Abstract: Background: Studies comparing inflammatory activity between diabetic and non diabetic individuals with acute coronary syndrome are scarce, and none including only patients with unstable angina (UA) has been published to date. Objective: We compared serum C-reactive protein (CRP), and interleukin-6(IL-6) between diabetic and non-diabetic patients with unstable angina (UA) to determine if difference in inflammatory activity is responsible for a worse prognosis in diabetic patients. We also evaluated the correlation between inflammatory markers and the metabolic profile in diabetic patients and the correlation between inflammatory response and in-hospital outcomes: death, acute myocardial infarction, congestive heart failure, and length of stay in hospital. Methods: A prospective cohort study of 90 consecutive patients admitted to a chest pain unit with UA and divided into two groups, diabetic and non-diabetic. Serum CRP, IL-6, metabolic profile and leukocyte count were measured at hospital arrival. Results: Forty-two patients (47%) were diabetic (age 62±9) vs. 48 (53%) non diabetic (age 63±12). No differences between median C-reactive protein (1.78 vs. 2.23mg/l,p=0.74) and interleukin-6 (0 vs. 0pg/ml,p=0.31) were found between the two groups. There was a positive correlation between CRP and total cholesterol (rs = 0.21,p = 0.05), CRP and LDL-cholesterol (rs=0.22,p=0.04) and between CRP and leukocyte count (rs = 0.32, p = 0.02) in both groups. No associations were found between inflammatory markers and in-hospital outcomes. Conclusion: We found no difference in inflammatory activity between diabetic and non diabetic patients with UA, suggesting that this clinical condition may result in balanced inflammatory activity between the two groups and increase acute-phase proteins independently of metabolic state.
