[The effect of geomagnetic disturbances in capillary blood flow in ischemic heart disease patients].
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, allowed to conduct prolonged studies. We evaluated capillary indices for perivascular edema, erythrocytes aggregation, blood velocity. Microcirculations data were compared daily values of geomagnetic activity (A-index), three-hour-range indices (K) and atmospheric pressure. In the first day magnetic storms pathological changes of capillary flow were detected in 71.5% patients with acute myocardial infarction (men-73.7%, women-69.2%). We could see appearance of perivascular edema, red blood cell aggregation, delay and slowing down capillary flow. Similar changes were detected in patient with angina pectoris in 64.8% (men-73.3%, women-56.3%). Number patients with ischemic heart diseases reacted upon geomagnetic disturbances exceed more then 2.5 times quantity patients, who react upon change of atmospheric pressure.
