The impact of liver cirrhosis on in-hospital outcomes among patients hospitalized for cardiogenic shock: A propensity score matched retrospective cohort study.

BACKGROUND: Cardiogenic shock poses a critical challenge characterized by diminished cardiac output and organ perfusion. Timely recognition and risk stratification are essential for effective intervention. Liver cirrhosis adds complexity due to its diverse systemic manifestations. The effect of liver cirrhosis on in-hospital outcomes in cardiogenic shock remains underexplored. METHODS: We conducted a retrospective cohort study using the National Inpatient Sample database from 2016 to 2020, matching cirrhotic patients with non-cirrhotic counterparts using propensity scores. The Cochran-Mantel-Haenszel method was used to assess the impact of cirrhosis on in-hospital mortality and complications. Simple linear regression models were used to assess differences in length of stay and cost of hospitalization. RESULTS: There were a total of 44,288 patients in the cohort, evenly distributed between the group with and without liver cirrhosis. Mean age of the cohort was 64 years (SD 12.5), 69.7 % were males, and 61.3 % were white. The overall in-hospital mortality rate in the cohort was 37.2 % with higher odds of in-hospital mortality in cirrhotic patients [OR = 1.3; 95 % CI (1.25, 1.35)]. Patients with cirrhosis exhibited increased risks of bowel ischemia, acute kidney injury, and sepsis compared to those without cirrhosis. Additionally, they had a heightened overall risk of major bleeding, particularly gastrointestinal bleeding, but a lower risk of intracranial hemorrhage and access site bleeding. Conversely, patients with cirrhosis had lower odds of deep vein thrombosis and pulmonary embolism, as well as arterial access site thrombosis and dissection, leading to reduced odds of peripheral angioplasty, thrombectomy, and amputation. Cirrhotic patients also had increased length of stay and cost of hospitalization. CONCLUSION: Liver cirrhosis exacerbates outcomes in cardiogenic shock, necessitating tailored management strategies. Further research is warranted to optimize patient care and understand the underlying mechanisms.

Predictors of in-hospital outcomes for diverticular bleeding patients: a retrospective analysis of National Inpatient Sample data (2016-2020).

Background: Diverticular bleeding is the leading cause of lower gastrointestinal bleeding, affecting 3-5% of patients with diverticulosis. Current management protocols include resuscitation, diagnosis via direct visualization, computed tomography imaging, endoscopic interventions, angioembolization, and surgery when needed. However, predictive factors for outcomes and optimal interventions remain ambiguous. Methods: This retrospective cohort study analyzed data from the National Inpatient Sample (NIS) database (2016-2020) to determine predictors of adverse in-hospital outcomes in diverticular bleeding patients without perforation or abscess. Demographic and clinical data were extracted, and multivariate regression models were applied. Analysis was conducted using R statistical software (version 4.1.3), with significance set at P<0.05. Results: A total of 28,269 patients hospitalized for diverticular bleeding were identified. Age >85 years, moderate to severe Charlson Comorbidity Index, hypovolemic shock, blood transfusion requirement, and requirement for colectomy were significantly associated with greater in-hospital mortality. Factors such as late colonoscopy timing and colon resection led to longer hospital stays, while arterial embolization was predicted by older age, Black race, hypovolemic shock, and blood transfusion. Predictors of colon resection included advanced age, presence of colon cancer, and hypovolemic shock. Conclusions: Our retrospective study identified significant predictors of in-hospital outcomes among patients with diverticular bleeding, informing risk stratification and management strategies. Further research is warranted to validate these findings and refine management algorithms for improved patient care. Integrating these insights into clinical practice may enhance outcomes and guide personalized interventions in diverticular bleeding management.

Trends of Acute Myocardial Infarction Mortality in People Over 65 Years Old in the United States From 1999-2020: Insight From the CDC-WONDER Database.

Background Over the past two decades, there have been numerous advances in acute myocardial infarction (AMI) care. We assessed the impact of these advances on the trend of AMI-related mortality. Methods This retrospective analysis of the Centers for Disease Control's Wide-ranging Online Data for Epidemiologic Research (CDC_WONDER) database focused on AMI-related mortality in individuals aged 65 and older in the United States from 1999 to 2020. Trends -n crude and age-adjusted mortality rates (AAMR) were assessed based on socio-demographic and regional variables using Joinpoint Regression software (Joinpoint Regression Program, Version 5.0.2 - May 2023; Statistical Methodology and Applications Branch, Surveillance Research Program, National Cancer Institute Bethesda, Maryland). Annual percentage change (APC) with 95% confidence intervals (CIs) for the AAMRs were calculated for the line segments linking a Joinpoint using a data-driven weighted Bayesian Information Criterion (BIC) model. Results There were 2,354,971 AMI-related deaths with an overall decline in the AAMR from 474.6 in 1999 to 153.2 in 2020 and an average annual percentage change (AAPC) of -5.3 (95% CI -5.4 to -5.2). Notable declines were observed across gender, race, age groups, and urbanization levels. However, the rate of AMI-related deaths at decedents' homes slowed down between 2008 and 2020 and climbed up between 2018 and 2020. In addition to this, nonmetropolitan areas were found to have a significantly lower decline in mortality when compared to large and medium/small metropolitan areas. Conclusion While there is an overall positive trend in reducing AMI-associated mortality, disparities persist, emphasizing the need for targeted interventions.

Association Between Chronic Liver Disease and Adverse In-Hospital Outcomes in Patients Undergoing CABG: A Propensity Score-Matched Analysis.

Despite a 30% decrease in the rate over the last decade, coronary artery bypass graft (CABG) surgery remains a common major surgical procedure with significant morbidity and mortality. Chronic liver disease (CLD) patients, with increased survival rates because of medical advancements, are now frequently being considered for CABG, bearing higher perioperative risks. This study investigates the association between CLD and in-hospital outcomes in CABG patients using retrospective data from the National Inpatient Sample database (2016 to 2020) including 7,945 CLD patients who underwent CABG that were propensity score-matched with an equivalent number of patients without CLD who underwent CABG. Clinical variables were extracted using corresponding International Classification of Diseases, Tenth Revision codes, and multivariable logistic and linear regression models were used to assess in-hospital mortality, complications, and length of stay. The overall mortality rate was 5.5% (8.6% in the CLD group with cirrhosis, 5.9% CLD group without cirrhosis, and 2.8% in the non-CLD group, p <0.001). CLD with cirrhosis was associated with higher odds of mortality (adjusted odds ratio = 4.21, 95% confidence interval 3.61 to 4.94) and length of stay (ß = 1.03, 95% confidence interval 1.01 to 1.05). CLD patients with cirrhosis demonstrated higher odds of perioperative cardiac complications (cardiac arrest, ventricular arrhythmias, tamponade, and shock), thromboembolic events, gastrointestinal bleeding, bowel ischemia, acute kidney injury, pneumonia, and sepsis. This study reveals a substantial impact of CLD on adverse outcomes in CABG patients, emphasizing the need for tailored preoperative assessments and postoperative care.
