【摘要】：【目的】为制定中国成年人肺动脉收缩压参考值的统一标准提供科学依据。【方法】搜集了中国61个地区的3 405例健康成年人肺动脉收缩压参考值资料,运用相关分析研究肺动脉收缩压与7项地理指标的关系,利用向后回归分析和因子分析分别建立了模型并利用T检验对最优模型进行选取。【结果】肺动脉收缩压与地理指标存在显著的相关性。经验证,因子分析模型为最优预测模型。根据模型计算全国2 322个地区的PASP预测值,利用Arc GIS软件的克里金插值法内插出中国成年人肺动脉收缩压度参考值的空间趋势分布图。【结论】海拔是成年人肺动脉收缩压参考值最主要的影响因子。若已知中国某地的地理指标数据,可通过因子分析模型计算得出结果,也可利用空间趋势图直观地得到中国任何地区的成年人肺动脉收缩压参考值。
[Abstract]:[objective] to provide a scientific basis for establishing a unified standard for the reference value of pulmonary artery systolic pressure in Chinese adults. [methods] the reference data of pulmonary artery systolic blood pressure of 3 405 healthy adults from 61 regions of China were collected. Correlation analysis was used to study the relationship between pulmonary artery systolic pressure and 7 geographic indexes. The model was established by backward regression analysis and factor analysis, and the optimal model was selected by T test. [results] there was a significant correlation between pulmonary artery systolic pressure and geographic index. The factor analysis model is the optimal prediction model. According to the model, the PASP prediction values of 2 322 regions in China are calculated. Using the Kriging interpolation method of Arc GIS software, the spatial trend distribution of the reference value of pulmonary artery systolic pressure in Chinese adults is interpolated. [conclusion] altitude is the most important factor affecting the reference value of pulmonary artery systolic pressure in adults. Geographical indicators of a place in China, The results can be calculated by factor analysis model and the reference values of pulmonary artery systolic pressure of adults in any region of China can be obtained intuitively by using spatial trend map.
