Abstract:
Objective To analyze the relation between glycosylated hemoglobin (HbA1c) and coronary heart disease (CHD) among diabetic and non-diabetic individuals.Methods A total of 1190 in patients from January 2009 to September 2009 were selected and divided into two groups:225 patients with diabete mellitus and 965 patients without.We collected the age,sex,triglyceride ( TG),total cholesterol ( CHO),high-density lipoprotein ( HDL-C),low-density lipoprotein ( LDL-C),fasting blood-glucose (FBG),glycosylated hemoglobin (HbA1c),high-sensitivity CRP (hs-CRP) and analyzed the relation between these indexes and CHD in diabetic and non-diabetic individuals respectively,then,analyzed the difference of HbA1c between patients with and without CHD after correcting the differentiating factor with a multivariable-adjusted model.Meanwhile,according the HbA1c level,we divided all participants into four groups:4.0％ -5.4％( Ⅰ),5.5％ -5.9％ ( Ⅱ),6.0％ -6.4％ ( Ⅲ),≥6.5％ ( Ⅳ),and observed the distribution of HbA1c and coronary heart disease in diabetic and non-diabetic individuals respectively.Results ( 1) In non-diabetic individuals,statistically significant difference of male( 80.5％ υs 62.7％),age [ ( 59 ±11) years υs (55 ± 11) years],FBG [(5.62 ± 1.48) mmol/L υs (5.30 ±0.84) mmol/L],HbA1c [(5.98±0.92)％ υs (5.65 ±0.53)％],CHO [(4.48 ±1.01) mmol/L υs (4.77 ±1.04) mmol/L],LDL-C [(2.59±0.87) mmol/L υs (2.79 ±0.86) mmol/L],HDL-C [(1.08 ±0.26) mmol/L υs(1.21 ±0.32) mmol/L] was observed between patients with and without CHD (P ＜0.01),however,in diabetic individuals,only LDL-C [ ( 2.56 ± 0.81) mmol/L υs ( 3.07 ± 0.90) mmol/L],CHO [ (4.44 ±0.95) mmol/L υs ( 5.08 ± 1.16) mmol/L] were observed ( P ＜ 0.0 1).(2) In all participants,the higher of HbA1c,the higher of CHD percent,compared to patients without CHD,the percent of high HbA1c in CHD patients was significantly higher.After adjusting for age,sex,HDL-C,HbA1c was an independent risk marker for CHD in non-diabetic individuals ( OR:1.935,95％ CI:1.356 - 2.762,P ＜ 0.05),however,links between FBG in the non-diabetic range and CHD appeared weaker after controlling indexes listed above( OR:1.507,95％CI:1.082 -2.098,P＜0.05).Conclusion HbA1c is an independent risk factor for CHD in nondiabetic individuals and prior to FBG.
