Work status after coronary bypass surgery. A prospective randomized study with ergometric and angiographic
Acta Medica Scandinavica
|January 1, 1979
Summary
Coronary bypass surgery significantly improved return to work rates for patients with coronary heart disease compared to medical therapy alone. Surgical intervention led to better functional capacity and exercise tolerance, enhancing work status post-treatment.
Area of Science:
- Cardiology
- Cardiac Surgery
- Occupational Health
Background:
- Coronary heart disease (CHD) significantly impacts patients' ability to work.
- Return to work is a crucial indicator of recovery and quality of life after cardiac events.
- Optimal treatment strategies for maximizing return to work in CHD patients require further investigation.
Purpose of the Study:
- To compare the rate of return to work in patients with coronary heart disease treated with either medical therapy or coronary artery bypass graft (CABG) surgery.
- To evaluate functional capacity and exercise tolerance in relation to treatment modality and work status.
- To determine the relationship between revascularization completeness and post-treatment work status.
Main Methods:
- Randomized controlled trial comparing medical therapy versus CABG surgery in 50 patients each.
- Assessment of work status at 2-year follow-up.
- Evaluation of functional classification of angina pectoris and exercise tolerance via ergometry.
- Postoperative angiography to assess graft patency and completeness of revascularization.
Main Results:
- Significantly higher proportion of patients returned to work after CABG surgery (60%) compared to medical therapy (26%) at 2-year follow-up (p < 0.05).
- Surgical group demonstrated superior functional classification of angina and exercise tolerance.
- Completeness of revascularization was positively correlated with work status in the surgical group.
Conclusions:
- Coronary artery bypass graft surgery is more effective than medical therapy alone in facilitating return to work for patients with coronary heart disease.
- Improved functional capacity and complete revascularization are key factors contributing to successful return to work after surgical intervention.
- A combined approach of surgery and medical therapy, when indicated, offers superior outcomes for work status in CHD patients.
