Key result
White-coat hypertension is linked to preserved coronary flow reserve compared to sustained hypertension.
Why the study?
The influence of white-coat hypertension on coronary flow reserve was unclear.
Does white-coat hypertension affect coronary flow reserve compared to sustained hypertension and healthy volunteers?
Population
29 patients with white-coat hypertension, 32 with sustained hypertension, and 35 healthy volunteers
Comparison
White-coat hypertension vs sustained hypertension and healthy volunteers
Design
Cross-sectional study using transthoracic second harmonic Doppler echocardiography

Supports distinguishing WCH from sustained hypertension by preserved CFR; leaves open prognostic implications.
Cross-Sectional (n=96)
Does white-coat hypertension affect coronary flow reserve compared to sustained hypertension and healthy volunteers?
Absolute Event Rate: 2.77% vs 2.83%
Coronary flow reserve is preserved in patients with white-coat hypertension, unlike in sustained hypertension where it is reduced.
Doğan Erdoğan (2005) conducted a cross-sectional in White-coat hypertension (n=96). White-coat hypertension vs. Sustained hypertension and healthy volunteers was evaluated on Coronary flow reserve (CFR). White-coat hypertension was associated with a preserved coronary flow reserve (2.77), similar to healthy controls (2.83) and significantly higher than in sustained hypertension (2.40).
