BACKGROUND: Inflammation has been demonstrated to be an important risk factor for the development of cardiovascular disease (CVD). The relationship of the peripheral leukocyte count to the severity of stable angina remains to be clarified. The present study analyzed the relationship of the peripheral leukocyte count to the severity of stable angina determined by coronary angiography. METHODS: The data from 108 patients with stable angina, and 92 subjects with normal coronary angiograms were reviewed, and the role of the peripheral leukocyte count as a risk factor for stable angina evaluated. In addition, the correlation of the peripheral leukocyte count and the severity of stable angina, as assessed by the Gensini's score in the stable angina group, were analyzed. RESULTS: Age, the prevalence of hypertension and diabetes, and the fasting blood sugar were significantly higher, and the HDL was lower in the stable angina than the control group. A multivariate analysis showed that a peripheral leukocyte count over 6,800/mm3 was an independent variable, but with no statistical significance (p=0.067), and diabetes (OR=3.02, 95% CI: 1.29-7.02) and old age (OR=3.62, 95% CI: 1.3-9.87) were independent risk factors for stable angina. A positive correlation between peripheral leukocyte count and Gensini's score was noted in the stable angina group even after adjusting for age, fasting blood sugar, blood pressure and lipid profiles (R2=0.198, p=0.015). CONCLUSION: An increased peripheral leukocyte count is considered not so much an indicator of the pathogenesis of stable angina, but as a predictor for disease progression. Furthermore, it is considered that the above correlation will be helpful in screening high-risk groups that require relatively active interventional therapy.
