Abstract Aims In acute and chronic heart failure (HF), the relief of congestion is one of the pivotal elements to improve patient’s quality of life and prognosis. N-terminal pro-brain natriuretic peptide (NT-proBNP) is a well-known marker of cardiovascular (CV) congestion in HF, although with limited specificity. Peak atrial longitudinal strain (PALS) by speckle tracking echocardiography is emerging as an index of left ventricular (LV) filling pressure and prognosis in HF, however, its role as a marker of congestion should be further elucidated. The aim of our study was to determine the association between NT-proBNP and PALS in patients acute and chronic HF. Methods and results Patients hospitalized for de-novo or recurrent acute HF and patients with chronic HF referred to our echo-labs for follow-up evaluation were included in this retrospective study. Patients with missing data, previous cardiac surgery, heart transplant and/or left ventricular assist device implantation, non-feasible speckle tracking analysis were excluded. Clinical characteristics, laboratory examinations, transthoracic echocardiography data were collected. Speckle tracking analysis was performed offline on the echocardiographic records. Follow up data were obtained via electronical records or phone-calls. The primary clinical endpoint was a combination of all-cause death and HF hospitalization. The overall study cohort included 388 patients (172 with chronic HF and 216 with chronic HF). Mean age was 65 ± 12, 37% were female. Most patients had reduced LV systolic function (mean LV ejection fraction = 30 ± 10%; mean LV global longitudinal strain = −8.3 ± 3.9%). Patients with acute HF presented higher values of NT-proBNP than those with chronic HF [median (interquartile range) = 6039 (2989–13 535) pg/ml vs. 544 (200–1533) pg/ml] and lower global PALS =10.4 (6.3–16.45)% vs. 15.6 (10.6–21)%. Global PALS showed a significant inverse correlation with NT-proBNP both in acute and chronic HF (all P < 0.001) and to be a significant predictor of NT-proBNP with linear regression analysis (R2 = 0.2; P < 0.001). During a median follow-up of 1 year, 98 patients reached the combined endpoint (49 all-cause deaths, 16 CV deaths, 62 HF hospitalizations). With ROC curves, both NT-proBNP and global PALS showed to be good predictors of the combined endpoint (AUC = 0.87and 0.82, respectively, Figure 1). Conclusions Global PALS is associated with NT-proBNP in acute and chronic HF and may be used as additional index of congestion to optimize therapeutic management in these patients. Both global PALS and NT-proBNP confirmed to be accurate prognostic markers in HF.

Abstract Background In chronic heart failure (CHF) NT-proBNP and left ventricular ejection fraction (LVEF) by echocardiography are standard diagnostic as well as follow-up markers and are known to correlate with prognosis. Speckle-tracking echocardiography is a more recent technique to quantify myocardial deformation as a measurement of left ventricular function with potential benefits over LVEF. Purpose The purpose of this investigation was to analyse the cross-sectional relationship between 2D speckle tracking-derived global longitudinal strain (GLS) and NT-proBNP plasma levels in a prospective cohort of ischemic and non-ischemic CHF patients. Methods We enrolled 205 patients with chronic heart failure. Major inclusion criteria were age over 18 years, stable disease with absence of unplanned hospitalization or change in medication or device therapy in the previous month or major surgery in the previous 3 months. CHF treatment had to be according to the recommendations of the ESC CHF guidelines 2016 and LVEF had to be below 50%. Patient history, physical examination and an extensive echocardiography exam were performed. Lab results included NT-proBNP. Manual longitudinal strain was calculated using EchoPAC (General Electric Medical Systems, Horten, Norway) by a single and blinded examiner. LVEF was measured using Simpson's biplane method. Results 205 patients included in the study. The baseline characteristics included mean age 65.0 years and 75% male. Mean GLS was −9.6% (SD ±4.5%) and median NT-proBNP 1269.5 (IQR 379.5–2759.5) ng/ml. The CHF aetiology was 70.0% ischemic vs 30.0% non-ischemic. There was a significant negative correlation between GLS and NT-proBNP (Pearson r=0.239, p=0.029), this was not significant for LVEF and NT-proBNP (Pearson r=0.149, p=0.228).In a multivariate regression analysis adjusted for age, sex, NYHA classification and HF aetiology, GLS remained significantly correlated with NT-proBNP (adjusted beta-coefficient= 0.289, p=0.011). Furthermore, in contrast to LVEF, GLS showed a significant correlation to NT-proBNP in patients with ischemic (Pearson r=0.266, p=0.049) as well as non-ischemic aetiology of heart failure (Pearson r=0.434, p=0.034). Conclusion Global longitudinal strain, not LVEF, was significantly correlated with NT-proBNP in patients with CHF, independently of age, sex, symptoms or heart failure aetiology. This shows that speckle-tracking might be superior to LVEF for the assessment of left ventricular function in CHF.

Abstract Background Atrial fibrillation (AF) impairs mechanical function of the heart, especially atria and restoration of sinus rhythm (SR) leads to improvement of mechanics. The predicting role of changes in strain parameters for AF recurrence is not established yet. Purpose To analyse changes in left atrial (LA) and left ventricular (LV) mechanical function after conversion to SR and their prognostic values for AF recurrence during 24 months follow-up. Methods Prospective study involved 59 patients after successful electrical cardioversion (EC) because of nonvalvular AF (mean age 65±4 years, 47% female). Speckle tracking analysis (STE) was applied to calculate longitudinal strain of LV and LA before EC and within 24 hours after restoration of SR and additionally total left heart strain (TS) defined as a sum of absolute peak LV and LA strain. We calculated change in strain between AF and SR analyses expressed as delta (Δ). During follow-up we noticed AF recurrence in 42 (71%) patients, most of them (93%) during 1st year after EC. Median time of AF recurrence was 3 months. Results We noticed significant immediate post-EC improvement in peak LA longitudinal strain (PALS) and LV global longitudinal strain (LVGLS) (table). Unlike CHA2DS2-VASc score, strain parameters were predictors of AF recurrence. Every 1% increment in ΔLVGLS was related with 13% increase in AF recurrence risk (p=0.02) and every 1% increment in ΔPALS and ΔTS were related with 9% decrease in AF recurrence risk (p=0.007 and p=0.0014, respectively). Multivariate analysis revealed ΔTS as a strongest predictor with 9% decrease in AF risk per every 1% increment. The criterion of ΔTS ≤7.5% allows to predict AF recurrence with 81% sensitivity and 63% specificity. Conclusions Speckle tracking measurements are able to detect early mechanical changes in LA even within 24 hours of SR and these absolute changes in LVGLS as well as PALS can predict AF recurrence, with optimal stratification by novel parameter - TS.

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 (> 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 < 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.

<p><strong>Aim</strong>. Rheumatoid arthritis (RA) shows a high risk for cardiovascular disease, including heart failure. Although TNF-α has been implicated in the pathogenesis of myocardial remodelling, TNF-α inhibition did not show any efficacy in patients with advanced heart failure and should be contraindicated in RA with cardiac complications. We aimed to assess global left ventricular (LV) systolic function using global longitudinal strain (GLS) as a measure of myocardial deformation, in a group of RA patients before and during anti-TNF-α treatment. <strong>Methods</strong>. 13 patients (female:male 7:6) affected by RA were prospectively followed for one year during anti TNF-α treatment. Every subject underwent echocardiography before starting anti-TNF-α drugs and after one year of treatment, to evaluate LV ejection fraction (EF), telediastolic diameter, telediastolic volume and global longitudinal strain (GLS) that was calculated using 2D speckle tracking as the mean GLS from three standard apical views (2, 3 and 4 -chambers). The patients showed a mean age of 43 years at RA onset (SD: 13) and a mean follow-up of 7.3 years (SD: 4.8). Steroid and methotrexate were used in 84.6% and 100%, respectively, in association with etanercept (6 cases), adalimumab (4 cases) and infliximab (3 cases). <strong>Results</strong>. Patients globally showed a normal EF before and after one year of treatment (mean: 65% and 65.7%, respectively). GLS did not differ before or after anti-TNF-α treatment (mean: -15.8% and -16.7%, respectively). <strong>Conclusion</strong>. Anti-TNF-α treatment did not significantly modify myocardial contractility after 12 months.</p><p> </p><p> </p>

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.

An increasing number of two- and three-dimensional echocardiographic, Doppler, and speckle imaging-derived parameters and values can be related to prognosis in heart failure with left ventricular (LV) systolic dysfunction. This chapter discusses both conventional and new indices, including their advantages and potential limitations. There is increasing evidence for the use of new indices, including three-dimensional LV ejection fraction and global longitudinal strain. The follow-up and monitoring of heart failure patients using two-dimensional transthoracic echocardiography is also discussed in this chapter, including how to estimate the LV filling pressures and quantify LV reverse remodelling.

Reduced Ejection Fraction

Sacubitril/valsartan reduces mortality in heart failure with reduced ejection fraction (HFrEF) patients, partially due to cardiac reverse remodeling (RR). Little is known about the RR rate in long-lasting HFrEF and the evolution of advanced echocardiographic parameters, despite their known prognostic impact in this setting. We sought to evaluate the rates of left ventricle (LV) and left atrial (LA) RR through standard and advanced echocardiographic imaging in a cohort of HFrEF patients, after the introduction of sacubitril/valsartan. A multi-parametric standard and advanced echocardiographic evaluation was performed at the moment of introduction of sacubitril/valsartan and at 3 to 18 months subsequent follow-up. LVRR was defined as an increase in the LV ejection fraction ≥10 points associated with a decrease ≥10% in indexed LV end-diastolic diameter; LARR was defined as a decrease >15% in the left atrium end-systolic volume. We analyzed 77 patients (65 ± 11 years old, 78% males, 40% ischemic etiology) with 76 (28–165) months since HFrEF diagnosis. After a median follow-up of 9 (interquartile range 6–14) months from the beginning of sacubitril/valsartan, LVRR occurred in 20 patients (26%) and LARR in 33 patients (43%). Moreover, left ventricular global longitudinal strain (LVGLS) improved from −8.3 ± 4% to −12 ± 4.7% (p < 0.001), total left atrial emptying fraction (TLAEF) from 28.2 ± 14.4% to 32.6 ± 13.7% (p = 0.01) and peak atrial longitudinal strain (PALS) from 10.3 ± 6.9% to 13.7 ± 7.6% (p < 0.001). In HFrEF patients, despite a long history of the disease, the introduction of sacubitril/valsartan provides a rapid global (i.e., LV and LA) RR in >25% of cases, both at standard and advanced echocardiographic evaluations.

Speckle tracking echocardiography enables the detection of subclinical left ventricular dysfunction at rest in many heart diseases and potentially in severe liver diseases. It could also possibly serve as a predictor for survival. In this study, 117 patients evaluated for liver transplantation in a single center between May 2010 and April 2016 with normal left ventricular ejection fraction were included according to clinical characteristics of their liver disease: (1) compensated (n = 29), (2) clinically significant portal hypertension (n = 49), and (3) decompensated (n = 39). Standard echocardiography and speckle tracking echocardiography were performed at rest and during dobutamine stress. Follow-up amounted to three years to evaluate survival and major cardiac events. Altogether 67% (78/117) of the patients were transplanted and 32% (31/96 patients) died during the three-year follow-up period. Global longitudinal strain (GLS) at rest was significantly increased (became more negative) with the severity of liver disease (p < 0.001), but reached comparable values in all groups during peak stress. Low (less negative) GLS values at rest (male: >−17/female: >−18%) could predict patient survival in a multivariate Cox regression analysis (p = 0.002). GLS proved valuable in identifying transplant candidates with latent systolic dysfunction.

Incremental Prognostic Value

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.
