Abstract:

Cigarette smoking is well recognized as a major risk factor for atherosclerosis in men and women. Brachial flow-mediated dilation (FMD) is a physiologic measure and carotid intima-media thickness (IMT) is an anatomic structural measure of subclinical atherosclerosis. The purpose of this study was to observe the effects of cigarette smoking expressed in package-years on endothelial function evaluated by ultrasonographic measurement of brachial FMD and carotid IMT in four groups of subjects: arterial hypertension [HTN] group, atherogenic dyslipidemia [DYS] group, coronary artery disease, angiographically confirmed [BCV] group and [CON] group. Cigarette smoking, measured in package – years was significantly higher in [BCV] group compared to the [DYS] group (p<0.001), the [HTN] group (p<0.001) and the [CON] group (p<0.001). The forearm reactive hyperemic response (FMD) was significantly blunted in [BCV] group (p<0.001) compared to [HTN] group (p<0.001), [DYS] group (p<0.001) and to [CON] group (p<0.001). The patients from [BCV] group had highly significant greater IMT compared to patients from [HTN] group, [DYS] group and [CON] group (p<0.001). In our study, we observed that cigarette smoking induces a significant deterioration of endothelial dysfunction that is dependent of the number of package-years.
