[Use of isometric exercise to enhance the diagnostic value of dipyridamole testing in patients with angina pectoris].

A dipyridamole test was performed in 40 patients with coronary heart disease who were divided into 2 groups, each consisting of 20 subjects. The dipyridamole test alone was performed in the patients from Group 1, while the agent was given by using manual dynamometry and increasing venous return in those from Group 2. Positive results were obtained in 55 and 85%, respectively (p less than 0.

[Use of a static exercise test for evaluating anti-angina effects of drugs in patients with ischemic heart disease at a polyclinic].

Only in 115 of 320 patients who had attended the polyclinic for cardialgias, static exercise and bicycle ergometer tests could be performed because of medical contraindications and the patients' refusal to participate in the investigation. Positive results were found in 15 patients who had undergone bicycle ergometer tests and in 12 patients who did static exercise. It has been shown that static exercise tests may be useful for selecting antianginal drugs (glyceryl trinitrate, anapriline, corinfar) for outpatients with coronary heart disease on an individual basis.

[Changes in arterial pressure, heart contraction rate and ECG indices in ischemic heart disease patients undergoing static-dynamic loading].

Thirty males with coronary heart disease were examined using bicycle ergometry and a combined statico-dynamic test. It was established that the latter was accompanied by a more rapid (as compared with bicycle ergometry) increase of the heart rate, the systolic arterial pressure, the value of "double multiplication" and, in contrast to dynamic exercise, by an elevation of the diastolic arterial pressure. During a combined test an anginal attack and displacement of the ST segment occurred earlier as against bicycle ergometry.
