[Correlation of large artery stiffness and coronary flow velocity reserve].

Objective: Coronary flow velocity reserve (CFVR) is an important indicator of coronary endothelial functions and microcirculation. Pulse wave velocity (PWV) reflects the degree of aortic sclerosis and it is an independent predictor of cardiovascular events. The present study was designed to evaluate the correlation of large artery stiffness and CFVR.

[Left ventricular flow vector characteristics and the relationship between flow vector and left ventricular systolic function in patients with anterior myocardial infarction].

Objective: To assess left ventricular vortex and flow vector features and the relationship between vector flow and left ventricular systolic function in patients with anterior myocardial infarction by echocardiography-derived vector flow mapping (VFM).

Methods: Echocardiography was performed in 31 patients with anterior myocardial infarction and 20 healthy controls. Flow vector and velocity of left ventricle were analyzed on apical 3 chambers view with color Doppler.
