Background: Both Left ventricular (LV) global longitudinal strain (GLS) and LV ejection fraction (LVEF) are useful parameters for assessment of LV function. The aim of this study is to confirm the prognostic value of them in patients with non-ischemic and ischemic heart disease. Methods: We studied 179 patients (DCM group: Age 61±15 years, 70 females, LVEF 33±9%) with non-ischemic dilated cardiomyopathy and heart failure symptom, and 97 patients (MI group: Age 66±13 years, 18 females, LVEF 45±7%) who were successfully treated with percutaneous coronary intervention for acute anteroseptal myocardial infarction. Echocardiography was used for LV GLS derived from 2D speckle-tracking method and LVEF with modified Simpson’s method. Outcome was assessed according to death and re-hospitalization with heart failure in the follow-up period. Results: 40 patients in DCM group and 10 patients in MI group experienced at least one event. In these 2 groups, significant differences in GLS and LVEF were found between patients with and without cardiac events (p<0.05). Kaplan-Meier analysis showed patients with worse GLS had an unfavorable outcome in both DCM and MI groups (p<0.05), but LVEF did not associated with outcome. Conclusion: LV GLS has the potential to predict the outcome with higher sensitivity than LVEF in patients with heart disease regardless of ischemic etiology.

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 &lt;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 &lt;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.

Background: The left ventricular ejection fraction (LVEF) guides treatment of heart failure, yet this data has not been systematically collected in large data sets. We sought to characterize the epidemiology of incident heart failure using the initial LVEF. Methods: We identified 219 537 patients in the Veterans Affairs system between 2011 and 2017 who had an LVEF documented within 365 days before and 30 days after the heart failure diagnosis date. LVEF was obtained from natural language processing from imaging and provider notes. In multivariate analysis, we assessed characteristics associated with having an initial LVEF <40%. Results: Most patients were male and White; a plurality were within the 60 to 69 year age decile. A majority of patients had ischemic heart disease and a high burden of co-morbidities. Over time, presentation with an LVEF <40% became slightly less common, with a nadir in 2015. Presentation with an initial LVEF <40% was more common in younger patients, men, Black and Hispanic patients, an inpatient presentation, lower systolic blood pressure, lower pulse pressure, and higher heart rate. Ischemic heart disease, alcohol use disorder, peripheral arterial disease, and ventricular arrhythmias were associated with an initial LVEF <40%, while most other comorbid conditions (eg, atrial fibrillation, chronic obstructive pulmonary disease, malignancy) were more strongly associated with an initial LVEF >50%. Conclusions: For patients with heart failure, particularly at the extremes of age, an initial preserved LVEF is common. In addition to clinical characteristics, certain races (Black and Hispanic) were more likely to present with a reduced LVEF. Further studies are needed to determine if racial differences are due to patient or health systems issues such as access to care.

Background: The clinical development program of sacubitril/valsartan (sac/val) for heart failure with reduced ejection fraction (HFrEF) only included a very limited number of patients being naive to prior angiotensin converting enzyme inhibitors (ACEis) or angiotensin II receptor antagonists (ARBs). Recent studies support the use of sac/val in hospitalised HF patients without prior ACEis/ARBs. This study aims to compare HF patients newly prescribed either sac/val or ACEis/ARBs. Methods: Retrospective non-interventional cohort study describing two mutually exclusive adult patient cohorts diagnosed with HFrEF either initiating sac/val or ACEis/ARBs. All patients were naive to both sac/val and ACEis/ARBs for 12 months prior to the first prescription. All patients had a left ventricular ejection fraction (LVEF) ≤40%. Patients were identified any time between 1 st July 2015 and 31 st Dec 2018 in the Optum® de-identified EHR dataset from providers across the continuum of care. Results: 2,414 patients were initiated on sac/val, 36,563 on ACEis/ARBs. Mean age was 66.1 (SD 12.9) and 67.2 years (SD 13.7) for sac/val and ACEis/ARBs users, respectively. Sac/val patients were more likely to be male: 70.8% vs 67.2% (p<0.0001) and had a lower mean LVEF: 26.9% vs 29.3% (p<0.0001). Patients newly initiated on sac/val had similar proportion of ischemic heart disease (67.9% vs 68.2%, p=0.72), and more often valvular heart disease (48.6% vs 44.3%, p<0.0001), and use of cardio resynchronization therapy device (40.9% vs 24.0%, p<0.0001). Conclusions: This real-world study indicates that sac/val tends to be newly prescribed to younger, male HFrEF patients with lower LVEF and a higher proportion of cardio resynchronization therapy devices compared with patients newly initiated on ACEis/ARBs. The prevalence of ischemic heart disease is similar between the groups.

Abstract Background Previous studies demonstrated that 2 D strain imaging segmental transverse diastolic index is a marker of regional ischemia and that global longitudinal strain diastolic index (GLSDI) correlates with left ventricular (LV) filling pressures and NTproBNP. However, usefulness of GLSDI in clinical practice has to be established. Purpose The aim of the study is to examine the utility of global longitudinal strain diastolic index in the assessment of patients with suspected ischemic heart disease (IHD). Methods We performed 2 D standard echocardiography and strain imaging in 30 healthy subjects and in 148 patients with stable angina with indication for coronarography. Patients with severe symptoms, severe valvulopathy, arrythmia and/or ejection fraction (EF) less than 45% were excluded. Standard echocardiographic parameters, left ventricular global longitudinal strain (LVGLS) and global longitudinal strain diastolic index were analysed. The patients subsequently underwent coronary angiographic examination. Results GLSDI was significantly lower in angina pectoris vs control group (0.41 vs 0,69, p &lt;0.001). After coronarography patients were divided in three subgroups: 74 patients (50%) with more than 50% obstruction in any major artery, 26 patients (17.5%) with previous revascularisation but no significant obstructive lesions at present and 48 patients (32.5%) without obstructive artery disease. Average GLSDI was significantly lower in the subgroup with obstructive coronary disease vs the other two subgroups (0.32 vs 0.41 and 0.46 respectively, p &lt; 0.05). Mean LVEF was different in subgroups but with no statistical significance (50 % vs 48 % vs 54 %, p= 0.08). Mean LVGLS was lower in the obstructive artery disease subgroup (-16.4% vs -18.2% vs -21% respectively, p&lt; 0.05). In univariate analysis lower GLSDI was associated with a higher risk of coronary artery disease (Hazard Ratio 1.39, 95% Confidence Interval 1.09-1.49; p &lt; 0.05 per 0.1% decrease). There was significant correlation between reduced GLSDI and the presence of coronary artery disease (r= -0,54, P &lt; 0.05), hypertension (r=- 0.61, p &lt; 0.05), left ventricular hypertrophy (-0.68, p &lt; 0.05) and diastolic disfunction (-0.69, p &lt; 0.05). GLSDI lower than 0.5 had a good sensitivity (84%) and negative predictive value (71%) and a lower specificity (40%) and positive predictive value (52%) for detection of ischemic heart disease. Conclusions Global longitudinal strain diastolic index is significantly lower in patients with stable angina and normal or borderline reduced ejection fraction compared with normal subjects. A cut off value lower than 0.5 selects patients with a higher probability of obstructive coronary heart disease.

Abstract Background Heart failure with mid-range ejection fraction (HFmrEF) was defined as the typical symptoms of HF with a left ventricular ejection fraction (LVEF) of 41% to 49%. However, till now the progression of LV function and the subsequent prognosis remains largely unknown. Speckle tracking echocardiography (STE) is a novel method to detect the early myocardial dysfunction and has been used to differentiate the outcomes of different phenotypes of cardiovascular diseases. Purpose Herein, we aim to investigate the application of STE in HFmrEF and its predictive values. Methods Retrospectively, we collected the medical records and echocardiography imaging of 250 patients diagnosed as HFmrEF during 2014 to 2018. LV longitudinal strain at diagnosis was evaluated and compared with the changes of LV during the follow-up period. Also, mortality and major adverse cardiovascular events (MACE) including myocardial infarction, heart failure requiring admission were recorded. Results Our result indicated that a reduced LV longitudinal strain at baseline was significantly associated with a subsequent declined LVEF beneath 40%. Also, the lower strain a baseline implied the higher mortality and MACE. Using −12% as the cut-off value LV strain presented the most significant impact on the prognosis compared with the other echocardiographic parameters in the logistic regression Regarding the guideline directed medications, blockers of renin-angiotensin-aldosterone system most significantly improved the cardiac remodeling compared with the others. Conclusion STE can predict the subsequent changes of LVEF and the cardiovascular outcomes in patients with HFmrEF.
