Abstract

Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) optimize percutaneous coronary intervention (PCI) by characterizing lesion morphology, accurately measuring vessel dimensions, and optimizing stent characteristics. We sought to compare the utilization of OCT and IVUS to guide inpatient PCI and their relative association with in-hospital mortality and readmission rates. We queried the National Readmission Database to identify patients undergoing intracoronary imaging-guided PCI from 2010 to 2019 and compared outcomes and readmission rates between patients undergoing OCT-guided PCI and IVUS-guided PCI. Multivariable logistic regression was performed to generate adjusted odds ratios (aOR) of adverse outcomes between the 2 groups. Of 3,71,450 intracoronary imaging-guided PCI admissions, OCT (n = 12,808) was used less frequently than IVUS (n = 358,642). The use of OCT-guided PCI increased from 0.1% in 2010 to 0.6% in 2019 while the rate of IVUS-guided PCI increased from 7.2% in 2010 to 9.4% in 2019 (both ptrend <0.001). Patients undergoing OCT compared to IVUS had lower in-hospital mortality (aOR 0.69, P = 0.015) and 30-day readmission rate (aOR 0.91, P = 0.040) with no statistical difference in 90-day readmission rate (aOR 0.93, P = 0.065). Heart failure was the most common cause of 30-day and 90-day readmissions in both cohorts. There was no difference in the rate of acute kidney injury between the 2 modalities. In this in-patient admission database of intracoronary imaging-guided PCI, OCT-guided PCI during index hospitalization appears to be associated with lower in-hospital mortality and 30-day readmission rates compared to IVUS-guided PCI with no difference in terms of the 90-day readmission rates.
