# A289 MAJOR ADVERSE CARDIAC EVENTS (MACE) IN PATIENTS WITH A HISTORY OF LIVER TRANSPLANTATION: A NATIONWIDE ANALYSIS USING THE NATIONAL INPATIENT SAMPLE

## TL;DR

This study finds that nearly a third of liver transplant patients have major adverse cardiac events, with higher rates of diabetes, hypertension, and obesity among those affected.

## Contribution

The study provides new insights into the prevalence and risk factors for MACE in liver transplant patients using nationwide data.

## Key findings

- 26.1% of post-liver transplant patients had prior MACE.
- MACE patients had higher odds of type 2 diabetes, hypertension, and dyslipidemia.
- Hospitalization with MACE was linked to increased in-hospital mortality.

## Abstract

Liver transplantation is the preferred treatment for end-stage liver disease. However, in around one-third of transplant recipients cardiovascular disease remains to be a significant contributor to morbidity and mortality.

Using data from the national inpatient sample (NIS), this study aimed to assess the prevalence and patient characteristics of MACE in those who underwent liver transplantation.

The study used a cross-sectional design to analyze NIS data, comparing MACE prevalence in hospitalized liver transplant patients. MACE included heart-related events. Patients with MACE and liver transplant history were identified using 2013 NIS data and ICD-9-CM codes. Baseline characteristics were compared, and association strength was assessed via logistic regression.

Out of 33,725 post-liver transplant patients, 26.1% (8,805) had prior MACE. Those with MACE had higher rates of comorbidities: type 2 diabetes (odds ratio (OR) 1.90, 95% CI 1.69-2.13, p ampersand:003C 0.001), hypertension (OR=2.07, 95% CI 1.83-2.34, pampersand:003C 0.001), dyslipidemia (OR=2.27, 95% CI 1.97-2.60, pampersand:003C 0.001), and morbid obesity (OR=1.69, 95% CI 1.39-2.04, pampersand:003C 0.001). Smoking wasn't significantly linked (p = 0.738). Hospitalization with MACE increased in-hospital mortality (3.25%, p ampersand:003C 0.001).

These findings highlight the importance of proactive cardiovascular risk factor management to minimize the morbidity and mortality of MACE in this patient population.
