Shorter reperfusion times in ST-elevation myocardial infarction (STEMI) are associated with improved survival. Prehospital strategies have been developed to minimize door-to-balloon (DTB) time, but few strategies within the catheterization laboratory itself have been evaluated. Incomplete angiography (IA) prior to percutaneous coronary intervention (PCI) is undertaken in clinical practice as a means to further reduce DTB time. We sought to determine whether or not those with STEMI who underwent IA prior to PCI had different preprocedural characteristics or post-PCI outcomes.
We retrospectively reviewed patients presenting to our institution between March 2013 and December 2015. Clinical, demographic, and angiographic data were reviewed. The frequency, predictors, and outcomes among those who received IA vs complete angiography (CA) prior to PCI were compared with analysis of variance.
Two hundred fifty-six patients were identified; 68 patients (26.6%) underwent IA and 188 patients (73.4%) had CA prior to PCI. Patients who received IA were younger, but no other preprocedural factors were predictive of IA. The practice of IA did vary by operator (range, 0%-47%; P<.01). DTB times were shorter in the IA group (28.1 min vs 37.3 min; P<.01). Overall outcomes, including peak troponin values, length of stay, in-hospital mortality, and discharge ejection fraction did not differ between the groups.
IA is associated with shorter DTB times, although in this population was not associated with improvements in short-term outcomes.
