Assessment of Coronary Plaque Composition Using Optical Coherence Tomography

Overview

About this study

The investigators hypothesis is that local activation of the endogenous Lp-PLA2 plays an integral role in early atherosclerosis, and contributes to the mechanism of coronary endothelial dysfunction and to the structural and mechanical properties that characterize plaque vulnerability. Thus, the investigators study will characterize prospectively the correlation between the functional and structural vascular wall properties, and the activity of the Lp-PLA2 pathway.
