es following CV surgery. Methods: This retrospective cohort study used data from the National Inpatient Sample (2016-2020) to compare outcomes of PD and HD patients undergoing coronary artery bypass grafting and surgical valve procedures. Multivariable logistic regression, negative binomial regression, and linear regression models were used, adjusting for demographic factors, comorbidities, and hospital characteristics. The primary outcome was in-hospital mortality, and secondary outcomes included prolonged ventilation, length of stay, and hospital charges. Results: A total of 30,155 patients were included in the study, with 28,015 (92.9%) receiving HD and 2,140 (7.1%) receiving PD. Compared to HD, PD was associated with lower in-hospital mortality (OR 0.61, 95% CI 0.38-0.97), reduced prolonged ventilation (OR 0.51, 95% CI 0.32-0.81), shorter length of stay (IRR 0.85, 95% CI 0.80-0.91), and decreased hospital charges (mean difference -$87,172 USD, 95% CI -$113,523 to -$60,820) compared
