  Fig. 1. Trend in the number of percutaneous coronary interventions for myocardial infarction from 2008 to 2019, The bar graphs illustrate the number of PCIs performed for myocardial infarction from 2008 to 2019. Fig. 1A represents all PCIs, and the red line depicts the number of PCIs per 100,000 persons in the U.S. population. Fig. 1B represents IVUS-guided PCIs, and the red line shows the percent of IVUS-guided PCIs in all PCIs. Fig. 1C represents OCT-guided PCIs, and the red line shows the percent of OCT-guided PCIs in all PCIs. Abbreviations: IVUS = intravascular ultrasound; OCT = optical coherence tomography; PCI = percutaneous coronary intervention; U.S. = United States.

  Fig. 2. Use of intravascular imaging across different races, hospitals, primary payer, and income, The bar graphs show the frequency of intravascular imaging, consisting of either intravascular ultrasound or optical coherence tomography, across different races (Fig. 2A), hospital regions (Fig. 2B), hospital bed sizes (Fig. 2C), hospital urban locations (Fig. 2D), primary payers (Fig. 2E), and median income quartiles (Fig. 2F).

  Fig. 3. Total hospital cost of percutaneous coronary intervention for acute myocardial infarction, The line graphs show the total hospital costs for all PCIs, unadjusted (red) and adjusted for inflation (orange); IVUS-guided PCIs, unadjusted (blue) and adjusted for inflation (sky blue); and OCT-guided PCIs, unadjusted (green) and adjusted for inflation (yellow green) from 2008 to 2019. Asterisks (*) at the end of the graphs denote significant P-trend less than 0.001. Abbreviations: IVUS = intravascular ultrasound; OCT = optical coherence tomography; PCI = percutaneous coronary intervention.
