Abstract

Background Idiopathic pulmonary fibrosis (IPF) is known as a particular pattern of persistent gradually developing fibrosing interstitial pneumonia of unspecified cause that takes place mainly in elder adults, is restricted to the lungs, and is correlated with the radiological and/or histopathological pattern of usual interstitial pneumonia. Patients with IPF exhibit characteristic features regarding the respiratory and cardiac muscle function. The lack of an association between diaphragmatic mobility and echocardiography findings of right and left ventricle functions in patients with IPF was unexpected as transthoracic ultrasound (US) and echocardiography are feasible, reproducible, noninvasive, and largely adopted in the clinical practice and in clinical trials. Objective To correlate between diaphragmatic mobility using transthoracic US and ventricular functions using echocardiography in patients with IPF. Patients and methods A prospective case–control study was conducted in which 40 patients with IPF and 10 controls underwent transthoracic US assessment of diaphragmatic excursion and echocardiography study, and then the results were correlated. Results There was a statistically significant decrease in deep breathing excursion, right ventricle functional area change, tricuspid annular plane systolic excursion, and ejection fraction in addition to an increase in pulmonary artery systolic pressure among the study group. Both normal breathing excursion and deep breathing excursion have a positive correlation with right ventricle functional area change and tricuspid annular plane systolic excursion, whereas a negative correlation was seen with age and pulmonary artery systolic pressure in both study and control groups. Conclusions Transthoracic US assessment of diaphragmatic mobility can clearly reflect the right ventricle function in patients with IPF.
特发性肺纤维化患者经胸超声膈肌活动度与超声心动图表现的相关性
特发性肺纤维化(IPF)是一种特殊类型的持续逐渐发展的原因不明的纤维化间质性肺炎,主要发生在老年人中,局限于肺部,与通常的间质性肺炎的影像学和/或组织病理学模式相关。IPF患者在呼吸和心肌功能方面表现出特征性特征。由于经胸超声(US)和超声心动图是可行的、可重复的、无创的,并且在临床实践和临床试验中广泛采用,因此在IPF患者中膈肌活动度与左右心室功能超声心动图结果之间缺乏相关性是出乎意料的。目的探讨IPF患者经胸超声心动图膈肌活动度与心室功能的相关性。患者与方法采用前瞻性病例对照研究方法,对40例IPF患者和10例对照者进行经胸超声心动图检查和膈肌漂移评估,并将结果进行相关性分析。结果实验组患者的深呼吸偏移、右心室功能面积变化、三尖瓣环平面收缩偏移、射血分数均显著降低,肺动脉收缩压升高。正常呼吸偏移和深呼吸偏移与右心室功能区变化和三尖瓣环平面收缩偏移呈正相关,而与年龄和肺动脉收缩压呈负相关。结论经胸超声测量膈肌活动度能清晰反映IPF患者的右心室功能。
