Abstract
Cirrhotic cardiomyopathy (CMP) is associated with altered cardiac electrophysiological (EP) properties, which leads to the risk of ventricular arrhythmias (VAs). We aimed to evaluate the EP properties, autonomic, and structural remodeling in a rabbit model with early liver cirrhosis (LC). Twelve rabbits were assigned to the sham and LC groups. The early-stage LC was induced by the ligation of the common bile duct. All rabbits received an EP study, VA inducibility test, myocardial, and liver histology staining. Western blot analyses of protein expression and tyrosine hydroxylase stain for sympathetic nerves were performed. The effective refractory period the LC group was significantly longer than the sham group [i.e., left ventricle (LV) 205.56 ± 40.30 vs. 131.36 ± 7.94 ms; right ventricle (RV) 206.78 ± 33.07 vs. 136.79 ± 15.15 ms; left atrium (LA) 140.56 ± 28.75 vs. 67.71 ± 14.29 ms; and right atrium (RA) 133.78 ± 40.58 vs. 65.43 ± 19.49 ms, all p < 0.01], respectively. The VA inducibility was elevated in the LC group when compared with the sham group (i.e., 21.53 ± 7.71 vs. 7.76 ± 2.44%, p = 0.013). Sympathetic innervation (102/μm2/mm2) was increased in all cardiac chambers of the LC group compared with the sham group (i.e., LV 9.11 ± 4.86 vs. 0.17 ± 0.15, p < 0.01; RV 4.36 ± 4.95 vs. 0.18 ± 0.12, p = 0.026; LA 6.79 ± 1.02 vs. 0.44 ± 0.20, p = 0.018; and RA 15.18 ± 5.12 vs. 0.10 ± 0.07, p = 0.014), respectively. Early LC is presented with an increased ventricular vulnerability, structural heterogeneity, and sympathetic innervation. Close monitoring for fatal arrhythmias is warranted in patients with early stages of LC.

Abstract
Hemodynamic instability (HDI) during liver transplantation (LT) can be difficult to manage and increases postoperative morbidity and mortality. In addition to surgical causes of HDI, patient- and graft-related factors are also important. Nitric oxide-mediated vasodilatation is a common denominator associated with end-stage liver disease related to HDI. Despite intense investigation, optimal management strategies remain elusive. In this consensus article, experts from the International Liver Transplantation Society, the Liver Intensive Care Group of Europe, and the Society for the Advancement of Transplant Anesthesia performed a rigorous review of the most current literature regarding the epidemiology, causes, and management of HDI during LT. Special attention has been paid to unique LT-associated conditions including the causes and management of vasoplegic syndrome, cardiomyopathies, LT-related arrhythmias, right and left ventricular dysfunction, and the specifics of medical and fluid management in end-stage liver disease as well as problems specifically related to portal circulation. When possible, management recommendations are made.

Abstract
Cirrhotic cardiomyopathy (CCM), cardiac dysfunction in end-stage liver disease in the absence of prior heart disease, is an important clinical entity that contributes significantly to morbidity and mortality. The original definition for CCM, established in 2005 at the World Congress of Gastroenterology (WCG), was based upon known echocardiographic parameters to identify subclinical cardiac dysfunction in the absence of overt structural abnormalities. Subsequent advances in cardiovascular imaging and in particular myocardial deformation imaging have rendered the WCG criteria outdated. A number of investigations have explored other factors relevant to CCM, including serum markers, electrocardiography, and magnetic resonance imaging. CCM characteristics include a hyperdynamic circulatory state, impaired contractility, altered diastolic relaxation, and electrophysiological abnormalities, particularly QT interval prolongation. It is now known that cardiac dysfunction worsens with the progression of cirrhosis. Treatment for CCM has traditionally been limited to supportive efforts, but new pharmacological studies appear promising. Left ventricular diastolic dysfunction in CCM can be improved by targeted heart rate reduction. Ivabradine combined with carvedilol improves left ventricular diastolic dysfunction through targeted heart rate reduction, and this regimen can improve survival in patients with cirrhosis. Orthotopic liver transplantation also appears to improve CCM. Here, we canvass diagnostic challenges associated with CCM, introduce cardiac physiology principles and the application of echocardiographic techniques, and discuss the evidence behind therapeutic interventions in CCM.

Abstract
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.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. We prospectively evaluated endothelial function by assessing flow-mediated dilatation (FMD) of the brachial artery in patients with biopsy-proven NAFLD. This prospective study included 139 patients (50 healthy controls, 47 patients with steatosis and 42 patients with steatohepatitis), all of whom were nondiabetic. Patients with long-standing or uncontrolled hypertension, smokers, and morbidly obese patients were excluded. The medians (ranges) for vascular FMD in the steatohepatitis, steatosis, and control groups were 6% (0–37.5%), 10.8% (0–40%) and 13.6% (0–50%), respectively. The control group had a higher average FMD than the NAFLD group (15.13% vs 10.46%), and statistical significance was reached when the control and steatohepatitis groups were compared (13.6% vs 6%, p = 0.027). Average alanine aminotransferase was significantly higher in the steatohepatitis group than in the steatosis and control groups (54 (U/L) vs 31 (U/L), p = 0.008). Cholesterol levels were similar between all groups. In the multivariate analysis, FMD (OR = 0.85, p = 0.035) and high triglycerides (OR = 76.4, p = 0.009) were significant predictors of steatohepatitis. In the absence of major cardiac risk factors, we demonstrated better endothelial function in healthy controls, evidenced by a higher FMD of the brachial artery than that of patients with steatohepatitis.

Abstract
Introduction: Despite the normal systolic function at rest, cirrhotic patients often suffer from volume overload and symptoms of heart failure as they face stressful situations. This study investigated the myocardial reserve in cirrhotic patients at resting condition and peak stress by dobutamine speckle tracking echocardiography (STE) and tissue Doppler imaging (TDI).
Methods: Twenty cirrhotic patients and 10 normal individuals aged 30-50 were selected randomly. For all of the participants, complete echocardiographic study of 2D, STE and TDI was done at rest and peak stress status with dobutamine. The following parameters were assessed: ejection fraction (EF), global longitudinal LV strain (GLS), strain rate in the septal basal segment and lateral wall and E’ in the septal basal segment by color-coded method.
Results: At baseline, EF was higher than 55% in both groups. GLS was higher (-22.6±2.4%) in the case group than the control group (-19.2±1.9%) at resting condition. After stress, it showed a greater increase (-22.5±1.7%) in the controls compared to cirrhotic patients (-22.6±3.3%; mean difference = 2.6 ± 2.03, P = 0.02). In cirrhotic patients, the average strain rate in the basal septal segment decreased after stress (-1.2 ± 0.3/s to-1.1 ± 0.3/s), but it increased in the control group (-1.1 ± 0.2/s to -1.8 ± 0.2/s).
Conclusion: Despite the presence of normal resting systolic function in cirrhotic patients, there was insufficient increase or even a decrease in myocardial function with stress; this may indicate the absence of sufficient myocardial reserve in cirrhotic patients. These findings would help to explain the reason for occurrence of heart failure or hemodynamic changes in cirrhotic patients.

Abstract
Cirrhotic cardiomyopathy historically has been confused as alcoholic cardiomyopathy. The key points for diagnosis of cirrhotic cardiomyopathy have been well explained, however this entity was neglected for a long time. Nowadays the diagnosis of this entity has become important because it is a factor that contributes significantly to morbidity-mortality in cirrhotic patients. Characteristics of cirrhotic cardiomyopathy are a hyperdynamic circulatory state, altered diastolic relaxation, impaired contractility, and electrophysiological abnormalities, particularity QT interval prolongation. The pathogenesis includes impaired function of beta-receptors, altered transmembrane currents and overproduction of cardiodepressant factors, such as nitric oxide, cytokines and endogenous cannabinoids. In addition to physical signs of hyperdynamic state and heart failure under stress conditions, the diagnosis can be done with dosage of serum markers, electrocardiography, echocardiography and magnetic resonance. The treatment is mainly supportive, but orthotopic liver transplantation appears to improve this condition although the prognosis of liver transplantation in patients with cirrhotic cardiomyopathy is uncertain.

Abstract
BACKGROUND & AIMS The current study aimed at assessing the potential role of cardiac abnormalities in the pathogenesis of circulatory and renal dysfunction in cirrhosis. METHODS One hundred and fifty-two patients (34 without ascites, 95 with ascites without renal failure and 21 with hepatorenal syndrome) were evaluated using Doppler echocardiography. In 102 patients, diastolic function was assessed by measuring parameters related to ventricular filling velocity, mitral annulus velocity and left atrial dimensions. Cardiopulmonary pressures were also measured by cardiac catheterization in 54 patients. In 50 additional patients, left ventricular myocardial strain was performed to estimate myocardial contractility and systolic function. RESULTS Grade 1 and 2 diastolic dysfunction was present in 41% and 16% of the patients, respectively. There was no patient with severe grade 3 diastolic dysfunction. Grade 2 diastolic dysfunction was associated with higher cardiopulmonary pressures but values were within the normal limits in all cases. Diastolic dysfunction directly correlated with liver failure but not with the degree of impairment in circulatory and renal function. The proportion of patients without or with grade 1 or 2 diastolic dysfunction was similar in patients with compensated cirrhosis, with ascites without renal failure or with hepatorenal syndrome despite marked differences in the degree of circulatory dysfunction, as indicated by plasma renin activity and noradrenaline concentration. The heart rate and systolic function were normal in all cases. There were no differences between patients without ascites, with ascites without renal failure or with HRS, despite marked differences in the activity of the renin-angiotensin system and sympathetic nervous system. These features indicate an impaired response of cardiac chronotropic and inotropic function to changes in systemic hemodynamics. CONCLUSIONS These data indicates that: (1) diastolic dysfunction is frequent in cirrhosis but in most cases it is of mild degree and does not increase the cardiopulmonary pressure to abnormal levels. This feature, which may be due to the central hypovolemia of cirrhosis, probably accounts for the lack of symptoms associated with this condition. (2) Diastolic dysfunction in cirrhosis is unrelated to circulatory dysfunction, ascites and HRS. (3) In cirrhosis, there is a lack of response of the left ventricular systolic and chronotropic function to peripheral arterial vasodilation and activation of the sympathetic nervous system and this feature is an important contributory factor to the progression of circulatory dysfunction and the pathogenesis of ascites and HRS.

Abstract
Cirrhosis is a frequent and severe condition, which is the late stage of numerous chronic liver diseases. It is associated with major hemodynamic alterations characteristic of hyperdynamic circulation and with a series of structural, functional, electrophysiological and biological heart abnormalities termed cirrhotic cardiomyopathy. The pathogenesis of this syndrome is multifactorial. It is usually clinically latent or mild, likely because the peripheral vasodilatation significantly reduces the left ventricle afterload. However, sudden changes of hemodynamic state (vascular filling, surgical or transjugular intrahepatic porto-systemic shunts, peritoneo-venous shunts and orthotopic liver transplantation) or myocardial contractility (introduction of beta-blocker therapy) can unmask its presence, and sometimes convert latent to overt heart failure. Cirrhotic cardiomyopathy may also contribute to the pathogenesis of hepatorenal syndrome. This entity has been described recently, and its diagnostic criteria are still under debate. To date, current management recommendations are empirical, nonspecific measures. Recognition of cirrhotic cardiomyopathy depends on a high level of awareness for the presence of this syndrome, particularly in patients with advanced cirrhosis who undergo significant surgical, pharmacological or physiological stresses.

Abstract
BACKGROUND Heart rhythm turbulence (HRT) is a novel tool for evaluation of cardiovascular mortality. Liver cirrhosis is associated with hemodynamic and myocardial disturbances termed cirrhotic cardiomyopathy. In the stable stage of liver cirrhosis, systolic and myocardial dysfunction is correlated with brain natriuretic peptide (BNP). The aim was to evaluate HRT and its correlation with NT-proBNP, echocardiographic and biochemical parameters in patients with decompensation of liver cirrhosis. MATERIAL/METHODS The study included 18 patients with decompensated liver cirrhosis and 18 healthy volunteers. Participants underwent echocardiography and 24-hour ECG monitoring. Serum NT-proBNP and other biochemical parameters were measured. Turbulence onset (TO) and turbulence slope (TS) were used to indicate HRT. RESULTS Mean HR (87/min vs. 75/min), TO (-0.385% vs. -0.92%), NT-proBNP (304.85 pg/ml vs. 83.2 pg/ml), LAd (42.5 mm vs. 34.5 mm), RVdd (29.5 mm vs. 25 mm), SPAP (36.5 mmHg vs. 22.5 mmHg) were significantly (p<0.05) higher in patients with liver cirrhosis. Patients with normal TO and TS had better stage in Child-Pugh classification (P=0.04) than patients with abnormal values. Significant negative correlation was found between creatinine and TO, and between mean HR and TS, and significant positive correlation was found between LAd and TS. LV diastolic dysfunction was noted in a majority of cirrhotic patients (n=16). CONCLUSIONS Patients with decompensated cirrhosis had elevated levels of NT-proBNP and LV diastolic dysfunction. TO values in cirrhotic patients differed significantly from the control group. These findings can indicate risk of symptomatic heart failure development and may be a marker of cirrhotic cardiomyopathy. HRT parameters seem not to be appropriate death predicators.

Abstract
End-stage renal disease, cirrhosis, obesity, tachycardia, and extreme stress have all been shown to result in impaired left ventricular function. It is becoming clear, however, that the cardiomyopathies associated with these states are reversible after resolution of the underlying process. In this article, we present the current data demonstrating that renal transplantation, liver transplantation, and bariatric surgery can lead to reversal of uremic, cirrhotic, and obesity cardiomyopathies, respectively. We also discuss the reversibility of tachycardia-induced cardiomyopathy after radiofrequency ablation or pharmacologic therapy for rate or rhythm control and the reversibility of stress-induced cardiomyopathy with supportive care.

Abstract
The effect of telbivudine on cardiac repolarization was evaluated in healthy participants at clinical and supratherapeutic doses. Sixty-two participants were enrolled, stratified by sex, and randomized according to a crossover design among 4 treatment sequences: placebo, a single moxifloxacin 400-mg dose as positive calibrator, and telbivudine 600 and 1800 mg/d for 7 days. Intensive time-matched electrocardiogram measurements and pharmacokinetic sampling were performed at baseline and on day 7 over 24 hours. For telbivudine and moxifloxacin, time-matched, placebo-adjusted change from baseline in QT was calculated and corrected using Fridericia's formula (QTcF). While moxifloxacin produced the expected significant changes in QTcF, none of the changes in QTcF for either doses of telbivudine exceeded 5 ms, and none of the associated upper 1-sided 95% confidence intervals (CI) exceeded the limit of 10 ms. There was no increase in QTcF with increasing plasma telbivudine. The supratherapeutic dose of telbivudine was well tolerated with a safety profile similar to the clinical dose despite a 3-fold increase in plasma exposure. This study therefore met the criteria for a negative thorough QT study. Telbivudine had no adverse effect on cardiac repolarization in healthy participants, even at supratherapeutic exposure, suggesting a broad safety margin.

Abstract
Left-sided heart failure (LHF) after liver transplantation (LT) is rare and poorly understood. We performed a case-control study. We reviewed the data of all patients with LHF after LT at our center from November 2000 to July 2007. Each case was matched to 1 LT control without LHF for age, sex, date of transplantation, and liver disease. Twenty of 599 patients developed LHF (3.3%). Pretransplant cardiovascular characteristics and risk factors were similar in cases and controls, except for the prevalence of left ventricular enlargement, which was greater in controls. At the time of diagnosis, the median left ventricular ejection fraction was 25% in cases, and increased afterload was documented by markedly elevated vascular resistances. The prevalence of infection at the time of LHF in cases was higher (55%) than in controls (10%, P = 0.02). The reported causes of LHF were infection [bacterial (n = 1) or viral (n = 7)], intraoperative cardiac arrest (n = 2), and unknown (n = 10). In comparison with their controls, cases with immediate postoperative LHF (day 0) did not have a higher Model for End-Stage Liver Disease (MELD) score (15 versus 21.5) or infection prevalence rate (17% versus 34%), whereas those with later onset LHF had a significantly higher MELD score (25.5 versus 17, P = 0.01) and infection prevalence rate (71% versus 0%, P = 0.002). Mortality was 45% in cases versus 0% in controls (P = 0.004), and the 11 cases who survived recovered from LHF. In conclusion, LHF after LT carries a high mortality risk and may have different causes. Except for immediate postoperative cases, an infection and an elevated MELD score appear to be determinant.

Abstract
Variceal bleeding is the last step in a chain of events initiated by an increase in portal pressure, followed by the development and progressive dilation of varices until these finally rupture and bleed. This sequence of events might be prevented - and reversed - by achieving a sufficient decrease in portal pressure. A different approach is the use of local endoscopic treatments at the varices. This article reviews the rationale for the management of patients with cirrhosis and portal hypertension, the current recommendations for the prevention and treatment of variceal bleeding, and outlines the unsolved issues and the perspectives for the future opened by new research developments.
