Abstract:

Smoking and relation to other risk factors in postmenopausal women with coronary artery disease, with particular reference to whole blood viscosity and
-cell function. J Intern Med 2003; 253: 232239. Objectives. To investigate possible associations between smoking habits and other coronary risk factors in postmenopausal women with known coronary heart disease (CHD). Setting. The study was conducted at a university clinic. Subjects. A total of 118 postmenopausal women with CHD verified with angiography, consecutively recruited. Interventions. Conventional treatment for CHD. The women were randomized to hormone replacement therapy (HRT) with transdermal 17-
oestradiol and medroxyprogesterone acetate, or to a control group. Results. Smokers were younger (P = 0.005), had lower body mass index (P = 0.04) and lipoprotein Lp(a) levels (P = 0.02) compared with nonsmokers. Smokers had reduced
-cell function (homeostasis model assessment, P = 0.006), whereas whole blood viscosity (WBV) was higher at all shear rates. WBV was not affected by HRT over a 12-month period. Oestrone levels were higher in smokers. Conclusions. Smoking adversely affects insulin secretion (
-cell function) and WBV in postmenopausal women with established CHD, which could be of importance as a mechanism for the increased risk of CHD in smokers. The importance of smoking as a risk factor, overrides the effect of Lp(a), which is lower in smokers compared with nonsmokers.
