Coronary Artery Plaque Burden in Stable Angina and Non-obstructive Coronary Artery Disease

Overview

Non-obstructive coronary artery disease (CAD), particularly common in women, has been associated with impaired quality of life and risk of recurrent hospitalizations. Several studies have also demonstrated increased risk of incident acute coronary events and mortality. The main objective of the project is to assess the association between coronary artery plaque features by coronary CT angiography and long term prognosis in a large unselected population undergoing CT coronary angiography due to stable angina and suspected myocardial ischemia from the Norwegian Registry for Invasive Cardiology (NORIC) diagnosed with non-obstructive CAD by coronary CT angiography.

Patients with stable angina and non-obstructive coronary artery disease by CT coronary angiography will be selected from the Norwegian Registry of Invasive Cardiology (NORIC). This is a national quality control registry run and controlled by the Norwegian Institute of Public Health (www.fhi.no). All CT coronary angiograms will be reanalyzed using advanced post-processing analysis software to assess coronary artery plaque burden, distribution and composition. Through linking with the Norwegian Cardiovascular Disease Registry and the Cause of Death Registry (www.fhi.no) we will be able to assess the association between long-term prognosis (5 years) and coronary artery plaque features.
