Association of History of Dizziness and Long-term Adverse Outcomes With Early vs Later Orthostatic Hypotension Assessment Times in Middle-aged Adults.

ABSTRACT:

Importance

Guidelines recommend assessing orthostatic hypotension (OH) 3 minutes after rising from supine to standing positions. It is not known whether measurements performed immediately after standing predict adverse events as strongly as measurements performed closer to 3 minutes.

Objective

To compare early vs later OH measurements and their association with history of dizziness and longitudinal adverse outcomes.

Design, setting, and participants

This was a prospective cohort study of middle-aged (range, 44-66 years) participants in the Atherosclerosis Risk in Communities Study (1987-1989).

Exposures

Orthostatic hypotension, defined as a drop in blood pressure (BP) (systolic BP ≥20 mm Hg or diastolic BP ≥10 mm Hg) from the supine to standing position, was me
