INFLUENCES OF GEOMAGNETIC DISTURBANCES ON CAPILLARY-FLOW IN PATIENTS WITH ISCHEMIC HEART-DISEASES

A total of 80 patients with ischemic heart diseases (men-47, women-33) were followed up daily during 2-3 weeks. We studied capillary flow in the cuticle above the nail (eponichium) with TV-capillaroscope, allow ed to conduct prolonged studies. We evaluated capillary indicies for p erivascular edema, erythrocytes aggregation, blood velocity. Microcirc ulations data were compared daily values of geomagnetic activity (A-in dex), three-hour-range indicies (K) and atmospheric pressure. In the f irst day magnetic storms pathological changes of capillar flow were de tected in 71,5% patients with acute miocardial infarction (men - 73,7% , women - 69,2%). We could see appearance of perivascular edema, red b lood cell aggregation, delay and slowing down capillary flow. Similar changes were detected in patient with angina pectoris in 64,8% (men -7 3,3%, women - 56,3%). Number patients with ischemic heart deseases rea cted upon geomagnetic disturbances exceed more then 2,5 times quantity patients, who react upon change of atmospheric pressure.
