In-hospital outcomes of angiography versus intravascular ultrasound-guided percutaneous coronary intervention in ST-elevation myocardial infarction patients

Background We compared the in-hospital complications, outcomes, cost, and length of stay (LOS) between angiography-guided percutaneous coronary intervention (PCI) and intravascular ultrasound (IVUS)-guided PCI in patients with ST-elevation myocardial infarction (STEMI) in the USA. Methods A nationwide inpatient database was queried to identify patients >18 years with STEMI who underwent angiography-guided and IVUS-guided PCI from January 2016 to December 2016. We compared the in-hospital mortality, complications, cost, and LOS between the two groups. Results We identified 100,485 patients who underwent angiography-guided PCI and 5,460 patients who underwent IVUS-guided PCI. In-hospital mortality was not statistically different (odds ratio [OR] 0.76, 95% CI 0.46 − 1.22, P = 0.24). Patients who underwent PCI with IVUS were more likely to have coronary artery dissection (OR 4.26, 95% CI 2.34 − 7.7, p =
