Coronary flow reserve is preserved in white-coat hypertension

Abstract

Objectives: To assess the possible influence of white-coat hypertension (WCH) on coronary flow reserve (CFR).

Methods: CFR was measured by means of transthoracic second harmonic Doppler echocardiography in 29 patients with WCH, 32 patients with sustained hypertension and 35 healthy volunteers.

Results: CFR was significantly lower in the sustained hypertension group than in the WCH and the control groups, but it was not different between the WCH and the control groups (2.40 (SD 0.54), 2.77 (0.41) and 2.83 (0.60), respectively).

Conclusion: CFR is preserved in patients with WCH.

  • ABPM, ambulatory blood pressure monitoring
  • BP, blood pressure

  • LAD, left anterior descending coronary artery
  • TTDE, transthoracic second harmonic Doppler echocardiography
  • WCH, white-coat hypertension
  • Doppler echocardiography
  • coronary circulation
  • target-organ damage
  • white-coat hypertension
