Masked hypertension is highly prevalent (approximately 33%) among African Americans with normal clinic blood pressure and is associated with greater target organ damage.
In this population-based cohort of African Americans, approximately one-third of participants with presumably normal clinic BP had masked hypertension when BP was assessed in their daily environment. Masked hypertension was accompanied by a greater degree of TOD in this cohort.
Diaz et al. (Fri,) studied this question.
