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 inflation time < 90 min), and c) late pPCI (FMC to balloon inflation time > 90 min).
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 analysis, using on-time pPCI as a reference group, mortality was higher in the PHF and late pPCI groups.
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.
