目的探讨慢性阻塞性肺病(COPD)患者右室Tei指数与肺功能指标是否存在相关关系。方法回顾性分析了14例临床症状轻重程度不同的COPD患者,将这些病例经超声心动图测得的右室Tei指数分别与其肺功能指标:第1秒用力呼气量与用力肺活量比值(FEV1/FVC)、一氧化碳弥散度与预计值比值(DLCO/P)、氧分压(PaO2)、二氧化碳分压(PaCO2)进行直线相关性分析。结果14例COPD患者的右室Tei指数与FEV1/FVC呈高度负相关,r=-0.851,p<0.001;与DLCO/P呈中度负相关,r=-0.638,p<0.05;与PaCO2呈中度正相关,r=0.703,p<0.01,与PaO2的相关关系不明显,r=-0.345,p>0.05。结论COPD患者的心功能受损与肺功能受损存在相关性。右室Tei指数是反映右心功能较敏感的指标。
Objective To investigate the relationship between right ventricular Tei index and pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Methods A retrospective analysis of 14 patients with different severity of clinical symptoms of COPD patients, these cases were measured by echocardiography Tei index and their right lung ventricular function index: 1 second forced expiratory volume and forced vital capacity ratio (FEV1 / FVC, DLCO / P, PaO2 and PaCO2. Results The Tei index of right ventricle in COPD patients was negatively correlated with FEV1 / FVC (r = -0.851, p <0.001), moderate negative correlation with DLCO / P (r = -0.638, p <0.05) Moderate positive correlation, r = 0.703, p <0.01, and PaO2 was not related, r = -0.345, p> 0.05. Conclusion There is a correlation between impaired cardiac function and impaired lung function in patients with COPD. Right ventricular Tei index is a more sensitive index of right heart function.
