A new study published in JAMA Internal Medicine has found that blood pressure measurements performed within one minute of standing are the most strongly related to dizziness and individual adverse outcomes, such as risk of falls, fracture, syncope, motor vehicle crash, and mortality. Measurements obtained after one minute were not associated with dizziness and were inconsistently associated with individual long-term outcomes, suggesting that orthostatic hypotension (OH) should be assessed within one minute of standing
The findings are in contrast with current guidelines , which recommend assessing OH within three minutes of rising from supine to standing positions.
“Our findings suggest that a blood pressure assessment within the first minute is a better way to assess health risks due to orthostatic hypertension and that waiting three minutes might miss at-risk status,” said Dr Stephen Juraschek, lead author of the study. “If someone comes into the clinic with dizziness, we try to assess his/her risk of falling or other consequences of dizziness in the future. These results show that assessing OH within the first minute not only is OK, but also makes a lot of sense because it’s more predictive of future falls.”
