Space weather and hypertensive crises at high Latitudes (in Yakutsk)

Abstract

The space weather impact on the health status of people with cardiovascular diseases is quite significant and it has been shown by many researchers. To examine this relationship at high latitudes, we made a Yakutsk ambulance electronic database analysis. The significant coincidences of geomagnetic disturbance indicators (Kp-index - a global geophysical disturbance index) and the increased blood pressure emergency calls number have been determined during the high solar activity years. The blood pressure increase cases analysis shows that patients with primary essential arterial hypertension (AH) seek medical help in 57%. Furthermore, 7% of AH patients experienced a hypertensive crisis (HC) with an increase in systolic blood pressure (SBP) from 180 mm Hg, diastolic blood pressure (DBP) from 120 mm Hg. The medical data analysis and the space weather data (Kp-index) comparison demonstrate a significant coincidence, which became the main base for the conclusion that heliogeophysical disturbance effects on the cardiovascular system state of a person living at high latitudes.
