Key result
Masked hypertension and sustained hypertension were associated with significantly greater carotid intima-media thickness (0.77 mm) compared to sustained normal blood pressure (0.71 mm) (P<0.0001).
Why the study?
Is masked hypertension associated with increased carotid atherosclerosis compared to normal blood pressure or white-coat hypertension?
Cross-Sectional (n=812)
Is masked hypertension associated with increased carotid atherosclerosis compared to normal blood pressure or white-coat hypertension?
Absolute Event Rate: 0.77% vs 0.71%
p-value: p=< 0.0001
Masked hypertension, detected by home blood pressure monitoring, is associated with increased carotid atherosclerosis similar to sustained hypertension, highlighting the inadequacy of casual clinic blood pressure alone for risk stratification.
No takes yet. Share an insight, caveat, or question.
Supports home BP monitoring to detect masked hypertension; leaves open whether it improves risk stratification prospectively.
Hara et al. (2007) conducted a cross-sectional in Masked hypertension and white-coat hypertension (n=812). Masked hypertension (MHT) vs. Sustained normal blood pressure was evaluated on Intima-media thickness (IMT) of the common carotid arteries (p=< 0.0001). Masked hypertension and sustained hypertension were associated with significantly greater carotid intima-media thickness (0.77 mm) compared to sustained normal blood pressure (0.71 mm) (P<0.0001).
