Diastolic dysfunction diagnosed by tissue Doppler imaging in cirrhotic patients: Prevalence and its possible relationship with clinical outcome

Association of echocardiography-related parameters with the prognosis of decompensated cirrhosis: a retrospective cohort study

BACKGROUND

Cardiac morphology and function, which are conventionally evaluated by echocardiography, are often abnormal in decompensated cirrhosis. We aimed to evaluate the association of echocardiography-related parameters with prognosis in cirrhosis.

METHODS

This retrospective study included 104 decompensated cirrhotic patients, in whom cardiac structure and function were measured by echocardiography, including mitral inflow early diastolic velocity/mitral inflow late diastolic velocity (E/A), left atrium diameter, left ventricular end-diastolic dimension, interventricular septal thickness, left ventricular posterior wall thickness, right atrial transverse diameter, right atrial longitudinal diameter, right ventricular dimension (RVD), stroke volume, cardiac output, left ventricular ejection fraction, and fractional shortening. Cox regression and competing risk analyses and Kaplan-Meier and Nelson-Aalen cumulative risk curves were used to evaluate their associations with further decompensation and death in cirrhotic patients, if appropriate.

RESULTS

Lower RVD was a predictor of further decompensation in Cox regression (adjusted by Child-Pugh score: p = 0.138; adjusted by MELD score: p = 0.034) and competing risk analyses (p = 0.003), and RVD ≤17 mm was significantly associated with higher cumulative incidence of further decompensation in Kaplan-Meier (p = 0.002) and Nelson-Aalen cumulative risk curves (p = 0.002). E/A ≤ 0.8 was a significant predictor of death in Cox regression (adjusted by Child-Pugh score: p = 0.041; adjusted by MELD score: p = 0.045) and competing risk analyses (p = 0.024), and E/A ≤ 0.8 was significantly associated with higher cumulative incidence of death in Kaplan-Meier (p = 0.023) and Nelson-Aalen cumulative risk curves (p = 0.024). Other echocardiography-related parameters were not significantly associated with further decompensation or death.

CONCLUSION

RVD and E/A may be considered for the prognostic assessment of decompensated cirrhosis.

Use of Transesophageal Echocardiography During Orthotopic Liver Transplantation: Simplifying the Procedure

The intraoperative management of patients undergoing orthotopic liver transplantation (OLT) is influenced by the cardiovascular manifestations typically found in the context of end-stage liver disease, by the presence of concomitant cardiovascular disease, and by the significant hemodynamic changes that occur during surgery. Hypotension and intraoperative blood pressure fluctuations during OLT are associated with liver graft dysfunction, acute kidney failure, and increased risk of 30-d mortality. Patients also frequently present hemodynamic instability due to various causes, including cardiac arrest. Recent evidence has shown transesophageal echocardiography (TEE) to be a useful minimally invasive monitoring tool in patients undergoing OLT that gives valuable real-time information on biventricular function and volume status and can help to detect OLT-specific complications or situations. TEE also facilitates rapid diagnosis of life-threatening conditions in each stage of OLT, which is difficult to identify with other types of monitoring commonly used. Although there is no consensus on the best approach to intraoperative monitoring in these patients, intraoperative TEE is safe and useful and should be recommended during OLT, according to experts, for assessing hemodynamic changes, identifying possible complications, and guiding treatment with fluids and inotropes to achieve optimal patient care.

The predictive value of revised diastolic dysfunction in outcomes of liver transplantation: A propensity score matching analysis

Background

Diastolic dysfunction (DD), one of the earliest signs of cirrhotic cardiomyopathy (CCM), is included in the revised 2019 CCM criteria. Nonetheless, relevant research regarding the effects of revised DD on post-liver transplantation (LT) outcomes remains limited.

Methods

This retrospective study enrolled patients who underwent LT for decompensated cirrhosis, from January 2018 to March 2021. Patients were divided into DD and non-DD groups. Clinical data were collected. Patients were followed up with, for at least 1 year post-LT; cardiovascular adverse events (AEs) and survival status were recorded. Risk factors were identified using 1:2 propensity score matching (PSM), after adjusting for confounding factors. The caliper value was set to 0.02.

Results

Of 231 patients, 153 were diagnosed with DD (male, 81.8%; mean age, 51.5 ± 9.5 years). Nineteen patients with DD died within 1 year, post-LT. After PSM, 97 and 60 patients were diagnosed with and without DD, respectively. Patients with DD had longer intensive care unit (ICU) stays, higher perioperative cardiovascular AEs, and higher mortality rates than those without DD. In a multivariate analysis, interventricular septum (IVS), left atrial volume index (LAVI), and potassium levels were independent prognostic factors of perioperative cardiovascular AEs, while a decreased early diastolic mitral annular tissue velocity (e'), increased neutrophil-to-lymphocyte ratio (NLR) and tumor markers were predictors of mortality within 1 year post-LT after PSM (P < 0.05).

Conclusion

Cardiac DD may contribute to perioperative cardiovascular AEs and mortality post-LT. Clinicians should be aware of decompensated cirrhosis in patients with DD.

A Prospective Study of Prevalence and Predictors of Cirrhotic Cardiomyopathy and Its Role in Development of Hepatorenal Syndrome

BACKGROUND AND AIMS

Cirrhotic cardiomyopathy (CCM) is a term used to collectively describe abnormal structural and functional changes in heart of patients with cirrhosis. The present study was undertaken to find the prevalence of CCM in patients with liver cirrhosis and its predictors. We also followed these patients to evaluate the role of CCM in the development of hepatorenal syndrome (HRS).

MATERIALS & METHODS

This was a prospective study carried out in department of Gastroenterology, Sir Ganga Ram hospital, New Delhi. A total of 104 patients with liver cirrhosis were included. Liver cirrhosis was diagnosed on basis of clinical, biochemical, and imaging features. CCM was defined based on echocardiography. Dobutamine stress echocardiography and hepatic venous pressure gradient (HVPG) were performed in patients who gave consent. HRS was defined as per standard criteria. Patients with CCM were followed for development of HRS.

RESULTS

Fifty (48%) patients were diagnosed with CCM. All patients had diastolic dysfunction, and none had systolic dysfunction. Median age of patients with CCM was significantly higher (59 [31-78 y] vs. 52 [24-70 y], P < 0.05). Severity of liver disease (Child Turcotte Pugh score and model for end-stage liver disease score) and portal pressures (HVPG) did not differ in patients with or without CCM. Patients with CCM did not have increased incidence of HRS at the end of 6-month follow-up study.

CONCLUSION

The presence of CCM was not related with the severity of liver dysfunction or portal pressures. Age was a significant determinant of CCM. Diastolic cardiac dysfunction does not influence the occurrence of HRS.

Diagnosis and Prevalence of Cirrhotic Cardiomyopathy: A Systematic Review and Meta-analysis

The proposed diagnostic criteria for cirrhotic cardiomyopathy (CCM), defines it as documented echocardiographic findings of systolic or diastolic dysfunction (using conventional 2D echocardiogram), with or without electrophysiological abnormalities or elevated biomarkers in cirrhotic patients. In comparison to 2D echocardiogram, tissue Doppler imaging (TDI) has better sensitivity and specificity, when evaluating for cardiac dysfunction. This meta-analysis of 12 selected cohort studies attempted to estimate the pooled prevalence of CCM using either conventional echocardiography or TDI. Using the 2005 criteria, the pooled prevalence of CCM is 61% (P = 0.106). When TDI is used, the prevalence of CCM is at 45% (P = 0.088). Analyzing data of 615 cirrhotic patients, this study estimates the mean population-specific echocardiographic values of cirrhotic patients, including left ventricle ejection fraction (63.52%), deceleration time (229.04 ms), isovolumetric relaxation time (87.71 ms) and E/A ratio (1.04). In comparison to TDI, using standard 2D echocardiography leads to overdiagnosis of CCM.

Cirrhotic Cardiomyopathy - A Veiled Threat

Cirrhotic cardiomyopathy (CCM) is defined as cardiac dysfunction in patients with liver cirrhosis without pre-existing cardiac disease. According to the definition established by the World Congress of Gasteroenterology in 2005, the diagnosis of CCM includes criteria reflecting systolic dysfunction, impaired diastolic relaxation, and electrophysiological disturbances. Because of minimal or even absent clinical symptoms and/or echocardiographic signs at rest according to the 2005 criteria, CCM diagnosis is often missed or delayed in most clinically-stable cirrhotic patients. However, cardiac dysfunction progresses in time and contributes to the pathogenesis of hepatorenal syndrome and increased morbidity and mortality after liver transplantation, surgery or other invasive procedures in cirrhotic patients. Therefore, a comprehensive cardiovascular assessment using newer techniques for echocardiographic evaluation of systolic and diastolic function, allowing the diagnosis of CCM in the early stage of subclinical cardiovascular dysfunction, should be included in the screening process of liver transplant candidates and patients with cirrhosis in general. The present review aims to summarize the most important pathophysiological aspects of CCM, the usefulness of contemporary cardiovascular imaging techniques and parameters in the diagnosis of CCM, the current therapeutic options, and the importance of early diagnosis of cardiovascular impairment in cirrhotic patients.

Association of Cirrhosis and Cardiomyopathy

Introduction

We investigated association of pro-BNP, troponin-I, electrocardiography (ECG) and echocardiography (ECHO) during diagnosis and identification of cirrhotic cardiomyopathy in cirrhotic patients.

Materials and methods

Patients were divided into three groups as; compensated cirrhotic patients (group 1, n= 30), decompensated cirrhotic (group 2, n = 30) and control group (group 3, n = 30). ECHO, and ECG were performed, and troponin-I and levels of pro-BNP were analyzed.

Results

Average age of group 1 was 46.36 ± 16 years (range 19-86), 60% were female; group 2 was 57.03 ± 13.54 years (range 22-89), 56% female; and group 3 was 49.13 ± 0.95 years (range 18-80), 56% female. A significant increase in QTc was detected in compensated cirrhotic patients compared to the control group (p <0.05). Pro-BNP levels were significantly higher (p <0.05) in the compensated cirrhotic group compared to the control group. The levels of pro-BNP were also significantly higher in the decompensated cirrhotic group compared compensated cirrhosis group and control group (p <0.001).

Conclusion

The increase of pro-BNP levels with severity of the disease in cirrhotic patients and the prolongation of QTc interval supports an association between these factors with cardiomyopathy.

Liver cirrhosis and left ventricle diastolic dysfunction: Systematic review

BACKGROUND

Liver cirrhosis is a chronic hepatic disease which is associated with cardiovascular abnormalities. Hyperdynamic circulation in liver cirrhosis causes functional and structural cardiac alterations. The prevalence of left ventricle diastolic dysfunction (LVDD) in cirrhotic patients ranges from 25.7% to as high as 81.4% as reported in different studies. In several studies the severity of diastolic dysfunction (DD) correlated with a degree of liver failure and the rate of dysfunction was higher in patients with decompensated cirrhosis compared with compensated. Future directions of comprehensive assessment of cardiac function in cirrhotic patients might provide a better prognosis for these patients.

AIM

To clarify the correlation between the severity of liver cirrhosis and left ventricle diastolic dysfunction in the existing literature.

METHODS

Through January and February of 2019 at Vilnius University we conducted a systematic review of the global existing literature on the prevalence of left ventricle diastolic dysfunction in patients with liver cirrhosis. We searched for articles in PubMed, Medline and Web of science databases. Articles were selected by using adequate inclusion and exclusion criteria. Our interest was the outcome of likely correlation between the severity of cirrhosis [evaluated by Child-Pugh classes, Model For End-Stage Liver Disease (MELD) scores] and left ventricle diastolic dysfunction [classified according to American Society of Echocardiography (ASE) guidelines (2009, 2016)], as well as relative risk of dysfunction in cirrhotic patients. Subgroup analyses were performed to evaluate the ratio and grades of left ventricle diastolic dysfunction with respect to cirrhosis severity.

RESULTS

A total of 1149 articles and abstracts met the initial search criteria. Sixteen articles which met the predefined eligibility criteria were included in the final analysis. Overall, 1067 patients (out of them 723 men) with liver cirrhosis were evaluated for left ventricle diastolic dysfunction. In our systemic analysis we have found that 51.2% of cirrhotic patients had left ventricle diastolic dysfunction diagnosed and the grade 1 was the most prevalent (59.2%, P < 0.001) among them, the grade 3 had been rarely diagnosed - only 5.1%. The data about the prevalence of diastolic dysfunction in cirrhotic patients depending on Child-Pugh Classes was available from 5 studies (365 patients overall) and only in 1 research diastolic dysfunction was found being associated with severity of liver cirrhosis (P < 0.005). We established that diastolic dysfunction was diagnosed in 44.6% of Child-Pugh A class patients, in 62% of Child B class and in 63.3% of Child C patients (P = 0.028). The proportion of patients with higher diastolic dysfunction grades increases in more severe cirrhosis presentation (P < 0.001). There was no difference between mean MELD scores in patients with and without diastolic dysfunction and in different diastolic dysfunction groups. In all studies diastolic dysfunction was more frequent in patients with ascites.

CONCLUSION

This systemic analysis suggests that left ventricle diastolic dysfunction is an attribute of liver cirrhosis which has not received sufficient attention from clinicians so far. Future suggestions of a comprehensive assessment of cardiac function in cirrhotic patients might provide a better prognosis for these patients and give hint for better understanding of the left ventricle diastolic dysfunction pathogenesis in liver cirrhosis.

Cardiac diastolic dysfunction predicts poor prognosis in patients with decompensated liver cirrhosis

Background/Aims

Left ventricular diastolic dysfunction (LVDD) is an early manifestation of cardiac dysfunction in patients with liver cirrhosis (LC). However, the effect of LVDD on survival has not been clarified, especially in decompensated LC.

Methods

We prospectively enrolled 70 patients with decompensated LC, including ascites or variceal bleeding, at Daejeon St. Mary’s Hospital from April 2013 to April 2015. The cardiac function of these patients was evaluated using 2D echocardiography with tissue Doppler imaging. The diagnosis of LVDD was based on the American Society of Echocardiography guidelines. The primary endpoint was overall survival.

Results

Forty-four patients (62.9%) had LVDD. During follow-up (22.3 months), 18 patients died (16 with LVDD and 2 without LVDD). The survival rate was significantly lower in patients with LVDD than in those without LVDD (31.1 months vs. 42.6 months, P=0.01). In a multivariate analysis, the Child-Pugh score and LVDD were independent predictors of survival. Moreover, patients with a ratio of early filling velocity to early diastolic mitral annular velocity (E/e’) ≥ 10 (LVDD grade 2) had lower survival than patients with E/e’ ratio < 10.

Conclusions

The presence of LVDD is associated with poor survival in patients with decompensated LC. Therefore, it may be important to monitor and closely follow LVDD patients.

Transesophageal ultrasonography during orthotopic liver transplantation: Show me more

The first perioperative transesophageal echocardiography (TEE) guidelines published 21 years ago were mainly addressed to cardiac anesthesiologists. TEE has since expanded its role outside this setting and currently represents an invaluable tool to assess chamber sizes, ventricular hypertrophy, and systolic, diastolic, and valvular function in patients undergoing orthotopic liver transplantation (OLT). Right-sided microemboli, right ventricular dysfunction, and patent foramen ovale (PFO) are the most common intra-operative findings described during OLT. However, left ventricular outflow tract obstruction and left ventricular ballooning syndrome are more difficult to recognize and less frequent. Transesophageal ultrasonography (TEU) during OLT is also underused. Its applications are as follows: (1) assistance in the difficult placement of pulmonary arterial catheters; (2) help with catheterization of great vessels for external veno-venous bypass placement; (3) intra-operative evaluation of surgical liver anastomosis patency, if feasible, through the liver window; and (4) intra-operative investigation of "acute hypoxemia" due to pulmonary and cardiac issues using trans-esophageal lung ultrasound (TELU). The aims of this review are as follows: (1) to summarize the uses of TEE and TEU throughout all phases of OLT, and (2) to describe other new feasible applications.

Cirrhotic cardiomyopathy: Basic and clinical research

Cirrhotic cardiomyopathy (CCM) is a common complication of liver cirrhosis. Recent research found that a blunted inotropic and chronotropic response to stress, systolic and diastolic dysfunctions and prolongation of the QT interval are major reasons for the development of cardiovascular events under stress conditions in CCM patients. Myocardial apoptosis, abnormalities of adrenergic transduction pathways, gaseous signal molecule imbalance and derangement of various ion channels are involved in the development of CCM. The combination of measurement of BNP, H₂S, electrocardiogram and echocardiography (resting and stress) is' helpful in the diagnosis of CCM. Liver transplantation is the only proven treatment with specific effect on CCM. Monitoring of cardiac function and timely treatment in case of severe trauma and infection are effective measures for preventing cardiovascular events. Only aldosterone antagonists have certain effects on CCM. The clinical efficacy of TCM therapy needs to be verified in future studies. New agents, targeting its pathogenic mechanisms, such as supplementing exogenous hydrogen sulfide, may play a role in patients who cannot undergo liver transplantation.
