Key result
Spinal cord injury in rats reduced systolic blood pressure compared to baseline (p<0.003) and altered diurnal rhythms, with autonomic dysreflexia severity increasing from 14 days post-injury.
Why the study?
Does T3 spinal cord injury alter cardiovascular function and diurnal rhythms in male Wistar rats?
Does T3 spinal cord injury alter cardiovascular function and diurnal rhythms in male Wistar rats?
p-value: p=<0.003
Spinal cord injury induces rapid and profound alterations in basal hemodynamics and diurnal rhythms that partially recover by 14 days, while autonomic dysreflexia frequency and severity increase substantially from 14 days post-SCI.

Alerts preclinical SCI models to evolving BP instability and dysreflexia; leaves open human translation of diurnal changes.
West et al. (2015) studied Spinal cord injury (n=6). T3 spinal cord injury vs. Pre-injury baseline was evaluated on Cardiovascular response (arterial blood pressure, core body temperature, and heart rate) (p=<0.003). Spinal cord injury in rats reduced systolic blood pressure compared to baseline (p<0.003) and altered diurnal rhythms, with autonomic dysreflexia severity increasing from 14 days post-injury.
