Comparison of the studies looking at vasomotion in patients treated with PCI.

Author	Number of Patients	Methods	Time scale	Result
Komaru et al. [114]	13	Patients treated with POBA for stable angina. Measured vasomotion with IC substance P	Measured the day after angioplasty and three months afterwards	The “day after” there was a vasoconstrictor response. More uniform vasodilator response after three months
Vassanelli et al. [58]	25	Patients treated with POBA assessed with IC ACH	Three months and six months after treatment	Abnormal vasomotor responses at both three and six months
Caramori et al. [115]	39	Post-treatment to their LAD artery with POBA and BMS with IC ACH	Six months	Significantly greater vasoconstrictor responses with BMS vs. POBA (-21.8% ± 4.3 vs. -9.5% ± 2.8, p=0.02)
Togni et al. [116]	25	Treated 11 with BMS and 14 with SES Angiography during exercise	Six months	Exercise-induced vasoconstriction in SES compared with BMS
Kim et al. [28]	78	10 received BMS, 36 received PES, and 39 DES assessed with IC ACH. Measured responses within stents as well as proximally and distally	Six months	Vasoconstriction with DES even proximally and distally that was worse than BMS
Gomez-Lara et al. [109]	59	Non-diabetic patients randomised to either BVS or Everolimus DES measured response to IC ACH	13 months	More pronounced in scaffold vasoconstriction in BVS than DES
MAGSTEMI [109]	69	STEMI patients treated with BVS vs. SES	12 months	More pronounced vasoconstrictive response with BVS vs. SES
