Added value of aortic pulse wave velocity index for the detection of coronary heart disease by elective coronary angiography

Blood Pressure, 2019
Background: Non-invasive tests leading to elective coronary angiography (CAG) have low diagnostic yield for obstructive coronary heart disease (CHD). Aortic stiffness, an independent predictor of CHD events can be easily measured by pulse wave velocity ...
