BACKGROUND: Cohort studies of STEMI patients have reported that over 30% receive no reperfusion. Barriers to greater use of reperfusion in STEMI patients require further elucidation. METHODS: We collected data on STEMI patients with no reperfusion as part of the SNAPSHOT ACS Registry, which recruited consecutive ACS patients in 478 hospitals throughout Australia and New Zealand during 14-27 May 2012. RESULTS: Of 4387 patients enrolled, 419 were diagnosed with STEMI. Primary PCI (PPCI) was performed in 160 (38.2%), fibrinolysis was used in 105 (25.1%), and 154 (36.7%) had no reperfusion. Patients with no reperfusion had a mean age of 70.3+/-15.0 years compared with 63.1+/-13.5 in the reperfusion group (p<0.0001). There were more females in the no reperfusion group (37.1% v 23.0% p=0.002) and they were significantly more likely to have prior PCI or CABG, heart failure, atrial fibrillation, chronic kidney disease and other vascular disease, and to be nursing home residents (all p<0.05). Patients without reperfusion had a significantly higher mortality in hospital (11.7% v 4.9%, p=0.011). In 370 patients who presented within 12hours, 28 had early angiography without PCI, which was considered an attempt at reperfusion. Therefore reperfusion was attempted in 293 of 370 eligible patients (79.2%). CONCLUSION: Of consecutive STEMI patients, 36.7% did not receive any reperfusion and they had a higher risk of death in hospital. In eligible patients, reperfusion was attempted in 79.2%. National strategies to encourage earlier medical contact and greater use of reperfusion in eligible patients may lead to better outcomes.
