RationaleAdaptive servo ventilation (ASV) is contraindicated in patients with systolic heart failure (HF) who have a left ventricular ejection fraction (LVEF) below 45% and predominant central sleep apnoea (CSA). However, the effects of ASV in other HF subgroups have not been clearly defined.ObjectiveThe European, multicentre, prospective, observational cohort trial, FACE, evaluated the effects of ASV therapy on morbidity and mortality in patients with HF with sleep-disordered breathing (SDB); 3-month outcomes in patient subgroups defined using latent class analysis (LCA) are presented.MethodsConsecutive patients with HF with predominant CSA (±obstructive sleep apnoea) indicated for ASV were included from 2009 to 2018; the non-ASV group included patients who refused/were noncompliant with ASV. The primary endpoint was time to composite first event (all-cause death, lifesaving cardiovascular intervention or unplanned hospitalisation for worsening of chronic HF).Measurements and main resultsBaseline assessments were performed in 503 patients, and 482 underwent 3-month follow-up. LCA identified six discrete patient clusters characterised by variations in LVEF, SDB type, age, comorbidities and ASV acceptance. The 3- month rate of primary outcome events was significantly higher in cluster 1 patients (predominantly men, low LVEF, severe HF, CSA; 13.9% vs 1.5%–5% in other clusters, p<0.01).ConclusionFor the first time, our data identified homogeneous patient clusters representing clinically relevant subgroups relating to SDB management in patients with HF with different ASV usage, each with a different prognosis. This may improve patient phenotyping in clinical practice and allow individualisation of therapy.

Introduction: Chronicity of atrial fibrillation (AF) has been associated with poor cardiovascular outcomes. Left atrial function index (LAFI) is a rhythm-independent measure of LA reservoir function adjusted for LA size and stroke volume and is an established marker of risk for cardiac disease states. We sought to evaluate the role of LA function by LAFI in predicting persistent/permanent AF. Hypothesis: LAFI is a predictor of chronicity of AF. Methods: Patients attending our institution between Jan 2013 and Dec 2017 were assessed. Patients with history of non-valvular AF who received transthoracic echocardiogram (TTE) evaluation were included. In these patients, we evaluated demographic profiles, AF history, clinical comorbidities and echocardiographic data. We excluded patients with valvular AF, poor quality TTE images and incomplete clinical data. Results: Of the 665 patients (67.78±13.62years, 52% male) included, 27.8% had persistent/permanent AF. Persistent/permanent AF was associated with older age (p<0.01), heart failure (p<0.01), diabetes mellitus (p=0.02), ischaemic heart disease (p=0.02), obstructive sleep apnoea (p=0.04), renal impairment (p<0.01), lower left ventricular ejection fraction (p<0.01), higher E/e’ (p<0.01), larger LA volume index (p<0.01) and lower LAFI (p<0.01). Multi-variable analysis revealed both heart failure (OR 3.024, 95%CI 1.737 to 5.265, p<0.01) and LAFI (OR 4.881, 95%CI 2.503 to 9.519, p<0.01) as independent predictors of persistent/permanent AF. Receiver operating characteristic curve showed LAFI (see Figure; AUC 0.75, 95%CI 0.703 to 0.793, p<0.01) of less than 16.5 to have a 70% sensitivity and 70% specificity in detecting persistent/permanent AF. Conclusions: LAFI, an echocardiographic measure of atrial mechanical function, may be a useful tool in risk stratification for patients with non-valvular AF.

Resynchronisation Therapy

Cardiac resynchronisation therapy (CRT) is an efficacious and cost-effective therapy in patients with highly symptomatic systolic heart failure and delayed ventricular conduction. Current guidelines recommend CRT as a class I indication for patients with sinus rhythm, New York Heart Association (NYHA) functional class III or ambulatory class IV, a QRS duration ≥120ms, and left ventricular ejection fraction (LVEF) ≤35%, despite optimal pharmacological therapy. Recent trials resulted in an extension of current recommendations to patients with mild heart failure, patients with atrial fibrillation, and patients with an indication for permanent right ventricular pacing with the aim of morbidity reduction. The effectiveness of CRT in patients with narrow QRS, patients with end-stage heart failure and cardiogenic shock, and patients with an LVEF >35% still needs to be proved. This article reviews current evidence and clinical applications of CRT in heart failure and provides an outlook on future developments.

Background: The prognostic importance of right ventricular (RV) dysfunction has been suggested in patients with systolic heart failure (due to primary or secondary dilated cardiomyopathy - DCM). Tricuspid annular plane systolic excursion (TAPSE) is a simple, feasible, reality, non-invasive measurement by transthoracic echocardiography for evaluating RV systolic function. Objectives: To evaluate TAPSE in patients with primary or secondary DCM who have left ventricular ejection fraction ≤ 40% and to find the relation between TAPSE and LVEF, LVDd, RVDd, RVDd/LVDd, RA size, severity of TR and PAPs. Materials and Methods: 61 patients (36 males, 59%) mean age 58.6 ± 14.4 years old with clinical signs and symtomps of chronic heart failure which caused by primary or secondary DCM and LVEF ≤ 40% and 30 healthy subject (15 males, 50%) mean age 57.1 ± 16.8 were included in this study. All patients and controls were underwent echocardiographic examination by M-mode, two dimentional, convensional Dopler and TAPSE. Results: TAPSE is significant low in patients compare with the controls (13.93±2.78 mm vs 23.57± 1.60mm, p<0.001). TAPSE is linearly positive correlate with echocardiographic left ventricular ejection fraction (r= 0,43; p<0,001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation was found with LVDd and PAPs. Conclusions: 1. Decreased RV systolic function as estimated by TAPSE in patients with systolic heart failure primary and secondary DCM) compare with controls. 2. TAPSE is linearly positive correlate with LVEF (r= 0.43; p<0.001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation is found with LVDd and PAPs. 3. TAPSE should be used routinely as a simple, feasible, reality method of estimating RV function in the patients systolic heart failure DCM (primary and secondary).

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.

Uremic Syndrome

Complement-mediated hemolytic uremic syndrome (otherwise known as atypical HUS) is a rare disorder of uncontrolled complement activation that may be associated with heart failure. We report the case of a 49-year-old female with no history of heart disease who presented with microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Given her normal ADAMSTS13 activity, evidence of increased complement activation, and renal biopsy showing evidence of thrombotic microangiopathy, she was diagnosed with complement-mediated HUS. She subsequently developed acute hypoxemic respiratory failure secondary to pulmonary edema requiring intubation and mechanical ventilation. A transthoracic echocardiogram showed evidence of a Takotsubo cardiomyopathy with an estimated left ventricular ejection fraction of 20%, though ischemic cardiomyopathy could not be ruled out. Treatment was initiated with eculizumab. After several failed attempts at extubation, she eventually underwent tracheotomy. She also required hemodialysis to improve her uremia and hypervolemia. After seven weeks of hospitalization and five doses of eculizumab, her renal function and respiratory status improved, and she was discharged in stable condition on room air and independent of hemodialysis. Our case illustrates a rare association between acute systolic heart failure and complement-mediated HUS and highlights the potential of eculizumab in stabilizing even the most critically-ill patients with complement-mediated disease.

Introduction: Stable organized atrial tachyarrhythmias (ATs) /"rotors" that maintain AF have been identified in patients (pts) with paroxysmal atrial fibrillation (PAF) & persistent AF (PRAF) with no or minimal heart disease. Hypothesis: Biatrial ATs occur in AF pts with systolic heart failure (HF). Methods: We performed simultaneous contact catheter mapping of the RA & LA using 3 D non-contact mapping ) in 83 refractory AF pts during spontaneous AF episodes.Spontaneous atrial premature beats (APBs) & triggered ATs were analyzed. We also compared regional distribution of ATs & activation patterns in pts with & without HF. Results: 24 HF pts, mean age of 62±9 years, 75% male with mean left ventricular ejection fraction (LVEF) 45.5±9% and mean left atrial (LA) size 4.35±0.8 cm were mapped. They had 42 APBs that triggered 26 distinct organized stable ATs/"rotors". Each pt had 1 to 4 RA or LA regions showing triggering APBs (mean 1.75/pt) initiating AT. APBs arose predominantly from the RA or LA septum (45%) & superior LA/PV (24%) regions (Fig 1a). A biatrial distribution of the stable ATs/"rotors" occcurred in HF pts (Fig 1b) with few focal ATs. Compared to pts without HF (n=59), HF pts (n=24) trended to have more PRAF (83% vs 66%, p=0.18). 78 organized stable ATs/"rotors" were compared for regional distribution in PRAF pts with HF (n=16) & without HF (n=32). Stable ATs with focal LA/PV origin were uncommon in both groups (7% vs. 15%). LA ATs/"rotors" were similar (26% vs. 17%; p=0.58) as were typical RA flutter and atypical RA ATs/"rotors" in both groups (Fig 1c). Conclusions: 1. A majority of APBs initiating AF in HF pts originated from the septal and superior LA/PV regions. 2. While triggers are still frequently present with the LA/PV origin in HF pts, stable ATs/"rotors" had biatrial distribution & a lesser frequency of focal LA/PV ATs. 3. This spectrum of ATs/"rotors" was similar to PRAF pts without HF, potentially supporting similar ablative interventions in both pt groups.

Abstract Background Sleep-disordered breathing (SDB) is highly frequent in patients with severe heart failure (HF). SDB, and predominantly central sleep apnea (CSA), may improve after recovery of cardiac function, but available data are limited and inconclusive, especially in patients who have undergone heart transplantation. The assessment of the severity of sleep apnea is mainly based on the apnea-hypopnea index (AHI), but this event-based parameter alone may not sufficiently reflect the complex pathophysiological mechanisms underlying SDB potentially contributing to adverse outcomes in patients with heart failure. Purpose To assess SDB in patients with severe HF before and after heart transplantation, their relationship with biomarkers and clinical parameters. Methods We included 117 patients (mean age 52.4±4.7 years) with HF NYHA class II-IV in the prospective cohort study, follow-up period was 5 years. The left ventricular ejection fraction (LVEF) was 28.05±9.57%. All patients underwent a comprehensive clinical examination, echocardiography, polysomnography (PSG, Embla N7000, Natus, USA). The plasma level of NT-proBNP, was analyzed by immunoassay (ELISA). The SPSS statistical software (version 23.0) was used. Results PSG showed the following types of SDB in the studied cohort: obstructive sleep apnoea (OSA) was diagnosed in 48 patients (41%), central - in 20 (17%), mixed - in 26 (22%). Among them mild SDB was diagnosed in 29 cases, moderate in 32 and severe in 33 patients. SDB was not found in 23 patients. The following correlations were identified: NT-proBNP and obstructive apnea index (OAI) (r=−0.44, p=0.007), NT-proBNP and sleep efficiency (r=−0.71, p=0.006), AHI and body mass index (BMI) (r=0.32, p=0.01), OAI and BMI index (r=0.34, p<0.001), desaturation index and BMI (r=0.43, p<0.001), average saturation oxygen and BMI (r=−0,6, p<0,001). Twenty-three patients underwent heart transplantation. According PSG-data 1 year after transplantation we observed decrease of central apnea index (CAI) (p=0,04). On the other hand, OAI increased (p=0,01) independently of the significant change in BMI (p=0,08). Conclusion We found very high rate of SDB (80%) in patients with severe HF, the predominant type was OSA. AHI, OAI and indicators of oxygen saturation correlate with BMI and biomarkers before heart transplantation. After 1 year after transplantation CAI decreased, assessment of the dynamics of obstructive sleep apnea requires further study.
