摘　　要：目的:研究大面积肺栓塞(MPE)患者CT肺动脉栓塞指数(PAOI)与心血管参数的相关性。方法:选择医院收治的80例MPE患者,根据病情严重程度将其分为危重组(28例)和非危重组(52例),比较两组PAOI、主肺动脉最大直径(MPAd)、MPAd与升主动脉直径比值(rPA)、右心室短轴最大径(RVd)、左心室短轴最大径(LVd)以及RVd与LVd比值(RVd/LVd),应用Pearson相关性分析MPE患者CT PAOI与心血管参数的关系。结果:危重组的PAOI、MPAd、rPA、RVd及RVd/LVd显著高于非危重组,差异均有统计学意义(t=18.542,t=7.053,t=6.015,t=7.340,t=8.648;P<0.05);危重组的LVd显著低于非危重组,差异有统计学意义(t=5.650,P<0.05)。经Pearson相关性分析,MPE患者的MPAd、rPA、RVd、RVd/LVd与CT PAOI均呈正相关(r=0.493,r=0.542,r=0.595,r=0.619;P<0.05);MPE患者的LVd与CTPAOI呈负相关(r=-0.521,P<0.05)。结论:MPE患者CT PAOI与心血管参数有显著相关性,可及时评估MPE患者的肺栓塞、血流动力学变化情况,为临床治疗及预后改善提供支持。Objective:To study the relationship between computed tomography(CT)pulmonary artery obstruction index(PAOI)and cardiovascular parameters in patients with massive pulmonary embolism(MPE).Methods:Eighty patients with MPE were selected as the study subjects.They were divided into critical group(28 cases)and noncritical group(52 cases)according to the severity degree of the disease.The PAOI,the maximum main pulmonary artery diameter(MPAd),the ratio of the MPAd to the diameter of the ascending aorta(rPA),the maximum diameter of the short sleeve of the right ventricle(RVd),the maximum diameter of the short sleeve of the left ventricle(LVd)and the ratio of RVd to LVd between the two groups were compared.Pearson correlation analysis was used to analyze the relationship between CT PAOI and cardiovascular parameters in MPE patients.Results:The PAOI,MPAd,rPA,RVd,RVd/LVd of critical group were significantly higher than those of non-critical group(t=18.542,t=7.053,t=6.015,t=7.340,t=8.648,P<0.05),respectively.And the LVd of critical group was significantly lower than that of non-critical group(t=5.650,P<0.05).The results of Pearson correlation analysis indicated that MPAd,rPA,RVd,RVd/LVd were positively correlated with CT PAOI in MPE patients(r=0.493,r=0.542,r=0.595,r=0.619,P<0.05),and LVd was negatively correlated with CT PAOI in them(r=-0.521,P<0.05).Conclusion:There is a significant correlation between CT PAOI and cardiovascular parameters in MPE patients,which can timely assess the changes of pulmonary embolism and hemodynamics in MPE patients and provide support for clinical treatment and prognostic improvement.
