Objectives Comparing clinical outcomes after cardiopulmonary bypass with hemodsorption (HA) versus cardiopulmonary bypass without HA in patients undergoing cardiac surgery in terms of mortality and major complications. Methods PubMed, Scopus, and Web of Science databases were searched for relevant randomized control trials (RCTs) that compared postoperative clinical outcomes between patients receiving intraoperative HA with cardiopulmonary bypass versus patients receiving cardiopulmonary bypass without intraoperative HA in cardiac surgery. Results Sixteen RCTs with 851 patients (433 in the HA group and 418 in the control group), were included in our meta-analysis. Our meta-analysis found no significant differences between the intraoperative HA group and the control group in patients undergoing cardiac surgery in terms of 30-days/in-hospital mortality, new-onset atrial fibrillation, stroke or cerebrovascular events, postoperative delirium, renal failure/acute kidney injury, need for renal replacement, postoperative liver dysfunction, thrombocytopenia, bleeding, volume of blood loss, pneumonia, sepsis, respiratory insufficiency, duration of postoperative ventilation, distributive/septic shock, pericardial tamponade, need for extracorporeal membrane oxygenation (ECMO) support, sequential organ failure assessment (SOFA) score at ICU admission, plasma-free hemoglobin levels, and fibrinogen levels. However, the pooled analysis showed a significant association between HA and decreased albumin at ICU admission (MD = − 0.28, 95% CI [0.55 to 0.01], p -value = 0.04), decreased length of ICU stay (MD = −0.66, 95% CI [−1.24 to 0.08], p -value = 0.03), and decreased length of hospital stay (MD = −0.99, 95% CI [−1.88 to −0.10], p -value = 0.03). Conclusion Our findings suggest that there is not enough evidence to endorse the role of routine intraoperative HA during cardiopulmonary bypass in improving clinical outcomes after cardiac surgery. Factors such as patient risk profile, procedure complexity, and cost implications should be taken into account when considering this adjunct therapy.

Background Patients with cardiohepatic syndrome are at higher risk of adverse outcomes in the cardiac intensive care unit. We hypothesized that cardiohepatic syndrome phenotypes would exhibit differences in their clinical and transthoracic echocardiogram hemodynamic profiles, portending a higher risk of mortality. Methods We included unique CICU patients with an admission diagnosis of heart failure from 2007 to 2018 with available data for 1 or more admission liver function tests. Echocardiographic variables were extracted from patients who had a transthoracic echocardiogram within 1 day of admission. We assigned patients to 1 of 4 mutually exclusive cardiohepatic syndrome phenotype groups: normal, hepatocellular, cholestasis, and combined. Results We included 3992 CICU patients; 2483 had an available transthoracic echocardiogram. Patients with cholestasis had more right ventricular systolic dysfunction and congestion, whereas those with hepatocellular injury had more left ventricular systolic dysfunction and poor forward flow; hemodynamics and biventricular function were worst in the combined group. In‐hospital mortality occurred in 14.6% and was higher for patients with cholestasis or hepatocellular injury, especially those with greater extent/severity and worse biventricular function or poor hemodynamics. After adjustment, only the group with hepatocellular injury (adjusted odds ratio [OR], 1.35 [95% CI, 1.04–1.75], P =0.03) and the combined group (adjusted OR, 1.75 [95% CI, 1.30–2.34], P <0.001) remained at higher risk. One‐year mortality was highest in the combined group (adjusted hazard ratio [HR], 1.29 [95% CI, 1.10–1.51], P =0.002). Conclusions Cardiohepatic syndrome phenotypes are associated with distinct echocardiographic profiles. Patients with the combined cardiohepatic syndrome phenotype were at highest risk of mortality, particularly if this was combined with poor cardiac function.

Abstract Introduction Non-cardiovascular end-organ dysfunction is an important determinant of outcomes in cardiac intensive care unit (CICU) patients. We examined the association between in-hospital mortality with the severity and extent of admission liver function test (LFT) abnormalities in a heterogeneous CICU population. Purpose We hypothesized that a greater severity or extent of LFT abnormalities would be associated with higher in-hospital mortality. Methods We included consecutive unique adult CICU patients with available data for one or more of the admission LFT values of interest. Admission laboratory values were defined as those closest to CICU admission. We used the NIH Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 to categorize the severity of each LFT abnormality from Grade 0 (normal) to Grade 4 (life-threatening). We defined the extent of LFT abnormality as the number of individual LFTs meeting criteria for CTCAE Grade 1 or greater. The primary outcome of interest was all-cause in-hospital mortality. Odds ratio (OR) and 95% confidence interval (CI) values for in-hospital mortality were estimated using logistic regression, before and after multivariable adjustment. Results Of 12,428 unique CICU patients, 5,144 were excluded due to a lack of available data for any admission LFT values. The remaining 7,284 patients comprised the final study population. Among patients with available data for each individual LFT, abnormal values were present in: AST, 2,743/5,733 (47.8%); ALT 1,576/5,512 (28.6%); ALK 611/3,684 (16.6%); and TB 898/5,155 (17.4%). A total of 864 (11.9%) patients died during hospitalization. In-hospital mortality was higher for patients with one or more LFTs meeting criteria for CTCAE Grade 1 or greater (17.9% vs. 6.4%, adjusted OR 1.54 [1.27-1.86], p &lt;0.001). A stepwise increase in in-hospital mortality was observed with increasing CTCAE grade, both overall (adjusted OR 1.25 per each higher CTCAE grade [1.16-1.34], p &lt;0.001); (Figure 1A), and for each individual LFT (Figure 1B). Conclusion Cardiohepatic syndrome is an important predictor of prognosis in CICU patients, as the extent and severity of LFT abnormalities are strongly associated with in-hospital mortality. This is the first large-scale study to examine the association between the magnitude of hepatic biomarker derangement with in-hospital mortality in unselected CICU patients. Patients with markedly elevated LFT values exhibited the highest risk of in-hospital mortality. This analysis advocates for the inclusion of commonly obtained LFTs in future risk-prediction tools for enhanced prognostication.
