Study on the risk factors of rebleeding in subarachnoid hemorrhage

Objective To evaluate the risk factors of rebleeding in subarachnoid hemorrhage patients.Methods One hundred and sixty-eight patients who survived the subarachnoid hemorrhage were followed up for 6 months after the bleeding,which included 40 cases of rebleeding,128 cases of nonrebleeding.The risk factors were compared between the two groups.Results In the rebleeding patients,more patients had the risk factors as being over 60 years,hypertension,aneurysm,admission over 24 hours after the first attack,diabetes and drinking alcohol in the rebleeding patients,with a significant difference compared with nonrebleeding patients(P0.01).There was no significant difference in the other risk factors,as smoking,sex,heart disease and hyperlipidemia between two groups(P0.05).Conclusion Being over 60 years old,hypertension,aneurysm,admission over 24 hours after the first attack,diabetes and drinking alcohol were the risk factors in rebleeding insubarachnoid hemorrhage.
