Abstract Funding Acknowledgements Type of funding sources: None. 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.

Background: The novel MuRF1 inhibitor EMBL205 attenuates effectively developing skeletal muscle atrophy and dysfunction in animals with heart failure with preserved ejection fraction (HFpEF, ZSF1 rat model). The impact of EMBL205 on myocardial function in the HFpEF setting is currently unknown and was evaluated in ZSF1 rats. Methods: 20 wks-old female obese ZSF1 rats received EMBL205 (12 wks, conc. of 0.1% in chow; HFpEF-EMBL205). Age-matched untreated lean (con) and obese (HFpEF) ZSF1 rats served as controls. At 32 wks of age left ventricular (LV)-, aortic valve (AV) function and LV end diastolic pressure (LVEDP) was determined by echocardiography and invasive hemodynamic measurements. LV expression of collagen 1A (Col1A) and 3A (Col3A) was assessed by qRT-PCR, MMP2 expression was obtained by zymography and perivascular fibrosis was quantified in histological sections. Results: Development of HFpEF in ZSF1 obese animals is associated with cardiac enlargement and hypertrophy, as evident by increased myocardial weight, an increase in end diastolic volume (EDV) and LV anterior and posterior wall diameters. Diastolic LV-function is disturbed with elevation of E/é, an increased LVEDP and a preserved LV ejection fraction. AV peak velocity and peak gradient are significantly increased and AV opening area (AVA) significantly decreased. Col1A and Col3A expression are increased in HFpEF animals. EMBL205 treatment results in a significant reduction of myocardial weight and a trend towards lower EDV compared to HFpEF group. EMBL205 attenuates the increase in E/é, LVEDP, AV peak gradient and the decrease of AVA. EMBL205 significantly reduces Col3A expression and a trend for Col1A expression is seen. Increased perivascular fibrosis and MMP2 expression in HFpEF is extenuated by EMBL205 treatment (table 1). Conclusions: Application of EMBL205 attenuated the development of pathological myocardial alterations associated with HFpEF in ZSF1rats due to antifibrotic effects.

Abstract OnBehalf AHF Registry Background & Aim A novel echocardiographic method to non-invasively determine left ventricular (LV) myocardial work (MyW) based on speckle-tracking derived longitudinal strain and blood pressure has recently been validated against invasive reference measurements. MyW is considered less load-dependent than LV ejection fraction (EF) and LV longitudinal strain. We investigated MyW indices in patients with reduced ejection fraction (LVEF <40%; HFrEF) and patients with preserved ejection fraction (LVEF ≥50%, HFpEF) admitted for acutely decompensated heart failure (AHF). Methods The AHF registry is a monocentric prospective follow-up study that comprehensively phenotypes consecutive patients hospitalized for AHF. Echocardiography was performed on the day of admission. MyW assessment was performed off-line using EchoPAC (GE, version 202). Here we present MyW indices and performed two-sided t-tests to analyze differences in numerical baseline covariates. Results We analyzed the echocardiograms of 94 AHF patients (72 ± 10 years; 36% female). 46 patients (49%) had an LVEF <40%, while 48 patients (51%) presented with LVEF ≥50%. HFrEF patients were younger, less often female, and hat lower blood pressure (table). Consistent with lower LVEF, HFrEF patients had less negative global longitudinal strain and lower global constructive work, when compared to HFpEF patients. Since HFrEF patients also had higher global wasted work, this yielded a lower myocardial work efficiency compared to HFpEF patients (table). Conclusions This analysis in patients with AHF exhibited marked differences in MyW indices according to subgroups with HFrEF and HFpEF, thus adding information to the classical measures of LV function. Future research has to determine whether constructive and/or wasted MyW are valuable diagnostic or therapeutic targets in patients with AHF. Abstract P803 Figure.

Exercise improves morbidity, fatality rate, and quality of life in heart failure with low ejection fraction, but fewer data available in heart failure with preserved ejection fraction (HFPEF).The purpose of this study is to test the hypothesis that exercise training might improve the longitudinal intrinsic left ventricular (LV) function in HFPEF patients.This quasi-experimental study had recruited 30 patients with HFPEF. Exercise training program had been performed for a month with a total of 20 times exercise sessions and evaluated every 2 weeks. Echocardiography was performed before sessions, second week and fourth week of exercise training. Six-minute walk tests (6MWTs) and quality-of-life variables using Minnesota living with HF scoring and the 5-item World Health Organization Well-Being Index scoring were measured before and after exercise as well.Left ventricular filling pressure, represented by the ratio of early diastolic mitral flow velocity/early diastolic annular velocity and left atrial volume index, improved during exercise. The longitudinal intrinsic LV function, represented by four-chamber longitudinal strain, augmented during exercise (p < 0.001). Aerobic capacity, measured by 6MWT, increased significantly (p = 0.001). Quality of life improved significantly during exercise (p < 0.001).Exercise training was suggested to improve the longitudinal intrinsic LV function and quality of life in HFPEF.

Abstract Objectives To investigate the association between global longitudinal strain (GLS) using feature tracking (FT) cardiovascular magnetic resonance imaging (CMR) and prognosis in patients with heart failure and preserved ejection fraction (HFpEF). Background Echocardiography-based studies have demonstrated that in HFpEF left ventricular (LV) strain analyses can detect impaired systolic function despite preserved ejection fraction and might also predict outcome. CMR also allows strain analysis using FT and is furthermore the gold standard for assessment of ventricular volumes and ejection fractions. In addition, T1-mapping allows non-invasive tissue characterization. However, the prognostic relevance of FT-CMR is unknown. In addition right ventricular (RV) FT-CMR is poorly investigated. Methods Consecutive patients with confirmed diagnosis of HFpEF underwent CMR on a 1.5T scanner. We used dedicated software (cvi42, Circle Cardiovascular Imaging Inc.) for global longitudinal left ventricular strain (LV-GLS) in a 3D and global longitudinal RV strain (RV-GLS) in a 2D model using feature tracking (FT). In addition, we performed uni- and multivariable Cox regression using a combined endpoint of heart failure hospitalizations, and cardiovascular death to determine the prognostic relevance of FT-CMR. Results We included a total of 131 HFpEF patients (70.4±8.6 years old, 70.2% female). Median LV-GLS by FT-CMR was −8% [IQR: −10% to 5%] and median RV-GLS was −11.9% [IQR: −16.57% to −12.23%]. LV and RV GLS values were significantly correlated with LV and RV ejection fractions (r=−0.463, p<0.001 for LV, and r=−0.306, p=0.001 and RV, respectively). 77 (58.8%) events were recorded during a follow-up of 42.0±31.4 months. Patients with an LV-GLS worse than the median (−8%) showed a significantly reduced event-free survival rate (log-rank, p=0.009).In a multivariable Cox-regression model correcting for the strongest clinical variables, including age (HR 1.018 [0.985–1.052], p=0.290), GFR (HR 0.987 [0.975–1.000], p=0.055), diabetes (HR 1.696 [1.028–2.799], p=0.039), and 6-min-walking distance (HR 0.997 [0.995–0.999)], p=0.014), LV-GLS remained significantly associated with outcome (HR 1.093 [1.039–1.150], p=0.001) while RV-GLS had no effect on outcome (p>0.05). Conclusions In patients with HFpEF, LV-GLS but not RV-GLS by FT-CMR is significantly associated with cardiovascular events.

Abstract Aims To date, clinical evidence of microvascular dysfunction in patients with heart failure (HF) with preserved ejection fraction (HFpEF) has been limited. We aimed to investigate the prevalence of coronary microvascular dysfunction (CMD) and its association with systemic endothelial dysfunction, HF severity, and myocardial dysfunction in a well defined, multi-centre HFpEF population. Methods and results This prospective multinational multi-centre observational study enrolled patients fulfilling strict criteria for HFpEF according to current guidelines. Those with known unrevascularized macrovascular coronary artery disease (CAD) were excluded. Coronary flow reserve (CFR) was measured with adenosine stress transthoracic Doppler echocardiography. Systemic endothelial function [reactive hyperaemia index (RHI)] was measured by peripheral arterial tonometry. Among 202 patients with HFpEF, 151 [75% (95% confidence interval 69–81%)] had CMD (defined as CFR <2.5). Patients with CMD had a higher prevalence of current or prior smoking (70% vs. 43%; P = 0.0006) and atrial fibrillation (58% vs. 25%; P = 0.004) compared with those without CMD. Worse CFR was associated with higher urinary albumin-to-creatinine ratio (UACR) and NTproBNP, and lower RHI, tricuspid annular plane systolic excursion, and right ventricular (RV) free wall strain after adjustment for age, sex, body mass index, atrial fibrillation, diabetes, revascularized CAD, smoking, left ventricular mass, and study site (P < 0.05 for all associations). Conclusions PROMIS-HFpEF is the first prospective multi-centre, multinational study to demonstrate a high prevalence of CMD in HFpEF in the absence of unrevascularized macrovascular CAD, and to show its association with systemic endothelial dysfunction (RHI, UACR) as well as markers of HF severity (NTproBNP and RV dysfunction). Microvascular dysfunction may be a promising therapeutic target in HFpEF.

Abstract Introduction. Randomized controlled trials and meta-analyzes have shown high efficacy of the radiofrequency ablation (RFA) for both initial and secondary strategies after unsuccessful drug therapy (DT) to maintain sinus rhythm (SR) and improve functional and morphological quality of life; in patients with chronic heart failure (CHF), RFA were associated with a significant relative reduction in the risk of overall mortality, atrial fibrillation (AF) recurrence, and hospitalization for cardiac pathology (compared with DT). High risk of arrhythmia recurrence (up to 45% within 6 - 12 months after intervention) remains a major RFA problem. Purpose. to evaluate predictive properties of demographic, hemodynamic and electrocardiographic parameters for recurrence after atrial fibrillation ablation in patients with chronic heart failure with preserved ejection fraction. Methods. We included 120 patients, aged 59.80 ± 10.08 years with CHF with preserved ejection fraction (EF) of left ventricle (LV) who underwent first time RFA for AF with LV EF(&gt; 40%) I-III FC NYHA. Baseline clinical data, ECG before and after the procedure, ECHO parameters were collected Results Thirty-two patients had AF recurrence after a mean follow-up of twelve months. Those experiencing recurrence were more female (50% vs.39%, p &lt;0,01), had a longer QTc interval before ablation than those without recurrence (387,23 ± 2,31 vs. 341,22 ± 8,91 ms, p &lt; 0,01) and after ablation (439,01 ± 4,73 vs. 373,21 ± 7,92 ms, p &lt; 0,001), lower LV EF (59% vs. 63%, p &lt; 0,05), higher left atrium diameter (4,59 ± 0,45 vs. 4,08 ± 0,61 cm, p &lt; 0,001) and higher mean pulmonary artery gradient (32,86 ± 9,67 vs. 25,15 ± 9,73, p &lt; 0,01). Conclusions. QTc duration to radiofrequency ablation and its prolongation after intervention are independent predictors of arrhythmia recurrence in patients with chronic heart failure with a preserved left ventricular ejection fraction. The size of the left atrium before ablation is a highly sensitive predictor of recurrence of arrhythmia

Abstract Background Atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) are common diseases and associated with increased morbidity and mortality, which even aggravates if both conditions are coexisting. Coronary artery disease (CAD) is highly prevalent in both, patients with AF (17-46%) and HFpEF (50-80%). Notably, all three entities share several common risk factors. While it is well established that the emergence of the vicious twins HFpEF and AF is mechanistically linked, CAD can also be pathophysiological related to HFpEF, as well as AF by several mechanisms. Aim The study aimed to evaluate the influence of CAD on patients with concomitant AF and HFpEF and to identify parameters affecting the patients clinical outcome. Methods We retrospectively screened patients with AF and HFpEF for CAD. Patients with and without CAD were compared by relevant patient characteristics and echocardiographic parameters at baseline and at the end of follow-up. Additionally, we assessed hospitalization rates and  performed multivariate logistic regression to analyze parameters influencing the clinical outcome.  Results Between January 2013 and December 2016 6.114 patients with atrial fibrillation and 2.187 patients with echocardiographic diastolic dysfunction were treated at our university hospital department. Of those, 127 patients had concomitant diagnosis of HFpEF according to current guidelines and AF. In 77 patients (61%) CAD had been diagnosed by coronary angiography. At baseline, CAD patients had significantly more myocardial infarction, dyslipidemia, use of aspirin, lower left ventricular ejection fraction, larger left ventricular diastolic diameter and a higher CHA2DS2-VAsc score. Moreover, CAD patients had significantly higher rates of all-cause and cardiovascular hospitalizations. Interestingly, NYHA-class and left ventricular mass index improved significantly in the group without CAD, whereas there was no change in the CAD-group. Multivariate logistic regression only associated catheter ablation for AF significantly with NYHA improvement in the total cohort. Assessment of all-cause and cardiovascular hospitalization in CAD patients undergoing either catheter ablation or medical therapy revealed, that catheter ablation significantly decreased event rates. Moreover, catheter ablation for AF was associated with echocardiographic signs of reverse remodelling, whereas conservative treatment resulted in progression of remodelling.  Conclusion This is the first study to evaluate the effect of CAD on patients with concomitant AF and HFpEF. As expected, presence of CAD was related to a worse clinical outcome. Interestingly, in CAD patients catheter ablation was significantly associated with functional and clinical improvement. In conclusion, catheter ablation for AF might display an effective therapeutic approach in this vulnerable population.
