"In terms of white coat hypertension, we do know that having white coat hypertension is not something to ignore and I actually recommend treating people even with white coat hypertension because getting blood pressures in the 150's at any time are not good."
"The guidelines here in the US for blood pressure are < 140/90 or if you have diabetes or chronic kidney disease < 130/80."
"I go with the literature suggesting white coat hypertension can lead to true hypertension and I think if it is a person who consistently struggles with anxiety, stress, panic attacks, I would treat them."
