Exercise tolerance and work ability following aorto-coronary bypass surgery

Area of Science:

• Cardiology
• Rehabilitation Medicine
• Public Health

Background:

• Aortocoronary bypass surgery is a common intervention for coronary artery disease.
• Assessing long-term functional outcomes and return-to-work status is crucial for patient well-being and healthcare system evaluation.

Purpose of the Study:

• To investigate the primary reasons for disability pension acquisition among patients following aortocoronary bypass surgery.
• To evaluate the relationship between physical work capacity and the decision to grant disability pension.

Main Methods:

• A cohort of 250 patients undergoing aortocoronary bypass surgery between March 1983 and November 1985 was studied.
• Follow-up examinations, including exercise tests, were conducted on survivors at a mean of 4.9 years post-operation.
• Data on disability pension status and physical work capacity were collected and analyzed.

Main Results:

• Physical work capacity significantly increased post-surgery, from 92.2 W preoperatively to 119.3 W at follow-up (p < 0.001).
• Despite improved physical capacity, 72 out of 219 survivors received disability pension.
• Electrocardiogram (ECG) test positivity rates were similar between working patients and those on disability pension.

Conclusions:

• A significant proportion of patients receiving disability pension after bypass surgery demonstrated adequate physical capacity for employment.
• Factors beyond objective physical working capacity, such as subjective assessments or other non-physical criteria, appear to play a substantial role in disability pension decisions.
• Further research is warranted to fully understand the multifaceted reasons behind disability pension awards in this patient population.
