Cardio-ankle vascular index relates to left ventricular ejection fraction in patients with heart failure. A retrospective study.


The cardio-ankle vascular index (CAVI) has been proposed as a new noninvasive marker of arterial stiffness independent of blood pressure. Arterial stiffness is closely related to afterload, and elevated afterload aggravates heart failure. We hypothesized that CAVI is a potential marker of afterload in patients with heart failure. Thirty patients who were… (More)
