[Morphometric evaluation of atherosclerotic constrictions of the coronary arteries]. / Morfometricheskaia otsenka ateroskleroticheskikh suzhenii koronarnykh arterii.

A method is proposed for objective assessment of the degree of stenosis in atherosclerotically-involved coronary arteries through their direct measurement. The results were compared with those obtained using the conventional subjective procedure. The findings coincided in 7 (8%) of 88 assessments. The difference was below +/- 5% in 18 (20%) cases, ranged between +/- 5-10% in further 30 (34%) and exceeded 8 +/- 10% in 33 (38%) cases, reaching +/- 15-20% in 11 (12%) of those. The results suggest that the morphometric technique should be used more extensively for the assessment of atherosclerotically-stenosed coronary arteries.
