Difference between office and ambulatory blood pressure or real white coat effect

88 patients referred for hypertension

Measurement of real white coat effect using a Finapres device (expressed as maximal or average white coat effect)

Estimated white coat effect calculated as the difference between office blood pressure and ambulatory blood pressure (OBP-ABP)

Validity of the estimated white coat effect compared to the real white coat effect (magnitude, correlation, and agreement) and its association with target organ damage (left ventricular mass index, E to A mitral wave ratio, pulse wave velocity, serum creatinine, cholesterol, and glucose levels)surrogate
