[Diagnostic possibilities of radionuclide methods of studying patients with stable and unstable angina pectoris].

Myocardial radiocardiography and scintigraphy with 99mTc-pyrophosphate was performed in 58 patients with stable angina and 60 patients with unstable angina. In patients with stable angina, positive scintigrams were mostly recorded after anginal attacks. Their central hemodynamic parameters deteriorated progressively as angina increased in severity.

[Dynamics of electrocardiographic, cardiohemodynamic and biochemical indices as affected by intensive bicycle ergometer training in stenocardia patients].

Intensive training in patients with IHD suffering from attacks of angina pectoris helps to enhance tolerance to exercise and to increase the volume of the work performed. In response to the threshold exercise the degree of pathological displacement of ST segments on ECG diminishes and in 34% of patients with the initial signs of coronary insufficiency the ECG parameters return to normal. The cardiohaemodynamic picture points to the economical activity of the cardiovascular system in performing "preischaemic" exercise and to the improvement of the reaction both at the expense of exercises.
