Association of Early Hemodynamic Profile and the Development of Systolic Dysfunction Following Traumatic Brain Injury.

Patients who develop systolic dysfunction following TBI have a distinctive hemodynamic profile, with early hypertension and tachycardia, followed by a decrease in blood pressure over the first day after TBI. This profile suggests an early maladaptive catecholamine-excess state as a potential underlying mechanism of TBI-induced systolic dysfunction.
