title: Effect of repeated measurements of blood pressure on blood pressure in essential hypertension: role of anxiety.
abstract: Over the past years, we repeatedly observed that of the hypertensive population entered into our behavioral treatment programs, more than half were actually false hypertensives. With repeated measurements of blood pressure (BP), only one-third remained hypertensive, while two-thirds showed a significant decrease in BP. The purpose of this study was to determine which factors correlate with the decrease in BP and could be useful in distinguishing the true and the false hypertensives. Of the 24 patients in this study, 15 decreased their mean arterial pressure by at least 5 mm Hg during a 6-week period of home and clinic BP measurement, while 9 did not. The 9 patients with BPs that did not change had lower State Anxiety, Trait Anxiety scores, lower diastolic BP, and lower heart rates compared to the group whose BPs decreased. These results suggest that under certain conditions a relationship exists between anxiety and elevated blood pressure. In a segment of the hypertensive population, anxious patients may be placed on inappropriate antihypertensive medication if a BP measurement period is not conducted before intervention.
