Hazard ratios for likelihood of percutaneous coronary intervention and coronary artery bypass grafting after coronary angiography (n = 30 358)*
Treatment | No. (%) of patients | Unadjusted HR (95% CI) | Adjusted HR (95% CI) | ||
---|---|---|---|---|---|
Non–First Nations (n = 29 652) | First Nations (n = 706) | Partial adjustment† | Full adjustment‡ | ||
PCI | 17 503 (59.0) | 381 (54.0) | 0.89 (0.80–0.98) | 0.89 (0.80–0.99) | 0.92 (0.83–1.02) |
CABG | 4 179 (14.1) | 108 (15.3) | 0.96 (0.79–1.16) | 1.04 (0.86–1.25) | 1.03 (0.85–1.25) |
Note: CABG = coronary artery bypass grafting, CI = confidence interval, HR = hazard ratio, MI = myocardial infarction, PCI = percutaneous coronary intervention.
↵* Reference category is non–First Nations status.
↵† Adjusted for age, sex, diabetes, hypertension, year of acute MI diagnosis, comorbidities listed in Table 1, ejection fraction, smoking status and coronary anatomy.
↵‡ Adjusted for age, sex, diabetes, hypertension, year of acute MI diagnosis, comorbidities listed in Table 1, ejection fraction, smoking status, coronary anatomy, income quintiles and distance to closest cardiac catheterization laboratory.
