Study debunks blood pressure testing theory
New research debunks the widely held belief that clinic readings tend to overestimate a person’s normal blood pressure.
In fact, the study suggests that about one in six people with normal clinic blood pressure has masked hypertension that can only be picked up through 24-hour monitoring.
The researchers describe this as the reverse of white coat hypertension.
Their study of almost 900 healthy middle-aged people found that 15.7% of participants with normal clinic blood pressure were actually hypertensive based on ambulatory monitoring, regardless of sex, race, or ethnicity.
And younger, normal-weight people were more likely than their older, overweight peers to have ambulatory blood pressure readings higher than their clinic readings.
