Scintigraphy with pyrophosphate 99mTc was performed in 230 patients with various forms of ischemic heart disease and in 15 persons with pain in the region of the heart caused by osteochondrosis of the cervical and thoracic spinal segments or vegetovascular dystonia (control group). It was found that labelled purophosphate accumulated in the myocardium in necrosis of the heart muscle or when coronary insufficiency takes a course in which necrosis of the myocardial cells is quite possible. Positive results of scintigraphy with pyrophosphate 99mTc are not a strict criterion of acute myocardial infarction because they are also encountered in a chronic course of ischemic heart disease and are evidence in this case that "a state of risk" has occurred during the disease.

The effect of psychophysiologic testing (the information test) on coronary flow was examined in 113 patients with coronary heart disease, 48 patients with neurocirculatory dystonia, 10 patients with essential hypertension and 15 normal subjects. Electrocardiographic evidence of coronary insufficiency was identified that can be found in 75.2% of coronary patients.

Exercise was found to produce pseudoischemic changes of ST segment in 6% of patients with neurocirculatory dystonia, and T-wave inversion in 15-16%, which may be due to hyperventilation. It was demonstrated that T-wave inversion could not be a reliable indicator of coronary insufficiency, nor could respiratory alkalosis, hypocapnia, tachycardia, increased work of respiratory muscles, hypoxemia be immediate causes of hyperventilation changes. It is suggested that the changes in question are related to disrupted vegetative control of the cardiovascular system.

It is established that the strength of both hands is much weaker in patients with angina pectoris than in healthy individuals. Development of an atypical cardiac pain syndrome leads to a significant diminution in the strength of the left hand of patients with angina pectoris and to a considerable reduction in endurance. In patients with cardiac-type neurocirculatory dystonia, the strength in the left hand and the endurance of isometric exertion are diminished. The endurance of dynamic exertion is sharply reduced in patients with chronic coronary insufficiency. Physical working capacity is substantially higher in patients with cardiac-type neurocirculatory dystonia than in those with angina pectoris and lower than in practically health individuals.

Comparative study of pathomorphology of myocardial circulation under conditions of increased afterload of the left or right ventricles showed similar changes. All compartments of the coronary bed were plethoric, capillary blood stasis and perivascular edema, more pronounced in arterial vessels, were detected in both cases. These changes equally involved both ventricles and the ventricular septum. Significant differences consisted in local increase in the density of functioning capillaries. The increase was the maximum in hemodynamically overloaded ventricle and ventricular septum, presumably due to increase of their contractile activity. The density of functioning capillaries in the intact (vs. pressure overloaded) ventricle also increased, but to a lesser degree, which could be due to systemic neurohumoral effects. If increased afterload was complicated by the development of heart failure, circulatory disorders in the myocardium progressed. Significant increase in the density of functioning capillaries in all cardiac compartments indicated decreased vascular tone and exhaustion of coronary reserve. This was paralleled by a sharp arterial plethora in case of increased afterload of the left ventricle and sharp blood stasis in the microcirculatory bed in case of increased right ventricle afterload. Reduction of effective perfusion pressure in the presence of coronary dystonia can cause coronary insufficiency and myocardial ischemia in case of increased right ventricle afterload.

Clinical syndromes induced by high intensity radiofrequency electromagnetic field chronic exposure are described. Persons injured by occupational exposure have been observed central nervous system changes in diencephalic syndrome form, cardio-vascular system changes revealed in atherosclerosis, isch(a)emic heart disease and coronary insufficiency rapid progressive expansion. General public living in territory of radar station exposure zone different functional disorders have been identified: vegetative dystonia (asthenovegetative syndrome), thrombocytopenia, decrease of blood coagulation index, and thyroid gland function changes. Observed diseases clinical variability may be determined by electromagnetic exposure characteristics.
