Objectives

Narrative objectives1

To examine if angioscopic findings, especially the presence of yellow plaque, at one year after DES implantation would be a risk of future very late stent failure.

Assessment

Primary outcomes

Very late stent failure defined as 1) cardiac death, 2) myocardial infarction or unstable angina due to the target stent, or 3) target lesion revascularization. Cardiac death was defined as the death without known non-cardiac cause.

Results

In-stent atherosclerosis evaluated by yellow plaque at 1 year after the implantation of DES and the absence of statin therapy were risks of VLSF. The underlying mechanism of VLSF appeared to be the progression of atherosclerosis as demonstrated by the yellow plaque.

1) Yellow color, neointima coverage, and thrombus at the site of DES implantation will be examined by angioscopy. VLSF is defined as 1) cardiac death, 2) myocardial infarction or unstable angina due to the target stent, or 3) target lesion revascularization. Cardiac death is defined as the death without known non-cardiac cause.
2) The data on the patients background will be acquired from clinical record at the time of enrollment when angioscopic examination is performed.
3) Angioscopic observation of stented lesions is done while blood is cleared away from viewed by the injection of 3% dextran-40 as we have previously reported. Yellow color is classified into 4 grades (0: white, 1: slight yellow, 2: yellow, and 3: intensive yellow) comparing with standard colors as we have previously reported. Neointima coverage is classified into 3 grades (0: no coverage, 1: poor coverage, 2: complete coverage) as we have previously reported. Thrombus is defined as white or red material that had cotton-like or ragged appearance or that presented fragmentation with or without protrusion into lumen or adherent to the luminal surface. Maximum and minimum neointima coverage grade, maximum yellow color grade, and presence or absence of thrombus will be determined for each stented lesion. Presence of yellow plaque is defined as the maximum yellow color grade >=2.
4) Patients will be divided into 2 groups according to the presence or absence of yellow plaque at the site of stent implantation. Comparisons between the groups will be performed by unpaired student t-test or chi-square test. The incidence of VLSF will be compared between the groups using Kaplan-Meier methods and log rank test. To determine the risk factors for the occurrence of VLSF, multivariate Cox regression analysis will be performed.
