Objective To measure and analyze cardiac ventricular sizes of acute pulmonary embolism patients,and compared with normal group,to investigate the morphological changes of heart in patients with acute pulmonary embolism.Methods 75 patients with acute pulmonary embolism were analyzed retrospectively and were divided into two groups according to the score of embolism index:more than or equal to 50% (group c,33 cases) and less than 50% (group b,42cases) and compared with normal group (group a,56 cases) to analyze the changes of cardiac ventricular transversal diameter(LR) and anteroposterior diameter (AP).Results The group c compared with group a and b,the right ventricular LR and AP,and the right atrium LR increased significantly (P<0.05),the left ventricular LR decreased significantly (P<0.05).The group b compared with the group a,the right ventricular LR and the right atrium AP increased significantly (P<0.05),the left atrium LR decreased significantly (P<0.05).The left atrial AP,group b was larger than that of group a and group c (P<0.05).The left ventricular AP,there was no significant difference between the three groups.The atrial ratio (RA/LA) and the ventricle ratio (RV/LV)of the three groups were significantly different (P<0.05).According to the product of two lines of the same heart cavity (RL × AP),compared with group a and b,the left atrium and ventricle of group c decreased (P<0.05),the right atrium and ventricle enlarged (P<0.05).Compared with group a,the left ventricular angle of group c decreased significantly (88.97±5.47 vs 97.91±7.66,P<0.001),there was no significant difference between the group b and c (P>0.05).After the treatment of acute pulmonary embolism,the right ventricular RL × AP is significantly reduced(4 209.57±844.63 vs 5 090.58±1312.69,P=-0.002),the ventricle ratio (RV/LV) is significantly reduced(0.80±0.13 vs 0.93±-0.19,P=0.003.Conclusions The size and shape of heart cavity varied with different pulmonary embolism index,and we can make preliminary observation and evaluate treatment efficacy by using chest CT scan.
