Computed tomography (CT) is the only non-invasive method of coronary lumen and walls imaging and assessment of lumen stenosis degree.

Purpose. To compare CT data with invasive coronary angiography (CAG) and intravascular ultrasound (IVUS) in evaluation of coronary stenosis degree.

Materials and methods. Thirty-six patients with ischemic heart disease were included. All patients were hospitalized in the department of emergency cardiology of Russian Cardiology Research and Production Complex. We compared CT, IVUS and CAG results in all patients. The influence of positive remodeling on some discrepancy in measurements of coronary stenosis degree was assessed by these methods.

Results. It was found that the assessment of coronary stenosis degree with CT is possible approached to IVUS results. CAG had a tendency to ”underestimate” stenosis degree in comparison with IVUS and CT results. Dependencies between the positive remodeling of the coronary arteries and stenosis degree “underestimation” by CAG in comparison with IVUS and CT have not been identified.

Conclusions. CT results are correlated well with IVUS data. CAG results show a tendency to “underestimate” stenosis degree compared with IVUS and CT.
