Assesment of the Effects of Smoking Cessation on some Hemorheologic Parameters

Background and Objectives: One of the imporant complications of smoking, is hemorheologic alteration. There is apparently increase in viscosity of plasma, total blood volume, and hemoconcentration in smokers, which may result in poor perfusion, leading to serious tissue damages. Materials and Methods: In order to evaluate whether these effects are reversible or not, two groups were studied: smokers determined to avoid smoking during Ramazan month (test group); and nonsmokers (control group). Each group consisted of 15 volunteers, and blood samples were taken before breaking their fast (Eftar) on 1st, 15th and 29th days of Ramazan month. Results: Whole blood and plasma viscosity, RBC count, WBC count, Hct, Hb concentrations and plasma fibrinogen, were measured. In nonsmokers, nonsignificant changes were found in the parameters mentioned above. In the test group, whole blood and plasma viscosity, fibrinogen concentrations and WBC count following 2nd and 4th weeks, and Hct, Hb concentrations, and RBC count following 4th weeks, decreased significantly. Conclusion: These findings suggest the reversibility of the hemorheologic alterations.
