Aim: The cardio-ankle vascular index (CAVI) has been proposed as a new noninvasive marker of arterial stiffness independent of blood pressure VSports手机版. We investigated the association of the CAVI with coronary atherosclerosis and left ventricular (LV) systolic and diastolic function in patients with ischemic heart disease (IHD). .

Methods: A total of 206 consecutive subjects undergoing coronary angiography were enrolled. CAVI measurement and echocardiography were performed simultaneously V体育安卓版. Patients having significant coronary stenosis were classified into the IHD group. .

Results: CAVI in the IHD group (n=133) was significantly higher than in the non-IHD group(n=73)(9. 1+/-1. 3 vs. 8. 7+/-1. 2, p=0. 02) V体育ios版. In all IHD patients, CAVI was negatively correlated with LV ejection fraction (LVEF)(r=-0. 31, p<0. 01), LV mass index (r=0. 24, p<0. 01) and angiographic scores of coronary atherosclerosis. Stepwise regression analysis revealed that CAVI was independently associated with LVEF, along with a history of myocardial infarction, LV mass index, and left atrial diameter in all IHD patients (p<0. 01). In the sub-analysis of IHD patients with preserved LVEF, CAVI was correlated with echocardiographic parameters regarding LV diastolic function. Multivariate analysis demonstrated that the increased CAVI was significantly associated with LV diastolic dysfunction in patients with preserved LVEF. .

Conclusion: CAVI, a new parameter of aortic stiffness, was independently associated with LV systolic and diastolic function as well as coronary artery disease in IHD patients. VSports最新版本.
