The optimal timing of coronary angiography (CAG) in high-risk patients with acute coronary syndrome without persisting ST-segment elevation (NST-ACS) remains undetermined. The NON-ST-Elevation Myocardial Infarction trial aimed to compare outcomes in NSTE-ACS patients randomized to acute CAG (STEMI-like approach) with patients randomized to medical therapy and subacute CAG. We randomized 496 patients with suspected NST-ACS based on symptoms and significant regional ST depressions and/or elevated point-of-care troponin T (POC-cTnT) (≥50 ng/l) to either acute CAG (&lt;2 hours, n = 245) or subacute CAG (&lt;72 hours, n = 251). The primary end point was a composite of all-cause death, reinfarction, and readmission with congestive heart failure within 1 year from randomization. A final acute coronary syndrome (ACS) diagnosis was assigned to 429 (86.5%) patients. The median time from randomization to revascularization was 1.3 hours in the acute CAG group versus 51.1 hours in the subacute CAG group (p &lt;0.001). The composite end point occurred in 25 patients (10.2%) in the acute CAG group and 29 (11.6%) in the subacute CAG group, p = 0.62. The acute CAG group had a 1-year all-cause mortality of 5.7% compared with 5.6% in the subacute CAG group, p = 0.96. In conclusion, neither the composite end point of all-cause death, reinfarction, and readmission with congestive heart failure nor mortality differed between an acute and subacute CAG approach in NSTE-ACS patients. However, identification of NSTE-ACS patients in the prehospital phase and direct triage to an invasive center is feasible, safe and may facilitate early diagnosis and revascularization.</p
