Associations of blood pressure with carotid intima-media thickness in elderly Finns with diabetes mellitus or impaired glucose tolerance

Journal of Human Hypertension volume 17, pages 705–711 (2003)Cite this article

Abstract

The aim of the present study was to evaluate the associations of ultrasonographic manifestations of carotid atherosclerosis with systolic (SBP) and diastolic blood pressure (DBP) and pulse pressure (PP) in 65-year-old Finns drawn from a population-based cohort. Carotid ultrasonographic measurements were performed on 54 diabetic subjects, 97 subjects with impaired glucose tolerance (IGT) and 57 normoglycaemic subjects (NGT). The subjects were classified into four quartiles of SBP, DBP and PP. SBP, DBP, PP and the use of antihypertensive drugs increased along with the deterioration of glucose status. The maximal intima-media thickness (IMT) of the common carotid artery (CCA) from the lowest to the highest quartiles of SBP was 0.98±0.34, 1.00±0.35, 1.03±0.29, 1.18± 0.52 mm (P=0.038), respectively. SBP was higher (161±22 mmHg) in the subjects with severe intima-media thickening (maximal IMT CCA ≥1.2 mm) than in those with maximal IMT CCA of <1.2 mm (153± 20 mmHg) (P=0.030). DBP and PP tended to be higher in the former than the latter group (DBP: 89±9 mmHg vs 86±9 mmHg, P=0.055 and PP: 72±18 mmHg vs 67±17 mmHg, P=0.159). The prevalence of severe intima-media thickening was 39% in the subjects in the highest SBP quartile (≥170 mmHg) and 20% in the subjects with lower SBP (P=0.008). In multiple regression analysis, the adjusted OR for severe intima-media thickening was 2.9 (95% CI 1.1–7.9) in the subjects in the highest SBP quartile compared to the subjects with lower SBP. In the present study, high SBP was associated with severe carotid intima-media thickening. We suggest that the results can be generalized to apply to elderly Finnish subjects with DM and IGT, but not to normoglycaemic subjects, on the basis of this study.
