Smoking and cholesterol levels are two important components of atherosclerosis. Mean platelet volume (MPV) is an indicator of platelet function and activation and a potential marker of cardiovascular disease. In this study, we aimed to investigate the effects of cigarette-smoking on platelet count, MPV and cardiovascular risk factors.


This research was planned as a case-control study. Patients who attended our family medicine outpatient clinic were included in the study. Sociodemographic characteristics, smoking status, hematological and biochemical parameters of the patients were recorded.


The mean age of 880 patients who participated in the study was 35.85±11.6 years (17-77). 54.5% (n=480) of participants were smokers and 45.5% (n=400) were non-smokers. The number of smokers among working individuals was higher than in non-workers. The white blood cell, hemoglobin, hematocrit, red blood cell, mean corpuscular volume and MPV values in the smokers were higher than in the non-smokers, while platelet count was higher in non-smokers (p<0.001). There was a statistically significant relationship between MPV levels and the number of daily cigarette smoking among smokers (p=0.014).


MPV levels in smokers were significantly higher than in non-smokers. Platelet count and MPV levels should be investigated in larger patient groups in terms of atherosclerosis and other defined cardiovascular risk factors. It is therefore should take its rightful place in clinical practice.
