In this study 300 consecutive patients with symptoms, clinical signs and ECG changes (≥4mm cumulated or ≥ 2mm ST-segment depression (horizontal or descending) in two associated leads) suggesting significant NSTEMI are randomized for one of two strategies, either (A) usual early invasive treatment (coronary angiography and possibly PCI after 3 days) or (B) direct referral (rerouting) to primary PCI at an invasive heart centre (Skejby).
