Increasing evidences suggested that diabetes mellitus （DM） was a major risk factor for ISR, but the risk predictors of ISR in CAD patients with DM had not been well characterized. The aim of this study was to investigate the clinical and angiographic characteristic predictors significantly associated with the occurrence of ISR in diabetic patients following coronary stenting with drug-eluting stent （DES）. Methods A total of 920 patients with diabetes who diagnosed CAD and underwent coronary DES implantation at Beijing Anzhen Hospital in China were consecutively enrolled from January 2012 to December 2012. Of these, 440 patients underwent the second angiography within ≥ 6 months due to the progression of treated target lesions. Finally, 368 of these patients who met the inclusion and exclusion criteria were followed up by angiography after baseline PCI. According to whether ISR was detected at follow-up angiography, patients were divided into the ISR group （n = 74） and the non-ISR group （n = 294）. The independent predictors of ISR in patients with DM were explored by multivariate Cox＇s proportional hazards regression models. Results A total of 368 patients （260 women and 108 men） with a mean ages of 58.71 ± 10.25 years were finally enrolled in this study. Of these, ISR occurred in 74/368 diabetic patients （20.11%） by follow-up angiography. Univariate analysis showed that most baseline characteristics of the ISR and non-ISR group were similar. Patients in the ISR group had significantly higher serum very low density lipoprotein cholesterol （VLDL-C）, triglyceride （TG） and uric acid （UA） levels, more numbers of target vessel lesions, higher prevalence of multi-vessel disease, higher SYNTAX score, higher rate of previous but lower rate of drinking compared with patients in the non-ISR group. The independent predictors of ISR in patients with DM after DES implantation included VLDL-C （HR = 1.85, 95% CI： 1.24-2.77, P = 0.002）, UA （per 50 μmol/L increments, HR = 1.19, 95% CI： 1.05 1.34, P = 0.006）, SYNTAX score （per 5 increments, HR = 1.34, 95% CI： 1.03-1.74, P = 0.031） and the history ofPCI （HR = 3.43, 95% CI： 1.57-7.80, P = 0.003） by the multivariate Cox＇s proportional hazards regression analysis. Conclusions The increased serum VLDL-C and UA level, higher SYNTAX score and the history of previous PCI were independent predictors of ISR in patients with DM after coronary DES implantation. It provided new evidence for physi- cians to take measures to lower the risk oflSR for the better management of diabetic patients after PCI.展开更多

Methods Totally, 38 462 individuals who received health examination were enrolled in our study. We divided them into eight groups according to their ages. The levels of serum total cholesterol, triglyceride, high density lipoprotein cholesterol, and low density lipoprotein cholesterol were tested, and the relationship of blood lipid abnormity with body mass index (BMI) and fasting blood glucose was analyzed. Results The incidences of hypercholesterolemia, hyperglyceridemia, low high-density lipoprotein cholesterolemia, and hyper low-density lipoprotein cholesterolemia presented increasing trend in this population. The incidence rate of abnormity of blood lipid in health examination population increased with BMI increase. The incidence of abnormity of blood lipid in overweight and obesity population was significantly higher than that in low weight and normal weight populations (P<0.05). Meanwhile, the trend of abnormal blood lipid incidence coincided with that of abnormal fasting blood glucose. Conclusions The prevalence of overweight, obesity, and abnormity of blood lipid in Beijing presents increasing trend. The incidence of abnormity of blood lipid increases with BMI increase, in coincidence with that of fasting blood glucose.展开更多
