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 Funding Acknowledgements Type of funding sources: None. Background Left atrial (LA) function is impaired in heart failure with preserved ejection fraction (HFpEF). However, the association between LA longitudinal strain and heart failure (HF) events in patients with HFpEF is still unknown. We evaluated whether LA strain measurements would be useful to predict hospitalizations for worsening HF in this study. Methods This study included 121 patients (Male 73, Female 48) with HFpEF who had echocardiogram at our institute (Age = 76 ± 14y, Left ventricular ejection fraction; LVEF = 63 ± 8%). Patients with atrial fibrillation were excluded. LA longitudinal strain was measured by speckle-tracking echocardiography, using TOMTEC imaging system. The endpoints were hospitalizations for worsening HF. Results During follow-up period of 319 ± 269 days, 33 patients (27%) experienced hospitalizations for worsening HF. LA strain was markedly lower in patients with HF events at 11.3 ± 5.6, whereas LA strain was higher at 20.3 ± 10.1 in patients without HF events. Kaplan-Meier analysis demonstrated a significant separation of survival curves stratified by median value of LA strain (Figure). Conclusions LA dysfunction in HFpEF is associated with a higher risk of HF hospitalization, and LA strain measurements would be useful to predict HF events. Abstract Figure

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 &gt; 40%, DD up to moderate at rest (E/e"&lt;14), age &lt; 85 and &gt;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.
