Abstract:
Objective To analyze basic data and outcomes in Chengdu Stroke Registry.Methods The stroke patients consecutively admitted to Department of Neurology,West China Hospital,Sichuan University since March 1,2002 were prospectively registered.The baseline demographic,risk factors,treatment,and outcome data was recorded with standardized stroke register form by trained specialists.The patients were followed up at seven days,one,three,six months and one year after onset of the stroke for death and disability.Results A total of 3123 consecutive patients were registered between March 1,2002 and August 31,2006,of which 65.5％ came from urban areas and 34.5％ from rural areas.The age was (63.05 ± 17.98) years old and male accounted for 60.3％.Ninety-seven percent (3028/3123) of patients completed CT or MRI scanning during hospitalization.A total of 1804 patients were included between March 2002 and September 2004,of which ischemic stroke accounted for 62.1％ (1120/1804),intracranial hemorrhage 28.4％ (513/1804),subarachnoid hemorrhage 4.0％ (72/1804) and TIA 5.5％ (99/1804).The median NIHSS score on admission was 8(3-15) points in patients with cerebral hemorrhage,and 5(2-10) points in patients with ischemic stroke.Compared with the patients with intracranial hemorrhage,patients with ischemic stroke more frequently had a history of diabetes (OR =2.427,95％ CI 1.811- 3.253,P=0.000),atrial fibrillation (OR=6.121,95％ CI3.535-10.60,P=0.000),coronary heart disease (OR=4.144,95％ CI 2.944-5.832,P =0.000) and TIA (OR=4.342,95％ CI 1.726-10.92,P =0.001 ),and less alcohol consumption ( OR =0.740,95％ CI 0.611-0.896,P =0.002 ).The proportion of in-hospital treatments were thrombolysis 0.9％,anti-platelet therapy 83.0％,mannitol 23.5％,neuroprotective agents (citicoline) 68.1％,and Chinese herbal medicine 89.7％.Case fatality rate was 10.7％ and 13.9％ respectively at 7 days and one month for patients with intracranial hemorrhage,3.0％ and 5.2％ respectively for ischemic stroke.Death or disability was 40.4％,40.3％ and 38.9％ in patients with intracranial hemorrhage and 37.1％,35.0％ and 33.4％ for ischemic stroke at the end of 3,6,12 months respectively.Conclusions Our stroke registry is featured with the largest sample,and the longest period of consecutively registration.It provides an important platform for clinical investigation of stroke.Our study suggested case fatality and disability is lower in this group than in other ethics.Above features should be considered in design of future clinical trials in China.
