“…The patients are informed of the evaluation results in the early postoperative period, so the difference between the actual result and the originally anticipated distance can be compared. [ 32 ] Clinicians will be able to observe whether the walked distance subsequent to surgery can reach anticipated levels and implement a more intensive and tailored rehabilitation program for patients with a poor prognosis.…”

The 6-minute walk test (6MWT) has been applied to assess postsurgical recovery in cardiac populations. This study mainly investigated whether the 6MWT could serve as an indicator for physical functioning in patients undergoing cardiac surgery.Participants completed the 6MWT and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) at baseline, discharge, and 3 months postoperatively, in order to analyze the construct validity and responsiveness of the 6MWT. The participants in this study were 125 patients (92 males and 33 females) with an average age of 65.1 ± 11.1 years. The mean 6MWT was 308.9 ± 77.3 m in the preoperative phase, decreased to 277.3 ± 85.7 m at discharge, and returned to 378.1 ± 95.2 m at 3-month follow-up. The results showed that the 6-minute walk distances at baseline and at 3-month follow-up were moderately to highly correlated with the physical functioning subscale of the SF-36 (rs = .44 and .54, respectively) and had weak correlation with the nonphysical functioning subscales. The recovery level of physical functioning is meaningfully associated with the 6MWT change from baseline to discharge and from baseline to 3-month follow-up. Patients with higher New York Heart Association (NYHA) Functional Classification levels had lower 6MWT. Additionally, the 6MWT was sensitive to change during the perioperative period (effect sizes from −0.51 to 1.72).The supporting evidence includes the construct validity and responsiveness of the 6MWT. This study supports the feasibility of the 6MWT as an evaluation tool of physical functioning for assessment of postcardiac surgical recovery.

“…8–10 The prognostic role of 6MWT in terms of morbidity and mortality has been evaluated especially in patients with pulmonary arterial hypertension 11 and in HF populations 12,13 as will be discussed further below. Furthermore, the test has been indicated before and after treatment to assess the response to various medical interventions in many patient populations 14 including HF 15 but also to guide cardiac rehabilitation.…”

Reduced functional ability and exercise tolerance in patients with heart failure (HF) are associated with poor quality of life and a worse prognosis. The 6-minute walking test (6MWT) is a widely available and well-tolerated test for the assessment of the functional capacity of patients with HF. Although the cardiopulmonary exercise test (a maximal exercise test) remains the gold standard for the evaluation of exercise capacity in patients with HF, the 6MWT (submaximal exercise test) may provide reliable information about the patient’s daily activity. The current review summarizes the value of 6MWT in patients with HF and identifies its usefulness and limitations in everyday clinical practice in populations of HF. We aimed to investigate potential associations of 6MWD with other measures of functional status and determinants of 6MWD in patients with HF as well as to review its prognostic role and changes to various interventions in these patients.

“…15 Another study that evaluated how the prognostic value of 6MWT after heart valve surgery found a value of 6MWT <215 meters associated with the combined incidence of rehospitalization and mortality (p = 0.003) after 18 months of follow-up. 11 In this study, Based on results of multivariate analysis using the backward stepwise method, the value of Six Minute Walk Test (6MWT) <250 meters will increase the risk of death and rehospitalization 3 months after CABG by 16.74 times greater and has a good prognostic value for combined incidence of death and rehospitalization 3 months after CABG. In the previous study, a value of 6MWT <240 meters was also obtained as a strong predictor variable for rehospitalization and mortality with an RR value of 4.25 (95% CI: 1.646 to 10.962) and p = 0.003 in the follow-up 6 months after CABG so that it can be concluded that patients with Results 6MWT less than 240 meters had a 4.25 times greater risk of hospital rehospitalization and death compared with patients who traveled more than 240 meters.…”

“…They observed that an inability to walk more than 215 m identified patients with a higher risk of cardiovascular death or hospitalization. 11 based on a study involving 882 post-CABG patients alone, found that the 6MWT after surgery predicted 5-year survival in elderly patients (≥ 65 years). 12 The aim of this study was to investigatethe relationship between the distance of 6 minute walk test before discharge with re-hospitalization and mortality rate in post coronary artery bypass surgery patients and the ability of 6MWT in predicting the incidence of death and rehospitalization within 3 months of follow-up after CABG surgery.…”

Background: Patients underwent Coronary Artery Bypass Surgery are at risk of developing post-operative complications that affect length of stay, re-hospitalization and increase in mortality rate. Impaired functional capacity is associated with poor outcomes in patients after CABG. The Six Minute Walk Test (6MWT) is generally used to evaluate functional capacity before cardiac rehabilitation and to prescribe the intensity of exercise training. The six minute walk test (6MWT) is a simple test and has been used in heart failure patients to assess exercise tolerance, the effects of therapy and prognosis. This study is to investigate the relationship between the distance of 6MWTwith re- hospitalization and mortality rate in post coronary artery bypass surgery patients.Method: This is a retrospective cohort study conducted at Cardiac Centre of Adam Malik Hospital. Subjects of the study consists of 104 patients underwent coronary bypass surgery between January 2019 until February 2020. 6MWT is performed before the patient discharge. Rates of re-hospitalisation and mortality were observed during 3 months of follow-up. The distance walk during 6MWT was compare to rate of rehospitalization and cardiac mortality. Result: Total of 104 patients (91 males, mean age 57,4±5,7 years). Six patients died (5,8%) of cardiovascular cause and 18 (17,3%) were rehospitalized. Significant relationship was found between the distance of 6MWT and incidence of mortality and re-hospitalization (p <0.001). Patients with 6MWT <250 meters had a higher risk of re-hospital compared to those with 6MWT >250 meters with RR 16.74 (95% CI: 2.53-110.78) and p = 0.008. Conclusion: The six minute walk test (6MWT) is a predictor of re-hospitalization in patients post CABG. Patients who walked in shorter distance group <250 meters would increase risk of re-hospitalization rate 16.74 greater than patients with distances >250 meters.
