Quality of Life in Patients of Different Age Groups before and after Coronary Artery By-Pass Surgery

The impact of socio-demographic factors on health-related quality of life after coronary artery bypass surgery

OBJECTIVES

To achieve a beneficial impact on long-term outcome after coronary artery bypass grafting (CABG), the goal of the present study was the early identification of patients at risk of impaired postoperative health-related quality of life (HRQoL), particularly evaluating the significance of socio-demographic variables.

METHODS

In this prospective, single-centre cohort study of patients having an isolated CABG (January 2004-December 2014), preoperative socio-demographic (preSOC) and preoperative medical variables as well as 6-month follow-up data including the Nottingham Health Profile were analysed in 3,237 patients.

RESULTS

All preSOC (gender, age, marriage and employment) and follow-up (chest pain, dyspnoea) variables proved to have significant influence on HRQoL (P < 0.001), male patients below 60 years being particularly impaired. The effects of marriage and employment on HRQoL are modulated by age and gender. The significance of the predictors of reduced HRQoL differs between the 6 Nottingham Health Profile domains. Multivariable regression analyses revealed explained proportions of variance amounting to 7% for preSOC and 4% for preoperative medical variables.

CONCLUSIONS

The identification of patients at risk of impaired postoperative HRQoL is decisive for providing additional support. This study reveals that the assessment of 4 preoperative socio-demographic characteristics (age, gender, marriage, employment) is more predictive of HRQoL after CABG than are multiple medical variables.

Quality of life in people with coronary artery disease: translation and cross-cultural adaptation of a questionnaire

OBJECTIVE

to carry out translation, cross-cultural adaptation to Portuguese and assess the reliability of the four versions of the Coronary Revascularization Outcome Questionnaire - adapted.

METHODS

a methodological study of translation and cross-cultural adaptation into Portuguese, as proposed by Beaton et al., and reliability analysis, by calculating Cronbach's alpha coefficient and item-total correlation of the four versions of the Coronary Revascularization Outcome Questionnaire - adapted.

RESULTS

the adaptations made facilitated the understanding of the items. All domains had Cronbach's alpha above 0.70, except two in the post-percutaneous coronary intervention version and two in the post-myocardial surgical revascularization version. All items had item-total correlation values greater than 0.20, except two in the post-percutaneous coronary intervention version, one in the pre-coronary intervention version and six in the post-myocardial surgical revascularization version.

CONCLUSION

the cross-cultural adaptation to Portuguese was considered satisfactory. Pre-procedure versions were considered reliable, while the post-procedures require other psychometric analyses.

Neurological outcome after minimally invasive coronary artery bypass surgery (NOMICS): An observational prospective cohort study

Background/Objectives

Endoscopic coronary artery bypass grafting (Endo-CABG) is a minimally invasive CABG procedure with retrograde arterial perfusion. The main objective of this study is to assess neurocognitive outcome after Endo-CABG.

Methods/Design

In this prospective observational cohort study, patients were categorised into: Endo-CABG (n = 60), a comparative Percutaneous Coronary Intervention (PCI) group (n = 60) and a healthy volunteer group (n = 60). A clinical neurological examination was performed both pre- and postoperatively, delirium was assessed postoperatively. A battery of 6 neurocognitive tests, Quality of life (QoL) and the level of depressive feelings were measured at baseline and after 3 months. Patient Satisfaction after Endo-CABG was assessed at 3-month follow-up. Primary endpoints were incidence of postoperative cognitive dysfunction (POCD), stroke and delirium after Endo-CABG. Secondary endpoints were QOL, patient satisfaction and the incidence of depressive feelings after Endo-CABG.

Results

In total, 1 patient after Endo-CABG (1.72%) and 1 patient after PCI (1.67%) suffered from stroke during the 3-month follow-up. POCD in a patient is defined as a Reliable Change Index ≤-1.645 or Z-score ≤-1.645 in at least two tests, and was found in respectively 5 and 6 patients 3 months after Endo-CABG and PCI. Total incidence of POCD/stroke was not different (PCI: n= 7 [15.9%]; Endo-CABG: n= 6 [13.0%], p = 0.732). ICU delirium after Endo-CABG was found in 5 (8.6%) patients. QoL increased significantly three months after Endo-CABG and was comparable with QoL level after PCI and in the control group. Patient satisfaction after Endo-CABG and PCI was comparable. At follow-up, the level of depressive feelings was decreased in all groups.

Conclusions

The incidence of poor neurocognitive outcome, including stroke, POCD and postoperative ICU delirium until three months after Endo-CABG is low and comparable with PCI.

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.

Prior percutaneous coronary intervention is associated with low health-related quality of life after coronary artery bypass graft

The success of a coronary artery bypass graft surgery has been shown to be related to health-related quality of life, and being able to predict this is extremely useful. We investigate the associations between health-related quality of life and sociodemographic and clinical characteristics, and examine the impact of prior percutaneous coronary interventions on health-related quality of life in Palestinian patients undergoing a coronary artery bypass graft for the first time. A cross-sectional study was conducted on a convenience sample of 119 Palestinian patients. The Short Form-36 Health Survey was applied 1 year after the coronary artery bypass graft surgery. An analysis of variance shows that as age increases, health-related quality of life decreases. In contrast, the higher the level of education, job security, and salary, the higher the health-related quality of life. Patients who had undergone prior percutaneous endovascular interventions had a worse health-related quality of life than those who had not. In conclusion, a history of prior percutaneous endovascular interventions in addition to sociodemographic factors should be considered by nursing staff so that they can deliver high-quality patient care.

Assessment of the Quality of Life in Patients before and after Coronary Artery Bypass Grafting (CABG): A Prospective Study

The aim of this study was to examine the quality of life and to report on the utility and QALY measures in patients before and after coronary artery bypass grafting (CABG); to investigate whether the SF-12 is comparable with the SF-36 for measuring health-related quality of life of patients with CABG; and to determine the impact of individual predictors on poor quality of life assessment after rehabilitation. This prospective study was conducted between January 2017 and December 2018 at the University Hospital Center Osijek, at three time points: pre-operation, 1 month after surgery, and after rehabilitation. The study was conducted with the SF-36 and SF-12 health questionnaires on 47 participants. After rehabilitation, there was a significant improvement in all domains of quality of life. The highest score was given to the change in pain (BP); mean scores were 63.8 (95% CI 56.9 to 70.6) (p = 0.001). The lowest grade (the lowest quality) after rehabilitation was in the domain of limitations due to physical difficulties (RP); arithmetic mean was 48.5 (95% CI 41 to 55.9) (p < 0.001). Quality-adjusted life-year was 0.41 (95% CI 0.38–0.44) after the CABG. The results of this study show that patients with coronary heart disease have poor quality of life before surgery. One month after the surgery, the quality of life improved, but was still inadequate. One year after surgery, satisfactory results were obtained in almost all subscales. The SF-36, SF-12, and its components, can be used effectively in patients with CABG. Age, gender, lifestyle, and risk factors in our sample of participants are not predictors of poor quality of life assessment after rehabilitation.

Functional status and life satisfaction of patients with stable angina pectoris in Austria

OBJECTIVES

Although substantial progress in the treatment of stable angina pectoris (sAP) has been made, little is known about the functional status and quality of life (QoL) of patients in different healthcare systems.

DESIGN AND METHODS

We undertook a survey using the Seattle Angina Questionnaire (SAQ) (five domains scored form 0-worst assessment to 100-best assessment) to assess symptoms, QoL (including limitation of activities), demographics, geographic distribution and individual disease data in patients with stable coronary artery disease in Austrian cardiology practices.

RESULTS

A total of 660 patients with sAP with a mean age of 69.2 years were included. SAQ scores were 67.5±24.4 for physical limitation, 65.5±26.6 for angina stability, 79.3±23.2 for angina frequency, 86.3±16.2 for treatment satisfaction and 63.7±24.2 for overall QoL. Multiple regression identified male gender, but also female gender, Eastern Austrian residence and high body mass index as predictive factors for SAQ scoring. A total of 35.6% of the patients reported at least one desirable activity that was limited through AP symptoms.

CONCLUSIONS

Activity and QoL assessments are in accordance with published literature: The number and the diversity of desired activities indicate the need to focus on patient's individual activity level to improve symptom management.

Major adverse cardiac and cerebrovascular event and patients' quality of life after endoscopic vein harvesting as compared with open vein harvest (MAQEH): a pilot study

Background

This is a prospective, comparative, pilot and follow-up (2-year postoperatively) study in patients undergoing coronary artery bypass graft surgery where the long saphenous vein was harvested either by the endoscopic vein harvest (EVH) technique or open vein harvest (OVH) technique. Quality of life (QOL) and major adverse cardiac and cerebrovascular events (MACCE) were assessed.

Methods

Alive patients who were initially part of a pilot study when EVH was introduced in our institution were included (n=48 EVH, n=49 OVH). Patients were sent a QOL questionnaire (SF12v2; 12-item medical outcomes study short form health survey version 2.0), and their cardiologist and general practitioner were contacted to assess MACCE.

Results

Median follow-up was 32 and 33 months, respectively. Three patients died (2 EVH, 1 OVH). Of the remaining 97 patients who were sent a questionnaire, 76% patients returned the form. More patients from the EVH group returned the QOL questionnaire (82% vs 71%). Time taken to return to normal daily activities was much shorter in EVH (median 6 (2–30) weeks) compared with OVH (median 9 (2–50) weeks) (P<0.05). QOL questionnaire revealed significant difference in physical score at follow-up: 45.3 (10.2) for EVH group and 40.7 (11.0) for OVH group (P<0.05). There was no difference in mental scores (46.9 (10.5) vs 49.2 (9.1), P=0.4). There were no significant differences in MACCEs including death between the two groups (12.2% vs 13.9%, P=0.5).

Conclusion

EVH patients returned to normal daily activities faster than OVH patients and experienced better physical QOL even after 2 years postoperatively with no increase in MACCE during follow-up.

The quality of life of patients developed delirium after coronary artery bypass grafting is determined by cognitive function after discharge: A cross-sectional study

AIMS

Postoperative delirium (POD) and declined cognitive function were common in patients (especially elderly patients) who underwent coronary artery bypass grafting (CABG), which may affect quality of life (QoL). The aim of this study was to determine the relationships among age, POD, declined cognitive function, and QoL in patients who underwent CABG.

METHODS

Consecutive patients who underwent first time elective CABG and assessed for POD using Confusion Assessment Method for intensive care unit for 5 postoperative days from November 2013 to March 2015 were recruited. A cross-sectional study was conducted during April 2015 to assess their cognitive function and QoL, using the Telephone Interview for Cognitive Status Scale and Medical Outcomes Study 36-Item Short Form Health Survey. The relationships among age, POD, declined cognitive function, and QoL were tested using path analysis.

RESULTS

Declined cognitive function was associated with poorer QoL. POD was associated with declined cognitive function but was not associated with poorer QoL. Ageing was not associated with QoL but was associated with POD and declined cognitive function.

CONCLUSION

The QoL of patients developed delirium after CABG is determined by cognitive function after discharge. Necessary strategies should be implemented to prevent POD and declined cognitive function, especially in elderly patients.

Impact of post-hospital cardiac rehabilitation on the quality of life of patients after surgical treatment for coronary artery disease

INTRODUCTION

The quality of life of cardiovascular patients is worse than that of healthy individuals. Pain, dyspnea, and fatigue impair daily activities, which in turn leads to decreased life satisfaction and emotional deterioration. The objective of comprehensive treatment, including early rehabilitation, is to reduce the risk of complications, progression, and recurrence of the disease, as well as to restore, maintain, or improve all aspects of the patient's quality of life to the greatest extent possible.

AIM

To assess the quality of life of patients who underwent surgical treatment for coronary artery disease and completed the second phase of cardiac rehabilitation.

MATERIAL AND METHODS

The study enrolled 100 patients undergoing early cardiac rehabilitation in stationary conditions after coronary artery bypass grafting. The group included 21 women and 79 men; their age ranged from 40 to 75 years. The study employed a questionnaire of our own design.

RESULTS

Post-hospital cardiac rehabilitation resulted in quality of life improvements, especially with regard to psychological aspects, reducing the occurrence of anxiety from 44% to 21%. In addition, the rehabilitation program reduced the occurrence of subjective ailments such as chest pain (from 68% to 10%), fatigue (from 40% to 33%), and dyspnea (from 50% to 12%).

CONCLUSIONS

Despite the achievement of quality of life improvements among patients after surgery coronary artery by-pass grafting and early cardiac rehabilitation, the result is not fully satisfactory. Systematic treatment and education should be continued to further improve the health of patients.

Impact of marital status and comorbid disorders on health-related quality of life after cardiac surgery

PURPOSE

To explore associations between HRQL, marital status, and comorbid disorders in men and women following cardiac surgery.

METHOD

A secondary analysis was completed using data from a randomized controlled trial in which 416 individuals (23% women) scheduled for elective coronary artery bypass graft and/or valve surgery were recruited between March 2012 and September 2013. HRQL was assessed using the Health State Descriptive System (15D) preoperatively, then at 2 weeks, and at 3, 6, and 12 months following cardiac surgery. Linear mixed model analyses were performed to explore associations between HRQL, social support, and comorbid disorders.

RESULTS

The overall 15D scores for the total sample improved significantly from 2 weeks to 3 months post surgery, with only a gradual change observed from 3 to 12 months. Thirty percent (n = 92) of the total sample reported a lower 15D total score at 12 months compared to preoperative status, of whom 78% (n = 71) had a negative minimum important differences (MID), indicating a worse HRQL status. When adjusted for age and marital status, women had statistically significant lower 15D total scores compared to men at 3, 6, and 12 months post surgery. Compared to pre-surgery, improvement was demonstrated in 4 out of 15 dimensions of HRQL for women, and in 6 out of 15 dimensions for men at 12 months post surgery. Both men and women associated back/neck problems, depression, and persistent pain intensity with lower HRQL; for women, not living with a partner/spouse was associated with lower HRQL up to 12 months.

CONCLUSION

Women experienced decreased HRQL and a slower first-year recovery following cardiac surgery compared to men. This study demonstrates a need for follow-up and support to help women manage their symptoms and improve their function within the first year after cardiac surgery. This was particularly pronounced for those women living alone.
