Objective: To investigate the clinical characteristics and outcomes of overweight and obese patients with pulmonary embolism. Methods: This was a retrospective study of patients with pulmonary thromboembolism(PTE) in Beijing Hospital between 2009 and 2017. Data were analyzed and compared based on body mass index (BMI), and patients were classified into normal weight, overweight, and obese. Results: Among 372 patients with PTE, 159 were normal, 143 were overweight and 70 were obese. The mean age was (67.8±13.4) years, and 159(47.0%) were males. There was no significant difference in age, sex, smoking ratio, and underlying disease between the 3 groups (all P>0.05). Chest pain was less frequent in the obese group than the overweight group (P<0.05), and swollen of lower limbs was more prevalent in the obese group than the first 2 groups (all P<0.05). The levels of hemoglobin and hematocrit in the obese group were significantly higher than those in the normal group(P<0.05), while the serum uric acid levels were significantly higher than that in the normal group (P<0.05). Anticoagulation was more frequent in the overweight than the normal group(P<0.05) and Warfarin use was more frequent in the overweight and the obese than the normal group(both P<0.05). The mortality rate was higher in the normal group than those in the overweight and the obese groups (both P<0.01). Multiple logistic regression analysis after adjusting for age and sex showed that malignancy (OR=3.716, 95%CI: 1.733-7.972, P=0.001) and high risk PTE (OR=13.815, 95%CI: 4.093-46.624, P<0.001) were predictors of mortality, whereas anticoagulation (OR=0.155, 95%CI: 0.056-0.428, P<0.001), BMI≥24 (OR=0.142, 95%CI: 0.045-0.446, P=0.001) and BMI≥28 (OR=0.272, 95%CI: 0.085-0.872, P=0.029) were the predictors of survival. Conclusions: Proportion of hypertension, diabetes, coronary heart disease and hyperlipidemia were not significantly different in patients with overweight and obesity compared to patients with normal weight. Obese patients had higher levels of uric acid and hemoglobin than normal weight. Overweight and obese patients had a better survival.
