Abstract
BACKGROUND: <0.001), which was maintained after multivariate adjustment (1.20; 95% confidence interval, 1.08-1.33; P=0.001). In contrast, mortality was not significantly different between intermediate-volume and high-volume hospitals (4.8% versus 4.8%; adjusted odds ratio, 1.02; 95% confidence interval, 0.94-1.11; P=0.61). Door-to-balloon times were significantly shorter in high-volume hospitals compared with low-volume hospitals (median, 72 minutes; interquartile range, [53-91] versus 77 [57-100] minutes; P<0.0001).Conclusions-Higher annual hospital volume of primary PCI continues to be associated with lower mortality, with higher mortality in hospitals performing ≤36 primary PCIs/y.
