biostudies-literatureUnknown42(1)Wattanachayakul P<h4>Introduction</h4>The impact of protein-energy malnutrition (PEM) on patients hospitalized for conventional pacemaker implantation remains poorly understood.<h4>Methods</h4>We utilized the 2020 U.S. National Inpatient Sample (NIS) database to evaluate the impact of PEM on the in-hospital outcomes of patients who underwent conventional pacemaker implantation. Patients aged 18 and older were identified by ICD-10 CM and PCS codes. Multivariable survey logistic and linear regression analyses were employed to examine in-hospital outcomes, including in-patient mortality, system-based outcomes, and post-procedural complications.<h4>Results</h4>A total of 108 020 patients were identified with 4315 (3.99%) diagnosed with PEM. The mean age of the cohort was 76 years, and 47.5% were female.
