Abstract Background E/e' and the ratio of diastolic elastance (Ed)/arterial elastance (Ea) = (E/e')/(0.9 × systolic blood pressure), indices of left atrial (LA) pressure overload, are elevated in elderly women with heart failure with preserved ejection fraction (HFpEF). The severity of diastolic dysfunction is assessed by a combination of several indices of LA volume and pressure overload. However, which overload is more important as a single factor for the prognosis of these patients remains undefined. Methods We enrolled patients with HFpEF showing sinus rhythm (n=145; left ventricular ejection fraction >50%; men/women, 56/89; mean age, 80.5 years). Blood examination and transthoracic echocardiography were performed before discharge. All-cause mortality and admission for cardiac events were evaluated after more than 1 year (mean, 370 days). Results The all-cause mortality rate was 11% (16/145). There were significant differences in age (p=0.005), serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level (p<0.001), LA volume index (p=0.018), E/e' (p=0.022), and Ed/Ea (p=0.016) between patients with and without all-cause mortality. When cutoff points for mortality by receiver operating characteristic curve analysis were examined, the area under the curve in LA volume index (0.564) was slightly smaller than that in age (0.734), NT-proBNP level (0.732), E/e' (0.695), and Ed/Ea (0.709). Kaplan-Meier survival analysis clearly showed that age >85 years (p<0.001), NT-proBNP level >888 pg/mL (p=0.003), E/e' >14.4 (p=0.020), and Ed/Ea >0.153 (p<0.001) were determinant factors for mortality. Cox hazard ratios were also significant in these indices (p=0.002, p=0.012, p=0.028, and p=0.001, respectively). In the case of all-cause mortality or admission for cardiac events, the results were nearly similar as those in the case of all-cause mortality. Ed/Ea exhibited a larger Cox hazard ratio for prognosis than E/e' in the multivariate analysis. Conclusions LA pressure overload compared to volume overload was a useful marker for prognosis in elderly patients with HFpEF. As a single index for LA pressure overload in noninvasive echocardiographic findings, Ed/Ea may be more suitable than E/e'.

Objective: We aimed to clarify the differences in the significance of the ratio of diastolic elastance (Ed) to arterial elastance (Ea), [Ed/Ea=(E/e’)/(0.9 х systolic blood pressure)], a relative index of left atrial (LA) pressure overload, in relation to N-terminal pro-brain natriuretic peptide (NT-proBNP) level on prognosis between patients with heart failure with preserved ejection fraction (HFpEF) with and without atrial fibrillation (AF). Methods: We studied 297 HFpEF patients hospitalized for acute decompensated heart failure (sinus rhythm/AF: 192/105). Blood testing and transthoracic echocardiography were performed before discharge. All-cause mortality was evaluated at >1 year after discharge. Results: During a median follow-up of 626 days, 47 patients (sinus rhythm/AF: 30/17) had all-cause mortality. In the subgroup with sinus rhythm, but not AF, Ed/Ea was significantly higher in patients with than without all-cause mortality. In a multivariate Cox hazard analysis, Ed/Ea was significantly associated with all-cause mortality independent of NT-proBNP in patients with sinus rhythm, but not with AF. Among patients with higher NT-proBNP levels, the effect of higher Ed/Ea on prognosis was prominent only in those with sinus rhythm (p=0.037). Conclusions: Ed/Ea provides additional prognostic information to serum NT-proBNP level for predicting all-cause mortality only in HFpEF patients with sinus rhythm. The prognostic risk factors differed between elderly HFpEF patients with and without AF.

Abstract Funding Acknowledgements Type of funding sources: None. Background and Aim Left atrial (LA) enlargement and impaired LA function are frequently found in patients with heart failure with preserved ejection fraction (HFpEF). Whether these structural and functional LA abnormalities are a consequence of increased LA pressure or whether HFpEF patients have an intrinsic LA myopathy is unknown. We compared LA pressure, size and function between patients with HFpEF and aortic stenosis, as a comparator with LA pressure overload, as well as community-dwelling control subjects. Methods Extensive echocardiographic assessments were performed in 219 patients with HFpEF (age 68 ± 11, 48% female), 173 patients with moderate to severe AS (age 69 ± 11, 55% female, aortic valve area index 0.55 ± 0.15 cm2/m2), and 219 controls (age 65 ± 9, 48% female, 42.2% hypertensive) Results Compared to controls, both patients with HFpEF and AS had larger LV and LA size and worse LV systolic, diastolic and LA function. Compared with AS patients, HFpEF patients had smaller LA volume index (40.2 ± 19.4 vs. 44.5 ± 11.9 ml/m2 p = 0.01) but similar LV filling pressure estimated by E/e’ (13.4 ± 4.8  13.4 ± 4.8 , p = 0.12). Despite smaller LA volume index and similar LV filling pressure, HFpEF patients had remarkably poorer LA function compared to AS [reservoir GLS, 22.6 ± 10% vs 31.4 ± 10.1 (p &lt; 0.001); contractile GLS, 15.8 ± 6.1% vs 17.5 ± 6.9 (p &lt; 0.05); LASrs, 0.92 ± 0.35% vs 1.27 ± 0.41 (p &lt; 0.001); LASre, -1.49 ± 0.65 vs -1.86 ± 0.67 (p &lt; 0.001)]. The differences in  LA reservoir GLS and LASrs remained significant  after adjustment for atrial fibrillation, diabetes, coronary artery disease, LV ejection fraction and LV mass index. Conclusion Patients with HFpEF had significantly worse LA function than patients with AS, despite similar LA pressure overload. These findings support the concept of an intrinsic LA myopathy in patients with HFpEF, beyond LA pressure overload. Abstract Figure.

Echocardiographic Parameters

Abstract Background Novel echocardiographic software allows for layer-specific evaluation of myocardial deformation by 2-dimensional speckle tracking echocardiography. Endocardial, epicardial- and whole wall global longitudinal strain (GLS) may be superior to conventional echocardiographic parameters in predicting all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF). Purpose The purpose of this study was to investigate the prognostic value of endocardial-, epicardial- and whole wall GLS in patients with HFrEF in relation to all-cause mortality. Methods We included and analyzed transthoracic echocardiographic examinations from 1,015 patients with HFrEF. The echocardiographic images were analyzed, and conventional and novel echocardiographic parameters were obtained. A p value in a 2-sided test &lt;0.05 was considered statistically significant. Cox proportional hazards regression models were constructed, and both univariable and multivariable hazard ratios (HRs) were calculated. Results During a median follow-up time of 40 months, 171 patients (16.8%) died. A lower endocardial (HR 1.17; 95% CI (1.11–1.23), per 1% decrease, p&lt;0.001), epicardial (HR 1.20; 95% CI (1.13–1.27), per 1% decrease, p&lt;0.001), and whole wall (HR 1.20; 95% CI (1.14–1.27), per 1% decrease, p&lt;0.001) GLS were all associated with higher risk of death (Figure 1). Both endocardial (HR 1.12; 95% CI (1.01–1.23), p=0.027), epicardial (HR 1.13; 95% CI (1.01–1.26), p=0.040) and whole wall (HR 1.13; 95% CI (1.01–1.27), p=0.030) GLS remained independent predictors of mortality in the multivariable models after adjusting for significant clinical parameters (age, sex, total cholesterol, mean arterial pressure, heart rate, ischemic cardiomyopathy, percutaneous transluminal coronary angioplasty and diabetes) and conventional echocardiographic parameters (left ventricular (LV) ejection fraction, LV mass index, left atrial volume index, deceleration time, E/e', E-velocity, E/A ratio and tricuspid annular plane systolic excursion). No other echocardiographic parameters remained an independent predictors after adjusting. Furthermore, endocardial, epicardial and whole wall GLS had the highest C-statistics of all the echocardiographic parameters. Conclusion Endocardial, epicardial and whole wall GLS are independent predictors of all-cause mortality in patients with HFrEF. Furthermore, endocardial, epicardial and whole wall GLS were superior prognosticators of all-cause mortality compared with all other echocardiographic parameters.

Background: Exercise-based cardiac rehabilitation (CR) improves health-related quality of life and exercise capacity in patients with heart failure (HF). However, CR efficacy in patients with HF who are elderly, frail, or have HF with preserved ejection fraction remains unclear. We examined whether participation in multidisciplinary outpatient CR is associated with long-term survival and rehospitalization in patients with HF, with subgroup analysis by age, sex, comorbidities, frailty, and HF with preserved ejection fraction. Methods: This multicenter retrospective cohort study was performed in patients hospitalized for acute HF at 15 hospitals in Japan, 2007 to 2016. The primary outcome (composite of all-cause mortality and HF rehospitalization after discharge) and secondary outcomes (all-cause mortality and HF rehospitalization) were analyzed in outpatient CR program participants versus nonparticipants. Results: Of the 3277 patients, 26% (862) participated in outpatient CR. After propensity matching for potential confounders, 1592 patients were included (n=796 pairs), of which 511 had composite outcomes (223 [14%] all-cause deaths and 392 [25%] HF rehospitalizations, median 2.4-year follow-up). Hazard ratios associated with CR participation were 0.77 (95% CI, 0.65–0.92) for composite outcome, 0.67 (95% CI, 0.51–0.87) for all-cause mortality, and 0.82 (95% CI, 0.67–0.99) for HF-related rehospitalization. CR participation was also associated with numerically lower rates of composite outcome in patients with HF with preserved ejection fraction or frail patients. Conclusions: Outpatient CR participation was associated with substantial prognostic benefit in a large HF cohort regardless of age, sex, comorbidities, frailty, and HF with preserved ejection fraction.

Background Increases in heart rate are thought to result in incomplete left ventricular (LV) relaxation and elevated filling pressures in patients with heart failure with preserved ejection fraction (HFpEF). Experimental studies in isolated human myocardium have suggested that incomplete relaxation is a result of cellular Ca 2+ overload caused by increased myocardial Na + levels. We tested these heart rate paradigms in patients with HFpEF and referent controls without hypertension. Methods and Results In 22 fully sedated and instrumented patients (12 controls and 10 patients with HFpEF) in sinus rhythm with a preserved ejection fraction (≥50%) we assessed left‐sided filling pressures and volumes in sinus rhythm and with atrial pacing (95 beats per minute and 125 beats per minute) before atrial fibrillation ablation. Coronary sinus blood samples and flow measurements were also obtained. Seven women and 15 men were studied (aged 59±10 years, ejection fraction 61%±4%). Patients with HFpEF had a history of hypertension, dyspnea on exertion, concentric LV remodeling and a dilated left atrium, whereas controls did not. Pacing at 125 beats per minute lowered the mean LV end‐diastolic pressure in both groups (controls −4.3±4.1 mm Hg versus patients with HFpEF −8.5±6.0 mm Hg, P =0.08). Pacing also reduced LV end‐diastolic volumes. The volume loss was about twice as much in the HFpEF group (controls −15%±14% versus patients with HFpEF −32%±11%, P =0.009). Coronary venous [Ca 2+ ] increased after pacing at 125 beats per minute in patients with HFpEF but not in controls. [Na + ] did not change. Conclusions Higher resting heart rates are associated with lower filling pressures in patients with and without HFpEF. Incomplete relaxation and LV filling at high heart rates lead to a reduction in LV volumes that is more pronounced in patients with HFpEF and may be associated with myocardial Ca 2+ retention.
