Effect on door-to-balloon time of immediate transradial percutaneous coronary intervention on culprit lesion in ST-elevation myocardial infarction compared to diagnostic angiography followed by primary percutaneous coronary intervention.

Door-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
