Relationships between cardiovascular risk factors and white-coat hypertension diagnosed by home blood pressure recordings in a middle-aged population

To study risk in white-coat hypertension (WCH) by measurement of coronary artery calcium score (CACS), carotid--femoral pulse-wave velocity (PWV) and carotid plaques. Cross-sectional population-based cohort with randomized selection of participants from Linköping, Sweden. An Omron m10-IT oscillometric device was used for clinic and home blood pressures (HBP) in the morning and evening for 1 week. We recruited 5029 middle-aged and mainly defined WCH as SBP at least 140 mmHg and/or DBP at least 90 mmHg with HBP less than 135/85 mmHg. There were 2680 normotensive participants and 648 had WCH after exclusion of treated participants. More women (59.5%) than men (42.8%, P
