Comparative Outcomes of Peritoneal and Hemodialysis in ESRD Patients with STEMI: A National Inpatient Sample Analysis (2016-2020).

ABSTRACT

End-stage renal disease (ESRD) patients are at increased risk of mortality, particularly due to cardiovascular events such as acute myocardial infarction. Hemodialysis and peritoneal dialysis are the two main treatment modalities for ESRD patients. Using data from the National Inpatient Sample (NIS) database, we conducted a retrospective study involving 25,435 ESRD patients diagnosed with ST-elevation myocardial infarction (STEMI) between 2016 and 2020, categorized by their dialysis regimen. Our analysis revealed comparable mortality rates between peritoneal dialysis (PD) and hemodialysis (HD) patients, but lower hospitalization costs and fewer complications among PD recipients. Over five years, we observed a notable decrease in STEMI mortality despite increased STEMI cases among HD patients. Conversely, HD patients experienced increased hospital stays and associated costs over the study period than PD patients, who demonstrated stable trends. This study highlights the implications of dialysis modality selection in managing costs and reducing morbidity among STEMI patients with ESRD.
