title: [Pain sensitivity threshold in patients with ischemic heart diseases with and without stable angina with episodes of "silent" myocardial ischemia].
abstract: A total of 124 coronary patients were examined. Group I comprised 52 patients with stabile angina, group II was 72 patients free from angina. In all patients, 24-hour ECG monitoring was carried out together with veloergometry (VEM), coronaryangiography. Determined in the above patients was also threshold of pain sensitivity (PST) by using the precardiac area electroskin stimulation technique. The frequency of pain-free episodes of myocardial ischemia (PFMI) in subjects with stabile angina has not been found to be different from that in those free from it. There was no difference in depth and duration of depression of ST segment either. No significant differences were found out between PFMI and pain episodes of myocardial ischemia in group I subjects. PST in both groups subjects was not associated with the number of damaged coronary arteries (CA) and presence of the asynergic zones in the left ventricle (LV). In angina-free subjects presenting with the single CA affection, the right coronary artery (RCA) appeared to be affected much more frequently than in those patients with stabile angina. No primary damage to RCA could be seen in associated CA afflictions.
