraction in the cohort was 60 (IQR 40-65). Among patients with HF, 35% had preserved, 18% had mid-range and 48% had reduced left ventricular ejection fraction. The mean follow-up time was 3 ± 2.1 years. After adjustment, in patients with HF, there was no statistically significant difference in mortality between the digoxin subgroups ( A , HR=1.01 [95% CI 0.76 to 1.35], p=0.92). In contrast, after adjustment, in patients without HF there was a statistically significant increased mortality in the digoxin subgroup ( B , HR=2.23, [95% CI 1.42 to 3.51], p<0.001). Conclusions: Digoxin use was associated with increased mortality in patients with AF and without concomitant HF. This suggests that clinicians should be careful in prescribing digoxin for rate control in AF, especially in patients without concomitant HF.

Background: The risk, correlates, and consequences of incident atrial fibrillation (AF) in patients with chronic coronary artery disease (CAD) are largely unknown. Methods and results: We analyzed incident AF during a 3-year follow-up in 5031 CAD outpatients included in the prospective multicenter CARDIONOR registry and with no history of AF at baseline. Incident AF occurred in 266 patients (3-year cumulative incidence: 4.7% (95% confidence interval (CI): 4.1 to 5.3)). Incident AF was diagnosed during cardiology outpatient visits in 177 (66.5%) patients, 87 of whom were asymptomatic. Of note, 46 (17.3%) patients were diagnosed at time of hospitalization for heart failure, and a few patients (n = 5) at the time of ischemic stroke. Five variables were independently associated with incident AF: older age (p < 0.0001), heart failure (p = 0.003), lower left ventricle ejection fraction (p = 0.008), history of hypertension (p = 0.010), and diabetes mellitus (p = 0.033). Anticoagulant therapy was used in 245 (92%) patients and was associated with an antiplatelet drug in half (n = 122). Incident AF was a powerful predictor of all-cause (adjusted hazard ratio: 2.04; 95% CI: 1.47 to 2.83; p < 0.0001) and cardiovascular mortality (adjusted hazard ratio: 2.88; 95% CI: 1.88 to 4.43; p < 0.0001). Conclusions: In CAD outpatients, real-life incident AF occurs at a stable rate of 1.6% annually and is frequently diagnosed in asymptomatic patients during cardiology outpatient visits. Anticoagulation is used in most cases, often combined with antiplatelet therapy. Incident AF is associated with increased mortality.

Abstract Objective The study aimed to investigate the functional capacity and hemodynamics at rest and during exercise in patients with chronic atrial fibrillation and severe functional symptomatic tricuspid regurgitation (AF-FTR). Background Symptoms and clinical performance of severe AF-FTR mimic the population of patients with heart failure with preserved ejection fraction (HFpEF). Severe AF-FTR is known to be associated with an adverse prognosis whereas less is reported about the clinical performance including exercise capacity and hemodynamics in patients symptomatic AF-FTR. Methods Right heart catheterization (RHC) at rest and during exercise was conducted in a group of patients with stable chronic AF-TR and compared with a group of patients with HFpEF diagnosed with cardiac amyloid cardiomyopathy (CA). All patients had preserved ejection fraction and no significant left-sided disease. Results Patients with AF-FTR demonstrated a low exercise capacity that was comparable to CA patients (TR 4.9 ± 1.2 METS vs. CA 4. 7 ± 1.5 METS; P = 0.78) with an average peak maximal oxygen consumption of 15 mL/min/kg. Right atrium pressure increased significantly more in the AF-FTR patients as compared to CA patients at peak exercise (25 ± 8 vs 19 ± 9, p < 0.01) whereas PCWP increased significantly to a similar extent in both groups (31 ± 4 vs 31 ± 8 mmHg, p = 0.88). Cardiac output (CO) was significantly lower among AF-FTR at rest as compared to CA patients (3.6 ± 0.9 vs 4.4 ± 1.3 l/min; p < 0.05) whereas both groups demonstrated a poor but comparable CO reserve at peak exercise (7.3 ± 2.9 vs 7.9 ± 3.8 l/min, p = 0.59). Conclusions AF-FTR contributes to the development of advanced heart failure symptoms and poor exercise capacity reflected in increased atrial filling pressures, reduced cardiac output at rest and during exercise sharing common features seen in HFpEF patients with other etiologies.

Introduction: Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice and is a significant risk factor for ischemic stroke and death. Digitalis has been used for more than 200 years to treat heart conditions, including AF, and its use remains controversial due to uncertain long-term morbidity and mortality. Methods: We conducted a cohort study of hospitalized patients with AF assessing the effects of digoxin on long-term all-cause mortality. Patients were divided into two groups: with and without heart failure (HF). We performed multivariable Cox regression analysis to assess hazard ratios (HR) for all-cause mortality depending on digoxin treatment and used propensity score matching to adjust for differences in background characteristics between treatment groups. Results: Among 2179 consecutive patients hospitalized with AF, the median age was 73 ± 14, and 52.5% of patients were male, 49% had HF, and 18.8% were discharged on digoxin. Median left ventricular ejection fraction in the whole cohort was 60 (IQR 40-65). Among patients with HF, 34.5% had preserved, 17.3% had mid-range and 48.1% had reduced left ventricular ejection fraction. The mean follow-up time was 3 ± 2.05 years. In patients without HF there was a statistically significant increased mortality in the digoxin subgroup after propensity score matching (HR = 2.23, 95% CI 1.42-3.51, p < 0.001). In contrast, in patients with HF, there was no difference in mortality between the treatment groups (p = 0.92). Conclusions: Digoxin use in our study was associated with increased mortality in patients with AF and without concomitant HF.

Abstract Background There is a strong association between hyperuricemia (elevated serum uric acid) and the risk of heart failure. However, it remains unclear whether prescribing urate lowering therapies have any bearing on long term clinical outcomes. Purpose In this study, we assessed the impact of urate lowering therapy treatment on the risk of adverse health outcomes (hospitalisation for heart failure and all-cause mortality) in patients with hyperuricemia and heart failure. Methods We utilised data from Clinical Practice Research Datalink (CPRD) GOLD, a UK-based primary care database linked to secondary care (Hospital Episode Statistics) and mortality data (Office of National Statistics). The study population included patients with a first record of hyperuricemia (serum uric acid &gt;7 mg/dl for men and &gt;6 mg/dl for women or a gout diagnosis) between 1990 and 2019 with a history of heart failure. Incident urate lowering therapy users were identified post hyperuricemia diagnosis. To account for potential confounding variables and potential treatment paradigm changes over the study period, a propensity score matched cohort was constructed for urate lowering therapy initiators and non-initiators within 6 month accrual blocks. Adverse health outcomes were compared between matched treatment groups using Cox regression analysis adjusted for the same variables used in the propensity score. Due to extensive treatment switching and discontinuation, on-treatment analysis was the main analysis. Results A total of 2,174 propensity score matched pairs were identified. We found that urate lowering therapy was associated with a 43% lower risk of all-cause mortality or hospitalization for heart failure (Figure 1, adjusted hazard ratio 0.57, 95% confidence interval 0.51–0.65), and a 19% lower risk of cardiovascular mortality or hospitalization for heart failure (Figure 2, adjusted hazard ratio 0.81, 95% confidence interval 0.71–0.92) within five years compared to those not on therapy (on-treatment analysis). In an intention-to-treat sensitivity analysis, urate lowering therapy was associated with a 17% lower risk of all-cause mortality or hospitalization for heart failure (adjusted hazard ratio 0.83, 95% confidence interval 0.76–0.91), and a 11% lower risk of cardiovascular mortality or hospitalization for heart failure (adjusted hazard ratio 0.89, 95% confidence interval 0.81–0.98) within five years compared to those not on urate lowering therapy. Adjusted and non-adjusted hazard ratios were consistent for all outcomes. Conclusion We found that urate lowering therapy was associated with a lower risk of adverse outcomes in hyperuricemia or gout patients with a history of heart failure. These results are consistent with the hypothesis that uric acid lowering may lead to improved outcome in patients with heart failure and hyperuricemia, emphasizing the need to investigate the potential benefits of intense uric acid lowering in prospective randomized controlled trials.
