Abstract BACKGROUND Heart failure with preserved ejection fraction (HFpEF) is characterized by heart failure symptoms despite preserved LV systolic function together with at least one among left ventricle hypertrophy/left atrial enlargement plus diastolic dysfunction (DD) and increased brain natriuretic peptide levels. Rest echocardiography could still be normal despite patients experience HF symptoms. Speckle tracking analysis (STE) analyzes myocardial deformation and is able to identify subtle left ventricular dysfunction. PURPOSE to analyze the added value of stress echocardiography to improve diagnostic accuracy in patients with normal ejection fraction and unexplained dyspnoea by evaluating DD, lung B lines and STE. METHODS Main inclusion criteria were: suspected heart failure, EF > 40%, DD up to moderate at rest (E/e"<14), age < 85 and >18 years, satisfactory acoustic window. Exclusion criteria were: comorbidities limiting the prognosis, valvulopathy more than moderate, coronary artery disease, moderate to severe DD at rest (E/e"≥14; E/A≥2), pregnancy or lactation. Each patient underwent physical stress echo and STE by GE Vivid 7, (AFI). RESULTS After measuring diastolic function parameters variation with stress, HFpEF was diagnosed in 8 patients, who had baseline non-diagnostic echocardiogram (Table 1). In the remaining 20 patients a non-cardiac etiology of dyspnoea was diagnosed (NCD). EF did not significantly change from rest to stress either in HFpEF group (58 ± 6 vs 61 ± 8.7 p:0.62) or in DNC group (59 ± 8 vs 62.2 ± 7.4; p:0.26). GLS values tended to decrease in patients with HFpEF (-18.5 ± 2.2 at baseline vs -15.96 ± 6.67 at peak stress; p:0.33), and it was stable in DNC (-17.69 ± 1.15 at baseline vs - 18.04 ± 2.02 at peak stress; p:0.64). CONCLUSIONS Study of diastolic function during stress echocardiography is a useful diagnostic tool to reveal HFpEF in patients with dyspnea and unremarkable baseline echocardiogram. STE could offer useful adjunctive diagnostic information but further studies are needed to confirm its value.

AbstractThe aim of the paper is to investigate the utility of left atrial longitudinal strain (LALS) in the diagnosis of heart failure with preserved ejection fraction (HFpEF) when left ventricular diastolic function is indeterminable and the assessment of natriuretic peptides is not routinely performed.Method. The study included 180 patients with signs and symptoms suggestive of non-acute heart failure, examined clinically and echocardiographically, both conventionally and via speckle tracking method.Results. 33 patients had a normal echocardiographic examination. Diastolic dysfunction (DD) was present in 116 patients of whom 32 patients had grade I, 66 patients grade II, 18 patients grade III DD. Diastolic function could not be determined in 31 patients. The mean value of LALS and NTproBNP in patients with normal echocardiography was significantly different from the group with DD for both variables (p<0.001). LALS was inversely correlated with the grade of DD (r=-0.83, p<0.001). The cut-off value of LALS for predicting DD was 25%. Applying this value in patients with indeterminate diastolic function we identified 21 patients with HFpEF (p<0.001).Conclusions. LALS can help in the diagnosis of HFpEF when other echocardiographic criteria are irrelevant and NTproBNP is not routinely performed. LALS was correlated with the presence and severity ofDDwith a cut-off value of 25%.

Abstract Background Central apneas (CA) and obstructive apneas (OA) are highly prevalent in heart failure (HF) both with reduced and preserved systolic function. However, a comprehensive evaluation of apnea prevalence across HF according to ejection fraction (i.e HF with patients with reduced, mid-range and preserved ejection fraction- HFrEf, HFmrEF and HFpEF, respectively) throughout the 24 hours has never been done before. Materials and methods 700 HF patients were prospectively enrolled and then divided according to left ventricular EF (408 HFrEF, 117 HFmrEF, 175 HFpEF). All patients underwent a thorough evaluation including: 2D echocardiography; 24-h Holter-ECG monitoring; cardiopulmonary exercise testing; neuro-hormonal assessment and 24-h cardiorespiratory monitoring. Results In the whole population, prevalence of normal breathing (NB), CA and OA at daytime was 40%, 51%, and 9%, respectively, while at nighttime 15%, 55%, and 30%, respectively. When stratified according to left ventricular EF, CA prevalence decreased from HFrEF to HFmrEF and HFpEF: (daytime CA: 57% vs. 43% vs. 42%, respectively, p=0.001; nighttime CA: 66% vs. 48% vs. 34%, respectively, p&lt;0.0001), while OA prevalence increased (daytime OA: 5% vs. 8% vs. 18%, respectively, p&lt;0.0001; nighttime OA: 20 vs. 29 vs. 53%, respectively, p&lt;0.0001). When assessing moderte-severe apneas, defined with an apnea/hypopnea index &gt;15 events/hour, prevalence of CA was again higher in HFrEF than HFmrEF and HFpEF both at daytime (daytime moderate-severe CA: 28% vs. 19% and 23%, respectively, p&lt;0.05) and at nighttime (nighttime moderate-severe CA: 50% vs. 39% and 28%, respectively, p&lt;0.05). Conversely, moderate-severe OA decreased from HFrEF to HFmrEF to HFpEF both at daytime (daytime moderate-severe OA: 1% vs. 3% and 8%, respectively, p&lt;0.05) and nighttime (noghttime moderate-severe OA: 10% vs. 11% and 30%, respectively, p&lt;0.05). Conclusions Daytime and nighttime apneas, both central and obstructive in nature, are highly prevalent in HF regardless of EF. Across the whole spectrum of HF, CA prevalence increases and OA decreases as left ventricular systolic dysfunction progresses, both during daytime and nighttime.

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.
