Pulmonary Artery Involvement in Takayasu's Arteritis

Completed

• Conditions: Pulmonary Artery Hypertension; Takayasu Arteritis

• Registration Number: NCT03189602
• Lead Sponsor: Peking Union Medical College Hospital

Brief Summary

The purpose of this study is to analyze the clinical manifestations, imaging features, and prognosis-related factors of pulmonary artery (PA) involvement in Takayasu's arteritis (TA), and to explore the early clinical features of PA involvement in TA patients.

Detailed Description

Takayasu's arteritis patients with pulmonary artery involvement were enrolled into this study. The demographic information of the patients (age, sex, course of disease), symptoms at their admissions (cough, hemoptysis, dyspnea, palpitations, fever), laboratory examinations (blood lab routines, erythrocyte sedimentation rate, C-reactive protein), and imaging examinations (vascular ultrasonography, computed tomographic angiography, echocardiography, chest CT, CTPA, pulmonary perfusion imaging, pulmonary angiography, PET/CT) were collected by reviewing the cases. The prognostic information was collected by telephone follow-up. The follow-up end point was December 2015.
