    AimsThe HERA Registry investigates logistics, adherence to standards, time intervals, and mortality in a regional network for primary percutaneous coronary intervention (PPCI) in ST-elevation myocardial infarction (STEMI) in a mixed urban and rural area.Methods And ResultsWe included 826 consecutive patients (pts) within the HERA network with its dedicated PPCI strategy (female n = 243, mean age 64 years, range 25-98 years) with acute STEMI (May 2007 until January 2010). 680 pts (82 %) received PPCI and 45 (5.4 %) acute bypass surgery. Of 512 pts seen by an emergency physician (EP) as first medical contact (FMC) 87 % received on-scene 12-lead ECG. ECG transmission rate to the PPCI center was 29 %. Median FMC-to-balloon time (CBT) was 135 min and door-to-balloon time (DBT) 70 min. With EP FMC DBT was 38 min with direct transfer to cath lab (n = 70), 69 min via ICU (n = 240), and 132 min via ER (n = 91, p < 0.01). Out of 826 pts, 143(17.3 %) presented in cardiogenic shock. In-hospital mortality was 8.8 % (n = 73), 35.7 % for shock pts versus 3.2 % for non-shock pts (p < 0.01). For pts receiving PPCI, in-hospital mortality was 6.2 %, for shock pts (n = 107) 28.0 %, and for non-shock pts (n = 573) 2.1 % (p < 0.01).ConclusionPrehospital management, CBT and DBT compare favourably to data from studies and registries, but do not yet fulfill strict guideline requirements. Real world mortality in non-shock pts is very low. Direct transfer to cath lab reduces DBTs by 49 %. For this crucial improvement, transmission of a 12-lead ECG to the PPCI center is mandatory.
