We propose a consensus definition of "an exaggerated orthostatic pressor response" in subjects in whom systolic blood pressure increases ≥ 20 mmHg when going from supine to standing posture. This definition can be extended for seated to standing measurements. We reserve the term "orthostatic hypertension" for when this pressor response leads to an upright systolic blood pressure ≥ 140 mmHg. We believe this consensus definition will help in the study of the pathophysiology, clinical impact, and potential treatment of these entities, and identification of patients who are at greater cardiovascular risk.
