No problem	76 (67)	46 (62)	30 (75)	0.19
Having problems	37 (33)	27 (37)	10 (25)	0.19
EQ-5D-5L (Mean ± SD)	0.88 ± 0.15	0.87 ± 0.15	0.89 ± 0.15	0.37^b
EQ-VAS (Mean ± SD)	65.6 ± 13.3	64.7 ± 13.4	67.1 ± 13.1	0.36^b

PCI: percutaneous coronary intervention; OMT: Optimal medical therapy; SD: Standard deviation; Higher EQ-5D-5L utility index score represents better quality of life. Higher EQ-VAS score represents better health status.
