摘要
目的采用超声心动图评价肺动脉压正常的慢性肝病患者(CLD)右心形态和功能的变化情况。方法纳入102例肺动脉压正常的CLD患者作为研究组,纳入50例年龄和性别与研究组匹配的受试者作为对照组。采用超声心动图评价其右心室(RV)和右心房(RA)大小、RV收缩/舒张功能指标以及心肌应变。结果与对照组比较,CLD患者的RV和RA大小、RV收缩/舒张功能指标以及心肌应变表现差异无统计学意义(P>0.05),而CLD患者的RV游离壁厚度大于对照组,差异有统计学意义(P<0.05)。CLD患者RV舒张末期直径和RA面积与RV游离壁厚度呈正相关(P<0.05)。结论肺动脉压正常的CLD患者,其RV游离壁的厚度可能增加,肝硬化性心肌病可能不会导致其RV收缩或舒张功能的受损。
Objective The changes of right heart morphology and function in patients with chronic liver disease(CLD with normal pulmonary artery pressure were evaluated by echocardiography.Methods A total of 102 CLD patients with normal pulmonary artery pressure were included as study group,and 50 subjects whose age and gender matched the study group were included as a control group.Echocardiography was used to evaluate right ventricular(RV)and right atrial(RA)size,RV systolic/diastolic function,and myocardial strain.Results Compared with the control group,the RV and RA size,RV systolic/diastolic function index and myocardial strain were similar in the CLD patients(P>0.05),while the RV free wall thickness in the CLD patients was higher than that in the control group(P<0.05).RV end-diastolic diameter and RA area were positively correlated with RV free wall thickness in patients with CLD(P<0.05).Conclusion In CLD patients with normal pulmonary arterial pressure,the thickness of the RV free wall may increase,and cirrhotic cardiomyopathy may not cause damage to its RV contraction or diastolic function.
