Brief summary

Patients who present with an acute coronary syndrome remain at high risk of further events in subsequent years. Better identification of individuals at high risk can allow better targeting of novel therapies and resources. This study will create an imaging bio-bank that enables testing of multiple novel strategies involving new imaging, image analysis and biomarker approaches alone or in combination for improved risk stratification and targeting of prevention. Prospective follow-up in the cohort for outcomes enables the predictive value to be tested in a pilot data setting.

Interventions

High resolution catheter based laser imaging using optical coherence tomography (OCT) is used during coronary angiography. It is a routine procedure used in select patients (at the Cardiologists discretion) to view high resolution images from inside the blood vessels. The OCT imaging will add 10- 15 minutes to the angiogram procedure. A functional PET scan that detects the activity of coronary calcium build-up will take approximately 30 minutes. It is not a routine procedure. Blood samples wil

High resolution catheter based laser imaging using optical coherence tomography (OCT) is used during coronary angiography.

The OCT imaging will add 10- 15 minutes to the angiogram procedure. A functional PET scan that detects the activity of coronary calcium build-up will take approximately 30 minutes. It is not a routine procedure. Blood samples will be taken at the baseline assessment (once consent is given) and stored to establish a bio-bank. The samples will be used investigate how fast atherosclerosis and calcium build-up occurs in the coronary arteries. A CT-scan that determines 3-dimensional trajectory for calculation of stress distribution on artery walls is a commonly used imaging modality in patients. This scan also takes approximately 30 minutes.
