Clinic BP measurements may miss many patients with masked
hypertension
Dr K K
Aggarwal, National President IMA
According to a new research published in
the journal Circulation, around the clock monitoring during daily activity
revealed masked, or undetected, high blood pressure among otherwise
healthy adults who had normal readings in the clinic.
In this study, researchers compared clinic
blood pressure measurements to ambulatory blood pressure monitoring in 888
healthy, middle-aged participants enrolled in the Masked Hypertension Study at
Stony Brook University and Columbia University in New York between 2005 and
2012. And 24-hour ambulatory BP monitoring during daily activities revealed
undetected high BP among otherwise healthy adults who had normal readings in
the clinic.
·
15.7% of study participants
with normal clinic BP had masked hypertension based on ambulatory monitoring,
regardless of sex, race, or ethnicity.
·
Younger, normal-weight
participants were more likely than older, overweight participants to have
ambulatory blood pressure readings higher than their clinic readings.
Based on these findings, the study authors
advise doctors to be aware of the fact that normal BP readings in the clinic
may not rule out high BP among otherwise healthy patients.
