Abstract
INTRODUCTION Bariatric surgery is effective in reversing adverse cardiac remodelling in obesity. However, it is unclear whether the three commonly performed operations; Roux-en-Y Gastric Bypass (RYGB), Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Adjustable Gastric Band (LAGB) are equal in their ability to reverse remodelling. METHODS Fifty-eight patients underwent CMR to assess left ventricular mass (LVM), LV mass:volume ratio (LVMVR) and LV eccentricity index (LVei) before and after bariatric surgery (26 RYGB, 22 LSG and 10 LAGB), including 46 with short-term (median 251-273 days) and 43 with longer-term (median 983-1027 days) follow-up. Abdominal visceral adipose tissue (VAT) and epicardial adipose tissue (EAT) were also assessed. RESULTS All three procedures resulted in significant decreases in excess body weight (48-70%). Percentage change in VAT and EAT was significantly greater following RYGB and LSG compared to LAGB at both timepoints (VAT:RYGB -47% and -57%, LSG -47% and -54%, LAGB -31% and -25%; EAT:RYGB -13% and -14%, LSG -16% and -19%, LAGB -5% and -5%). Patients undergoing LAGB, whilst having reduced LVM (-1% and -4%), had a smaller decrease at both short (RYGB: -8%, p < 0.005; LSG: -11%, p < 0.0001) and long (RYGB: -12%, p = 0.009; LSG: -13%, p < 0.0001) term timepoints. There was a significant decrease in LVMVR at the long-term timepoint following both RYGB (-7%, p = 0.006) and LSG (-7%, p = 0.021), but not LAGB (-2%, p = 0.912). LVei appeared to decrease at the long-term timepoint in those undergoing RYGB (-3%, p = 0.063) and LSG (-4%, p = 0.015), but not in those undergoing LAGB (1%, p = 0.857). In all patients, the change in LVM correlated with change in VAT (r = 0.338, p = 0.0134), while the change in LVei correlated with change in EAT (r = 0.437, p = 0.001). CONCLUSIONS RYGB and LSG appear to result in greater decreases in visceral adiposity, and greater reverse LV remodelling with larger reductions in LVM, concentric remodelling and pericardial restraint than LAGB.

Abstract
Abstract
Introduction
Cardiac geometry is affected by body composition, with total body adipose volume being related to left ventricular (LV) dilatation (due to increased intravascular volume and cardiac output), and visceral adipose tissue (VAT) to smaller LV cavity size and concentric remodelling (because of insulin resistance) [1]. As such we hypothesised that changes in VAT and total body weight during weight loss would have a differential impact on cardiac geometry. Alongside this, we hypothesised that, as the pericardium is a fixed volume, changes in epicardial adipose tissue (EAT), may have an additional mechanical effect by reducing pericardial restraint.
Purpose
We sought to investigate long term changes in VAT, total weight and EAT following bariatric surgery and relate them to changes in cardiac geometry.
Methods
Forty patients underwent cardiac magnetic resonance (CMR) imaging before and after bariatric surgery, including 21 who underwent short-term (median 209 days), 28 medium-term (median 428 days) and 12 long-term (median 1030 days) imaging follow up. Cardiac volumes (left atrial (LA), LV end-diastolic volume (LVEDV) and stroke volume (LVSV)) were assessed using cardiac MRI. VAT was assessed at L5 using a T1 weighted, water suppressed sequence. EAT volumes were calculated by manual contouring in end-ventricular systole on short axis slices from the mitral valve to the apex. Percentage changes in volumes were calculated between scans for each individual.
Results
Patients on average lost 32kg within the first 428 days following bariatric surgery (54% excess weight loss, p<0.0001), with no significant change in weight at the longer-term time point (Figure 1A). Most VAT loss occurred in the first 209 days (−42%, p<0.0001) with no subsequent change observed at the final two timepoints (Figure 1B). Similarly, EAT loss occurred in the first 209 days (−13%, mean 10ml, p<0.0001) with non-significant changes thereafter (Figure 1C).
There was a significant decrease in both LA (13%, mean 12ml, p<0.0001) and LVEDV (4%, mean 8ml, p=0.0249) at 209 days post-surgery. Both LA volume and LVEDV had returned to baseline by the longest term time point of 1030 days (Figure 2). LVSV followed a similar pattern being reduced at 209 days (by 10%, mean 9ml, p=0.0019), then returning to levels similar to those pre-weight loss at 1030 days (p=0.44) (Figure 2C).
Conclusions
Cardiac volumes show a biphasic response to weight loss, initially becoming smaller and then returning to baseline by 1030 days. We hypothesise that the early drop in LA and LV cavity size is a response to reduced volume from body mass reduction. In contrast, we propose that the increase in LA and LVEDV that follows results from the longer-term effects of reducing VAT, and increased space within the pericardium resulting from EAT loss allowing expansion to occur.

Background. Recent evidence shows epicardial adipose tissue (EAT) acts as a paracrine organ and may directly alter myocardial function by exerting mechanical compression.
Purpose. We evaluated EAT thickness through transthoracic echocardiography and investigated its relationship with cardiopulmonary fitness and cardiovascular haemodynamics at rest and during exercise in a population of heart failure (HF) patients with reduced (HFrEF) and preserved (HFpEF) ejection fraction.
Methods. We prospectively enrolled 393 consecutive HF outpatients (205 HFrEF, 188 HFpEF) who had been referred to our hospital due to dyspnoea and/or effort intolerance, together with 44 healthy controls. We performed a resting state-of-the-art echocardiographic evaluation, followed by combined cardiopulmonary-echocardiography exercise stress.
Results. EAT thickness was higher in HFpEF (median 8 mm, interquartile range [IQR] 4–12 mm) and progressively reduced in controls (median 5 mm, IQR 3–7 mm; p < 0.0001) and HFrEF (median 3 mm, IQR 2–6 mm). In HFpEF, EAT thickness was inversely correlated with peak oxygen consumption (VO2) and peripheral oxygen extraction (AVO2diff), while a direct association was observed for the same parameters in HFrEF (Figure 1). Furthermore, EAT independently predicted peak VO2 and AVO2diff in HFrEF and HFpEF regardless of body mass index and waist circumference. These relationships were direct in HFrEF (standard regression coefficient [SRC] for peak VO2: 0.18, p = 0.02; SRC for peak AVO2diff: 0.17, p = 0.03) and indirect in HFpEF (SRC for peak VO2: -0.33, p < 0.0001; SRC for peak AVO2diff: -0.25, p < 0.0001).
As there are no definite cut-off values to define increased EAT, patients were divided based on the median EAT value (5 mm) of the overall population. Thinner EAT (≤5 mm) was associated with worse LV systolic dysfunction (peak average S’) and remodeling (3D LV mass index) in HFrEF. In HFpEF, on the other hand, increased EAT (>5 mm) was related to worse right ventricular systolic dysfunction (3D right ventricular ejection fraction) and more severe left atrio-ventricular (left atrium reservoir strain/left ventricle global longitudinal strain) and right ventriculo-arterial (tricuspid annular plane systolic excursion/systolic pulmonary artery pressure) coupling (Figure 2).
Conclusion. In HFpEF, increased EAT thickness is associated with a worse hemodynamic profile and functional capacity. Conversely, in HFrEF, EAT thinning portends more advanced LV dysfunction and impaired cardiopulmonary fitness. Abstract Figure 1 Abstract Figure 2

Background. Recent evidence shows that increased epicardial adipose tissue (EAT) thickness is associated with metabolic syndrome, microvascular dysfunction and enhanced pericardial restraint.
Purpose. We measured echocardiography-derived EAT thickness in a population of heart failure (HF) patients with reduced (HFrEF) and preserved (HFpEF) ejection fraction to examine the relationship between EAT and prognosis at clinical follow-up.
Methods. We prospectively enrolled 393 consecutive HF outpatients (205 HFrEF, 188 HFpEF) who had been referred to our hospital due to dyspnoea and/or effort intolerance. We performed a resting clinical and biohumoral evaluation, followed by combined cardiopulmonary-echocardiography exercise stress. We considered a composite endpoint of cardiovascular death and HF-related hospitalization during follow-up.
Results. Patients with HFpEF displayed greater EAT thickness (median 8 mm, interquartile range [IQR] 4–12 mm) than HFrEF (median 3 mm, IQR 2–6 mm; p < 0.0001). During a median follow-up of 20.9 months (IQR 15-25 months), 34 cardiovascular deaths and 146 HF hospitalizations were reported, with no significant differences between the two HF phenotypes. EAT was shown to predict adverse events independently from body mass index, waist circumference and other well-established prognostic markers in HF (such as NT-proBNP and peak oxygen consumption). The risk of adverse events increased with increasing EAT thickness in HFpEF and with EAT thinning in HFrEF. Kaplan-Meier analyses for the composite endpoint showed that in HFpEF, the survival probability was significantly lower in patients with thicker EAT than those with thinner EAT. In HFrEF, conversely, patients with increased EAT thickness had a higher survival probability than those with reduced EAT thickness (Figure 1).
Conclusion. EAT accumulation is increased in HFpEF compared to HFrEF and carries different prognostic meanings in the two subsets. In HFpEF, EAT thickening portends adverse outcomes, which may be due to the secretion of pro-inflammatory and pro-atherogenic adipokines and increased mechanical restraint. In HFrEF, EAT thinning is associated with a worse prognosis, probably reflecting a more advanced catabolic state (e.g., cardiac cachexia). Larger studies are needed to determine whether or not EAT has a causal role in influencing progression and survival in the different HF phenotypes. Abstract Figure 1

Abstract
Aims This study aimed to describe haemodynamic features of patients with advanced heart failure with preserved ejection fraction (HFpEF) as defined by the Heart Failure Association (HFA) of the European Society of Cardiology (ESC). Methods and results We used pooled data from two dedicated HFpEF studies with invasive exercise haemodynamic protocols, the REDUCE LAP‐HF (Reduce Elevated Left Atrial Pressure in Patients with Heart Failure) trial and the REDUCE LAP‐HF I trial, and categorized patients according to advanced heart failure (AdHF) criteria. The well‐characterized HFpEF patients were considered advanced if they had persistent New York Heart Association classification of III–IV and heart failure (HF) hospitalization < 12 months and a 6 min walk test distance < 300 m. Twenty‐four (22%) out of 108 patients met the AdHF criteria. On evaluation, clinical characteristics and resting haemodynamics were not different in the two groups. Patients with AdHF had lower work capacity compared with non‐advanced patients (35 ± 16 vs. 45 ± 18 W, P = 0.021). Workload‐corrected pulmonary capillary wedge pressure normalized to body weight (PCWL) was higher in AdHF patients compared with non‐advanced (112 ± 55 vs. 86 ± 49 mmHg/W/kg, P = 0.04). Further, AdHF patients had a smaller increase in cardiac index during exercise (1.1 ± 0.7 vs. 1.6 ± 0.9 L/min/m2, P = 0.028). Conclusions A significantly higher PCWL and lower cardiac index reserve during exercise were observed in AdHF patients compared with non‐advanced. These differences were not apparent at rest. Therapies targeting the haemodynamic compromise associated with advanced HFpEF are needed.

Abstract
Abstract
Background
Patient-worn accelerometer is increasingly used in patients with heart failure and reduced ejection fraction (HFrEF) to assess daily activity and and as surrogate endpoint. We examined the association between cardiac physiology and daily activity by patient-worn accelerometer recordings in stable HFrEF patients.
Methods
In this descriptive study, physical average daily accelerometer units (PADA) and total average daily accelerometer unit (TADA) were assessed by a accelerometer recordings. Sixty three stable ambulatory patients with HFrEF, mainly men (92%), mean age 58±10 years, and ejection-fraction 26±4% underwent hemodynamic exercise testing, and accelerometry (Table 1). Patients were divided by PADA in a low and high activity level groups based on counts per minute physical activity.
Results
Patients in the low activity group were older and more frequently treated with diuretics. At rest, the low activity group was characterized by a lower cardiac index (CI) (2.2±0.4 vs. 2.4±0.4 l/min/m2, p=0.01), Stroke volume (SV) (70±19 vs. 81±17 ml, p=0.02) but not pulmonary capillary wedge pressure (PCWP) (12±5 vs. 11±5 mmHg, p=0.3) (Figure 1). Low activity group reached a lower CI (4.8±1.7 vs. 6.6±1.7 l/min/m2, p<0.001) and SV (94±32 vs. 121±29 ml, p<0.001), but not in PCWP (31±12 vs. 27±8 mmHg, p=0.2) or arterial-venous O2 content difference (A-VO2 diff) (13.00±2.32 vs. 12.96±1.65 ml O2/dl, p=0.9) at peak exercise. The attenuated increase was associated with attenuated increase in SV rther than increase in heart rate (42±23 vs. 52±21 bpm, p=0.07). Finally, CI at peak exercise was the only independent variable associated with PADA after adjusting for age, gender, and BMI (p<0.0001). The PADA and TADA were associated to functional assessments using Kansas City Cardiomyopathy Questionnaire, but not with New York Heart Association class or N-terminal pro brain natriuretic peptide (NT-proBNP) (Table 1).
Conclusion
Accelerometer-assessed activity in patients with HFrEF are associated with impairments in LV performance, SV reserve and cardiac output during exercise, to a greater extent than changes in arterial-venous O2 content difference or pulmonary vascular pressures. Accelerometer data may provide information about the functional status that we do not nessecary find in the widely used tools in both research and daily clinical practice.

Aims. We tested the prognostic role of a risk score including bio-humoral evaluation, cardiopulmonary-echocardiographic stress (CPET-ESE) and lung ultrasound, in patients with heart failure (HF) with reduced and preserved ejection fraction (HFrEF and HFpEF), and subjects at risk of developing HF (American College of Cardiology/American Heart Association Stages A and B).
Methods and results. We evaluated 318 subjects: 94 in Stages A-B, 194 in Stage C (85 HFpEF and 109 HFrEF), and 30 age and sex-matched controls (Stage 0). During a median follow-up of 18.5 months, we reported 40 urgent HF visits, 31 HF hospitalisations and 10 cardiovascular deaths. Cox proportional-hazards regression for predicting adverse events identified five independent predictors and each was assigned a number of points proportional to its regression coefficient: Δstress-rest B-lines >10 (3 points), peak oxygen consumption <16 mL/kg/min (2 points), minute ventilation/carbon dioxide production slope ≥36 (2 points), peak systolic pulmonary artery pressure ≥50 mmHg (1 point) and resting N-terminal pro-brain natriuretic peptide (NT-proBNP) >900 pg/mL (1 point). We defined three risk categories: low-risk (<3 points), intermediate-risk (3-6 points), and high-risk (>6 points). The event-free survival probability for these three groups were 93%, 52% and 20%, respectively. Hazard Ratio was 4.55 for each risk category upgrade (95% confidence interval [CI], 3.44-5.93). The area-under-curve for the scoring system to predict events was 0.92 (95% CI 0.88-0.96).
Conclusion. A multiparametric risk score including indices of exercise-induced pulmonary congestion, markers of cardiopulmonary dysfunction and NT-proBNP identifies patients at increased risk for HF events across the HF spectrum.

Aims. Combined cardiopulmonary exercise test (CPET) and exercise stress echocardiography (ESE) provides a non-invasive tool to study cardiopulmonary pathophysiology. We analyzed how cardiac functional reserve during exercise relates to peak oxygen consumption (VO2).
Methods and Results. We performed a symptom-limited graded ramp bicycle CPET-ESE in 30 healthy controls and 357 patients: 113 at risk of developing heart failure (American College of Cardiology/American Heart Association HF Stages A-B) and 244 in HF Stage C with preserved (HFpEF, n = 101) or reduced ejection fraction (HFrEF, n = 143). Peak VO2 significantly decreased from controls to Stage A-B and Stage C (Table 1). A multivariable regression model to predict peak VO2 revealed peak left ventricular systolic annulus tissue velocity (S"), peak TAPSE/PAPs (tricuspid annular plane systolic excursion/systolic pulmonary artery pressure) and low-load left atrial reservoir strain/E/e’ were independent predictors, in addition to peak heart rate, stroke volume and workload (adjusted R²=0.76, p < 0.0001). The model was successfully tested in subjects with atrial fibrillation (n = 49), and with (n = 224) and without (n = 163) beta-blockers (all p < 0.01). Peak S’ showed the highest accuracy in predicting peak VO2 < 10 mL/kg/min (cut-point ≤ 7.5 cm/s; AUC = 0.92, p < 0.0001) and peak VO2 > 20 mL/kg/min (cut-point > 12.5 cm/s; AUC = 0.84, p < 0.0001) in comparison to the other cardiac variables of the model (p < 0.05).
Conclusions. A model incorporating different measures of cardiac mechanics is strongly related to peak aerobic capacity and may help in identifying different causes of effort intolerance from HF Stage A to C.

Abstract
Abstract
Background
Heart failure (HF) is a debilitating disease and is associated with significant morbidity and mortality, and costs to health care systems. Monitoring the impact of therapy remotely holds the potential to reduce HF-related hospitalizations, improve quality of life, and optimize the use of the limited resources. Voice signal is an emerging non-invasive biomarker that has been associated with a number of disease states. We previously identified a significant relationship between specific vocal biomarkers and coronary artery disease, and recently extended these observations by showing that a pre-specified voice biomarker was associated with increased mortality and re-hospitalization in patients with HF.
Purpose
In the current study, we evaluated the association between a vocal biomarker derived from voice signal analysis and invasively measured indices of pulmonary hypertension (PH). We hypothesized that the pre-specified voice biomarker might be associated with hemodynamic indices reflective of PH that are known to be linked to HF-severity, and that predict outcomes such as HF-related hospitalization and death.
Methods
The study population included patients referred for an invasive cardiac hemodynamic study between January 2017 and December 2018. Subjects had their voice signal recorded to their smartphone on three separate occasions prior to the cardiac study. A pre-established numeric vocal biomarker was derived from each recording, and the mean vocal biomarker calculated for each patient. Patients were a priori divided into two groups: those with high pulmonary arterial pressure (PAP) defined as ≥35 mmHg consistent with moderate or greater PH, versus those with a lower PAP.
Results
Eighty three patients, mean age 61.6±15.1 years, 37 (44.6%) male, were included in the study. The intraclass correlation coefficient for the vocal biomarker in all patients was 0.83 implying very good agreement between values. Patients with a high mean PAP (≥35 mmHg) had significantly higher values of the voice biomarker compared to those with a lower mean PAP (0.74±0.85 vs. 0.43±0.86, p=0.008). Patients with a high pulmonary vascular resistance (PVR) defined as a PVR ≥1.7 Wood Units had significantly higher values of the voice biomarker compared to those with a lower PVR (0.62±0.83 vs. 0.33±0.90, p=0.026). Multivariable logistic regression showed that an increase in the voice biomarker by 1 unit was significantly associated with a high PAP, odds ratio (OR) 2.31, 95% CI 1.05–5.07, p=0.038, and with borderline significance with a high PVR, OR 2.14, 95% CI 0.94–4.87, p=0.07.
Conclusion
The current study shows a relationship between a noninvasive vocal biomarker derived from voice signal analysis and invasively derived hemodynamic indices related to PH obtained during cardiac catheterization. These results may have important and practical clinical implications for telemedicine and remote monitoring of patients with HF and PH.

Abstract
Abstract
Background
Mild to moderate mitral regurgitation (MR) is a common finding in heart failure with preserved ejection fraction (HFpEF). MR is often considered to be an innocent bystander, yet little data is available regarding its implications.
Aim
Determine the pathophysiologic correlates of MR in HFpEF
Methods
We retrospectively studied 280 patients with invasively proven HFpEF. MR was absent (None or trivial) in 163 subjects (Non-MR-HFpEF), and present in 117 (MR-HFpEF; 78 mild and 39 moderate MR). 247 subjects also underwent invasive cardiopulmonary exercise testing.
Results
At rest, MR-HFpEF subjects displayed higher pulmonary artery pressures (PAP), PCWP, and pulmonary vascular resistance (PVR; Table). During exercise, PAP and PCWP were not significantly different among groups, but MR-HFpEF displayed reduced ability to enhance cardiac output (CO) in response to heightened metabolic demand (oxygen consumption, VO2; Figure).

CO change in response to VO2 increase
Conclusion
The presence of even mild MR in HFpEF is associated with more adverse hemodynamics, greater pulmonary vascular dysfunction and impaired CO reserve with exercise. Further study is required to better understand the natural history and treatment for MR in HFpEF.

Abstract
OBJECTIVE To evaluate the stress neurohumoral and cardiac biomarker profile of patients with apical ballooning syndrome (ABS). METHODS Plasma-free metanephrines, B-type natriuretic peptide (BNP), high sensitivity C-reactive protein (hsCRP) and troponin T, as well as 24-hour urine catecholamines, metanephrines and free cortisol were measured in 19 ABS and 10 ST-elevation myocardial infarction (STEMI) patients. RESULTS An antecedent stressful event was identified in 15 ABS patients. There were no differences in plasma normetanephrine (median 0.64 (IQ range 0.43-0.97) nmol/l vs 0.53 (0.32-0.77) nmol/l, p = 0.44), metanephrine (0.10 (0.10-0.22) nmol/l vs 0.16 (0.10-0.38) nmol/l, p = 0.29), or cortisol levels (16.0 (7.3-44.0) microg/dl vs 13.0 (10.5-23.5) microg/dl, p = 0.95) between ABS and STEMI patients. The 24-hour urine metanephrines, catecholamines and cortisol levels were normal in the majority of ABS patients. Troponin T levels were lower (0.62 (0.18-0.84) ng/ml vs 3.80 (2.04-6.57) ng/ml, p<0.001), but BNP levels were higher in ABS compared with STEMI (944 (650-2022) pg/ml vs 206 (140-669) pg/ml, p = 0.009). HsCRP was similarly elevated in the two groups (11.0 (5.1-110.8) mg/l and 24.3 (8.1-88.6) mg/l, p = 0.78). CONCLUSIONS Catecholamine and cortisol levels were not elevated in our cohort of ABS, suggesting that routine measurement of these stress hormones is unlikely to be of diagnostic value in practice. In contrast to STEMI, ABS is characterised by a greater elevation in BNP and less myonecrosis.

Abstract
BACKGROUND Severe tricuspid regurgitation, constrictive pericarditis and restrictive cardiomyopathy can all present with signs and symptoms of right heart failure and similar haemodynamic findings of elevation and equalisation of diastolic pressures at catheterisation. Although catheterisation findings of enhancement of ventricular interaction are a reliable parameter to distinguish constrictive pericarditis from restrictive cardiomyopathy, this also may be present in severe tricuspid regurgitation. OBJECTIVE To identify unique haemodynamic parameters that differentiate severe tricuspid regurgitation from constrictive pericarditis. METHODS Haemodynamic findings from simultaneous right and left heart catheterisation of 14 patients (age 59 years; men 71%) with documented severe tricuspid regurgitation (group I) were compared with those of 14 patients with surgically proven constrictive pericarditis (group II). RESULTS Findings of elevated right atrial pressure, early rapid ventricular filling and expiratory equalisation of ventricular diastolic pressures were similar in both groups. Ventricular interdependence, assessed by interaction of left ventricular (LV) and right ventricular (RV) systolic pressures, was also present in both groups. Relative changes in LV and RV diastolic pressures during respiration reliably distinguished group I from group II. During inspiration, the difference between the LV and RV diastolic pressures widened in group I but narrowed in group II. The height and slope of the early rapid filling wave in RV pressure trace was accentuated during inspiration in group I but did not change in group II. CONCLUSIONS The haemodynamic findings at cardiac catheterisation in patients with severe, symptomatic tricuspid regurgitation are similar to those of constrictive pericarditis. Careful analysis of the relationship of the LV and RV diastolic pressures during respiration can help differentiate the two entities.
