OBJECTIVE The purpose of this study was to examine the long-term mortality rate of patients with aneurysmal subarachnoid hemorrhage (SAH) compared with that of the general population. METHODS Aneurysmal SAH patients who were treated for ruptured aneurysm from 1977 through 1998 in a tertiary referral center (n=1537) were followed up for a median of 7.5 years. Dates and causes of death were determined. Standardized mortality ratios (observed/expected deaths) according to age, sex, and Glasgow Outcome Scale at 12 months after surgery were calculated. RESULTS The mortality rate among patients with good recovery at 12 months was twice that of the general population. The excess mortality appeared to be most evident in younger age groups. Cerebrovascular and cardiovascular diseases were the principal causes of premature death. The result was similar among patients without preexisting cardiovascular diseases at the time of SAH. CONCLUSIONS Aneurysmal SAH patients have an excess mortality rate even after successful treatment of ruptured aneurysms. Therefore, aneurysmal SAH should be viewed more as one aspect of a chronic general vascular disease, and more attention should be given to treatment of risk factors and long-term follow-up of these patients.
