The smokers group was divided into four different categories depending on the number of cigarettes smoked per day. Several parameters were evaluated by B-mode and pulsed Doppler images acquired in longitudinal and transverse sections of the common carotid arteries: intima-media thickness (IMT), peak systolic velocity (PSV) and end-diastolic velocity (EDV). Our results suggest that smoking has negative effects on carotid artery structure and haemodynamics, and female smokers are more likely to develop vascular changes. Smoking is a risk factor for alterations in carotid artery haemodynamics.engjournal article
