Factors associated with health indicators in patients undergoing coronary artery bypass surgery

Factors influencing return to work at one year after coronary bypass graft surgery: results of the PERISCOP study

PURPOSE

The aim of this study was to evaluate the predictive factors of return to work after coronary bypass graft surgery, for the subgroup of professionally active patients aged less than 60 years included in the PERISCOP study.

METHODS

In the principal, prospective, multicentre study, 2065 patients were evaluated 20+/-10 days after surgery by exercise testing, echocardiogram and 24-h ambulatory ECG monitoring. A questionnaire was completed one year after surgery. We studied a subgroup of this population, consisting of 530 patients previously defined (94.5% men; mean age: 50.5+/-5.8 years).

RESULTS

One year after surgery, five of these patients had died and 21 were lost to follow-up. Among the remaining patients, 340 patients (67.5%) had returned to work. Forty patients (7.9%) had retired, 45 (8.9%) were on sick leave, 22 (4.4%) were unemployed, 49 (9.7%) returned to work after the deadline of 12 months, eight (1.6%) had given insufficient information on return to work. In multivariate analysis, the independent predictors of a failure to return to work were age >51 years [OR: 0.39 (95% CI: 0.25-0.59)], being a manual worker [OR: 0.49 (95% CI: 0.31-0.79)], being from South East France [(OR: 0.42 (95% CI: 0.23-0.74)], presence of angina [OR: 0.40 (95% CI: 0.20-0.82)], dyspnoea [(OR: 0.46 (95% CI: 0.28-0.77)] and a duration of exercise <420 s [(OR: 0.50 (95% CI: 0.33-0.76)].

CONCLUSIONS

Return to work after coronary bypass graft surgery is observed in 67.5% of cases and depends essentially on socio-professional factors and residual symptoms. A regional effect was also observed, which requires further study.

Return to work after coronary artery bypass in patients aged under 50 years

Background: This study was designed to identify factors associated with return to work and quality of life in patients undergoing primary coronary artery bypass at age <50 years.

Methods: 172 patients <50-years old underwent primary coronary artery bypass between January 2000 and December 2006. Predictors of return to work were analysed from variables in a prospectively collected database and on follow-up by the SF-36 questionnaire in 129 (75%) patients.

Results: 136 (79%) patients were working prior to surgery. The educational level was: primary 14.5%, secondary 47%, trade 22%, tertiary 13%, and postgraduate 3%. Type of occupation was blue collar 51%, white collar 41%, pensioner 27%, and unspecfied 8%. The mean follow-up was 86.4 ± 23.4 months. One hundred and twenty-six (69%) patients attended cardiac rehabilitation. Forty (23%) patients experienced recurrence of symptoms; 11 (6%) required reintervention. One hundred and twenty-seven (93%) patients returned to work postoperatively. Univariate predictors of return to work were male sex, blue-collar work, and working prior to surgery. Independent predictors of return to work were working prior to surgery and blue-collar work. Patients who returned to work had significantly higher scores in all 8 domains on the SF36-Questionnaire compared to those who did not return to work.

Conclusions: Preoperative employment and blue collar occupation were associated with a higher rate of return to work after coronary artery bypass in patients of working age. Patients who returned to work had significantly better measured quality of life than those who did not.

Return to work after coronary artery bypass surgery. A 10-year follow-up study

OBJECTIVES

To establish which factors influence patients' return to work and how well they remain at work after coronary artery bypass grafting (CABG).

DESIGN

Five hundred and sixty nine consecutive CABG patients aged less than 65 years were followed for 10 years. Data were collected from patient records and by questionnaires supplemented with information from Finnish national archives.

RESULTS

Multivariate analysis showed the best predictors for return to work to be younger age, preoperative working, as well as absence of diabetes or perioperative cardiac damage. Almost half of the patients aged less than 60 and preoperatively not retired were working one year after CABG. Five years postoperatively, 85% of patients younger than 60 years and once returned to work were still working. Correspondingly, of subjects remaining under 60 years during a 10-year follow-up, 75% continued working.

CONCLUSIONS

Younger age and preoperative employment were the most important predictors of successful return to work. Once returned after CABG, patients' staying at work was comparable with that in the general population.

Impact of an early recovery management intervention on functioning in postoperative coronary artery bypass patients with diabetes

BACKGROUND

Approximately 30% of patients undergoing coronary artery bypass graft (CABG) procedures have diabetes and, as such, are at increased risk for postoperative complications and a lengthy recovery.

OBJECTIVE

To test the feasibility of an in-home early recovery management intervention to improve physical and psychosocial functioning in the diabetic CABG population.

METHODS

This pilot study was a 2-group, randomized, experimental study. The 6-week in-home early recovery intervention was delivered by way of a device called the Health Buddy (Health Hero Network, Redwood City, CA). Subjects were 49 diabetic patients who had undergone a first-time CABG procedure.

RESULTS

Although no statistical differences between groups were found, descriptively, the intervention group's baseline means on Medical Outcomes Study Short Form-36 subscales measuring physical functioning were lower but improved to levels comparable with that of the control group. Improvements in psychosocial functioning were comparable between the 2 groups.

CONCLUSION

This in-home telehealth intervention may have promise for improving functioning outcomes in high-risk CABG patients with diabetes. However, weaknesses of the intervention and the need for a more focused, directive intervention were identified.

Two-year outcomes in patients with mild refractory angina treated with enhanced external counterpulsation

BACKGROUND

In the International Enhanced External Counterpulsation Patient Registry (IEPR), approximately 85% of the patients treated are in Canadian Cardiovascular Society (CCS) class III-IV with no option for further invasive coronary revascularization procedures.

HYPOTHESIS

This study sought to determine whether it is clinically important to establish whether the observed durable reduction in disabling severe angina with enhanced external counterpulsation (EECP) treatment can be extended to those with less severe CCS class II angina, who also have no option for further revascularization.

METHODS

This study evaluated the immediate response, durability and clinical events over a 2-year period after EECP treatment in 112 patients with Canadian Cardiovascular Society (CCS) class II angina versus 1346 patients with class III-IV angina using data from the International EECP Patient Registry (IEPR).

RESULTS

Treatment with EECP significantly (by at least one CCS class) reduced angina frequency, nitroglycerin use, and improved quality of life in both groups. At 2-year follow-up, 74% of class II and 70% of class III-IV patients remained free of major adverse cardiovascular events (MACE) and continued to demonstrate a durable CCS class improvement over baseline.

CONCLUSION

The robust effectiveness of EECP as a noninvasive device, together with its relatively low start-up and recurrent costs, makes it an attractive consideration for treating patients with milder refractory angina in addition to the patient with severely disabling angina treated in current practice.

Changes in bone mineral and body composition following coronary artery bypass grafting in men

This study investigated bone mineral and body composition changes after coronary artery bypass grafting (CABG) in men. Twenty-six men 50 to 79 years of age underwent CABG for multivessel coronary disease. Dual-energy x-ray absorptiometry was performed before surgery and 3 months and 1 year after treatment to assess bone mineral content (BMC), bone mineral density (BMD), and body composition. Through 3 months after treatment, BMD decreased at the total body, arms, and pelvis. BMC of the arm decreased and losses at the total body and legs approached significance. Fat-free mass decreased in the arms and total body but not in the legs. Neither total body nor regional fat mass changed. At the 1-year follow-up visit, 15 of the initial 26 subjects returned for dual-energy x-ray absorptiometry. Compared with before treatment, BMD decreased at the total body and legs, whereas losses at the arms approached significance. Arm BMC decreased over the 1-year post-treatment period. No changes were observed in body composition. In conclusion, CABG and the ensuing convalescence period results in considerable arm bone mineral losses through 1 year after treatment.
