White coat hypertension is a form of resistant hypertension in which the blood pressure is elevated when checked in the medical office but may be normal with ambulatory blood pressure monitoring or automated blood pressure determination[1].
Some patients may have their blood pressure rise by as much as 25 mm Hg due to an alarm reaction upon seeing a doctor (i.e., white coat hypertension).[2]
21% of patients with untreated borderline hypertension (diastolic pressure between 90 and 104 mm Hg) may have normal blood pressures outside of the doctor's office.[3]
White coat hypertension may be associated with:[4]
- "parallels the reactivity to mental stress and standing in hypertensive subjects"
- "likely results from a sympathetic nervous activation via a vasoconstrictor response rather than tachycardia"
- "decreased arterial distensibility"
However, patients with white coat hypertension do not have increased catecholamines.[5]
White coat hypertension may be associated with anxiety (at least in women)[6], obstructive sleep apnea[5], and metabolic syndrome[7].
Although most patients with white coat hypertension are males, a greater proportion of women with hypertension have white coat hypertension than males with hypertension.[3]
Treatment
Because of the association with metabolic syndrome, one treatment option is metformin.[7]
Prognosis
White coat hypertension may evolve into sustained hypertension.[8][9]
Cardiovascular risks may[10] or may not[11] after 10 years of observation.
