Abstract

No data have been published on the role of vascular risk factors for perimesencephalic nonaneurysmal subarachnoid hemorrhage (PMSAH). In a case-control study we compared the prevalence of vascular risk factors in 40 consecutive patients who suffered a perimesencephalic subarachnoid hemorrhage with that in two controls groups: (a) 120 subjects registered with a general practitioner (GP; matched at a 3 : 1 ratio for age and sex) and (b) 81 proxies of patients of a hospital outpatient clinic. A conditional multivariate logistic regression model was performed taking into account the matched design. Hypertension was more frequent among PMSAH patients than among the two control group subjects for men and women. Among women, smoking was more common in PMSAH than in the GP control group. The conditional multivariate logistic regression model confirmed that hypertension was an independent risk factor for PMSAH (P = 0.036) Hypertension is a preventable risk factor of PMSAH.
