Impact of liver cirrhosis on ST-elevation myocardial infarction related shock and interventional management, a nationwide analysis

BACKGROUND & nbsp;Critical care is rapidly evolving with significant innovations to decrease hospital stays and costs. To our knowledge, there is limited data on factors that affect the length of stay and hospital charges in cirrhotic patients who present with ST-elevation myocardial infarction-related cardiogenic shock (SRCS).& nbsp;AIM & nbsp;To identify the factors that increase inpatient mortality, length of stay, and total hospital charges in patients with liver cirrhosis (LC) compared to those without LC.& nbsp;METHODS & nbsp;This study includes all adults over 18 from the National Inpatient Sample 2017 database. The study consists of two groups of patients, including SRCS with LC and without LC. Inpatient mortality, length of stay, and total hospital charges are the primary outcomes between the two groups. We used STATA 16 to perform statistical analysis. The Pearson's chi-square test compares the categorical variables. Propensity-matched scoring with univariate and multivariate logistic regression generated the odds ratios for inpatient mortality, length of stay, and resource utilization.& nbsp;RESULTS & nbsp;This study includes a total of 35798453 weighted hospitalized patients from the 2017 National Inpatient Sample. The two groups are SRCS without LC (n = 758809) and SRCS with LC (n = 11920). The majority of patients were Caucasian in both groups (67% vs 72%). The mean number of patients insured with Medicare was lower in the LC group (60% vs 56%) compared to the other group, and those who had at least three or more comorbidities (53% vs 90%) were significantly higher in the LC group compared to the non-LC group. Inpatient mortality was also considerably higher in the LC group (28.7% vs 10.63%). Length of Stay (LOS) is longer in the LC group compared to the non-LC group (9 vs 5.6). Similarly, total hospital charges are higher in patients with LC ($147407.80 vs $113069.10, P & LE; 0.05). Inpatient mortality is lower in the early percutaneous coronary intervention (PCI) group (OR: 0.79 < 0.11), however, it is not statistically significant. Both early Impella (OR: 1.73 < 0.05) and early extracorporeal membrane oxygenation (ECMO) (OR: 3.10 P < 0.05) in the LC group were associated with increased mortality. Early PCI (-2.57 P < 0.05) and Impella (-3.25 P < 0.05) were also both associated with shorter LOS compared to those who did not. Early ECMO does not impact the LOS; however, it does increase total hospital charge (addition of $24717.85, P < 0.05).& nbsp;CONCLUSION & nbsp;LC is associated with a significantly increased inpatient mortality, length of stay, and total hospital charges in patients who develop SRCS. Rural and Non-teaching hospitals have significantly increased odds of extended hospital stays and higher adjusted total hospital charges. The Association of LC with worse outcomes outlines the essential need to monitor these patients closely and treat them early on with higher acuity care. Patients with early PCI had both shorter LOS and reduced inpatient mortality, while early Impella was associated with increased mortality and shorter LOS. Early ECMO is associated with increased mortality and higher total hospital charges. This finding should affect the decision to follow through with interventional management in this cohort of patients as it is associated with poor outcomes and immense resource utilization.
