Clinical Characteristics of Aneurysm Rupture with the Focus of Hypertension and Smoking as Predisposing Factors

Abstract

OBJECTIVE: The purpose of this study is to identify risk factors for subarachnoid hemorrhage(SAH) in Korea. METHODS: The clinical record and environmental data of 250 patients who had admitted our hospital between September 2001 and May 2003 were reviewed retrospectively by the neurosurgical nursing practitioners. RESULTS: In this study, the peak age for presentation with ruptured intracranial aneurysm was around 5th decade which is most active period of his or her life. The peak time of aneurysm rupture was from 6 to 12 A.M.(34.8%) and the onset of SAH occurred the most frequently at work(30.4%). The prevalence of hypertension in SAH patients was 42.8%, That of cigarette smoking in men and in women were 81.7% and 15.8% respectively. Hypertension was significantly corrected with the amount of hemorrhage based on Fisher Grading system (P<0.05). The consumption of smoking and the amount of hemorrhage was closely correlated also(P<0.05). CONCLUSION : Hypertension and cigarette smoking may be closely related to aneurysmal SAH. Undoubtedly, they are significantly related to massive, fatal SAH with poor neurologic condition. To prevent reduce aneurysmal SAH, cessation of smoking, anti-hypertensive medication and stress control are most important basic step in promotion of public health.
