[The possible significance of coronary vascular resistance in chronic ischemic heart disease].
From a pool of patients, treated because of cardiac diseases on ward for 4 years, 8 subjects, the mean age of which amounted to 46 (SD 12) years, showing stable angina pectoris in usual physical activity, were chosen. In these patients widespread examinations including invasive procedures had not been evident for one of the well defined heart diseases. In two patients dysrhythmias appeared during standardized exercise test while in four other subjects acute cardiac findings consisted of chest pain, significant depression of ST segments or inversion of T waves were observed. One patient had a normal result of the exercise test. A myocardial thallium-201 imaging was performed in four subjects. In three patients imaging showed questionable or mild signs of ischemia. The result suggest the existence of unknown shapes in coronary heart disease, the origin of which is possibly connected with a disorder of microvascular smooth muscle reactivity.
