ABSTRACT
Objective To register the inpatients with stroke in Lasa plateau region,understand the clinical characteristics,risk factors and prognosis of patients with stroke in plateau region,and provide reference for prevention and treatment of stroke in plateau region.Methods Hospital-based stroke registration database was established,follow-up visits were paid to registered patients with stroke;the general sociological characteristics,clinical features,diagnosis and treatment situations of patients were collected and analyzed.Results Continuous registration in 464 patients with stroke in Tibet Autonomous Region People' s Hospital was made from July 1,2007 to March 30,2013,including 332 Tibetan patients and 132 Han patients,whose average age was (57.45 ± 16.14) years;326 male patients,138 female patients.Sixty-eight patients' age of onset was smaller than 40 years (14.22％).Among stroke subtypes,cerebral infarction was the most frequent syndrome (322 patients (69.40％)),followed by brain hemorrhage (129 patients (27.80％)),subarachnoid hemorrhage (13 patients (2.80％)).The difference between the male to female ratio of Tibetan patients (213:119) and Han patients(113:19) was statistically significant (x2 =20.795,P ＜0.001).The 4.5 h clinic visit rate of patients with stroke was 18.53％ (86/464),the 4.5 h clinic visit rate of patients with cerebral infarction was 13.35％ (43/322),including 1 patient who took intravenous thrombolytic therapy,accounting for 0.31％ of patients with cerebral infarction.The analysis indicated that the major risk factors of this group of patients with stroke were high blood pressure (249 patients (53.66％)),heart disease (102 patients (21.98％)),diabetes (67 patients (14.43％)) and chronic high altitude polycythemia (65 patients (14.00％)).Conclusions The patients with stroke in plateau regions tend to be younger,the clinic visit rate within 4.5 h is low,and the application of intravenous thrombolysis in patients with cerebral infarction is low.Chronic high altitude polycythemia becomes the special risk factor in plateau region.
