Abstract
This study was designed to determine the clinical characteristics of hypertensive patients whose blood pressures are substantially higher in the medical office than in their natural environments. Thirty-nine percent of patients enrolled in a nonpharmacologic hypertension treatment program had systolic or diastolic office blood pressures (OBPs) that were at least 10 mm Hg higher than their ambulatory blood pressures (ABPs). Although these white-coat responders (WCRs) had higher systolic OBPs than did non-white-coat responders (NRs), both their systolic (p<0.02) and their diastolic (p<0.0001) ABPs were significantly lower than those of NRs. Furthermore, patients with white-coat hypertension did not have greater blood pressure reactivity in their natural environments, suggesting that their blood pressure elevations may be specific to the medical setting. White-coat hypertensives were older (p<0.005), had less angry dispositions (p<0.01), and reported less overt anger expression (p<0.005). They were also taking more antihypertensive medications than were the other patients in the study (p<0.001).
