BACKGROUND: Epidemiologic studies have shown a correlation between white blood cell (WBC) count and risk of developing myocardial infarction. Aim of this study is to assess the association between WBC and the other risk factors of coronary heart disease in a southern Italian population. METHODS: Baseline data for the 1091 subjects (522 males and 569 females) enrolled in the "Montecorvino Rovella Project" were used to study factors associated with leukocytes. RESULTS:WBC count was significantly higher in smokers (8711.1 +/- 1892 cells/dl) than in ex-smokers (6720 +/- 1608 cells/dl) and in those who never smoked (6674 +/- 1608 cells/dl). By multiple linear regression analysis, WBC count showed a positive association with triglycerides (p < 0.01), cholesterol (p < 0.05) fasting glucose levels (p < 0.01) and diastolic blood pressure (p < 0.05). CONCLUSIONS: In this southern Italian population, elevated WBC count has been associated with other risk factors of coronary artery disease, particularly smoking, and has identified a high risk atherogenic profile. Even if the independency of the role of WBC is still under investigation, WBC count should be taken into account in establishing the coronary risk of apparently healthy people.
