- written informed consent.
Exclusion Criteria:
- persistent angina,
- ST-segment elevation myocardial infarction (STEMI),
- hemodynamic instability including cardiogenic shock,
- oral anticoagulation therapy,
- contraindications for glycoprotein IIb/IIIa inhibitors,
- other disease with life expectancy <6 months,
- known coagulopathy,
- pregnancy,
- other suspected causes of troponin elevation as myocarditis, secondary to hypertensive crisis, or after cardiac decompensation,
- no ability to consent, and
- participation in another study.

Arm Description
An occluded lesion was defined as a lesion with 100% stenosis or TIMI-flow grade 0 or 1.
A non-occluded lesion was defined as a lesion without 100% stenosis or TIMI-flow grade 0 or 1.
Outcomes
Primary Outcome Measures
MACE
composite of death, reinfarction and readmission for unstable angina within 6 months after inclusion
Secondary Outcome Measures
CK and CK-MB
Venous blood samples were taken at admission (baseline), and every 6 h subsequently for a period of 48 h.

5. Study Description
Brief Summary
It is assumed that patients with non-ST-elevation myocardial infarctions (NSTEMI) showing an infero- or posterolateral occluded culprit artery (OCA) during diagnostic angiography frequently elude standard 12-lead electrocardiogram diagnosis. In addition, coronary collaterals may have beneficial effects in patients with OCA.
Detailed Description
We examined consecutive NSTEMI patients within 48 h of symptom onset. All patients underwent early invasive angiography plus optimal medical therapy. We compared baseline characteristics, procedural findings including analysis of TIMI-flow and collaterals using the Rentrop-classification, 30-day and 6-months major adverse cardiovascular events (MACE) in patients with and without totally OCA.
