Discharge Timing of Patients Presenting With ST-Segment Elevation Myocardial Infarction: A Regional Experience

Area of Science:

• Cardiology
• Interventional Cardiology
• Health Services Research

Background:

• Early hospital discharge following percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) may enhance healthcare system efficiency in regional settings.
• Optimizing patient flow and resource utilization is crucial for managing acute cardiac events.

Purpose of the Study:

• To characterize patients undergoing PCI for STEMI based on their hospital length of stay.
• To compare clinical outcomes, including readmission and major adverse cardiovascular events (MACE), among patients with early, standard, and late discharge.

Main Methods:

• A retrospective analysis of STEMI patients treated with PCI between January 2022 and December 2022 in regional Australia.
• Patients were categorized into early (<72 hours), standard (3-5 days), and late (>5 days) discharge groups.
• Collected data included baseline characteristics, procedural details, 30-day readmission rates, MACE, and mortality.

Main Results:

• The early discharge group (n=?) had a higher proportion of right coronary artery or left circumflex culprit lesions and less left ventricular systolic dysfunction.
• Major adverse cardiovascular event (MACE) rates were comparable across groups: 1.5% (early), 1.2% (standard), and 4.2% (late) (p=0.616).
• Hospital readmission rates were similar between early (13.2%) and standard (14.8%) discharge groups (p=0.411).

Conclusions:

• Successful PCI for non-left anterior descending artery STEMI with an uncomplicated postprocedural course allows for safe early hospital discharge.
• This strategy may be beneficial for improving healthcare efficiency in specific patient cohorts.
• Further research could explore predictive factors for safe early discharge in STEMI patients.
