Variable	OMT (n=52)	PCI (n=52)
NYHA Class
1	31 (59.6%)	39 (75%)
2	13 (25%)	9 (17.3%)
3	4 (7.6%)	2 (3.8%)
4	3 (5.7%)	2 (3.8%)
CCS Class*
1	11 (21.2%)	14 (26.9%)
2	30 (57.7%)	30 (57.7%)
3	4 (7.7%)	4 (7.7%)
4	7 (13.5%)	4 (7.7%)
Previous PCI	28 (53.8%)	36 (69.2%)
Previous MI	21 (40.4%)	31 (59.6%)
Presentation
Stable angina	32 (61.5%)	21 (40.4%)
Non-culprit NSTEMI	12 (23.1%)	17 (32.7%)
Unstable angina	3 (5.8%)	3 (5.8%)
Non-culprit STEMI	5 (9.6%)	11 (21.2%)

CCS Class may not be indicative of anginal class as per Seattle Angina Questionnaire in the setting of non-culprit disease where scores were calculated at a minimum of 4 weeks post initial PCI in order to ensure scores were reflective of angina from the ^GZFFR vessel under study.

CCS, Canadian Cardiovascular Society; NSTEMI, non-ST elevation myocardial infarction; OMT, optimal medical therapy group; PCI, percutaneous coronary intervention; STEMI, ST elevation myocardial infarction.
