Does Comprehensive Geriatric Assessment Reduce the Incidence of Postoperative Delirium? A Quasi-experimental Study in Older Adults Undergoing Transcatheter Aortic Valve Implantation. Clin Interv Aging 2024; 19:347-355. [PMID: 38434577 PMCID: PMC10909326 DOI: 10.2147/cia.s448167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Accepted: 02/06/2024] [Indexed: 03/05/2024] Open
Abstract
Purpose Postoperative delirium (POD) after transcatheter aortic valve implantation (TAVI) is frequent in older adults and associated with multiple negative outcomes including a higher mortality. We aimed to investigate whether a comprehensive geriatric assessment (CGA) prior to TAVI reduces the odds of POD and results in a positive change in self-care ability, intended to lay a foundation for future geriatric comanagement. Patients and methods We used a retrospective, single-center study with a quasi-experimental design enrolling patients aged 70 years and older undergoing CGA before elective TAVI, and a nonrandomized comparison group without preoperative CGA. Data on POD occurrence during the first 5 days after TAVI (primary outcome) and change in self-care ability index (SPI) between admission and discharge (secondary outcome) were collected from electronic health records and CGA data (exposure) by clinical assessment. To explore associations between (1) CGA and POD, and (2) CGA and SPI, multivariate logistic regression and linear regression models were applied adjusting for age, sex, BMI, and number of medications. Results Among 435 patients (mean age 81.0 ± 5.6 years, 43.6% women, median [IQR] SPI at baseline 40 [39, 40] points), POD incidence was 14.3% in the CGA group vs 18.8% in the non-CGA group (P 0.219). Undergoing CGA before TAVI was not associated with the odds for POD (OR: 1.15; 95%CI: 0.65-2.04) or improved SPI (P 0.073). Conclusion We observed no association of CGA prior to TAVI with POD incidence or postoperative self-care, highlighting the need for additional studies investigating the effect of POD preventive measures in older TAVI patients integrated into a comprehensive geriatric comanagement program.

Roles and competencies of nurses and physicians in shared decision-making in cardiac surgery: A scoping review. J Adv Nurs 2024; 80:60-72. [PMID: 37525406 DOI: 10.1111/jan.15811] [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: 02/08/2023] [Revised: 06/30/2023] [Accepted: 07/20/2023] [Indexed: 08/02/2023]
Abstract
AIM Identification and synthesis of research data related to the roles and competencies of physicians and nurses that are prerequisites for careful shared decision-making with patients potentially undergoing cardiac surgery. DESIGN A scoping review was conducted in accordance with the Joanna Briggs Institute's methodology for scoping reviews and the PRISMA Extension for Scoping Reviews. METHODS PubMed, EMBASE and CINAHL were searched from inception dates up to March 2022, to identify primary studies published in a peer-reviewed journal. Study selection, assessment of the methodological quality and data extracting of the included studies were done by at least two independent researchers. To describe the findings of the studies, an emergent synthesis approach was used to visualize a descriptive representation of professional roles and competencies in shared decision-making, in an overview. RESULTS The systematic search revealed 10,055 potential papers, 8873 articles were screened on title and abstract and 76 full texts were retrieved. Eight articles were included for final evaluation. For nurses and physicians, 26 different skills were identified in the literature to practice shared decision-making in cardiac surgery. The skills that emerged were divided into five professional roles: moderator; health educator; data collector; psychological supporter and translator. CONCLUSIONS This review specifies the professional roles and required competencies related to shared decision-making in cardiac surgery. Further research is needed to compare our findings with other clinical areas and from there to arrive at a professional division of roles between the different clinical disciplines involved. IMPACT The visualization of generic shared decision-making competencies and roles should establish the professional division of positions between various clinical physician and nurse disciplines in order to create a treatment plan based on evidence, values, preferences and the patient's personal situation.

Prevalence and correlates of frailty in older hypertensive outpatients according to different tools: the HYPER-FRAIL pilot study. J Hypertens 2024; 42:86-94. [PMID: 37698894 PMCID: PMC10713004 DOI: 10.1097/hjh.0000000000003559] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 07/15/2023] [Accepted: 08/23/2023] [Indexed: 09/13/2023]
Abstract
OBJECTIVES To date, few studies have investigated frailty in hypertensive individuals. This study aimed at identifying the prevalence of frailty in a sample of hypertensive older outpatients using six different identification tools. Clinical correlates of frailty and agreement between different frailty definitions were also investigated. METHODS The HYPER-FRAIL pilot study recruited hypertensive patients aged at least 75 years from two geriatric outpatient clinics of Careggi Hospital, Florence, Italy. Four frailty scales [Fried Frailty Phenotype, Frailty Index, Clinical Frailty Scale (CFS), Frailty Postal Score] and two physical performance tests [Short Physical Performance Battery (SPPB) and usual gait speed] were applied. The Cohen's kappa coefficient was calculated to assess agreement between measures. Multiple logistic regression was used to identify clinical features independently associated with frailty. RESULTS Among 121 participants (mean age 81, 60% women), frailty prevalence varied between 33 and 50% according to the tool used. Moderate agreement was observed between Fried Frailty Phenotype, Frailty Index and SPPB, and between Frailty Index and CFS. Agreement was minimal or weak between the remaining measures (K < 0.60). Use of walking aids and depressive symptoms were independently associated with frailty, regardless of the definition used. Frailty correlates also included dementia, disability and comorbidity burden, but not office and 24-h blood pressure values. CONCLUSION Frailty is highly prevalent among older hypertensive outpatients, but agreement between different frailty tools was moderate-to-weak. Longitudinal studies are needed to assess the prognostic role of different frailty tools and their clinical utility in the choice of antihypertensive treatment.

Abstract
OBJECTIVES To investigate the effect of moderate-intensity continuous training (MICT) on the improvement of cardiopulmonary function for patients undergoing transcatheter aortic valve replacement (TAVR). DESIGN Randomized controlled study. SETTING AND PARTICIPANTS Between August 20, 2021, and February 28, 2022, a total of 66 patients after TAVR were screened for inclusion and randomly divided into the MICT and control groups at a ratio of 1:1. MICT was scheduled 3 times per week for 3 months in the intervention group. Patients in the control group received one-time advice on physical activity according to the current guideline. METHODS The primary endpoint was the 3-month change in peak oxygen consumption (peak VO2) assessed by cardiopulmonary exercise testing. The secondary endpoints included the 3-month change in 6-minute walk test (6MWT), the 12-Item Short Form Health Survey (SF-12), New York Heart Association (NYHA) class, echocardiographic parameters, and laboratory parameters. RESULTS After 3 months, the change in peak VO2 was higher in the MICT group than that in the control group (1.63 mL/kg/min, 95% CI 0.58-2.67, P = .003). Change in 6MWT (21.55 m, 95% CI 0.38-42.71, P = .046) was higher in the MICT group compared with the control group. A significant change in favor of MICT was also observed for low-density lipoprotein cholesterol (-0.62 mmol/L, 95% CI -1.00 to -0.23, P = .002). However, there were no significant changes in other echocardiographic indices, laboratory parameters, and SF-12 between the 2 groups (all P > .05). CONCLUSIONS AND IMPLICATIONS MICT had a positive effect on the cardiopulmonary function and physical capacity of patients after TAVR.

Eyeball Test for the Assessment of Frailty in Elderly Patients With Cardiovascular Disease: A Prospective Study. Am J Cardiol 2023; 204:9-13. [PMID: 37536207 DOI: 10.1016/j.amjcard.2023.07.039] [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: 02/19/2023] [Revised: 07/03/2023] [Accepted: 07/08/2023] [Indexed: 08/05/2023]
Abstract
Frailty has been associated with poor outcomes in patients with cardiovascular diseases (CVDs). We aimed to assess the accuracy of the Eyeball test for frailty assessment in elderly patients with CVD. This is a prospective study including stable patients ≥75 years old who were followed-up in a cardiology clinic. Frailty assessment was performed separately through the Eyeball test and the Fried test in a blinded way. Cardiologists were asked to rate the frailty status of participants based on their routine clinical assessment and grade frailty on a Fried-type scale (1 to 5, with frailty defined as a score ≥3). Each patient then underwent formal frailty assessment using the Fried test. Included were 300 consecutive patients with a mean age of 81 ± 6 years. Frailty was diagnosed in 109 (36%) and 125 patients (41%) according to the Fried and Eyeball tests, respectively. The Eyeball test demonstrated 86% sensitivity and 82% specificity for the diagnosis of frailty. A receiver operating characteristics curve analysis demonstrated an area under the curve of 0.82 for the diagnosis of frailty. The Eyeball test demonstrated a very high negative predictive value of 90% and a modest positive predictive value of 73% for frailty assessment. Similar results were observed after subgroup analysis according to age and gender. In conclusion, the Eyeball test is an accurate method to rule out frailty in elderly patients with CVD. However, when frailty is suspected based on the Eyeball test, a formal tool such as the Fried test should be used to confirm the diagnosis.

Abstract
BACKGROUND The recommendation for transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) in patients 65 to 80 years of age is equivocal, leaving patients with a difficult decision. We evaluated whether TAVR compared to SAVR is associated with reduced odds for loss of independent living in patients ≤65, 66 to 79, and ≥80 years of age. Further, we explored mechanisms of the association of TAVR and adverse discharge. METHODS Adult patients undergoing TAVR or SAVR within a large academic medical system who lived independently before the procedure were included. A multivariable logistic regression model, adjusting for a priori defined confounders including patient demographics, preoperative comorbidities, and a risk score for adverse discharge after cardiac surgery, was used to assess the primary association. We tested the interaction of patient age with the association between aortic valve replacement (AVR) procedure and loss of independent living. We further assessed whether the primary association was mediated (ie, percentage of the association that can be attributed to the mediator) by the procedural duration as prespecified mediator. RESULTS A total of 1751 patients (age median [quartiles; min-max], 76 [67, 84; 23-100]; sex, 56% female) were included. A total of 27% (222/812) of these patients undergoing SAVR and 20% (188/939) undergoing TAVR lost the ability to live independently. In our cohort, TAVR was associated with reduced odds for loss of independent living compared to SAVR (adjusted odds ratio [OR adj ] 0.19 [95% confidence interval {CI}, 0.14-0.26]; P < .001). This association was attenuated in patients ≤65 years of age (OR adj 0.63 [0.26-1.56]; P = .32) and between 66 and 79 years of age (OR adj 0.23 [0.15-0.35]; P < .001), and magnified in patients ≥80 years of age (OR adj 0.16 [0.10-0.25]; P < .001; P -for-interaction = .004). Among those >65 years of age, a shorter procedural duration mediated 50% (95% CI, 28-76; P < .001) of the beneficial association of TAVR and independent living. CONCLUSIONS Patients >65 years of age undergoing TAVR compared to SAVR had reduced odds for loss of independent living. This association was partly mediated by shorter procedural duration. No association between AVR approach and the primary end point was found in patients ≤65 years of age.

Depression and Malnutrition for Prediction of Mortality after Transcatheter Aortic Valve Replacement: A Registry Study of a Tertiary Referral Hospital. Diagnostics (Basel) 2023; 13:2561. [PMID: 37568924 PMCID: PMC10416912 DOI: 10.3390/diagnostics13152561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 07/28/2023] [Accepted: 07/31/2023] [Indexed: 08/13/2023] Open
Abstract
Moderate to severe frailty is a predictor of a poor outcome after transcatheter aortic valve replacement (TAVR), but little is known about the prognostic importance of different geriatric frailty markers in an overall fit or pre-frail geriatric population undergoing TAVR. This retrospective study aimed to examine the incremental value of adding patient frailty markers to conventional surgical risk score to predict all-cause mortality in relatively fit elderly patients undergoing TAVR. Overall patient frailty was assessed using the comprehensive geriatric assessment frailty index (CGA-FI). Multivariable Cox regression models were used to evaluate relationships of different geriatric frailty markers with all-cause mortality and single and combined frailty models were compared to a baseline model that included EuroSCORE II factors. One hundred relatively fit geriatric patients (84 ± 4 years old, mean CGA-FI 0.14 ± 0.05) were included, and 28% died during a median follow-up of 24 months. After adjustment, risk of depression (geriatric depression scale 15 (GDS-15)) and malnutrition remained significantly associated with all-cause mortality (HR 4.381, 95% CI 1.787-10.743; p = 0.001 and HR 3.076, 95% CI 1.151-8.217; p = 0.025, respectively). A combined frailty marker model including both GDS-15 and malnutrition on top of EuroSCORE II improved the discriminative ability to predict all-cause mortality (change in c-index: + 0.044). Screening for those frailty markers on top of the traditionally used EuroSCORE II may improve risk stratification and prognosis in relatively fit geriatric patients undergoing TAVR.

Clinical Frailty Scale as a predictor of adverse outcomes following aortic valve replacement: a systematic review and meta-analysis. Open Heart 2023; 10:e002354. [PMID: 37567604 PMCID: PMC10423827 DOI: 10.1136/openhrt-2023-002354] [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: 04/24/2023] [Accepted: 07/03/2023] [Indexed: 08/13/2023] Open
Abstract
OBJECTIVES Assessment of frailty prior to aortic valve intervention is recommended in European and North American valvular heart disease guidelines. However, there is a lack of consensus on how it is best measured. The Clinical Frailty Scale (CFS) is a well-validated measure of frailty that is relatively quick to calculate. This meta-analysis sought to examine whether the CFS predicts mortality and morbidity following either transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR). METHODS Nine electronic databases were searched systematically for data on clinical outcomes post-TAVI/SAVR, where patients had undergone preoperative frailty assessment using the CFS. The primary endpoint was 12-month mortality. TAVI and SAVR data were assessed and reported separately. For each individual study, the incidence of adverse outcomes was extracted according to a CFS score of 5-9 (ie, frail) versus 1-4 (ie, non-frail), with meta-analysis performed using a random effects model. RESULTS Of 2612 records screened, nine were included in the review (five TAVI, three SAVR and one which included both interventions). Among 4923 TAVI patients, meta-analysis showed 12-month mortality rates of 19.1% for the frail cohort versus 9.8% for the non-frail cohort (RR 2.53 (1.63 to 3.95), p<0.001, I2=83%). For the smaller cohort of SAVR patients (n=454), mortality rates were 20.3% versus 3.9% for the frail and non-frail cohorts, respectively (RR 5.08 (2.31 to 11.15), p<0.001, I2=5%). CONCLUSIONS Frailty, as determined by the CFS, was associated with an increased mortality risk in the 12 months following either TAVI or SAVR. These data would support its use in the preoperative assessment of elderly patients undergoing aortic valve interventions.

The prognostic impacts of frailty on clinical and patient-reported outcomes in patients undergoing coronary artery or valvular surgeries/procedures: A systematic review and meta-analysis. Ageing Res Rev 2023; 85:101850.

Abstract
BACKGROUND Frailty is emerging as an important prognostic indicator for patients undergoing cardiac surgeries/procedures. We sought to evaluate the prognostic and differential impacts of frailty on patients undergoing coronary artery or valvular surgical procedures of different levels of invasiveness, and to explore the differential predictability of various frailty measurement models. METHODS Eight databases were searched for prospective cohort studies that have adopted validated measure(s) of frailty and reported clinical, healthcare service utilization, or patient-reported outcomes in patients undergoing coronary artery or valvular surgeries/procedures. RESULTS Sixty-two articles were included (N = 16,679). Frailty significantly predicted mortality (short-term [≤ 30 days]: odds ratio [OR]: 2.33, 95% confidence interval [CI]: 1.28-4.26; midterm [6 months to 1 year]: OR: 3.93, 95%CI: 2.65-5.83; long-term [>1 year]: HR: 2.23, 95%CI: 1.60-3.11), postoperative complications (ORs: 2.54-3.57), discharge to care facilities (OR: 5.52, 95%CI: 3.84-7.94), hospital readmission (OR: 2.00, 95%CI: 1.15-3.50), and reduced health-related quality of life (HRQoL; standardized mean difference: -0.74, 95%CI: -1.30 to -0.18). Subgroup analyses showed that frailty exerted a greater impact on short-term mortality in patients undergoing open-heart surgeries than those receiving transcatheter procedures. Multidimensional and physical-aspect-focused frailty measurements performed equally in predicting mortality, but multidimensional measurements were more predictive of hospital readmission than physical-aspect-focused measurements. CONCLUSION Frailty was predictive of postoperative mortality, complications, increased healthcare service utilization, and reduced HRQoL. The impact of frailty on short-term mortality was more prominent in patients undergoing open-heart surgeries than those receiving transcatheter procedures. Multidimensional measures of frailty enhanced prognostic risk estimation, especially for hospital readmission.

Abstract
AIMS Usage of transcatheter aortic valve implantation (TAVI) for treatment of severe aortic stenosis is increasing across age groups. However, literature on age-specific TAVI outcomes is lacking. The purpose of this study is to assess the risks of procedural complications, mortality, and readmission in patients undergoing TAVI across different age groups. METHODS AND RESULTS The Nationwide Readmissions Database was used to identify 84 017 patients undergoing TAVI from 2016 to 2018. Patients were stratified into four age groups: younger than 70, 70-79, 80-89, and older than 90. Complications, mortality, and readmission rates were compared between groups in a proportional hazards regression model. Risk of post-procedural stroke, acute kidney injury, and pacemaker or implantable cardioverter defibrillator implantation increased with incremental age grouping. Compared with patients younger than 70, patients aged 70-79 had no significant difference in mortality, whereas patients aged 80-89 and older than 90 had an increased mortality risk [odds ratio (OR) 1.39, confidence interval (CI) 1.14-1.70, P = 0.001 and OR 1.68, CI 1.33-2.12, P < 0.001, respectively]. Patients aged 80-89 and older than 90 had increased overall readmission compared with patients younger than 70 (HR 1.09, CI 1.03-1.14, P = 0.001 and HR 1.33, CI 1.25-1.41, P < 0.001, respectively). Cardiac readmissions followed the same trend. CONCLUSION Patients aged 80-89 and older than 90 undergoing TAVI have increased risk of readmission, complications, and mortality compared with patients younger than 70.

Abstract
BACKGROUND A significant number of older patients planned for transcatheter aortic valve implantation (TAVI) experience a decline in physical functioning and death, despite a successful procedure. OBJECTIVE To systematically review the literature on the association of preprocedural muscle strength and physical performance with functional decline or long-term mortality after TAVI. METHODS We followed the PRISMA guidelines and pre-registered this review at PROSPERO (CRD42020208032). A systematic search was conducted in MEDLINE and EMBASE from inception to 10 December 2021. Studies reporting on the association of preprocedural muscle strength or physical performance with functional decline or long-term (>6 months) mortality after the TAVI procedure were included. For outcomes reported by three or more studies, a meta-analysis was performed. RESULTS In total, two studies reporting on functional decline and 29 studies reporting on mortality were included. The association with functional decline was inconclusive. For mortality, meta-analysis showed that low handgrip strength (hazard ratio (HR) 1.80 [95% confidence interval (CI): 1.22-2.63]), lower distance on the 6-minute walk test (HR 1.15 [95% CI: 1.09-1.21] per 50 m decrease), low performance on the timed up and go test (>20 s) (HR 2.77 [95% CI: 1.79-4.30]) and slow gait speed (<0.83 m/s) (HR 2.24 [95% CI: 1.32-3.81]) were associated with higher long-term mortality. CONCLUSIONS Low muscle strength and physical performance are associated with higher mortality after TAVI, while the association with functional decline stays inconclusive. Future research should focus on interventions to increase muscle strength and physical performance in older cardiac patients.

Abstract
The incidence of aortic stenosis (AS) increases with age and is a serious problem in an aging society. In recent years, transcatheter aortic valve implantation (TAVI) has been performed widely; however, older patients may be ineligible for TAVI or surgical treatment because of medical ineligibility. Symptom-based rehabilitation is required for these patients to maintain and improve their physical function and ability to perform activities of daily living. No studies have examined exercise safety for older patients with severe AS who are ineligible for TAVI or surgery. We summarized the safety of exercise for older patients with severe AS, collecting 7 studies on maximal exercise stress tests and 16 studies on preoperative physical examinations. From this review, it may be unlikely that exercise under appropriate management can cause hemodynamic changes, leading to death. However, there were no studies on exercise intervention for older patients with AS who are chosen for conservative management. The optimal exercise intensity for symptomatic older patients with AS undergoing conservative management and the effects of continuous exercise intervention require future study.

Frailty Test Battery Development including Physical, Socio-Psychological and Cognitive Domains for Cardiovascular Disease Patients: A Preliminary Study. J Clin Med 2022; 11:jcm11071926. [PMID: 35407534 PMCID: PMC9014815 DOI: 10.3390/jcm11071926] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 03/25/2022] [Accepted: 03/28/2022] [Indexed: 01/23/2023] Open
Abstract
Frailty is an age-related decline in physical, socio-psychological and cognitive function that results in extreme vulnerability to stressors. Therefore, this study aimed to elucidate which tests have to be selected to detect frailty in a comprehensive and feasible manner in cardiovascular disease (CVD) patients based on multivariate regression and sensitivity/specificity analyses. Patients (n = 133, mean age 78 ± 7 years) hospitalised for coronary revascularisation or heart failure (HF) were examined using the Fried and Vigorito criteria, together with some additional measurements. Moreover, to examine the association of frailty with 6-month clinical outcomes, hospitalisations and mortality up to 6 months after the initial hospital admission were examined. Some level of frailty was detected in 44% of the patients according to the Vigorito criteria and in 65% of the patients according to the Fried criteria. Frailty could best be detected by a score based on: sex, Mini Nutritional Assessment (MNA), Katz scale, timed up-and-go test (TUG), handgrip strength, Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS-15) and total number of medications. Frailty and specific markers of frailty were significantly associated with mortality and six-month hospitalisations. We thus can conclude that, in patients with CVD, sex, MNA, Katz scale, TUG, handgrip strength, MMSE, GDS-15 and total number of medications play a key role in detecting frailty, assessed by a new time- and cost-efficient test battery.

Abstract
Background Perioperative neurocognitive disorder includes postoperative cognitive dysfunction (POCD) and postoperative delirium (POD). Concerning inconclusive consequences of POCD compared with POD, we explored the association between either POCD or POD and functional decline as well as healthcare utilization. Methods Patients aged at least 60 years who underwent a major operation were enrolled. POCD was defined as a decrease in the Montreal Cognitive Assessment (MoCA) score (≥ 2) 1 week after surgery. Postoperative delirium (POD) was defined according to the criteria of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The primary outcome was instrumental activities of daily living (IADLs) 3 months after discharge. Secondary outcomes were the length of stay (LOS), hospital cost, and factors that affected functional decline 3 months after surgery. The multivariate model, including potential confounding factors, namely age, gender, surgery type, and postoperative complications, was used to analyze possible factors that influenced a reduction in function, and the results were expressed by using adjusted relative risk (RR) and 95%CI. Results Two hundred eighty-nine patients with a mean age of 72 years were enrolled. The incidence of POCD at 1 week was 28.5%. At their 3-month follow-ups, the patients with POCD were not associated with IADL decline. Nevertheless, patients with POCD were more likely to need a prolonged LOS (11 days [1, 46] vs. 8 days [2, 42]; P = 0.01), and incur higher hospital costs (8973.43 USD [3481.69, 11 763.74] vs. 5913.62 USD [332.43, 19 567.33]; P < 0.001). Additionally, the patients experiencing POD demonstrated increased risks of reducing their IADLs (adjusted RR 2.33; 95% CI, 1.15–4.71; P = 0.02). Conclusions POCD at 1 week leaded to increase healthcare utilization in a middle-income country. POD during hospitalization was associated with a decline in function after surgery and increased health care utilization. Trial registration Thai Clinical Trials Registry TCTR20190115001.

Influence of preoperative frailty on quality of life after cardiac surgery: Protocol for a systematic review and meta-analysis. PLoS One 2022; 17:e0262742. [PMID: 35120151 PMCID: PMC8815968 DOI: 10.1371/journal.pone.0262742] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Accepted: 01/04/2022] [Indexed: 11/19/2022] Open
Abstract
Background
Frailty has emerged as an important prognostic marker of adverse outcomes after cardiac surgery, but evidence regarding its ability to predict quality of life after cardiac surgery is currently lacking. Whether frail patients derive the same quality of life benefit after cardiac surgery as patients without frailty remains unclear.
Methods
This systematic review will include interventional studies (RCT and others) and observational studies evaluating the effect of preoperative frailty on quality-of-life outcomes after cardiac surgery amongst patients 65 years and older. Studies will be retrieved from major databases including the Cochrane Central Register of Controlled Trials, Embase, and Medline. The primary exposure will be frailty status, independent of the tool used. The primary outcome will be change in quality of life, independent of the tool used. Secondary outcomes will include readmission during the year following the index intervention, discharge to a long-term care facility and living in a long-term care facility at one year. Screening, inclusion, data extraction and quality assessment will be performed independently by two reviewers. Meta-analysis based on the random-effects model will be conducted to compare the outcomes between frail and non-frail patients. The evidential quality of the findings will be assessed with the GRADE profiler.
Conclusion
The findings of this systematic review will be important to clinicians, patients and health policy-makers regarding the use of preoperative frailty as a screening and assessment tool before cardiac surgery.

The need for long-term personalized management of frail CVD patients by rehabilitation and telemonitoring: a framework. Trends Cardiovasc Med 2022:S1050-1738(22)00023-8.

Abstract
Due to advances in cardiovascular medicine and preventive cardiology, patients benefit from a better prognosis, even in case of significant disease burden such as acute and chronic coronary syndromes, advanced valvular heart disease and chronic heart failure. These advances have allowed CVD patients to increase their life expectancy, but on the other hand also experience aging-related syndromes such as frailty. Despite being underrecognized, frailty is a critical, common, and co-existent condition among older CVD patients, leading to exercise intolerance and compromised adherence to cardiovascular rehabilitation. Moreover, frail patients need a different approach for CR and are at very high risk for adverse events, but yet are underrepresented in conventional CR. Fortunately, recent advances have been made in technology, allowing remote monitoring, coaching and supervision of CVD patients in secondary prevention programs with promising benefits. Similarly, we hypothesized that such programs should also be implemented to treat frailty in CVD patients. However, considering frail patients' particular needs and challenges, telerehabilitation interventions should thus be appropriately adapted. Our purpose is to provide, for the first time and based on expert opinions, a framework of how such a cardiac telerehabilitation program could be developed and implemented to manage a prevention and rehabilitation program for CVD patients with frailty.

Futility in Transcatheter Aortic Valve Implantation: A Search for Clarity. Interv Cardiol 2022; 17:e01.

Abstract
Although transcatheter aortic valve implantation (TAVI) has revolutionised the landscape of treatment for aortic stenosis, there exists a cohort of patients where TAVI is deemed futile. Among the pivotal high-risk trials, one-third to half of patients either died or received no symptomatic benefit from the procedure at 1 year. Futility of TAVI results in the unnecessary exposure of risk for patients and inefficient resource utilisation for healthcare services. Several cardiac and extra-cardiac conditions and frailty increase the risk of mortality despite TAVI. Among the survivors, these comorbidities can inhibit improvements in symptoms and quality of life. However, certain conditions are reversible with TAVI (e.g. functional mitral regurgitation), attenuating the risk and improving outcomes. Quantification of disease severity, identification of reversible factors and a systematic evaluation of frailty can substantially improve risk stratification and outcomes. This review examines the contribution of pre-existing comorbidities towards futility in TAVI and suggests a systematic approach to guide patient evaluation.

Abstract
OBJECTIVES In this study, we use a national database to evaluate post-transcatheter (TAVR)/surgical aortic valve replacement (SAVR) outcomes stratified using chronic liver disease (CLD). BACKGROUND In patients undergoing TAVR and SAVR, the surgical risks should be optimized; this includes evaluating hepatic diseases that may pose an operative risk. METHODS 2011-2017 National Inpatient Sample was used to select in-hospital TAVR and SAVR cases, which were stratified according to CLD (cirrhosis, hepatitis B/C, alcoholic/fatty/nonspecific liver disease). The cases-controls were matched using propensity score matching and compared with various endpoints. RESULT After matching for demographics and comorbidities, for TAVR, 606 and 1818 were with or without CLD; for SAVR, 1353 and 4059 were with and without CLD. In TAVR, there was no differences in mortality (2.81% vs. 2.75% OR 1.02 95% CI 0.58-1.78) or length of stay (6.29 vs. 6.44d p = 0.29), and CLD-present patients had marginally increased costs ($228,415 vs. $226,682 p = 0.048). There were no differences in complications. In multivariate, there was no difference in mortality (aOR 1.02 95% CI 0.58-1.79). In SAVR, CLD patients had higher mortality (7.98% vs. 3.23% OR 2.60 95% CI 2.00-3.38), length of stay (13.3 vs. 11.3 days p < 0.001), and costs ($273,487 vs. $238,097 p < 0.001). CLD patients also had increased respiratory failure (9.02% vs. 7.19% OR 1.28 95% CI 1.03-1.59) and bleeding (8.43% vs. 6.33% OR 1.36 95% CI 1.08-1.71). In multivariate, CLD had higher mortality (aOR 2.60 95% CI 2.00-3.38). CONCLUSION CLD is associated with higher mortality and complications in patients undergoing SAVR; however, no correlation was found in patients undergoing TAVR.

Abstract
Background: Frailty is associated with a higher risk for adverse outcomes after aortic valve replacement (AVR) for severe aortic valve stenosis, but whether or not frail patients derive differential benefit from transcatheter (TAVR) vs. surgical (SAVR) AVR is uncertain. Methods: We linked adults ≥ 65 years old in the US CoreValve High Risk (HiR) or Surgical or Transcatheter Aortic-Valve Replacement in Intermediate Risk Patients (SURTAVI) trial to Medicare claims, 2/2/2011-9/30/2015. Two frailty measures, a deficit-based (DFI) and phenotype-based (PFI) frailty index, were generated. The treatment effect of TAVR vs. SAVR was evaluated within frailty index (FI) tertiles for the primary endpoint of death and non-death secondary outcomes, using multivariable Cox regression. Results: Of 1,442 (linkage rate = 60.0%) individuals included, 741 (51.4%) individuals received TAVR and 701 (48.6%) received SAVR (mean age 81.8 ± 6.1 years, 44.0% female). Though 1-year death rates in the highest FI tertiles (DFI 36.7%, PFI 33.8%) were 2-3-fold higher than the lowest tertiles (DFI 13.4%, HR 3.02, 95% CI 2.26-4.02, p < 0.001; PFI 17.9%; HR 2.05, 95% CI 1.58-2.67, p < 0.001), there were no significant differences in the relative or absolute treatment effect of SAVR vs. TAVR across FI tertiles for all death, non-death, and functional outcomes (all interaction p-values > 0.05). Results remained consistent across individual trials, frailty definitions, and when considering the non-linked trial data. Conclusions: Two different frailty indices based on Fried and Rockwood definitions identified individuals at higher risk of death and functional impairment but no differential benefit from TAVR vs. SAVR.

Abstract
Background In aortic valve disease, the relationship between claims‐based frailty indices (CFIs) and validated measures of frailty constructed from in‐person assessments is unclear but may be relevant for retrospective ascertainment of frailty status when otherwise unmeasured. Methods and Results We linked adults aged ≥65 years in the US CoreValve Studies (linkage rate, 67%; mean age, 82.7±6.2 years, 43.1% women), to Medicare inpatient claims, 2011 to 2015. The Johns Hopkins CFI, validated on the basis of the Fried index, was generated for each study participant, and the association between CFI tertile and trial outcomes was evaluated as part of the EXTEND‐FRAILTY substudy. Among 2357 participants (64.9% frail), higher CFI tertile was associated with greater impairments in nutrition, disability, cognition, and self‐rated health. The primary outcome of all‐cause mortality at 1 year occurred in 19.3%, 23.1%, and 31.3% of those in tertiles 1 to 3, respectively (tertile 2 versus 1: hazard ratio, 1.22; 95% CI, 0.98–1.51; P=0.07; tertile 3 versus 1: hazard ratio, 1.73; 95% CI, 1.41–2.12; P<0.001). Secondary outcomes (bleeding, major adverse cardiovascular and cerebrovascular events, and hospitalization) were more frequent with increasing CFI tertile and persisted despite adjustment for age, sex, New York Heart Association class, and Society of Thoracic Surgeons risk score. Conclusions In linked Medicare and CoreValve study data, a CFI based on the Fried index consistently identified individuals with worse impairments in frailty, disability, cognitive dysfunction, and nutrition and a higher risk of death, hospitalization, bleeding, and major adverse cardiovascular and cerebrovascular events, independent of age and risk category. While not a surrogate for validated metrics of frailty using in‐person assessments, use of this CFI to ascertain frailty status among patients with aortic valve disease may be valid and prognostically relevant information when otherwise not measured.

Abstract
Frailty assessment is recommended before elective transcatheter aortic valve implantation (TAVI) to determine post-interventional prognosis. Several studies have investigated frailty in TAVI-patients using numerous assessments; however, it remains unclear which is the most appropriate tool for clinical practice. Therefore, we evaluate which frailty assessment is mainly used and meaningful for ≤30-day and ≥1-year prognosis in TAVI patients. Randomized controlled or observational studies (prospective/retrospective) investigating all-cause mortality in older (≥70 years) TAVI patients were identified (PubMed; May 2020). In total, 79 studies investigating frailty with 49 different assessments were included. As single markers of frailty, mostly gait speed (23 studies) and serum albumin (16 studies) were used. Higher risk of 1-year mortality was predicted by slower gait speed (highest Hazard Ratios (HR): 14.71; 95% confidence interval (CI) 6.50–33.30) and lower serum albumin level (highest HR: 3.12; 95% CI 1.80–5.42). Composite indices (five items; seven studies) were associated with 30-day (highest Odds Ratio (OR): 15.30; 95% CI 2.71–86.10) and 1-year mortality (highest OR: 2.75; 95% CI 1.55–4.87). In conclusion, single markers of frailty, in particular gait speed, were widely used to predict 1-year mortality. Composite indices were appropriate, as well as a comprehensive assessment of frailty.

Abstract
INTRODUCTION Recently, transcatheter aortic valve replacement (TAVR) has emerged as established standard treatment for symptomatic severe aortic stenosis, providing an effective, less-invasive alternative to open cardiac surgery for inoperable or high-risk older patients. EVIDENCE ACQUISITION In order to assess the anticipated benefit of aortic replacement, considerable interest now lies in better identifying factors likely to predict outcome. In the elderly population frailty and medical comorbidities have been shown to significantly predict mortality, functional recovery and quality of life after transcatheter aortic valve replacement. Scientific literature focused on the three items will be discussed. EVIDENCE SYNTHESIS High likelihood of futility is described in patients with severe chronic lung, kidney, liver disease and/or frailty. The addition of frailty components to conventional risk prediction has been shown to result in improved discrimination for death and disability following the procedure and identifies those individuals least likely to derive benefit. Several dedicated risk score have been proposed to provide new insights into predicted "futile" outcome. However, assessment of frailty according to a limited number of variables is not sufficient, while a multi-dimensional geriatric assessment significantly improves risk prediction. CONCLUSIONS A multidisciplinary heart team that includes geriatricians can allow the customization of therapeutic interventions in elderly patients to optimise care and avoid futility.

Abstract
Background This study aimed to investigate the improvement of pulmonary function in heart failure patients with restrictive patterns undergoing transcatheter aortic valve replacement (TAVR). Methods A total of 80 patients with heart failure and restrictive patterns undergoing TAVR due to severe aortic stenosis were included in this study. Spirometry and gas diffusion were assessed before and 4–6 months after TAVR. Pre- and post-TAVR measures were compared using paired t-tests. Results Spirometry demonstrated increased absolute and percentage predicted total lung capacity (TLC), forced vital capacity (FVC), residual volume (RV), forced expiratory volume in the first second (FEV1), and forced vital capacity (FVC). FEV1/FVC decreased due to a pronounced increase in FVC. Additionally, the diffusing capacity for carbon monoxide (DLCO) increased significantly. Conclusion Pulmonary function improves in heart failure patients with restrictive patterns undergoing TAVR.

Abstract
OBJECTIVE This study investigates physical, nutritional and psychological components of frailty in predicting postoperative mortality after transcatheter aortic valve implantation (TAVI). METHODS A single centre retrospective observational study was conducted from July 2015 until January 2019. Psychological, nutritional and physical components of frailty were measured. Sarcopenia was defined as having both gait speed and grip strength under the threshold. The primary endpoint was the cumulative all-cause 1-year mortality. Secondary endpoint was 30 days all-cause mortality. RESULTS A total of 125 patients were included. The primary endpoint was observed in 18 patients (14.4%). Five patients died within the first 30 days (4.0%). None of the frailty tests were correlated with early mortality. However, at one year, the nutritional components albumin and Mini Nutritional Assessment - short form (MNA-SF) and the physical components gait speed, chair stand test, TUG, SPPB, EFT and sarcopenia were associated with increased mortality after TAVI. A significant difference in mortality was present if stratified for MNA-SF (log-rank p = .008), sarcopenia (log-rank p < .001), SPPB (log-rank p = .003) and EFT score (log-rank p < .001). CONCLUSIONS Mainly nutritional and physical components of frailty were associated with 1-year mortality after TAVI.

Abstract
Age is an independent risk factor for cardiovascular disease. With the accelerated growth of the population of older adults, geriatric and cardiac care are becoming increasingly entwined. Although cardiovascular disease in younger adults often occurs as an isolated problem, it is more likely to occur in combination with clinical challenges related to age in older patients. Management of cardiovascular disease is transmuted by the context of multimorbidity, frailty, polypharmacy, cognitive dysfunction, functional decline, and other complexities of age. This means that additional insight and skills are needed to manage a broader range of relevant problems in older patients with cardiovascular disease. This review covers geriatric conditions that are relevant when treating older adults with cardiovascular disease, particularly management considerations. Traditional practice guidelines are generally well suited for robust older adults, but many others benefit from a relatively more personalized therapeutic approach that allows for a range of medical circumstances and idiosyncratic goals of care. This requires weighing of risks and benefits amidst the patient's aggregate clinical status and the ability to communicate effectively about this with patients and, where appropriate, their care givers in a process of shared decision making. Such a personalized approach can be particularly gratifying, as it provides opportunities to optimize an older patient's function and quality of life at a time in life when these often become foremost therapeutic priorities.

Multidimensional Prognostic Index and Outcomes in Older Patients Undergoing Transcatheter Aortic Valve Implantation: Survival of the Fittest. J Clin Med 2021; 10:jcm10163529. [PMID: 34441825 PMCID: PMC8397063 DOI: 10.3390/jcm10163529] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 07/31/2021] [Accepted: 08/09/2021] [Indexed: 01/22/2023] Open
Abstract
Selecting patients with a high chance of endured benefit from transcatheter aortic valve implantation (TAVI) is becoming relevant with changing indications and increasing number of TAVI being performed. The aim of our study was to investigate the association of the multidimensional prognostic index (MPI) based on a comprehensive geriatric assessment (CGA) on survival. The TAVI Care & Cure program is a prospective, observational registry of patients referred for TAVI at the Erasmus MC University Medical Center. Consecutive patients who underwent a complete CGA and TAVI were included. CGA components were used to calculate the MPI score. The impact of the MPI score on survival was evaluated using Cox regression. Furthermore, 376 patients were included, 143 (38.0%) patients belonged to the MPI-1 group and 233 (61.9%) patients to the MPI-2–3 group. After 3 years, 14.9% of the patients in the MPI-1 group and 30.5% of the patients in the MPI-2–3 group died (p = 0.001). Patients in MPI-1 had increased chances of overall survival in comparison with patients in MPI group 2–3 Hazard Ratio (HR) 0.57, (95% Confidence Interval (CI) 0.33–0.98)). In this study we found that the MPI tool could be useful to assess frailty and to predict which patient will have a higher chance of enduring benefit from a TAVI procedure.

Cardiac Rehabilitation in German Speaking Countries of Europe-Evidence-Based Guidelines from Germany, Austria and Switzerland LLKardReha-DACH-Part 2. J Clin Med 2021; 10:jcm10143071. [PMID: 34300237 PMCID: PMC8306118 DOI: 10.3390/jcm10143071] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 06/29/2021] [Accepted: 07/05/2021] [Indexed: 02/08/2023] Open
Abstract
Background: Scientific guidelines have been developed to update and harmonize exercise based cardiac rehabilitation (ebCR) in German speaking countries. Key recommendations for ebCR indications have recently been published in part 1 of this journal. The present part 2 updates the evidence with respect to contents and delivery of ebCR in clinical practice, focusing on exercise training (ET), psychological interventions (PI), patient education (PE). In addition, special patients’ groups and new developments, such as telemedical (Tele) or home-based ebCR, are discussed as well. Methods: Generation of evidence and search of literature have been described in part 1. Results: Well documented evidence confirms the prognostic significance of ET in patients with coronary artery disease. Positive clinical effects of ET are described in patients with congestive heart failure, heart valve surgery or intervention, adults with congenital heart disease, and peripheral arterial disease. Specific recommendations for risk stratification and adequate exercise prescription for continuous-, interval-, and strength training are given in detail. PI when added to ebCR did not show significant positive effects in general. There was a positive trend towards reduction in depressive symptoms for “distress management” and “lifestyle changes”. PE is able to increase patients’ knowledge and motivation, as well as behavior changes, regarding physical activity, dietary habits, and smoking cessation. The evidence for distinct ebCR programs in special patients’ groups is less clear. Studies on Tele-CR predominantly included low-risk patients. Hence, it is questionable, whether clinical results derived from studies in conventional ebCR may be transferred to Tele-CR. Conclusions: ET is the cornerstone of ebCR. Additional PI should be included, adjusted to the needs of the individual patient. PE is able to promote patients self-management, empowerment, and motivation. Diversity-sensitive structures should be established to interact with the needs of special patient groups and gender issues. Tele-CR should be further investigated as a valuable tool to implement ebCR more widely and effectively.

Frailty in patients with aortic stenosis awaiting intervention. Intern Med J 2021; 51:319-326. [PMID: 31908088 DOI: 10.1111/imj.14737] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Revised: 12/07/2019] [Accepted: 12/21/2019] [Indexed: 01/12/2023]
Abstract
Aortic stenosis (AS) is a common valvular disease in older age. Definitive interventions include surgical aortic valve replacement or transcatheter aortic valve implantation (TAVI). In high-risk patients, frailty is observed in up to 50% awaiting TAVI. Frailty is now an established predictor of outcomes in patients with AS who undergo intervention. There is currently no consensus definition for frailty. It is widely described as a syndrome of loss in physiological reserve predisposing to increased vulnerability for death or dependency. Frailty encompasses a holistic view including domains of physical function, cognition, depression, nutrition and medical comorbidities. Individual components of frailty have been shown to significantly predict mortality, functional recovery and quality of life after TAVI. The addition of frailty components to conventional risk prediction models traditionally used in cardiac surgery has been shown to augment overall prediction for post-operative mortality and morbidity. Identifying patients who are frail at baseline provides an opportunity to modify dynamic aspects of frailty prior to, and after definitive intervention for AS. A multidisciplinary approach including comprehensive geriatric pre-operative assessment will likely become standard of care to identify and optimise frail patients awaiting TAVI. In this review, we discuss the definition and measurement of frailty in patients with AS, evaluate recent data on risk prediction associated with frailty, and outline approaches to optimisation of dynamic components of frailty to improve outcomes after AS intervention.

Abstract
Over recent years, managing hypertension in older people has gained increasing attention, with particular reference to very old, frailer individuals. In these patients, hypertension treatment may be challenging due to a higher risk of hypotension-related adverse events which commonly overlaps with a higher cardiovascular risk. Additionally, frailer older adults rarely satisfy inclusion criteria of randomized clinical trials, which determines a substantial lack of scientific data. Although limited, available evidence suggests that the association between blood pressure and adverse outcomes significantly varies at advanced age according to frailty status. In particular, the negative prognostic impact of hypertension seems to attenuate or even revert in individuals with older biological age, e.g. patients with disability, cognitive impairment, and poor physical performance. Consequently, one size doesn't fit all and personalized treatment strategies are needed, customized to individuals' frailty and functional status. Similar to other cardiovascular diseases, hypertension management in older people should be characterized by a geriatric approach based on biological rather than chronological age and a geriatric comprehensive evaluation including frailty assessment is required to provide the most appropriate treatment, tailored to patients' prognosis and health care goals. This review illustrates the importance of a patient-centered geriatric approach to hypertension management in older people with the final purpose to promote a wider implementation of frailty assessment in routine practice.

Frailty Scores and Their Utility in Older Patients with Cardiovascular Disease. ACTA ACUST UNITED AC 2021; 16:e05. [PMID: 33897831 PMCID: PMC8054346 DOI: 10.15420/icr.2020.18] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Accepted: 12/09/2020] [Indexed: 12/13/2022]
Abstract
The world’s population is ageing, resulting in more people with frailty receiving treatment for cardiovascular disease (CVD). The emergence of novel interventions, such as transcatheter aortic valve implantation, has also increased the proportion of older patients being treated in later stages of life. This increasing population burden makes the assessment of frailty of utmost importance, especially in patients with CVD. Despite a growing body of evidence on the association between frailty and CVD, there is no consensus on the optimal frailty assessment tool for use in clinical settings. Previous studies have shown limited concordance between validated frailty instruments. This review evaluates the evidence on the utility of frailty assessment tools in patients with CVD, and the effect of frailty on different outcomes measured.

Abstract
Introduction: Over the last decade, transcatheter aortic valve replacement (TAVR) has emerged as a treatment option for most patients with severe symptomatic aortic stenosis (AS). With growing indications and exponential increase in the number of TAVR procedures, it is important to be able to accurately predict mortality after TAVR.Areas covered: Herein, we review the surgical and TAVR-specific mortality prediction models (MPMs) and their performance in their original derivation and external validation cohorts. We then discuss the role of other important risk assessment tools such as frailty, echocardiographic parameters, and biomarkers in patients, being considered for TAVR.Expert opinion: Conventional surgical MPMs have suboptimal predictive performance and are mis-calibrated when applied to TAVR populations. Although a number of TAVR-specific MPMs have been developed, their utility is also limited by their modest discriminative ability when applied to populations external to their original derivation cohorts. There is an unmet need for robust TAVR MPMs that accurately predict post TAVR mortality. In the interim, heart teams should utilize the currently available TAVR-specific MPMs in conjunction with other prognostic factors, such as frailty, echocardiographic or computed tomography (CT) imaging parameters, and biomarkers for risk assessment of patients, being considered for TAVR.

Frailty is highly prevalent in specific cardiovascular diseases and females, but significantly worsens prognosis in all affected patients: A systematic review. Ageing Res Rev 2021; 66:101233.

Abstract
Cardiologists are more often confronted with older (>60 years) cardiovascular disease (CVD) patients. These patients have particular needs in clinical care because, for example, of frailty. However, it remains to be established what is the prevalence of frailty in different CVD's and how it relates to mortality. In this systematic review studies were included if they: (i) examined subjects (men and women) aged ≥60 years who suffered from any CVD with or without cardiac surgery, (ii.) examined the presence of frailty with a well-defined frailty tool and (iii.) reported prevalence rates of frailty. From thirty studies comprising 96.841 participants, it is found that 1. Frailty is highly common in older patients with CVD (in particular in females (approximately 1.6 times more than in males), in heart failure (up to 80 % of patients) and aortic valve disease (up to 74 % of patients)), and 2. Frailty is related to a 2.5-3.5-fold elevated mortality risk, even in patients with less severe CVD (e.g. percutaneous coronary intervention). Moreover, there is a lack of consistency on how to assess frailty as up to 20 different tools/assessment batteries are currently used. It is concluded that frailty should be assessed in all older CVD patients in a uniform manner to enhance clinical care and outcomes.

Abstract
BACKGROUND Limited data are available regarding change in the nutritional status after transcatheter aortic valve replacement (TAVR). This study evaluated the prognostic impact of the change in the geriatric nutritional risk index following TAVR. METHODS TAVR patients were analyzed in a prospective and observational study. To analyze the change in nutritional status, geriatric nutritional risk index of the patients was calculated on the day of TAVR and at 3-month follow-up. The impact of the change in nutritional risk index after TAVR on all-cause mortality, heart failure hospitalization (HF-h), and the composite of all-cause death and HF hospitalization was analyzed using the Cox Proportional Hazards model. RESULTS Four hundred thirty-three patients were included. After TAVR, 68.4% (n=182) patients with baseline nutritional risk improved compared with 31.6% (n=84) who remained at nutritional risk. The change from no-nutritional risk to nutritional risk after TAVR occurred in 15.0% (n=25), while 85.0% (n=142) remained without risk of malnutrition. During follow-up, 157 (36.3%) patients died and 172 patients (39.7%) were hospitalized due to HF. Patients who continued to be at nutritional risk had a higher risk of mortality (hazard ratio [HR], 2.10 [95% CI, 1.30-3.39], P=0.002), HF-h (HR, 1.97 [95% CI, 1.26-3.06], P=0.000), and the composite of death and HF-h (HR, 2.0 [95% CI, 1.37-2.91], P<0.001). The change to non-nutritional risk after TAVR significantly impacted mortality (HR, 0.48 [95% CI, 0.30-0.78], P=0.003), HF-h (HR, 0.50 [95% CI, 0.34-0.74], P=0.001), and the composite outcome (HR, 0.44 [95% CI, 0.32-0.62], P<0.001). CONCLUSIONS Remaining at nutritional risk after TAVR confers a poor prognosis and is associated with an increased risk of mortality and HF-h, while the change from risk of malnutrition to non-nutritional risk after TAVR was associated with a halving of the risk of mortality and HF-h. Further studies are needed to identify whether patients at nutritional risk would benefit from nutritional intervention during processes of care of TAVR programs.

Baseline frailty status and outcomes important for shared decision-making in older adults receiving transcatheter aortic valve implantation, a prospective observational study. Aging Clin Exp Res 2021; 33:345-352.

Abstract
AIMS The objective of this study was to examine baseline frailty status (including cognitive deficits) and important clinical outcomes, to inform shared decision-making in older adults receiving transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS We conducted a prospective, observational study of 82 TAVI patients, recruited 2013 to 2015, with 2-year follow-up. Mean age was 83 years (standard deviation (SD) 4.7). Eighteen percent of the patients were frail, as assessed with an 8-item frailty scale. Fifteen patients (18%) had a Mini-Mental Status Examination (MMSE) score below 24 points at baseline, indicating cognitive impairment or dementia and five patients had an MMSE below 20 points. Mean New York Heart Association (NYHA) class at baseline and 6 months was 2.5 (SD 0.6) and 1.4 (SD 0.6), (p < 0.001). There was no change in mean Nottingham Extended Activities of Daily Living (NEADL) scale between baseline and 6 months, 54.2 (SD 11.5) and 54.5 (SD 10.3) points, respectively, mean difference 0.3 (p = 0.7). At 2 years, six patients (7%) had died, four (5%, n = 79) lived in a nursing home, four (5%) suffered from disabling stroke, and six (7%) contracted infective endocarditis. CONCLUSIONS TAVI patients had improvement in symptoms and maintenance of activity of daily living at 6 months. They had low mortality and most patients lived in their own home 2 years after TAVI. Complications like death, stroke, and endocarditis occurred. Some patients had cognitive impairment before the procedure which might influence decision-making. Our findings may be used to develop pre-TAVI decision aids.

Impact of perioperative change in physical function on midterm outcomes after transcatheter aortic valve implantation. Heart Vessels 2021; 36:1072-1079.

Abstract
Preoperative frailty diminishes the potential for functional recovery after transcatheter aortic valve implantation (TAVI). However, perioperative changes in physical status and their impact on prognosis after TAVI have not previously been reported. Therefore, this study aimed to investigate whether perioperative changes in physical function affect prognosis in patients undergoing TAVI. We retrospectively reviewed 257 patients who underwent TAVI. The Short Physical Performance Battery (SPPB), an objective physical status assessment tool, was evaluated pre- and post-TAVI. Patients were divided into two groups: (i) patients whose SPPB score declined in the perioperative period (the decline group) and (ii) patients whose SPPB score did not decline in the perioperative period (the non-decline group). The primary endpoint was unplanned hospitalization owing to heart failure or cardiovascular death following TAVI. The mean follow-up period was 385 ± 151 days, mean age was 83.2 ± 5.8 years, and 67% of the patients were women. Sixteen patients required readmission owing to heart failure, and seven experienced cardiovascular-related death. Kaplan-Meier analysis revealed that the event-free rate was significantly lower in the decline group (log-rank, p = 0.006). A stepwise multivariate logistic regression analysis showed that a perioperative change in SPPB was significantly associated with primary endpoints (odds ratio, 1.51; 95% confidence interval, 1.12-2.04). Perioperative change in physical function was an independent risk factor for heart failure, hospitalization, or cardiovascular death following TAVI.

Abstract
BACKGROUND In older patients, sarcopenia is a prevalent disease associated with negative outcomes. Sarcopenia has been investigated in patients undergoing transcatheter aortic valve implantation (TAVI), but the criteria for diagnosis of the disease are heterogeneous. This systematic review of the current literature aims to evaluate the prevalence of sarcopenia in patients undergoing TAVI and to analyse the impact of sarcopenia on clinical outcomes. METHODS A comprehensive search of the literature has been performed in electronic databases from the date of initiation until March 2020. Using a pre-defined search strategy, we identified studies assessing skeletal muscle mass, muscle quality and muscle function as measures for sarcopenia in patients undergoing TAVI. We evaluated how sarcopenia affects the outcomes mortality at ≥1 year, prolonged length of hospital stay, and functional decline. RESULTS We identified 18 observational studies, enrolling a total number of 9'513 patients. For assessment of skeletal muscle mass, all included studies used data from computed tomography. Cut-off points for definition of low muscle mass were heterogeneous, and prevalence of sarcopenia varied between 21.0% and 70.2%. In uni- or multivariate regression analysis of different studies, low muscle mass was found to be a significant predictor of mortality, prolonged length of hospital stay, and functional decline. No interventional study was identified measuring the effect of nutritional or physiotherapy interventions on sarcopenia in TAVI patients. CONCLUSIONS Sarcopenia is highly prevalent among patients undergoing TAVI, and negatively affects important outcomes. Early diagnosis of this condition might allow a timely start of nutritional and physiotherapy interventions to prevent negative outcomes in TAVI patients.

Abstract
Hypertension management is challenging in frail older adults. The balance between treatment risks and benefits may be difficult to achieve due to an increased vulnerability to treatment-related adverse events, and limited evidence is available to support clinical decisions. The effects of frailty on blood pressure are unclear, as well as its impact on antihypertensive treatment benefits. Appropriate blood pressure targets in frail patients are debated and the frailty measure which best inform clinical decisions in hypertensive patients has yet to be identified. Therefore, hypertension management in frail older adults still represents a 'gap in evidence'. Knowledge of currently available literature is a fundamental prerequisite to develop future research and may help to implement frailty assessment and improve hypertension management in this vulnerable population. Given these premises, we present a narrative review illustrating the most relevant issues that are a matter of debate and that should be addressed in future studies.

Evolution of Basic Activities of Daily Living Function in Older Patients One Year After Transcatheter Aortic Valve Implantation. J Am Geriatr Soc 2020; 69:500-505.

Abstract
BACKGROUND/OBJECTIVES To assess the course and prediction of basic activities of daily living (ADL) function in patients after transcatheter aortic valve implantation (TAVI). DESIGN This was a prospective cohort study. SETTING The setting was a single academic center in Switzerland. PARTICIPANTS Participants included individuals aged ≥70 years (n = 330) undergoing TAVI. MEASUREMENTS A frailty index (based on geriatric assessment) and cardiac risk scores (EuroSCORE, Society of Thoracic Surgeons [STS] score) were determined in patients before TAVI. Basic ADL function was measured with patient or proxy interviews at baseline and 1-year follow up. We used logistic regression models to investigate the association between baseline factors and functional decline. RESULTS At 1-year follow up, 229 (69.4%) of the 330 patients had stable or improved basic ADL function, 49 (14.8%) experienced a decline in basic ADL function, and 52 (15.8%) died. The frailty index, but not cardiac risk scores, significantly predicted decline in basic ADL function. Among the 34 surviving very frail patients, 12 (35.3%) experienced a functional status decline, and the remaining 22 (64.7%) had stable or improved functional status at 1-year follow up. CONCLUSION This study confirms that a frailty index, and not cardiac risk scores, identifies patients at an increased risk of functional status decline after TAVI. Identifying patients with a high frailty index before TAVI is clinically relevant as these patients might benefit from targeted geriatric management and rehabilitation after TAVI. However, based on current data, it is not justified to use information on frailty status as the criterion for identifying patients in whom TAVI might be futile. Although the probability of poor outcome is high, very frail patients also have a high probability of favorable long-term functional outcome.

Delirium, functional decline and quality of life after transcatheter aortic valve implantation: An explorative study. Geriatr Gerontol Int 2020; 20:1202-1207.

Abstract
AIM Transcatheter aortic valve implantation (TAVI) has become an important treatment option for older patients with severe aortic stenosis. However, not all patients benefit from this procedure in terms of functional outcome and quality of life. This complicates patient selection and shared decision-making. Postoperative delirium might negatively affect patient outcomes after TAVI. We therefore studied the potential relationship between postoperative delirium and functional outcome, and how this impacts quality of life after TAVI. METHODS This was a prospective cohort study of 91 consecutive patients undergoing TAVI between 2015 and 2017 at an academic medical center. All patients underwent a Comprehensive Geriatric Assessment before TAVI. Delirium symptoms were assessed daily during hospitalization. Follow up was carried out between 6 and 12 months postprocedure. The primary outcome was functional decline or death at follow up. Secondarily, we measured quality of life at follow up. RESULTS The incidence of postoperative delirium was 15.4%. In total, 38.5% of patients experienced functional decline, and 11.0% died during a median follow-up period of 7 months. Delirium resulted in a fourfold increased odds of the combined outcome of functional decline or death. Quality of life was lower in patients that experienced this outcome. CONCLUSION In a cohort of TAVI patients, functional decline or death was a frequent outcome in the first year postprocedure. Postoperative delirium increased the odds for this outcome substantially. This suggests that delirium risk should be an important factor to consider in shared decision-making for TAVI patients. Geriatr Gerontol Int 2020; 20: 1202-1207.

Abstract
BACKGROUND The association of geriatric syndromes and economic outcomes among patients who are undergoing transcatheter aortic valve replacement (TAVR) remains unknown. METHODS AND RESULTS A retrospective observational study using the National Inpatient Sample (NIS) from 2011 to 2014 was conducted with 7078 patients who were 65 years or older and underwent TAVR. The average hospital cost was US$58 703 (± SD 29 777) and length of stay (LOS) was 8.1 days (±7.20). The rates of delirium, dementia, and frailty were 8.0%, 6.1%, and 10.5%, respectively. From a multivariable generalized linear regression, delirium increased the cost by 31.5% (95% CI 25.41~37.92) and LOS by 70.3% (95% CI 60.20~83.38). Frailty increased the cost by 7.4% (95% CI 3.44~11.53) and the LOS by 22.6% (95% CI 15.15~30.55). Dementia had no significant association with either outcome. When the interactions of the geriatric syndromes were tested for association with the outcomes, delirium in the absence of dementia but presence of frailty showed the strongest association with cost (increase by 45.1%, 95% CI 26.45~66.45), and delirium in the absence of both dementia and frailty showed the strongest association with LOS (increase by 74.5%, 95% CI 62.71~87.13). When the average hospital cost and LOS were predicted using the model with interaction terms, patients with delirium and frailty (but without dementia) had the highest value (total hospital cost US$86 503 and LOS 14.9 days). CONCLUSION Among TAVR patients, delirium was significantly associated with increased hospital cost and LOS, and the association was significantly higher in the absence of dementia. The results of this study will be a great asset for health care providers and administrators in planning for efficient care strategy to lower health care expenditure in the hospital for older adults who underwent TAVR.

Growth Differentiation Factor 15 in Severe Aortic Valve Stenosis: Relationship with Left Ventricular Remodeling and Frailty. J Clin Med 2020; 9:jcm9092998. [PMID: 32957481 PMCID: PMC7564755 DOI: 10.3390/jcm9092998] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 09/06/2020] [Accepted: 09/15/2020] [Indexed: 12/15/2022] Open
Abstract
Background: Frailty is an important outcome predictor in patients with aortic stenosis who are candidates for transcatheter or surgical aortic valve replacement (AVR). Growth/differentiation factor 15 (GDF15) is a cytokine playing a role in the pathophysiology of ventricular remodeling. We assessed its potential role as an independent soluble biomarker of frailty in these patients. Methods: We studied 62 patients (age, mean 79 years, 95% confidence interval (CI) 77-81; 54.8% female) with severe aortic valve stenosis and candidates for AVR. We systematically assessed pre-intervention GDF15 levels for their relationship with frailty (Katz score) and echocardiographic parameters of left ventricular dysfunction/remodeling. Fifteen hypertensive patients with left ventricular (LV) hypertrophy served as controls. Results: Patients with aortic valve stenosis featured higher GDF15 levels than controls (1773, 95% CI 1574-1971 pg/mL vs. 775, 95% CI 600-950 pg/mL, respectively, p < 0.0001). Subjects in the upper GDF15 tertile were older (p = 0.004), with a more advanced NYHA functional class (p = 0.04) and a higher prevalence of impaired renal function (p = 0.004). Such patients also showed a higher frailty score (p = 0.04) and higher indices of LV dysfunction, including reduced global longitudinal strain (p = 0.01) and a higher left ventricular mass (p = 0.001). GDF15 was significantly related to the Katz score, and predicted (OR 1.05; 95% CI 0.9-1.1; p = 0.03) a low (<5) Katz score, independent of the relationship with LV mass, age, renal function or indices of LV dysfunction. Conclusions: GDF15 is increased in patients with severe aortic stenosis and appears to be a soluble correlate of patients' frailty, independent of indices of left ventricular dysfunction.
