Outline of Final Research Achievements

On the basis of combined measurements of clinic blood pressure (CBP) and home BP (HBP), BP status can be divided into normotension (NT), white-coat hypertension (WCHT), masked HT (MHT), and sustained HT (SHT). The objective of this study was to investigate the associations of WCHT, MHT, and SHT with carotid atherosclerosis. This is a cross-sectional survey of 2915 community-dwelling Japanese aged ≧40 years. Mean intima-media thickness (IMT) of carotid arteries was measured using a computer-automated system, and carotid stenosis was defined as diameter stenosis ≧30%.
The geometric average of mean IMT was significantly higher among subjects with WCHT, MHT, and SHT than those with NT. Compared with NT, all types of HT were associated with increased likelihood of carotid stenosis. These associations remained significant even after adjustment for other cardiovascular risk factors. WCHT, as well as MHT, and SHT were associated with carotid atherosclerosis in a general Japanese population.
