Introduction. There are no studies investigating populations of patients with both pulmonary embolism and chronic obstructive pulmonary disease (PE-COPD) with and without deep venous thrombosis (DVT). Aim of the study. To define the prevalence of DVT in COPD with PE and to compare the characteristics of COPD patients who develop PE, with and without DVT. Secondly, we aimed to assess differences in the localization of PE among study groups. Methods. 116 patients with pulmonary embolism (PE) were enrolled in a retrospective study. Clinical data as well as echocardiographic and lower limb ultrasonography records were collected for all subjects. Subjects were divided into two groups according to the presence of COPD: Group 1, 54 patients with diagnosis of PE without COPD and Group 2, 66 patients diagnosed of PE with COPD. Then, individuals of Group 2 were subdivided in two subgroups according to the presence (n=21) or absence (n=45) of DVT. Results. 33% of patients with COPD and PE showed DVT. These subjects had higher PaCO2 and ejection fraction (p<0.05 for all) and higher percentage of chronic renal failure and diabetes mellitus compared to those without DVT (p<0.05 for all). Moreover, in COPD-PE patients with DVT, the most frequent localization was proximal (54% of total), whereas COPD-PE patients without DVT showed a more frequent segmental localization (60% of total). No difference was found in clinical presenta-tion and blood chemistry tests. Conclusions. DVT was non common in PE-COPD patients. Chronic renal failure, and type 2 diabetes mellitus are more frequent in PE-COPD patients with DVT, that showed a higher frequency of proximal localization, thereby indicating a greater risk of more severe clinical implications. Conversely, PE-COPD subjects without DVT showed a more frequent segmental localization and were less hypercapnic. PE should be taken into account in COPD with worsening of respiratory symptoms, also in absence of DVT. (www.actabiomedica.it).

Abstract

Introduction. There are no studies investigating populations of patients with both pulmonary embolism and chronic obstructive pulmonary disease (PE-COPD) with and without deep venous thrombosis (DVT). Aim of the study. To define the prevalence of DVT in COPD with PE and to compare the characteristics of COPD patients who develop PE, with and without DVT. Secondly, we aimed to assess differences in the localization of PE among study groups. Methods. 116 patients with pulmonary embolism (PE) were enrolled in a retrospective study. Clinical data as well as echocardiographic and lower limb ultrasonography records were collected for all subjects. Subjects were divided into two groups according to the presence of COPD: Group 1, 54 patients with diagnosis of PE without COPD and Group 2, 66 patients diagnosed of PE with COPD. Then, individuals of Group 2 were subdivided in two subgroups according to the presence (n=21) or absence (n=45) of DVT. Results. 33% of patients with COPD and PE showed DVT. These subjects had higher PaCO2 and ejection fraction (p<0.05 for all) and higher percentage of chronic renal failure and diabetes mellitus compared to those without DVT (p<0.05 for all). Moreover, in COPD-PE patients with DVT, the most frequent localization was proximal (54% of total), whereas COPD-PE patients without DVT showed a more frequent segmental localization (60% of total). No difference was found in clinical presenta-tion and blood chemistry tests. Conclusions. DVT was non common in PE-COPD patients. Chronic renal failure, and type 2 diabetes mellitus are more frequent in PE-COPD patients with DVT, that showed a higher frequency of proximal localization, thereby indicating a greater risk of more severe clinical implications. Conversely, PE-COPD subjects without DVT showed a more frequent segmental localization and were less hypercapnic. PE should be taken into account in COPD with worsening of respiratory symptoms, also in absence of DVT. (www.actabiomedica.it).
