Analysis of stroke risk factors and cerebrovascular hemodynamic indexes of Han nationality and major ethnic minorities in a tertiary hospital in southwest Yunnan / 中国脑血管病杂志

ABSTRACT

Objective To analyze the differences between the exposure levels of major stroke risk factors and cerebral vascular hemodynamic indexes (CVHIs) in Han nationality and major ethnic minorities in Pu'er People Hospital in southwest Yunnan. Methods In this cross-sectional study,26 640 patients admitted to Pu'er People Hospital for stroke risk assessment were recruited from July 2016 to September 2018. Major risk factors of stroke and CVHIs were investigated and detected. The subjects were divided into six ethnic groups,including Han, Yi, Hani, Dai, Lahu and Wa. The differences of the exposure rate of major stroke risk factors,CVHIs and cerebrovascular function scores among these ethnic groups were compared and analyzed. Results There were significant differences (all P < 0. 01) in the risk factors for stroke. Dai ethnic group had the highest prevalence of hypertension (34. 7% [194/559]) and Wa ethnic group the lowest (26. 3% [94/358]). Han ethnic group had the highest dyslipidemia rate of 7. 9% [1892/23887], and Dai ethnic group was 4. 3% [24/559] . The prevalence rate of diabetes among Lahu ethnic group was highest at 10. 1% [34/335] and Hani ethnic group lowest at 3.3% [30/907]. Among different ethnic groups, the minimum velocity, mean velocity, peripheral resistance, and cerebrovascular function scores were statistically significant (all P <0.05). The proportion of cerebrovascular function scores less than 75 points (stroke high-risk individual) in Han, Y i, Hani, Dai, Lahu, Wa ethnic group was respectively 36.7% [8 759/23 887],32.7% [194/594],34. 1% [309/907], 38. 3% [214/559], 31. 9% [107/335] and 32. 4% [116/358] (P < 0. 05) . Conclusions There were significant differences in the exposure levels of major stroke risk factors and CVHIs among ethnic groups in Pu'er People Hospital in southwest Yunnan. Han and Lahu ethnic groups had higher exposure level of risk factors. Cerebral vascular function damage was more serious in Han and Dai ethnic groups.
