[Natural history of spontaneous subarachnoid hemorrhage. A 1-7 year follow-up study of 74 cases].
74 cases of spontaneous subarachnoid hemorrhage (SAH) were followed up for a period of 1 to 7 years, most of them had been examined by CT-scan and/or cerebral angiography. The life-table method was used to determine the cumulative survival rate and cumulative recurrence rate. The mortality rates in both acute and chronic stages and the re-bleeding rate were found to be essentially similar to those of other series of SAH admitted to a tertiary care center as were reported in the Chinese and world literature. Hypertension was probably a risk factor for SAH. The incidence of diabetes mellitus in the present series was significantly higher than that found in the same age groups of general population in Shanghai, which fact deserves further evaluation. The clinical characteristics of the patients in the acute stage were not found to be related to their outcome.
