Introduction: Reduced left ventricular (LV) global longitudinal strain (GLS) by two-dimensional speckle-tracking (2DST) echocardiography and late gadolinium enhancement (LGE) by cardiovascular magnetic resonance (CMR) have been reported to be associated with unfavorable outcome in patient with heart failure (HF). We investigated to assess these 2 markers as prognostic parameters over conventional HF markers in patients with dilated cardiomyopathy (DCM). METHODS: We studied consecutive 179 DCM patients (Age 61±15 years, 121 males, LV ejection fraction (LVEF) 33±9%, NYHA class I: n= 0; II: n=71; III: n=107; IV: n=1) who underwent CMR and echocardiography with conventional assessment including LV end-diastolic and end-systolic volume (LVEDV, LVESV), LVEF and mitral regurgitation grade (MR), and with 2DST analysis of GLS. Brain natriuretic peptide (BNP) was measured. Outcome was assessed according to death and hospitalization with heart failure in the follow-up period for 3.8±2.5 years. RESULTS: There were 7 cardiac deaths and 40 HF hospitalizations in the follow-up period. Univariate Cox proportional hazard regression analysis showed NYHA class, systolic blood pressure, diastolic blood pressure, BNP, LVEDV, LVESV, LVEF, MR, GLS and positive LGE were significantly associated with outcome. Multivariate Cox proportional hazards regression analysis revealed GLS and positive LGE (p<0.05 for both) were independent predictors of outcome. Dividing all 179 patients into 4 groups with the median of GLS (-8.3%) and the presence or absence of LGE, Kaplan-Meier analysis showed worse GLS predicted adverse events in patients with and without LGE (p<0.05 for both). GLS and LGE provide additional benefit over conventional parameters (Age, NYHA class, LVEF and BNP). CONCLUSIONS: Risk stratification with LGE and GLS is useful to predict long-term outcome in DCM patients. These 2 markers provide incremental prognostic value to conventional HF markers.

Abstract Cardiotoxicity is a frequent side effect of chemotherapy leading to impaired outcomes in cancer survivors. Because of that cardiooncology has recently gained more importance in clinical practice. We aim to echocardiographically evaluate the development of cardiotoxicity and to detect early signs for preventing severe cardiomyopathies by repeated strain analysis. We included 80 patients (46.7 ± 14.7 years, 75% female) under diverse cardiotoxic chemotherapies (43.7% breast cancer, 43.7% haematological malignancy, 12.5% others). All patients underwent echocardiography before and during treatment. Follow-up echocardiography was performed approximately 5.5 ± 1.2 months after the first application of the chemotherapy. The apical four-chamber view was used to perform strain analysis employing dedicated and automated offline software as shown previously. Eight patients deceased due to oncological complications during follow up. Twelve patients showed significant reduced left ventricle ejection fraction (LVEFbaseline 63.2 ± 4.5%, LVEFFollow-up 48.6 ± 7.8%, p = 0.02) correlated with decrease in left ventricular global longitudinal strain (LV-GLSbaseline 17.1 ± 5.2%, LV-GLSFollow-up 9.7 ± 3.2%, p = 001). All of these patients presented heart failure symptoms, mostly with dyspnoea (85% functional NYHA class &gt; II) and oedema (65%). In 15 patients we found a reduction of left ventricular global longitudinal strain from &lt;5% without relevant reduction of LVEF. However, these patients showed also heart failure symptoms. During follow up 20 patients had to be admitted due to decompensated heart failure. Four patients deceased due to cardiovascular causes. Delta LV-GLS (LV-GLSbaseline – LV-GLSFollow-up) was found to be strongest independent predictor of mortality. Baseline LV-GLS &lt; 15% was found to be associated with mortality and frequent rehospitalisation. Solely LVEF is insufficient to detect cardiotoxicity and to estimate prognosis of patients under cardiotoxic chemotherapy. In our small patient collective we found baseline LV-GLS &lt;15% to be an adequate parameter for prognosis estimation and delta LV-GLS &gt; 5% a strongest independent predictor for mortality in patients with preserved LVEF under cardiotoxic chemotherapy.

Abstract Purposes We examined how changes in left ventricular (LV) global longitudinal strain (GLS) were associated with prognosis in patients with preserved LV ejection fraction (LVEF) after congestive heart failure (HF) admission. Methods We studied 123 consecutive patients (age 70 ± 15 years, 55% male) who had been hospitalized due to congestive HF with preserved LVEF (&gt; 50%). The exclusion criteria were atrial fibrillation and inadequate echo image quality for strain analyses. The patients underwent speckle-tracking echocardiography and measurement of plasma NT-ProBNP levels on the same day at the time of hospital admission as well as in the stable condition after discharge. Differences in GLS, LVEF and NT-ProBNP (delta GLS, LVEF and NT-ProBNP ; 2nd – 1st measurements) were calculated. The study end points were all-cause mortality and cardiac events. Results Mean periods of echo performance after hospitalization were 2 ±1days (1st echo) and 240 ± 289 days (2nd echo), respectively. During the follow-up (974 ± 626 days), 12 patients died and 25 patients were hospitalized because of HF worsening. In multivariate analysis, delta GLS and follow-up GLS were prognostic factors, whereas baseline and follow-up LVEF, NT-ProBNP, changes in LVEF and NT-ProBNP could not predict cardiac events. Delta GLS (p = 0.002) turned out to be the best independent prognosticator. Receiver operating characteristics analysis revealed that -0.6% of delta GLS was the optimal cut-off value to predict cardiac events and mortality (sensitivity 76%, specificity 67%, AUC 0.75). Kaplan-Meier analysis showed that patients with delta GLS more than -0.6% experienced significantly less cardiac events during the follow-up period (p &lt; 0.0001, log-rank). Conclusion A change in LV GLS after congestive HF admission was a predictor of the prognosis in patients with preserved LVEF. It would be useful to check the changes in GLS in those with preserved LVEF after discharge.

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.

Abstract Background Congenital aortic stenosis (AoS) is associated with significant mortality and morbidity but predictors for clinical outcome are scarce. Strain analysis provides a robust and reproducible method for early detection of left ventricular (LV) dysfunction, which might be of prognostic value. Therefore we aimed to assess the prognostic value of LV global longitudinal strain (GLS) and global longitudinal early diastolic strain rate (GLSre) with regard to cardiovascular events. Methods This prospective study, included clinically stable patients with congenital AoS between 2011–2013. LV GLS and GLSre was performed in the apical 4, 3 and 2-chamber views using Tomtec software. The endpoint was a composite of death, heart failure, hospitalization, arrhythmia, thrombo-embolic events and re-intervention. Results In total 138 patients were included (33 [26–43] years, 86 (62%) male), NYHA class I: 134 (97%). Mean LV GLS was −15.3±3.2%, GLSre 0.66±0.18 s–1. Both correlated with NT-proBNP, LV volumes and ejection fraction (strongest LV GLS with LV EF: r −0.539, p<0.001, strongest LV GLSre with age: r −0.376 p<0.001). During median follow-up of 5.9 [5.5–6.2] years, the endpoint occurred in 53 (38%) patients: 4 patients died, 9 developed heart failure, 22 arrhythmias, 8 thrombo-embolic events and 35 re-interventions. Both LV GLS (standardized HR (sHR 0.62 (95% CI 0.47–0.81) and GLSre (sHR 0.62 (95% CI 0.47–0.83) were associated with the endpoint. Additional multivariable analysis showed that both GLS and GLSre were associated independent of left atrial volume, NT-proBNP and prior re-interventions. Figure 1 Conclusion Left ventricular GLS and GLSre are reduced in adult patients with congenital AoS. Both markers are associated with adverse cardiac events and have clear clinical relevance Acknowledgement/Funding Erasmus Thorax Foundation

Abstract Introduction Transcatheter aortic valve implantation (TAVI) can improve left ventricular (LV) mechanics and has been shown to improve long term survival. Data on the prognostic value of left atrial (LA) strain following TAVI are scarce. LA strain – a surrogate of LV filling pressure - can aid the early detection of diastolic dysfunction and correlates with the extent of fibrosis in atrial remodelling. Purpose In this multimodality study, we aimed to evaluate the prognostic value of LA function measured before hospital discharge following TAVI and to further elucidate its association with LV and LA reverse remodelling. Methods In this prospective single center study, we investigated 90 patients (mean age 78.5 years, 46.7% female) with severe, symptomatic aortic stenosis (AS) who underwent transthoracic echocardiography immediately after TAVI and 6 months later. LA and LV global longitudinal strain parameters were obtained by speckle tracking echocardiography. CT angiography (CTA) was performed for pre-TAVI planning and repeated at 6 months follow-up. LV mass values were derived from the serial CTA images. We defined LV reverse remodelling as reduction of myocardial mass quantified on CTA and as an improvement of LV global longitudinal strain (GLS). LA reverse remodelling was assessed based on the peak reservoir strain values (LAGS). The association of LA and LV global strain parameters, LA stiffness, systolic and diastolic functional parameters and LV mass based reverse remodelling were analysed using Pearson correlation coefficient and linear regression models. Results The mean LAGS and LVGLS values were 17.7% and 15.3% at discharge and 20.2% and 16.6% at follow-up, respectively (p=0.024, p&lt;0.001). LA and LV strain values improved in 60.6% and 74.5% of all patients. Reduced LAGS (&lt;20%) was found in 66.7% of all patients at baseline. LA strain at discharge correlated significantly with diastolic parameters (E wave, E/e', LAVI, all p&lt;0.05). Atrial reverse remodelling based on LAGS change correlated with LVGLS change (p&lt;0.01, standardized β=0.53) and LAGS at discharge (p=0.012, standardized β=−0.30). LAGS correlated with the extent of morphological LV remodelling based on LV mass reduction (p=0.002, coeff: 0.36). Elevated LA stiffness at discharge (upper tercile) leads to substantially lower LAGS at 6 months versus patients with lower LA stiffness value (1. and 2. tercile): 16.4±10.0 vs 21.9±9.8, p=0.042. Conclusion Patients with reduced LAGS immediately after TAVI showed a larger extent of LV reverse remodelling during follow up. On the other hand, increased LA stiffness at discharge was consistent with irreversible LA damage as demonstrated by a lack of improvement in LA function.

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 Background Mitral annular plane systolic excursion (MAPSE) derived from M-mode echocardiography is a classical risk factor of clinical outcome in heart failure patients. Two-dimensional-echocardiography (2DE) derived global longitudinal strain (GLS) is also related to outcome in patients with heart failure. This study aimed to compare the prognostic performance between GLS and MAPSE in ischemic heart failure patients with reduced ejection fraction. We sought to test the hypothesis that GLS might be superior to MAPSE as a risk stratification marker in these patients. Methods In total, 1277 ischemic heart failure patients with reduced left ventricular ejection fraction (LVEF&lt;50%), referred to our department between 2009 and 2017, were included in this retrospective study. Offline standard echocardiographic measurements including MAPSE and GLS were performed. Average MAPSE of septal and lateral walls (MAPSE_Avg) was calculated. GLS was derived from the segmental averaging (18-segment) of the three apical views. All patients completed at least one-year clinical follow-up by telephone interview or clinical visit. The primary endpoint was defined as all-cause mortality or heart transplantation (HTx). Results At baseline visit, mean age was 70±11 years and 79.6% were men. NYHA class III-IV were identified in 33.5% of patients. Coronary artery disease was confirmed by coronary angiography. 63.0% patients had a history of myocardial infarction, 32.1% underwent PCI, and 16.8% underwent coronary artery bypass grafting. Over a median follow-up period of 26 (14–39) months, 369 (28.9%) patients died and 5 (0.4%) underwent HTx. Median LVEF was 39% (32–45%), and there were 48.0% patients with LVEF between 40–49%, 32.3% patients with LVEF between 30–49% and 19.7% patients with LVEF &lt;30%. MAPSE_Avg was 8.0 (6.5–10.0) mm and median GLS was −9.9% (−7.7 to −12.3%). Clinical covariates significantly associated with all-cause mortality in this cohort included age (HR=1.048), NYHA class III-IV (HR=1.800), AF (HR=1.567), diabetes (HR=1.262), dyslipidemia (HR=0.657), hyperuricemia (HR=1.861), peripheral vascular disease (HR 1.858), chronic respiratory diseases (HR=1.680), and renal dysfunction (HR=2.705). Multivariable Cox regression analysis showed that reduced MAPSE_Avg (&lt;7mm, HR=1.431, 95% CI 1.146–1.786) and reduced GLS (&lt;8.3%, HR=1.519, 95% CI 1.230–1.875) were independent predictors of all-cause mortality after adjustment of above-mentioned clinical confounders. ROC curves demonstrated that the predictive performance of all-cause mortality among LVEF, MAPSE_Avg, and GLS were similar (AUC=0.608, 0.601, and 0.616, respectively, all P&lt;0.001). Conclusions Both 2DE-guided GLS and MAPSE could provide additional prognostic information in ischemic heart failure patients with reduced LVEF. Prognostic performance of GLS, MAPSE, and LVEF is similar in ischemic heart failure patients with reduced LVEF. Funding Acknowledgement Type of funding source: Public grant(s) – National budget only.

The main objective of this study was to model the left ventricle (LV) based on 2D echocardiography imaging technique to assess the cardiac mechanics for group of patients affected by heart failure. A prospective study has been made at Ibn Al-Bitar center for cardiac surgery, for 13 patients with heart failure (HF), 9 patients were males (69%) and 4 females (31%). The mean age was 54±7 years. Those patients were supposed to undergo a CRT-D (Cardiac Resynchronization Therapy Defibrillator) implant as they didn’t respond to drug therapy. Before CRT-D implantation, 2D echocardiography was performed for all the patients, to model the left ventricle and to measure indices that were used to evaluate cardiac mechanics which are LV pressure, wall stresses, global longitudinal strain, and cardiac output. After 3-months of follow-up, 2D echocardiography was re-assessed and the left ventricular mechanics has been re-measured. Post CRT-D implantation, significant improvement in the cardiac mechanics was observed in 54% of the patients which were called responders (patients that respond to CRT-D device) and the other patients were called non-responders. It has been seen that, the circumferential wall stresses were decreased in responder’s group while increased or remain unchanged in non-responders. Global longitudinal strain for the responder’s group were increased while remain unchanged in the non-responders. So, patients were divided into responders and non-responders, based on improvement of the cardiac mechanics after 3-moths of follow up. It has been concluded that the modelling of the left ventricle based on images obtained from 2D echocardiography imaging techniques, was an important computational tool that was used to enhance understanding and support the evaluation, surgical guidance and treatment management of basic biophysics underlying cardiac mechanics.
