Developmental phase



Assessment

Primary outcomes

The polarization characteristics (birefringence and degree of polarization resolution) of coronary artery lesions that develop ACS will be analyzed and compared with those of lesions in patients with CCS to identify determinants of ACS development (in patients who develop ACS due to in-stent restenosis or stent thrombosis, the polarization characteristics will be compared with those of in-stent neointima in patients with CCS).

Key secondary outcomes

1) Comparison of biomarkers (high-sensitivity CRP, high-sensitivity cardiac troponin I, CK-MB, IL-1beta, IL-6, MCP-1, MMP-2, MMP-9, MMP-13, adipokine) and polarization characteristics of coronary lesions
2) Evaluation of polarization characteristics of coronary lesions and acute response to stent therapy (stent expansion, stent-induced coronary dissection, slow-flow phenomenon, no-reflow phenomenon)
3) Coronary artery calcification angle, length, thickness, and polarization characteristics in relation to acute phase response to balloon dilation
4) Evaluation of chronic restenosis and predictors of chronic restenosis to treatment with drug-eluting balloons
5) Evaluation of stent restenosis and predictors by coronary CT or coronary angiography in the chronic phase
6) Progression of stenosis in non-responsible lesions by coronary CT or coronary angiography in chronic phase, evaluation of predictors
7) Comparison of peri-coronary adipose tissue attenuation index by coronary CT and polarization characteristics of coronary lesions
8) Comparison of coronary plaque volume and polarization characteristics by coronary CT
9) Comparison of lipid index and coronary plaque polarization characteristics by NIRS-IVUS
10) Comparison with coronary ischemia assessment (FFR, myocardial scintigraphy)
11) Combined events (all-cause mortality, cardiovascular death, myocardial infarction, unstable or stable angina requiring revascularization, stroke, transient ischemia, PCI / CABG, stent thrombosis and restenosis)
