Stress as a Possible Factor Facilitating Subarachnoid Hemorrhage

The purpose of the study was to establish the possible environmental influences in the observed peculiar rising and falling oscillations in the numbers of SAH in Eastern Croatia (region of Osijek) during the last eleven-years' period. Although the great local and regional differences have been established in the incidence of spontaneous SAH in the general population, longitudinal analyses of the annual incidence and mortality rates of SAH did not show the declining tendency, differently to other forms of stroke. In some previous studies various environmental factors have been suspected to influence the circadian or circannual patterns of SAH occurrence. Among the 5881 patients treated for Stroke in the eleven year� s period (1988-1998) we have specifically analyzed the 160 patients diagnosed as Subarachnoid Hemorrhage (SAH) for the observed variations in the period. These variations disclosed a correlation with heavy living conditions during the recent war. During the war-period the SAH incidence sharply rose. Immediately after the war it suddenly decreased: the authors named this phenomenon a "pool depletion", supposing the relatively stable proportion of the bearers of aneurysms in a population. The observed variations could be best explained as the consequences of the War Stress. The stress increases the risk for SAH through complex pathophysiological mechanisms. The female sex is according to our observations a risk factor for SAH, too.
