Abstract Background Arterial stiffness has been implicated in pathophysiology of heart failure (HF) since it is involved in the ventricular-vascular coupling. Recently, new indices obtained by a cuff oscillometric technique, the arterial velocity-pulse index (AVI) for the stiffness of central arteries and the arterial pressure-volume index (API) for the stiffness of peripheral arteries have been developed and validated. However, the AVI and API measurement has not been attempted in HF population. Purpose This study aimed to investigate the relationship between the AVI, API and clinical outcomes in HF patients. Methods A prospective cohort of patients with acute decompensated HF were enrolled within 6 months, who were admitted to a tertiary referral hospital in China. Measurement of the AVI and API (AVE-1500, Shisei Datum, Tokyo, Japan) was performed on the day of admission and discharge. Patients were followed up to 6 months for the composite endpoint of all-cause death and HF rehospitalization. Results A Total of 127 patients were recruited for analysis (60±15 years, 70% male). 80% of the patients were in New York Heart Association (NYHA) Class III or above at admission, who presented a mean left ventricular ejection fraction (LVEF) of 34±9%. During hospitalization, all patients received guideline directed medical therapy if not contraindicated. The AVI (27.3±5.2 vs. 28.6±6.7, p=0.002) and API (24.9±4.9 vs. 26.0±6.5, p=0.05) were lower at discharge than at admission. By dividing the patients into tertiles according to the amino-terminal pro-brain natriuretic peptide (NT-proBNP), LVEF, transmitral E velocity over mitral annular e' velocity (E/e' ratio) and systolic blood pressure (SBP) at admission, it was observed that the AVI increased with a higher level of NT-proBNP (p for trend <0.001), a larger E/e' (p<0.001) and a lower LVEF (p=0.001), while the API increased as the SBP became higher (p=0.005).The improvement in AVI at discharge was correlated with that in LVEF (R=-0.3024, p<0.05) and NT-proBNP (R=0.3118, p<0.05), while the change in API was positively correlated with that in SBP (R=0.3897, p<0.001). In 6 months after discharge, there were 52 predefined events including 15 deaths and 44 HF rehospitalization. Apart from the level of NT-proBNP, the AVI at discharge of ≥26 showed a trend of being associated with the composite outcome (2.747, 1.411–5.349, p<0.001 for univariate analysis; 1.8648, 0.8928–3.8949, p=0.0973 for multivariate analysis). Conclusions New noninvasive arterial stiffness indices as the AVI and API reflected severity of illness and mid-term prognosis in admitted HF patients. Further studies are warranted for understanding its mechanisms and developing clinical applications.

Abstract Background Arterial stiffness is strongly linked to the pathogenesis of heart failure and the development of acute decompensation in patients with stable chronic heart failure. This study aimed to compare arterial stiffness indices in patients with heart failure with reduced ejection fraction (HFrEF) during the acute decompensated state, and three months later after hospital discharge during the compensated state. Results One hundred patients with acute decompensated HFrEF (NYHA class III and IV) and left ventricular ejection fraction ≤ 35% were included in the study. During the initial and follow-up visits, all patients underwent full medical history taking, clinical examination, transthoracic echocardiography, and non-invasive pulse wave analysis by the Mobil-O-Graph 24-h device for measurement of arterial stiffness. The mean age was 51.6 ± 6.1 years and 80% of the participants were males. There was a significant reduction of the central arterial stiffness indices in patients with HFrEF during the compensated state compared to the decompensated state. During the decompensated state, patients presented with NYHA FC IV (n = 64) showed higher AI (24.5 ± 10.0 vs. 16.8 ± 8.6, p < 0.001) and pulse wave velocity (9.2 ± 1.3 vs. 8.5 ± 1.2, p = 0.021) than patients with NYHA FC III, and despite the relatively smaller number of females, they showed higher stiffness indices than males. Conclusions Central arterial stiffness indices in patients with HFrEF were significantly lower in the compensated state than in the decompensated state. Patients with NYHA FC IV and female patients showed higher stiffness indices in their decompensated state of heart failure.

The Relationship

Background: To investigate the relationship between arterial stiffness, reflected by cardio-ankle vascular index (CAVI) value, and left atrial (LA) phasic function in hypertensive patients with preserved left ventricular ejection fraction (LVEF).Methods: We retrospectively studied 165 consecutive patients (mean age, 66.5 ± 11.7 years) diagnosed with hypertension with preserved LVEF who had undergone CAVI measurement and echocardiography on the same day. The latter included speckle-tracking echocardiography to assess LA phasic function (reservoir, conduit, and pump strain) and left ventricular global longitudinal strain (LVGLS).Results: The results of univariate analysis showed CAVI value to be correlated with LA reservoir strain and LA conduit strain (r = −0.387 and −0.448, respectively; both P &lt; 0.0001). The results of multiple linear regression analysis showed CAVI value to be independently related to age (β = 0.241, P = 0.002) and LA conduit strain (β = −0.386, P = 0.021) but not LV mass index, LA volume index, or LV systolic function (including LVGLS).Conclusion: In hypertensive patients with preserved LVEF, increased CAVI value appears to be independently associated with impaired LA phasic function (particularly LA conduit function) before LA and LV remodeling. CAVI determination to assess arterial stiffness may be useful in the early detection of interactions between cardiovascular abnormalities in hypertensive patients.

Cardiac microRNA-132-3p (miR-132) levels are elevated in people suffering with heart failure (HF) and mechanistically drive remodelling processes in the heart. Here we present CDR132L, a specific antisense oligonucleotide. It is a first-in-class miR-132 inhibitor that attenuates and even reverses HF in preclinical models. The aim of this clinical Phase 1b study was to assess safety, pharmacokinetics, target engagement, and pharmacodynamics of CDR132L in patients on therapy for chronic ischaemic HF in a randomized, placebo-controlled, double-blind, dose-escalation study. Inclusion criteria for participant patients was left ventricular ejection fraction between 30 and 50% or levels of amino terminal fragment of pro-brain natriuretic peptide (NT-proBNP) higher than 125 ng/L at screening. Twenty-eight patients were randomized to receive CDR132L (0.32, 1, 3, and 10 mg/kg body weight) or placebo (0.9% saline) in two intravenous infusions, 4 weeks apart. Randomization separated participants into four cohorts of seven (five verum and two placebo). Results revealed that CDR132L was safe and well tolerated, and there was no detectable dose-limiting toxicity. A pharmacokinetic/pharmacodynamic dose modelling approach suggested an effective dose level of ≥1 mg/kg CDR132L. CDR132L treatment resulted in a dose-dependent, sustained miR-132 reduction in plasma. Patients who were administered ≥1 mg/kg of CDR132L displayed 23.3% NT-proBNP reduction, whereas patients receiving placebo experienced a 0.9% increase. In addition, CDR132L treatment was observed to significantly reduce duration of the QRS interval. This is the first clinical trial in which an antisense oligonucleotide was administered as a therapeutic agent to HF patients. Linear plasma pharmacokinetics were confirmed, and there were no signs of accumulation. The application of this drug suggests cardiac functional improvements and cardiac remodelling. The efficacy of this drug is encouraging, and further clinical work with larger patient populations should follow. Although the study used small patient numbers, results suggest some clinical benefit in chronic HF patients on the top of standard of care. This included an improvement in HF severity and narrowing of the QRS complex. The pharmacodynamic findings presented here are encouraging as they confirm efficacy results seen in animal studies.

Abstract Objective: Micro- and macrovascular changes can occur in heart failure, and could influence its prognosis and management. In a prospective study, we proposed the evaluation of arterial stiffness (macrovascular function) and its correlations in patients with systolic heart failure. Methods: 40 patients (32 men, 8 women, mean age 63±2.9 years), with hemodynamically stable systolic heart failure (left ventricular ejection fraction, EF<40%) were enrolled in the study. In every patient, beyond routine explorations (ECG, cardiac and carotid ultrasound, laboratory measurements), arterial stiffness was assessed by measuring pulse wave velocity (PWV). The correlations of PWV with clinical and echo-cardiographic characteristics were studied using t-test and chi-square test (p<0.05 being considered for statistical significance). Results: The average PWV was 8.55±2.2 m/s, and 16 patients had increased PWV (>10 m/s). We found significantly higher PWV values in patients older than 65 years (p<0.001), in patients with eGFR <60 ml/min/1.73 m2 (p<0.001), hypertension (p=0.006), and increased (>1 mm) carotid intima-media thickness (p=0.016). PWV was found to be significantly lower when EF was <30% (p=0.049). Furthermore, the presence of an increased PWV was correlated significantly with age (p<0.001), and (with borderline significance) with eGFR <60 ml/min/1.73 m2 and, inversely, with EF<30%. Conclusions: Increased arterial stiffness reflected by high PWV is frequently present in patients with systolic heart failure, and is mainly correlated with general risk factors of arterial involvement. Low EF, due to low stroke volume and decreased systolic arterial wall tension can influence the values and the interpretation of PWV.

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

Main funding source(s): European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie. Grant support from the Dutch Heart Foundation [NHS2010B233] Background. Atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) are two cardiovascular conditions that often coexist. Overlapping symptoms, biomarker profile, and echocardiographic changes hinder the diagnosis of underlying HFpEF in patients with AF and suggest that both conditions might reflect similar remodelling processes in the heart. Purpose. To assess cardiac remodelling in AF patients with versus without concomitant HFpEF by transthoracic echocardiography, focusing on atrial dimension and strain. Methods. We selected 120 patients included in AF-RISK, a prospective, observational, multicentre study aiming to identify a risk profile to guide atrial fibrillation therapy study. Patients had paroxysmal AF diagnosed within three years before inclusion, had a left ventricular ejection fraction (LVEF) ≥50% and were in sinus rhythm at the moment of performing echocardiography and blood sampling. Patients were matched by nearest neighbour by age and sex with a 1:1 ratio and were classified into two groups: 1) AF with HFpEF (n = 60) and 2) AF without HFpEF (n = 60). The diagnosis of HFpEF was based on the 2016 ESC heart failure guidelines, including symptoms and signs of heart failure, N-terminal pro-B-type natriuretic peptide (NT-proBNP) ≥125pg/ml, and one of the following echocardiographic measures: left atrium volume index (LAVI) &gt;34ml/m2, left ventricular mass index ≥115g/m2 for men and ≥95g/m2 for women, average E/e’ ≥13cm/s and average e’ &lt;9cm/s. Measurements of reservoir, conduit and contraction strain of both atria were performed in apical four-chamber by echocardiography (GE, EchoPac BT12). Associations of clinical and echocardiographic characteristics were tested for collinearity by multivariable logistic regression analyses. LAVI, LV mass index and NT-proBNP were excluded from multivariable analysis since these markers were part of the HFpEF diagnostic criteria. Results. Patients with paroxysmal AF and concomitant HFpEF had more often hypertension (72% vs. 45%, P = 0.005), had more impaired strain phases of both the left and right atria (figure 1), had comparable LVEF and global longitudinal strain (GLS) (P = 0.168 and P = 0.212, respectively). In a model adjusted for the number of comorbidities and sex, LA contraction decrease was associated with presence of HFpEF (odds ratio per 1% LA contraction-percent was 0.94, 95% confidence interval 0.87–0.99, P = 0.042). LA contraction was not explained by LAVI in patients with concomitant HFpEF (Spearman’s rho= -0.07, P = 0.08). Conclusion. Our results show that atrial function may differentiate paroxysmal AF patients with HFpEF from those without HFpEF. In patients with paroxysmal AF, more impaired strain phases of the left and right atria were associated with concomitant HFpEF, whereas ventricular function, reflected by LVEF and GLS, did not differ.

Multicenter Observational Study

Background: Sarcopenia is associated with poor prognosis in chronic heart failure. Fat-free mass index (FFMI) is an indicator of resting energy expenditure and has been used for the clinical diagnosis of sarcopenia. However, the prognostic impact of sarcopenia diagnosed by FFMI remains to be elucidated in patients admitted with acute decompensated heart failure (ADHF) and preserved LVEF (HFpEF), relating to gender. Methods: Patients' data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT-HFpEF) study, which is a prospective multicenter observational registry for ADHF patients with LVEF ≥50% in Osaka. We studied 621 patients who survived to discharge (men, n=281 and women, n=340). Fat-free mass (FFM) was estimated by the formula [FFM (kg) = 7.38 + 0.02908 х urinary creatinine (mg/day)] and normalized by the square of the patient’s height in meters to calculate FFMI at discharge. Sarcopenia was defined as FFMI <17 kg/m2 in men and <15 kg/m2 in women. The endpoint was all-cause death. Results: During a follow-up period of 1.5±0.8 yrs, 102 patients died (men, n=46 and women, n=56). At multivariate Cox analysis, FFMI was significantly associated with the mortality independently of age, estimated glomerular filtration rate, NT-proBNP and LVEF in both men (p=0.0155) and women (p=0.0223). Patients with sarcopenia had a significantly higher risk of all-cause death than those without sarcopenia in both genders (Figure). Conclusions: In this multicenter study, sarcopenia diagnosed by FFMI was shown to be associated with poor clinical outcome in HFpEF patients admitted with ADHF in both genders.

152 consecutive patients with myocarditis according to the quantitative World Heart Federation Criteria (> 14 infiltrating cells/mm 2 by endomyocardial biopsy(EMB)) were analysed for cardiotropic agents. In 90 pts parvoviruses B19 (59,5%) and in 36 pts adenoviruses (23,8%) were assessd by PCR as causative viral pathogens. All virus positive patients were treated with 10 g/day Pentaglobin® i. v.(enriched IgG, IgA and IgM preparation, Biotest) at day 1 and 3. After six months all patients were reevalutated clinically, 73 patients (48%) in addition by EMB. Methods: We compared the following parameters before and after therapy: left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), shortening fraction (SF) by transthoracic echocardiography and LVEF or the left ventricular end-diastolic volume index (LVEDVI) using angiography. For exercise capacity we evaluated exercise ECG by treadmill test and clinical parameters according to the NYHA classification, before and after therapy. Results: After Pentaglobin therapy, all patients demonstrated a significant clinical improvement of the NYHA class, of exercise capacity and of LVEF (from 54,4 to 60,0%, p<0,005) independent from the respective virus. In 52 of 73 (71%) rebiopsied pts inflammation had resolved. In 17 of the 19 rebiopsied patients (90%) with a positive PCR for ADV before therapy no more virus DNA was recovered after treatment, inflammation had resolved completely. In Parvo B 19 myocarditis inflammation had resolved in 31 of the 44 pts (70%), whereas Parvo B19 DNA was eradicated in only in 18 out of 44 pts(40%). In patients in whom both virus and inflammation were eliminated enddiastolic LV dimension decreased and EF increased significantly (p<0,001). Conclusion: Treatment with an intermediate dose of Pentaglobin is highly effective in resolving myocardial inflammation independent of the underlying viral etiology, but it eradicates adenoviral much better than Parvo B19 infection.

Diuretic Resistance

Background: Diuretic resistance is associated with poor clinical outcome in patients with acute decompensated heart failure (ADHF). However, little information is available on the prognostic significance of diuretic resistance in ADHF patients, relating to reduced, mid-range, or preserved left ventricular ejection fraction (LVEF). Methods: We studied 400 consecutive patients who were admitted for ADHF and survived to discharge. Diuretic resistance (DR) was defined by furosemide dose per body weight (BW) at discharge. Patients were classified by DR, and high dose group (higher DR) was defined by furosemide dose of > median value of DR (0.580). The endpoint was a composite of all-cause mortality and unplanned hospitalization for worsening heart failure. Results: There were 139 patients with heart failure with reduced LVEF (HFrEF, LVEF<40%), 86 with mid-range LVEF (HFmrEF, 40%≤LVEF<50%) and 175 with preserved LVEF (HFpEF, LVEF≥50%). There was no significant difference in DR among the three groups (HFrEF; median 0.541 [IQR 0.360-0.786] mg/kg vs HFmrEF; 0.606 [0.398-0.820] mg/kg vs HFpEF; 0.624 [0.380-0.935] mg/kg, p=NS). During follow-up of 2.4±1.6 years, 195 patients reached the endpoint (HFrEF, n=67, HFmrEF, n=44, and HFpEF, n=84). In multivariate Cox analysis, DR was significantly associated with the endpoint independently of age, estimated glomerular filtration rate, plasma brain natriuretic peptide level and LVEF only in HFpEF patients (p<0.0001). Kaplan-Meier analysis showed that the risk of the endpoint was significantly higher in the patients with higher DR in HFpEF patients, but not in HFrEF or HFmrEF patients (Figure). Conclusions: In this study, higher DR was shown to be associated with poor clinical outcome in HFpEF patients admitted with ADHF.

Diuretic Response

Background. The diuretic response has been shown to be a robust independent marker of cardiovascular outcomes in acute heart failure patients. The objectives of this clinical research are to analyze two different formulas (diuretic response (DR) or response to diuretic (R-to-D)) in predicting 6-month clinical outcomes. Methods: Consecutive patients discharged alive after an acute decompensated heart failure (ADHF) were enrolled. All patients underwent N-terminal-pro hormone BNP (NT-proBNP) and an echocardiogram together with DR and R-to-D calculation during diuretic administration. Death by any cause, cardiac transplantation and worsening heart failure (HF) requiring readmission to hospital were considered cardiovascular events. Results: 263 patients (62% male, age 78 years) were analyzed at 6-month follow-up. During the follow-up 58 (22.05%) events were scheduled. Patients who experienced CV-event had a worse renal function (p = 0.001), a higher NT-proBNP (p = 0.001), a lower left ventricular ejection fraction (p = 0.01), DR (p = 0.02) and R-to-D (p = 0.03). Spearman rho’s correlation coefficient showed a strong direct correlation between DR and R to D in all patients (r = 0.93; p < 0.001) and both in heart failure with reduced ejection fraction (HFrEF) (r = 0.94; p < 0.001) and HF preserved ejection fraction (HFpEF) (r = 0.91; p < 0.001). At multivariate analysis, a value of R-to-D <1.69 kg/40 mg, but only <0.67 kg/40 mg for DR were significantly related to poor 6-month outcome (p = 0.04 and p = 0.05, respectively). Receiver operating characteristic (ROC) curve analyses demonstrated that DR and R-to-D are equivalent in predicting prognosis (area under curve (AUC): 0.39 and 0.40, respectively). Only R-to-D was inversely related to in-hospital stay (r = −0.23; p = 0.01). Conclusion: Adding diuresis to DR seemed to provide a better risk assessment in alive HF patients discharged after an acute decompensation.
