Hypertension and Ventricular-Arterial Uncoupling in Collegiate American Football Athletes.

Background Ventricular-arterial (VA) coupling is defined as the ratio between arterial elastance (EA) and left ventricular elastance (ELV). VA uncoupling, as occurs in hypertensive heart disease, is associated with adverse outcomes. This study sought to determine the relationship between American football (AF)-associated hypertension and VA uncoupling.
