| Abstract: | The clinical importance of white‐coat hypertension (WCH) remains a controversial issue. The aim of this study was to evaluate the association of isolated systolic, isolated diastolic, and systolic/diastolic WCH with common carotid artery intima‐media thickness (CCA‐IMT) and to compare each subgroup of WCH against other blood pressure (BP) phenotypes in terms of CCA‐IMT values. A total of 1382 consecutive patients underwent 24‐hour ambulatory BP monitoring and carotid artery ultrasonographic measurements. According to the type of elevated office BP, WCH was divided into three groups: isolated systolic, isolated diastolic, and systolic/diastolic WCH. Patients with isolated systolic WCH (n=112) had significantly higher CCA‐IMT values (0.737 mm) than those with isolated diastolic WCH (n=66) (0.685 mm) and nonsignificantly greater compared with those with systolic/diastolic WCH (n=228) (0.708 mm). Patients with isolated systolic WCH had CCA‐IMT values similar to those with hypertension, patients with isolated diastolic WCH had similar values to those with normotension, and patients with systolic/diastolic WCH had an intermediate risk between normotension and hypertension. |
