Abstract:
Objective To evaluate the rationale of lowering the cutoff value of impaired fasting glucose(IFG)by studying the extent and severity of angiographic coronary artery disease(CAD)and the cardiovascular risk factors in subjects with different fasting plasma glucose(FPG)levels. Methods A total of 911 consecutive patients who had undergone coronary angiography were selected according to inclusion criteria. The subjects were studied in view of the extent and severity of angiographic CAD and the cardiovascular risk factors with different FPG levels. Results (1) Compared with the group of FPG<5.6mmol/L, the numbers of diseased vessels in the group with FPG 5.6-6.0mmol/L were significantly increased(P<0.05)after adjustment of age, sex and other influencing factors; the group with FPG 6.1-6.9mmol/L had both raised number of diseased vessels and the CAD Gensini cumulative index(P<0.01). (2) The prevalences of overweight, hypertension, hypertriglyceridemia, metabolic syndrome were progressively increasing with graded FPG levels. The prevalence of hypertriglyceridemia was significantly increased with FPG level at 5.0-5.6mmol/L(P<0.05),and the prevalences of metabolic syndrome and other components were significantly elevated with FPG level at 5.6-6.0mmol/L(P<0.05). Conclusion (1) The extent and severity of angiographic CAD were increased with increased FPG even in prediabetic period. The risk of angiographic CAD became increased significantly with FPG at 5.6-6.0mmol/L level. (2) The cardiovascular disease(CVD)risk was also increased with increasing FPG even in prediabetic period. The phenomenon of clustering of CVD risk factors was found at FPG 5.6mmol/L.
