Abstract / Description of output

OBJECTIVES:
To determine whether socioeconomic status (SES) influences clinical outcomes and quality of life after percutaneous coronary intervention (PCI).
DESIGN:
Prospective observational study.
SETTING:
Two interventional cardiac centres.
PARTICIPANTS:
1346 consecutive patients undergoing PCI over a 12-month period. Outcomes: Self reported health-related quality of life (HRQoL; EuroQol-5 Dimensions (EQ-5D); EuroQol Visual Analogue Scale (EQ-VAS)), repeat angiography, revascularisation, hospital admission, myocardial infarction and death within 12 months, by SES derived using postal address code.
MAIN RESULTS:
No significant differences were found between patients with high and low SES in the occurrence of repeat angiography (p = 0.55), repeat revascularisation (PCI, p = 0.81, CAEG, p = 0.27), total cardiac hospitalisation (p = 0.10), myocardial infarction (p = 0.97) or death 12 months after PCI (p = 0.88). Non-procedure-related readmissions were higher in patients with low SES (18.6% v 13.7%; p = 0.025). After adjustment for confounding factors, patients with low SES had lower HRQoL scores at baseline (95% CI for difference 0.01 to 0.14; p = 0.003) and at 12 months (95% CI 0.07 to 0.17; p<0.001) compared with those with high SES.
CONCLUSIONS:
Clinical outcomes were similar for patients in different SES groups. Patients with low SES had considerably more non-procedure-related readmissions and lower quality-of-life scores. Future studies on HRQoL after coronary revascularisation should take account of these important differences related to SES.
