Number of participants that the trial has enrolled

264

Results

We enrolled 264 consecutive patients treated with an EES who underwent follow-up OCT six to 12 months . PLIA was identified in 102 patients; 162 patients did not exhibit PLIA. PLIA (PLIA+) was an independent risk factor for an increased incidence of TLR . In both the early (<1 year) and late (>1 year) phases, the incidence of TLR was significantly higher in the PLIA+ group. Current smoking and increased C-reactive protein level were independently associated with PLIA+ .

Baseline Characteristics

The Kobe University Hospital OCT registry is a single-centre registry of consecutive patients who underwent OCT of the coronary arteries between April 2011 and March 2015. During this period, OCT was performed because of 1) planned follow-up coronary angiography and OCT for routine stent follow-up or for other study protocols, regardless of symptoms, and 2) evidence of myocardial ischemia such as silent myocardial ischemia, stable angina, or acute coronary syndrome (ACS). Patients enrolled in the registry who met the following criteria were included: 1) treatment with everolimus-eluting stents (EES; XIENCE V, Abbott Vascular, CA, USA, or Promus Element, Boston Scientific, Natick, Massachusetts) and 2) follow-up OCT examination 6-12 months after stenting. Among these patients, we excluded those with 1) a stent implanted in the left main trunk or 2) insufficient quality of OCT images.

Participant flow

Clinical outcome data were obtained by reviewing outpatient records or telephone interview for death, myocardial infarction (MI; defined according to the World Health Organization definition using creatine kinase and creatine kinase-MB increases), target lesion revascularisation (TLR), and a composite of death, MI, and TLR (MACE). TLR was performed clinically. These data were obtained by personnel blinded to follow-up OCT findings.

Adverse events

nothing

Outcome measures

The primary endpoint of this study was TLR during the follow-up period. TLR required >1 year after PCI was defined as late-phase TLR . All deaths were considered cardiac-related unless an unequivocal noncardiac cause could be established.
