Results From 242 patients who completed 1-year follow-up, 9 % develop HF NYHA class 3 or 4, 27 % NYHA class 2 and remaining 64% were in NYHA class I. Significant univariate NYHA predictors were: from clinical parameters - female gender (ß =0.156, p = 0.015; 95% CI -0.431 to – 0.047), older age (ß =0.130, p = 0.044; 95% CI 0.000 to 0.017), Killip class on admission (ß=0.131, p = 0.043; 95% CI 0.007 to 0.435) and previous atrial fibrillation (ß=0.181, p = 0.005; 95% CI 0.175 to 0.960); from conventional echo parameters- LVEF (ß=-0.302, p < 0.001; 95% CI -0.029 to -0.012), LAVI (ß=0.134, p = 0.046; 95%CI 0.000 to 0.030), degree of diastolic dysfunction (ß=0.297, p < 0.001; 95% CI 0.192 to 0.465) and TAPSE (ß=-4.255, p < 0.001); from parameters of longitudinal LV deformation – peak systolic epicardial LS  (ß=0.293, p < 0.001; 95% CI 0.030 to 0.074), SRs (ß=0.274, p < 0.001; 95% CI 0.398 to 1.069) and epicardial PSS (ß=0.336, p < 0.001; 95%CI 0.925 to 2.019); from parameters of LV circumferential deformation – peak systolic endocardial CS (ß=0.254, p < 0.001; 95% CI 0.013 to 0.041), SR E (ß= -0.247, p < 0.001; 95%CI -0.556 to -0.173) and epicardial PSS CS (ß=0.206, p = 0.003; 95% CI 0.302 to 1.473); from left atrial mechanics - LA strain (ß=-0.231, p = 0.001; 95% CI -0.025 to -0.007). Predictive power of model based on clinical variables (Killip class on admission, female gender, and history of atrial fib) for HF development was significantly improved when conventional ehocardiographic variables were added (LVEF, TAPSE, degree of diastolic function) (R2 from 0.076 to 0.197, p < 0.001). However, addition of MDI parameters (longitudinal and cirumferential PSS on epicardial levels) increased it further (R2 from 0.200 to 0.229, p < 0.001). Conclusion above from clinical and conventional echocardiographic parameters, amount of left ventricular post-systolic deformation in longitudinal and circumferential directions, expressed as LV indexes of post-systolic shortening, significantly improved early prediction of HF after pPCI.

Abstract Heart failure (HF) development after myocardial infarction with ST segment elevation (STEMI) in the modern era varies greatly (between 4% and 28%), with the highest incidence in the first year. Since, HF still carries substantial morbidity and mortality, accurate and early identification of high-risk patients for HF development after pPCI allows for targeted use of intensive therapy. Aim The current study is a sub-study of PREDICT-VT study (NCT03263949). Its aim is to define multi-parametric model for early HF prediction in STEMI patients treated by pPCI, based on three data sets: clinical data, conventional echocardiographic data and data from myocardial deformation analysis obtained by early speckle tracking echocardiography. Methods In 264 consecutive pts enrolled in PREDICT-VT study early echocardiography (5±2 days after pPCI) was done and included LA and multilayer LV deformation analysis with longitudinal (L), radial (R) and circumferential (C) strain (S; %) and strain rate (SR, 1/sec). LV index of post systolic shortening for longitudinal strain (PSS LS) and for circumferential strain (PSS CS) were calculated for the purpose of this study as average of PSS over 18 LV segments. Results From 195 patients who completed 1-year follow-up, 17 (8.7%) develop HF NYHA class 3 or 4, 60 (30.8%) NYHA class 2 and remaining 118 patients (60.5%) were in NYHA class I. Significant univariate predictors of NYHA were: from clinical parameters – female gender (β=0.169, p=0018), Killip class on admission (β=0.253, p<0.001) and previous atrial fibrillation (β=0.205, p=0.004); from conventional echocardiographic parameters – LV WMSI (β=0.223, p=0.0072), LVEF (β=−0.256, p<0.001), LAVI (β=0.174, p=0.020) and TAPSE (β=−0.263, p=0.001); from parameters of longitudinal LV deformation – LS at the epicardial level (β=0.242, p=0.001) and PSS LS (β=0.360, p<0.001); from parameters of LV circumferential deformation – CS at epicardial level (β=0.225, p=0.001) and PSS CS at epicardial level (β=0.124, p=0.004); from left atrial mechanics – LA strain (β=−0.199, p=0.007). In multivariable stepwise regression model 5 variables were further identified as independent predictors that significantly increased model power to predict HF development (R square from 0.134 to 0.270, p<0.001). They are: PSS LS (β=0.255, p=0.002), previous atrial fibrilation (β=0.205, p=0.008), TAPSE (β=−0.176, p=0.031), female gender (β=0.165, p=0.032) and PSS CS (β=0.155, p=0.047). Conclusion Independently from and above classical clinical and echocardiographic parameters, amount of left ventricular post-systolic deformation in longitudinal and circumferential direction, expressed as LV indexes of post-systolic shortening, significantly improved early prediction of HF development after pPCI.

Abstract Data regarding heart failure (HF) development among patients with preserved EF (≥50%) after STEMI are spare. Accurate and early identification of patients at risk might allow timely application of modern therapy targeted for HFpEF. Aim the current study is a sub-study of PREDICT-VT (NCT03263949). Its aim was to determine the incidence and predictors of HFpEF development in STEMI patients treated by pPCI. Methods in 264 consecutive pts enrolled in PREDICT-VT study early echocardiography (5 ± 2 days after pPCI) was done and included multilayer LV deformation analysis with longitudinal (L), radial (R) and circumferential (C) strain (S; %) and strain rate (SR, 1/sec) and rotational LV mechanics. LV index of post systolic shortening for longitudinal strain (PSS LS) and for circumferential strain (PSS CS) were calculated as average of PSS over 18 LV segments. LV diastolic function was assessed according to the current ESC guidelines. Results From 264 patients enrolled in PREDICT-VT study, until now 195 patients completed one-year follow and among them 87 pts (46 %) had EF≥50%. From those patients during one-year follow-up 30 pts (30.3 %) develop HF: 3 pts NYHA class 3/ 4 and 27 pts NYHA class 2. Patients who developed HF (Group HF, n = 30) were older (62 ± 7 vs55 ± 11, p = 0.002), had lower E/A ratio (0.77 ± 0.25 vs 0.94 ± 0.32, p = 0.014), more commonly altered LV diastolic function (83 vs 60%, p = 0.028) compared with pts who remained in NYHA class I (Group none-HF, n = 57). There were no significant differences in LVEF, MI localisation, nor in WMSI between groups. Longitudinal and circumferential myocardial deformations did not differ significantly, except for more pronounced PSS LS on epicardial level in Group –HF (11.5 ±7.5 vs 8.3 ± 7.7%, p = 0.073). Rotation mechanic analysis revealed that Group –HF had increased (14.08 ± 5.5 vs 12.5 ± 5.4°, p = 0.202), but delayed twist (350 ± 69 vs 327 ± 68 ms, p = 0.139) with reduced magnitude of peak untwisting velocities (-88.58 ±34.16 vs -95.20 ± 39.75°/sec, p = 0.488). However, only statistically significant difference was increased magnitude of untwisting velocity during late diastole (-57.53 ± 30.61 vs -42.88 ± 27.78, p = 0.029). Significant univariate predictors of HF development were: older age (Exp (B)=1.08, CI 1.027-1.139, p = 0.03), E/A ratio (Exp (B) =0.130, p = 0.018, 95%CI 0.024-0.700), female gender (Exp (B)=2.933, 95% CI 1.163 -7.397, p = 0.023) and late-diastolic untwisting velocity (Exp (B)=0.983, 95%CI 0.967-0.999, p = 0.033). However, in multivariable analysis only older age (Exp B= 1.09, 95% CI 1.028-1.155, p = 0.004) and female gender (Exp B= 2.80, 95% CI 1.01-7.708, p = 0.046) remained significant predictors. Conclusion HF after STEMI in patients with preserved EF is not rare and probably substantially contributes to the total incidence HF after STEMI. However, its prediction remained challenging, with female gender and older age confirmed as its significant determinants.

Background: End-stage heart failure (HF) is refractory to current standard medical therapy, and the number of donor hearts is insufficient to meet the demand for transplantation. Recent studies suggest autologous stem cell therapy may regenerate cardiomyocytes, stimulate neovascularization, and improve cardiac function and clinical status. Although human fetal-derived stem cells (HFDSCs) have been studied for the treatment of a variety of conditions, no clinical studies have been reported to date on their use in treating HF. We sought to determine the efficacy and safety of HFDSC treatment in HF patients.Methods and Results: Direct myocardial transplantation of HFDSCs by open-chest surgical procedure was performed in 10 patients with HF due to nonischemic, nonchagasic dilated cardiomyopathy. Before and after the procedure, and with no changes in their preoperative doses of medications (digoxin, furosemide, spironolactone, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, betablockers), patients were assessed for New York Heart Association (NYHA) class, performance in the exercise tolerance test (ETT), ejection fraction (EF), left ventricular end-diastolic dimension (LVEDD) via transthoracic echocardiography, performance in the 6-minute walk test, and performance in the Minnesota congestive HF test. All 10 patients survived the operation. One patient had a stroke 3 days after the procedure, and although she later recovered, she was unable to perform the follow-up tests. Another male patient experienced pericardial effusion 3 weeks after the procedure. Although it resolved spontaneously, the patient abandoned his control tests and died 5 months after the procedure. An autopsy of the myocardium suggested that new young cells were present in the cardiomyocyte mix. At 40 months, the mean (SD) NYHA class decreased from 3.4 0.5 to 1.33 0.5 (P = .001); the mean EF increased 31%, from 26.6% 4% to 34.8% 7.2% (P = .005); and the mean ETT increased 291.3%, from 4.25 minutes to 16.63 minutes (128.9% increase in metabolic equivalents, from 2.46 to 5.63) (P < .0001); the mean LVEDD decreased 15%, from 6.85 0.6 cm to 5.80 0.58 cm (P < .001); mean performance in the 6-minute walk test increased by 43.2%, from 251 113.1 seconds to 360 0 seconds (P = .01); the mean distance increased 64.4%, from 284.4 144.9 m to 468.2 89.8 m (P = .004); and the mean result in the Minnesota test decreased from 71 27.3 to 6 5.9 (P < .001).Conclusion: Although these initial findings suggest direct myocardial implantation of HFDSCs is feasible and improves cardiac function in HF patients at 40 months, more clinical research is required to confirm these observations.

Abstract Funding Acknowledgements Type of funding sources: None. onbehalf PREDICT-VT More extensive coronary atherosclerosis in diabetes mellitu (DM) induces poorer clinical outcomes after STEMI, but there are data suggesting that impaired myocardial function in DM, even independently from epicardial coronary lesions severity, might have detrimental effect, predominately on heart failure development in DM. Aim the current study is a sub-study of PREDICT-VT study (NCT03263949), aimed to analyse LV and LA function using myocardial deformation imaging based on speckle tracking echocardiography after pPCI in STEMI patients with and without DM. Methods in 307 consecutive pts enrolled in PREDICT-VT study early echocardiography (5 ± 2 days after pPCI) was done including LA and multilayer LV deformation analysis with longitudinal (L), radial (R) and circumferential (C) strain (S; %) and strain rate (SR, 1/sec), LV index of post systolic shortening for longitudinal (PSS LS) and circumferential (PSS CS) strains and analysis of LV rotation mechanic. Results from 242 patients who completed 1 year follow up, 48 (20%) had DM. Pts with DM were older (60 ± 1,01 vs 57 ± 10; p = 0.067) and had insignificantly higher SYNTAX score (18.5 ± 9.2 vs 15.8 ± 9.8, p = 0.118) . However, diabetics had more severely impaired EF (44.2 ± 8.6 vs 49.2 ± 9.8, p = 0.001), E/A ratio (0.78 ± 0.33 vs 0.90 ± 0.34; p = 0.036) and MAPSE (1.18 ± 0.32 vs 1.32 ± 0.33; p = 0.001).  Global LV LS on all layers (endo: -13.6 ± 4.0 vs-16.2 ± 4.7; mid: -11.9 ± 3.5 vs -14.1 ± 4.1; epi: -10.4 ± 3.1 vs -12.3 ± 3.6; p &lt; 0.005 for all) was impaired in DM patients, as well as longitudinal systolic SR (-0.71 ± 0.23 vs -0.84 ± 0.24; p = 0.001) and SR during early diastole (0.65 ± 0.26 vs 0.83 ± 0.33, p &lt; 0.001). Patients with DM had more pronounced longitudinal posts-systolic shortening throughout LV wall (endo: 21.4 ± 16.1 vs 13.7 ± 13.3, p = 0.005; mid: 21.9 ± 16.1 vs 14.3 ± 13.1, p = 0.006; epi: 22.4 ± 16.5 vs 15.3 ± 13.7, p = 0.010) and higher LV mechanical dispersion (MDI: 71.3 ± 38.3 vs 59.0 ± 18.9, p = 0.037). LA strain was significantly impaired in DM patients (18.9 ± 7.7 vs 22.6 ± 10.0, p = 0.011) and even more profoundly LA strain rate during early diastole (-0.73 ± 0.48 vs -1.00 ±0.58, p = 0.002). Patients with DM also had more impaired LV global (15.7 ± 9.1 vs 19.8 ± 10.4, p = 0.013) radial strain, global LV circumferencial strain, especially at the mid-wall level (-13.9 ± 4.2 vs -16.0 ± 4.3, p = 0.005) and impaired circumferential SR E (1.25± 0.44 vs 1.49 ± 0.46, p = 0.003). End-systolic rotation of the LV apex was more impaired in DM (4.7 ± 5.1 vs 6.8 ± 5.5, p= 0.022). During 1 year follow-up heart failure and all-cause mortality tend to be higher among DM pts (46.7% vs 35.2%, p = 0.153). Conclusion STEMI patients with DM have more severely impaired LV systolic and diastolic function estimated both by traditional parameter and advanced echo techniques. These results might, at least partially, explain why outcomes after STEMI in DM might be poorer, even in the absence of more complex angiographic findings, pointing to the significance of impaired myocardial function DM itself.

Background: Left ventricular assist device (LVAD) therapy can improve survival and quality of life in advanced heart failure (HF), but some patients may still do poorly after LVAD. Understanding the likelihood of experiencing poorer outcomes after LVAD can better inform patients and calibrate their expectations. Methods: We analyzed patients receiving LVAD therapy from January 2012 to October 2013 at a single, high-volume, high-acuity center. We defined a poor global outcome at 1 year after LVAD as the occurrence of death, disabling stroke (precluding transplant), poor patient-reported health status (most recent KCCQ at 3, 6, or 12 months < 45, corresponding to NYHA class IV), or recurrent HF (≥2 HF readmissions post-implant). We compared characteristics of those with and without poor global outcome. Results: Among 164 LVAD recipients who had 1-year outcomes data, mean age was 56, 76.7% were white, 20.9% were female, and 85.9% were INTERMACS Profile 1 or 2 (cardiogenic shock or declining despite inotropes). Poor global outcome occurred in 58 (35.4%) patients at 1 year, of whom 37 (63.8%) died, 17 (29.3%) had a most recent KCCQ score < 45, 3 (5.2%) had ≥2 HF readmissions, and 1 (1.7%) had a disabling stroke (Figure). Eight of the patients who died also experienced one of the three other poor outcomes prior to death. Patients who experienced a poor global outcome were more likely to be designated for destination therapy (46.4% vs. 23.6%, p=0.01) than bridge to transplant, have longer index admissions (median [IQR]: 39 [24, 57] days vs. 25 [18, 35] days, p=0.003), and have major GI bleeding (44.2% vs. 27.7%, p=0.056), and were less likely to undergo LVAD exchange (0% vs. 12.3%, p=0.004). Conclusion: In this large, single-center study assessing global outcome after LVAD implantation, we found that about a third of all patients had experienced a poor global outcome at 1 year. While LVAD therapy remains life-saving and the standard of care for many patients with advanced heart failure, these findings could help guide discussions with eligible patients and families. Future work should compare patients’ pre-LVAD expectations with likely outcomes and create risk models to estimate the probability of poorer outcomes for individual patients using pre-procedural factors.

Background: One-third of HCM patients without left ventricular outflow tract obstruction under resting conditions have the propensity to develop an outflow gradient with physiologic exercise. However, the natural history and management implications of exercise-induced (i.e., provocable) obstruction is unresolved. Methods: We prospectively studied 533 consecutive HCM patients without outflow obstruction at rest (<30mmHg) who underwent a symptom limiting stress (exercise) echocardiogram to assess development of outflow obstruction following physiologic provocation and followed for 6.5 ± 2.0 years. Of the 533 patients, obstruction ≥ 30 mmHg was present following exercise in 262 patients (49%; provocable obstruction), and was absent both at rest and with exercise in 271 (51%; nonobstructive). Results: Over the follow-up period, 43 out of 220 (20%) HCM patients with provocable obstruction and baseline NYHA class I/II symptoms developed progressive limiting heart failure symptoms to class III/IV, compared to 24 of 249 (10%) nonobstructive patients. Rate of heart failure progression was significantly greater in patients with provocable obstruction vs. nonobstructive patients (3.1%/year vs. 1.5%/year; RR=2.0, 95% CI of 1.3-3.2; p=0.003). However, the vast majority of patients with provocable obstruction who developed advanced heart failure symptoms achieved substantial improvement in symptoms to class I / II following relief of obstruction with invasive septal reduction therapy (n=30/32; 94%). In comparison, the majority of nonobstructive patients who developed advanced heart failure remained in class III/IV (16/24;67%), including 10 (42%) currently listed for heart transplant. Conclusions: Stress (exercise) echocardiogram identifies physiological provocable outflow tract obstruction in HCM, and is a predictor of future risk for progressive heart failure (3.1%/year), in patients who become candidates for invasive septal reduction therapy. Therefore, exercise echocardiography should be considered in all HCM patients without obstruction under resting conditions.

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Norwegian South East Health Authorities Introduction Identification of disease modification prior to implantation of Cardiac Resynchronization Therapy may help select the right patients, increase responder-rates and promote the utilization of CRT. We tested the hypothesis that shortening of time-to-peak left ventricular pressure rise (Td) with CRT is useful to predict long-term volumetric response (End-systolic volume (ESV) decrease &gt;15%) to CRT. Methods Forty-five heart failure patients admitted for CRT implantation with a class I/IIa indication according to current ESC/AHA guidelines were included in the study. Td was measured from onset QRS at baseline and from onset of pacing with CRT. Results Baseline characteristics were mean age 63 ± 10 years , 71% males, NYHA class 2.5, 87% LBBB, QRS duration 173 ± 15ms, EF biplane 31 ± 1%, ESV 144 ± 12mL and end-diastolic volume 2044 ± 14mL. At 6-months follow-up six patients increased ESV by 5 ± 8%, while 37 responders (85%) had a mean ESV decrease of 40 ± 2%.  Responders presented with a higher Td at baseline compared to non-responders (163 ± 4ms vs 119 ± 9ms, p &lt; 0.01). Td decreased to 156 ± 4ms (p = 0.02) with CRT in responders, while in non-responders Td increased to 147 ± 10ms (p &lt; 0.01) with CRT. A decrease in Td of less than +3.5ms from baseline accurately identified responders to therapy (AUC 0.98, p &lt; 0.01, sensitivity 97%, specificity 100%). AUC was 0.92 for baseline Td and a cut-off at 120ms yielded a sensitivity of 100% and specificity of 80% to identify volumetric responders. A linear relationship between the change in Td from baseline and ESV decrease on long term was found (β=-61, R = 0.58, P &lt; 0.01). Conclusions Td at baseline and the shortening of Td with CRT accurately identifies responders to CRT, with incremental value on top of current guidelines, in a population with already high response rates. Td carries the potential to become the marker for prediction of long-term volumetric response in CRT candidates. Abstract Figure.

Abstract PurposeTrastuzumab improves survival in patients with HER2+ early breast cancer. However, cardiotoxicity remains a concern, particularly in the curative setting, and there are limited data on its incidence outside of clinical trials. We retrospectively evaluated the cardiotoxicity rates (left ventricular ejection fraction [LVEF] decline, congestive heart failure [CHF], cardiac death or trastuzumab discontinuation) and assessed the performance of a proposed model to predict cardiotoxicity in routine clinical practice.MethodsPatients receiving curative trastuzumab between 2011-2018 were identified. Demographics, treatments, assessments and toxicities were recorded. Fisher’s exact test, chi-squared and logistic regression were used.Results931 patients were included in the analysis. Median age was 54 years (range 24-83) and Charlson comorbidity index 0 (0-6), with 195 patients (20.9%) aged 65 or older. 228 (24.5%) were smokers. Anthracyclines were given in 608 (65.3%). Median number of trastuzumab doses was 18 (1-18). The HFA-ICOS cardiovascular risk was low in 401 patients (43.1%), medium in 454 (48.8%), high in 70 (7.5%) and very high in 6 (0.6%).Overall, 155 (16.6%) patients experienced cardiotoxicity: LVEF decline≥10% in 141 (15.1%), falling below 50% in 55 (5.9%), CHF NYHA class II in 42 (4.5%) and class III-IV in 5 (0.5%) and discontinuation due to cardiac reasons in 35 (3.8%). No deaths were observed.Cardiotoxicity rates increased with HFA-ICOS score (14.0% low, 16.7% medium, 30.3% high/very high; p=0.002). ConclusionsCardiotoxicity was relatively common (16.6%), but symptomatic heart failure on trastuzumab was rare in our cohort. The HFA-ICOS score identifies patients at high risk of cardiotoxicity

Introduction: Peak oxygen consumption (VO 2 ) has a strong and independent prognostic value in systolic heart failure; in contrast no data support its prognostic role in hypertrophic cardiomyopathy (HCM). Hypothesis: We assess if peak VO 2 is a long-term predictor of outcome in HCM. Methods: We studied 92 HCM patients (40±15 years). Peak VO 2 was expressed as percentage (%) of the predicted value. Follow up was 76±57 months. The primary composite endpoint (CE) was atrial fibrillation, progression to NYHA class III or IV, myotomy-myectomy (MM), heart transplantation (HT) and cardiac death. An ancillary endpoint (HFE) included markers of heart failure (progression to NYHA class III or IV, MM and HT). Results: At baseline, 62% of patients were asymptomatic, 35% NYHA class II and 3% NYHA class III; 26% had left ventricular outflow tract obstruction. During follow up, 30 patients met CE with 43 events. By multivariate Cox survival analysis, we analyzed 2 models, using the CE, and in turn HFE. For CE, maximal left atrial diameter (LAD) (HR: 1.12; 95% CI: 1.04 to 1.22), maximal wall thickness (MWT) (HR: 0.14; 95% CI: 1.04 to 1.23) and % predicted peak VO 2 (HR: -0.03; 95% CI: 0.95 to 0.99) independently predicted outcome (overall, p<0.0001). For HFE, maximal LAD (HR:0.31; 95% CI: 1.09 to 1.70), MWT (HR: 0.35; 95% CI: 1.08 to 1.84) and % predicted peak VO 2 (HR: -0.06; 95% CI: 0.89 to 0.98) independently predicted outcome (overall, p<0.0001). Only 19% of mildly symptomatic or asymptomatic patients with % predicted peak VO 2 >80% had events, as opposed to 53% of them with % predicted peak VO 2 < 55% (p= 0.04). Event-free survival for both endpoints was significantly lower in patients with % predicted peak VO 2 < 55% as compared to those with it between 55 and 80 and >80% , Figure. Conclusion: In mildly or asymptomatic patients severe exercise intolerance may precede clinical deterioration. In HCM, peak VO 2 provides excellent risk stratification with a high event rate in patients with % predicted value <55%.
