Implication

Supports hypertension control in aSAH prevention; extends demographic-specific associations but remains hypothesis-generating pending prospective validation.

Key Points

This study investigates the risk factors associated with aneurysmal subarachnoid hemorrhage (SAH) in Izumo City, Japan.
Conducted a case-control study of 247 patients with aneurysmal SAH between 1980 and 1998.
Assessed various risk factors including hypertension and smoking using conditional logistic regression.
Performed multivariate analysis to evaluate the strength of each risk factor after adjustment.
Hypertension was identified as the most powerful risk factor for SAH (OR higher in women).
Cigarette smoking was a significant risk factor in men aged 59 or younger.
Hypercholesterolemia was a notable risk factor in women aged 60 or older, while diabetes and heart disease showed an inverse relationship for older women.
