Why the study?
Does cardio ankle vascular index improve diagnostic accuracy for coronary artery disease compared to brachial ankle pulse wave velocity in patients with chest pain undergoing coronary angiography?
Population
696 patients with chest pain who underwent coronary angiography
Comparison
Cardio ankle vascular index (CAVI) measurement vs Brachial ankle pulse wave velocity measurement
Design
Cross-sectional

CAVI may aid CAD detection over baPWV in chest pain; leaves open prospective validation before any practice change.
Does cardio ankle vascular index improve diagnostic accuracy for coronary artery disease compared to brachial ankle pulse wave velocity in patients with chest pain undergoing coronary angiography?
The cardio ankle vascular index provides superior diagnostic accuracy over brachial ankle pulse wave velocity for predicting coronary artery disease, potentially due to its independence from blood pressure effects.
