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

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.
