[Analysis of factors associated with pulmonary embolism during pregnancy]

To investigate risk factors associated with pulmonary embolism in women during pregnancy or peripartum. Information of 7 pregnant women diagnosed pulmonary embolism (PE) were collected from January 2018 to December 2020 in Beijing Friendship Hospital. Four non-PE pregnant women as control group were matched with each patient by age, BMI and pregnancy complications during the same period. Binary logistic regression was used to identify the potential risk factors by the comparison of difference between groups. The laboratory indices, including platelet, hemoglobin, prothrombin time, partially activated prothrombin time, D-dimer, triglyceride, total cholesterol, low density lipoprotein (LDL) and high density lipoproteinage (HDL) showed no significant difference between groups. D-dimer and HDL were found to be associated with PE during pregnancy (P<0.05). D-dimer and HDL might be associated with PE during pregnancy.
