Abstract. Hypertensive crisis is one of the most serious complications of arterial hypertension and remains an important public health problem worldwide. Recent studies suggest that heliogeophysical factors, particularly geomagnetic storms, may influence cardiovascular function and increase the risk of adverse cardiovascular events. This study evaluates the impact of geomagnetic storms on the incidence of hypertensive crises in the Fergana region. The relationship between geomagnetic activity and hypertensive crisis occurrence was analyzed using clinical, epidemiological, and statistical methods. The findings demonstrated that periods of increased geomagnetic activity were associated with a higher frequency of hypertensive crises, especially among elderly individuals and patients with pre-existing cardiovascular diseases. A positive correlation was identified between geomagnetic disturbances and the incidence of hypertensive crises. The results emphasize the importance of considering environmental and heliogeophysical factors in cardiovascular risk assessment and preventive healthcare strategies. The study may contribute to the development of effective preventive measures and improved management of patients at high cardiovascular risk during periods of increased geomagnetic activity.
