The data of intravital and postmortem coronary angiography were compared with those of morphological studies of the cardiac arteries in 20 patients with ischaemic heart disease. The purpose of the investigation was to study the correlation of the coronary lesion, including that of the distal arterial branches, by way of comparing intravital and postmortem coronary angiogrammes, with the data of morphological examinations of the cardiac arteries in cases of ischaemic heart disease. The errors of intravital diagnosis were found to comprise 12.7% and to be due to the nature of the anatomical lesion of the arteries, as well as to an incomplete opacification of the vessels in several observations. A term--vascular wall "resistance"--is introduced for the cases of extended atherosclerosis of the coronaries with distinct calcification and impaired mobility of the vessels, as shown by cineradiography. Intravital diagnosis of atherosclerosis of distal branches of the coronaries was found to be possible only in cases of stenosis exceeding 40--50%.
