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

Worse Prognosis

AbstractBoth acute myocardial infarction complicated by ventricular tachyarrhythmias (AMI–VTA) and electrical storm (ES) represent life-threatening clinical conditions. However, a direct comparison of both sub-groups regarding prognostic endpoints has never been investigated. All consecutive implantable cardioverter-defibrillator (ICD) recipients were included retrospectively from 2002 to 2016. Patients with ES apart from AMI (ES) were compared to patients with AMI accompanied by ventricular tachyarrhythmias (AMI–VTA). The primary endpoint was all-cause mortality at 3 years, secondary endpoints were in-hospital mortality, rehospitalization rates and major adverse cardiac event (MACE) at 3 years. A total of 198 consecutive ICD recipients were included (AMI–VTA: 56%; ST-segment elevation myocardial infarction (STEMI): 22%; non-ST-segment myocardial infarction (NSTEMI) 78%; ES: 44%). ES patients were older and had higher rates of severely reduced left ventricular ejection fraction (LVEF) < 35%. ES was associated with increased all-cause mortality at 3 years (37% vs. 19%; p = 0.001; hazard ratio [HR] = 2.242; 95% CI 2.291–3.894; p = 0.004) and with increased risk of first cardiac rehospitalization (44% vs. 12%; p = 0.001; HR = 4.694; 95% CI 2.498–8.823; p = 0.001). This worse prognosis of ES compared to AMI–VTA was still evident after multivariable adjustment (long-term all-cause mortality: HR = 2.504; 95% CI 1.093–5.739; p = 0.030; first cardiac rehospitalization: HR = 2.887; 95% CI 1.240–6.720; p = 0.014). In contrast, the rates of MACE (40% vs. 32%; p = 0.326) were comparable in both groups. At long-term follow-up of 3 years, ES was associated with higher rates of all-cause mortality and rehospitalization compared to patients with AMI–VTA.

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 Despite optimal medical and surgical treatment, mortality in infective endocarditis (IE) remains high. Aim of this study was to identify predictors of long term mortality for any cause, adverse event rate, relapse rate and valvular dysfunction at follow-up, in a high-volume surgical center. Methods We retrospectively analyzed 358 consecutive patients (127 women) admitted to our department with definite diagnosis of IE not device-related. IE occurred on native valves in 224 patients (63%); the infection involved the aortic valve in 192 (54%), mitral valve in 139 (39%) and tricuspid valve in 26 (7%). Overall 285 (80%) patients underwent surgery and 73 (20%) were treated conservatively, 38 due to absence of surgical indication and 35 due to refusal or prohibitive surgical risk. Long-term follow-up was obtained by structured telephone interviews. Primary endpoints were all-cause mortality, freedom from recurrent endocarditis, postoperative incidence of major adverse events (hospitalization for any cause, pace-maker implantation, new onset of atrial fibrillation, sternal dehiscence), worsening of left ventricular ejection fraction (LVEF) and valvular dysfunction. Results Mean age was 65 years (SD 15.2). Mean vegetation length was 8.9 mm (SD 7.6). Endocarditis was left-sided in 332 (93%). Average follow-up was 6 months. At univariable analysis, mortality was associated with female gender (p=0.031), age (p&lt;0.001), higher EuroSCORE 2 (p&lt;0.001), chronic renal failure (p&lt;0.001), diabetes (p=0.002), brain embolism on presentation (p=0.05), double valve infection (p=0.008), low ejection fraction (p&lt;0.001), paravalvular extension (p=0.031), prosthetic infection (p=0.018), exclusion from surgery if indicated (p&lt;0.001), high procalcitonin levels (p=0.035); factors associated with a significantly lower mortality were streptococcal infection (p=0.04; OR 0.34) and early surgery (p=0.009, OR 0.55). At multivariable analysis independent predictors of all-cause mortality were lower EF, EuroSCORE2, procalcitonin levels and diabetes. Non-fatal adverse events were associated with renal failure (p 0.035, OR 2.8). Relapse rate was associated with S aureus infection (p=0.005, OR 3.8), right-sided endocarditis (p&lt;0.001, OR 6.7) and drug abuse (p&lt;0.001, OR 9.4). Conclusions The present study shows that low EF, EuroSCORE2, procalcitonin levels and diabetes are independent predictors of death in patients with IE. Non-fatal adverse events are more frequent in patients with renal failure. Relapse rate is higher in drug abusers. These informations may help personalize follow-up strategies after acute admission for IE. Funding Acknowledgement Type of funding source: None

The Impact

Background: The angiotensin receptor-neprilysin inhibitor (ARNI) decreases cardiovascular mortality in patients with chronic heart failure with a reduced ejection fraction (HFrEF). Data regarding the impact of ARNI on the outcome in HFrEF patients according to heart failure etiology are limited. Methods and results: One hundred twenty-one consecutive patients with HFrEF from the years 2016 to 2017 were included at the Medical Centre Mannheim Heidelberg University and treated with ARNI according to the current guidelines. Left ventricular ejection fraction (LVEF) was numerically improved during the treatment with ARNI in both patient groups, that with ischemic cardiomyopathy (n = 61) (ICMP), and that with non-ischemic cardiomyopathy (n = 60) (NICMP); p = 0.25. Consistent with this data, the NT-proBNP decreased in both groups, more commonly in the NICMP patient group. In addition, the glomerular filtration rate (GFR) and creatinine changed before and after the treatment with ARNI in both groups. In a one-year follow-up, the rate of ventricular tachyarrhythmias (ventricular tachycardia and ventricular fibrillation) tended to be higher in the ICMP group compared with the NICMP group (ICMP 38.71% vs. NICMP 17.24%; p = 0.07). The rate of one-year all-cause mortality was similar in both groups (ICMP 6.5% vs. NICMP 6.6%; log-rank = 0.9947). Conclusions: This study shows that, although the treatment with ARNI improves the LVEF in ICMP and NICMP patients, the risk of ventricular tachyarrhythmias remains higher in ICMP patients in comparison with NICMP patients. Renal function is improved in the NICMP group after the treatment. Long-term mortality is similar over a one-year follow-up.

Significant Difference

Background: Relatively high left ventricular ejection fraction (EF) (>65%) in women was recently associated with higher all-cause mortality over 6 years follow-up in the CONFIRM study. We sought to evaluate high EF and major adverse cardiovascular events (MACE) in the Women’s Ischemia Syndrome Evaluation (WISE) study. Methods: The WISE original cohort (enrolled 1996-2000) is a multicenter prospective study of women with suspected ischemic heart disease undergoing clinically indicated invasive coronary angiography. We investigated the relationship between high (>65%) and normal (55-65%) EF and MACE, defined as all-cause death, nonfatal myocardial infarction (MI), stroke and heart failure (HF) hospitalization using Kaplan Meier (KM) and regression analyses. Results: A total of 653 women were included (298 high and 355 normal EF). Mean age was 58±11 years and mean EF was 68±7%. There was no significant difference in MACE by EF group over a 10-year follow-up period (log rank p=0.54, Figure ). When patients were stratified by the presence of obstructive CAD, MACE rates remained similar between high and normal EF. High EF was not associated with stroke or HF but had a lower MI risk (log rank p=0.03, Table ). EF was not associated with MACE in a multivariable regression model. Conclusions: Among women presenting with evidence of ischemia, there was no significant difference in MACE between high and normal EF groups. High EF was associated with a lower risk of myocardial infarction as an individual component of MACE.

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

Abstract Introduction The CARISMA trial was the first study to use continuous monitoring for documentation of long-term arrhythmias in post-infarction patients with left ventricular dysfunction. During the study duration (2000–2005), primary PCI (pPCI) as treatment of acute myocardial infarction was introduced approximately midway (2002) on the enrolling centres. Purpose The aim of this study was to describe the influence of mode of revascularization after myocardial infarction (AMI) on long-term risk of risk of new onset atrial fibrillation, ventricular tachyarrhythmias and brady arrhythmias. Methods The study is a sub-study on the CARISMA study population that consisted of patients with AMI and left ventricular ejection fraction ≤40%, which received an implantable loop recorder and was followed for 2 years. After exclusion of 15 patients who refused device implantation and 26 with pre-existing arrhythmias, 268 of the 312 patients were included. Choice of revascularization was made by the treating team independently of the trial and was retrospectively divided into primary percutaneous intervention (pPCI), subacute PCI (24 hours to 2 weeks after AMI), primary thrombolysis or no revascularization. Endpoints were new-onset of arrhythmias and major cardiovascular events (MACE). The Kaplan-Meier (figure 1) and Mantel-Byar methods were used for time to first event risk analysis. Results A total of 77 patients received no revascularization, whereas 49 received thrombolysis only and 142 received PCI. At two-years follow up patients treated with any PCI had a significant lower risk (0.40, n=63) of any arrhythmia compared to patients treated with trombolysis (0.60, n=30) or no revascularization (0.68, n=16) (p<0.001, unadjusted) (figure 1). Risk of MACE was significant higher in patients with any arrhythmia (0.25, n=76) compared to no arrhythmia (0.11, n=93) at two years follow-up (p=0.004, unadjusted). Figure 1 Conclusion(s) The long-term risk of new onset arrhythmias after AMI was significantly lower in patients treated with any PCI compared to patients not revascularized or treated with thrombolysis. Risk of MACE was significantly higher in patients with new onset arrhythmias compared to patients with no arrhythmias.

Abstract Background The occurrence of HF (heart failure) with preserved ejection fraction (HFpEF) has risen significantly over the past decade. Galectin-3 (Gal-3) and soluble ST2 (sST2) are involved in inflammatory processes and fibrosis and might be useful in estimation of the risk of HFpEF development after myocardial infarction (MI).Purpose: To investigate the association of Gal-3 and sST2, and their follow-up changeswith echocardiographic parameters of systolic and diastolic dysfunctionin patients (pts) with ST-segment elevation MI (STEMI) treated with primary percutaneous coronary intervention (pPCI). Methods:A prospective, observational study, BIOSTRAT (NCT03735719), enrolled 117 pts. Gal-3 and sST2 serum collection and echocardiography were performed twice (during index hospitalization and on a control visit at one-year follow-up). Assessedat baseline and at one-year echocardiographic indices included left ventricular ejection fraction (LVEF), atrial and ventricular size, LV posterior wall and septal thickness, LV hypertrophy based on LV mass index, mitral inflow velocities, and early diastolic tissue velocities at the lateral and medial mitral annulus. Results:Mean baseline concentrations of Gal-3 and sST2 (7.5 and 26.4 ng/mL, respectively) were increased at one-year follow-up (8.5 ng/mL, p &lt; 0.001 and 31.4 ng/mL, p = 0.001, respectively). Fifty of 105 pts (48%) developed HF and 30% of the study population had LVEF &lt;50% at one-year. There were no significant differences between pts with LVEF &lt;50% and ≥50% in terms of baseline, follow-up, nor changes in Gal-3 and sST2 concentrations from baseline to the one-year visit. Gal-3 and sST2 concentrations at baseline, after one-year, and their changes were correlated with echocardiographic parameters. Correlation analysis revealed that higher baseline Gal-3 concentrations correlated inversely only with LV end-diastolic volume at one-year. There were no other significant correlations of baseline, follow-up, nor changes in Gal-3 concentration with echocardiographic parameters. Baseline sST2 values correlated positively with LV end-diastolic diameter, LV end-systolic volume, LV mass index, and inversely with LVEF at one-year, but not with baseline echocardiographic parameters. Changes in sST2 concentration correlated positively only with LVEF at one-year. There were no significant correlations of sST2 concentrations at follow-up with echocardiographic parameters. Only pts with a higher sST2 baseline level had lower LVEF at baseline and after one-year, and pts with higher concentrations of both Gal-3 and sST2 at baseline were more likely to have LV hypertrophy initially and after one-year. There was no clear association of rising biomarkers’ quartiles with other echocardiographic parameters. Conclusions:There was no clear association between both biomarkers and echocardiographic parametersof diastolic dysfunction. Increasing levels of Gal-3 and sST2 do not reflect the HFpEF development in pts after STEMI.

Abstract Background Monitoring left-ventricular ejection fraction (LVEF) is a routinely-practiced strategy to survey patients with breast cancer (BC) towards cardiotoxic treatment effects. However, whether the LVEF as a single measurement or as a trajectory over time is truly sufficient to identify patients at high risk for cardiotoxicity is currently debated. Purpose To quantify the prognostic impact of LVEF and its change over time for predicting cardiotoxicity in women with HER2+ early BC. Methods We analyzed 1,136 echocardiography reports from 185 HER2+ early BC patients treated with trastuzumab ± chemoimmunoendocrine therapy in the neoadjuvant/adjuvant setting (Table 1). Cardiotoxicity was defined as a 10% decline in LVEF below 50%. Results Median baseline LVEF was 64% (25th-75th percentile: 60–69). Nineteen patients (10%) experienced cardiotoxicity (asymptomatic n=12, symptomatic n=7, during treatment n=19, treatment modification/termination n=14), Median time to cardiotoxicity was 6.7 months, and median LVEF decline in patients with cardiotoxicity was 18%. One-year cardiotoxicity risk was 7.6% in the 35 patients with a baseline LVEF≥60% and 24.5% in the 150 patients with a baseline LVEF<60% (Hazard Ratio (HR)=3.45, 95% CI: 1.35–8.75, Figure 1). During treatment, LVEF declined significantly faster in patients who developed cardiotoxicity than in patients without cardiotoxicity (1.3%/month vs. 0.1%/month, p<0.0001). A higher rate of LVEF decrease predicted for higher cardiotoxicity risk (HR per 0.1%/month higher LVEF decrease/month=2.50, 95% CI: 1.31–4.76, p=0.005), and cardiotoxicity risk increased by a factor of 1.7 per 5% absolute LVEF decline from baseline to first follow-up (HR=1.70, 95% CI: 1.30–2.38, p<0.0001). Thirty-six patients (19%) developed an LVEF decline of at least 5% from baseline to first follow-up (“early LVEF decline”). One-year cardiotoxicity risk was 6.8% in those without early LVEF decline and a baseline LVEF≥60% (n=117), 15.7% in those without an early LVEF decline and a baseline LVEF<60% (n=65), and 66.7% in those with an early LVEF decline and a baseline LVEF<60% (n=3), respectively (log-rank p<0.0001). Table 1. Baseline characteristics Age (years, median [IQR]) 55 [49–65] Estrogen receptor positive (n, %) 124 (67%) Neoadjuvant setting (n, %) 103 (56%) Figure 1. Risk of Cardiotoxicity. Conclusion Both a single LVEF measurement and the rate of LVEF decrease strongly predict cardiotoxicity in early BC patients undergoing HER2-targeted therapy. Routine LVEF monitoring identifies individuals at high risk of cardiotoxicity that may benefit from more sensitive screening techniques such as strain imaging.
