Aims. Two thirds of patients with heart failure and preserved ejection fraction (HFpEF) have an indication for oral anticoagulation (OAC) to prevent thromboembolic events. However, evidence regarding the safety of OAC in HFpEF is limited. Therefore, our aim was to describe bleeding events and to find predictors of bleeding in a large HFpEF cohort. Methods and Results. We recorded bleeding events in a prospective HFpEF cohort. Out of 328 patients (median age 71 years (interquartile range (IQR) 67–77)), 64.6% (n = 212) were treated with OAC. Of those, 65.1% (n = 138) received vitamin-K-antagonists (VKA) and 34.9% (n = 72) non-vitamin K oral anticoagulants (NOACs). During a median follow-up time of 42 (IQR 17–63) months, a total of 54 bleeding events occurred. Patients on OAC experienced more bleeding events (n = 49 (23.1%) versus n = 5 (4.3%), p < 0.001). Major drivers of events were gastrointestinal (GI) bleeding (n = 18 (36.7%)]. HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile INR, Elderly, Drugs/Alcohol Concomitantly) score (hazard ratios (HR) of 2.15 (95% confidence interval (CI) 1.65–2.79, p < 0.001)) was the strongest independent predictor for overall bleeding. In the subgroup of GI bleeding, mean right atrial pressure (mRAP: HR of 1.13 (95% CI 1.03–1.25, p = 0.013)) and HAS-BLED score (HR of 1.74 (95% CI 1.15–2.64, p = 0.009)] remained significantly associatiated with bleeding events after adjustment. mRAP provided additional prognostic value beyond the HAS-BLED score with an improvement from 0.63 to 0.71 (95% CI 0.58–0.84, p for comparison 0.032), by C-statistic. This additional prognostic value was confirmed by significant improvements in net reclassification index (61.3%, p = 0.019) and integrated discrimination improvement (3.4%, p = 0.015). Conclusion. OAC-treated HFpEF patients are at high risk of GI bleeding. High mRAP as an indicator of advanced stage of disease was predictive for GI bleeding events and provided additional risk stratification information beyond that obtained by HAS-BLED score.

Background: Patients with Heart Failure with preserved Ejection Fraction (HFpEF) and Pulmonary Hypertension (PH) have increased right atrial (RA) pressures. Whether the higher RA pressures are related to increased afterload or overall stiffening of the heart is unknown. The aim of this study is to gain further insight into the right atrium in HFpEF-PH. Methods: This is a retrospective analysis of patients with HFpEF (no PH), HFpEF-PH and Pulmonary Arterial Hypertension (PAH) that underwent right heart catheterization and cardiac magnetic resonance (CMR) imaging. CMR was used to determine RA function by quantifying volume and strain on the 4-chamber view. Total, passive and active RA emptying fraction (RAEF) were calculated. RA stiffness was calculated by determining the slope of maximum and minimum pressure during v-wave and minimal and maximal RA volumes. Groups were compared with ANOVA and post-hoc comparison with Bonferroni correction. Results: 176 patients were included: 13 HFpEF, 33 HFpEF-PH and 130 PAH patients. Although afterload was lower in PAH and higher in HFpEF patients, as shown by mean pulmonary arterial pressure (mPAP) (41 ± 2 mmHg in HFpEF-PH vs 53 ± 21 mmHg in PAH vs 19 ± 1 mmHg in HFpEF, p<0.001) and pulmonary vascular resistance (PVR) (2.3 ± 0.3 wu/m 2 in HFpEF-PH vs 5.7 ± 0.2 wu/m 2 in PAH vs 0.4 ± 0.06 wu/m 2 in HFpEF, p<0.001), mean RA pressure was significantly higher in HFpEF-PH patients compared to both groups (Figure 1A). HFpEF-PH patients had significantly increased RA stiffness compared to HFpEF and PAH patients (Figure 1B). Total RAEF was reduced in HFpEF-PH compared to PAH and HFpEF patients: passive RAEF was similar, but active RAEF was slightly reduced in HFpEF-PH (Figure 1C). This was in line with measurements of RA longitudinal strain (Figure 1D). Conclusions: Despite lower afterload, HFpEF-PH patients have worse RA function and increased RA stiffness compared to PAH. Higher RA pressures in HFpEF-PH may reflect additional stiffening of the heart.

Background: Renal dysfunction is an important predictor of poor outcomes in patients with heart failure with preserved ejection fraction (HFpEF). Right ventricular (RV) dysfunction is implicated as one of the explanations for worsening renal function in cardiorenal syndrome. Novel right heart catheterization (RHC) parameters such as pulmonary artery pulsatility index (PAPi) and right atrial to pulmonary capillary wedge pressure ratio (RA:PCWP) have been found as predictors of RV dysfunction. However, most studies investigating these parameters have been done in the setting of myocardial infarction or left ventricular assist device implantation, with limited data on these metrics in patients with HFpEF. Objective: The purpose of this study was to determine whether novel RHC parameters such as RA:PCWP and PAPi correlate with long-term renal outcomes among patients with HFpEF. Methods: A retrospective single-center study of adult patients with a documented diagnosis of heart failure who had RHC was performed between January 2006 and December 2010 at Einstein Med ical Center Philadelphia. Selected patients also had a serum B-type natriuretic peptide level ≥100 pg/mL and a PCWP ≥15 mm Hg. Patients with an ejection fraction < 50%, including those with recovered ejection fraction, and end-stage renal disease were excluded. Results: A total of 81 patients with a clinical diagnosis of HFpEF were identified who met the inclusion criteria. On multivariate analysis, after adjusting for age, sex, race, diabetes, hypertension, and cardiac index, PAPi was associated with long-term estimated glomerular filtration rate (eGFR) (β = 3.43, 95% CI = 0.635–6.23, p = 0.017), and RA:PCWP showed a trend towards significance (β = 14.81, 95% CI = –0.096–29.73, p = 0.051). The results were unchanged after further adjustment for eGFR at the time of RHC. Conclusion: Novel hemodynamic indices obtained by RHC may have predictive value for long-term renal dysfunction in patients with HFpEF.

Introduction: We aimed to clarify clinical implications of intrarenal hemodynamics (congestion and hypoperfusion) assessed by intrarenal Doppler ultrasonography (IRD) and their prognostic impacts in patients with heart failure (HF). Methods and Results: We performed IRD and measured interlobar renal artery velocity time integral (VTI) and intrarenal venous flow (IRVF) patterns (monophasic or non-monophasic pattern) to assess intrarenal hypoperfusion and congestion in HF patients (n=341). These patients were categorized based on 1) VTI: high VTI (VTI ≥ 14.0 cm, n=231) or low VTI (VTI < 14.0 cm, n=103); and 2) IRVF: monophasic (n=36) or non-monophasic (n=305) pattern. We performed right-heart catheterization, and examined post-discharge cardiac event rate such as cardiac death and rehospitalization due to worsening HF. Regarding renal perfusion, cardiac index was positively correlated with VTI (R=0.270, P=0.040). Concerning renal congestion, levels of right atrial pressure were higher in monophasic pattern than in non-monophasic pattern (9.0 vs. 7.2 mmHg, P=0.029). Importantly, HF patients with low VTI and a monophasic IRVF pattern (subset 4) had the highest cardiac event rate ( Figure ). In the Cox proportional hazard analysis, the combination of low VTI and a monophasic IRVF pattern was found to be a strong predictor of cardiac events (HR 8.357, 95% CI 3.365-20.752). Conclusion: Intrarenal hypoperfusion and congestion assessed by IRD imaging reflected cardiac output and right atrial pressure, and was useful to risk-stratify HF patients.
