[Ambulatory blood pressure monitoring to study white coat syndrome in patients with hypertension seen in primary care].

Introduction And Objectives: The white coat phenomenon is said to occur when the difference between systolic/diastolic blood pressure measured during visits to the doctor's office and in ambulatory recordings is greater than 20/10. These absolute differences, known as the white coat effect, may lead to normotensive patients being classified as having white coat hypertension (WCH). We used ambulatory blood pressure monitoring (ABPM) to monitor the prevalence and response (white coat effect, white coat hypertension or white coat phenomenon) in patients during pharmacological treatment for grade 1 or 2 hypertension, and 4 weeks after treatment was suspended under medical supervision.

[Influence on white coat effect and heart rate of antihypertensive agents used at a urban health center].

Background: We name white coat effect (WCE) to the difference between the systolic arterial pressure (SAP)/diastolic AP (DAP) of consulting room and the ambulatory obtained one with ambulatory blood pressure monitoring (ABPM). In our work we analyzed by means of ABPM, the influence of the antihypertensive medicaments on the WCE and the cardiac frequency of use of the antihypertensive ones.

Design: Almost experimental study (with a period before and a period later) and descriptive.
