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.

White coat hypertension may be associated with:[1]

  • "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.[2]

White coat hypertension may be associate with anxiety (at least in women)[3], obstructive sleep apnea[2], and metabolic syndrome[4].

Although most patients with white coat hypertension are males, a greater proportion of women with hypertension have white coat hypertension than males with hypertension.[5]

Treatment

Because of the association with metabolic syndrome, one treatment option is metformin.[4]

Prognosis

White coat hypertension may evolve into sustained hypertension.[6][7]

Cardiovascular risks may[8] or may not[9] after 10 years of observation.
