White-coat hypertension (WCH), commonly found in pseudoresistant hypertension, does not pose higher cardiovascular risk than hypertensive status. However, when the decrease of the out-of-office blood pressure does not reach normal levels - the white-coat effect (WCE) - the repercussions are still obscure. We investigated the repercussions of the WCE in ...
