The data showed that geomagnetic field disturbances worsened microcirculation and arterial baroreflex sensitivity. The decrease in baroreflex sensitivity was significantly larger compared with microcirculation suggesting that changes in the geomagnetic field at first attenuates arterial baroreflex vascular control mechanism leading to a reduction in microcirculation. No significant correlation was found between geomagnetic disturbance and arterial blood pressure.
The authors recommended on days with intense geomagnetic activities to intensify the therapy of ischaemic cerebral and heart disease in order to meliorate microcirculation in brain tissue and myocardium.
