Background and Objectives: Acute or severe limb ischemic events are limb- and life-threatening complications of peripheral artery disease (PAD). Although cirrhosis is increasingly recognized as a systemic disorder associated with endothelial dysfunction, inflammation, and altered hemostatic balance, its relationship with coding-defined limb ischemic events among individuals with PAD remains poorly defined. We investigated whether cirrhosis is independently associated with coding-defined acute or severe limb ischemic events among hospitalized adults with PAD. Materials and Methods: We performed a retrospective discharge-level analysis of the National Inpatient Sample from 2016 to 2018. Adult hospitalizations with PAD were identified using ICD-10-CM diagnosis codes and stratified according to the presence or absence of cirrhosis. The primary outcome was coding-defined acute or severe limb ischemic events. Multivariable logistic regression was used to evaluate the association between cirrhosis and acute or severe limb ischemic events after adjustment for demographic and cardiovascular comorbidities. Propensity-score matching was additionally performed to balance baseline characteristics between hospitalizations with and without cirrhosis. Results: Among 276,702 hospitalizations with PAD, 5942 had cirrhosis. Before matching, cirrhosis was independently associated with higher odds of acute or severe limb ischemic events after multivariable adjustment (odds ratio [OR] 1.47, 95% confidence interval [CI] 1.35-1.60; p < 0.001). After 1:1 propensity-score matching, 5883 matched pairs were analyzed. The association between cirrhosis and acute or severe limb ischemic events persisted in the matched cohort, with cirrhosis remaining significantly associated with increased odds of these events (OR 1.41, 95% CI 1.24-1.60; p < 0.001). Conclusions: In this large discharge-level analysis of hospitalizations with PAD, cirrhosis was independently associated with higher odds of coding-defined acute or severe limb ischemic events. These findings suggest that cirrhosis may represent an underrecognized vascular risk amplifier in PAD. Further prospective studies are needed to validate this association, clarify underlying mechanisms, and determine whether cirrhosis may improve PAD risk stratification.
