| Level of certainty | Myocardial infarction (n = 246) | Coronary revascularization | Angiographic coronary stenosisa | Angina |
|---|---|---|---|---|
| Definite | Validated MI (n = 157; 63.8%) | Surgical or medical index code for CABG or PCI (n = 472) | Confirmed by cardiac catheterization lab (n = 419) | -- |
| Probable | Self-report and medical index code (n = 89; 36.2%) | Self-report + medication + medical index code (n = 118) | ||
| Medication + medical index(n = 32) | ||||
| Self-report and medical index code (n = 167) |
MI = myocardial infarction; CABG = coronary artery bypass grafting; PCI = percutaneous coronary intervention.
