Trial name or title	Timing of invasive strategy in acute coronary syndrome without ST segment elevation in groups of patients with different ischemic risk
Methods	Randomized controlled trial
Participants	178 participants with UA/NSTEMI
Interventions	Early invasive (coronary angiography‐SCAG and percutaneous intervention‐PCI in the first 24 hours after admission); selective invasive (attempt for medical stabilization and proceeding to SCAG only in case of angina recurrence and/or evidence of inducible myocardial ischaemia
Outcomes	Choice of an early invasive strategy in participants with acute coronary syndrome without ST elevation in the presence of high risk features is associated with a reduced incidence of MACE compared to a selective invasive strategy. In the subgroups of participants without high risk characteristics the advantages of early versus selective are not as clear
Starting date
Contact information	University Hospital St. Ekaterina, Sofia, Bulgaria
Notes	Full study not yet analysed/published. We extracted details from a conference abstract

UA = unstable angina; NSTEMI = non ST segment myocardial infarction; SCAG = Selective coronary angiography; PCI = Percutaneous coronary intervention; MACE = Major adverse cardiac events
