Impact of Off-Hours Versus On-Hours Primary Percutaneous Coronary Intervention on Myocardial Damage and Clinical Outcomes in ST-Segment Elevation Myocardial Infarction

Reinstadler SJ, Stiermaier T, Eitel C et al. Keywords: off-hours; on-hours; PPCI; myocardial damage; STEMI

ABSTRACT


There is an ongoing debate on potential differences in outcome between ST-segment elevation myocardial infarction (STEMI) patients presenting outside of usual hospital working hours (“off-hours”) compared with patients presenting during classical working hours (“on-hours”) (1,2). The aim of this study was to evaluate potential differences in the amount of salvaged myocardium and the extent of myocardial damage by applying cardiac magnetic resonance (CMR) imaging in a large contemporary cohort of STEMI patients.
