Comparison of the health related quality of life of patients following mitral valve surgical procedures in the 6-months follow-up: a prospective study

Depressive symptoms, perceived control and quality of life among patients undergoing coronary artery bypass graft: a prospective cohort study

BACKGROUND

Coronary artery bypass graft surgery (CABG) is an intervention directed toward improving the Quality of Life (QoL) for patients with coronary artery disease. Depression can affect QoL negatively among this population. Perceived control (PC) decreased the effect of anxiety on QoL, however, this effect has not been well-studies regarding depression. Therefore, the purpose of this study was to check the effect of depression on QoL among CABG patients and to determine if preoperative PC moderates this effect.

METHODS

This was a prospective observational cohort study conducted on a consecutive sample of 200 patients from three hospitals in Amman, Jordan. Depression Anxiety and Stress Scale, Short-Form Health Survey-36, and Arabic version of the Control Attitude Scale-Revised were used to measure depressive symptoms, QoL and PC respectively. Data were analyzed using t test and step wise multiple regression followed by simple slope analysis.

RESULTS

Postoperative Physical Component Summary (PCS) was better than preoperative PCS (mean ± SD: 38.2 ± 9.4 vs. 36.6 ± 9.5, P < 0.001). Postoperative Mental Component Summary (MCS) was better than preoperative MCS (mean ± SD: 44.3 ± 11.5 vs. 41.4 ± 11.4, P < 0.001). Preoperative depression was higher than postoperative depression; (mean ± SD: 12.8 ± 6.8 vs.11.1 ± 6.7, P < 0.01). Simple slope analysis was significant (simple slope = 0.41, t = 6.1, P < 0.001), indicating the moderating effect of PC.

CONCLUSION

Patients undergoing CABG surgery had poor QoL and high levels of depression. Perceived control moderated this relationship and improve QoL. Assessing depression levels and implantation of interventions to enhance perceived control levels prior to operation might improve QoL.

Symptoms, Hope, Self-Management Behaviors, and Quality of Life Among Chinese Preoperative Patient With Symptomatic Valvular Heart Diseases

Introduction: More than 42 million people are estimated to suffer from valvular heart disease (VHD) worldwide with a prevalence of 5.3% to 7.7% in the Chinese adult population. The purpose of this study was to examine the associations between symptoms, hope, self-management behaviors, and quality of life (QOL) for preoperative patients with symptomatic VHD in a rural area of China. Method: This was a descriptive comparative study that took place in Nanning, China, between January 2015 and March 2016. The sample was 128 preoperative patients with symptomatic VHD. Data were collected using the Symptom Distress Questionnaire, Herth Hope Index, Self-Management Scale, and Minnesota Living with Heart Failure Questionnaire. Results: Data from 122 patients were included in the final analysis. Mean scores of hope, self-management, and QOL were 36.71, 55.27, and 55.56. Worse total scores of symptom severity (r = 0.57 to 0.69, p < .001) and self-management behaviors (r = -0.22 to -0.25, p < .05) were associated with poorer QOL. Fatigue, loss of appetite, and self-management behaviors explained 49.90% variance of QOL (p < .001). Discussion: Fatigue, loss of appetite, and self-management influenced QOL of patients with symptomatic VHD. Interventions aimed at strengthening self-management and relieving symptoms should be tailored for patients with symptomatic VHD base on their traditional animist belief and food culture in rural areas of China such as the Zhuang Autonomous Region.

Health-related quality of life of patients after mechanical valve replacement surgery: an integrative review

BACKGROUND

Heart valve replacement surgery is undertaken to improve cardiac function and health-related quality of life (HRQoL). Mechanical valves are typically used for younger people (aged <65 years). Implantation of these valves comes with life-long health self-management requirements which potentially impact on HRQoL.

AIMS

The purpose of this study was to identify the short and long-term impact on HRQoL after mechanical valve replacement surgery.

METHODS

Multiple electronic databases were searched for peer-reviewed studies published between 2000-2013, which focused on patients who had mechanical valve replacement, aged <65 years, and used a valid measure of HRQoL.

RESULTS

Eight papers were included, all of which used the Short-Form 36 Health Survey (SF-36). Preoperatively, HRQoL was impaired, particularly in the SF-36 health domains of role-physical, physical-functioning, vitality and role-emotional. Postoperatively, most people had positive and sustained HRQoL improvement. In the early postoperative period all data showed significant improvement in at least four of eight health domains (physical function, role-physical, vitality, social function). Two-thirds of people also had significant improvement in an additional two health domains (general and mental-health). Whilst most people sustained HRQoL over time, one-third of younger adults (age <24 years) showed impairment in three domains (physical-function, mental-health and general-health).

CONCLUSIONS

Mechanical valve replacement surgery results in important and sustained improvements in HRQoL. Future research should include investigation of HRQoL outcomes after mechanical valve replacement for specific groups such as younger adults and people in developing countries, and include evaluations of the potential impact of valve-specific factors and health self-management requirements.
