原发性肺动脉高压(PPH)以肺血管阻力增加、肺动脉压升高为特征，常导致右心结构和功能异常。这些异常包括右室和右房扩张、右室收缩功能降低、室间隔移位和三尖瓣反流。(1-5)我们和其他人(1，5)也注意到PPH患者心包积液的发生率很高。在这篇文章中，我们报告了严重症状性PPH患者心包积液的大小与血流动力学、右心结构和功能、运动能力和生存的关系。
Primary pulmonary hypertension (PPH) is characterized by increased pulmonary vascular resistance and elevated pulmonary arterial pressure, which often result in abnormalities in right-sided heart structure and function. These abnormalities include right ventricular and right atrial dilatation, decreased right ventricular contractile function, displacement of the ventricular septum, and tricuspid regurgitation.(1-5) We and others(1,5) also noted a high prevalence of pericardial effusion in patients with PPH. In this article, we report the relations of pericardial effusion size to hemodynamics, right-sided heart structure and function, exercise capacity, and survival in patients with severely symptomatic PPH.
