Ventricular-arterial coupling during exercise and tilt assessed using a pulse wave velocity-to-global longitudinal strain ratio

Ventricular-arterial coupling (VAC) is commonly assessed using the echocardiography-derived ratio of arterial elastance to end-systolic elastance (E a /E es ), a convenient but global construct that collapses ventricular and arterial properties into a single lumped parameter. A p...
