ABSTRACT
Objective:To observe the relationship between carotid intima-media thickness (CIMT) and hemoglobin A1c (HbA1c) control in type 2 diabetes mellitus (T2DM) patients.Methods:328 cases with T2DM were selected from the endocrinology department of our hospital.All patients underwent assessment,biochemical test and CIMT measurement.According to the value of CIMT,patients were divided into normal CIMT group (＜0.9 mm) and abnormal CIMT group (＞0.9 mm).A multi-factor Logistic regression was performed to analyze the risk factors associated with the abnormal CIMT.Results:(1) Among the 328 T2DM patients,154 cases had normal CIMT and 174 cases had abnormal CIMT.(2) Pearson correlation analysis indicated that the cholesterol and HbA1c levels were positively correlated with CIMT (P＜ 0.05).(3) Univariate analysis showed that the incidence of CIMT was associated with age (t=4.132,P=0.041),systolic blood pressure (t=8.456,P＜0.01),HbA1c≥ 9.0％ (x2=9.912,P＜0.01),cholesterol 0=5.549,P=0.018),triglyceride (t=6.592,P=0.008),UA(t=9.618,P＜0.01),fasting plasma glucose (t=4.592,P=0.037).(4) Multi-factor Logistic regression indicated that age,systolic blood pressure,cholesterol and HbA1c≥ 9.0％ were the independent risk factors for the onset of CIMT (P ＜0.05).Conclusions:The level of HbA1c in T2DM patients was associated with CIMT;And HbA1c≥ 9％ was the independent risk factors for the increase of CIMT.
