Key result
Higher heart rate-adjusted augmentation index (AIx@75) was independently associated with an increased likelihood of undergoing percutaneous coronary intervention (OR 1.048) in patients with suspected coronary artery disease.
Why the study?
Does the augmentation index predict the need for percutaneous coronary intervention in patients with suspected CAD and high Framingham risk scores?

Augmentation index adjusted for heart rate (AIx@75) is associated with clinical CAD severity and the need for revascularization in high-risk patients.
Choi et al. (2015) conducted an observational in Suspected coronary artery disease (n=232). Higher heart rate-adjusted augmentation index (AIx@75) vs. Lower AIx@75 was evaluated on Percutaneous coronary intervention (PCI) (OR 1.048, 95% CI 1.009-1.088, p=0.015). Higher heart rate-adjusted augmentation index (AIx@75) was independently associated with an increased likelihood of undergoing percutaneous coronary intervention (OR 1.048) in patients with suspected coronary artery disease.
