RESUMEN
BACKGROUND: Peripheral arterial disease (PAD) is associated with comorbid conditions and frailty. The role of preoperative nutrition in patients with PAD has not been well characterized. In the present scoping review, we sought to describe the prevalence and prognostic implications of preoperative malnutrition in patients undergoing vascular interventions for claudication or chronic limb-threatening ischemia (CLTI). METHODS: We systematically searched for studies across six databases from inception to August 2021. Studies that had focused on patients with claudication or CLTI who had undergone open or endovascular procedures were included if preoperative nutrition had been measured and correlated with a clinical outcome. RESULTS: Of 4186 records identified, 24 studies had addressed the prevalence or prognostic effects of malnutrition in patients who had undergone interventions for PAD. The proportion of women included in these studies ranged from 6% to 58%. The prevalence of preoperative malnutrition ranged from 14.6% to 72%. Seven different malnutrition assessments had been used in these studies. Across all the scales, preoperative malnutrition was associated with at least one of the following outcomes: mortality, postoperative complications, length of stay, readmission rates, and delayed wound healing. CONCLUSIONS: A variety of tools were used to measure malnutrition in patients undergoing interventions for PAD. Our findings suggest that preoperative malnutrition is associated with adverse clinical outcomes for patients undergoing open and endovascular procedures for claudication or CLTI and that consensus is lacking regarding which tool to use. Clinicians and surgeons should be sensitized to the importance of assessing for malnutrition preoperatively in adults undergoing interventions for PAD.

BACKGROUND: Few studies have measured frailty as a potential reason for foregoing transcatheter aortic valve replacement (TAVR) in older adults with severe aortic stenosis (AS). This study sought to determine the impact of frailty and other clinician-cited reasons on restricted mean survival time (RMST). METHODS: An analysis of the McGill Frailty Registry was conducted between 2014 and 2018 at the McGill University Health Center Structural Valve Clinic. Consecutive nonsurgical patients referred for TAVR were included. In those that underwent balloon aortic valvuloplasty or medical management, the primary clinician-cited reason for foregoing TAVR was codified. Vital status was ascertained at 1 year and analysed using RMST and Kaplan-Meier analyses. RESULTS: The study consisted of 373 patients with a mean age of 82.4 years, of which 233 underwent TAVR and 140 did not. Patients who did not undergo TAVR were more likely to be nonagenarians, with left ventricular dysfunction, chronic kidney disease, dementia, disability, depression, malnutrition, and frailty. The primary clinician-cited reason was: comorbidity in 34%, frailty in 23%, procedural feasibility and risks in 16%, and mild or unrelated symptoms in 27%. Compared to the TAVR group, 1-year RMST was reduced by 2.0 months in the medical management group (95% CI 1.2, 2.7) and by 1.1 months in the valvuloplasty group (95% CI -0.2, 2.5). CONCLUSIONS: Patients with severe AS referred for TAVR may never undergo the procedure on the basis of comorbidity, frailty, procedural issues, and symptoms. The best treatment decision is one that follows from multi-disciplinary assessment encompassing frailty.

Importance: Osteosarcopenia is an emerging geriatric syndrome characterized by age-related deterioration in muscle and bone. Despite the established relevance of frailty and sarcopenia among older adults undergoing transcatheter aortic valve replacement (TAVR), osteosarcopenia has yet to be investigated in this setting. Objective: To determine the association between osteosarcopenia and adverse outcomes following TAVR. Design, Setting, and Participants: This is a post hoc analysis of the Frailty in Aortic Valve Replacement (FRAILTY-AVR) prospective multicenter cohort study and McGill extension that enrolled patients aged 70 years or older undergoing TAVR from 2012 through 2022. FRAILTY-AVR was conducted at 14 centers in Canada, the United States, and France between 2012 and 2016, and patients at the McGill University-affiliated center in Montreal, Québec, Canada, were enrolled on an ongoing basis up to 2022. Exposure: Osteosarcopenia as measured on computed tomography (CT) scans prior to TAVR. Main Outcomes and Measures: Clinically indicated CT scans acquired prior to TAVR were analyzed to quantify psoas muscle area (PMA) and vertebral bone density (VBD). Osteosarcopenia was defined as a combination of low PMA and low VBD according to published cutoffs. The primary outcome was 1-year all-cause mortality. Secondary outcomes were 30-day mortality, hospital length of stay, disposition, and worsening disability. Multivariable logistic regression was used to adjust for potential confounders. Results: Of the 605 patients (271 [45%] female) in this study, 437 (72%) were octogenarian; the mean (SD) age was 82.6 (6.2) years. Mean (SD) PMA was 22.1 (4.5) cm2 in men and 15.4 (3.5) cm2 in women. Mean (SD) VBD was 104.8 (35.5) Hounsfield units (HU) in men and 98.8 (34.1) HU in women. Ninety-one patients (15%) met the criteria for osteosarcopenia and had higher rates of frailty, fractures, and malnutrition at baseline. One-year mortality was highest in patients with osteosarcopenia (29 patients [32%]) followed by those with low PMA alone (18 patients [14%]), low VBD alone (16 patients [11%]), and normal bone and muscle status (21 patients [9%]) (P < .001). Osteosarcopenia, but not low VBD or PMA alone, was independently associated with 1-year mortality (odds ratio [OR], 3.18; 95% CI, 1.54-6.57) and 1-year worsening disability (OR, 2.11; 95% CI, 1.19-3.74). The association persisted in sensitivity analyses adjusting for the Essential Frailty Toolset, Clinical Frailty Scale, and geriatric conditions such as malnutrition and disability. Conclusions and Relevance: The findings suggest that osteosarcopenia detected using clinical CT scans could be used to identify frail patients with a 3-fold increase in 1-year mortality following TAVR. This opportunistic method for osteosarcopenia assessment could be used to improve risk prediction, support decision-making, and trigger rehabilitation interventions in older adults.

Background: This study sought to compare characteristics and outcomes of patients who underwent surgical aortic valve replacement (SAVR) after being referred to a heart team (HT), to those of patients referred directly for SAVR. Methods: An analysis of patients who underwent SAVR from 2015 to 2020 was conducted. Patients were categorized into 3 groups, as follows: (i) H-HT: patients referred to the HT from 2015 to 2017 (historical cohort); (ii) C-HT: patients referred to the HT from 2018 to 2020 (contemporary cohort); and (iii) No-HT: patients referred directly to cardiac surgery from 2018 to 2020. Two subanalyses were performed: H-HT vs C-HT patients, and C-HT vs No-HT patients. The primary outcome was a composite of in-hospital mortality, prolonged intubation, reoperation, sternal wound infection, and stroke. Results: This study consisted of 288 patients, distributed as follows: H-HT (n = 45); C-HT (n = 51); and No-HT (n = 192). The mean ages of H-HT, C-HT, and No-HT patients was 76.3 ± 6.9 years, 73.3 ± 7.6 years, and 69.6 ± 9.7 years, respectively (P = 0.0001). H-HT, C-HT, and No-HT patients had average Society of Thoracic Surgeons scores of 4.8 ± 2.2, 3.2 ± 1.6, and 4.2 ± 2 (P = 0.002), respectively. The composite outcome rate was more than 5 times higher among H-HT patients compared to that among the C-HT patients (20.0 vs 3.9%, P = 0.02), and was numerically higher in No-HT compared to C-HT patients (13.0 vs 3.9%, P = 0.07). Conclusions: Referral to an HT appears to be primarily driven by higher chronological age rather than overall risk profile. Patients assessed by the HT prior to undergoing SAVR have a low incidence of complications, comparable to that among patients referred directly to cardiac surgery.
Contexte: Cette étude visait à comparer les caractéristiques et le devenir de patients ayant subi une chirurgie de remplacement valvulaire aortique après avoir été orientés vers une équipe de cardiologie (EC) à ceux de patients orientés directement en chirurgie cardiaque pour une chirurgie de remplacement valvulaire aortique. Méthodologie: Une analyse portant sur les patients ayant subi une chirurgie de remplacement valvulaire aortique de 2015 à 2020 a été effectuée. Les patients ont été divisés en trois groupes, à savoir : i) CH-POEC : patients orientés vers une EC de 2015 à 2017 (cohorte historique); ii) CC-POEC : patients orientés vers une EC de 2018 à 2020 (cohorte contemporaine); iii) PODC : patients orientés directement en chirurgie cardiaque de 2018 à 2020. Deux sous-analyses ont été effectuées : CH-POEC vs CC-POEC, et CC-POEC vs PODC. Le paramètre d'évaluation principal était composite. Il comprenait la mortalité hospitalière, l'intubation prolongée, la réopération, l'infection de la plaie sternale et l'accident vasculaire cérébral. Résultats: L'étude regroupait 288 patients, répartis comme suit : CH-POEC, n = 45; CC-POEC, n = 51; PODC, n = 192. L'âge moyen dans les groupes CH-POEC, CC-POEC et PODC était respectivement de 76,3 ± 6,9 ans, 73,3 ± 7,6 ans et 69,6 ± 9,7 ans (P = 0,0001). Les groupes CH-POEC, CC-POEC et PODC présentaient des indices STS (Society of Thoracic Surgeons) moyens de 4,8 ± 2,2, 3,2 ± 1,6 et 4,2 ± 2 (P = 0,002), respectivement. Le taux composite d'événements au sein du groupe CH-POEC était plus de cinq fois supérieur à celui noté dans le groupe CC-POEC (20,0 vs 3,9 %, P = 0,02). Il était aussi plus élevé au sein du groupe PODC comparativement au groupe CC-POEC (13,0 vs 3,9 %, P = 0,07). Conclusions: Le principal motif d'orientation vers une EC semble être un âge chronologique avancé plutôt que le profil de risque global. Chez les patients qui sont évalués par une EC avant de subir une chirurgie de remplacement valvulaire aortique, l'incidence de complications est faible et comparable à celle observée chez les patients orientés directement en chirurgie cardiaque.
RESUMEN
BACKGROUND: Although multidimensional frailty scales have been proven to predict mortality and morbidity in cardiac surgery, there is a need for rapid tools that could be easily administered at the point of care. Handgrip strength (HGS) is an attractive option that can be measured in acutely ill and bed-bound patients, although it has yet to be validated in a large cardiac surgery cohort. METHODS: This is a post hoc analysis of a multicentre prospective study in older patients undergoing coronary artery bypass grafting and/or valve surgery from 2011 to 2019. HGS was measured before surgery and classified by sex-stratified cutoffs. The primary outcome was 1-year mortality and secondary outcomes were 30-day mortality, discharge disposition, and prolonged length of stay. RESULTS: There were 1245 patients included in the analysis (mean age 74.0 ± 6.6 years; 30% female). Weak HGS was associated with advanced age, heart failure, kidney disease, malnutrition, and various frailty scales. In those with weak vs normal HGS, respectively, 1-year mortality was 17% vs 6%, 30-day mortality was 10% vs 3%, prolonged length of stay was 34% vs 19%, and discharge to a health care facility was 45% vs 26% (all P < 0.001). After adjustment, HGS was predictive of 1-year and 30-day mortalities, with odds ratios of 2.44 (95% confidence interval [CI] 1.39-4.29) and 2.83 (1.38-5.81), respectively. HGS cutoffs of < 26 kg in men and < 16 kg in women had the highest predictive performance. CONCLUSIONS: HGS is a simple and effective tool to identify patients at higher risk of mortality and protracted recovery after cardiac surgery.
