Key result
Isolated diastolic orthostatic hypotension is rare, accounting for only 5.4% of classical orthostatic hypotension cases, indicating that 94.6% of cases can be identified by the systolic criterion alone.

May streamline orthostatic hypotension screening to systolic criteria; leaves open prospective validation of simplified diagnostics.

An abnormal orthostatic fall in diastolic blood pressure without a fall in systolic blood pressure is rare, suggesting that approximately 95% of patients with classical orthostatic hypotension can be identified by the systolic criterion alone.
Fedorowski et al. (2017) conducted an observational in Suspected syncope and/or orthostatic intolerance (n=1,520). Diastolic blood pressure criteria for orthostatic hypotension vs. Systolic blood pressure criteria was evaluated on Prevalence of isolated diastolic orthostatic hypotension among patients meeting classical orthostatic hypotension criteria. Isolated diastolic orthostatic hypotension is rare, accounting for only 5.4% of classical orthostatic hypotension cases, indicating that 94.6% of cases can be identified by the systolic criterion alone.
