Abstract Funding Acknowledgements Type of funding sources: None. Background ARNI has been shown to be superior to enalapril in long term reducing the mortality and hospitalization of heart failure (HF). However short-term effect on diastolic function remain unclear. We sought to evaluate 6 months" effects of ARNI on left ventricular (LV) diastolic parameters determined by speckle tracking and tissue Doppler imaging. Objectives This study aims to evaluate the torsional dynamics and 2D speckle tracking in heart failure with reduced ejection fraction on patients taking angiotensin receptor neprilysin inhibitors (ARNI) and non. Methods This study was carried out in Menoufia university hospitals included 60 patients of HFrEF during the period from august 2019 to January 2020. (50%) of patients was treated with traditional treatment of heart failure and the remaining was treated with ARNI. Data were collected including history and clinical examination. ECG and speckle tracking and tissue Doppler imaging was done to evaluate the diastolic function. Results Our results showed no significant difference between the two groups at baseline. There was significant improvement of the LV diastolic function. Untwist time and untwist onset showed the highly significant parameters of improvement. Conclusion This study concluded that ARNI showed short term improvement of diastolic function of the left ventricle that can be detected by STE.

Objectives Running a marathon has been equivocally associated with acute changes in cardiac performance. First-phase ejection fraction is a novel integrated echocardiographic measure of left ventricular contractility and systo-diastolic coupling which has never been studied in the context of physical activity. The aim of this study was to assess first-phase ejection fraction following recreational marathon running along with standard echocardiographic indices of systolic and diastolic function. Design and participants: Runners (n = 25, 17 males), age (mean ± standard deviation) 39 ± 9 years, were assessed before and immediately after a marathon race which was completed in 4 h, 10 min ± 47 min. Main outcome measures Central hemodynamics were estimated with applanation tonometry; cardiac performance was assessed using standard M-mode two-dimensional Doppler, tissue-doppler imaging and speckle-tracking echocardiography. First-phase ejection fraction was calculated as the percentage change in left ventricular volume from end-diastole to the time of peak aortic blood flow. Results Conventional indices of systolic function and cardiac performance were similar pre- and post-race while aortic systolic blood pressure decreased by 9 ± 8 mmHg ( P < 0.001) and first-phase ejection fraction increased by approximately 48% from 16.3 ± 3.9% to 22.9 ± 2.5% ( P < 0.001). The ratio of left ventricular transmitral Doppler early velocity (E) to tissue-doppler imaging early annular velocity (e′) increased from 5.1 ± 1.8 to 6.2 ± 1.3 ( P < 0.01). Conclusion In recreational marathon runners, there is a marked increase in first-phase ejection fraction after the race despite no other significant change in cardiac performance or conventional measure of systolic function. More detailed physiological studies are required to elucidate the mechanism of this increase.
