Raghunathan, D. et .al [17] | 2011 | 30 | To examine whether an association exists between the presence and extent of LCP detected by NIRS performed before PCI with postprocedural MI | PCI of LCP-positive lesions is associated with increased risk for MI after PCI |

Brugaletta, S. et .al [26] | 2011 | 31 | To compare the findings of NIRS, IVUS virtual histology and grayscale IVUS obtained in matched coronary vessel segments of patients undergoing coronary angiography | Larger plaque area by grayscale IVUS was more often associated with either elevated percentage VH necrotic core or LCP by NIRS |
JACC Cardiovasc Imaging

Madder, R.D. et .al [10] | 2012 | 60 | To determine the frequency of LCP at target and remote sites in ACS vs. stable angina | Target lesion responsible for ACS were frequently composed of LCP; LCPs often were found in remote, non-target areas; LCPs were more common in patients with ACS vs. stable angina patients |
Circ Cardiovasc Interv
| ||||
Pu, J. et .al [13] | 2012 | 66 | To evaluate NIRS combined with IVUS to provide novel information of human coronary plaque characterization | Combining NIRS and IVUS contributes to the plaque characterization |

Dixon, S.R. et .al [23] | 2012 | 69 | To compare the target lesion length using NIRS combined with angiography vs. angiography alone | Patients undergoing stent implantation could have LCP extending beyond the intended treatment margins as defined using QCA alone |
Am J Cardiol
| ||||
Brugaletta, S. et .al [27] | 2012 | 202 | To explore a relationship between lipid plaque composition by NIRS and angiographic severity of coronary artery disease | Patients with highest Syntax score have a higher LCBI |
JACC Cardiovasc Imaging
| ||||
Brilakis, E.S. et .al [16] | 2012 | 9 | To investigate whether use of an embolic protection device might prevent complications of LCP interventions | Use of embolic protection devices frequently resulted in embolized material retrieval after stenting of native coronary artery lesions with large LCP |
Catheter Cardiovasc Interv
| ||||
Brugaletta, S. et .al [28] | 2012 | 68 | To assess LCP distribution in nonculprit coronary arteries using NIRS | LCP were mainly located in proximal portions of the LAD and LCX, and more uniformly distributed in the RCA; |
JACC Cardiovasc Imaging
| ||||
Kini, A.S. et .al [15] | 2013 | 87 | To determine the impact of short-term intensive statine treatment on intracoronary plaque lipid content | Short-term intensive treatment with statine may reduce lipid content in obstructive coronary lesions |
JACC
| ||||
Papayannis, A.C. et .al [24] | 2013 | 9 | To examine the association between presenting LCP (by NIRS) and poststenting thrombus formation (by OCT) | Stenting large LCPs may be associated with intrastent thrombus formation |
Catheter Cardiovasc Interv
| ||||
Townsend, J.C. et .al [29] | 2013 | 100 | To investigate, whether coronary bifurcations have higher levels of intracoronary LCP than non-bifurcation regions | Coronary bifurcations do not appear to have higher levels of intracoronary LCP than their comparative non-bifurcation regions |
Am J Cardiol
| ||||
Maini, A. et .al [30] | 2013 | 77 | To evaluate LCP modification with coronary revascularization and its correlation with periprocedural MI | Plaque modification may be performed successfully using interventional methods and can be evaluated with NIRS; axial plaque shifting is an acute prognostic marker for postprocedure MI |

Choi, B.J. et .al [33] | 2013 | 32 | To investigate whether coronary endothelial dysfunction is associated with the LCP in patients with early CAD | Patients with early CAD and endothelial dysfunction had a higher lipid content in the vascular wall than patients with normal endothelial function; |
