Blood pressure (BP) measured carefully by cuff under standardized conditions in physician offices has been shown to be an acceptable predictor of morbidity and mortality.1 However, 24-hour ambulatory BP monitoring is a closer surrogate end point for heart attack and stroke than office BP.2,3 Because the correlation between 24-hour ambulatory BP measurement and office BP measurement is moderate at best, not unexpectedly there will be a significant number of people who are truly hypertensive but in whom the diagnosis is missed by office BP measurements (masked hypertension). Conversely, BP may be elevated in the office but not on ambulatory BP monitoring, an entity known to most clinicians as white-coat hypertension.
Both masked hypertension and white-coat hypertension can be considered prehypertensive states not uncommonly evolving into sustained hypertension. The article by Mancia et al4 in the present issue of Hypertension assesses the risk of developing sustained hypertension in the Pressioni Arteriose Monitorate e Loro Associazioni population over a 10-year follow-up. Regardless of whether the definition of white-coat hypertension or masked hypertension was based on home BP measurements or 24-hour ambulatory monitoring, both forms of hypertension were at an increased risk of progressing to sustained hypertension. In fact, Mancia et al4 showed that >40% of patients having white-coat or masked hypertension will developed sustained hypertension over a 10-year period (Figure). In contrast, only 16% of truly normotensive subjects will progress to sustained hypertension within the same time span. Of note, both true normotensives and true hypertensive patients had the highest
