Participant milestones
| Measure |
Subjects With Spinal Cord Injury (SCI)
Subjects with SCI underwent a 45 degree head-up tilt maneuver to lower blood pressure and measure cerebral blood flow with and without enalaprilat (1.25 mg).
|
Subjects Without SCI (Non-SCI)
Subjects without SCI (non-SCI) underwent a 45 degree head-up tilt maneuver to lower blood pressure and measure cerebral blood flow with and without enalaprilat (1.25 mg).

Baseline characteristics by cohort
| Measure |
Subjects With Spinal Cord Injury
n=19 Participants
Subjects with spinal cord injury underwent a 45 degree head-up tilt maneuver to lower blood pressure and monitor cerebral blood flow on 2 study visits. The first visit subject underwent the head-up tilt maneuver without drug and on the second visits subject underwent the head-up tilt maneuver following oral administration of an angiotensin converting enzyme inhibitor (ACE: 1.25 mg enalaprilat).
|
Non-spinal Cord Injured Subjects
n=11 Participants
Non-spinal cord injured subjects underwent a 45 degree head-up tilt maneuver to lower blood pressure and monitor cerebral blood flow on 2 study visits. The first visit subject underwent the head-up tilt maneuver without drug and on the second visits subject underwent the head-up tilt maneuver following oral administration of an angiotensin converting enzyme inhibitor (ACE: 1.25 mg enalaprilat).
