PURPOSE: Smoking is a significant risk factor of cardiac ischaemia. Changes in platelet count, morphology and platelet activation enhance the risk. MATERIAL AND METHODS: The objective of the study was to assess platelet parameters in smoking healthy subjects with reference to sex. In the group of women, 27% were smokers, in the group of men--49%. All the subjects were tested for platelet count (PLT), mean platelet volume (MPV), percentage of large platelets (L(PLT)), concentrations of beta-thromboglobulin, sP-selectin (soluble) and thrombopoietin, percentage of reticulated platelets (RP) and absolute count of reticulated platelet. RESULTS: Lower platelet count (237.00 +/- 39.52 vs 258.34 +/- 40.81 x 10(9)/l, p = 0.0002), higher percentage of reticulated platelets (1.39 +/- 0 .66 vs 1.04 +/- 0.35%, p = 0.04) and higher concentration of sP-selectin (52.66 +/- 18.54 vs 43.94 +/- 17.14 ng/ml, p = 0.03) were observed only in the group of smoking women, compared to non-smokers. In neither of the sexes smoking had an effect on the following parameters: mean platelet volume, percentage of large platelets, concentration of thrombopoietin, absolute count of reticulated platelet and concentration of beta1 -thromboglobulin. CONCLUSIONS: The results allow the hypothesis that women are more sensitive to smoking than men. Platelets in male smokers are less sensitive to smoking--the study showed no significant changes in the parameters.
