OBJECTIVE: To assess the impact of relationship between glycated hemoglobin (HbA(1c)), fibrinogen and HDL-cholesterol (HDL-c) on cardiovascular disease in type 2 diabetes. METHODS: We investigated i) the relationship of HbA1c, fibrinogen and HDL-c in 375 coronary artery disease (CAD)-negative and 320 CAD-positive diabetic patients and ii) the association between clustering of these three factors and incident major cardiovascular events in 317/320 CAD-positive patients. RESULTS: i) The relationships between HbA1c and both fibrinogen and HDL-c and between HDL-c and fibrinogen were significant only in CAD-positive patients (β = 10.655, p = 0.002; β = -1.056, p = 0.013; β = -1.751, p = 0.000008, respectively); ii) patients with worse-than-median levels of the three factors showed higher risk for major cardiovascular events than others (HR: 2.22, 95%CI = 1.23-4.02, p = 0.008). Both findings were independent of LDL-c, blood pressure or ongoing therapies. CONCLUSION: Our findings suggest interwoven actions of poor glycemic control, low grade inflammation and low HDL-c on atherosclerotic processes in type 2 diabetes.
