系统性硬化症(systemic sclerosis,SSc)患者发生运动性肺高血压(exercise-induced pulmonary hypertension,exPH)的病因仍然是一个复杂的难题,因为左心室舒张功能受损和肺血管疾病都可促进其发展。该研究旨在确定SSc患者exPH的发生率,探讨肺动脉收缩压(pulmonary artery systolic pressure,PASP)和通过组织多普勒检测的肺毛细血管楔压(pulmonary
The etiology of exercise-induced pulmonary hypertension (exPH) in patients with systemic sclerosis (SSc) remains a complex problem because impaired left ventricular diastolic function and pulmonary vascular disease can promote its development of. The aim of this study was to determine the incidence of exPH in patients with SSc and to investigate the effects of pulmonary artery systolic pressure (PASP) and pulmonary capillary wedge pressure (pulmonary capillary wedge pressure
