肺部常为多种结缔组织病 ( CTD)累及 ,导致肺动脉高压( PAH)。以往多依赖于心导管检查作出诊断。本组资料采用脉冲多普勒超声心动图 ( PDE)检测肺动脉血流频谱评估 CTD肺高压 ,并探讨其影响因素。对象与方法1.对象 :经临床、血清学、X线或病理确诊的 CTD患者 5 1例 ,有完整的血
Pulmonary involvement is often associated with multiple connective tissue diseases (CTDs), leading to pulmonary hypertension (PAH). In the past mostly dependent on cardiac catheterization to make a diagnosis. This group of data using pulsed Doppler echocardiography (PDE) detection of pulmonary arterial blood flow spectrum to assess CTD pulmonary hypertension, and explore the influencing factors. Subjects and methods 1. Subjects: clinical, serological, X-ray or pathologically confirmed 51 cases of CTD patients with complete blood
