本文比较了牡丹江、海林地区汉族与朝鲜族人群体循环血管阻力(systemic vascular resistance,SVR)差异及相关影响因素。采用BIOZ无创血流动力学心功能监护仪,检查了1647名汉族和876名朝鲜族人SVR、体循环血管阻力指数(systemicvascular resistance index,SVRI)、收缩压(systolic blood pressure,SBP)、舒张压(diastolic blood pressure,DBP)、平均动脉压(mean arterial pressure,MAP)、心输出量(cardiac output,CO)、心指数(cardiac output index,CI)和心率(heart rate,HR)。采用SPSS15.0软件统计分析所得数据。结果表明汉族人群男性和女性SVR/SVRI分别低于同性别、同年龄组朝鲜族人群。t检验比较两民族之间的差异,结果显示:(1)SVR存在统计学差异的组别有:男性41~50、51~60、61~70岁组(P<0.001),31~40岁组(P<0.01),19~30岁组(P<0.05);女性15~18、31~40、51~60岁组(P<0.001),41~50岁组(P<0.01),61~70岁组(P<0.05)。(2)SVRI存在统计学差异的组别有:男性41~50、51~60岁组(P<0.05);女性10~14、51~60岁组(P<0.001),15~18、31~40岁组(P<0.01),41~50岁组(P<0.05)。协方差分析表明,排除了性别、年龄、体重指数(body mass index,BMI)等因素的影响后,两民族之间SVR/SVRI仍然存在统计学差异(P<0.001)。多元线性回归显示:对两民族之间SVR差异影响的贡献大小依次为MAP、DBP、CI、SBP、HR;对SVRI差异的影响强弱依次为MAP、DBP、SBP、CI、HR。以上结果表明,SVR/SVRI的升高与朝鲜族血压高于汉族有关。
This article compares the differences of systemic vascular resistance (SVR) between Han and Korean ethnic groups in Mudanjiang and Hailin and the related factors. Using BIOZ non-invasive hemodynamic heart function monitor, SVR, systemic vascular resistance index (SVRI), systolic blood pressure (SBP), diastolic pressure (diastolic blood pressure) were examined in 1647 Han and 876 Korean nationals blood pressure (DBP), mean arterial pressure (MAP), cardiac output (CO), cardiac output index (CI) and heart rate (HR). Using SPSS15.0 software statistical analysis of the data. The results showed that the male and female Han Chinese SVR / SVRI were lower than the same age, the same age group Korean population. t-test to compare the differences between the two ethnic groups, the results showed that: (1) SVR there are statistically significant differences in the group were: male 41 ~ 50,51 ~ 60,61 to 70 years old group (P <0.001) (P <0.01), 19 ~ 30 years old group (P <0.05), female 15 ~ 18,31 ~ 40,51 ~ 60 years old group (P <0.001), 41 ~ 50 years old group ~ 70 years old group (P <0.05). (2) There were statistically significant differences between the groups of SVRI in 41-50, 51-60 years old men (P <0.05), 10-14, 51-60 years old women (P <0.001), 15-18,31 ~ 40 years old group (P <0.01), 41 ~ 50 years old group (P <0.05). Analysis of covariance showed that SVR / SVRI between the two ethnic groups remained statistically significant (P <0.001) after excluding the influence of gender, age, body mass index (BMI) and other factors. Multivariate linear regression analysis showed that the contributions of the two groups to the SVR differences were MAP, DBP, CI, SBP and HR, and the influence on the differences of SVRI were MAP, DBP, SBP, CI and HR in turn. The above results indicate that the rise of SVR / SVRI is related to the higher blood pressure of Han nationality than Han nationality.
