摘　　要：目的明确各因素对肺动脉高血压患者右室收缩后收缩现象的关联程度,找出影响收缩后收缩的主要因素。方法采用灰色关联分析方法,对10例肺动脉高血压患者体检资料进行统计分析,确定各项影响因素与收缩后收缩的关联程度。结果肺动脉高血压患者右室收缩后收缩现象影响因素的关联度依次为,右室前壁厚度>右室舒张功能指数>游离壁中段舒张期应变率>右室横径>心率>游离壁中段收缩期应变率>肺动脉收缩压。结论影响收缩后收缩的主要因素是右室前壁厚度。Objective To make clear the correlation between various influencing factors and right ventricle postsystolic shortening （PSS） of patients with pulmonary artery hypertension, and to find the main influencing factors. Methods The Grey incidence analysis was used to determine the correlation degree of various factors with PSS according to the statistical analysis of physical examination in 10 patients with pulmonany artery hypertension. Results The correlation degree of various factors related to PSS was as follows：right ventricular anterior wall thickness 〉 right ventricular Tei index 〉 early diastolic strain rate 〉 fight ventricular transverse diameter 〉 heart rate 〉 peak systolic strain rate 〉 pulmonary arterial systolic pressure. Conclusion Right ventricular wall thickness is the main factor influencing PSS.
