Behaviour of the carotid wall in menopausal women with and without arterial hypertension

Objective: A study was conducted on the carotid vascular wall to evaluate i ts behaviour in postmenopausal women suffering from arterial hypertension c ompared to normotensive postmenopausal women, Method: Intima-media thicknes s(IMT) of carotid artery was determined by ecoduplex scanner in 182 postmen opausal women (age range 40-60 years) divided in four age classes (40-45, 4 6-50, 51-55, 55-60 years). Ninety-one women presented normal arterial blood pressure (SBP 136.6 +/- 11.7 and DBP 82.3 +/- 8.9 mmHg) and 91 were hypert ensive (SBP 172.6 +/- 11.7 and DBP 97.4 +/- 6.6 mmHg). Results: The normote nsive women presented the following IMT values: 1.19 +/- 0.21 mm (40-45 yea rs), 1.21 +/- 0.25 mm (46-50 years), 1.25 +/- 0.20 mm (51-55 years), 1.25 /- 0.20 min (55-60 years). IMT values in hypertensive women were: 1.75 +/- 0.25 mm (40-45 years), 1.77 +/- 0.30 mm (45-50 years), 1.91 +/- 0.28 mm (51 -55 years), 2.02 +/- 0.33 mm (55-60 years). ANOVA test was performed in bot h groups of women and did not show any significant difference in the four a ge classes of normotensive women. On the other hand it revealed a statistic al significance between 40-45 and 46-59-year-old hypertensive classes (P < 0.001) and between 51-55 and 55-60-year-old hypertensive classes (P < 0.02) . Conclusions: There was a correlation between age and IMT in the arterial hypertensives, especially in two older classes, and between the duration of menopause and IMT values. The results indicated that carotid wall thickeni ng was constantly higher in hypertensive women compared with normotensive o nes. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
