[Study of myocardial perfusion in patients with hypertension].
Exercise 199Tl myocardial scintigraphic data were studied during dipyridamole test in 39 patients with Class II essential hypertension. Transient myocardial perfusion defects were revealed in 60% of patients with negative exercise test. Intraventricular administration of albumin microspheres in 8 females with normal coronary artery allowed the authors to detect areas of their accumulation at the same sites as in exercise 199Tl myocardial scintigraphy. Thus, the changes in the small vessels which are revealed by intraventricular albumin microspheres are one of the causes of impaired myocardial perfusion in patients with essential hypertension.
