[Lipids metabolism of the patients with subarachnoid hemorrhage due to ruptured intracranial aneurysm, in comparison with other cerebrovascular diseases].

Lipids metabolism has been extensively studied in the large number of patients with hypertensive cerebral hemorrhage or cerebral infarction, however, the patients with subarachnoid hemorrhage due to ruptured intracranial aneurysm were customarily excluded from the study. Total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride and atherogenic index were determined in 40 cases, who had undergone surgical treatment for ruptured intracranial aneurysm in various locations, and the results were compared with the data obtained from 20 operative cases with hypertensive cerebral hemorrhage, 40 cases with non-operative cases with hypertensive cerebral hemorrhage, 60 cases with cerebral infarction and 20 cases of cerebral lesions other than cerebrovascular disease (non-CVA). Serum levels of LDL-cholesterol and atherogenic index were significantly correlated with the preoperative grading of subarachnoid hemorrhage when compared with non-CVA (p less than 0.05). Total cholesterol, LDL-cholesterol and atherogenic index were well correlated with operative morbidity and active daily life (ADL) in the follow-up study of the patients with intracranial aneurysm, where the higher value of cholesterol indicated the poorer risk of the patients. In our present study, none of the data was found significant, when compared with non-CVA, in the other groups of cerebrovascular diseases except for the HDL-cholesterol, which was found significantly in low level in the group of cerebral infarction (p less than 0.001). Triglyceride was found elevated in the group of hypertensive hemorrhage indicating negative correlation to the severity, and rather similar pattern was seen in the subarachnoid hemorrhage, however, the data were not conclusive.(ABSTRACT TRUNCATED AT 250 WORDS)
