Background: Kynurenine, a metabolite of the L-tryptophan pathway, plays a pivotal role in neuro-inflammation, cancer immunology, and cardiovascular inflammation, and has been shown to predict cardiovascular events. Objectives: It was our objective to increase the body of data regarding the value of kynurenine as a biomarker in chronic heart failure (CHF). Methods: We investigated the predictive value of plasma kynurenine in a CHF cohort (CHF, n = 114); in a second cohort of defibrillator carriers with CHF (AICD, n = 156), we determined clinical and biochemical determinants of the marker which was measured by enzyme immunoassay. Results: In the CHF cohort, both kynurenine and NT-proBNP increased with NYHA class. Univariate binary logistic regression showed kynurenine to predict death within a 6-month follow-up (OR 1.43, 95% CI 1.03–2.00, p = 0.033) whereas NT-proBNP did not contribute significantly. Kynurenine, like NT-proBNP, was able to discriminate at a 30% threshold of left ventricular ejection fraction (LVEF; AUC-ROC, both 0.74). Kynurenine correlated inversely with LVEF (ϱ = –0.394), glomerular filtration fraction (GFR; ϱ = –0.615), and peak VO2 (ϱ = –0.626). Moreover, there was a strong correlation of kynurenine with NT-proBNP (ϱ = 0.615). In the AICD cohort, multiple linear regression analysis demonstrated highly significant associations of kynurenine with GFR, hsCRP, and tryptophan, as well as a significant impact of age. Conclusions: This work speaks in favor of kynurenine being a new and valuable biomarker of CHF, with particular attention placed on its ability to predict mortality and reflect exercise capacity.

The role of catestatin (CST) in acutely decompensated heart failure (ADHF) and myocardial infarction (MI) is poorly elucidated. Due to the implicated role of CST in the regulation of neurohumoral activity, the goals of the study were to determine CST serum levels among ninety consecutively enrolled ADHF patients, with respect to the MI history and left ventricular ejection fraction (LVEF) and to examine its association with clinical, echocardiographic, and laboratory parameters. CST levels were higher among ADHF patients with MI history, compared to those without (8.94 ± 6.39 vs. 4.90 ± 2.74 ng/mL, p = 0.001). CST serum levels did not differ among patients with reduced, midrange, and preserved LVEF (7.74 ± 5.64 vs. 5.75 ± 4.19 vs. 5.35 ± 2.77 ng/mL, p = 0.143, respectively). In the multivariable linear regression analysis, CST independently correlated with the NYHA class (β = 0.491, p < 0.001), waist-to-hip ratio (WHR) (β = −0.237, p = 0.026), HbA1c (β = −0.235, p = 0.027), LDL (β = −0.231, p = 0.029), non-HDL cholesterol (β = −0.237, p = 0.026), hs-cTnI (β = −0.221, p = 0.030), and the admission and resting heart rate (β = −0.201, p = 0.036 and β = −0.242, p = 0.030), and was in positive association with most echocardiographic parameters. In conclusion, CST levels were increased in ADHF patients with MI and were overall associated with a favorable cardiometabolic profile but at the same time reflected advanced symptomatic burden (CATSTAT-HF ClinicalTrials.gov number, NCT03389386).

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 BACKGROUND New echocardiographic phenotypes of heart failure (HF) are focused on myocardial systolic involvement of the left ventricle (LV), either endocardial and/or transmural. PURPOSE. To study the pattern of myocardial involvement in patients (p) with HF with preserved left ventricular ejection fraction (pLVEF) and cardiac amyloidosis (CA). METHODS. Comparative study of 16 p with CA and HF with pLVEF, considering as cut point LVEF &gt; 50%, in NYHA class ≥ II / IV, and a control group of 16 healthy people. Longitudinal Strain (LS) and Circumferential Strain (CS) were calculated using 2D speckle-tracking echocardiography, along with Mitral Annulus Plane Systolic Excursion (MAPSE) and Base-Apex distance (B-A). Also, the following indexes were calculated: Twist (apical rotation + basal rotation, º); Classic Torsion (TorC): (twist/B-A, º/cm); Torsion Index (Tor.I): (twist/MAPSE, º/cm) and Deformation Index (Def.I): (twist/LS, º). We suggest the introduction of these dynamic torsion indexes as Tor.I and Def.I that include twist per unit of longitudinal systolic shortening of the LV instead of using TorC which is the normalisation of twist to the end-diastolic longitudinal diameter of the LV. RESULTS There were no differences of age between the groups (68.2 ± 11.5 vs 63.7 ± 2.8 years, p = 0.14). Global values of LS and CS were lower in p with CA indicating endocardial and transmural deterioration during systole, while TorC and Twist of the LV remained conserved in p with CA. However, there is an increase of dynamic torsion parameters such as Tor.I and Def.I that show an increased Twist per unit of longitudinal shortening of the LV in the CA group (Table). CONCLUSIONS In p with CA and HF with pLVEF, the impairment of LS and CS indicates endocardial and transmural systolic dysfunction. In these conditions, LVEF would be preserved at the expense of a greater dynamic torsion of the LV. Table LS (%) CS (%) Twist (º) TorC (º/cm) Tor.I (º/cm) Def.I (º/%) CA pLVEF (n = 16) -11.7 ± 4.2 17.2 ± 4.8 19.8 ± 8.3 2.5 ± 1.1 27.7 ± 13.5 -1.8 ± 0.9 Control Group (n = 15) -20.6 ± 2.5 22.7 ± 4.9 21.7 ± 6.1 2.7 ± 0.8 16.4 ± 4.7 -1.0 ± 0.3 p &lt; 0.001 &lt; 0.01 0.46 0.46 &lt; 0.01 &lt; 0.01 Dynamic Torsion Indexes and Classic Torion Parameters in pLVEF CA patients vs Control group.

Background: Health-related quality of life tools that better reflect the unique subjective perception of heart failure (HF) are needed for patients with this disorder. The aim of this study was to explore whether subjective satisfaction of HF patients about daily life may provide additional prognostic information with respect to clinical cardiological data. Methods: One hundred and seventy-eight patients (age 51 ± 9 years) with moderate to severe HF [New York Heart Association (NYHA) class 2.0 ± 0.7; left ventricular ejection fraction (LVEF) 29 ± 8%] in stable clinical condition underwent a standard clinical evaluation and compiled the Satisfaction Profile (SAT-P) questionnaire focusing on subjective satisfaction with daily life. Cox regression analysis was used to assess whether SAT-P factors (psychological functioning, physical functioning, work, sleep/eating/leisure, social functioning) had any prognostic value. Results: Forty-six cardiac deaths occurred during a median of 30 months. Patients who died had higher NYHA class, more depressed left ventricular function, reduced systolic blood pressure (SBP), increased heart rate (HR), and worse biochemistry (all p < 0.05). Among the SAT-P factors, only Physical functioning (PF) was significantly reduced in the patients who died ( p = 0.003). Using the best subset selection procedure, Resistance to physical fatigue (RPF) was selected from among the items of the PF factor. RPF showed independent predictive value when entered into a prognostic model including NYHA class, LVEF, SBP, and HR with an adjusted hazard ratio of 0.86 per 10 units increase (95% CI 0.75–0.98, p = 0.02). Conclusions: Patients’ dissatisfaction with physical functioning is associated with reduced long-term survival, after adjustment for known risk factors in HF. Given its user-friendly structure, simplicity, and significant prognostic value, the RPF score may represent a useful instrument in clinical practice.

Background: Hypertensive heart failure (HHF) is the commonest form of heart failure in Nigeria. There is paucity of data in Nigeria on 24-hour Holter electrocardiography (24-HHECG) and important predictors of arrhythmias among HHF patients. Objectives: To determine the 24-HHECG characteristics among HHF patients. To determine the clinical and echocardiographic predictors of arrhythmias detected using 24-HHECG among HHF patients. Methods: A total of 100 HHF patients as well as 50 age-matched and sex-matched apparently healthy controls were prospectively recruited over a period of 1 year. They all had baseline laboratory tests, echocardiography, and 24-HHECG. Results: Hypertensive heart failure patients had significantly higher counts of premature ventricular contractions (PVCs) than the controls ( P ≤ .001). Ventricular tachycardia (VT) was recorded in 29% of HHF patients as compared with controls who had no VT on 24-HHECG. The standard deviation of all normal to normal sinus RR intervals over 24 hours (SDNN) was abnormally reduced among HHF patients when compared with controls ( P = .046). There was positive correlation between atrial fibrillation (AF) and the following parameters: PVCs ( r = .229, P = .015), New York Heart Association (NYHA) ( r = .196, P = .033), and VT ( r = .223, P = .018). Following multiple linear regression, left ventricular ejection fraction (LVEF) ( P ≤ .001) and serum urea ( P = .037) were predictors of PVCs among HHF patients. Serum creatinine ( P ≤ .001), elevated systolic blood pressure (SBP) ( P = .005), and PVCs ( P ≤ .001) were important predictors of VT among HHF patients. Conclusions: Renal dysfunction and reduced LVEF were important predictors of ventricular arrhythmias. High counts of PVCs and elevated SBP were predictive of the occurrence of VT among HHF patients. The NYHA class and ventricular arrhythmias have a significant positive correlation with AF. The SDNN is reduced in HHF patients.

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.

ObjectivesN-terminal probrain natriuretic peptide (NT-proBNP) predicts mortality and the development of heart failure in hypertrophic cardiomyopathy (HCM). Mid-regional proatrial natriuretic peptide (MR-proANP) is a stable by-product of production of atrial natriuretic peptide. We sought to compare the prognostic value of MR-proANP and NT-proBNP in HCM.MethodsWe prospectively enrolled a cohort of patients with HCM from different European centres and followed them. All patients had clinical, ECG and echocardiographic evaluation and measurement of MR-proANP and NT-proBNP at inclusion.ResultsOf 357 patients enrolled, the median age was 52 (IQR: 36–65) years. MR-proANP and NT-proBNP were both independently associated with age, weight, New York Heart Association (NYHA) class, left ventricular ejection fraction (LVEF), wall thickness and left atrial dimension. During a median follow-up of 23 months, 32 patients had a primary end point defined as death (n=6), heart transplantation (n=8), left ventricular assist device implantation (n=1) or heart failure hospitalisation (n=17). Both NT-proBNP and MR-proANP (p<10–4) were strongly associated with the primary endpoint, and the areas under the receiver operating characteristic (ROC) curves for both peptides were not significantly different. However, in a multiple stepwise regression analysis, the best model for predicting outcome was NYHA 1–2 vs 3–4 (HR=0.35, 95% CI 0.16 to 0.77, p<0.01), LVEF (HR=0.96, 95% CI 0.94 to 0.98, p=0.0005) and MR-proANP (HR=3.77, 95% CI 2.01 to 7.08, p<0.0001).ConclusionsMR-proANP emerges as a valuable biomarker for the prediction of death and heart failure related events in patients with HCM.

Background: Left ventricular ejection fraction (LVEF) is the gold standard for evaluating heart failure (HF) in coronary artery disease (CAD) patients. It is an essential metric in categorizing HF patients as preserved (HFpEF), mid-range (HFmEF), and reduced (HFrEF) ejection fraction but differs, depending on whether the ASE/EACVI or ESC guidelines are used to classify HF.Objectives: We sought to investigate the effectiveness of using deep learning as an automated tool to predict LVEF from patient clinical profiles using regression and classification trained models. We further investigate the effect of utilizing other LVEF-based thresholds to examine the discrimination ability of deep learning between HF categories grouped with narrower ranges.Methods: Data from 303 CAD patients were obtained from American and Greek patient databases and categorized based on the American Society of Echocardiography and the European Association of Cardiovascular Imaging (ASE/EACVI) guidelines into HFpEF (EF &gt; 55%), HFmEF (50% ≤ EF ≤ 55%), and HFrEF (EF &lt; 50%). Clinical profiles included 13 demographical and clinical markers grouped as cardiovascular risk factors, medication, and history. The most significant and important markers were determined using linear regression fitting and Chi-squared test combined with a novel dimensionality reduction algorithm based on arc radial visualization (ArcViz). Two deep learning-based models were then developed and trained using convolutional neural networks (CNN) to estimate LVEF levels from the clinical information and for classification into one of three LVEF-based HF categories.Results: A total of seven clinical markers were found important for discriminating between the three HF categories. Using statistical analysis, diabetes, diuretics medication, and prior myocardial infarction were found statistically significant (p &lt; 0.001). Furthermore, age, body mass index (BMI), anti-arrhythmics medication, and previous ventricular tachycardia were found important after projections on the ArcViz convex hull with an average nearest centroid (NC) accuracy of 94%. The regression model estimated LVEF levels successfully with an overall accuracy of 90%, average root mean square error (RMSE) of 4.13, and correlation coefficient of 0.85. A significant improvement was then obtained with the classification model, which predicted HF categories with an accuracy ≥93%, sensitivity ≥89%, 1-specificity &lt;5%, and average area under the receiver operating characteristics curve (AUROC) of 0.98.Conclusions: Our study suggests the potential of implementing deep learning-based models clinically to ensure faster, yet accurate, automatic prediction of HF based on the ASE/EACVI LVEF guidelines with only clinical profiles and corresponding information as input to the models. Invasive, expensive, and time-consuming clinical testing could thus be avoided, enabling reduced stress in patients and simpler triage for further intervention.

Objective:Assessment of habitual physical activity (PA) in patients with heart failure.Methods:This study included 50 patients with heart failure (61.9 ± 4.0 yr). Seven days of PA were assessed by questionnaire (AQ), pedometer, and accelerometer and correlated with prognostic markers including VO2peak, percent left-ventricular ejection fraction, N-terminal pro-B-type natriuretic peptide, and New York Heart Association (NYHA) functional class.Results:Accelerometry showed a stronger correlation with VO2peak and NYHA class (R = .73 and R = −.68; p < .001) than AQ (R = .58 and R = −.65; p < .001) or pedometer (R = .52 and R = −.50; p < .001). In the multivariable regression model accelerometry was the only consistent independent predictor of VO2peak (p = .002). Moreover, when its accuracy of prediction was tested, 59% of NYHA I and 95% of NYHA III patients were correctly classified into their assigned NYHA classes based on their accelerometer activity.Conclusion:PA assessed by accelerometer is significantly associated with exercise capacity in patients with heart failure and is predictive of disease severity. The data suggests that PA monitoring can aid in evaluating clinical status.

Abstract Background Sacubitril/Valsartan has been shown to improve symptoms and outcomes in patients with heart failure (HF) reduced ejection fraction in a single large randomised controlled trial. However, real-world data on its effect is limited. Purpose Our centre operates a dedicated HF clinic for the initiation and titration of Sacubitril/Valsartan in suitable patients. We report on patient tolerability and incidence of adverse effects. We also assessed change in New York Heart Association (NYHA) class and left ventricular ejection fraction (LVEF) post-treatment, as well as HF hospitalisation and mortality at 6 months. Methods We conducted a retrospective review of all patients seen in the clinic between January 2016 to January 2019. Patient demographics and pre-initiation treatments were recorded. We compared NYHA class and LVEF category as measured by echocardiography, at initiation and post-titration to the maximum tolerated dose. Data on HF admissions were obtained from electronic hospital records and mortality from a national database. Results A total of 179 patients were initiated on Sacubitril/Valsartan and included in the study. Mean age was 71 years (41–90), and 138 (77%) were male. Half of the patient cohort (89) had an ischaemic aetiology. Prior to initiation, all patients were established on an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. Almost all were on a beta-blocker (99%) and mineralocorticoid receptor antagonist (98%). 56 patients (31%) had a Cardiac Resynchronisation Therapy (CRT) device and 31 (17%) had an Implantable Cardioverter-Defibrillator (ICD). Only 4 patients (2%) had to discontinue treatment completely due to an adverse reaction. Among them, 3 patients sustained an acute kidney injury (AKI) while 1 patient had increased breathlessness. 40 patients (22%) reported symptomatic hypotension which required dose reduction. 7 patients (4%) sustained an AKI. 2 patients reported a rash and 1 patient reported nausea. Figure 1 shows the change in NYHA class after establishment on Sacubitril/Valsartan. Data on change in LVEF post establishment of Sacubitril/Valsartan was available in 124 patients and is shown in figure 2. A total of 133 patients had completed titration of treatment by July 2018 and included in the analysis of 6-month outcome. 13 patients had one HF hospitalisation and all-cause mortality was 4.5% (6 patients). Only 1 patient had heart failure documented as the primary cause of death. Change in NYHA class and LVEF Conclusion In our cohort of well treated HF patients with reduced ejection fraction, 40% of patients experienced an improvement in NYHA class after establishment on Sacubitril/Valsartan while 35% of patients also experienced a significant improvement in LVEF. Treatment was well tolerated and the discontinuation rate was low when managed in a dedicated HF clinic focused on initiation of Sacubitril/Valsartan.
