The white-coat effect, a rise in blood pressure in medical settings, is common in patients on antihypertensive therapy. This phenomenon impacts blood pressure management and requires clinical consideration.

Area of Science:

  • Cardiology
  • Hypertension Management

Background:

  • The white-coat effect (WCE) is a phenomenon where blood pressure is higher in a clinical setting than during ambulatory monitoring.
  • Understanding WCE prevalence in treated hypertensive patients is crucial for accurate diagnosis and management.

Purpose of the Study:

  • To determine the occurrence and prevalence of the white-coat effect in patients undergoing antihypertensive therapy.
  • To assess if WCE is more prevalent in specific demographic groups within treated hypertensive populations.

Main Methods:

  • A review of data from multiple studies investigating WCE in various patient populations receiving antihypertensive treatment.
  • Analysis of blood pressure readings (office vs. ambulatory) to identify instances of WCE (defined as office BP - ambulatory BP >= 20/10 mmHg).

Main Results:

  • In a tertiary care setting, 52 out of 71 treated hypertensive patients exhibited WCE.
  • A larger series confirmed this, with 106 of 152 treated patients showing WCE.
  • WCE was more frequent in women (70/87) than men (36/65) and also observed in untreated hypertensive patients (91/147).

Conclusions:

  • The white-coat effect is a common finding in patients receiving antihypertensive therapy.
  • Clinicians should consider WCE as a significant factor in the management of hypertension.
  • Further investigation into WCE in treated populations is warranted for optimized patient care.
