目的

探讨定量弹性成像(ElastPQ)定量评估慢性心力衰竭对肝脏产生的影响。

方法

收集分析解放军第三〇五医院2017年11月至2018年11月收治的58例中重度慢性心力衰竭患者的临床资料。依据《中国心力衰竭诊断和治疗指南2014》和患者基础资料将患者分组:左心衰组24例,男17例,女7例,年龄50~58岁;右心衰组14例,男9例,女5例,年龄43~85岁;全心衰组20例,男13例,女7例,年龄44~86岁。另取各项基础资料与病例组相匹配的30例健康志愿者为对照组(所有受检者之前均无肝脏疾病损害史)。所有受检者均用Elast PQ技术检测肝脏弹性模量值,行常规超声心动图等检查并记录相关参数,对各组间肝脏弹性模量值及其他相关参数进行统计学分析。

结果

与对照组相比,左心衰组的肝脏弹性模量值升高,右心衰组及全心衰组弹性模量值升高则更为显著[分别为(4.2±0.9)kPa、(6.1±0.8)kPa、(10.1±4.3)kPa、(12.3±4.8)kPa],组间差异均有统计学意义(t=0~0.004,均P<0.05);与左心衰组比较,右心衰组及全心衰组肝脏弹性模量值也升高明显,组间差异均有统计学意义(均P<0.05);与右心衰组比较,全心衰组弹性模量值也有升高,组间差异有统计学意义(t=0.033,P<0.05)。

结论

ElastPQ弹性成像技术可以定量地评价慢性心衰对肝脏产生的影响。中重度慢性心衰患者的肝脏弹性模量值普遍较正常人增高,以右心衰和全心衰增高最为显著,虽然左心衰患者肝脏的常规二维超声表现正常,但肝脏弹性模量值较正常人却仍有增高。

Objective

To evaluate the value of point quantitative elastography (ElastPQ) in the assessment of liver elastic modulus in patients with chronic heart failure (CHF).

Methods

This study included 58 patients with CHF who were treated at the PLA 305 Hospital from November 2017 to November 2018. According to the 2014 Chinese guidelines for the diagnosis and treatment of heart failure, these patients were divided into three groups: left heart failure (LHF) group, n=24 (17 males and 7 females, aged 50-58 years); right heart failure (RHF) group, n=14 (9 males and 5 females, aged 43-85 years); and whole heart failure (WHF) group, n=20 (13 males and 7 females, aged 44-86 years). In addition, 30 healthy volunteers whose basic data matched the case group were selected as controls (all had no previous history of liver injury). All subjects were tested by ElastPQ for liver elastic modulus. Routine echocardiography was performed and relevant parameters were recorded. The values of liver elastic modulus and other relevant parameters were statistically analyzed.

Results

Compared with the control group, the liver elastic modulus increased in the LHF group, and it was more significant in the RHF group and the WHF group [(4.2±0.9) kPa, (6.1±0.8)kPa, (10.1±4.3) kPa, and (12.3±4.8) kPa, respectively; t=0-0.004, P<0.05]. Compared with the LHF group, the elastic modulus of the RHF group and the WHF group increased significantly (P<0.05). Compared with the RHF group, the elastic modulus of the WHF group significantly increased (t=0.033, P<0.05).

Conclusions

ElastPQ can be used to quantify the impact of CHF on the liver. The liver elastic modulus of patients with moderate or severe CHF is generally higher than that inhealthy subjects, and the liver elastic modulus in RHF and WHF patients are the highest. Although routine echocardiography of the liver in patients with LHF is normal, the liver elastic modulus is still higher than that in healthy subjects.
