METHOD FOR PREDICTING STENOSIS OF CORONARY ARTERIES Russian patent published in 2005 - IPC

FIELD: medicine, cardiology.

SUBSTANCE: one should carry out multiplayer spiral computer tomography followed by reconstruction and analysis of pictures obtained during diastolic phase of cardiac cycle at trigger's shift for 5%, and at heart rate being above 70 beats/min - preliminary introduction of beta-blocking agents, moreover, to perform analysis one should apply pictures obtained in interval of 45-65% against the duration of cardiac cycle at delaying the trigger for 50% against the duration of cardiac cycle at heart rate being below 60 beats/min, at heart rate being 60-65 beats/min - for 55%, at heart rate being equal to 65-70 beats/min - for 60-65% and at heart rate being above 70 beats/min - for 45%, and at detecting narrowing and/or occlusion in the lumen of coronary arteries one should diagnose stenosis. Moreover, at heart rate being equal to 65-70 beats/min, one should delay the trigger for the trunk of left-handed coronary and left-handed anterior descending arteries for 65% against the duration of cardiac cycle, and for left-handed rounding and dextral coronary arteries - for 60%.

EFFECT: higher efficiency of diagnostics.
