Given that as many as 47% of patients with non–ST-segment elevation myocardial infarction (non-STEMI) belong to the grade “0” Thrombolysis in Myocardial Infarction (TIMI) flow category (when angiography is performed, which, in most patients, is within 6 hours of arrival in hospital),1 it may be premature to state that
in the absence of ST-segment elevation, there is no therapy that can provide a large benefit such as immediate reperfusion with primary PCI or fibrinolytics.2(p1839)
