Early hospital discharge (<72 hours) after STEMI and primary PCI was associated with a 1.5% rate of major adverse cardiovascular events compared to 1.2% for standard discharge (p=0.616).

Does early hospital discharge (<72 hours) maintain safety outcomes compared to standard or late discharge in patients presenting with STEMI treated with primary PCI?
Early hospital discharge (<72 hours) appears safe for uncomplicated STEMI patients post-PCI, particularly those with non-LAD culprit lesions, without increasing 30-day readmission or MACE.
Absolute Event Rate: 1.5% vs 1.2%
p-value: p=0.616
BACKGROUND In regional settings, early hospital discharge after primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) could improve efficiency of healthcare systems. AIM This study aimed to assess the characteristics of patients after STEMI and PCI based on hospital length of stay and compare the differences in outcomes of patients according to their length of hospital stay. METHOD We performed a retrospective analysis of consecutive patients presenting with STEMI to our 24/7 PCI centre in regional Victoria, Australia between January 2022 and December 2022. Baseline patient characteristics, procedural data, and outcome data including 30-day hospital readmission, major adverse cardiovascular events, and mortality rates were collected. Patient data were compared between three groups: early discharge (5 days). RESULTS The early hospital discharge group had higher rates of a right coronary artery or left circumflex culprit vessel, with lower incidences of left ventricular systolic dysfunction. The major adverse cardiovascular event rate in the early discharge group was 1.5% compared with the standard and late discharge groups with 1.2% and 4.2%, respectively (p=0.616). The rates of hospital readmission of any type were similar between early discharge group and standard discharge group (13.2% and 14.8%, respectively; p=0.411). CONCLUSIONS In patients treated successfully with PCI after non-left anterior descending artery STEMI with an uncomplicated postprocedural course, early discharge may be safely achieved.
Thaw et al. (2026) conducted a cohort in ST-segment elevation myocardial infarction (STEMI). Early discharge (<72 hours) vs. Standard discharge (3-5 days) and late discharge (>5 days) was evaluated on Major adverse cardiovascular events (p=0.616). Early hospital discharge (<72 hours) after STEMI and primary PCI was associated with a 1.5% rate of major adverse cardiovascular events compared to 1.2% for standard discharge (p=0.616).
