title: [Interrelation of the state of perfusion and the coronary vascular bed in patients with chronic ischemic heart disease].
abstract: Coronary angiographic and scintigraphic (using 201Tl) studies in 139 patients with verified diagnosis of chronic coronary heart disease demonstrated high sensitivity (85.6%) of myocardial perfusion scintigraphy with respect to detecting disorders of myocardial blood supply due to the stenosis of major coronary arteries and microcirculation disorders. False negative scintigraphic results in the screening for perfusion defects are commonly due to the shortcomings of semiquantitative assessment of the scintigrams.
