Values are presented as n (%) or mean ± SD. Bold p values are statistically significant.

BMS = bare-metal stent(s); hetero-DES = implantation of stent eluting a different drug; homo-DES = implantation of stent eluting the same drug; IVUS = intravascular ultrasound; max = maximum; POBA = plain old balloon angioplasty; other abbreviations as in Table 1.
