Clinical Outcomes of Early Repatriation for Patients With ST-Segment Elevation Myocardial Infarction: A...

Area of Science:

• Cardiology
• Interventional Cardiology
• Health Services Research

Background:

• Hospital resource limitations often necessitate early repatriation of ST-elevation myocardial infarction (STEMI) patients post-primary percutaneous coronary intervention (PCI) to non-PCI centers.
• The safety and implications of this early transfer strategy remain incompletely understood.
• This study addresses the clinical safety of repatriating STEMI patients to non-PCI facilities after successful PCI.

Purpose of the Study:

• To evaluate the safety of early patient repatriation from PCI centers to non-PCI centers for STEMI patients.
• To compare the outcomes of STEMI patients repatriated early versus those remaining at the PCI center.

Main Methods:

• A cohort of STEMI patients undergoing primary PCI between 2010-2012 was identified.
• Patients with shock or early mortality were excluded; propensity score matching was used to compare repatriated and non-repatriated groups.
• One-year all-cause mortality and readmission for recurrent myocardial infarction (MI) were the primary outcomes assessed.

Main Results:

• 430 well-matched pairs of STEMI patients were analyzed.
• No significant difference in 1-year all-cause mortality was observed between repatriated and non-repatriated groups (6.7% vs. 5.6%).
• However, the 1-year readmission rate for MI was significantly higher in the repatriated group (12.1%) compared to the non-repatriated group (5.8%).

Conclusions:

• Early repatriation of STEMI patients after primary PCI to non-PCI centers is associated with a significantly increased risk of readmission for myocardial infarction.
• This finding raises concerns about the safety of early repatriation strategies.
• Further investigation is warranted to fully understand the implications and optimize care pathways for STEMI patients transferred from PCI centers.
