Key result
Recognizing symptoms during tilt testing for classical OH is linked to a ~12 mmHg greater BP fall.
Why the study?
Previous research regarding the association between blood pressure fall and symptoms yielded inconsistent results in classical orthostatic hypotension.
Does the magnitude of blood pressure fall correlate with symptom recognition in patients with classical orthostatic hypotension?
Population
77 tilt test records showing classical orthostatic hypotension
Comparison
40 with vs 37 without complaint recognition during tilt test
Design
Retrospective analysis

Symptom recognition may mark larger BP falls in cOH tilt tests; hypothesis-generating and requires prospective validation before practice change.
Observational (n=77)
Does the magnitude of blood pressure fall correlate with symptom recognition in patients with classical orthostatic hypotension?
Absolute Event Rate: 49.2% vs 37.3%
p-value: p=0.043
Symptom recognition during tilt testing in classical orthostatic hypotension is associated with a larger blood pressure fall and less total peripheral resistance increase, highlighting a complex pathophysiological relationship.
Gagaouzova et al. (2026) conducted an observational in Classical orthostatic hypotension (n=77). Complaint recognition during tilt test vs. No complaint recognition was evaluated on Blood pressure fall (p=0.043). Complaint recognition during tilt testing in classical orthostatic hypotension was associated with a larger blood pressure fall compared to asymptomatic cases (49.2 vs 37.3, p=0.043).
