Long-term health-related quality of life and survival after cardiac surgery: A prospective study

Depression predicts delayed return to daily activities in patients post-cardiac surgery: a prospective observational study

BACKGROUND

Depression significantly impacts recovery and return to daily activities in cardiac surgery patients. Assessing and managing depressive symptoms before and after surgery are crucial for improving surgical outcomes and timely return to daily activities, including work. The objectives of this study were to examine differences in patients' depression levels in relation to their return to daily activities in the early post-cardiac surgery period, and to assess predictors of delayed return to daily activities.

METHODS

This single-centered study assessed return to independence, social participation, hobbies, and work in 100 cardiac surgical patients at 2 and 6 weeks post-surgery. Associations between depression levels and return to daily activities scores were evaluated.

RESULTS

Higher Center for Epidemiologic Studies Depression Scale (CES-D) scores were significantly associated with delayed return to daily activities in all categories at both 2 and 6 weeks post-surgery. Specifically, higher depression score delayed return to independence and social participation at 2 weeks, and delayed return to independence, social participation, and return to work at 6 weeks.

CONCLUSION

Elevated depression scores are significantly associated with delayed return to daily activities post-cardiac surgery, indicating the importance of evaluating depression in cardiac surgical patients in the postend stage-operative period.

Quality of life and functional capacity in patients after cardiac surgery intensive care unit

Coronary heart disease and aortic stenosis are prevalent cardiovascular diseases worldwide, leading to morbidity and mortality. Coronary artery bypass grafting (CABG) and surgical aortic valve replacement (SAVR) have therapeutic benefits, including improved postoperative quality of life (QoL) and enhanced patient functional capacity which are key indicators of cardiac surgery outcome. In this article, we review the latest studies of QoL outcomes and functional capacity in patients who underwent cardiac surgery. Many standardized instruments are used to evaluate QoL and functional conditions. Preoperative health status, age, length of intensive care unit stay, operative risk, type of procedure, and other pre-, intra-, and postoperative factors affect postoperative QoL. Elderly patients experience impaired physical status soon after cardiac surgery, but it improves in the following period. CABG and SAVR are associated with increases of physical and mental health and functional capacity in the immediate postoperative and the long long-term. Cardiac rehabilitation improves patient functional capacity, QoL, and frailty following cardiac surgery.

The effect of a selenium-based anti-inflammatory strategy on postoperative functional recovery in high-risk cardiac surgery patients - A nested sub-study of the sustain CSX trial

AIM

The cardiac surgery-related ischemia-reperfusion-related oxidative stress triggers the release of cytotoxic reactive oxygen and nitrogen species, contributing to organ failure and ultimately influencing patients' short- and long-term outcomes. Selenium is an essential co-factor for various antioxidant enzymes, thereby contributing to the patients' endogenous antioxidant and anti-inflammatory defense mechanisms. Given these selenium's pleiotropic functions, we investigated the effect of a high-dose selenium-based anti-inflammatory perioperative strategy on functional recovery after cardiac surgery.

MATERIALS AND METHODS

This prospective study constituted a nested sub-study of the SUSTAIN CSX trial, a double-blinded, randomized, placebo-controlled multicenter trial to investigate the impact of high-dose selenium supplementation on high-risk cardiac surgery patients' postoperative recovery. Functional recovery was assessed by 6-min walk distance, Short Form-36 (SF-36) and Barthel Index questionnaires.

KEY FINDINGS

174 patients were included in this sub-study. The mean age (SD) was 67.3 (8.9) years, and 78.7 % of the patients were male. The mean (SD) predicted 30-day mortality by the European System for Cardiac Operative Risk Evaluation II score was 12.6 % (9.4 %). There was no difference at hospital discharge and after three months in the 6-min walk distance between the selenium and placebo groups (131 m [IQR: not performed - 269] vs. 160 m [IQR: not performed - 252], p = 0.80 and 400 m [IQR: 299-461] vs. 375 m [IQR: 65-441], p = 0.48). The SF-36 and Barthel Index assessments also revealed no clinically meaningful differences between the selenium and placebo groups.

SIGNIFICANCE

A perioperative anti-inflammatory strategy with high-dose selenium supplementation did not improve functional recovery in high-risk cardiac surgery patients.

Minimal clinically important differences in patient-reported outcomes after coronary artery bypass surgery in the arterial revascularization trial

OBJECTIVES

This article identifies minimal clinically important differences (MCIDs) in quality of life (QoL) measures among patients who had coronary artery bypass grafting (CABG) and were enrolled in the arterial revascularization trial (ART).

METHODS AND RESULTS

The European Quality of Life-5 Dimensions (EQ-5D) and the Short Form Health Survey 36-Item (SF-36) physical component (PC) and mental component (MC) scores were recorded at baseline, 5 years and 10 years in ART. The MCIDs were calculated as changes in QoL scores anchored to 1-class improvement in the New York Heart Association functional class and Canadian Cardiovascular Society scale at 5 years. Cox proportional hazard models were used to evaluate associations between MCIDs and mortality. Patient cohorts were examined for the SF-36 PC (N = 2671), SF-36 MC (N = 2815) and EQ-5D (N = 2943) measures, respectively. All QoL scores significantly improved after CABG compared to baseline. When anchored to the New York Heart Association, the MCID at 5 years was 17 (95% confidence interval: 17-20) for SF-36 PC, 14 (14-17) for the SF-36 MC and 0.12 (0.12-0.15) for EQ-5D. Using the Canadian Cardiovascular Society scale as an anchor, the MCID at 5 years was 15 (15-17) for the SF-36 PC, 12 (13-15) for the SF-36 MC and 0.12 (0.11-0.14) for the EQ-5D. The MCIDs for SF-36 PC and EQ-5D at 5 years were associated with a lower risk of mortality at the 10-year follow-up point after surgery.

CONCLUSIONS

MCIDs for CABG patients have been identified. These thresholds may have direct clinical applications in monitoring patients during follow-up and in designing new trials that include QoL as a primary study outcome.

Comparison of quality of life in patients with mitral valve replacement and mitral valve repair in Imam Ali Hospital during 2014 to 2020: a cross-sectional study

OBJECTIVE

Mitral valve failure is one of the most common valvular heart diseases worldwide. Valve replacement and repair have an impact on the quality of life of patients. Therefore, the present study was conducted to compare the quality of life in patients with mitral valve replacement and those who underwent mitral valve repair.

METHODS

In this cross-sectional study, we considered all cardiac patients with ischemic mitral insufficiency who underwent mitral valve repair and patients with a history of valve replacement in Imam Ali Hospital of Kermanshah between 2014 and 2020. Two Minnesota and general quality of life questionnaires along with a checklist for demographic variables were used for data collection. Data analysis was performed using SPSS version 21 software.

RESULTS

The mean quality of life score based on the general quality of life scale in the valve repair group was 32.33 (SD = 2.29) and in the valve replacement group 32.89(SD = 2.60), (p = 0.917). Also, mean quality of life, as measured by the Minnesota MLHFQ was 60.89(SD = 17.67) in the valve repair group and 63.42 (SD = 12.13) in the valve replacement group (p = 0.308). The results showed that the average general quality of life was different in study groups regarding education. Tukey's post hoc test showed that the average general quality of life in illiterate people is significantly lower than in people with academic degrees (P-value = 0.001).

CONCLUSION

The quality of life of the patients in both the valve repair and replacement groups was at an average level. There was no significant difference between the general quality of life and the Minnesota scales, suggesting that both tools can be effectively used to measure patients' quality of life. The study's findings can be valuable for monitoring patients, screening for conditions, and enhancing communication between doctors and patients.

Long-Term Health-Related Quality of Life following Acute Type A Aortic Dissection with a Focus on Male-Female Differences: A Cross Sectional Study

Objectives: Acute type A aortic dissection (ATAAD) is a life-threatening cardiovascular emergency, of which the long-term impact on health-related quality of life (HRQoL) and male-female-specific insights remain inadequately clarified. Methods: Consecutive adult ATAAD patients who underwent surgery were retrospectively included between 2007 and 2017 in four referral centers in the Netherlands, and baseline data were collected. The 36-Item Short-Form (SF-36) Health Survey was sent to all survivors between 2019 and 2021 and compared to validated SF-36 scores of the Dutch general population stratified by age group and sex. Results: In total, 324/555 surviving patients returned the SF-36 questionnaire (response rate 58%), of which 40.0% were female; the median follow-up was 6.5 years (range: 1.7-13.9, IQR: 4.0-9.4) after surgery for ATAAD. In comparison to the general population, ATAAD patients scored significantly lower on 6/8 SF-36 subdomains and higher on bodily pain. Differences in HRQoL domains compared to the sex-matched data were largely comparable between sexes, apart from bodily pain. In the age-matched subgroups impaired HRQoL was most pronounced in younger patients aged 41-60 (5/8 impaired domains). Female ATAAD patients scored significantly worse on 5/8 SF-36 subdomains and the physical component summary (PCS) scores than male patients. Age at ATAAD, female sex, hypertension, COPD, and prior thoracic aortic aneurysm were associated with worse PCS scores. Conclusions: Long-term HRQoL was impaired in both male and female ATAAD patients when compared to the general population. Further studies on the nature of this impairment and on interventions to improve HRQoL after ATAAD are clearly warranted, with special attention to females and younger patients.

Health Related Quality of Life Following Intervention for Thoracoabdominal Aortic Aneurysm: A Systematic Review and Narrative Synthesis

BACKGROUND

Thoracoabdominal aortic aneurysms (TAAA) pose significant risks of morbidity and mortality. Considering the evolving techniques for TAAA intervention and the growing interest in quality of life (QoL) outcomes for decision-making, we aimed to evaluate the impact of patient and perioperative characteristics on short-term, medium-term, and long-term postoperative QoL in TAAA repair patients.

METHODS

A systematic search was conducted in CINAHL, APA PsycINFO, EMBASE, Medline and Cochrane to identify primary research studies evaluating QoL post TAAA surgery, published in English or Swedish between January 01, 2012 and September 26, 2022. A narrative synthesis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The quality of evidence was assessed using the Critical Appraisal Skills Program and Joanna Briggs Institute checklists.

RESULTS

Eight studies of low or moderate quality with 455 patients were included. Preoperative QoL in TAAA patients was lower compared to the general population. While there is an initial short-term improvement in postoperative QoL, patients fail to reach baseline levels even after 7 years, with physical activity and functioning domains being particularly affected. Experiencing postoperative complications, including paraplegia and cardiovascular events, negatively impacts postoperative QoL. Patients with uncomplicated postoperative status had improved QoL. Prolonged hospital stay negatively affects physical functioning.

CONCLUSIONS

Individuals with TAAA are likely to have lower baseline QoL compared to the general population. Following TAAA repair, postoperative QoL may remain lower than baseline levels, persisting over the long-term. Comorbidities, postoperative complications, and hospitalization duration appear to exert adverse effects on postoperative QoL.

Impact of Clinical and Sociodemographic Factors on Quality of Life Following Coronary Artery Bypass Grafting: A Mixed-Methods Study

INTRODUCTION

Coronary artery bypass grafting (CABG) is an essential surgical management modality for patients with coronary artery disease. Health-related quality of life (HRQoL) has become important because of the significant decrease in the mortality rate associated with CABG. We aimed to explore the factors that affect the quality of life after CABG.

METHODS

This study used a descriptive correlational design to assess the determinants of HRQoL using the 36-item Short Form Health Survey questionnaire (SF-36). Patients who underwent CABG at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, between March 2015 and December 2021 were enrolled in this study. Overall, 275 participants were eligible for our study, of which 84 were found to be valid for analysis. Phone contacts were made directly with the patient after briefly explaining the study. Scores and clinical data were investigated using multivariable linear regression analysis.

RESULTS

Subscales of role limitations due to physical issues had the lowest mean scores, followed by vitality and general health (57.4 ± 44.7; 60.4 ± 25.6; 64.1 ± 22.6), respectively. However, social functioning (78.9 ± 29.0) and pain (75.1 ± 29.9) had the highest scores of all subscales. A history of congestive heart failure (CHF) was independently associated with lower scores for physical role limitations (p = 0.021), vitality (p = 0.001), general health (p< 0.001), and mental health (p = 0.011). Lower mental health scores were also predicted by being a widow (p = 0.030), whereas lower general health scores were predicted by being unemployed (p = 0.001) and having a peripheral vascular disease (PVD) (p = 0.043). Additionally, the development of postoperative complications was an independent predictor of lower physical functioning (p = 0.028) and vitality (p = 0.043). Regarding the number of grafts, cardiopulmonary bypass, and cross-clamp time, no significant impact was found on any of the SF-36 subscales (p> 0.05).

CONCLUSION

The postoperative decline in HRQoL was attributed to comorbidities such as CHF and PVD, postoperative complications including bleeding and wound infection, as well as unemployment and widowed status. Therefore, choosing the appropriate patients for surgery and post-discharge follow-up may enhance HRQoL.

Quality of life in patients undergoing minimally invasive cardiac surgery: a systematic review

Objective

Minimally invasive procedures have been developed to reduce surgical trauma after cardiac surgery. Clinical recovery is the main focus of most research. Still, patient-centred outcomes, such as the quality of life, can provide a more comprehensive understanding of the impact of the surgery on the patient's life. This systematic review aims to deliver a detailed summary of all available research investigating the quality of recovery, assessed with quality of life instruments, in adults undergoing minimally invasive cardiac surgery.

Methods

All randomised trials, cohort studies, and cross-sectional studies assessing the quality of recovery in patients undergoing minimally invasive cardiac surgery compared to conventional cardiac surgery within the last 20 years were included, and a summary was prepared.

Results

The randomised trial observed an overall improved quality of life after both minimally invasive and conventional surgery. The quality of life improvement in the minimally invasive group showed a faster course and evolved to a higher level than the conventional surgery group. These findings align with the results of prospective cohort studies. In the cross-sectional studies, no significant difference in the quality of life was seen except for one that observed a significantly higher quality of life in the minimally invasive group.

Conclusions

This systematic review indicates that patients may benefit from minimally invasive and conventional cardiac surgery, but patients undergoing minimally invasive cardiac surgery may recover sooner and to a greater extent. However, no firm conclusion could be drawn due to the limited available studies. Therefore, randomised controlled trials are needed.

Inspiratory Muscle Training in Patients in the Postoperative Phase of Cardiac Surgery: A Systematic Review and Meta-Analysis

To review the evidence about inspiratory muscle training (IMT) in patients in postoperative of cardiac surgery. We conducted this systematic review used the databases Ovid, LILACS, CINAHL, PubMed, PEDro, and CENTRAL. Randomized clinical trials that addressed IMT after cardiac surgery were selected. The outcomes assessed were maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), tidal volume (TV), peak expiratory flow (PEF), functional capacity (6-minute walk test) and length of hospital stay. The mean difference between groups and the respective 95% confidence interval (CI) were calculated and used to quantify the effect of continuous outcomes. Seven studies were selected. The IMT was superior to the control over MIP 15.77 cmH2O (95% CI, 5.95-25.49), MEP 15.87 cmH2O (95% CI, 1.16-30.58), PEF 40.98 L/min (95% CI, 4.64-77.32), TV 184.75 mL (95% CI, 19.72-349.77), hospital stay -1.25 days (95% CI, -1.77 to -0.72), but without impact on functional capacity 29.93 m (95% CI, -27.59 to 87.45). Based on the results presented, IMT was beneficial as a form of treatment for patients after cardiac surgery.

Does Quality of Life in Survivors of Surgery for Acute Left-Sided Infective Endocarditis Differ from Non-Endocarditis Patients?

Surgery for left-sided infective endocarditis (IE) has been demonstrated to improve patients' survival rates but information about quality of life (QoL) after surgery is scarce. The aim of this study was to assess the postoperative outcomes and QoL after surgery for IE patients compared to patients undergoing cardiac surgery for non-IE indications. Adult patients with definite acute left-sided IE were matched 1:1 to patients who underwent cardiac surgery for non-endocarditic purposes from 2014 to 2019. QoL was assessed using the SF-36 survey at the last follow-up. A total of 105 patients were matched. The IE group had higher rates of preoperative stroke (21% vs. 7.6%, p = 0.005) and higher stages of NYHA class (p < 0.001), EuroSCORE II (12.3 vs. 3.0, p < 0.001) and blood cell count abnormalities (p < 0.001). The IE group had higher incidence of low cardiac output syndrome (13.3% vs. 4.8%, p = 0.029), dialysis (10.5% vs 1.0%, p = 0.007) and prolonged mechanical ventilation (16.2% vs. 2.9%, p = 0.002) after surgery. At the last follow-up, subcomponents of the SF-36 QoL survey were not different between the groups. Patients who underwent cardiac surgery for IE demonstrated a higher risk profile with a higher rate of postoperative complications. Once recovered from the acute phase of the disease, the reported QoL at follow-up was comparable to that of matched cardiac patients operated for non-IE purposes.

Applying Machine Learning to Construct a Model of Risk of Depression in Patients Following Cardiac Surgery with the Use of the SF-12 Survey

BACKGROUND

Depression is a common problem in patients with cardiovascular diseases. Identifying a risk factor model of depression has been postulated. A model of the risk of depression would provide a better understanding of this disorder in this population. We sought to construct a model of the risk factors of depression in patients following cardiac surgery, with the use of machine learning.

METHODS AND MEASURES

Two hundred and seventeen patients (65.4% men; mean age 65.14 years) were asked to complete the short form health survey-12 (SF-12v.2), three months after hospital discharge. Those at risk of depression were identified based on the SF-12 mental component summary (MCS). Centroid class principal component analysis (CCPCA) and the classification and regression tree (CART) were used to design a model.

RESULTS

A risk of depression was identified in 29.03% of patients. The following variables explained 82.53% of the variance in depression risk: vitality, limitation of activities due to emotional problems (role-emotional, RE), New York Heart Association (NYHA) class, and heart failure. Additionally, CART revealed that decreased vitality increased the risk of depression to 45.44% and an RE score > 68.75 increased it to 63.11%. In the group with an RE score < 68.75, the NYHA class increased the risk to 41.85%, and heart failure further increased it to 44.75%.

CONCLUSION

Assessing fatigue and vitality can help health professionals with identifying patients at risk of depression. In addition, assessing functional status and dimensions of fatigue, as well as the impact of emotional state on daily functioning, can help determine effective intervention options.

Benchmark of Intraoperative Activity in Cardiac Surgery: A Comparison between Pre- and Post-Operative Prognostic Models

Objectives: Despite its large diffusion and improvements in safety, the risks of complications after cardiac surgery remain high. Published predictive perioperative scores (EUROSCORE, STS, ACEF) assess risk on preoperative data only, not accounting for the intraopertive period. We propose a double-fold model, including data collected before surgery and data collected at the end of surgery, to evaluate patient risk evolution over time and assess the direct contribution of surgery. Methods: A total of 15,882 cardiac surgery patients from a Margherita-Prosafe cohort study were included in the analysis. Probability of death was estimated using two logistic regression models (preoperative data only vs. post-operative data, also including information at discharge from the operatory theatre), testing calibration and discrimination of each model. Results: Pre-operative and post-operative models were built and demonstrate good discrimination and calibration with AUC = 0.81 and 0.87, respectively. Relative difference in pre- and post-operative mortality in separate centers ranged from −0.36 (95% CI: −0.44–−0.28) to 0.58 (95% CI: 0.46–0.71). The usefulness of this two-fold preoperative model to benchmark medical care in single hospital is exemplified in four cases. Conclusions: Predicted post-operative mortality differs from predicted pre-operative mortality, and the distance between the two models represent the impact of surgery on patient outcomes. A double-fold model can assess the impact of the intra-operative team and the evolution of patient risk over time, and benchmark different hospitals on patients subgroups to promote an improvement in medical care in each center.

Quality of Life and Social Functioning of Patients After Cardiosurgical Interventions

The objective: to study the quality of life (QOL) and social functioning of patients who underwent cardiosurgery intervention (CSI) with the use of artificial circulation (AR) in the postoperative period, to determine and improve the system for further medical, psychological and social rehabilitation. Materials and methods. 700 patients who underwent CSI with the use of AR were treated at the Heart Institute of the Ministry of Health of Ukraine. 86 patients had cerebral infarction (CI), 217 patients with signs of postoperative encephalopathy, and 504 patients with signs of cognitive dysfunction. The level of QOL and social functioning in patients with this pathology was analyzed. Statistical analysis of differences in the quantitative values of indicators was performed using the nonparametric Mann-Whitney test. Results. It was found that patients after CSI had generally low levels of QOL in all fields, namely in the indicators of psychological (emotional) well-being, general perception of life, ability to work, physical well-being, personal realization, selfcare and independence; interpersonal interaction. The presence of ischemic and neurological complications in patients after CSI significantly reduces the QOL indicators in all areas, with differences in the quantitative values of such patients statistically significant (p<0,01) compared to the groups of patients without such complications. The most significant deterioration of QOL is found in patients with cerebral infarction in the postoperative period, slightly less significant – in patients with signs of postoperative encephalopathy, and the smallest changes – in patients with signs of cognitive dysfunction. Conclusions. The main task of modern cardiac surgery is not only to save the patient from death, but also to improve the quality of life (QOL). At the same time, patients after cardiac surgery are at risk of developing ischemic, neurological complications that significantly reduce QOL in all areas of life. That is why it is necessary to take into account the findings of the study in the development of treatment and rehabilitation programs and preventive measures for such patients.

The effectiveness of preoperative education interventions on improving perioperative outcomes of adult patients undergoing cardiac surgery: a systematic review and meta-analysis

BACKGROUND

Cardiac surgeries pose as an emotional experience for patients. Preoperative education is known to positively alter people's perceptions, emotions, and mitigate surgical distress. However, this intervention's effectiveness in improving perioperative outcomes among patients undergoing cardiac surgery lacked rigorous statistical synthesis and remains inconclusive.

AIMS

The aim was to synthesize the effectiveness of preoperative education on improving perioperative outcomes [anxiety, depression, knowledge, pain intensity, pain interference with daily activities, postoperative complications, length of hospitalization, length of intensive care unit (ICU) stay, satisfaction with the intervention and care, and health-related quality of life] among patients undergoing cardiac surgery.

METHODS

This systematic review and meta-analysis conducted a comprehensive search of nine electronic databases (PubMed, EMBASE, Scopus, MEDLINE, CINAHL, Cochrane CENTRAL, Web of Science, PsycINFO, and ERIC) and grey literature for randomized controlled trials examining the preoperative educational interventional effects on patients undergoing cardiac surgery from inception to 31 December 2020. The studies' quality was evaluated using Cochrane Risk-of-Bias Tool 1 (RoB1). Meta-analyses via RevMan 5.4 software synthesized interventional effects.

RESULTS

Twenty-two trials involving 3167 participants were included. Preoperative education had large significant effects on reducing post-intervention preoperative anxiety (P = 0.02), length of ICU stay (P = 0.02), and improving knowledge (P < 0.00001), but small significant effect sizes on lowering postoperative anxiety (P < 0.0001), depression (P = 0.03), and enhancing satisfaction (P = 0.04).

CONCLUSIONS

This review indicates the feasibility of preoperative education in clinical use to enhance health outcomes of patients undergoing cardiac surgery. Future studies need to explore knowledge outcomes in-depth and more innovative technologies in preoperative education delivery.

Dexmedetomidine Use in Intensive Care Unit Sedation and Postoperative Recovery in Elderly Patients Post-Cardiac Surgery (DIRECT)

OBJECTIVE

This study examined recovery, delirium, and neurocognitive outcome in elderly patients receiving dexmedetomidine or propofol sedation after undergoing cardiac surgery.

DESIGN

Open-label randomized trial.

SETTING

Single center.

PARTICIPANTS

A total of 70 patients older than 75 years without English language limitations and Mini Mental State Examination scores >20.

INTERVENTIONS

Patients received either propofol (group P) or dexmedetomidine (group D) postoperatively until normothermic and hemodynamically stable.

MEASUREMENTS AND MAIN RESULTS

Quality of recovery (QoR) was measured by the QoR-40 questionnaire on postoperative day (POD) three. Secondary outcomes were incidence and duration of delirium, time to extubation, length of hospital stay, hospital mortality rate, postoperative quality of life (QoL; measured by SF-36 performed at baseline and six months postoperatively), and neurocognitive disorder (measured by Minnesota Cognitive Acuity Screen [MCAS] performed at baseline, POD5, and six months postoperatively). A total of sixty-seven patients completed the trial. There was no significant difference in QoR-40 scores (95% confidence interval [CI], -7.6081-to-10.9781; p = 1.000), incidence of delirium (group P, 42%; group D, 24%; p = 0.191), mean hospital stay (95% CI, -5.4838-to-1.5444; p = 0.297), mean time to extubation (95% CI, -19.2513-to-7.5561; p = 0.866), or mean duration of delirium (95% CI, -4.3065-to-1.067; p = 0.206) between groups. No patients died in the hospital. There were no significant differences in changes in SF-36 or MCAS scores over time between groups. There was a decline in MCAS score from preoperatively to POD5 in group P (95% CI, -8.95725-to- -2.61775; p = 0.0005), which was greater than that observed in group D.

CONCLUSIONS

The authors' findings demonstrated that the use of dexmedetomidine compared with propofol in elderly patients undergoing cardiac surgery was unlikely to improve QoR/postoperative QoL. Although the study was underpowered to detect secondary outcomes, the results suggested no reductions in delirium, time to extubation, and hospital stay, but a potential decrease in delayed neurocognitive recovery.

Predictors of long-term HRQOL following cardiac surgery: a 5-year follow-up study

Background

The study aimed to evaluate the long-term change of health-related quality of life (HRQOL) and to identify predictors of HRQOL 5 years after cardiac surgery.

Methods

Consecutive adult patients, undergoing elective cardiac surgery were enrolled in the study. HRQOL was measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) questionnaire before and 5-years after cardiac surgery. A multivariate latent change modeling approach was used for data analysis.

Results

210 participants (30.5% female) were reached at 5-year follow-up and included in final data analysis. The study revealed, after controlling for gender effects, a significant long-term positive change, in physical functioning (PF, M_slope = 19.79, p < 0.001), social functioning (SF, M_slope = 17.27, p < 0.001), vitality (VT, M_slope = 6.309, p < 0.001) and mental health (MH, M_slope = 8.40, p < .001) in the total sample. Lower education was associated with an increase in PF (M_slope = 24.09, p < 0.001) and VT (M_slope = 8.39, p < 0.001), more complicated surgery (other than the coronary artery bypass graft (CABG) predicted increase in general health (GH, M_slope = 6.76, p = 0.005). Arrhythmia was a significant predictor for lower pre- and post-operative VT and SF.

Conclusions

Overall HRQOL in our sample improved from baseline to five years postoperatively. Further studies including larger patient groups are needed to confirm these findings.

Predictors of patient-reported health following cardiac surgery

BACKGROUND

Patient-reported health status is one of the most important aspects of cardiovascular outcomes. The aim of this study was to assess patient-reported health and its determinants following cardiac surgery.

METHODS

Cross-sectional study was performed among 128 patients (mean age: 66.02; 35.9% women). Three months after surgery patients filled in The Short Form 12 Health Survey (SF-12) and Brief-Illness Perception Questionnaire (B-IPQ). Patient-reported health was assessed using SF-12 General Health component.

RESULTS

The mean General Health score was 47.34 (SD=20.94). General Health was significantly positively correlated with SF-12 Physical and Mental Component Summary (P<0.01). Significant negative correlations were noted between General Health and European System for Cardiac Operative Risk Factor (EuroSCORE) (P=0.012) and Body Mass Index (BMI) (P=0.026). Higher scores on B-IPQ Consequences, Timeline, Identity, Emotional Response (P<0.01) and Concern (P=0.03) were related to worse General Health. Higher perceived effectiveness of surgery (P<0.01) and Treatment control (P=0.003) were associated with higher General Health score. More negative illness perception was significantly related to lower General Health (P<0.01). No significant associations between General Health and mode and weight of the procedure, myocardial infarction, previous percutaneous coronary intervention, New York Heart Association (NYHA) and Canadian Cardiovascular Society (CCS) class and postsurgical complications were noted. Structural equation modeling (SEM) revealed that illness perception domains, BMI and EuroSCORE are the main determinants of General Health.

CONCLUSIONS

Modifiable factors, especially illness perception are important determinants of patient-reported health after cardiac surgery. Evaluation of illness perception seems vital since it may lead to address patients' concerns and improve outcomes.

The trade-off between costs and outcome after cardiac surgery. Evidence from an Italian administrative registry

Effective resource allocation policies relating to the long-term effects of complex surgical procedures require accurate prediction of the likelihood of future hospitalization. By approximating clinical conditions with administrative data and controlling for complex case-mix scenarios, we provide evidence of a trade-off between costs and outcome in cardiac surgery. We modelled administrative data to account for clinical conditions in a population of patients admitted for cardiac surgery and their readmissions for complications. Costs were calculated at first admission, the outcome variable was defined as time to readmission within six months post-discharge. Risk factors for readmission were defined as comorbidities and postoperative complications, derived by clinical judgement from the International Classification of Diseases. We predicted health outcome as a function of costs and other patient- and hospital-level features using a two-stage residual inclusion estimation method to tackle endogenous relationships applied to Cox proportional hazard models. We confirmed the trade-off and negative association between costs and hazard of readmission when controlling for all complex risk factors. Accurate matching of standard codes for diseases and procedures with clinical conditions may be a reliable methodology to assess time to readmissions and costs on a large population scale.

Determinants of non-recovery in physical health-related quality of life one year after cardiac surgery: a prospective single Centre observational study

BACKGROUND

Recent studies show that substantial percentage of patients experienced worsening of health related quality of life (HRQoL) 1 year after cardiac surgery. The aim of this study is to identify risk factors that interfere with improvement of HRQoL.

METHODS

From December 2015 till July 2017 a prospective single centre observational study was carried out in 1920 patients participated who underwent non-salvage cardiac surgery. All patients were requested to complete a Short Form 36 (SF-36) questionnaire before and 1 year after surgery. Primary aim of the study was to identify risk factors for non-recovery in the physical domain of the SF-36 in all cardiac surgery patients. Secondary aim was to identify identical risk factors in patients with isolated coronary artery bypass grafting.

RESULTS

After cardiac surgery, the questionnaires for physical and mental health were completed by respectively 803 and 807 patients. Median age was 69[62-75] years, and 77% was male. In comparison to the preoperative status, 176 patients (21.9%) did not display an improvement in the SF-36 physical domain score 1 year after cardiac surgery. In a multivariate analysis independent risk factors for non-recovery in the SF-36 physical domain were baseline SF36 physical domain score (OR 0.954[0.942-0.965], P < 0.001), diabetes (OR 0.437 [0.265-0.720], P 0.001), female sex (OR 0.492 [0.307-0.789], P 0.003), post-operative infection (OR 0.240 [0.109-0.525], P < 0.001) and PCI within 1 year (OR 0.113 [0.036-0.349], P < 0.001) For isolated CABG, 23.2% of patients did not display an improvement in the physical domain score and risk factors appeared to be identical.

CONCLUSIONS

Twenty two percent of all cardiac surgery patients did not show an improvement in the physical domain score of the HRQoL between the preoperative period and 1 year after surgery. Independent risk factors for non-recovery after cardiac surgery were baseline SF-36 physical domain score, diabetes, female sex, any postoperative infection and the need for PCI in the first year. Further research is needed to tailor the patient selection procedure prior to surgery and potentially modify risk factors in the perioperative process.

Clinical, Surgical, and Sociopsychological Factors and Depression After Cardiothoracic Surgery

BACKGROUND

Depression is highly prevalent in cardiac surgical patients and is associated with mortality. The objectives of the study were to evaluate depression scores longitudinally pre- and postoperatively and to examine the association between postoperative depression scores and clinical, surgical, and sociopsychological factors.

METHODS

Depression scores were assessed using the Center for Epidemiological Study of Depression (CES-D) in 100 cardiac surgical patients who underwent cardiac surgery preoperatively, during hospitalization, and at 2 and 6 week after discharge. Clinical, surgical, and sociopsychological predictors of depression scores were recorded.

RESULTS

The average depression scores significantly increased from preoperative levels (14.9 ± 1.07) to during hospitalization (21.5 ± 1.05) and decreased at both 2 weeks (15.8 ± 1.07) and 6 weeks after discharge (14.0 ± 1.06), as compared with scores during hospitalization (P < .001). The percentage of patients who scored CES-D > 16 increased significantly from preoperative (39%) to hospitalization (71%) and decreased gradually at 2 weeks (45%) and 6 weeks (37%) after discharge (P < .001). Significant predictors of high postoperative CES-D scores were female gender, ejection fraction < 50%, and high preoperative CES-D scores.

CONCLUSIONS

High depression scores after cardiac surgery suggest that perioperative screening and management of depression after surgery are necessary and may improve outcomes of these patients who are at high risk for depression. Further understanding of the factors that contribute to high depression scores is required to facilitate clinical intervention.

The impact of surgical aortic valve replacement on quality of life-a multicenter study

OBJECTIVES

To explore the effect of surgical aortic valve replacement on quality of life and the variance with age, particularly in patients at risk of deterioration.

METHODS

In an observational, multicenter, cohort study of routinely collected health data, patients undergoing and electively operated between January 2011 and January 2015 with pre- and postoperative quality of life data were included. Patients were classified into 3 age groups: <65, 65-79, and ≥80 years. Quality of life was measured at baseline and at 1-year follow-up using the Short-Form Health Survey-12 or SF-36. We defined a >5-point difference as a minimal clinically important difference. Multivariable linear regression analysis, with adjustment for confounders, was used to evaluate the association between age and quality of life.

RESULTS

In 899 patients, mean physical health increased from 55 to 66 and mental health from 60 to 66. A minimal clinically important decreased physical health was observed in 12% of patients aged <65 years, 16% of patients aged 65-79 years, and 22% of patients aged ≥80 years (P = .023). A decreased mental health was observed in 15% of patients aged <65 years, 22% of patients aged 65-79 years, and 24% aged ≥80 years (P = .030). Older age and a greater physical and mental score at baseline were associated with a decreased physical and mental quality of life (P < .001).

CONCLUSIONS

Patients surviving surgical aortic valve replacement on average improve in physical and mental quality of life; nonetheless, with increasing age patients are at higher risk of experiencing a deterioration.

Long-term survival and quality of life in Jehovah's witnesses after cardiac surgery: a case control study

Background

We previously analyzed morbidity and mortality in Jehovah’s Witnesses patients after cardiac surgery compared to control population patients. Patients who were Jehovah’s Witnesses were operated in accordance with their philosophical convictions and in respect of their refusal of transfusions. We propose to assess long-term survival and quality of life in the patients of this preliminary study.

Methods

We contacted 31 adult Jehovah’s Witnesses patients who underwent heart surgery at the Brugmann hospital between 1991 and 2012 and compared them to a control population of 62 patients that had no transfusion restriction, and matched them for sex, age at the time of intervention and the type of surgery performed. We compared long-term quality of life in both populations through the MacNew software, a validated instrument to assess quality of life of patients with cardiovascular disease. The long-term survival of patients was analyzed by Kaplan Meier curves.

Results

Long-term quality of life and survival do not appear different between the two groups. Patient evaluation by MacNew software shows comparable physical (p = 0.54), emotional (p = 0.12), social (p = 0.21) and global (p = 0.25) scores between the two populations. The analysis of the actuarial survival curves shows no differences in terms of long-term survival of these patients (p = 0.37).

Conclusions

Cardiac surgery in Jehovah’s Witnesses can be performed with identical long-term quality of life and survival compared to surgery without blood transfusion restriction, if one follows rigorous blood conserving strategies.
