Aim. To assess clinical and demographic data, structural and functional features of the myocardium in patients with chronic heart failure (CHF) with a preserved ejection fraction in comparison with patients with CHF with an intermediate (CHF-inEF) and a reduced ejection fraction (CHF-rEF).Material and methods. The study included 186 patients with CHF I-IIB stages, I-III functional classes. One hundred and three patients had a preserved ejection fraction (EF) (≥50%), 43 — intermediate (40-49%) and 40 — reduced (<40%). All patients underwent a comprehensive clinical examination, as well as standard echocardiography.Results. Among patients with CHF-rEF, remodeling of the left ventricular myocardium by the type of concentric hypertrophy was more often observed (69,9%), and among CHF-inEF and CHF-nEF patients — by the type of eccentric hypertrophy (88,4 and 875%, respectively). Restrictive diastolic dysfunction was observed in 2,0% of patients with CHF-rEF and in 21,7% of patients with EF less than 50%.Conclusion. The severity of the clinical course of CHF does not depend on the left ventricular EF. Epidemiology and etiology of CHF-rEF has fundamental differences from CHF-inEF and CHF-nEF: CHF-rEF is more common among women over 60 years old with arterial hypertension and obesity. For patients with CHF-inFV, myocardial remodeling by the type of concentric hypertrophy and the prevalence of non-restrictive types of diastolic dysfunction are characteristic.

Background The prevalence of undetected left ventricular diastolic dysfunction is high, especially in the elderly with comorbidities. Left ventricular diastolic dysfunction is a prognostic indicator of heart failure, in particularly of heart failure with preserved ejection fraction and of future cardiovascular and all-cause mortality. Therefore we aimed to develop sex-specific diagnostic models to enable the early identification of men and women at high-risk of left ventricular diastolic dysfunction with or without symptoms of heart failure who require more aggressive preventative strategies. Design Individual patient data from four primary care heart failure-screening studies were analysed (1371 participants, excluding patients classified as heart failure and left ventricular ejection fraction <50%). Methods Eleven candidate predictors were entered into logistic regression models to be associated with the presence of left ventricular diastolic dysfunction/heart failure with preserved ejection fraction in men and women separately. Internal-external cross-validation was performed to develop and validate the models. Results Increased age and β-blocker therapy remained as predictors in both the models for men and women. The model for men additionally consisted of increased body mass index, moderate to severe shortness of breath, increased pulse pressure and history of ischaemic heart disease. The models performed moderately and similarly well in men (c-statistics range 0.60–0.75) and women (c-statistics range 0.51–0.76) and the performance improved significantly following the addition of N-terminal pro b-type natriuretic peptide (c-statistics range 0.61–0.80 in women and 0.68–0.80 in men). Conclusions We provide an easy-to-use screening tool for use in the community, which can improve the early detection of left ventricular diastolic dysfunction/heart failure with preserved ejection fraction in high-risk men and women and optimise tailoring of preventive interventions.

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 &gt;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.

The beat-to-beat dynamic Starling mechanism (DSM), the dynamic modulation of stroke volume (SV) because of breath-by-breath changes in left-ventricular end-diastolic pressure (LVEDP), reflects ventricular-arterial coupling. The purpose of this study was to test whether the LVEDP-SV relationship remained impaired in heart failure with preserved ejection fraction (HFpEF) patients after normalization of LVEDP. Right heart catheterization and model-flow analysis of the arterial pressure waveform were performed while preload was manipulated using lower-body negative pressure to alter LVEDP. The DSM was compared at similar levels of LVEDP between HFpEF patients ( n = 10) and age-matched healthy controls ( n = 12) (HFpEF vs. controls: 10.9 ± 3.8 vs. 11.2 ± 1.3 mmHg, P = 1.00). Transfer function analysis between diastolic pulmonary artery pressure (PAD) representing dynamic changes in LVEDP vs. SV index was applied to obtain gain and coherence of the DSM. The DSM gain was significantly lower in HFpEF patients than in the controls, even at a similar level of LVEDP (0.46 ± 0.19 vs. 0.99 ± 0.39 ml·m−2·mmHg−1, P = 0.0018). Moreover, the power spectral density of PAD, the input variability, was greater in the HFpEF group than the controls (0.75 ± 0.38 vs. 0.28 ± 0.26 mmHg2, P = 0.01). Conversely, the power spectral density of SV index, the output variability, was not different between the groups ( P = 0.97). There was no difference in the coherence, which confirms the reliability of the linear transfer function between the two groups (0.71 ± 0.13 vs. 0.77 ± 0.19, P = 0.87). The DSM gain in HFpEF patients is impaired compared with age-matched controls even at a similar level of LVEDP, which may reflect intrinsic LV diastolic dysfunction and incompetence of ventricular-arterial coupling. NEW & NOTEWORTHY The beat-to-beat dynamic Starling mechanism (DSM), the dynamic modulation of stroke volume because of breath-by-breath changes in left-ventricular end-diastolic pressure (LVEDP), reflects ventricular-arterial coupling. Although the DSM gain is impaired in heart failure with preserved ejection fraction (HFpEF) patients, it is not clear whether this is because of higher LVEDP or left-ventricular diastolic dysfunction. The DSM gain in HFpEF patients is severely impaired, even at a similar level of LVEDP, which may reflect intrinsic left-ventricular diastolic dysfunction.

Left ventricular hypertrophy (LVH) is the most common myocardial structural abnormality associated with heart failure with preserved ejection fraction (HFpEF). LVH is driven by neurohumoral activation, increased mechanical load, and cytokines associated with arterial hypertension, chronic kidney disease, diabetes, and other comorbidities. Here we discuss the experimental and clinical evidence that links LVH to diastolic dysfunction and qualifies LVH as one diagnostic marker for HFpEF. Mechanisms leading to diastolic dysfunction in LVH are incompletely understood, but may include extracellular matrix changes, vascular dysfunction, as well as altered cardiomyocyte mechano-elastical properties. Beating cardiomyocytes from HFpEF patients have not yet been studied, but we and others have shown increased Ca2+ turnover and impaired relaxation in cardiomyocytes from hypertrophied hearts. Structural myocardial remodeling can lead to heterogeneity in regional myocardial contractile function, which contributes to diastolic dysfunction in HFpEF. In the clinical setting of patients with compound comorbidities, diastolic dysfunction may occur independently of LVH. This may be one explanation why current approaches to reduce LVH have not been effective to improve symptoms and prognosis in HFpEF. Exercise training, on the other hand, in clinical trials improved exercise tolerance and diastolic function, but did not reduce LVH. Thus current clinical evidence does not support regression of LVH as a surrogate marker for (short-term) improvement of HFpEF.

Abstract Background and Aims Inflammation contributes to progressive renal dysfunction and increases cardiovascular mortality of patients with chronic kidney disease (CKD). The association of CKD and heart failure with preserved ejection fraction (HFpEF) is observed in up to 50%, suggesting the possibility of a shared pathophysiology. CKD and HFpEF are commonly associated with inflammation. Using a novel swine model of CKD and HFpEF, we propose that a renal-cardio inflammatory axis drives diastolic dysfunction and HFpEF in CKD and that targeting renal inflammation will improve cardiac health and reduce cardiovascular risk. Methods We developed a biopolymer-fused peptide of nuclear-factor kappa (NFk)B (ELP-p50i) that we show it blocks its activity in vitro and in vivo. NFkB is a key pro-inflammatory transcription factor that is upregulated in CKD. To test our hypothesis, we induced CKD in 10 pigs via bilateral renovascular disease and dyslipidemia. Pigs were observed for 6 weeks, renal hemodynamics quantified (multi-detector CT), then randomized to single intra-renal ELP-p50i or placebo (n=5 each), and studies repeated 8 weeks later accompanied by echocardiographic assessment. Blood pressure was continuously measured (telemetry). Blood was collected to measure circulating TNF-α and biomarkers of HF (ANP, BNP). Furthermore, kidneys and hearts were used to quantify expression of factors involved in NFkB signaling. Results CKD led to a significant loss of renal function, accompanied by left ventricular hypertrophy and diastolic dysfunction with pEF, increased renal mRNA expression of TNF-α and canonical and non-canonical mediators of NFkB signaling, and elevated systemic TNF-α, ANP, and BNP, indicating renal and cardiac dysfunction. Most of these changes were improved after intra-renal ELP-p50i, although cardiac inflammatory signaling was unchanged (Figure) suggesting the kidney as a source of inflammation that can target the heart in CKD. Conclusion We show that a renal anti-inflammatory strategy via targeted inhibition of renal NFkB improves renal and cardiac function in CKD, suggesting an inflammatory renal-cardio axis. The translational pathological features of CKD and HFpEF combined with the predictive power of the model may contribute to advance the field towards new treatments targeting renal inflammation to reduce cardiovascular risk in CKD.

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.
