由于慢性阻塞性肺疾病(慢阻肺)的不完全可逆性,对慢阻肺患者的疾病发展作出早期预测,提高防护,阻止它很快地进入呼吸系统衰竭状况便尤为重要。长期以来,慢阻肺疾病诊断的主要客观辅助检查仅有肺功能检查。本研究主要是通过对慢阻肺患者肺功能分级与右心功能指标的相关性进行研究,找出相关性较强的右心功能指标,运用肺功能检查和超声心动检查结合的方式对慢阻肺患者的状态进行量化评估,开辟慢阻肺疾病早期预测和治疗的新 Due to the incomplete reversibility of chronic obstructive pulmonary disease (COPD), it is especially important to predict early disease progression in COPD patients and improve protection and prevent it from quickly entering respiratory failure. For a long time, the main objective auxiliary examinations for the diagnosis of COPD have only pulmonary function tests. In this study, we mainly studied the correlation between COPD and right heart function in patients with COPD, and found the right cardiac function indexes with strong correlation. By using the combination of pulmonary function test and echocardiography, Pulmonary patients to quantify the status assessment to open up the early prediction and treatment of chronic obstructive pulmonary disease
