: Cardiovascular involvement in severe cirrhosis presents diagnostic challenges and carries significant prognostic implications. This study aims to evaluate the relationship between liver disease severity and portal hypertension with the burden of diastolic dysfunction. : We prospectively enrolled patients with hepatic cirrhosis, classified according to the Child-Pugh criteria. Of the 102 patients included, 65 were classified as Group A (non-severe cirrhosis: Child-Pugh Classes A and B) and 37 as Group B (severe cirrhosis: Child-Pugh Class C). Portal vein and spleen diameters were assessed using abdominal ultrasound. All patients underwent echocardiographic evaluation. LV systolic function was assessed by measuring ejection fraction, while diastolic function was evaluated using three parameters: E/Em ratio, E/Vp ratio, and indexed left atrial volume. : We observed a significantly greater burden of diastolic dysfunction in Group B compared to Group A. Specifically, the E/Vp ratio was 2.2 ± 0.4 in Group B versus 1.9 ± 0.3 in Group A ( < 0.001); the indexed LA volume was 34.5 ± 3.2 mL/m in Group B versus 30.1 ± 2.9 mL/m in Group A ( < 0.001); and the E/Em ratio was 17.0 ± 3.0 in Group B versus 11.5 ± 2.8 in Group A ( < 0.001). Additionally, the mean diameters of the portal vein and spleen were larger in Group B, with measurements of 14.3 ± 2.1 mm versus 11.5 ± 1.6 mm for the portal vein and 15.0 ± 1.2 mm versus 11.7 ± 1.5 mm for the spleen ( < 0.001), which correlated with the extent of diastolic dysfunction. : Diastolic dysfunction was prevalent in 55% of patients with liver cirrhosis. The burden of diastolic dysfunction was higher in patients with severe hepatic cirrhosis compared to those with milder forms, and it correlated with the severity of portal hypertension, as assessed by measuring portal vein diameter and spleen diameter.
重度肝硬化患者的心血管受累情况带来了诊断挑战,并具有重大的预后意义。本研究旨在评估肝病严重程度和门静脉高压与舒张功能障碍负担之间的关系。我们前瞻性纳入了根据Child-Pugh标准分类的肝硬化患者。在纳入的102例患者中,65例被归类为A组(非重度肝硬化:Child-Pugh A级和B级),37例被归类为B组(重度肝硬化:Child-Pugh C级)。使用腹部超声评估门静脉和脾脏直径。所有患者均接受超声心动图评估。通过测量射血分数评估左心室收缩功能,同时使用三个参数评估舒张功能:E/Em比值、E/Vp比值和左心房容积指数。与A组相比,我们观察到B组舒张功能障碍的负担明显更重。具体而言,B组的E/Vp比值为2.2±0.4,而A组为1.9±0.3(<0.001);B组的左心房容积指数为34.5±3.2 mL/m,而A组为30.1±2.9 mL/m(<0.001);B组的E/Em比值为17.0±3.0,而A组为11.5±2.8(<0.001)。此外,B组门静脉和脾脏的平均直径更大,门静脉测量值为14.3±2.1 mm,而A组为11.5±1.6 mm,脾脏测量值为15.0±1.2 mm,而A组为11.7±1.5 mm(<0.001),这与舒张功能障碍的程度相关。55%的肝硬化患者存在舒张功能障碍。与轻度肝硬化患者相比,重度肝硬化患者舒张功能障碍的负担更高,并且与通过测量门静脉直径和脾脏直径评估的门静脉高压严重程度相关。
