Titles & IDs
Public title
A substudy of the PLAPCI trial comparing Phospholipase A2 release with tissue characteristics as determined by invasive ultrasound and infrared imaging of the heart arteries in patients with coronary artery disease undergoing coronary artery stenting.
Scientific title
The release of Phospholipase A2 biomarkers during percutaneous coronary intervention in patients with significant coronary artery disease and the relationship of released biomarkers with optical coherence tomography and intravascular ultrasound tissue characterisation.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Invasive imaging of the coronary arteries prior to and after elective coronary stenting with optical coherence tomography and intravascular ultrasound. Imaging will take place on two occasions approximately 30 minutes apart and will take 15-20minutes to perform on each occasion.

Outcomes
Primary outcome [1] 269344 0
To test the hypothesis that a greater percentage of coronary lipid core and the presence of thin cap fibro-atheroma as assessed by IVUS and OCT will correlate with greater relative PLA2 release during elective percutaneous coronary intervention and to identify which PLA2 assay shows the greatest correlation

Summary
Brief summary
The aim of this study is to assess the effect of elective coronary stenting procedures on the release of enzymes (PLA2) found in the wall of the coronary artery, and how this release relates to the characteristics of the artery wall as assessed by novel invasive imaging tools
