Abstract:

Aim: was to improve the efficiency of diagnosis of patients with coronary heart disease, by estimating of possibilities of cardiac multislice computed tomography in comparison with coronary angiography.

Materials and methods: study included 64 patients (18 women and 46 men, mean age 62,4 ± 9,5 years) with a high risk of developing coronary heart disease. In 34 patients - myocardial infarction in anamnesis (18 patients - in pool right coronary artery in 16 patients - in left anterior descending artery). Clinics of angina pectoris - in 40 patients (functional class (FC) I - 10; FC II - 22, FC III - in 6, FC IV - 2 patients). Selection criteria: the absence of disease progression for at least 6 weeks, and at least 3 months of optimal treatment. All patients underwent cardiac MSCT at 256-slice CT scanner. Obtained data was compared with data of reference method - x-ray coronary angiography.

Results: comparison of MSCT coronary angiography with invasive data showed a high comparability of results of two methods in the evaluation of coronary artery disease. It was revealed that discrepancies between cardiac MSCT and CAG in detection of hemodynamically insignificant stenoses ranging from 0 to 4%, hemodynamically significant stenoses - from 0 to 2.6%, subtotal stenosis - from 0 to 1%, occlusions - 0%. The presence of strong correlations between data of cardiac MSCT and coronary angiography of stenosis, demonstrated the high quality of MSCT imaging of coronary artery segments in the examination with a variety of modes of application method.

Conclusion: multislice computed tomography is a highly effective method for diagnosing of structural and anatomic changes of coronary arteries in patients with coronary heart disease.
