Abstract Aims Non-invasive parameters used to assess right ventricular (RV) function, i.e. tricuspid annular plane systolic excursion (TAPSE), RV fractional area change (FAC), RV ejection fraction (RVEF), and RV free-wall longitudinal strain (RVFWLS) have shown their prognostic implications. However, since they are extremely load dependent, they do not provide an accurate representation of the RV intrinsic performance. On the other end, invasive indices of RV-arterial coupling (RVAC) derived from pressure–volume loops are not routinely performed, rising the urgency for more feasible, and reliable non-invasive estimates of RVAC. To (i) evaluate the prognostic value of echocardiography-derived RVAC surrogates: RVEF/sPAP, RVFWLS/sPAP, TAPSE/sPAP, FAC/sPAP, and RV stroke volume/end-systolic volume (SV/ESV); (ii) identify the cut-off values associated to all-cause mortality; and (iii) compare their prognostic value with that of classical parameters of RV function. Methods and results We prospectively enrolled 366 patients with various cardiac diseases, undergoing clinically indicated comprehensive two- and three-dimensional echocardiography. During a mean follow-up of 7.6 ± 1 years, 80 (21.9%) patients died. At univariable Cox regression, most of the echocardiographic parameters were related to all-cause mortality. The echocardiographic parameters with significance at univariable analysis (P < 0.01) were included in a multivariable regression model. Left ventricular ejection fraction (LVEF), RVEF, TAPSE, RVEF/sPAP, and RVFWLS/sPAP remained independently associated to all-cause mortality (P < 0.05 for all). Subsequently, they were tested in receiving operator characteristics (ROC) curves. At ROC analysis, RVEF/sPAP (area under the curve, AUC = 0.807, P < 0.001) and RVFWLS/sPAP (AUC = 0.743, P < 0.001) showed the greatest predictive value (P < 0.001 between them). However, all RV parameters significantly improved their values after indexing for sPAP (P < 0.01 for all). The best cut-offs to predict the outcome were 1.5 for RVEF/sPAP (specificity 71%, sensitivity 83%) and 0.67 for RVFWLS/sPAP (specificity 72%, sensitivity 68%). At Kaplan–Meier analysis, patients with reduced RVAC (less than the predefined cut-offs) had significantly lower probability of survival (P < 0.001 for all). Conclusions RVAC surrogates provide incremental prognostic value compared to standard RV functional measurements. RVEF/sPAP, with a cut-off value of 1.5, was the best parameter for risk stratification, and was independently related to all-cause mortality.

Echocardiographic Parameters

Abstract Background Novel echocardiographic software allows for layer-specific evaluation of myocardial deformation by 2-dimensional speckle tracking echocardiography. Endocardial, epicardial- and whole wall global longitudinal strain (GLS) may be superior to conventional echocardiographic parameters in predicting all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF). Purpose The purpose of this study was to investigate the prognostic value of endocardial-, epicardial- and whole wall GLS in patients with HFrEF in relation to all-cause mortality. Methods We included and analyzed transthoracic echocardiographic examinations from 1,015 patients with HFrEF. The echocardiographic images were analyzed, and conventional and novel echocardiographic parameters were obtained. A p value in a 2-sided test <0.05 was considered statistically significant. Cox proportional hazards regression models were constructed, and both univariable and multivariable hazard ratios (HRs) were calculated. Results During a median follow-up time of 40 months, 171 patients (16.8%) died. A lower endocardial (HR 1.17; 95% CI (1.11–1.23), per 1% decrease, p<0.001), epicardial (HR 1.20; 95% CI (1.13–1.27), per 1% decrease, p<0.001), and whole wall (HR 1.20; 95% CI (1.14–1.27), per 1% decrease, p<0.001) GLS were all associated with higher risk of death (Figure 1). Both endocardial (HR 1.12; 95% CI (1.01–1.23), p=0.027), epicardial (HR 1.13; 95% CI (1.01–1.26), p=0.040) and whole wall (HR 1.13; 95% CI (1.01–1.27), p=0.030) GLS remained independent predictors of mortality in the multivariable models after adjusting for significant clinical parameters (age, sex, total cholesterol, mean arterial pressure, heart rate, ischemic cardiomyopathy, percutaneous transluminal coronary angioplasty and diabetes) and conventional echocardiographic parameters (left ventricular (LV) ejection fraction, LV mass index, left atrial volume index, deceleration time, E/e', E-velocity, E/A ratio and tricuspid annular plane systolic excursion). No other echocardiographic parameters remained an independent predictors after adjusting. Furthermore, endocardial, epicardial and whole wall GLS had the highest C-statistics of all the echocardiographic parameters. Conclusion Endocardial, epicardial and whole wall GLS are independent predictors of all-cause mortality in patients with HFrEF. Furthermore, endocardial, epicardial and whole wall GLS were superior prognosticators of all-cause mortality compared with all other echocardiographic parameters.

Abstract Background Early systolic lengthening (ESL) and postsystolic shortening are considered highly specific for myocardial ischemia. We aimed to investigate the prognostic potential of both deformational patterns in patients with heart failure (HF) and to determine if a history of ischemic heart disease modified this relationship. Method A total of 884 patients with systolic HF (66±12 years, male 73%, mean ejection fraction 28±9%) underwent speckle tracking echocardiography. Of these, 61% suffered from ischemic cardiomyopathy (ICM). Patients were followed for all-cause mortality. We assessed the ESL index: [−100x (peak positive strain/maximal strain)] and the postsystolic index (PSI): [100x (postsystolic strain/maximal strain)]. Both parameters were averaged across 18 myocardial segments. Results During a median follow-up of 3.4 years [interquartile range 1.9 to 4.8], 132 patients (15%) died. In multivariable survival analyses adjusted for potential confounders (age, sex, BMI, mean arterial pressure, cholesterol, heart rate, CABG/PCI, left ventricular ejection fraction and mass index, left atrial volume index, tricuspid annular plane systolic excursion, E-wave, E/e', deceleration time, and global longitudinal strain) neither the ESL index (HR 1.02 per 1% increase [0.97 to 1.08], P=0.40) nor PSI (HR 1.00 per 1% increase [0.98 to 1.01], P=0.69) were associated with all-cause mortality. ICM modified the relationship (P interaction unadjusted/adjusted=0.001/0.008; Figure) such that per 1% increase in ESL index in patients with ICM was significantly associated with all-cause mortality (unadjusted: HR 1.09 [1.04 to 1.15], P<0.001 and adjusted: HR 1.06 [1.00 to 1.13], P=0.045) but not in those without (unadjusted: HR 1.02 [1.01 to 1.03], P=0.002 and adjusted: HR 0.99 [0.90 to 1.09], P=0.086). ICM did not modify the relationship between PSI and all-cause mortality (P interaction unadjusted/adjusted=0.15/0.13). Conclusion Our results indicate that in this cohort of undifferentiated HF patients with reduced ejection fraction the prognostic value of deformational patterns was reduced. However, the ESL index may provide some information on prognosis in patients with ICM. ESL and interaction with ICM Funding Acknowledgement Type of funding source: None

Abstract BACKGROUND Simple and reproducible echocardiographic parameters are still the cornerstone of daily clinical practice. These data provides important information for the evaluation of patients with ST-segment elevation myocardial infarction (STEMI). The identification of prognostic echocardiographic parameters in STEMI would help in risk stratification. PURPOSE To evaluate the discriminatory capacity of echocardiographic parameters after a STEMI. METHODS Single centre retrospective observational study of 303 patients with STEMI who survived hospital stay and had a complete echocardiographic evaluation. The following ecocardiographic parameters were collected at discharge: left ventricular (LV) systolic and diastolic volumes; septal and posterior wall thickness; LV ejection fraction (LVEF); left atrial (LA) diameter; estimated systolic pulmonary artery pressure (SPAP). One year and long-term all cause mortality were analyzed. RESULTS For the patients enrolled (71% males, 64.6 ± 14.1 years old), peak troponin I was 99.1 ± 126.5 ng/mL; mean GRACE score was 153.6 ± 38.8 points and mean LVEF was 46.2 ± 11.2%. One year mortality was 8.3% and during a median 73 months follow-up, 25.1% patients were deceased. After adjustment for echocardiographic variables in a Cox regression model, SPAP (HR 1.07, 95%CI 1.02-1.12, P = 0.007) and septal thickness (HR 1.36, 95%CI 1.08-1.73, P = 0.01) were both independently associated with one year mortality. A Kaplan-Meier survival methodology using stratified SPAP and septal thickness showed a trend of different event rate (log rank P = 0.003 and P = 0.035, respectively), with a gradation of cumulative risk for all-cause mortality, with a sharp increase at >40mmHg and >11mm, respectively. Regarding longterm follow-up, only increased SPAP proved to be an independent predictor of mortality (HR 1.04, 95%CI 1.01-1.08, P = 0.016). The difference in favor of an SPAP <33mmHg (sensitivity 86.67% and specificity 54.1%) was seen early after the STEMI event and maintained at each interim analysis (log rank P = 0.002). Upon the visual analysis of the cubic spline curves, patients with SPAP < ± 30mmHg had a good long-term survival. No association of LV volumes or LVEF was noted for both one year and long-term mortality. CONCLUSION Classic echocardiographic parameters still have a role to estimate prognosis after STEMI. Estimated SPAP had the greatest discriminatory capabilities, surpassing left ventricular ejection fraction! Abstract 571 FIGURE 1

Baseline Characteristics

ObjectivesThe aim of this study was to analyse baseline characteristics and outcome of patients with heart failure and mid-range left ventricular ejection fraction (HFmrEF, left ventricular ejection fraction (LVEF) 40%–49%) and the effect of 1-year change in LVEF in this group.SettingMulticentre prospective observational study of ambulatory patients with HF followed up at four university hospitals with dedicated HF units.ParticipantsFourteen per cent (n=504) of the 3580 patients included had HFmrEF.InterventionsBaseline characteristics, 1-year LVEF and outcomes were collected. All-cause death, HF hospitalisation and the composite end-point were the primary outcomes.ResultsMedian follow-up was 3.66 (1.69–6.04) years. All-cause death, HF hospitalisation and the composite end-point were 47%, 35% and 59%, respectively. Outcomes were worse in HF with preserved ejection fraction (HFpEF) (LVEF>50%), without differences between HF with reduced ejection fraction (HFrEF) (LVEF<40%) and HFmrEF (all-cause mortality 52.6% vs 45.8% and 43.8%, respectively, P=0.001). After multivariable Cox regression analyses, no differences in all-cause death and the composite end-point were seen between the three groups. HF hospitalisation and cardiovascular death were not statistically different between patients with HFmrEF and HFrEF. At 1-year follow-up, 62% of patients with HFmrEF had LVEF measured: 24% had LVEF<40%, 43% maintained LVEF 40%–49% and 33% had LVEF>50%. While change in LVEF as continuous variable was not associated with better outcomes, those patients who evolved from HFmrEF to HFpEF did have a better outcome. Those who remained in the HFmrEF and HFrEF groups had higher all-cause mortality after adjustment for age, sex and baseline LVEF (HR 1.96 (95% CI 1.08 to 3.54, P=0.027) and HR 2.01 (95% CI 1.04 to 3.86, P=0.037), respectively).ConclusionsPatients with HFmrEF have a clinical profile in-between HFpEF and HFrEF, without differences in all-cause mortality and the composite end-point between the three groups. At 1 year, patients with HFmrEF exhibited the greatest variability in LVEF and this change was associated with survival.

Abstract Background Heart failure with mid-range ejection fraction (left ventricular ejection fraction between 40 to 49%) was introduced in the 2016 European Society of Cardiology guidelines for heart failure. The prognosis of the mid-range of left ventricular ejection fraction (LVEF) was less well assessed in patients treated with percutaneous coronary intervention (PCI). Purpose We aimed to assess the 2-year outcomes of patients with mid-range ejection fraction (LVEF between 40 to 49%) after PCI compared with reduced LVEF (<40%) and preserved LVEF (≥50) in the GLOBAL LEADERS study. Methods The GLOBAL LEADERS study was a multicenter, randomized trial comparing the efficacy and safety of two antiplatelet strategies in all-comers patients undergoing PCI with biolimus-A9 eluting stent. Patients with available information of LVEF were eligible in the present analysis. Patients were classified according to their LVEF into three groups; preserved (LVEF ≥50), mid-range (LVEF 40–49%) and reduced (LVEF <40%) left ventricular ejection fraction. Clinical outcomes at 2 years after PCI were compared among three groups in the multivariable Cox regression analysis. The primary outcome of present study was all-cause mortality at 2 years after PCI. The secondary outcomes were patient-oriented composite endpoint (POCE). Individual components of the composite endpoint, definite or probable stent thrombosis and bleeding academic research consortium (BARC) type 3 or 5 were also reported. Results Out of 15968 patients included in the GLOBAL LEADERS study, information of LVEF was available in 15008 patients (93.99%); 12,128 patients (80.81%) were in the group of preserved LVEF, 1,737 patients (11.57%) were in the mid-range LVEF group and 1,143 patients (7.62%) were in the reduced LVEF group. The risk of all-cause mortality and POCE at 2 years were significantly different among the three groups. In an adjusted model, compared with the group of preserved LVEF, the hazard ratio for the all-cause mortality at 2 years rose from 1.89 (95% CI, 1.46–2.45) to 3.72 (95% CI, 2.95–4.70) in the group of mid-range and reduced LVEF respectively. Similar rises were observed for the POCE at 2 years from 1.27 (95% CI, 1.11–1.44) in the group of mid-range LVEF to 1.63 (95% CI, 1.42–1.87) in the group of reduced LVEF. The risk of stroke, myocardial infarction, and definite or probable stent thrombosis in patients with mid-range LVEF was not different from patients with reduced LVEF (see figure). A similar risk of revascularization was observed among the three groups. Outcomes among three LVEF categories Conclusion Patients with mid-range LVEF undergoing PCI had a different prognosis from patients with reduced LVEF and preserved LVEF in term of survival and composite ischemic endpoints at 2 years.

Abstract Background/Introduction Previous studies have focused on only 1 or 2 echocardiographic parameters as prognostic marker in patients with acute ischemic stroke (AIS). Purpose Various echocardiographic parameters in the same patient were systemically evaluated for their prognostic significance in AIS. Methods A total of 900 patients with AIS who underwent transthoracic echocardiography (TTE) (72.6 ± 12.0 years and 60% male) were retrospectively reviewed. Composite events including all-cause mortality, non-fatal stroke, non-fatal myocardial infarction, and coronary revascularization were assessed during clinical follow-up. Results During a median follow-up of 3.3 years (interquartile range, 0.6-5.1 years), there were 151 (16.8%) composite events. Univariable analyses showed that low left ventricular ejection fraction (LVEF) (&lt; 60%), increased peak tricuspid regurgitation (TR) velocity (&gt; 2.8 m/s) and aortic valve (AV) sclerosis were associated with composite events (P &lt; 0.05 for each). In the multivariable analyses after controlling for potential confounders, LVEF &lt; 60% (hazard ratio [HR], 1.90; 95% confidence interval [CI], 1.30-2.77; P = 0.001) and AV sclerosis (HR, 1.56; 95% CI, 1.10-2.21; P = 0.013) were independent prognostic factors associated with composite events. Multivariable analysis showed that HR for composite events gradually increased according to LVEF and AV sclerosis: HR was 2.8-fold higher in the highest-risk group than in the lowest group (P = 0.001). Conclusions In patients with AIS, LVEF &lt; 60% and the presence of AV sclerosis predicts the future vascular events. Patients with AIS exhibiting reduced LVEF and AV sclerosis may benefit from aggressive secondary prevention Abstract P1348 Figure. COX plot for composite event

BackgroundIt has been reported that recovery of left ventricular ejection fraction (LVEF) is associated with better prognosis in heart failure (HF) patients with reduced EF (rEF). However, change of LVEF has not yet been investigated in cases of HF with preserved EF (HFpEF).Methods and resultsConsecutive 1082 HFpEF patients, who had been admitted to hospital due to decompensated HF (EF >50% at the first LVEF assessment at discharge), were enrolled, and LVEF was reassessed within 6 months in the outpatient setting (second LVEF assessment). Among the HFpEF patients, LVEF of 758 patients remained above 50% (pEF group), 138 patients had LVEF of 40%–49% (midrange EF, mrEF group) and 186 patients had LVEF of less than 40% (rEF group). In the multivariable logistic regression analysis, younger age and presence of higher levels of troponin I were predictors of rEF (worsened HFpEF). In the Kaplan-Meier analysis, the cardiac event rate of the groups progressively increased from pEF, mrEF to rEF (log-rank, p<0.001), whereas all-cause mortality did not significantly differ among the groups. In the multivariable Cox proportional hazard analysis, rEF (vs pEF) was not a predictor of all-cause mortality, but an independent predictor of increased cardiac event rates (HR 1.424, 95% CI 1.020 to 1.861, p=0.039).ConclusionAn initial assessment of LVEF and LVEF changes are important for deciding treatment and predicting prognosis in HFpEF patients. In addition, several confounding factors are associated with LVEF changes in worsened HFpEF patients.
