Symptom Recognition Is Impaired in Patients With Orthostatic Hypotension, 2020, Freeman et al.

Abstract:

The magnitude of the SBP fall (r=−0.07, P=NS) and the lowest upright SBP (r=0.08, P=NS) did not correlate with any reported symptom. These results suggest a poor relationship between the magnitude of the orthostatic BP fall, the upright orthostatic BP, and symptoms. Many patients are asymptomatic despite substantial SBP falls and low orthostatic blood pressures. These findings have implications for clinical care of patients with OH and clinical trials to treat patients with OH.
