Analysis of the relationship between the amplitude of aortic wall motion and heart function.

Purpose: Because the posterior wall of the aorta and left atrium are interlocked, the amplitude of motion of the aortic wall (AMAW) may reflect cardiac and vessel functions. This study examined the relationship between cardiac and vessel functions and AMAW.

Methods: Patients with cardiovascular diseases or patients undergoing health examinations who visited a participating hospital and underwent echocardiography and brachial-ankle pulse-wave velocity (baPWV) examinations were registered.
