Abstract
BACKGROUND Determining the relationship between cardiovascular risks, carbohydrate metabolism disorders, and renal dysfunction can help in creating new tools for their management and for better interaction of specialists in a multidisciplinary team. The purpose of this study was to determine the functional state of the kidneys and carbohydrate metabolism in patients with acute coronary syndrome without a history of such disorders. METHODS 200 patients of the cardiology department of the City Clinical Hospital No. 7 in Almaty were examined using laboratory diagnostics and subsequent statistical data processing. RESULTS Acute coronary syndrome develops in 63% of cases against the background of previous disorders of carbohydrate metabolism - prediabetes (45.5%) and type 2 diabetes mellitus (17.5%). In this group of patients, in the presence of disorders of carbohydrate metabolism, in all cases, it is accompanied by acute renal damage. It was noted that diabetes mellitus in newly diagnosed patients actually had a certain duration and occurred much earlier than cardiovascular complications - this was evidenced by an increased level of glycated hemoglobin. CONCLUSIONS Such results indicate the need for early diagnosis of cardio-reno-metabolic syndrome in patients with cardiovascular complications, as well as timely administration of drugs that simultaneously have antidiabetic, cardio- and nephroprotective effects.

Diabetes Metab Syndr Obes 2023; 16:2733-2744. [PMID: 37706215 PMCID: PMC10496847 DOI: 10.2147/dmso.s425960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 08/29/2023] [Indexed: 09/15/2023] Open
Abstract
Purpose The aim of this study was to evaluate whether intervention by clinical pharmacists can improve blood glucose and lipid levels in diabetic patients with complex medical conditions. Methods The retrospective database included 138 patients with diabetes who had presented with acute myocardial infarction (AMI) between January 2019 and October 2021. Blood glucose and lipid levels were measured within 12 weeks and 78 weeks of follow-up. Propensity score matching (PSM) was used to balance the confounding effects of patients' characteristics. Results A total of 138 eligible patients were assigned to either the intervention group (n = 47) or the usual care group (n = 91). After the intervention, there were significant improvements in blood glucose (glycosylated hemoglobin-HbA1C % from 9.0 to 8.3; fasting blood glucose-FBG mmol/L from 11.3 to 7.1; postprandial blood glucose-PBG mmol/L from 17.0 to 12.1; p < 0.001) and lipid levels (total cholesterol-TC from 4.9 to 3.5, low-density lipoprotein cholesterol-LDL-C from 3.0 to 1.8, p < 0.001, mmol/L) in both follow-up periods. The blood glucose effects were most pronounced in the PBG control rate (76.9% vs 54.0%) before PSM, while HbA1C% and PBG control rate after PSM were significantly higher in the intervention group (HbA1C% rate: 65.6% vs 38.5%; PBG rate: 79.2% vs 45.8%; p < 0.05, intervention vs non-intervention). Subgroup analysis further confirmed the improvement of blood glucose and lipid mainly in patients with higher baseline FBG (≧10mmol/L) and moderate follow-up duration (4-12 weeks). Conclusion The intervention of clinical pharmacists in multidisciplinary team can significantly improve blood glucose and lipid levels in complex type 2 diabetic patients, especially those with high baseline FBG and moderate follow-up durations.

Abstract
Background Prediabetes is a disordered state of glucose metabolism defined by an elevated blood glucose level that is below the level required for the diagnosis of diabetes. Prediabetes is associated with an increased risk of cardiovascular disease. The onset and progression of macrovascular disease occur during the prediabetes phase. Early diagnosis and screening of prediabetes are essential steps to prevent diabetes and its associated complications. Objective To assess the prevalence of prediabetes and undiagnosed diabetes in patients with cardiovascular disease according to the ADA criteria. Methods This cross-sectional study included 2968 a high cardiovascular risk patients aged 40 to 75 years admitted to the Department of Internal Medicine. Sociodemographic variables and other relevant medical history information were collected by the researchers during the clinical interview. A fasting blood sample was obtained to determine HbA1c levels and other relevant laboratory findings. Results Of the total number of participants, 1496 participants were not diagnosed with diabetes, 485 (32.4%) of them had HbA1c values indicating prediabetes and 158 (10.6%) of them had HbA1c values indicating new diagnosed diabetes. Up to one-third of those with undiagnosed prediabetes had already been diagnosed with cardiovascular complications. Conclusion Routine screening of glycemic metabolism could be valuable in identifying high-risk individuals before a cardiovascular event occurs.

Admission glucose as a prognostic marker for all-cause mortality and cardiovascular disease. Cardiovasc Diabetol 2022; 21:258. [PMID: 36435766 PMCID: PMC9701417 DOI: 10.1186/s12933-022-01699-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 11/16/2022] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Diabetes and prediabetes are known risk factors for cardiovascular disease and associated with increased mortality risk. Whether patients with a random elevated blood glucose level but no history of diabetes are at a higher mortality and cardiovascular risk is not entirely known. METHODS A retrospective cohort study where patients (18-80 years) with no history of diabetes between 2006 and 2016 attending the emergency department (ED) in Sweden were included. Based on the first (index) blood glucose level patients were categorized into four groups: hypoglycemia (< 3.9 mmol/L), normal glucose tolerance (NGT) (3.9-7.8 mmol/L), dysglycemia (7.8-11.1 mmol/L), and hyperglycemia (> 11.1 mmol/L). Data was collected from four nationwide registers (National Patient Register, National Cause of Death Register, Prescribed Drug Register and Statistics Sweden). Cox regression was used to calculate adjusted hazard ratios (HR) with 95% confidence intervals (CI) for all-cause mortality and cardiovascular outcomes using NGT as reference. RESULTS 618,694 patients were included during a mean follow-up time of 3.9 years. According to the index blood glucose level: 1871 (0.3%) had hypoglycemia, 525,636 (85%) had NGT, 77,442 (13%) had dysglycemia, and 13,745 (2%) patients had hyperglycemia, respectively. During follow-up 44,532 (7.2%) deaths occurred. After multiple adjustments, mortality risk was highest in patients with hypoglycemia HR 2.58 (2.26-2.96) followed by patients with hyperglycemia HR 1.69 (1.63-1.76) and dysglycemia HR 1.16 (1.13-1.19). Risk for cardiovascular events: i.e., myocardial infarction, stroke and heart failure, were highest among patients with hyperglycemia HR 2.28 (2.13-2.44), HR 1.62 (1.51-1.74) and HR 1.60 (1.46-1.75), respectively. CONCLUSION Patients with disturbed blood glucose level at ED admission have a higher mortality risk than patients with NGT. Patients with hyperglycemia have almost a two folded increased long-term mortality risk and more than a doubled risk for cardiovascular events compared to patients with NGT.

Life (Basel) 2022; 12:life12111945. [PMID: 36431080 PMCID: PMC9699150 DOI: 10.3390/life12111945] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 11/01/2022] [Accepted: 11/18/2022] [Indexed: 11/23/2022] Open
Abstract
Glycosylated hemoglobin (HbA1c) is an established marker associated with cardiovascular risk, even if it is below the diagnostic threshold for diabetes mellitus (DM). However, whether or not prediabetic and controlled diabetic levels of HbA1c are associated with increased major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI) remains unclear. This observational study included a total of 9128 patients who underwent PCI in the COACT registry from eight centers in Korea. A total of 2517 non-DM patients were divided into three groups (Groups I, II, III) according to their HbA1c levels and compared with 965 controlled DM patients (HbA1c < 7.0%, Group IV). During 22 months of median follow-up, there was no significant differences in MACE (p = 0.294) and cardiac death (p = 0.105) among the four groups. In addition, there were also no significant differences in MACE (p = 0.058) between Group III and Group IV. Although patients were diagnosed as DM, they had a similar prognosis in the same range of newly diagnosed DM patients in HbA1c, if they were treated well. The results of this study suggest that intensive treatment is required to reach the Hba1c target in diabetic patients with PCI in order to have a similar prognosis to patients not previously diagnosed with diabetes.

Abstract
AIMS/HYPOTHESIS Established dysglycaemia (impaired glucose tolerance [IGT] or type 2 diabetes [T2DM]) is a risk factor for further cardiovascular events in patients with coronary artery disease. Sodium-glucose cotransporter 2 inhibitors reduce this risk. The aim of the present investigation was to test the hypothesis that empagliflozin exerts beneficial effects on myocardial function in patients with a recent acute coronary syndrome and newly detected dysglycaemia. METHODS Forty-two patients (mean age 67.5 years, 81 % male) with recent myocardial infarction (n = 36) or unstable angina (n = 6) and newly detected IGT (n = 27) or T2DM (n = 15) were randomised to 25 mg of empagliflozin daily (n = 20) or placebo (n = 22) on top of ongoing therapy. They were investigated with oral glucose tolerance tests, stress-perfusion cardiac magnetic resonance imaging (CMR) and echocardiography at three occasions: before randomisation, after seven months on study drug and three months following cessation of such drug. Primary outcome was a change in left ventricular (LV) end-diastolic volume (LVEDV) and secondary outcomes were a change in a) systolic and diastolic LV function; b) coronary flow reserve; c) myocardial extracellular volume (ECV) in non-infarcted myocardium; d) aortic pulse wave velocity. RESULTS Empagliflozin induced a significant decrease in fasting and post load glucose (p < 0.05) and body weight (p < 0.01). Empagliflozin did not influence LVEDV, LV systolic or mass indexes, coronary flow reserve, ECV or aortic pulse wave velocity. Echocardiographic indices of LV diastolic function (E/e' and mitral E/A ratio) were not influenced. No safety concerns were identified. CONCLUSIONS/INTERPRETATION Empagliflozin had predicted effects on the dysglycaemia but did not influence variables expressing LV function, coronary flow reserve and ECV. An explanation may be that the LV function of the patients was within the normal range.

Abstract
Disparities in cardiovascular outcomes are persistent in our society. The objective was to track the trends before and after the passage of the Affordable Care Act in socioeconomic status (SES) disparities in utilization of cardiovascular disease (CVD) preventive services among nonelderly adults aged 18-64 years. This study used the National Health Interview Survey (2011-2017) to compare utilization of blood pressure, cholesterol, glycemic screening, and diet and smoking cessation advice over time between groups stratified by SES and race using difference-in-difference analysis. This study also measured the differences over time in specific vulnerable population subgroups (Hispanic, low-income and uninsured vs. White, middle-high-income, and insured). The study population included 176,961 surveyed individuals (mean age 40 [±13] years; 51% female; 67.7% non-Hispanic White) between 2011 and 2017, translating to 194.8 million nonelderly US adults per year. Most individuals were from high-income SES (40.0%), followed by middle-income (28.1%), low-income (13.6%), and lowest income SES (18.3%). The proportion of CVD preventive services increased over all SES categories through the study period. The biggest relative changes were seen among low-income individuals. The difference in blood pressure checks, cholesterol checks, and smoking cessation advise between high- and lowest income groups showed a statistically significant decrease at 5.2%, 4.8%, and 11.2%, respectively, between 2011 and 2017. The findings demonstrate a trend in reduction of CVD preventive care disparities between SES groups. However, a gap still exists, and this study highlights the need for continuous improvement to eliminate SES disparities.

Abstract
Diabetes and prediabetes (called abnormal glucose regulation (AGR)) are adverse health effects associated with exposure to pesticides. However, there are few epidemiological studies on the relationship between pesticide use and the incidence of AGR. We examined the causal relationship between pesticide use and AGR incidence in a rural population using data from a Korean Farmers’ Cohort study of 1076 participants. Poisson regression with robust error variance was used to calculate the relative risks (RR) and 95% confidence intervals (CI) to estimate the relationship between pesticide exposure and AGR. The incidence of AGR in the pesticide-exposed group was 29.1%. Pesticide use increased the RR of AGR (RR 1.32, 95% CI 1.03–1.69). We observed a low-dose effect related to exposure of pesticides to AGR and a U-shaped dose–response relationship in men. Pesticide exposure is related to the incidence of AGR, and the causal relationship differs between men and women.

Brown adipose tissue prevents glucose intolerance and cardiac remodeling in high-fat-fed mice after a mild myocardial infarction. Int J Obes (Lond) 2022; 46:350-358. [PMID: 34716427 PMCID: PMC8794788 DOI: 10.1038/s41366-021-00999-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 10/11/2021] [Accepted: 10/13/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Obesity increases the risk of developing impaired glucose tolerance (IGT) and type 2 diabetes (T2D) after myocardial infarction (MI). Brown adipose tissue (BAT) is important to combat obesity and T2D, and increasing BAT mass by transplantation improves glucose metabolism and cardiac function. The objective of this study was to determine if BAT had a protective effect on glucose tolerance and cardiac function in high-fat diet (HFD) fed mice subjected to a mild MI. METHODS Male C57BL/6 mice were fed a HFD for eight weeks and then divided into Sham (Sham-operated) and +BAT (mice receiving 0.1 g BAT into their visceral cavity). Sixteen weeks post-transplantation, mice were further subdivided into ±MI (Sham; Sham-MI; +BAT; +BAT-MI) and maintained on a HFD. Cardiac (echocardiography) and metabolic function (glucose and insulin tolerance tests, body composition and exercise tolerance) were assessed throughout 22 weeks post-MI. Quantitative PCR (qPCR) was performed to determine the expression of genes related to metabolic function of perigonadal adipose tissue (pgWAT), subcutaneous white adipose tissue (scWAT), liver, heart, tibialis anterior skeletal muscle (TA); and BAT. RESULTS +BAT prevented the increase in left ventricle mass (LVM) and exercise intolerance in response to MI. Similar to what is observed in humans, Sham-MI mice developed IGT post-MI, but this was negated in +BAT-MI mice. IGT was independent of changes in body composition. Genes involved in inflammation, insulin resistance, and metabolism were significantly altered in pgWAT, scWAT, and liver in Sham-MI mice compared to all other groups. CONCLUSIONS BAT transplantation prevents IGT, the increase in LVM, and exercise intolerance following MI. MI alters the expression of several metabolic-related genes in WAT and liver in Sham-MI mice, suggesting that these tissues may contribute to the impaired metabolic response. Increasing BAT may be an important intervention to prevent the development of IGT or T2D and cardiac remodeling in obese patients post-MI.

Abstract
BACKGROUND Although acute hyperglycemia and insulin resistance (IR) are risk factors for atherosclerosis development through oxidative stress and sympathetic activation in diabetes mellitus, the association of these factors with coronary microvascular function in the early diabetic stage remains controversial.Methods and Results:Using transthoracic echocardiography, coronary flow velocity (CFV) and its reserve (CFVR) as parameters of coronary microvascular function were measured before and 1 h after an oral glucose tolerance test (OGTT) in 40 patients (aged 59±12 years) without diagnosed diabetes mellitus or coronary artery disease. Plasma glucose, insulin and thiobarbituric acid reactive substance (TBARS; an oxidative stress marker) were measured during the OGTT. IR was evaluated as homeostasis model assessment of IR (HOMA-R). Sympathetic activity was evaluated by using plasma catecholamines after OGTT. CFVR decreased after an OGTT (P<0.0001) mainly because of an increased baseline CFV (P<0.0001). Although the change in CFVR was not associated with the change in TBARS and catecholamines, it was independently associated with HOMA-R on the multivariate regression analysis (β=-0.40, P=0.01). Another multivariate regression analysis revealed that change in baseline CFV was independently associated with HOMA-R (β=0.35, P=0.03). CONCLUSIONS IR, rather than oxidative stress and sympathetic activity, was associated with an increase in baseline CFV and a decline in CFVR during acute hyperglycemia. IR might play an important role in increased myocardial oxygen demand and coronary microvascular dysfunction.

Abstract
BACKGROUND Risk stratification of patients with prediabetes is an unmet clinical need. Here, we examine the utility of subclinical myocardial necrosis assessed by high-sensitivity cardiac troponin T (hs-cTnT) in predicting health outcomes in stable subjects with prediabetes. METHODS hs-cTnT was analyzed by a high-sensitivity assay (Roche 5th generation) in 2631 stable subjects with prediabetes (HbA1c 5.7-6.4% or fasting glucose 100-125 mg/dL without previous diagnosis of diabetes or glucose-lowering therapy) who underwent elective coronary angiography for cardiac evaluation, and followed for major adverse cardiac events (MACE; death, myocardial infarction, stroke) over 3 years and all-cause mortality over 5 years. RESULTS In our study cohort, hs-cTnT was highly prevalent with a median level of 13 ng/L (interquartile range 8.2-21.6 ng/L). Hs-cTnT was independently associated with incident MACE at 3 years (Q4 vs. Q1 adjusted hazard ratio (HR) 2.42 [95% CI 1.69-3.46], P < 0.001) and 5-year mortality (adjusted HR 3.8 [95% CI 2.55-5.67], P < 0.001). This association remained significant in all subsets after adjustment for traditional risk factors and multiple factors known to increase hs-cTnT levels. Moreover, hs-cTnT independently predicted event risk in primary prevention subjects (n = 557, HR 5.46 [95% CI 1.50-19.89), p < 0.01) for MACE; HR 9.53 [95% CI 2.08-43.73] for all-cause mortality) and secondary prevention subjects (n = 2074, HR 1.86 [95% CI 1.31-2.66], P < 0.001 for MACE; and 2.7 [95% CI 1.79-4.08), P < 0.001 for all-cause mortality). CONCLUSIONS In stable prediabetic subjects, the presence of subclinical myocardial necrosis as detected by hs-cTnT portends heightened long-term adverse cardiovascular event risk. Hs-cTnT levels may help to stratify risk and improve clinical decision making in patients with prediabetes. Trial registration ClinicalTrials.gov Identifier: NCT00590200.

Abstract
Background Fasting plasma glucose (FPG) and 2-h post challenge plasma glucose (2 h-PCPG), whether as continuous or categorical variables, are associated with incident cardiovascular disease (CVD) and diabetes; however, their role among patients with existing CVD is a matter of debate. We aimed to evaluate associations of different glucose intolerance states with recurrent CVD and incident diabetes among subjects with previous CVD. Methods From a prospective population-based cohort, 408 Iranians aged ≥ 30 years, with history of CVD and without known diabetes were included. Associations of impaired fasting glucose (IFG) according to the American Diabetes Association (ADA) and World Health Organization (WHO) criteria, impaired glucose tolerance (IGT), newly diagnosed diabetes (NDM) with outcomes of interest were determined by multivariable Cox proportional hazard models after adjustment for traditional risk factors. Furthermore, FPG and 2 h-PCPG were entered as continuous variables. Results Over a decade of follow-up, 220 CVD events including 89 hard events (death, myocardial infarction and stroke) occurred. Regarding prediabetes, only IFG-ADA was associated with increased risk of hard CVD [hazard ratio(HR), 95%CI: 1.62,1.03–2.57] in the age-sex adjusted model. In patients with NDM, those with FPG ≥ 7 mmol/L were at higher risk of incident CVD/coronary heart disease(CHD) and their related hard outcomes (HR ranged from 1.89 to 2.84, all P < 0.05). Moreover, those with 2 h-PCPG ≥ 11.1 mmol/L had significant higher risk of CVD (1.46,1.02–2.11), CHD (1.46,1.00–2.15) and hard CHD (1.95:0.99–3.85, P = 0.05). In the fully adjusted model, each 1 SD increase in FPG was associated with 20, 27, 15 and 25% higher risk of CVD, hard CVD, CHD and hard CHD, respectively; moreover each 1 SD higher 2 h-PCPG was associated with 21% and 16% higher risk of CVD, and CHD, respectively. Among individuals free of diabetes at baseline (n = 361), IFG-ADA, IFG-WHO and IGT were significantly associated with incident diabetes (all P < 0.05); significant associations were also found for FPG and 2 h-PCPG as continuous variables (all HRs for 1-SD increase > 2, P < 0.05). Conclusions Among subjects with stable CVD, NDM whether as high FPG or 2 h-PCPG, but not pre-diabetes status was significantly associated with CVD/CHD and related hard outcomes.

Abstract
BACKGROUND Disturbances of glucose metabolism can be diagnosed by an oral glucose tolerance test (OGTT) and by glycated haemoglobin (HbA1c). The aim of this study was to investigate the association between newly detected disturbances of glucose metabolism and long-term prognosis after acute myocardial infarction (AMI) and to compare the predictive value of an OGTT and HbA1c. METHODS Patients under the age of 80 years with no known history of diabetes admitted for AMI at the Department of Cardiology, Danderyd University Hospital, Stockholm, Sweden, from January 1st, 2006 until December 31st, 2013, were investigated with an OGTT and a HbA1c before discharge and were classified as having normal glucose tolerance (NGT), prediabetes or diabetes according to American Diabetes Association (ADA) criteria. Using nationwide, all-inclusive registers, patients were followed for the incidence of combined event [CE (first of myocardial infarction, heart failure, ischaemic stroke or mortality)] for a mean follow-up time of 4.8 years. Cox regression analysis was used to calculate Hazard Ratios (HR) and their 95% confidence intervals (CI). RESULTS Of the 841 patients who were investigated with both an OGTT and a HbA1c, 139 (17%) patients had NGT, 398 (47%) had prediabetes and 304 (36%) had diabetes according to OGTT. The corresponding figures using HbA1c were 320 (38%), 461 (55%) and 60 (7%). Patients with newly discovered diabetes were older and had a higher body mass index compared to those with NGT. OGTT was not predictive for CE. In contrast, prediabetes identified by a HbA1c was associated with an increased risk for CE (HR 1.31; 95% CI 1.05-1.63) compared to normoglycaemia. When comparing the prognostic value of different glucose and HbA1c cut-offs, only a HbA1c ≥ 39 mmol/mol was significantly associated with CE (HR 95% CI; 1.30:1.05-1.61). CONCLUSION In this single-centre study, in a recent contemporary cohort, we found that around two thirds of the patients admitted with AMI with no known history of diabetes had disturbed glucose metabolism, in accordance with previous studies. HbA1c in the prediabetes range, but not OGTT, added predictive value on the long-term outcome, in a cohort to whom a pathologic OGTT result was communicated with lifestyle advice.

Comparative evaluation of metformin and liraglutide cardioprotective effect in rats with impaired glucose tolerance. Sci Rep 2021; 11:6700.

Abstract
Impaired glucose tolerance (IGT) increases cardiovascular risk and can enlarge myocardial infarction (MI) incidence and severity. There is lack of information about cardioprotective potential of glucose-lowering drugs in IGT. We aimed to evaluate the sustainability of myocardium to ischemia-reperfusion injury in diabetic and IGT rats and to study cardioprotective action of metformin and liraglutide. Type 2 diabetes mellitus (DM) and IGT were modelled in Wistar rats by high-fat diet and streptozotocin + nicotinamide. 4 weeks after rats were divided into 4 groups: DM (without treatment) (n = 4), IGT (without treatment) (n = 4), IGT + MET (metformin 200 mg/kg per os once daily 8 weeks) (n = 4), IGT + LIRA (liraglutide 0.06 mg/kg s.c. once daily for 8 weeks) (n = 4). Control (n = 6) and high-fat diet (n = 8) groups were made for comparison. After 8 weeks ischemia-reperfusion injury in isolated hearts was performed. Hemodynamic parameters were evaluated and MI size was measured by staining of myocardium slices in triphenyltetrazolium chloride solution. Blood glucose level was measured during the study. Both IGT and DM led to similar worsening of hemodynamic parameters during ischemia-reperfusion period, in comparison with control group. MI size in IGT (56.76 (51.58; 69.07) %) and DM (57.26 (45.51; 70.08) %) groups was significantly larger than that in control group (42.98 (33.26; 61.84) %) and did not differ between each other. MI size in high-fat diet group (56.98 (47.11; 62.83) %) was as large as in IGT and DM groups (p > 0.05). MI size in IGT + MET (42.11 (38.08; 71.96) %) and IGT + LIRA (42.50 (31.37; 60.40) %) was smaller than in both DM and IGT groups (p < 0.05 for multiple comparison). Myocardium damage size did not differ in IGT + MET and IGT + LIRA groups (p > 0.05). Only LIRA, but not MET administration to IGT rats led to ischemic contracture reduction. Glycemic control was similarly satisfactory in IGT, IGT + MET, IGT + LIRA groups. Thus, IGT and DM have similarly pronounced negative influence on hemodynamics and MI size in rat transient global ischemia ex vivo. Obesity development also has negative impact on the MI size. Both MET and LIRA have infarct-limiting effect independent on their influence on glucose level. LIRA, but not MET, diminishes ischemic contracture in IGT rats.

Abstract
BACKGROUND The effect of postload glucose spikes (PGS), the difference between 2 hour post-load plasma glucose (2hPLPG) and fasting plasma glucose (FPG), on post-myocardial infarction (post-MI) prognosis in nondiabetic patients is unexplored. METHODS This is a retrospective cohort analysis of 847 nondiabetic post-MI survivors who underwent a predischarge oral glucose tolerance test (median PGS: 2.4 mmol/L). Patients were divided into the unmatched groups 1 and 2 (PGS ≤ and > 2.4 mmol/L) and the propensity score-matched groups 1M and 2M (355 pairs assembled from the overall cohort), and these groups were compared. Major adverse cardiac events (MACE: death and nonfatal reinfarction) were recorded during follow-up (median: 3.4 years). Event-free survival was compared by the Kaplan-Meier method. Multivariate Cox proportional hazards regression determined the predictors of MACE. C-statistics (change in area under the curve, δAUC), continuous net reclassification improvement (NRI>0 ), and integrated discrimination improvement (IDI) were used to compare models. RESULTS The number of MACE was higher in groups 2 (27.3% vs 14.2%, P < .001) and 2M (24.5% vs 15.5%, P < .001). Event-free survival was worse in groups 2 (hazard ratio [HR] 2.01; 95% CI, 1.49-2.71; P < .001) and 2M (HR 1.63; 95% CI, 1.17-2.27; P = .004). PGS independently predicted MACE-free survival in the whole (HR 1.16; 95% CI, 1.06-1.26; P = .002) and matched cohort (HR 1.12; 95% CI, 1.02-1.24; P = .021). PGS, but not FPG or 2hPPG, improved the predictive performance of the base model (δAUC 0.013, P = .046), with greater improvement seen when PGS was added and compared to 2hPPG (δAUC 0.005, P = .034; NRI>0 0.2107, P = .013; IDI 0.0042, P = .046). CONCLUSION PGS is a better predictor of post-MI prognosis than 2hPPG in nondiabetic patients.

Abstract
Background Diabetes is an increasingly important risk factor for ischemic stroke and worsens stroke prognosis. Yet a large proportion of stroke patients who are eventually diabetic are undiagnosed. Therefore, it is important to have sensitive assessment of unrecognized hyperglycaemia in stroke patients. Design Secondary outcome analysis of a randomized controlled trial focussing on parameters of glucose metabolism and detection of diabetes and prediabetes in patients with acute ischemic stroke (AIS). Methods A total of 130 consecutively admitted patients with AIS without previously known type 2 diabetes mellitus (T2DM) were screened for diabetes or prediabetes as part of secondary outcome analysis of a randomized controlled trial that tested lifestyle intervention to prevent post-stroke cognitive decline. Patients had the oral glucose tolerance test (OGTT) and glycated hemoglobin (HbA1c) measurements in the second week after stroke onset and after 1 year. The detection rates of diabetes and prediabetes based on the OGTT or HbA1c values were compared. Results By any of the applied tests at the second week after stroke onset 62 of 130 patients (48%) had prediabetes or T2DM. Seventy-five patients had results from both tests available, the OGTT and HbA1c; according to the OGTT 40 (53.3%) patients had normal glucose metabolism, 33 (44%) had prediabetes, two (2.7%) T2DM. In 50 (66.7%) patients the HbA1c results were normal, 24 (32%) in the prediabetic and one (1.3%) in the diabetic range. The detection rate for disorders of glucose metabolism was 10% higher (absolute difference; relative difference 29%) with the OGTT compared with HbA1c. After 1 year the detection rate for prediabetes or T2DM was 7% higher with the OGTT (26% relative difference). The study intervention led to a more favourable evolution of glycemic status after 1 year. Conclusion The OGTT is a more sensitive screening tool than HbA1c for the detection of previously unrecognized glycemic disorders in patients with acute stroke with an at least a 25% relative difference in detection rate. Therefore, an OGTT should be performed in all patients with stroke with no history of diabetes. Trial registrationhttp://clinicaltrials.gov. Unique identifier: NCT01109836.

Abstract
BACKGROUND Impaired glucose tolerance (IGT) in patients with ischemic stroke can return to normal, reflecting an acute stress response, or persist. Persistent IGT is associated with an increased risk of recurrent stroke, other cardiovascular diseases and unfavorable outcome after stroke. We aim to validate our previously developed model to identify patients at risk of persistent IGT in an independent data set, and, if necessary, update the model. METHODS The validation data set consisted of 239 nondiabetic patients with a minor ischemic stroke or TIA and IGT in the acute phase (2-hour post-load glucose levels between 7.8 and 11.0 mmol/l). The outcome was persistent versus normalized IGT, based on repeated oral glucose tolerance test after a median of 46 days. The discriminative ability of the original model was assessed with the area under the ROC curve (AUC). The updated model was internally validated with bootstrap resampling and cross-validated in the development population of the original model. RESULTS One-hundred eighteen of 239 (49%) patients had persistent IGT. The original model, with the predictors age, current smoking, statin use, triglyceride, hypertension, history of cardiovascular diseases, body mass index (BMI), fasting plasma glucose performed poorly (AUC .60). The newly developed model included only BMI, hypertension, statin use, atrial fibrillation, 2-hour post-load glucose levels, HbA1c, large artery atherosclerosis, and predicted persistent IGT more accurately (internally validated AUC 0.66, externally validated AUC .71). CONCLUSIONS This prediction model with simple clinical variables can be used to predict persistent IGT in patients with IGT directly after minor stroke or TIA, and may be useful to optimize secondary prevention by early identification of patients with disturbed glucose metabolism.

Abstract
AIMS Investigate if abnormal glucose tolerance (AGT) affects post-myocardial infarction (MI) prognosis in patients with hospital-related hyperglycaemia (HRH) but without known diabetes mellitus (KDM). METHODS Post-MI survivors without KDM underwent pre-discharge oral glucose tolerance test. Cardiovascular death and non-fatal re-infarction (MACE) were recorded. We compare the ability of admission (APG), fasting (FPG) and 2 h post-load (2 h-PG) plasma glucose to predict MACE in patients with (HRH) and without HRH (NoHRH). RESULTS 50.2% and 73% of NoHRH and HRH had AGT respectively. MACE occurred in 19.5% and 18.1% in HRH and NoHRH groups. MACE-free survival was lower in patient with AGT in both groups (NoHRH: HR 1.82, 95% CI 1.19-2.78, p = 0.005; HRH: HR 2.48, 95% CI 1.24-4.96, p = 0.010). AGT predicted MACE-free survival (NoHRH: HR 1.60, 95% CI 1.02-2.51, p = 0.042; HRH: HR 3.09, 95% CI 1.07-8.94, p = 0.037). 2 h-PG, but not FPG or APG, independently predicted MACE free survival (NoHRH: HR 1.17, 95% CI 1.07-1.27, p ≤0.001 and HRH: HR 1.18, 95% CI 1.03-1.37, p = 0.020). Addition of AGT and 2 h-PG, not FPG or APG, improved net reclassification of events in both groups. CONCLUSION Post-MI prognosis is worse with AGT irrespective of presence of HRH. 2 h-PG, predicts prognosis in HRH and NoHRH groups.

Abstract
Objective. Patients with diabetes have higher mortality rate than patients without diabetes after ST-segment elevated myocardial infarction (STEMI). Prognosis of patients with new onset diabetes (NOD) after STEMI remains unclear. The aim of this study was to evaluate the prognosis of patients with NOD compared to that of patients without NOD after STEMI. Design. This study was a retrospective observational study. We enrolled 901 STEMI patients. Patients were divided into diabetic and non-diabetic groups at index admission. Non-diabetic group was divided into NOD and non-NOD groups. Kaplan-Meier analysis and Cox's proportional hazard regression models were used to compare major adverse cardiac events (MACE) free survival rate and hazard ratio for MACE between NOD and non-NOD groups. Results. Mean follow-up period was 59 ± 28 months. Diabetes group had higher MACE than non-diabetes group (p = .038). However, MACE was not different between NOD and non-NOD groups (p = 1.000). After 1:2 propensity score matching, incidence of MACE was not different between the two groups. In Kaplan-Meier survival curves, MACE-free survival rates were not statistically different between NOD and non-NOD groups either (p = .244). Adjusted hazard ratios of NOD for MACE, all-cause of death, recurrent myocardial infarction, and target vessel revascularization were 0.697 (95% confidence interval [CI]: 0.362-1.345, p = .282), 0.625 (95% CI: 0.179-2.183, p = .461), 0.794 (95% CI: 0.223-2.835, p = .723), and 0.506 (95% CI: 0.196-1.303, p = .158), respectively. Conclusion. This retrospective observational study with a limited statistical power did not show a different prognosis in patients with and without NOD.

Abstract
BACKGROUND Effect of pre-diabetes mellitus on post-myocardial infarction prognosis is unclear. METHODS Retrospective cohort analysis of 1056 myocardial infarction survivors with fasting plasma glucose and 2-h post-load plasma glucose measured. Major adverse cardiovascular events included death, non-fatal reinfarction and ischaemic stroke. Cox proportional hazard regression identified predictors of event-free survival. Continuous net reclassification improvement and integrated discrimination improvement determined the added predictive value of glycaemic indices. RESULTS Major adverse cardiovascular events occurred in 25.1% and 16.4% patients with and without pre-diabetes mellitus (hazard ratio with pre-diabetes mellitus: 1.56; 95% confidence interval: 1.17-2.08; p = 0.003) in the whole cohort and in 24.1% and 17.2% patients (hazard ratio with pre-diabetes mellitus, 1.43; 95% confidence interval: 1.03-1.98; p = 0.033) in the matched cohort, respectively. Pre-diabetes mellitus predicted major adverse cardiovascular events-free survival in whole (hazard ratio: 1.39; 95% confidence interval: 1.03-1.89; p = 0.033) and matched cohorts (hazard ratio: 1.42; 95% confidence interval: 1.01-1.99; p = 0.043). The 2-h post-load plasma glucose, but not fasting plasma glucose, predicted major adverse cardiovascular events-free survival in the whole (hazard ratio: 1.16; 95% confidence interval: 1.07-1.26; p < 0.0001) and matched cohorts (hazard ratio: 1.20; 95% confidence interval: 1.09-1.31; p < 0.0001). Adding 2-h post-load plasma glucose to models containing fasting plasma glucose, significantly improved net reclassification improvement and integrated discrimination improvement for both cohorts, but not vice versa. CONCLUSION Pre-diabetes mellitus predicts major adverse cardiovascular events after myocardial infarction. The 2-h post-load plasma glucose predicts prognosis better than fasting plasma glucose in these patients.

Abstract
BACKGROUND Dysglycemia is a well-established risk factor of coronary artery disease. Less is known of the prognostic effect of dysglycemia in acute coronary syndromes (ACSs). The aim of this study was to evaluate the long-term outcome of patients with ACSs according to glucometabolic categories. METHODS Patients with ACSs were consecutively included in the study. Among those with no previous history of type 2 diabetes (T2DM) glucose metabolism was evaluated with fasting glucose in plasma, glycated hemoglobin and a standard 2-h oral glucose tolerance test. Patients were classified having normal glucose metabolism, prediabetes, newly detected T2DM (nT2DM) and previously known T2DM (kT2DM). The clinical outcome parameters were death or myocardial infarction and other major adverse cardiac events (MACEs). RESULTS A total of 372 ACS patients (male 75.8%, 65.1 years (SD: 11.8)) constituted the study population. The proportion diagnosed with normal glucose metabolism, prediabetes, nT2DM and kT2DM was 20.7%, 46.5%, 6.2% and 26.6%, respectively. The mean follow-up period was 2.9 years. Patients with prediabetes, nT2DM and kT2DM had a hazard ratio of 5.8 (95% confidence interval (CI) 0.8-44.6), 10.9 (95% CI 1.2-98.3) and 14.9 (95% CI 2.0-113.7), respectively, for death/myocardial infarction and 1.4 (95% CI 0.6-3.1), 2.9 (95% CI 1.1-8.0) and 3.3 (95% CI 1.5-7.6), respectively, for a composite of MACEs. CONCLUSION Patients with ACS and nT2DM or kT2DM were at increased risk of death/myocardial infarction and MACE compared with patients with normal glucose metabolism after approximately three years of follow-up.

Abstract
BACKGROUND Point-of-care equipment for measuring glucose saves time and costs for both patients and professionals and minimizes preanalytic errors when screening for or managing dysglycemia, that is, impaired glucose tolerance and type 2 diabetes. The accuracy of such devices has, however, been questioned compared with analyses at an accredited hospital laboratory. OBJECTIVE To investigate the agreement between glucose measurements made by the point-of-care HemoCue® Glucose 201 RT System (HemoCue, Ängelholm, Sweden) and local hospital laboratories. MATERIAL Patients with established coronary artery disease (CAD) recruited in Sweden and the United Kingdom within the auspices of the European Action on Secondary and primary Prevention by Intervention to Reduce Events (EUROASPIRE) V survey (n = 87; 18-80 years) with or without previously known dysglycemia were investigated. Plasma glucose values collected in the fasting state (n = 85) and 60 (n = 57) and 120 (n = 72) min after a glucose load were analyzed both using HemoCue monitors and local hospital laboratories. The two measurement techniques were compared using a bias plot according to Bland-Altman, the surveillance error grid, and Spearman correlation test. RESULTS The bias plot method showed small differences between the HemoCue and local hospital laboratory methods, the HemoCue and central hospital laboratory, and the local hospital laboratories and the central hospital laboratory. In the surveillance error grid, 98.6% of the values were in the deep green zone, indicating no risk and the remaining values (1.4%) were within the light green zone, indicating "slight lower risk." CONCLUSION The HemoCue point-of-care system is accurate for dysglycemia screening in patients with CAD.

Abstract
AIMS We evaluate prevalence of new abnormal glucose tolerance (AGT) in post-MI survivors without known diabetes (DM) if guidelines are followed and compare the ability of admission (APG), fasting (FPG) and 2-h post-load plasma glucose (2h-PG) to predict prognosis. METHODS A total of 674 patients were followed up for 4 years for incidence of major adverse cardiovascular events (MACE) of cardiovascular death, non-fatal re-infarction or non-haemorrhagic stroke. Ability of models including APG, FPG and 2h-PG to predict MACE was compared. RESULTS Of the total, 93-96% of impaired glucose tolerance and 64-75% of DM would be missed with current guidelines. MACE was higher in the upper quartiles of 2h-PG. When 2h-PG and FPG were included simultaneously in models, only 2h-PG predicted MACE (HR 1.12, CI 1.04-1.20, p = 0.0012), all cause mortality (HR 1.17, CI 1.05-1.30, p = 0.0039), cardiovascular mortality (HR 1.17, CI 1.02-1.33, p = 0.0205) and non-fatal MI (HR 1.10, CI 1.01-1.20, p = 0.0291). Adding 2h-PG significantly improved ability of models including FPG (χ2 = 16.01, df = 1, p = 0.0001) or FPG and APG (χ2 = 17.36, df = 1, p = 0.000) to predict MACE. Model including 2h-PG only had the lowest Akaike's information criteria and highest Akaike weights suggesting that this was the best in predicting events. Adding 2h-PG to models including FPG or APG with other co-variates yielded continuous net reclassification improvement (NRI) of 0.22 (p = 0.026) and 0.27 (p = 0.005) and categorical NRI of 0.09 (p = 0.032) and 0.12 (p = 0.014), respectively. Adding 2 h-PG to models including only FPG, only APG and both yielded integrated discrimination improvement of 0.012 (p = 0.015), 0.022 (p = 0.001) and 0.013 (p = 0.014), respectively. CONCLUSIONS AGT is under-diagnosed on current guidelines. 2h-PG is a better predictor of prognosis compared to APG and FPG.

Abstract
The purpose of this study was to investigate the prevalence of abnormal glucose regulation (AGR) in patients with established coronary artery disease (CAD), and the association of AGR and acute coronary events in Chinese patients.A total of 3441 hospitalized patients with established diagnosis of CAD were recruited from 41 centers in 25 cities of China. Oral glucose tolerance test (OGTT) was performed in 2112 patients without known diabetes. Acute coronary events were recorded for the patients.AGR was detected in 1880 (89%) patients in the OGTT cohort, with 1265 (59.9%) diagnosed with impaired glucose tolerance, 363 (17.2%) diagnosed with diabetes, and 30 (1.4%) diagnosed with isolated impaired fasting glucose. The overall proportion of patients diagnosed with diabetes increased from 30.7% (n = 930) at baseline to 42.6% (n = 1298) following the OGTT analysis. In total 85% (n = 3047) patients in the study was diagnosed with AGR. Multivariate analysis showed that AGR was independently associated with acute coronary events, after adjusting for the traditional risk factors including age, smoking, hypertension, and hyperlipidemia.The prevalence of AGR is increasing in Chinese patients with CAD, as compared with previous report. AGR was independently associated with acute coronary events. Prospective studies are warranted to evaluate the benefit of intervening prediabetes in adult patients with CAD.

Abstract
OBJECTIVE Three tests are recommended for identifying dysglycemia: fasting glucose (FPG), 2-h postload glucose (2h-PG) from an oral glucose tolerance test (OGTT), and glycated hemoglobin A1c (HbA1c). This study explored the prognostic value of these screening tests in patients with coronary artery disease (CAD). RESEARCH DESIGN AND METHODS FPG, 2h-PG, and HbA1c were used to screen 4,004 CAD patients without a history of diabetes (age 18-80 years) for dysglycemia. The prognostic value of these tests was studied after 2 years of follow-up. The primary end point included cardiovascular mortality, nonfatal myocardial infarction, stroke, or hospitalization for heart failure and a secondary end point of incident diabetes. RESULTS Complete information including all three glycemic parameters was available in 3,775 patients (94.3%), of whom 246 (6.5%) experienced the primary end point. Neither FPG nor HbA1c predicted the primary outcome, whereas the 2h-PG, dichotomized as <7.8 vs. ≥7.8 mmol/L, was a significant predictor (hazard ratio 1.38, 95% CI 1.07-1.78; P = 0.01). During follow-up, diabetes developed in 78 of the 2,609 patients (3.0%) without diabetes at baseline. An FPG between 6.1 and 6.9 mmol/L did not predict incident diabetes, whereas HbA1c 5.7-6.5% and 2h-PG 7.8-11.0 mmol/L were both significant independent predictors. CONCLUSIONS The 2h-PG, in contrast to FPG and HbA1c, provides significant prognostic information regarding cardiovascular events in patients with CAD. Furthermore, elevated 2h-PG and HbA1c are significant prognostic indicators of an increased risk of incident diabetes.

Abstract
Background Type 2 diabetes and prediabetes are established risk factors for atherosclerosis. The aim of this study was to evaluate the atherosclerotic plaque burden in the carotid arteries of patients with acute coronary syndrome according to their glycemic status. Methods Patients with acute coronary syndrome and no previous history of type 2 diabetes were consecutively included in the study. Glucose metabolism was evaluated with fasting glucose in plasma, HbA1c and a standard two-hour oral glucose tolerance test. Atherosclerotic plaque in the carotid arteries was evaluated with a standardized ultrasound examination where total plaque area was measured and patients classified as having no plaque or a significant plaque formation. Results A total of 245 acute coronary syndrome patients (male 78%, 64 years (SD: 10.9)) were included. The proportion diagnosed with normal glucose metabolism, prediabetes and type 2 diabetes was 28.6%, 64.1% and 7.3%, respectively. A significant atherosclerotic plaque was found in 48.5%, 66.9% and 72.2% of patients with normal glucose metabolism, prediabetes and type 2 diabetes, respectively. An incremental increase in total plaque area was found from normal glucose metabolism to prediabetes (25.5%) and from normal glucose metabolism to type 2 diabetes (35.9%) (p = 0.04). When adjusted for conventional cardiovascular risk factors the OR of having significant atherosclerotic plaque in the carotid arteries was 2.17 (95% CI 1.15–4.15) for patients with newly diagnosed dysglycemia compared to patients with normal glucose metabolism. When additionally adjusted for the 2-hour plasma glucose after glucose loading (2hPG) the OR attenuated to 1.77 (95% CI 0.83–3.84). Conclusion Newly detected dysglycemia is an independent predictor of significant atherosclerotic plaque in the carotid arteries with oral glucose tolerance test as a major determinant of carotid plaque burden in this group of individuals with acute coronary syndrome.

Abstract
OBJECTIVES Recent advances in catheter-based intervention in patients with symptomatic peripheral arterial disease (PAD) have halved mortality. Mortality of PAD patients still remains high compared to other clinical forms of atherosclerosis. Intensified patient care might increase adherence to medical management and benefit the survival of PAD patients. METHODS Two patient cohorts were compared in a longitudinal prospective follow-up study. 370 PAD patients were included in the intensified center-based vascular medicine group (VMC group) and 332 PAD patients were treated by their usual primary care physician (PCP group). Survival in both groups was compared by Kaplan-Meier and Cox-regression analyses after 5 years. RESULTS Survival of patients in the VMC group was 90.8% compared to 66% in the PCP group. Thus, survival was improved by 24.9% by center-based care (absolute risk CI: 19-30.7%; 38% relative risk). PCP treatment increased all-cause mortality by a hazard ratio of 3.7 (95% CI: 2.5-5.5; p < .001). Mortality in the VMC group was significantly associated with the non-modifiable risk factors age, C-reactive protein, and nephropathy in multivariable analyses. CONCLUSION These data imply that multi-morbid elderly PAD patients still benefit by intensified specialist care compared to the usual primary care setting. KEY MESSAGES Center-based patient care improves survival in patients with peripheral arterial disease; mortality was reduced from 82 to 21 events per 1000 patient-years (rate ratio 0.26). Mortality was related to age (HR 1.46), CRP (HR 1.36), and nephropathy (HR 2.7). A multifactorial approach combining adequate drug prescription, accomplishment of agreed goals and repetitive training to initiate, implement, and persist treatment adaptations was applied.

Abstract
Objectives: Abnormal glucose tolerance in patients with acute myocardial infarction (AMI) is associated with greater mortality and adverse cardiovascular effects. As statins possess a range of beneficial pleiotropic effects on the cardiovascular system, we sought to assess the cardioprotective effects of statins on left ventricular function in patients with AMI in relation to glycometabolic state. Methods: In a prospective, randomized trial, 140 patients with AMI were randomized to intensive statin therapy receiving statin loading with 80 mg of rosuvastatin followed by 40 mg daily or standard statin therapy. Patients were assessed with an oral glucose tolerance test and their left ventricular (LV) function was assessed with speckle-tracking echocardiography measuring regional longitudinal systolic strain (RLSS) in the infarct area. Results: Overall RLSS in the infarct area improved by a mean (±SD) of -4.22% (±5.19) in the intensive-care group and -2.48% (±4.01) in the usual-care group after 1 month (p = 0.047). In patients with abnormal glucose tolerance, RLSS improved by -5.01% (±5.28) in the intensive-care group and -2.15% (±4.22) in the usual-care group (p = 0.01). Conclusions: Early high-dose statin treatment improved RLSS in the infarct area in patients with AMI, and a trend of greater improvement was seen in patients with abnormal glucose tolerance.

Abstract
Background Diabetes and pre-diabetes are prevalent in acute coronary syndrome (ACS) and relate to adverse outcomes. This study used HbA1c to screen for degrees of glucose intolerance amongst patients without known diabetes presenting with ACS. Methods Over a 1-year period (June 2014–2015) consecutive patients admitted to a single centre cardiology unit with an initial diagnosis of ACS without prior diabetes diagnosis were electronically referred to our diabetes team. Patients were screened for the presence of diabetes by use of an initial HbA1c blood test on day 2 or 3 post admission. If abnormal (≥42 mmol/mol; ≥6.0%), patients were invited for a repeat HbA1c at 2 weeks, and if an intermediate result (42–47 mmol/mol; 6.0–6.4%), for an oral glucose tolerance test (OGTT) at 3 months. Patients were diagnosed with Type 2 diabetes if the repeat HbA1c result was high (≥48 mmol/mol; ≥6.5%) or the OGTT at 3 months confirmed the diagnosis. Other data collected included baseline demographics, risk factors and any history of cardiovascular disease. All patients with ACS were stratified according to the diagnosis and subsequent management. Results We screened 399 patients in total. The mean age was 65 ± 14 years, 268 (67%) were men, 290 (73%) were Caucasian, 95 (24%) were South Asian and 14 (4%) were Afro-Caribbean ethnicity. Of all patients, 57 (14.3%) were diagnosed as pre-diabetes and 43 (10.8%) newly diagnosed diabetes. During the study 28 (7%) patients could not be classified; 6 (1.5%) patients died during the study and 22 (5.5%) patients were missing either initial or repeat HbA1c and were subsequently lost to follow up. Of the baseline variables assessed, there were significantly more patients of South Asian ethnicity in the diabetes group compared to the normal group (42 vs 20%; p = 0.003). There was no difference in detection rates in patients with more severe ACS requiring percutaneous or cardiac surgical intervention. Conclusions The use of a simple HbA1c screening method in clinical practice can detect new onset diabetes in approximately 1 in 10 high-risk post ACS patients.

Abstract
OBJECTIVE To characterize copeptin levels and to explore its prognostic importance in patients with acute myocardial infarction with newly detected glucose abnormalities. METHODS Copeptin was measured in 166 patients with acute myocardial infarction without known diabetes and in 168 age- and gender-matched controls. Participants were classified as having normal glucose tolerance or abnormal glucose tolerance (impaired glucose tolerance + type 2 diabetes mellitus) by oral glucose tolerance test. Study participants were followed over a decade for major cardiovascular event (acute myocardial infarction/stroke/congestive heart failure/cardiovascular death), cardiovascular and total death. RESULTS Median copeptin level was higher in patients (10.5 pmol/L) than controls (5.9 pmol/L; p < 0.01). Patients with abnormal glucose tolerance had higher copeptin (12.2 pmol/L) than those with normal glucose tolerance (7.9 pmol/L; p < 0.01) but levels of copeptin did not differ in controls with abnormal glucose tolerance or normal glucose tolerance. Copeptin predicted major cardiovascular events [ n = 64; hazard ratio = 1.15 (1.01-1.32; p = 0.04)], cardiovascular mortality [ n = 29; hazard ratio = 1.24 (1.06-1.46; p = 0.01)] and total death [ n = 51; hazard ratio = 1.21 (1.05-1.40; p = 0.01)] in unadjusted Cox regression analyses in the patient cohort. In controls, copeptin predicted major cardiovascular events [ n = 26; hazard ratio = 1.17 (1.01-1.36; p = 0.03)]. CONCLUSION Copeptin levels are highest among acute myocardial infarction patients with glucose disturbances and predict an adverse prognosis in unadjusted analyses. These findings imply that raised copeptin reflects stress rather than acting as a pathogenic factor for glucose abnormalities.

Abstract
OBJECTIVES Newly diagnosed disturbed glucose metabolism is highly prevalent in patients with stroke. Limited data are available on their prognostic value on outcome after stroke. We aimed to assess the association of glucose in the prediabetic and diabetic range with unfavourable short-term outcome after stroke. MATERIALS AND METHODS We included 839 consecutive patients with ischemic stroke and 168 patients with intracerebral haemorrhage. In all nondiabetic patients, fasting glucose levels were determined on day 2-4. Prediabetic range was defined as fasting glucose of 5.6-6.9 mmol/L, diabetic range as ≥7.0 mmol/L, pre-existent diabetes as the use of anti-diabetic medication prior to admission. Outcome measures were poor functional outcome or death defined as modified Rankin Scale (mRS) score >2 and discharge not to home. The association of prediabetic range, diabetic range and pre-existent diabetes (versus normal glucose) with unfavourable outcome was expressed as odds ratios, estimated with multiple logistic regression, with adjustment for prognostic factors. RESULTS Compared with normal glucose, prediabetic range (aOR 1.8; 95%CI 1.1-2.8), diabetic range (aOR 2.5; 95%CI 1.3-4.9) and pre-existent diabetes (aOR 2.6; 95%CI 1.6-4.0) were associated with poor functional outcome or death. Patients in the prediabetic range (aOR 0.6; 95%CI 0.4-0.9), diabetic range (aOR 0.4; 95%CI 0.2-0.9) and pre-existent diabetes (aOR 0.6; 95%CI 0.4-0.9) were more likely not to be discharged to home. CONCLUSIONS Patients with glucose in the prediabetic and diabetic range have an increased risk of unfavourable short-term outcome after stroke. These findings illustrate the potential impact of early detection and treatment of these patients.

Abstract
Objectives To prevent the onset of lifestyle-related diseases associated with metabolic syndrome (MetS) in Japan, research into the development of a useful screening method is strongly desired. We developed a new screening questionnaire (JAMRISC) utilizing a logistic regression model and evaluated its ability to predict the development of MetS, type 2 diabetes and other lifestyle-related diseases in Japanese populace. Methods JAMRISC questionnaire was sent to 1,850 individuals in Rumoi, a small city in Hokkaido. We received a total of 1,054 valid responses. To maximize the target individuals accurately diagnosed with MetS, logistic regression analysis was used to generate a unique metabolic syndrome score calculation formula as taking into consideration the clinical relevance of each question item as individual coefficients. Results The results of our comparative research utilizing both JAMRISC and Finnish Diabetes Risk Score (FINDRISC) questionnaires revealed the usefulness of JAMRISC for its ability to detect risks for MetS, pre-MetS, diabetes, and pre-diabetes. Study of disease risk detection via JAMRISC questionnaire targeting the 4283 residents of Rumoi indicated a high detection rate for pre-MetS (98.8 %), MetS (94.2 %), pre-diabetes (85.1 %) and type 2 diabetes (94.9 %). In addition, JAMRISC was useful not only as a MetS risk score test, but also as a screening tool for diagnosing insulin resistance. Conclusions JAMRISC questionnaire is a useful instrument for the detection of early risk of not only MetS and type 2 diabetes but also insulin resistance.

Abstract
BACKGROUND It is not well-known to what extent evidence-based medications, such as beta-blockers, hypolipidemic medications, and angiotensin-converting enzyme inhibitors, are prescribed after an attack of acute coronary syndrome in the general healthcare setting and what is the compliance of patients with these prescriptions. DESIGN We conducted a countrywide record linkage study. METHODS We used record linkage of the National Hospital Discharge Register, Causes of Death Register, and Social Insurance Institution's drug reimbursement records to identify drug purchases of patients aged 35-74 years hospitalized for the first nonfatal acute coronary syndrome in Finland during 1995-2003 (n=53 353). RESULTS In 2003 about 28 and 15% of the patients did not receive hypolipidemic medications or beta-blockers, respectively, after their acute coronary syndrome and a further 6 and 10% discontinued the use about 3 months later. Patients aged 65-74 years were less likely to receive hypolipidemic medications [odds ratio (OR) 0.55; 95% confidence interval (CI), 0.53-0.58] and beta-blockers (OR 0.77; 95% CI, 0.74-0.81) than younger patients. Diabetic patients received less hypolipidemic medications (OR 0.82; 95% CI, 0.78-0.86) and were more likely to discontinue the medication (OR 1.15; 95% CI, 1.05-1.26) than nondiabetic patients. In proportional hazards regression analyses the regular use of hypolipidemic medication or beta-blockers was associated with lower risk of cardiovascular death: adjusted hazard ratios 0.47 (95% CI, 0.41-0.53) and 0.54 (95% CI, 0.49-0.60), respectively. CONCLUSIONS Our study showed that the evidence-based use of medications after acute coronary syndrome was suboptimal in Finland, particularly in elderly and diabetic patients. Consistent use of these medications, however, was associated with a better prognosis.

Abstract
AIM Diabetic patients with coronary artery disease have a high incidence of cardiovascular events, which was associated with increased coronary plaque volume. Low-density lipoprotein cholesterol (LDL-C) and blood pressure (BP) play pivotal roles in the progression of coronary plaque. Several trials have shown that intervention for a single risk factor reduced the development of coronary plaque progression. However, it remained uncertain whether total risk management for LDL-C, BP, and glycosylated Hb (HbA1c) has a beneficial effect on coronary plaque volume in diabetic patients. METHODS This study was a sub-study of the JAPAN-ACS that was a prospective, randomized, open-label trial that evaluated the impact of intensive lipid-lowering therapy on coronary plaque volume in patients with acute coronary syndrome (ACS). Among a total of 252 patients, 73 diabetic patients were analyzed. We examined the impact of total risk management (LDL-C <80 mg/dL, systolic BP <130 mmHg, and HbA1c <6.5%) on changes in coronary plaque volume. The patients were divided into four groups according to the number of risk factors that achieved the target value. RESULTS Baseline characteristics were similar among the groups. The degree of coronary plaque regression was greater in patients who achieved total risk management. The number of risk factors that achieved the target level was associated with the extent of the coronary plaque volume reduction in a dose-dependent manner. CONCLUSION Total risk management that focused on LDL-C, BP, and HbA1c had a beneficial impact on the coronary plaque regression in diabetic patients with ACS.

Abstract
BACKGROUNDS/OBJECTIVES We aimed at assessing the impact of increased HbA1c (≥6.5%) on 1-year mortality in consecutive patients with ST Elevation Myocardial Infarction (STEMI) submitted to primary percutaneous coronary intervention (PCI). METHODS The study population comprises 1205 STEMI patients treated with primary PCI and consecutively admitted to our Center from 1 January 2004 to 31 December 2011. RESULTS Two hundred and seventy-six patients with previously diagnosed diabetes (276/1205, 22.9%, Group A), 78 patients without previously known diabetes and HbA1c at least 6.5% (78/1205, 6.5%, Group B) and 851 patients without previously known diabetes and HbA1c less than 6.5% (851/1205, 70.1%, Group C).At Cox regression analysis, HbA1c at least 6.5% was not related to 1-year postdischarge mortality in patients with previously diagnosed diabetes nor in those without previously known diabetes.Kaplan-Meier survival curve analysis showed that patients in Group A exhibited the lowest survival rate, while patients in Group B (i.e. patients without previously known diabetes and with HbA1c ≥6.5%) showed a significant reduction in their survival rate since 6 months after discharge. CONCLUSION In a large series of STEMI patients submitted to primary PCI, HbA1c levels were not related with outcomes at multivariable analysis.

Abstract
BACKGROUND Alterations in glucose metabolism have been reported as risk and poor prognostic factors for acute myocardial infarction (AMI); however in Latin-American population this information is limited. Thus, an evaluation was performed on the association between glycaemic status and short- and long-term outcomes in patients with a first AMI. METHODS A multicentre, prospective, observational, cohort study was conducted in 8 hospitals from Colombia and Ecuador. RESULTS A total of 439 patients with confirmed AMI were included, of which 305 (69.5%) had prediabetes or type2 diabetes mellitus (DM2). Compared with normal glycaemia group, patients with known DM2 had greater risk of prolonged hospital stay (HR: 2.60, 95%CI: 1.38-4.92, P=.003), Killip class iii/iv (HR: 9.46, 95%CI: 2.20-40.62, P=.002), and in-hospital heart failure (HR: 10.76, 95%CI: 3.37-34.31, P<.001). Patients with prediabetes, new DM2, and known DM2 showed higher rates of major adverse cardiovascular events after 3years follow-up. CONCLUSION Glucose metabolism abnormalities have an important significance in the short- and long-term prognosis in Latin-American patients that survive a first AMI.

Abstract
Objective To investigate the prognostic effect of newly diagnosed diabetes mellitus (NDM) and impaired glucose tolerance (IGT) post myocardial infarction (MI). Research Design and Methods Retrospective cohort study of 768 patients without preexisting diabetes mellitus post-MI at one centre in Yorkshire between November 2005 and October 2008. Patients were categorised as normal glucose tolerance (NGT n = 337), IGT (n = 279) and NDM (n = 152) on pre- discharge oral glucose tolerance test (OGTT). Primary end-point was the first occurrence of major adverse cardiovascular events (MACE) including cardiovascular death, non-fatal MI, severe heart failure (HF) or non-haemorrhagic stroke. Secondary end-points were all cause mortality and individual components of MACE. Results Prevalence of NGT, impaired fasting glucose (IFG), IGT and NDM changed from 90%, 6%, 0% and 4% on fasting plasma glucose (FPG) to 43%, 1%, 36% and 20% respectively after OGTT. 102 deaths from all causes (79 as first events of which 46 were cardiovascular), 95 non fatal MI, 18 HF and 9 non haemorrhagic strokes occurred during 47.2 ± 9.4 months follow up. Event free survival was lower in IGT and NDM groups. IGT (HR 1.54, 95% CI: 1.06–2.24, p = 0.024) and NDM (HR 2.15, 95% CI: 1.42–3.24, p = 0.003) independently predicted MACE free survival. IGT and NDM also independently predicted incidence of MACE. NDM but not IGT increased the risk of secondary end-points. Conclusion Presence of IGT and NDM in patients presenting post-MI, identified using OGTT, is associated with increased incidence of MACE and is associated with adverse outcomes despite adequate secondary prevention.

Abstract
OBJECTIVE To evaluate the prevalence and persistence of postoperative glycemic abnormalities in patients without a history of diabetes, undergoing cardiac surgery (CS). METHODS Ninety-two patients without diabetes with planned elective CS procedures at a tertiary institution were evaluated preoperatively and 3 months postoperatively for measures of glucose control including hemoglobin A1c, fasting plasma glucose, 2-h post oral glucose load, and insulin levels. Data from the hospital course were recorded. RESULTS Valid data were available from 61 participants at 3 months; 59% had prediabetes and 10% had diabetes preoperatively by one or more diagnostic criteria and continued to be dysglycemic at 3 months. Preoperative A1C was an independent predictor of postoperative hyperglycemia (p = 0.02). Insulin resistance and BMI rather than glycemic abnormalities before surgery were associated with a longer duration of the postoperative insulin infusion (p = 0.004, p = 0.048). CONCLUSION Seventy percent of CS patients without known diabetes met criteria for diabetes or prediabetes preoperatively, and these abnormalities persisted after surgery.

Abstract
Is coronary revascularization required in a patient with chronic stable coronary artery disease or can optimized medical therapy (OMT) alone be a sufficient alternative? This question has been controversially discussed for non-diabetics as well as for diabetics since the COURAGE and BARI 2D trials. According to our present knowledge, a patient will benefit from coronary revascularization only when either a non-invasive test method, such as single photon emission computed tomography (SPECT) or positron emission tomography (PET) myocardial scintigraphy, stress echocardiography or stress nuclear magnetic resonance imaging, can detect relevant, objective evidence of ischemia >10% of the left ventricular myocardium or when a pathological fractional flow reserve (FFR) <0.80 can be measured in an invasive procedure for an angiographically detectable coronary stenosis. If similar relevant ischemia can be non-invasively or invasively objectified in a patient with chronic stable multivessel coronary artery disease, the often controversially discussed question arises particularly in diabetics whether a percutaneous coronary intervention (PCI) with implantation of drug-eluting stents or coronary artery bypass surgery should be favored. The FREEDOM study (Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multivessel Disease), published in November 2012, was the first prospective randomized study to examine this issue in diabetic patients with multivessel coronary artery disease. Despite a higher rate of stroke in the surgical cohort, after an average follow-up time of 3.8 years a significant prognostic advantage in favor of bypass surgery was detected for a combined primary endpoint of all-cause mortality, nonfatal myocardial infarction and nonfatal stroke. Thus, in the new ESC guidelines on diabetes, pre-diabetes and cardiovascular diseases developed with the EASD of the European Society of Cardiology and published in 2013, coronary bypass surgery has a class I, level of evidence A recommendation for patients with diabetes mellitus, chronic stable multivessel coronary disease and a synergy between PCI with taxus and cardiac surgery (SYNTAX) score >22. The decision for or against a PCI/stent implantation or coronary bypass surgery in a diabetic patient with chronic stable multivessel coronary artery disease should therefore be made with the patient only after a detailed informed consent discussion and comprehensive explanation of both treatment options. In controversial cases, particularly with an equivocal SYNTAX score around 22, relevant comorbidities or anticipated method-specific complications, a one-stage ad hoc intervention during the diagnostic coronary angiography should be rejected in favor of a two-stage procedure with prior discussion of both treatment options in the heart team comprising noninvasive cardiologists, interventional cardiologists and cardiac surgeons.

Abstract
OBJECTIVE To investigate long-term prognostic importance of newly discovered glucose disturbances in patients with acute myocardial infarction (AMI). METHODS During 1998-2001, consecutive patients with AMI (n = 167) and healthy controls (n = 184) with no previously known diabetes were investigated with an oral glucose tolerance test (OGTT). Patients and controls were separately followed up for cardiovascular events (first of cardiovascular mortality/AMI/stroke/heart failure) during a decade. RESULTS In all, 68% of the patients and 35% of the controls had newly detected abnormal glucose tolerance (AGT). Cardiovascular event (n = 72, p = 0.0019) and cardiovascular mortality (n = 31, p = 0.031) were more frequent in patients with newly detected AGT. Regarding patients, a Cox proportional-hazard regression analysis identified AGT (hazard ratio (HR): 2.30; 95% confidence interval (CI): 1.24-4.25; p = 0.008) and previous AMI (HR: 2.39; CI: 1.31-4.35; p = 0.004) as prognostically important. CONCLUSION An OGTT at discharge after AMI disclosed a high proportion of patients with previously unknown AGT which had a significant and independent association with long-term prognosis.

Abstract
AIM: To evaluate the impact on glucose variability (GLUCV) of an nurse-implemented insulin infusion protocol when compared with a conventional insulin treatment during the day-to-day clinical activity.
METHODS: We enrolled 44 type 2 diabetic patients (n = 32 males; n = 12 females) with acute coronary syndrome (ACS) and randomy assigned to standard a subcutaneous insulin treatment (n = 23) or a nurse-implemented continuous intravenous insulin infusion protocol (n = 21). We utilized some parameters of GLUCV representing well-known surrogate markers of prognosis, i.e., glucose standard deviation (SD), the mean daily δ glucose (mean of daily difference between maximum and minimum glucose), and the coefficient of variation (CV) of glucose, expressed as percent glucose (SD)/glucose (mean).
RESULTS: At the admission, first fasting blood glucose, pharmacological treatments (insulin and/or anti-diabetic drugs) prior to entering the study and basal glycated hemoglobin (HbA1c) were observed in the two groups treated with subcutaneous or intravenous insulin infusion, respectively. When compared with patients submitted to standard therapy, insulin-infused patients showed both increased first 24-h (median 6.9 mmol/L vs 5.7 mmol/L P < 0.045) and overall hospitalization δ glucose (median 10.9 mmol/L vs 9.3 mmol/L, P < 0.028), with a tendency to a significant increase in first 24-h glycaemic CV (23.1% vs 19.6%, P < 0.053). Severe hypoglycaemia was rare (14.3%), and it was observed only in 3 patients receiving insulin infusion therapy. HbA1c values measured during hospitalization and 3 mo after discharge did not differ in the two groups of treatment.
CONCLUSION: Our pilot data suggest that no real benefit in terms of GLUCV is observed when routinely managing blood glucose by insulin infusion therapy in type 2 diabetic ACS hospitalized patients in respect to conventional insulin treatment
