Aims. Right ventricular (RV) dysfunction is a predictor of adverse outcomes among patients with HF with reduced ejection fraction (HFrEF) however, differences in RV parameters in HFrEF patients with ischemic (ICM) and non-ischemic cardiomyopathies (NICM) are not well understood. We investigated echocardiographic characteristics, including RV strain, in patients with acute decompensated heart failure (ADHF) and compared patients with ICM and NICM etiology. Methods. Consecutive patients who presented with ADHF and NYHA class III-IV were prospectively enrolled if they had LVEF <40% and history of ICM or NICM. All patients underwent clinical exam, laboratory evaluation and 2-D echocardiographic assessment of the left ventricular (LV) and RV function, LV and RV global longitudinal strain (LVGLS, RVGLS), and RV free wall strain (RVfwLS). Results. Of 84 patients, 44 had ICM and 40 NICM. The groups had similar blood pressure, NT-proBNP, and echocardiographic parameters of LV function including LVGLS. Absolute RVGLS values were lower than RVfwLS values in both groups. Patients with NICM had significantly lower RVfwLS, but not RVGLS, compared to patients with ICM (-13% to -17%, P=0.006). Similar differences in RVfwLS were seen in patients in NYHA class III (NICM vs ICM: -13% and -17%, respectively, 95% CI: -8.5 to -0.5) and NYHA class IV (NICM vs ICM: -13.8% and -17%, respectively, 95% CI: -6.4 to -0.59). Conclusion. Among patients hospitalized with ADHF, patients with nonischemic etiology compared with the patients with ICM, have worse RV dysfunction measured by RVfwLS, despite similar extent of LV impairment and the same functional limitation class.

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 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.

: Pacemaker induced cardiomyopathy (PICM) is commonly defined as a reduction in left ventricular (LV) function in the setting of right ventricular (RV) pacing. This condition may be associated with the onset of clinical heart failure in those affected. Recent studies have focused on potential methods of identifying patients at risk of this condition, in addition to hypothesizing the most efficacious ways to manage these patients. Newer pacing options, such as His bundle pacing, may avoid the onset of PICM entirely.

Introduction : Elevated filling pressures are a hallmark of chronic heart failure. They can be reduced acutely during HF hospitalization but the hemodynamic impact of ongoing therapy to maintain optivolemia has not been established. Methods and Results : After recent HF hospitalization, 274 NYHA Class III or IV HF patients were enrolled in the COMPASS-HF study at 28 experienced HF centers and received intense HF management (average 24.7 staff contacts/ 6 months) ± access to filling pressure information to adjust diuretics to maintain optivolemia, usually defined as estimated pulmonary artery diastolic (PAD) pressure of 12±4 mmHg. Filling pressure information was available for half the patients during the first 6 months (the Chronicle group, <Access), and for all patients during the next 6 months. Diuretics were adjusted 12.7 times per patient in the Chronicle group and 8.2 times per patient in the Control (-Access) group during the first 6 months (p = 0.0001). Compared to baseline, decreases in RV systolic pressure (RVSP) and ePAD were significant for the +Access patients by one year (p=0.0012 and p =.04, respectively). The Control patients exhibited a similar trend 6 months after crossing to +Access (figure ). Conclusions: Targeted therapeutic adjustments, based on continuous filling pressures along with intensification of HF management contacts, are associated with a reduction in chronic left-sided filling pressures and right ventricular load.

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 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

Abstract Funding Acknowledgements Type of funding sources: None. BACKGROUND The recent Heart Failure Association (HFA) of the European Society of Cardiology (ESC) consensus guidelines on diagnosis of heart failure with preserved ejection fraction (HFpEF) have developed a simple diagnostic algorithm for clinical use. PURPOSE To assess whether echocardiogram (echo) parameters needed to assess diastolic function are routinely collected in patients referred for assessment of heart failure symptoms. METHODS Retrospective analysis of echo referrals in January 2020 were assessed for parameters of diastolic function as per step 2 of the HF-PEFF diagnostic algorithm.  Echo images and clinical reports were reviewed. Electronic records were utilised to obtain clinical history, blood results (NT-proBNP) and demographic data. RESULTS 1330 patients underwent an echo in our department during January 2020. 83 patients were referred with symptoms of heart failure without prior history of cardiac disease; 20 patients found to have impaired left ventricular (LV) function were excluded from analysis. Of the 63 patients with possible HFpEF, HF-PEFF score was low in 18, intermediate in 33 and high in 12. Median age was 68 years (range 32 to 97 years); 25% had a BMI &gt;30. There was a high prevalence of hypertension (52%), diabetes (19%) and atrial fibrillation (40%) (cf. Table 1). Body surface area (BSA) was documented in 65% of echo reports. Most echo parameters were recorded with the exception of global longitudinal strain (GLS) and indexed LV mass (cf. image 1). NT-proBNP was recorded in only 20 patients (31.7%). 12 patients with an intermediate HF-PEFF score could have been re-categorised to a high score depending on GLS and NT-proBNP (which were not recorded). CONCLUSION More than three quarters of echoes acquired in our department obtained the relevant parameters to assess diastolic function. The addition of BSA, and inclusion of NT-proBNP, and GLS would have been additive to a third of ‘intermediate’ patients to determine definite HFpEF. Our study demonstrates that the current HFA-ESC diagnostic algorithm and HF-PEFF scoring system are easy to use, highly relevant and applicable to current clinical practice.

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%.
