    AbstractDoor-to-balloon (DTB) time is an important metric in primary percutaneous coronary intervention (PCI) for acute ST-segment elevation myocardial infarction to optimize clinical outcomes. The aim of this study was to compare the impact of immediate PCI on culprit lesions in patients with ST-segment elevation myocardial infarctions versus diagnostic angiography followed by PCI on DTB times and procedural data at a high-volume tertiary care radial center. All patients who underwent primary PCI <12 hours after symptom onset were studied. Procedural data and all-cause mortality were assessed in all patients. The primary outcome was DTB time. From January 2006 to June 2011, 1,900 patients were included and divided into 2 groups: 562 patients (30%) underwent primary PCI followed by contralateral diagnostic angiography, and 1,338 patients (70%) underwent diagnostic angiography before primary PCI. No significant differences were observed in baseline characteristics. Left anterior descending coronary artery-related ST-segment elevation myocardial infarctions were more often found in patients who underwent PCI first (54% vs 34%, p <0.0001). Overall, there was a reduction of 8 minutes in DTB time between patients who underwent PCI first and those who underwent angiography first (32 minutes [interquartile range 24 to 52] vs 40 minutes [interquartile range 30 to 69], respectively, p <0.0001). After adjustment, immediate PCI remained an independent predictor of DTB time ≤90 minutes (odds ratio 2.42, 95% confidence interval 1.70 to 3.52, p <0.0001). There were no differences in early and late clinical outcomes. In conclusion, a strategy of transradial direct PCI of the infarct-related artery in selected patients before complete coronary angiography was associated with a benefit of 8 minutes in DTB time. Further study is required to determine whether this strategy can favorably affect clinical outcomes.Copyright © 2013. Published by Elsevier Inc.
