Guerrero EL, Hobble BA, Russell SD. Exercise and weight loss with a left ventricular assist device: A case report and review of the literature. Curr Probl Cardiol 2024; 49:102753. [PMID: 39079618 DOI: 10.1016/j.cpcardiol.2024.102753] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2024] [Accepted: 07/23/2024] [Indexed: 08/06/2024]
Abstract
With changes in the heart transplant allocation system in the United States, the use of left ventricular device therapy (LVAD) as a bridge to transplant has decreased. Currently, one of the primary reasons to implant a device is for patient support until they can lose weight to qualify for transplant. This paper reviews the outcomes of various weight loss strategies for patients with LVADs including weight reduction surgery and cardiac rehab. Additionally, results of the use of GLP1 agonists on weight loss in general and in heart failure patients is reviewed. Finally, because of the unique issues involving exercise for patients with LVADs, we review safe exercise techniques with instructions for patients.

Abstract
Obesity is a risk factor for kidney, liver, heart, and pulmonary diseases, as well as failure. Solid organ transplantation remains the definitive treatment for the end-stage presentation of these diseases. Among many criteria for organ transplant, efficient management of obesity is required for patients to acquire transplant eligibility. End-stage organ failure and obesity are 2 complex pathologies that are often entwined. Metabolic and bariatric surgery before, during, or after organ transplant has been studied to determine the long-term effect of bariatric surgery on transplant outcomes. In this review, a multidisciplinary group of surgeons from the Society of American Gastrointestinal and Endoscopic Surgeons and the American Society for Transplant Surgery presents the current published literature on metabolic and bariatric surgery as a therapeutic option for patients with obesity awaiting solid organ transplantation. This manuscript details the most recent recommendations, pharmacologic considerations, and psychological considerations for this specific cohort of patients. Since level one evidence is not available on many of the topics covered by this review, expert opinion was implemented in several instances. Additional high-quality research in this area will allow for better recommendations and, therefore, treatment strategies for these complex patients.

Abstract
For adults with advanced heart failure, class II/III obesity (body mass index ≥35 kg/m2) represents major challenges, and it is even considered a contraindication for heart transplantation (HT) at many centers. This has led to growing interest in preventing and treating obesity to help patients with advanced heart failure become HT candidates. Among all weight-loss strategies, bariatric surgery (BSx) has the greatest weight loss efficacy and has shown value in enabling select patients with left ventricular assist devices (LVADs) and obesity to lose sufficient weight to access HT. Nevertheless, both BSx and antiobesity medications warrant caution in the LVAD population. In this review, the authors describe and interpret the available published reports on the impact of obesity and weight-loss strategies for patients with LVADs from general and HT candidacy standpoints. The authors also provide an overview of the journey of LVAD recipients who undergo BSx and review major aspects of perioperative protocols.

[PMID: 38583888 DOI: 10.1016/j.gassur.2024.02.013] [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: 11/10/2023] [Revised: 02/01/2024] [Accepted: 02/03/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Obesity is an independent risk factor for heart failure (HF). Substantial weight loss has been shown to reverse obesity-related cardiomyopathy. This study aimed to report our institution's experience with laparoscopic sleeve gastrectomy (LSG) in patients with morbid obesity and end-stage HF. METHODS Between 2018 and 2022, 26 patients with end-stage HF were referred for LSG. Of 26 patients, 16 underwent an operation, and 10 did not. After institutional review board approval, a retrospective electronic medical record review was performed to evaluate (i) age, (ii) preoperative weight, (iii) decrease in body mass index (BMI) score, (iv) whether the patient underwent heart transplantation, and (v) mortality. Data analysis was performed using Stata/SE (version 17.0; StataCorp). The Wilcoxon rank-sum test was used to compare continuous variables between the cohorts, and the Pearson chi-square test was used for binary variables with Bonferroni correction applied. RESULTS The LSG and non-LSG cohorts had comparable ages (P = .088) and starting BMI score (P = .918), and a proportion of patients had a ventricular assist device (P = .191). Patients who underwent LSG lost significantly more weight than the patients who did not, with an average decrease in BMI score of 8.9 kg/m2 (SD, ±6.13) and 1.1 kg/m2 (SD, ±4.10), respectively (P = .040). Of note, 6 patients (37.5%) who underwent LSG eventually underwent transplantation, compared with 2 patients (20.0%) from the matched cohort (P = .884). Of the 26 patients, there were 6 deaths: 2 (12.5%) in the LSG cohort and 4 (40.0%) in the non-LSG cohort (P = .525). CONCLUSION LSG may be safe and effective for weight loss in patients with HF. This operation may provide patients affected by obesity with end-stage HF the lifesaving opportunity to achieve transplant candidacy.

Abstract
BACKGROUND Heart transplantation is relatively contraindicated in morbidly obese patients because of increased morbidity and mortality. This study identified risk factors for post-heart transplantation mortality in obese patients with a left ventricular assist device (LVAD). METHODS The United Network for Organ Sharing database was used to identify patients with a body mass index ≥35 kg/m2 who had a durable LVAD at the time of isolated heart transplantation between 2010 and 2021. The primary outcome was post-heart transplantation 1-year mortality. Multivariable Cox regression modeling was used to identify significant risk factors for 1-year mortality. Receiver-operating characteristic analyses were performed to identify optimal thresholds for continuous variables associated with the primary outcome. Patients were stratified by the number of risk factors, and Kaplan-Meier analysis was used to compare survival. RESULTS A total of 1222 obese patients were bridged to heart transplantation with a durable LVAD. Six risk factors were identified as significantly associated with 1-year post-heart transplantation mortality: recipient age >62.5 years, body mass index >36.6 kg/m2, bilirubin level >0.95 mg/dL, cold ischemic time >3.7 hours, recipient-donor sex mismatch, and pretransplantation mechanical ventilation. The distribution of cumulative risk factors was as follows: 8.6% with 0, 30.6% with 1, 37.0% with 2, and 23.8% patients with ≥3 risk factors. The 1-year survival rate decreased significantly from 96.0% in those patients with 0 risk factors to 77.6% in those with 3 or more risk factors. CONCLUSIONS These data provide a useful guide for risk stratification and patient selection in obese LVAD candidates being considered for heart transplantation.

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
INTRODUCTION Patients suffering from advanced heart failure may undergo left ventricular assist device (LVAD) placement as a bridge to cardiac transplantation. However, those with a BMI above 35 kg/m2 are generally not considered eligible for transplant due to their elevated cardiac risk. We review our experience with bariatric surgery in this high-risk population to assess its safety and efficacy in reducing BMI to permit cardiac transplantation. METHODS We retrospectively reviewed all patients on durable LVAD support who underwent sleeve gastrectomy (SG) at Mount Sinai Hospital between August 2018 and December 2022. Electronic medical records were reviewed to analyze patient demographics, surgical details, and outcomes regarding weight loss and heart transplantation. RESULTS We identified twelve LVAD patients who underwent SG. Three were performed laparoscopically and 9 via robotic approach. Four patients (33.3%) underwent an orthotopic heart transplant (OHTx). Half of these patients were female. For patients who underwent OHTx, mean age at LVAD placement was 41.0 (R30.6-52.2), at SG was 43.9 (R32.7-55.0) and at OHTx was 45.3 years (R33.3-56.8). Mean BMI increased from 38.8 at LVAD placement to 42.5 prior to SG. Mean time from SG to OHTx was 17.9 months (R6-7-27.5) during which BMI decreased to mean 32.8 at the time of OHTx. At most recent follow-up, mean BMI was 31.9. All patients were anticoagulated prior to surgery; one required return to the operating room on post-operative day 1 after SG for bleeding and one was re-admitted on post-operative day 7 for hematochezia treated conservatively. CONCLUSION SG is a safe and effective operation in patients with severe obesity and heart failure requiring an LVAD. 66.7% of our cohort achieved target BMI < 35 and 33.3% underwent heart transplantation. Longer term follow-up is needed to clarify full bridge-to-transplant rate and long-term survival outcomes.

Abstract
BACKGROUND Many patients with heart failure (HF) are denied cardiac transplants due to inability to meet transplantation body mass index (BMI) criteria. Bariatric intervention, including surgery, medication, and weight loss guidance, may help patients lose weight and become eligible for transplantation. OBJECTIVE We aim to contribute to the literature on the safety and efficacy of bariatric intervention on patients with obesity and HF who are awaiting cardiac transplantation. SETTING University hospital, United States. METHODS This was a mixed retrospective/prospective study. Eighteen patients with HF and BMI >35 kg/m2 were reviewed. Patients were divided based on whether they underwent bariatric surgery or nonsurgical intervention and whether they had left ventricular assist devices or other advanced heart failure therapy including inotropic support, guideline-directed medical therapy, and/or temporary mechanical circulatory support. Weight, BMI, and left ventricular ejection fraction (LVEF) were collected before bariatric intervention and 6 months after bariatric intervention. RESULTS No patients were lost to follow-up. Bariatric surgery led to statistically significant decreases in weight and BMI when compared with nonsurgical patients. At 6 months after intervention, surgical patients lost an average of 18.6 kg and decreased their BMI by 6.4 kg/m2 while nonsurgical patients lost 1.9 kg and decreased their BMI by .7 kg/m2. After bariatric intervention, surgical patients had an average LVEF increase of 5.9% and nonsurgical patients had an average decrease of 5.9%, although these findings lacked statistical significance. CONCLUSION Our study suggests that bariatric intervention among patients with HF and obesity is a safe and effective method of weight and BMI reduction.

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
Left ventricular assist device (LVAD) implantation leads to improvement in symptoms and survival in patients with advanced heart failure. An important factor in improving outcomes post-LVAD implantation is optimal preoperative patient selection and optimization. In this review, we highlight the latest on the evaluation of patients with advanced heart failure for LVAD candidacy, including discussion of patient selection, implantation timing, laboratory and other testing considerations, and the importance of psychosocial evaluation. Such thorough evaluation by multidisciplinary team can serve to improve the outcomes of a complex group of patients with advanced heart failure being evaluated for LVAD.

Abstract
PURPOSE OF REVIEW Left ventricular assist devices (LVADs) are life-saving therapies for patients in end-stage heart failure (HF) with reduced ejection fraction regardless of candidacy for heart transplantation. Multiple clinical trials have demonstrated improved morbidity and mortality with LVADs when compared to medical therapy alone. However, the uptake of LVADs as a therapeutic option in a larger section of end-stage HF patients remains limited, partly due to associated adverse events and re-hospitalization. RECENT FINDINGS Accurate assessment and staging of HF patients is crucial to guide appropriate use of LVADs. Innovative methods to risk stratify patients and manage cardiac and noncardiac comorbidities can translate to improved outcomes in LVAD recipients. Inclusion of quality of life metrics and measurements of adverse events can better inform heart failure cardiologists to help identify ideal LVAD candidates. Addition of machine learning algorithms to this process may guide patient selection to improve outcomes. SUMMARY Patient selection and assessment of reversible medical comorbidities are critical to the postoperative success of LVAD implantation. Identifying patients most likely to benefit and least likely to experience adverse events should be a priority.

Obesity and outcomes after left ventricular assist device implantation-insights from the EUROMACS registry. Eur J Cardiothorac Surg 2022; 62:6650624. [PMID: 35894678 DOI: 10.1093/ejcts/ezac401] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 06/07/2022] [Accepted: 07/25/2022] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVES The objective was to analyze associations between obesity and outcomes after left ventricular assist device implantation. METHODS A retrospective analysis of the EUROMACS Registry was performed. Adult patients undergoing primary implantation of a continuous-flow left ventricular assist device between 2006 and 2019 were included (Medtronic HeartWare® HVAD®, Abbott HeartMate II®, Abbott HeartMate 3™). Patients were classified in 4 different groups according to body mass index at the time of surgery (body mass index < 20 kg/m2: n = 254; 20-24.9 kg/m2: n = 1281; 25-29.9 kg/m2: n = 1238; ≥ 30 kg/m2: n = 691). RESULTS The study cohort was comprised of 3464 patients. Multivariable Cox proportional cause-specific hazards regression analysis demonstrated that obesity (body mass index ≥ 30 kg/m2) was independently associated with significantly increased risk of mortality (body mass index "≥ 30" vs "20-24.9" kg/m2: hazard ratio 1.36, 95% confidence interval 1.18 to 1.57, overall p < 0.001). Moreover, obesity was associated with significantly increased risk of infection and driveline infection. The probability to undergo heart transplantation was significantly decreased in obese patients (body mass index "≥ 30" vs "20-24.9" kg/m2: hazard ratio 0.59, 95% confidence interval 0.48 to 0.74, overall p < 0.001). CONCLUSIONS Obesity at the time of left ventricular assist device implantation is associated with significantly higher mortality and increased risk of infection as well as driveline infection. The probability to undergo heart transplantation is significantly decreased. These aspects should be considered when devising a treatment strategy before surgery.

Clinical Outcomes, Trends in Weight, and Weight Loss Strategies in Patients With Obesity After Durable Ventricular Assist Device Implantation. Curr Heart Fail Rep 2021; 18:52-63.

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.
