Abstract:
Objective To investigate risk factors for the progress of subclinical atherosclerosis (AS)in newly diagnosed type 2 diabetics with muhifactorial intervention.Methods One hundred and fifty- six patients of type 2 diabetes,aged 35～70 years,with course of less than one year and without subclinical AS,were observed prospectively.After two-year intervention based on anti-platelet therapy integrated with intensive control of blood glucose,blood lipid,blood pressure and body weight,dynamic changes in all metabolic indicators and subclinical AS in the patients and differences between those with subclinical AS and without it were analyzed to study the risk factors for its progress by logistic regression analysis.Results There were no significant differences in intima-medial thickness(IMT)of common carotid artery(CCA) and femoral artery(FA)in the patients between baseline and two years after intervention,but those in them were significantly increased two years after intervention than those one year after intervention(P＜0.O1). Two years after intervention,increased IMT or atherosclerotic plaques could be found in 45 of 156 patients (28.8%),significantly higher than those one year after intervention(11.5%,P＜0.01).Levels of glycosylated hemoglobin Alc(HbAlc),total cholersterol(TC),high-density lipoprotein-cholesterol (HDL-C)and HOMA-insulin resistance(IR)showed an increased trend two years after intervention,as compared with those one year after intervention(P＜0.01).Proportions of those with normal level of HbAlc two years after intervention was significantly lower than that one year after intervention(P＜0.01). Proportions of those with normal level of HbAlc and low-density lipoprotein-cholesterol(LDL-C)were significantly lower in patients with subclinical AS than those without it two years after intervention(P＜0.01).Logistic regression analysis showed that relative risk(RR)for subclinical AS could reduce by 83% with normal level of LDL-C and 59% by normal HbAlc,respectively,but there was an 82% increase in RR for it with an increase of age by ten years.Conclusions Subclinical AS could not be absolutely prevented in patients with newly diagnosed type 2 diabetics after two-year intensive multifactorial intervention.Subclinical AS could present a progressive trend with time,as well as levels of blood glucose and blood lipid.Levels of LDL-C and HbAlc,as well as age,were major risk factors for occurrence of subclinical AS in patients with newly-diagnosed type 2 diabetes.
