Insights
Five years after Coronary Artery Bypass Graft Surgery (CABGS), patients generally report good health-related quality of life (HRQoL) and remain asymptomatic. However, data collection methods impacted physical HRQoL results.
Area of Science:
- Cardiology
- Health Outcomes Research
- Quality of Life Studies
Background:
- Coronary Artery Bypass Graft Surgery (CABGS) is increasingly performed for coronary artery disease.
- Understanding long-term patient outcomes is crucial for surgical effectiveness and patient care.
Purpose of the Study:
- To assess health-related quality of life (HRQoL) five years post-CABGS.
- To describe patient characteristics and symptom status (angina, breathlessness) after CABGS.
- To compare HRQoL based on data collection methods.
Main Methods:
- A follow-up study involving 128 patients who underwent CABGS.
- Utilized the Short-Form 36 (SF-36) questionnaire to measure HRQoL.
- Assessed angina and breathlessness symptoms at follow-up.
Main Results:
- Patients reported generally good physical and mental health scores on the SF-36.
- Face-to-face interviews yielded higher physical component summary scores (PCS) than postal questionnaires (45.8 vs. 30.8).
- Most patients were asymptomatic for angina and breathlessness compared to pre-operative status.
Conclusions:
- Patient-perceived HRQoL is generally favorable five years after CABGS.
- Patients remain largely asymptomatic post-surgery.
- Data collection methodology influences reported physical HRQoL outcomes.
Background:
The number of individuals undergoing Coronary Artery Bypass Graft Surgery (CABGS) to treat coronary artery disease is steadily increasing.
Aim:
The purpose of the study was to describe the cohort's characteristics, their angina and breathless symptoms and report health-related quality of life (HRQoL) five years after CABGS.
Methods:
One hundred and twenty-eight patients participated in the follow-up study using the quality of life Short-Form 36 (SF-36) questionnaire. Angina and breathless symptoms were also recorded.
Results:
One hundred and nine patients were interviewed (face-to-face) and 19 completed postal questionnaires. The SF-36 component summaries of the face-to-face patients indicated that their physical (PCS) and mental (MCS) health was relatively good (45.8 and 53.6, respectively, with 0=worst health and 100=best health and 50 being the mean score), compared to the postal patients' mean PCS of 30.8 (p<.001). The postal MCS was also lower but not statistically significant (49.6, p=.081). At follow-up, the majority of patients were asymptomatic in terms of angina and breathlessness compared to their pre-operative status.
Conclusion:
The findings demonstrate that patient perceived HRQoL five years after CABGS is generally good and patients remain relatively asymptomatic although data collection methods highlight differences in physical HRQoL.
