Changes in reperfusion strategy over time for ST segment elevation myocardial infarction in the Greater Paris Area: Results from the e-MUST Registry☆ , ☆☆

article i nfo Background: ESC guidelines recommend a shorter (90 min) delay for the use of primary percutaneous inter- vention (pPCI) in patients presenting within the first 2 h of pain onset. Using registry data on STEMI patients in the Greater Paris Area, we assessed changes between 2003 and 2008 in the rates of pPCI, pre-hospital fibrinolytic therapy (PHF) and time delays in patients presenting within 2 h of STEMI pain onset. Methods: The Greater Paris Area was divided in 3 regions: Paris, the small and large rings. Patients were divided in three groups according to their reperfusion strategy: a) PHF, b) timely pPCI (FMC to balloon infla- tion time b 90 min), and c) late pPCI (FMC to balloon inflation time N 90 min). Results: Among the 5592 patients included, 1695 (39%) had PHF, 1266 (29%) had timely pPCI, and 1415 (32%) had late pPCI. Over the 6 years, there was a sharp increase in timely pPCI in all regions, balanced by a decrease in PHF. The rate of late pPCI remained globally stable, with a decrease in Paris, stabilization in the small ring, and an increase in the large ring, where the density of catheterization laboratories was the lowest. By multivariate analy- sis, using on-time pPCI as a reference group, mortality was higher in the PHF and late pPCI groups. Conclusions: In areas with a low density of pPCI centers, efforts should be made to improve the timeliness of pPCI. Otherwise, PHF followed by an immediate transfer to a pPCI capable hospital may be considered. © 2013 Published by Elsevier Ireland Ltd.
