Altogether 111 patients with coronary heart disease (CHD) were examined using loading perfusion scintigraphy testing of the myocardium with 201Tl. Quantitative assessment of scintigrams was based on a computer-assisted method proposed by the authors which was used for determination of indices characterizing a degree of perfusion disorder in each segment of the left ventricular myocardium: the M/B ratio (the ratio of a mean level of radioactivity of a myocardial segment to a mean level of background radioactivity) and the TAI (the thallium accumulation index--a quantitative value of segmental perfusion). The method permits the detection of a zone of disturbed perfusion (ischemia, scar changes and left ventricular aneurysm) and quantitative assessment of the depth of scar lesion of the left ventricular myocardium. |
