Trends in the use of diagnostic coronary angiography, percutaneous coronary intervention, and coronary artery bypass graft surgery across North Carolina

Although the use of all invasive cardiac procedures declined, the relative rate of PCI to Cath increased over the study period. There was also significant variation in the mode of revascularization (CABG and PCI) across hospital systems in North Carolina. Further research is needed to understand drivers of coronary revascularization.
