COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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
