Trends and Outcomes Associated With Bariatric Surgery and Pharmacotherapies With Weight Loss Effects Among Patients With Heart Failure and Obesity. Circ Heart Fail 2024; 17:e010453. [PMID: 38275114 DOI: 10.1161/circheartfailure.122.010453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 09/28/2023] [Indexed: 01/27/2024]
Abstract
BACKGROUND Utilization patterns of bariatric surgery among older patients with heart failure (HF), and the associations with cardiovascular outcomes, are not well known. METHODS Medicare beneficiaries with HF and at least class II obesity from 2013 to 2020 were identified with Medicare Provider Analysis and Review 100% inpatient files and Medicare 5% outpatient files. Patients who underwent bariatric surgery were matched to controls in a 1:2 ratio (matched on exact age, sex, race, body mass index, HF encounter year, and HF hospitalization rate pre-surgery/matched period). In an exploratory analysis, patients prescribed pharmacotherapies with weight loss effects (semaglutide, liraglutide, naltrexone-bupropion, or orlistat) were identified and matched to controls with a similar strategy in addition to HF medical therapy data. Cox models evaluated associations between weight loss therapies (as a time-varying covariate) and mortality risk and HF hospitalization rate (calculated as the rate of HF hospitalizations following index HF encounter per 100 person-months) during follow-up. RESULTS Of 298 101 patients with HF and body mass index ≥35 kg/m2, 2594 (0.9%) underwent bariatric surgery (45% men; mean age, 56.2 years; mean body mass index, 51.5 kg/m2). In propensity-matched analyses over a median follow-up of 4.7 years, bariatric surgery was associated with lower risk of all-cause mortality (HR, 0.55 [95% CI, 0.49-0.63]; P<0.001), greater reduction in HF hospitalization rate (rate ratio, 0.72 [95% CI, 0.67-0.77]; P<0.001), and lower atrial fibrillation risk (HR, 0.78 [95% CI, 0.65-0.93]; P=0.006). Use of pharmacotherapies with weight loss effects was low (4.8%), with 96.3% prescribed GLP-1 (glucagon-like peptide-1) agonists (semaglutide, 23.6%; liraglutide, 72.7%). In propensity-matched analysis over a median follow-up of 2.8 years, patients receiving pharmacotherapies with weight loss effects (versus matched controls) had a lower risk of all-cause mortality (HR, 0.82 [95% CI, 0.71-0.95]; P=0.007) and HF hospitalization rate (rate ratio, 0.87 [95% CI, 0.77-0.99]; P=0.04). CONCLUSIONS Bariatric surgery and pharmacotherapies with weight loss effects are associated with a lower risk of adverse outcomes among older patients with HF and obesity; however, overall utilization remains low.

Abstract
INTRODUCTION Increasing numbers of patients with advanced organ disease are being considered for bariatric and metabolic surgery (BMS). There is no prospective study on the safety of BMS in these patients. This study aimed to capture outcomes for patients with advanced cardiac, renal, or liver disease undergoing BMS. MATERIALS AND METHODS This was a multinational, prospective cohort study on the safety of elective BMS in adults (≥18 years) with advanced disease of the heart, liver, or kidney. RESULTS Data on 177 patients with advanced diseases of heart, liver, or kidney were submitted by 75 centres in 33 countries. Mean age and BMI was 48.56±11.23 years and 45.55±7.35 kg/m 2 , respectively. Laparoscopic sleeve gastrectomy was performed in 124 patients (70%). The 30-day morbidity and mortality were 15.9% ( n =28) and 1.1% ( n =2), respectively. Thirty-day morbidity was 16.4%, 11.7%, 20.5%, and 50.0% in patients with advanced heart ( n =11/61), liver ( n =8/68), kidney ( n =9/44), and multi-organ disease ( n =2/4), respectively. Cardiac patients with left ventricular ejection fraction less than or equal to 35% and New York Heart Association classification 3 or 4, liver patients with model for end-stage liver disease score greater than or equal to 12, and patients with advanced renal disease not on dialysis were at increased risk of complications. Comparison with a propensity score-matched cohort found advanced disease of the heart, liver, or kidney to be significantly associated with higher 30-day morbidity. CONCLUSION Patients with advanced organ disease are at increased risk of 30-day morbidity following BMS. This prospective study quantifies that risk and identifies patients at the highest risk.

Abstract
The current study aims to evaluate the effect of bariatric metabolic surgery (BMS) on the New York Heart Association (NYHA) class and left ventricular ejection fraction (LVEF) in patients with diagnosed heart failure (HF). Fourteen related articles with 217 patients were included in the final analysis. LVEF significantly improved after BMS in patients with HF with a mean difference of 7.78% (CI 95%: 3.72, 11.84, I2 = 83.75, p-value < 0.001). Also, the NYHA class significantly decreased after BMS with a mean difference of - 0.40 (CI 95%: - 0.62, - 0.19, I2: 47.03, p-value < 0.001). A total of 27 patients with obesity and HF were listed for cardiac transplantation after BMS. Of those, 20 patients successfully underwent heart transplantation after BMS.

Abstract
AIMS To perform a systematic review and meta-analysis to evaluate the impact of weight loss (WL) on the prognosis of overweight and obese patients with heart failure (HF). METHODS AND RESULTS We reviewed the literature up to 1 February 2023 from PubMed, Web of Science, Embase, Cochrane Library, and Chinese databases for cohort studies, and randomized controlled trials (RCTs). Data from eligible studies were extracted, and statistical analyses were performed using Review Manager 5.3. A total of 19 studies (involving 449 882 patients) were included in the systematic review and meta-analyses. The results showed that WL did not reduce the mortality and rehospitalization rates in overweight and obese HF patients, but could improve the quality of life (P = 0.002), cardiac function (P = 0.0001), and exercise capacity (P = 0.03). The subgroup analysis showed that WL from bariatric surgery (BS) reduced the risk of death (P < 0.00001), WL from medication or exercise was not significantly associated with the risk of death (P = 0.18), and WL was associated with a higher mortality in the subgroup with unspecified WL modality or unintentional WL (P < 0.00001). In addition, it did not reduce the risk of short-term rehospitalization (P = 0.11), but reduced the rehospitalization rates over the long-term (P = 0.03). CONCLUSION WL improves the long-term rehospitalization (>3 months), quality of life, cardiac function, and exercise capacity in overweight and obese HF patients. Although overall WL is not proven effective, subgroup analysis shows that BS can reduce mortality.

Abstract
BACKGROUND Limited data integrating waitlist and postheart transplant (HT) mortality have evaluated outcomes of left ventricular assist device (LVAD)-bridged strategy vs no LVAD according to patient characteristics. We evaluated waitlist and post-HT mortality in LVAD-bridged vs nonbridged patients based on body mass index (BMI). METHODS We included linked adults listed for HT in Organ Procurement and Transplant Network/United Network for Organ Sharing and patients receiving durable LVAD as bridge to HT or candidacy in Society of Thoracic Surgeons/Interagency Mechanical Circulatory Support databases (2010-2019). Using BMI at listing or LVAD implant, we categorized patients as underweight (<18.5 kg/m2), normal weight (18.5-24.99 kg/m2), overweight (25-29.99 kg/m2), and obese (≥30 kg/m2). Kaplan-Meier analysis and multivariable Cox proportional hazards models informed the effect of LVAD-bridged and nonbridged strategy by BMI on waitlist, post-HT, and overall mortality (including waitlist and post-HT mortality). RESULTS Among 11,216 LVAD-bridged and 17,122 nonbridged candidates, bridged candidates were more frequently obese (37.3% vs 28.6%) (p < 0.001). Multivariable analysis indicated increased waitlist mortality in LVAD-bridged vs nonbridged with overweight (Hazard ratio (HR) 1.18, 95% confidence interval (CI) 1.02-1.36) or obesity (HR 1.35, 95%CI 1.17-1.56) in comparison to normal weight candidates (HR 1.02, 95%CI 0.88-1.19) (p-interaction < 0.001). Post-transplant mortality was not statistically different in LVAD-bridged vs nonbridged patients across BMI categories (p-interaction = 0.26). There was a nonsignificant graded increase in overall mortality in LVAD-bridged with overweight (HR 1.53, 95%CI 1.39-1.68) or obesity (HR 1.61, 95%CI 1.46-1.78) compared to nonbridged patients (p-interaction = 0.13). CONCLUSIONS LVAD-bridged candidates with obesity had higher waitlist mortality compared to nonbridged candidates with obesity. Post-transplant mortality was similar in LVAD-bridged and nonbridged patients, but obesity remained associated with increased mortality in both groups. This study may aid clinicians and advanced heart failure patients with obesity in decision-making.

Abstract
BACKGROUND The role of metabolic and bariatric surgery (MBS), in synergy with left ventricular assist device (LVAD) implantation, in the scope of end-stage heart failure management for patients with severe obesity is not well elucidated. METHODS We conducted a meta-analysis using Cochrane, Embase, PubMed, and Scopus databases to include articles from their inception to November 2022. RESULTS A total of 271 patients who underwent MBS during or after the LVAD implantation were included from eleven separate studies. After surgery, 67.4% of patients were listed on the heart transplant waitlist with 32.5% undergoing a successful transplant. We reported a mean listing time of 13.8 months. Finally, the pooled postoperative complication rate, 30-day readmission rate, and one-year mortality rate were 47.6%, 23.6% and 10.2% respectively. CONCLUSIONS MBS and LVAD is a safe and effective approach to bridge patients with severe obesity and end-stage heart failure for definitive heart transplantation.

Abstract
PURPOSE OF REVIEW To describe the relationship between three pandemics: hypertension, obesity, and heart failure. From pathophysiology to treatment, understanding how these disease entities are linked can lead to breakthroughs in their prevention and treatment. The relevance of this review lies in its discussion of novel pharmacological and surgical treatment strategies for obesity and hypertension, and their role in the prevention and treatment of heart failure. RECENT FINDINGS Novel medications such as GLP-1 agonists have demonstrated sustained weight loss in patients with obesity, and concurrent improvements in their cardiometabolic profile, and possibly also reductions in hypertension-related comorbidities including heart failure. Surgical therapies including laparoscopic bariatric surgery represent an important treatment strategy in obese patients, and recent studies describe their use even in patients with advanced heart failure, including those with ventricular assist devices. SUMMARY These developments have deep implications on our efforts to understand, mitigate, and ultimately prevent the three pandemics, and offer promising improvements to quality of life, survival, and the cost burden of these diseases.

Body Composition and Risk of Incident Heart Failure in 1 Million Adults: A Systematic Review and Dose-Response Meta-Analysis of Prospective Cohort Studies. J Am Heart Assoc 2023; 12:e029062. [PMID: 37345755 PMCID: PMC10356078 DOI: 10.1161/jaha.122.029062] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Accepted: 05/15/2023] [Indexed: 06/23/2023]
Abstract
Background The aim of this systematic review was to quantify the associations between body composition measures and risk of incident heart failure (HF) and its subtypes in the general population. Methods and Results We searched Medline, Embase, and Global Health databases from each database inception to January 19, 2023 for prospective studies reporting on body composition and HF risk. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The Newcastle-Ottawa scale was used to assess the risk of bias of included studies. Fixed-effects models were used for meta-analysis. Thirty-five studies were included (ntotal=1 137 044; ncases=34 422). Summary relative risk (RR) per 5-kg/m2 higher body mass index was 1.42 (95% CI, 1.40-1.42; 𝜁2=0.02, I2=94.4%), 1.28 (95% CI, 1.26-1.31; 𝜁2=0.01, I2=75.8%) per 10-cm higher waist circumference, and 1.33 (95% CI, 1.28-1.37; 𝜁2=0.04, I2=94.9%) per 0.1-unit higher waist-hip ratio. Pooled estimates of the few studies that reported on regional fat suggested significant positive association between HF risk and both visceral fat (RR, 1.08 [95% CI, 1.04-1.12]) and pericardial fat (RR, 1.08 [95% CI, 1.06-1.10]). Among HF subtypes, associations were stronger for HF with preserved ejection fraction than HF with reduced ejection fraction. No study reported on lean mass. Conclusions Pooled data suggested strong associations between adiposity and HF. The association with adiposity is stronger for HF with preserved ejection fraction than HF with reduced ejection fraction, indicating that different mechanisms may be at play in etiopathogenesis of HF subtypes. Future studies are needed to investigate role of regional fat mass and lean mass in HF risk. Registration Information REGISTRATION: URL: www.crd.york.ac.uk/prospero/.

Abstract
BACKGROUND Bariatric surgery results in significant weight loss and a reduction in the incidence of cardiovascular disease in patients with obesity; however, relatively little research considers its effect on the incidence of heart failure (HF). We aimed to determine whether bariatric surgery reduces the incidence of HF in patients with obesity, compared to non-surgical management. METHODS A propensity-score matched, retrospective cohort study using patients records from the nationwide Clinical Practice Research Database (CPRD) was conducted. 3052 patients who received bariatric surgery were matched with 3052 patients who did not, according to propensity to receive bariatric surgery, determined through a logistic regression model. Patients were eligible if >18 years old, BMI > 35 kg/m2, and no prior diagnosis of HF. The pre-defined primary endpoint was the development of new HF, and secondary endpoints were all-cause mortality and hospitalisations due to HF. RESULTS Patients who received bariatric surgery had a significantly lower incidence of new HF (hazard ratio 0.45, 95% confidence interval 0.28-0.73, p = 0.0011) and all-cause mortality (hazard ratio 0.56, 95% confidence interval 0.38-0.83, p = 0.0036). CONCLUSIONS This study provides evidence of lower rates of HF and all-cause mortality in patients who undergo bariatric surgery, compared to propensity-score matched controls. Future studies to understand the mechanism(s) involved in this reduction and explore the lifetime benefits in high-risk cohorts are paramount.

Abstract
BACKGROUND Metabolic surgery has been shown to partially reverse metabolic and cardiovascular derangements associated with obesity. Using a national database, we examined the association of prior metabolic surgery with outcomes after elective cardiac operations. METHODS The 2016 to 2019 Nationwide Readmissions Database was queried to identify all adult hospitalizations for elective cardiac operations. Individual comorbidities and history of metabolic surgery were ascertained using International Classification of Diseases 10th Revision diagnosis codes. Entropy balancing was used to adjust for differences in baseline characteristics between patients with and without prior metabolic surgery. Multivariable logistic and linear regressions were subsequently developed to assess the association between metabolic surgery and in-hospital mortality, perioperative complications, length of stay, costs, and 30-day unplanned readmission. RESULTS An estimated 454,506 hospitalizations entailing elective cardiac operations met inclusion criteria, of whom 3,615 (0.80%) had a diagnosis code indicating a history of metabolic surgery. Compared to their counterparts, those with prior metabolic surgery were more frequently female, younger, and had a higher burden of comorbidities as measured by the Elixhauser Comorbidity Index. After adjustment, prior metabolic surgery was associated with significantly reduced mortality (adjusted odds ratio 0.50, 95% confidence interval 0.31-0.83). Prior metabolic surgery was also linked to decreased pneumonia, prolonged mechanical ventilation, and respiratory failure. Of note, patients with a history of metabolic surgery encountered a greater likelihood of 30-day, non-elective readmission (adjusted odds ratio 1.26, 95% confidence interval 1.08-1.48). CONCLUSIONS Patients with a history of metabolic surgery had significantly reduced odds of in-hospital mortality and perioperative complications after cardiac operations but faced increased readmissions.

Abstract
Heart failure (HF) remains one of the cardiovascular diseases (CVDs) associated with a high unmet medical need due to high morbidity and mortality rates and lack of efficacious interventions. HF is closely related to cardiometabolic diseases such as diabetes, obesity and chronic kidney disease, and strategies that address most or all these intertwined conditions are desirable. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are approved for type 2 diabetes (T2D), and some are also indicated for reduction of the risk of atherosclerotic CVD in T2D and for weight management. As we summarise in this concise review, preliminary evidence suggests that the cardioprotective benefits of GLP-1 RAs may also extend to HF. The most robust clinical evidence arguably originates from the large cardiovascular outcomes trials (CVOTs) completed for most GLP-1 RAs, of which the latest showed a significant relative risk reduction (RRR) of 39% (HR) with once-weekly efpeglenatide on HF requiring hospitalisation, corroborating a meta-analysis which found a significant RRR across eight GLP-1 RA CVOTs of 11%. Further, although incompletely described, multiple studies are available to provide insights into the mechanistic underpinnings, which appear to be associated mostly with indirect cardioprotective benefits owing to the ability of GLP-1 RAs to address hyperglycaemia, and reduce body weight, and, amongst others, inflammation. In sum, current evidence positions GLP-1 RAs as a potential cardioprotective strategy in HF, with HF with preserved ejection fraction emerging as the clinically most relevant phenotype for the drug class, especially when occurring in people with obesity with and without diabetes.

Abstract
INTRODUCTION Bariatric surgery (BS) is the most effective therapy for morbid obesity. Cortisol and DHEA are steroid hormones with opposing effects, thus using Cortisol/DHEA ratio (C/D) rather than the use of either hormone alone has been found to predict health outcomes more reliably. It was interesting to study C/D as an indicator of favorable metabolic and cardiovascular outcomes after BS. OBJECTIVE To assess C/D in morbidly obese patients before and after BS in relation to metabolic parameters and cardiovascular performance. PATIENTS AND METHODS Forty morbidly obese patients were followed prospectively for 1 year after BS. Fasting blood glucose (FBG), fasting insulin (FI), C/D, lipid profile, high-sensitive CRP (hs-CRP), and echocardiography were done before BS and at 3 months and 1 year post BS. RESULTS A total of 40 morbidly obese patients undergone sleeve gastrectomy. Blood pressure, FBG, FI, hs-CRP, C/D were significantly decreased after BS (p < 0.001). At 1 year post BS; significant reduction in left ventricular posterior wall thickness (LVPW) (p < 0.001), left ventricular mass (LVM) (p = 0.003), relative wall thickness (RWT) (p < 0.001) with a significant improvement in early diastolic velocity (E) (p < 0.001), early diastolic velocity/late diastolic velocity (E/A) (p = 0.01). After BS; C/D significantly positively correlated with FBG (p = 0.019), hs-CRP (p = 0.008), interventricular septum thickness (IVS) (p = 0.028), LVPW (p = 0.028), relative wall thickness (RWT) (p = 0.022), early diastolic velocity /early diastolic velocity (E') measured by pulsed tissue Doppler imaging (E/E') (p = 0.001), and significantly negatively correlated with E' (p = 0.032). C/D was the single significant independent variable affecting E' and E/E' post BS. CONCLUSION C/D can be used as a surrogate marker of the improved FBG and the resolution of inflammation post BS. C/D is an independent predictor of diastolic function improvement post BS.

Parallel improvement of systolic function with surgical weight loss in patients with heart failure and reduced ejection fraction: a systematic review and patient-level meta-analysis. Surg Obes Relat Dis 2021; 18:433-438. [PMID: 35058131 DOI: 10.1016/j.soard.2021.12.016] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 11/18/2021] [Accepted: 12/11/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Morbid obesity (MO) is an increasingly common condition in patients with heart failure with reduced ejection fraction (HFrEF). Although substantial weight loss in morbidly obese patients has proved to slow the progression of heart failure, parallel alteration of ejection fraction (EF) and New York Heart Association (NYHA) functional class along with post-bariatric surgery weight loss is yet to be determined. OBJECTIVES This systematic review aimed to measure the effect of bariatric weight loss on EF and NYHA functional class in patients with HFrEF. METHODS A systematic literature review was performed in Medline/PubMed to identify studies in patients with MO and pre-existing HFrEF, who underwent bariatric surgery. RESULTS A total of 11 studies encompassing 136 patients with HFrEF undergoing bariatric surgery for MO were included. Six studies provided patient-level data on 37 cases. Patients lost an average body mass index (BMI) of 12.9 ± 4.2 kg/m2 (5.1 to 23 kg/m2) after an average follow up of 22.43 ± 18.6 months (2-89 mo). There was a direct correlation between BMI loss and EF improvement (r = 0.61, P < .0001), but not between BMI loss and NYHA functional class changes (r = 0.17, P = .4). CONCLUSION Weight loss induced by bariatric surgery results in parallel EF increase in patients with MO and HFrEF. However, current data does not indicate a parallel improvement of clinical symptoms (NYHA functional class) along with such an increase in EF in this population of patients.

Abstract
Background Obesity increases and surgical weight reduction decreases the risk of atrial fibrillation (AF) and heart failure (HF). We hypothesized that surgically induced weight loss may favorably affect left atrial (LA) mechanical function measured by longitudinal strain, which has recently emerged as an independent imaging biomarker of increased AF and HF risk. Methods We retrospectively evaluated echocardiograms performed before and 12.2 ± 2.2 months after bariatric surgery in 65 patients with severe obesity (mean age 39 [36; 47] years, 72% of females) with no known cardiac disease or arrhythmia. The LA mechanical function was measured by the longitudinal strain using the semi-automatic speckle tracking method. Results After surgery, body mass index decreased from 43.72 ± 4.34 to 30.04 ± 4.33 kg/m2. We observed a significant improvement in all components of the LA strain. LA reservoir strain (LASR) and LA conduit strain (LASCD) significantly increased (35.7% vs 38.95%, p = 0.0005 and − 19.6% vs − 24.4%, p < 0.0001) and LA contraction strain (LASCT) significantly decreased (− 16% vs − 14%, p = 0.0075). There was a significant correlation between an increase in LASR and LASCD and the improvement in parameters of left ventricular diastolic and longitudinal systolic function (increase in E’ and MAPSE). Another significant correlation was identified between the decrease in LASCT and an improvement in LA function (decrease in A’). Conclusions The left atrial mechanical function improves after bariatric surgery. It is partially explained by the beneficial effect of weight reduction on the left ventricular diastolic and longitudinal systolic function. This effect may contribute to decreased risk of AF and HF after bariatric surgery. Graphical abstract ![]()

Abstract
Bariatric surgery may play a role in the management of morbidly obese patients with end-stage heart failure through increasing eligibility and improving the outcomes of destination therapies. We conducted a nationally representative, retrospective cohort study of patients with previous bariatric surgery undergoing either heart transplantation or left ventricular assist device implantation. Of 200 patients, < 6% experienced in-hospital mortality after destination therapy, comparable to that reported in the general population of heart recipients. Risk-adjusted outcomes differed minimally from those of obese patients undergoing destination therapy without previous bariatric surgery. This study provides important safety benchmarking data and demonstrates the feasibility of bariatric surgery as a potential bridge to left ventricular assist device implantation or heart transplantation in obese patients with end-stage heart failure.

Abstract
PURPOSE The aim of this study was to compare myocardial mechanics using global longitudinal strain (GLS) before and after single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S). MATERIALS AND METHODS A total of 21 obese patients undergoing SADI-S were prospectively included. Transthoracic echocardiography was performed before and after the procedure, and left ventricle (LV) and right ventricle (RV) strain was assessed by two-dimensional speckle-tracking imaging (2DST). RESULTS Mean time between pre-procedural and post-procedural echocardiograms was 9.2 ± 3.3 months. Postoperatively, %total weight loss (%TWL) was 33.0 ± 1.7 and % excess weight loss (%EWL) was 75.5 ± 3.6. Body mass index (BMI) significantly decreased after surgery (45.6 ± 1.2 vs 29.6 ± 1.0; p < 0.001). Postoperatively, LV GLS experienced a significant improvement (-19.8% ± 0.5 vs -22.2% ± 0.4; p < 0.001). Regarding other relevant functional parameters, RV free-wall strain was equally recovered (-19.1% ± 0.7 vs -21.0% ± 0.8; p 0.047). CONCLUSIONS This study demonstrates important and favourable changes in cardiac deformation parameters after performing SADI-S. Malabsorptive bariatric techniques such as SADI-S induce significant weight loss, leading to an improvement in subclinical myocardial function in patients with obesity.

Abstract
PURPOSE OF REVIEW To discuss clinical outcomes, changes in weight, and weight loss strategies of patients with obesity post left ventricular assist device (LVAD) implantation. RECENT FINDINGS Despite increased complications in patients with obesity after LVAD implantation, survival is comparable to patients without obesity. A minority of patients with obesity lose significant weight and become eligible for heart transplantation after LVAD implantation. In fact, a great majority of such patients gain weight post-implantation. Obesity by itself should not be considered prohibitive for LVAD therapy but, rather, should be incorporated into the overall risk assessment for LVAD implantation. Concerted strategies should be developed to promote sustainable weight loss in patients with obesity and LVAD to improve quality of life, eligibility, and outcomes after heart transplantation. Investigation of the long-term impact of weight loss on patients with obesity with LVAD is warranted.

Abstract
The obesity paradox, which suggests a survival advantage for the obese in heart failure (HF) has sparked debate in the medical community. Studies demonstrate a survival advantage in obese patients with HF, including those with advanced HF requiring continuous inotropic support for palliation or disease modifying therapy with a left ventricular assist device (LVAD) or heart transplantation (HT). Importantly, the obesity paradox is affected by the level of cardiorespiratory fitness (CRF). It is now recommended that HF patients with body mass index ≥35 kg/m2 achieve at least 5-10% weight loss, in order to improve symptoms and cardiac function, though more robust data are urgently needed. CRF may be the single best predictor of overall health and small improvements in fitness levels may lead to improved outcomes in HF. In addition to implications of obesity in chronic HF, we also discuss management of obese patients with advanced HF and their implications for therapies such as LVAD implantation and HT.
