Hemodynamic response pattern predicts susceptibility to stress-induced elevation in arterial pressure in the rat.

Abstract

Cocaine or air jet stress evokes pressor responses due to either a large increase in systemic vascular resistance (vascular responders) or small increases in both cardiac output and vascular resistance (mixed responders) in conscious rats. Repeated cocaine administration results in elevated arterial pressure in vascular responders but not in mixed… (More)
