Geriatric cardiac surgery: chronology vs. biology

Outcomes of Octogenarians Undergoing Edge-to-Edge Transcatheter Valve Repair for Tricuspid Regurgitation: Inverse Propensity Score-Weighted Analysis

There is a scarcity of data for perioperative outcomes of octogenarians undergoing tricuspid transcatheter edge-to-edge repair (TEER), despite both the potential procedural effectiveness in treating tricuspid regurgitation and a low incidence of severe complications observed in the nonelderly population. We assessed the characteristics and outcomes of TEER in octogenarians compared to those in patients under 80 years old treated at a referral tertiary teaching hospital. We retrospectively enrolled all adult patients undergoing tricuspid TEER. The population was stratified based on age: ≥80 and <80 years. Inverse probability of treatment weighting (IPTW) propensity score was used to mitigate the risk of selection bias. Between January 2017 and September 2023, 101 patients underwent tricuspid TEER. Thirty-six (36%) were octogenarians. Crude treatment estimates indicated that preoperative Tricuspid Annular Plane Systolic Excursion (TAPSE) was significantly higher in octogenarians compared to younger patients (19 mm [IQR: 17 to 21] vs. 17 mm [IQR: 14-18]; p = 0.005). At discharge, octogenarians showed a TAPSE 2.71 mm higher than that observed in the <80 age group (95% CI: 0.79 to 4.62; p = 0.006) according to crude treatment estimates. After adjusting with IPTW-weighting, the TAPSE difference remained significant, with octogenarians having a 2.44 mm higher TAPSE (95% CI: 0.54 to 4.35; p = 0.012). IPTW-adjusted analyses indicated comparable clinical outcomes between the two groups. Adverse events and survival in octogenarians were similar to those observed in patients aged <80 years. Our findings indicate that age alone should not be the sole criterion to deny TEER.

Breaking the Cycle: Enhancing Cardiovascular Health in the Elderly Through Group Exercise

The global increase in aging populations underscores the urgency of addressing cardio-kidney metabolic health indicators, particularly among sedentary elderly individuals. This study investigates the impact of an 8-month structured group exercise program on cardiovascular health indicators among 320 women aged 60 and older living independently in Rijeka. Participants engaged in biweekly sessions designed to improve mobility, balance, and strength. Key metrics, including blood pressure (BP), body mass index (BMI), waist-to-hip (WHR) and waist-to-height ratio (WHtR), and hand grip strength, were measured before and after the intervention. Results revealed significant reductions in systolic blood pressure (mean -3.4 mmHg) and pulse pressure among hypertensive participants, highlighting improved cardiovascular function. BP control significantly improved (7.2%), and 19% of untreated hypertensive subjects at the start become normotensive at the end of follow-up. Although BMI changes were minimal, WHtR improvements indicated reductions in central obesity and muscle fat redistribution. Hand grip strength increased significantly on both arms, correlating with physical capacity. The results underline the benefits of group training for improving health even in the elderly population through an organized exercise program. While these preliminary results demonstrate promising health improvements, further research with longer follow-up and inclusion of diverse participant groups is recommended to validate these outcomes and refine intervention strategies.

Hospital Discharge Process: Context-Sensitive Care

The transition from hospital to home after surgery is a vulnerable time for all cardiac surgical patients, particularly older adults. This postoperative phase presents multiple physical, physiological, emotional, and socioeconomic challenges, not only for patients but also for their families and informal caregivers, who often describe this period as stressful and overwhelming. Health-care professionals, particularly nurses, play an integral role in a patient's discharge process; the challenges can be ameliorated through timely discharge planning and effective discharge education. The context-sensitive solutions shared in this paper propose enhancing nurses' discharge practices to provide individualized care and to facilitate the hospital-to-home transition.

Anxiety and depression in patients aged 80 years and older following aortic valve therapy. A six-month follow-up study

BACKGROUND

Little is known about mental health following advanced cardiac procedures in the oldest patients.

AIMS

To study changes in anxiety and depression from baseline to one- and six-month follow-up in older patients following transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR).

METHODS

Prospective cohort study of patients ≥ 80 years undergoing elective TAVI or SAVR in a tertiary university hospital. Anxiety and depression were assessed with the Hospital Anxiety and Depression Scale. Differences between TAVI/SAVR were analyzed using Welch's t test or chi-squared. Changes over time and group differences were established with longitudinal models using generalized least squares.

RESULTS

In 143 patients (83.5 ± 2.7 years), 46% (n = 65) received TAVI. Anxiety was identified in 11% of TAVI patients at baseline. One- and six-months later, percentages were 8% and 9%. In SAVR patients, 18% had baseline scores indicating anxiety. One and six-months later, percentages were 11% and 9%. Depression was identified in 15% of TAVI patients. One- and six-months later, percentages were 11% and 17%. At baseline, 11% of SAVR patients had scores indicating depression. One- and six-months after SAVR, percentages were 15% and 12%. Longitudinal analyses showed reductions (P < 0.001) in anxiety from baseline to one-month, and stable scores between one- and six-months for both treatment groups. There was no change over time for depression among treatment groups (P = 0.21).

DISCUSSION AND CONCLUSIONS

SAVR or TAVI in patients ≥ 80 years was associated with anxiety reduction between baseline and follow-up. For depression, there was no evidence of change over time in either treatment group.

Living arrangements and depression of the older adults- evidence from the Chinese longitudinal healthy longevity survey

BACKGROUND

The mental health and living arrangements of older adults are worthy of attention. Previous studies have pointed out that the living arrangements may be related to older adults' depression. However, it has not been found that studies concern the relationship between actual living arrangements, living arrangement preferences, and the fit between living arrangement preferences and reality and depression in older adults, so we carried out this study.

METHODS

The data from the Chinese longitudinal healthy longevity survey were used in this study. With the older adults' depression as the dependent variable and the living arrangement related variables as the independent variable, we constructed three binary-logistic regression analysis models to explore the potential relationship between living arrangement related variables and depression in older adults.

RESULTS

We found that the actual living arrangements, living arrangement preferences, and the fit between living arrangement preferences and reality are significantly correlated with depression in older adults. Specifically, older adults living alone or only with the spouse are at greater risk of depression. Older adults who prefer living alone or only with the spouse are at relatively low risk of depression. Older adults whose living arrangement preferences do not match reality have a higher risk of depression.

CONCLUSION

The living arrangement related variables are significantly correlated with depression in older adults. In addition to the actual living arrangements, living arrangement preferences and whether the living arrangement preferences fit with reality are also related to the depression of older adults.

Cardiovascular Risk Factors and Physical Activity for the Prevention of Cardiovascular Diseases in the Elderly

Cardiovascular diseases create an important burden on the public health systems, especially in the elderly, mostly because this group of patients frequently suffer from multiple comorbidities. Accumulating cardiovascular risk factors during their lifetime has a detrimental effect on an older adult's health status. The modifiable and non-modifiable cardiovascular risk factors are very diverse, and are frequently in a close relationship with the metabolic comorbidities of the elderly, mainly obesity and Diabetes Mellitus. In this review, we aim to present the most important cardiovascular risk factors which link aging and cardiovascular diseases, starting from the pathophysiological links between these factors and the aging process. Next, we will further review the main interconnections between obesity and Diabetes Mellitus and cardiovascular diseases of the elderly. Lastly, we consider the most important aspects related to prevention through lifestyle changes and physical activity on the occurrence of cardiovascular diseases in the elderly.

Guidelines for enhanced recovery after cardiac surgery. Consensus document of Spanish Societies of Anesthesia (SEDAR), Cardiovascular Surgery (SECCE) and Perfusionists (AEP)

The ERAS guidelines are intended to identify, disseminate and promote the implementation of the best, scientific evidence-based actions to decrease variability in clinical practice. The implementation of these practices in the global clinical process will promote better outcomes and the shortening of hospital and critical care unit stays, thereby resulting in a reduction in costs and in greater efficiency. After completing a systematic review at each of the points of the perioperative process in cardiac surgery, recommendations have been developed based on the best scientific evidence currently available with the consensus of the scientific societies involved.

Octogenarians and aortic valve surgery: surgical outcomes in the geriatric population

Background

The era of percutaneous aortic valve intervention has challenged the continuing indication for surgical aortic valve replacement (SAVR).

Aim

The aim of this study is to evaluate clinical outcomes of the elderly patients who underwent surgical aortic valve replacement via median sternotomy, in order to assess the impact of surgery on patient outcomes and discharge destination.

Methods

The study involves a retrospective observational analysis in a single centre, including all octogenarian patients who underwent aortic valve surgery between January of 2011 and July of 2016. The study assessed pre-operative co-morbidities and post-operative outcomes, including long-term mortality and discharge destination following on from surgery.

Results

The mean age of patients was 82.7 years (± 2.9), 67% of whom were male. The mean EuroSCORE II was 8.1 (± 7.6). The most common pre-operative co-morbidities were dyslipidaemia (82%), hypertension (80%), and ischaemic heart disease (78.8%). The median length of stay was 10 days (± 6.9 days). Discharge home occurred in 71.8% of patients, with 21.2% of patients requiring transfer to a rehabilitation facility, and 1.2% of patients required placement into an aged care facility. There were five peri-operative deaths, equating to 5.9% of the cohort.

Conclusion

Despite high EuroSCORE II values for the majority of our patients, our data adds to overall suggestions that the octogenarian population can be considered eligible for SAVR and should not be excluded due to age alone. The use of the EuroSCORE II index more accurately predicts adequacy for treatment however does not entirely predict overall course of events, and proceduralist discretion should still be used.

Definiert das Alter den geriatrischen Patienten?

Ältere Menschen stellen einen wachsenden Anteil unserer täglich medizinisch und chirurgisch zu versorgenden Patienten dar. Allerdings definiert das kalendarische Alter alleine den älteren Patienten nur unzureichend. Vielmehr scheint das biologische Alter oder das Maß an Gebrechlichkeit entscheidend für die Charakterisierung zu sein. Auch der Prozentsatz der Menschen, die gebrechlich sind, ist in den letzten Jahrzehnten stetig gestiegen. Gebrechlichkeit oder Frailty ist ein geriatrisches Syndrom, welches durch verringerte physische und psychische Reserven zur Kompensation gekennzeichnet ist. Die beiden am häufigsten genutzten Ansätze zur Definition von Gebrechlichkeit sind der phänotypische Ansatz und der Ansatz der Defizitakkumulation. Für ältere Patienten haben sich in diesem Zusammenhang 2 Interventionspunkte in der klinischen Praxis herauskristallisiert: 1. die präinterventionelle/operative Identifizierung von Hochrisikopatienten, um sowohl die Patientenerwartungen als auch die chirurgische Entscheidungsfindung zu steuern, und 2. periinterventionelle/operative Optimierungsstrategien für gebrechliche Patienten. Noch fehlt ein mit vertretbarem Zeitaufwand in der klinischen Praxis umsetzbarer, objektiver Goldstandard zur Analyse der Frailty.

Effectiveness of home-based exercise in older patients with advanced chronic obstructive pulmonary disease: A 3-year cohort study

AIM

To determine whether home-based exercise can improve clinical outcomes in older patients with advanced chronic obstructive pulmonary disease using long-term oxygen therapy.

METHODS

Information was provided to improve chronic obstructive pulmonary disease self-management before the onset of the present prospective 3-year cohort study. Patients selected either home-based exercise using a lower-limb cycle machine (ergo-bicycle; group E), or usual exercise (group U). To assess self-management, the Lung Information Needs Questionnaire was evaluated every 6 months. Clinical outcomes included the 6-min walk test, pulmonary function tests, the body mass index, airflow obstruction, dyspnea and exercise index, St. George's respiratory questionnaire, and the number of exacerbations and hospitalizations.

RESULTS

A total of 136 patients (group E = 72; group U = 64), with a mean age of 74.2 years were enrolled. Total Lung Information Needs Questionnaire scores improved over 3 years for group E (P = 0.003). The distance of the 6-min walk test was well maintained in group E, but significantly decreased in group U (P < 0.001). The percentage of forced expiratory volume in 1 s at baseline was lower in group E (P = 0.016), but was maintained over 3 years, whereas a significant reduction was seen in group U (P = 0.001). The body mass index, airflow obstruction, dyspnea and exercise index significantly worsened in both groups over 3 years (group E: P = 0.011; group U: P < 0.001), whereas a significant decrease in the number of exacerbations was noted in group E (P = 0.009).

CONCLUSIONS

Patients who undertook home-based exercise using an ergo-bicycle were able to maintain clinical outcomes including 6-min walk test distance and percentage of forced expiratory volume in 1 s predicted, and recorded fewer exacerbations over 3 years. Geriatr Gerontol Int 2018; 18: 42-49.

Cardiac surgery as a stressor and the response of the vulnerable older adult

In an aging population, recovery and restoration of function are critical to maintaining independence. Over the past 50years, there have been dramatic improvements made in cardiac surgery processes and outcomes that allow for procedures to be performed on an increasingly older population with the goal of improving function. Although improved function is possible, major surgical procedures are associated with substantial stress, which can severely impact outcomes. Past literature has identified that frail patients, who are vulnerable to the stress of surgery, are more likely to have postoperative major adverse cardiac and cerebrovascular events (OR 4.9, 95% confidence interval 1.6, 14.6). The objective of this manuscript is to examine preoperative frailty in biological, psychological, and social domains using cardiac surgery to induce stress. We systematically searched PubMed for keywords including "cardiac surgery, frailty, and aged" in addition to the biological, psychological, and social keywords. In the biological domain, we examine the association of physiological and physical vulnerabilities, as well as, the impact of comorbidities and inflammation on negative surgical outcomes. In the psychological domain, the impact of cognitive impairment, depression, and anxiety as vulnerabilities were examined. In the social domain, social structure, coping, disparities, and addiction as vulnerabilities are described. Importantly, there is substantial overlap in the domains of vulnerability. While frailty research has largely focused on discrete physical vulnerability criteria, a broader definition of frailty demonstrates that vulnerabilities in biological, psychological, and social domains can limit recovery after the stress of cardiac surgery. Identification of vulnerability in these domains can allow better understanding of the risks of cardiac surgery and tailoring of interventions to improve outcomes.

Readmissions and mortality in delirious versus non-delirious octogenarian patients after aortic valve therapy: a prospective cohort study

OBJECTIVES

To determine whether postoperative delirium predicts first-time readmissions and mortality in octogenarian patients within 180 days after aortic valve therapy with surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI), and to determine the most common diagnoses at readmission.

DESIGN

Prospective cohort study of patients undergoing elective SAVR or TAVI.

SETTING

Tertiary university hospital that performs all SAVRs and TAVIs in Western Norway.

PARTICIPANTS

Patients 80+ years scheduled for SAVR or TAVI and willing to participate in the study were eligible. Those unable to speak Norwegian were excluded. Overall, 143 patients were included, and data from 136 are presented.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was a composite variable of time from discharge to first all-cause readmission or death. Secondary outcomes were all-cause first readmission alone and mortality within 180 days after discharge, and the primary diagnosis at discharge from first-time readmission. Delirium was assessed with the confusion assessment method. First-time readmissions, diagnoses and mortality were identified in hospital information registries.

RESULTS

Delirium was identified in 56% of patients. The effect of delirium on readmissions and mortality was greatest during the first 2 months after discharge (adjusted HR 2.9 (95% CI 1.5 to 5.7)). Of 30 first-time readmissions occurring within 30 days, 24 (80%) were patients who experienced delirium. 1 patient (non-delirium group) died within 30 days after therapy. Delirious patients comprised 35 (64%) of 55 first-time readmissions occurring within 180 days. Circulatory system diseases and injuries were common causes of first-time readmissions within 180 days in delirious patients. 8 patients died 180 days after the procedure; 6 (75%) of them experienced delirium.

CONCLUSIONS

Delirium in octogenarians after aortic valve therapy might be a serious risk factor for postoperative morbidity and mortality. Cardiovascular disorders and injuries were associated with first-time readmissions in these patients.

Assessing Risks and Benefits of Invasive Cardiac Procedures in Patients with Advanced Multimorbidity

Age-related cardiovascular disease in older adults is more likely to occur in combination with other age-related diseases, with mounting interactive complexity as multiple morbidities accumulate. Although invasive cardiac procedures are frequently recommended for cardiovascular disease, their value is less certain in the context of age-related intricacies of care. Tools for risk assessment before invasive procedures are insensitive to risks corresponding to the unique challenges of older adults. Recognizing multimorbidity and other age-related risks provides opportunities to intervene and moderate dangers. By refocusing risk assessment in terms of patient-centered goals, the fundamental utility of invasive cardiac procedures may be reconsidered and alternative therapies prioritized.

Clinical Outcome and Cost Analysis of Sutureless Versus Transcatheter Aortic Valve Implantation With Propensity Score Matching Analysis

Surgical sutureless and interventional transcatheter aortic valve prostheses are nowadays extensively adopted in high-risk elderly patients. An explorative analysis was carried out to compare the clinical outcome and costs associated to these approaches. Since 2010, a total of 626 patients were distributed between transcatheter aortic valve implantation (TAVI; n = 364) and sutureless (n = 262) groups. Patients of both groups were not comparable for clinical and surgical characteristics, but many patients were in a "gray zone"; therefore, a retrospective propensity score analysis was possible and performed. For the matched pair samples, postoperative, follow-up clinical data, and costs data were obtained. In-hospital death occurred in 5 patients in sutureless group and 3 patients in TAVI group (p = 0.36). Blood transfusions were higher in sutureless group (2.1 ± 2.3 vs 0.4 ± 1.0 U). TAVI group had a shorter intensive care unit and hospital stay (2.2 ± 2.7 vs 3.2 ± 3.5 days, p = 0.037; 12 ± 6 vs 14 ± 6 days, p = 0.017). No differences in postoperative neurologic (p = 0.361), renal (p = 0.106), or respiratory (p = 0.391) complications were observed between groups. At follow-up (24.5 ± 13.8 months), 1 patient in sutureless group and 7 patients in TAVI group died (p = 0.032). Paravalvular leakage occurred more frequently in patients in TAVI group (35 [34%] vs 7 [6.9%]; p <0.001) with an impact on follow-up survival rate. The costs associated to the 2 procedures are similar when the cost of the device was excluded (p = 0.217). When included, the sutureless approach resulted a cost saving (€22,451 vs €33,877, p <0.001). In conclusion, the patients in the "gray zone" record a satisfying clinical outcome after sutureless surgery and TAVI. Patients in the sutureless group endure more hospital complications, but TAVI entails a higher follow-up mortality. On the costs aspects, TAVI technologies are more expensive, and it reflects on higher overall hospital costs.

Age as a Prognostic Factor in Patients with Acute Coronary Syndrome undergoing Urgent/Emergency Cardiac Surgery

BACKGROUND

Patients presenting with acute coronary syndrome (ACS) who require urgent/emergency coronary artery bypass grafting (CABG) are increasing, as is the complexity of their clinical characteristics, one of which is advanced age. We evaluated the prognostic role of age in patients undergoing urgent/emergency cardiac surgery for ACS.

METHODS

From January to December 2013, 452 consecutive patients underwent CABG at our institution. Among these, 213 presented with ACS, were enrolled in the study and divided into tertiles of age: First: 40-65 years old (n=73), Second: 66-74 (n=70), Third: 75-89 (n=70). Patients were followed post-operatively for 30 days.

RESULTS

No differences between tertiles were found for baseline clinical and angiographic characteristics. Off-pump interventions were 67.6%. Older patients more frequently required an associate intervention to CABG for a mechanical complication of ACS. Overall 30-day all-cause mortality was 4.7% (n=10); 0.6% (n=1) in patients undergoing isolated CABG (n=168, 78.9%). The STEMI diagnosis was an independent risk factor for 30-day mortality, and age was not.

CONCLUSIONS

The 30-day mortality rate of older ACS patients who undergo urgent/emergency CABG is comparable to that of younger ones. Pre-operative risk assessment should rely on evaluation of the clinical complexity of each patient independent of their chronological age, to customise the therapeutic strategy.
