ABSTRACT

A total of 85 patients (68 with coronary heart disease in the presence of effort angina of various functional classes (a major group) and 17 with neurocirculatory++ dystonia and cardialgic syndrome (a control group)) were examined. Heart failure severity and blood flow distribution in the functioning myocardial areas were evaluated in transient ischemia induced by atrial pacing. Three levels of coronary venous blood flow were defined in patients with coronary heart disease. A relationship between the coronary blood flow, disease history duration, and coronary blood flow changes was examined in cardioselective exercise.
