ABSTRACT
OBJECTIVE:
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.METHODS:
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.RESULTS:
We recruited 5029 middle-aged and mainly defined WCH as SBP at least 140âmmHg and/or DBP at least 90âmmHg with HBP less than 135/85âmmHg. There were 2680 normotensive participants and 648 had WCH after exclusion of treated participants. More women (59.5%) than men (42.8%, Pâ<â0.001) had WCH. We found higher prevalence of CACS greater than 100 compared with less than 100 (12.4 vs. 7.2%, Pâ<â0.001), PWV (11.5â±â1.5 vs. 10.4â±â1.3âm/s, Pâ<â0.001) and a higher prevalence of one or more carotid plaques (59.5 vs. 48%, Pâ<â0.001) in participants with WCH than in normotension. Participants with WCH also had more dyslipidemia and higher glucose levels. Normotensive women scored lower on nervousness than women with WCH (Pâ=â0.022). After matching of 639 participants with WCH to normotensive participants according to age, gender and systolic HBP the prevalence of a high CACS (12.1 vs. 8.6%, Pâ=â0.003,) PWV (11.0â±â0.068 vs. 11.5â±â0.068âm/s, estimated marginal meansâ±âSE, Pâ<â0.001 by ANOVA) but not more carotid plaques (59.5 vs. 55.6%, Pâ=â0.23), remained in the participants with WCH compared with the matched normotensive participants.CONCLUSION:
WCH is particularly common in middle-aged women, and it displays metabolic dysfunction and increased prevalence of arteriosclerotic manifestations in both genders. As markers of increased cardiovascular risk were present also after matching normotensive and WCH participants according to systolic HBP, age and gender, the presence of WCH signals an increased cardiovascular risk burden that is not fully explained by elevated BP levels at home.
