Heart attack timing study reveals key insights for NSTEMI care
NCT ID NCT07204847
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 407 people with a type of heart attack called NSTEMI to see if getting a heart procedure (coronary angiography) within 24 hours leads to better outcomes. Researchers checked how well following this timing guideline predicted death, another heart attack, stroke, or heart failure at 6 months. The goal was to understand the best timing for this procedure.

Inclusion Criteria: * Presence of chest pain with or without ECG changes * Elevation of troponin level \> 90th percentile or a significant increase between two dosages * Significant or non-significant coronary lesion confirming the diagnosis of coronary artery disease on coronary angiography (coronary angiography mandatory before inclusion to confirm NSTEMI) Exclusion Criteria: * STEMI (ST-segment elevation myocardial infarction) or equivalent (defined as chest pain with ECG changes and troponin elevation \> 5 times the normal with an occluded artery (TIMI 0, 1, or 2) during initial coronary angiography) * Very high-risk NSTEMI (hemodynamic instability, cardiogenic shock, recurrent/refractory chest pain despite optimal medical treatment, life-threatening arrhythmia, mechanical complication, heart failure clearly related to NSTEMI, ST depression \> 1mm/6 leads with ST elevation in aVR and/or V1) for which urgent coronary angiography is mandatory * Unstable angina (acute coronary syndrome without troponin elevation) * Troponin elevation without chest pain or symptoms suggestive of NSTEMI * Recovered cardiac arrest * Contraindication to coronary revascularization or coronary angiography * Other diagnoses considered after coronary angiography (e.g., myocarditis, Takotsubo syndrome) * Age \< 18 years
