Abstract

INTRODUCTION: Intravascular imaging-guided percutaneous coronary intervention (PCI) has shown to improve outcomes in randomized controlled trials. However, there are little real-world data about intravascular imaging utilization during PCI and its outcomes in the United States.

METHODS: We conducted an observational analysis on the use of intravascular imaging (Intravascular Ultrasound or Optical Coherence Tomography)-guided PCI in 2,425,036 patients undergoing PCI between January 2010 and December 2014 from the Nationwide Inpatient Sample database. Utilizing propensity score matching, 83,988 matched pairs were identified. The primary outcome was in-hospital mortality. The secondary outcomes included cardiogenic shock and acute kidney injury.

RESULTS: Among the 2,425,036 patients, 161,808 (6.7%) underwent imaging-guided PCI. Use of imaging-guidance increased from 6% in 2010 to 6.6% in 2014 (Ptrend < 0.001). The in-hospital mortality was significantly different between imaging-guided PCI and angiography-guided PCI [1.0% vs. 1.5%; adjusted OR: 0.67; 95% confidence interval (CI): 0.54-0.83, P < 0.001]. The rates of cardiogenic shock (2.5% vs. 3.1%; adjusted OR: 0.78; 95% CI: 0.66-0.93; P = 0.005) were significantly lower in imaging-guided PCI group and acute kidney injury rates (7.0% vs. 7.1%; adjusted OR: 0.99; 95% CI: 0.89-1.12; P = 0.919) were not significantly different.

CONCLUSIONS: Imaging-guided PCI is associated with lower in-hospital mortality. Yet, a small proportion of patients undergoing PCI have imaging-guidance.
