[Use of prazosin and capoten in the treatment of heart failure in patients with ischemic heart disease].

Eighty eight patients with ischemic heart disease were studied. There was a significant increase in pulmonary blood flow time (Tp), pulmonary blood volume (BVp). mean pulmonary pressure (MPP), and total pulmonary resistance (TPR).

[Clinical evaluation of dynamic scintigraphy of the myocardium with Tl-201 in patients with acute myocardial infarction].

Thirty-six patients hospitalized because of suspicion for acute myocardial infarction (AMI) were examined within the first 24 hours after symptoms of the disease manifested themselves and during the follow-up on days 5-6 and 28-30. Myocardial perfusion was examined using the technique of perfusion myocardial scintigraphy with 201Tl. In cases of an uncomplicated course of AMI, the scintigrams showed a reduction in the area of perfusion defects (a positive time-course) whereas when the disease progressed the scintigrams reflected a negative time-course expressed in an expansion of the area of perfusion defects.

[Semiquantitative assessment of myocardial scintigrams using 201Tl].

A program for an automated semiquantitative evaluation of myocardial scintigrams with 201Tl was proposed. Altogether 11 healthy subjects and 34 patients with acute myocardial infarction were examined. The patients have shown a significant decrease (p less than 0.
