The diagnostic criteria for cirrhotic cardiomyopathy (CCM) were recently revised to reflect the contemporary advancements in echocardiographic technology. This study evaluates the prevalence of CCM, according to the new criteria, and its impact on posttransplant cardiovascular disease (CVD). This is a single-center retrospective matched cohort study of liver transplantation (LT) recipients who underwent LT between January 1, 2008 and November 30, 2017. A total of 3 cohorts with decompensated cirrhosis (nonalcoholic steatohepatitis, alcohol-related liver disease, or other etiologies) were matched based on age, sex, and year of transplant after excluding patients listed without evidence of hepatic decompensation. CCM was defined, according to 2020 criteria, as having diastolic dysfunction, left ventricular ejection fraction ≤50%, and/or a global longitudinal strain (GLS) absolute value <18%. The study echocardiographers were blinded to the clinical data. Posttransplant CVD included new coronary artery disease, congestive heart failure, atrial and ventricular arrhythmia, and stroke. The study included 141 patients of whom 59 were women. The mean age at LT was 57.8 (±7.6) years. A total of 49 patients (34.8%) had CCM. Patients with CCM were at an increased risk for post-LT CVD (hazard ratio, 2.57; 95% confidence interval, 1.2-5.5; P = 0.016). Changes in CCM individual parameters pretransplant, such as GLS, early diastolic transmitral flow to early diastolic mitral annular velocity, and left atrial volume index were associated with an increased risk for posttransplant CVD. CCM, defined by the new diagnostic criteria, affects approximately one-third of decompensated LT candidates. CCM predicts an increased risk for new CVD following LT. Studies into addressing and follow-up to mitigate these risks are needed.
肝硬化性心肌病(CCM)的诊断标准最近进行了修订,以反映超声心动图技术的当代进展。本研究根据新标准评估了 CCM 的患病率及其对移植后心血管疾病(CVD)的影响。这是一项单中心回顾性匹配队列研究,纳入了 2008 年 1 月 1 日至 2017 年 11 月 30 日期间接受肝移植(LT)的 LT 受者。共有 3 个失代偿性肝硬化(非酒精性脂肪性肝炎、酒精性肝病或其他病因)队列,根据年龄、性别和移植年份进行匹配,排除了无肝失代偿证据而列入名单的患者。根据 2020 年标准,CCM 定义为存在舒张功能障碍、左心室射血分数≤50%和/或整体纵向应变(GLS)绝对值<18%。研究超声心动图医师对临床数据不知情。移植后 CVD 包括新发冠状动脉疾病、充血性心力衰竭、心房和心室心律失常以及中风。该研究共纳入 141 例患者,其中 59 例为女性。LT 时的平均年龄为 57.8(±7.6)岁。共有 49 例(34.8%)患者患有 CCM。患有 CCM 的患者 LT 后 CVD 的风险增加(风险比,2.57;95%置信区间,1.2-5.5;P = 0.016)。移植前 CCM 各项参数(如 GLS、舒张早期二尖瓣血流速度与舒张早期二尖瓣环速度比、左心房容积指数)的变化与移植后 CVD 的风险增加相关。根据新标准诊断的 CCM 约影响三分之一的失代偿性 LT 候选者。CCM 预测 LT 后新发 CVD 的风险增加。需要进行研究以确定并随访以减轻这些风险。
