Objective To investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital to enrich the epidemiological data of chronic thromboembolic pulmonary hypertension (CTEPH) in China.
Methods We conducted a retrospective study to investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital from 2008 to 2012.
Results The incidence of CTEPH was 5.24% . About 62.90% of venous thromboembolism/pulmonary embolism (VTE/PE) patients were unprovoked, and about 53.85% of CTEPH patients was unprovoked. About 38% of CTEPH patients had no history of VTE, and 62% of CTEPH patients had no history of acute pulmonary embolism. None of the CTEPH patients was treated by pulmonary thromboendarterctom (PTE) , and about 53.85% of patients were only given anticoagulant monotherapy.
Conclusions The incidence of CTEPH is higher in our hospital than reported. This phenomenon may be related to the lack of awareness of risk factors of CTEPH and the insufficient thrombolytic and anticoagulant therapy to acute pulmonary embolism. It’s very urgent to standardize the diagnosis and management of CTEPH in pulmonologists.
