- Patients deserve to be medically optimised for treatment of metabolic risk factors and hypertension before referral for elective coronary artery bypass grafting (CABG). We describe here a prospective study of 347 consecutive patients referred for elective CABG. An oral glucose tolerance test (OGTT) was performed and metabolic risk factors and hypertension were determined pre-operatively. Compliance to treatment guidelines was calculated. From the total of 347 patients, 80 patients (23%) had known and 66 (19%) had previously unknown diabetes. Dysglycaemia (that is, diabetes and pre-diabetes) was found in 194 (73%) of the 267 patients without known diabetes. Among patients with dysglycaemia, 111/274 (41%) received one antihypertensive medication, or none, and blood pressure guidelines were met in 39/274 (14%); statins were being taken by 206 (75%; average dose 23 mg simvastatin) and low-density lipoprotein (LDL)-cholesterol guidelines were met in 43 (16%). In conclusion, diabetes diagnosis and titration of risk factor treatment to guidelines is inadequate even in elective CABG patients. A pre-admission OGTT affords an opportunity to improve care significantly.

- The primary objective of this study was to classify patients with CAD as regards their gluco-metabolic state by easily available clinical variables. A secondary objective was to explore if it was possible to identify CAD patients at a high cardiovascular risk due to metabolic perturbations. The 1,867 patients with CAD were gluco-metabolically classified by an OGTT. Among these, 990 patients had complete data regarding all components of the metabolic syndrome, BMI, HbA1c and medical history. Only FPG and HDL-c adjusting for age significantly impacted OGTT classification. Based on these variables, a neural network reached a cross-validated misclassification rate of 37.8% compared with OGTT. By this criterion, 1,283 patients with complete one-year follow-up concerning all-cause mortality, myocardial infarction and stroke (CVE) were divided into low- and high-risk groups within which CVE were, respectively, 5.1 and 9.4% (p=0.016).Adjusting for confounding variables the relative risk for a CVE based on the neural network was 2.06 (95% CI: 1.18—3.58) compared with 1.37 (95% CI: 0.79—2.36) for OGTT. Conclusions:The neural network, based on FPG, HDL-c and age, showed useful risk stratification capacities; it may, therefore, be of help when stratifying further risk of CVE in CAD patients.

- Abnormal glucose metabolism and type 2 diabetes mellitus (T2DM) are becoming increasingly common. It has been recently confirmed that the period of time prior to the development of diabetes, when patients have impaired glucose tolerance, may also predispose them to increased cardiovascular risk. Therefore prevention and management of T2DM and its antecedents must have high priority when allocating healthcare resources. The present review summarises some information on detection, management and treatment of abnormal glucose metabolism in patients with established coronary artery disease, highlighting the importance of early detection of abnormal glucose metabolism in order to prevent the progression of prediabetes to T2DM and to delay the occurrence of those macrovascular and microvascular complications that impair quality of life and diminish survival.

- To investigate whether sitagliptin affects copeptin and osmolality, suggesting arginine vasopressin activation and a potential for fluid retention, compared with placebo, in patients with a recent acute coronary syndrome and newly discovered type 2 diabetes or impaired glucose tolerance. A second aim was to confirm whether copeptin correlated with insulin-like growth factor binding protein-1. Methods: Fasting blood samples were used from the BEta-cell function in Glucose abnormalities and Acute Myocardial Infarction trial, in which patients recently hospitalized due to acute coronary syndrome and with newly detected abnormal glucose tolerance were randomized to sitagliptin 100 mg once daily ( n = 34) or placebo ( n = 37). Copeptin, osmolality and insulin-like growth factor binding protein-1 were analysed at baseline and after 12 weeks. Results: Copeptin and osmolality were unaffected by sitagliptin. There was no correlation between copeptin and insulin-like growth factor binding protein-1. Conclusion: Sitagliptin therapy does not appear to be related to activation of the arginine vasopressin system.

- Acute coronary syndromes are associated with a high risk for subsequent major cardiovascular events and with a risk for mortality that remains substantially increased for many months following the acute phase. Patients with type 2 diabetes mellitus are especially vulnerable and encounter excessive long-term mortality. Effective management of patients with type 2 diabetes following acute coronary syndromes requires aggressive multidisciplinary efforts for reduction of several risk factors, including meticulous control of blood glucose. The evidence for different medication and treatment strategies capable of improving the outcomes is reviewed and the currently available recommendations are summarised.

- Observations of increased stiffness in the elastic aorta in women with diabetes, but not men, emphasise the need for further analysis regarding early abnormalities in arterial wall properties of women with type 1 diabetes mellitus (DM).Ultrasound was used to study the wall properties of the distal brachial artery (BA) in 37 type 1 diabetic women (aged 22-45 years) without evident complications and in 53 controls (C). Blood samples were drawn for later analysis.Flow-mediated dilatation (FMD) was slightly lower in DM than C, 8.1 +/- 4.3% vs. 10.3 +/- 4.9% (p<0.05), and nitrate-mediated dilatation (NMD) was markedly lower, 21.7 +/- 6.6% vs. 31.4 +/- 5.7% (p<0.001). Lumen diameter, intima-media thickness and distensibility were similar in DM and C. Insulin-like growth factor (IGF-1) was lower in DM than C, 231 +/- 65 vs. 349 +/- 68 ng/ml (p<0.001). Glycosylated haemoglobin (HbA(1C)) and matrix metalloproteinase (MMP-9) were independent predictors of the reduced NMD in the DM.Brachial artery responsiveness to an exogenous donor of nitric oxide (NO) was markedly reduced in type 1 diabetic women despite only limited reduction in endothelium-dependent dilatation. The negative association between NMD and HbA(1C) suggests that long-term hyperglycaemia impairs vascular smooth muscle cell function in DM.

- AIMS: Despite vast clinical experience linking diabetes and atherosclerosis, the molecular mechanisms leading to accelerated vascular damage are still unclear. Here, we investigated the effects of nuclear factor of activated T-cells inhibition on plaque burden in a novel mouse model of type 2 diabetes that better replicates human disease.METHODS & RESULTS: IGF-II/LDLR-/-ApoB100/100mice were generated by crossbreeding low-density lipoprotein receptor-deficient mice that synthesize only apolipoprotein B100 (LDLR-/-ApoB100/100) with transgenic mice overexpressing insulin-like growth factor-II in pancreatic β cells. Mice have mild hyperglycaemia and hyperinsulinaemia and develop complex atherosclerotic lesions. In vivo treatment with the nuclear factor of activated T-cells blocker A-285222 for 4 weeks reduced atherosclerotic plaque area and degree of stenosis in the brachiocephalic artery of IGF-II/LDLR-/-ApoB100/100mice, as assessed non-invasively using ultrasound biomicroscopy prior and after treatment, and histologically after termination. Treatment had no impact on plaque composition (i.e. muscle, collagen, macrophages). The reduced plaque area could not be explained by effects of A-285222 on plasma glucose, insulin or lipids. Inhibition of nuclear factor of activated T-cells was associated with increased expression of atheroprotective NOX4 and of the anti-oxidant enzyme catalase in aortic vascular smooth muscle cells.CONCLUSION: Targeting the nuclear factor of activated T-cells signalling pathway may be an attractive approach for the treatment of diabetic macrovascular complications.

- Hyperglycaemia and glucose degradation products (GDPs) are closely associated with oxidative stress and inflammation in diabetic patients, a condition that leads to endothelial dysfunction and cardiovascular problems. We evaluated the effect of citrate and gluconate on glucose- and GDP-induced endothelial inflammation by measuring changes in viability, inflammation and function in primary human umbilical vein endothelial cells (HUVECs). The extent of apoptosis/necrosis was measured by flow cytometry and visualised with confocal microscopy by staining with annexin V or propidium iodide, respectively. Protein kinase C-βII (PKC-βII) activation was evaluated with Western blotting. Incubation with glucose (30 mM) and GDP (50 µM) significantly increased PKC-βII expression, endothelial cell death and inflammation. The addition of citrate decreased hyperglycaemia-induced apoptosis (p = 0.021), necrosis (p = 0.04) and reduced PKC-βII expression (p = 0.021) down to background levels. Citrate improved endothelial function by reducing the inflammatory markers(p = 0.01) and by decreasing neutrophil diapedesis (p = 0.012). These results suggest that citrate may have therapeutic potential by reducing hyperglycaemia-induced endothelial inflammation and abolishing endothelial dysfunction.

- To study the clinical characteristics related to metabolic disorders and complications in type 2 diabetes mellitus patients hospitalized in the Qingdao Endocrine and Diabetes Hospital from 2006 to 2012 in Qingdao, China. Patient population and methods: Data from 14,289 (51% males) type 2 diabetes mellitus patients hospitalized between 2006 and 2012 were collected and analysed. Information on patients’ demographic, anthropometric, laboratory and disease histories were extracted from electronic medical records. Results: The mean age of the patients was 60.5 years, with median diabetes duration of 9.0 years. Mean haemoglobin A1c was 8.4%, where <30.0% of patients had haemoglobin A1c <7.0%. In all, 34.5% of patients had low-density lipoprotein cholesterol lower than 2.6 mmol/L and 31.9% had hypertriglyceridaemia. Retinopathy was diagnosed in 51.1% of patients, nephropathy in 21.6%, neuropathy in 50.4%, hypertension in 77.4%, coronary heart disease in 27.6% and peripheral vascular disease in 58.6%. Once hospitalized, 71.1% of patients underwent insulin injection treatments, either mono-therapy or combined with other anti-diabetic drugs. Metformin was prescribed to 36.9% of patients, followed by acarbose 29.9%, thiazolidinediones 18.1%, meglitinides 14.8% and sulfonylureas 10.7%. Conclusion: Inadequate control of hyperglycaemia, poor metabolic profiles and diabetic complications were common challenges for long-term diabetes management in Chinese patients with type 2 diabetes mellitus.

- Objectives: Assess the effect of risk factors changes on risk for cardiovascular disease and mortality in patients with type 2 diabetes selected from the Swedish National Diabetes Register. Methods: Observational study of 13,477 females and males aged 30-75years, with baseline HbA1c 41-67mmol/mol, systolic blood pressure 122-154mmHg and ratio non-HDL:HDL 1.7-4.1, followed for mean 6.5years until 2012. Four groups were created: a reference group (n=6757) with increasing final versus baseline HbA1c, systolic blood pressure and non-HDL:HDL cholesterol during the study period, and three groups with decreasing HbA1c (n=1925), HbA1c and systolic blood pressure (n=2050) or HbA1c and systolic blood pressure and non-HDL:HDL (n=2745). Results: Relative risk reduction for fatal/nonfatal cardiovascular disease was 35% with decrease in HbA1c only (mean 6 to final 49mmol/mol), 56% with decrease in HbA1c and systolic blood pressure (mean 12 to final 128mmHg) and 75% with combined decreases in HbA1c, systolic blood pressure and non-HDL:HDL (mean 0.8 to final 2.1), all p<0.001 adjusting for clinical characteristics, other risk factors, treatments and previous cardiovascular disease. Similar risk reductions were found for fatal/nonfatal coronary heart disease, fatal cardiovascular disease, all-cause mortality and also in a subgroup of 3038 patients with albuminuria. Conclusion: Considerable risk reductions for cardiovascular disease and mortality were seen with combined long-term risk factor improvement.
