Abstract
BACKGROUND In the COMPLETE trial (Complete Versus Culprit-Only Revascularization to Treat Multivessel Disease After Early PCI for STEMI), a strategy of complete revascularization reduced the risk of major cardiovascular events compared with culprit-lesion-only percutaneous coronary intervention in patients presenting with ST-segment-elevation myocardial infarction (STEMI) and multivessel coronary artery disease. Patients with diabetes have a worse prognosis following STEMI. We evaluated the consistency of the effects of complete revascularization in patients with and without diabetes. METHODS The COMPLETE trial randomized a strategy of complete revascularization, consisting of angiography-guided percutaneous coronary intervention of all suitable nonculprit lesions, versus a strategy of culprit-lesion-only percutaneous coronary intervention (guideline-directed medical therapy alone). In prespecified analyses, treatment effects were determined in patients with and without diabetes on the first coprimary outcome of cardiovascular death or new myocardial infarction and the second coprimary outcome of cardiovascular death, new myocardial infarction, or ischemia-driven revascularization. Interaction P values were calculated to evaluate whether there was a differential treatment effect in patients with and without diabetes. RESULTS Of the 4041 patients enrolled in the COMPLETE trial, 787 patients (19.5%) had diabetes. The median HbA1c (glycated hemoglobin) was 7.7% in the diabetes group and 5.7% in the nondiabetes group. Complete revascularization consistently reduced the first coprimary outcome in patients with diabetes (hazard ratio, 0.87 [95% CI, 0.59-1.29]) and without diabetes (hazard ratio, 0.70 [95% CI, 0.55-0.90]), with no evidence of a differential treatment effect (interaction P=0.36). Similarly, for the second coprimary outcome, no differential treatment effect (interaction P=0.27) of complete revascularization was found in patients with diabetes (hazard ratio, 0.61 [95% CI, 0.43-0.87]) and without diabetes (hazard ratio, 0.48 [95% CI, 0.39-0.60]). CONCLUSIONS Among patients presenting with STEMI and multivessel disease, the benefit of complete revascularization over a culprit-lesion-only percutaneous coronary intervention strategy was consistent regardless of the presence or absence of diabetes.

Abstract
Coronary artery calcium (CAC) measures subclinical atherosclerosis and improves risk stratification. CAC characteristics-including vessel(s) involved, number of vessels, volume, and density-have been shown to differentially impact risk. We assessed how dispersion-either the number of calcified vessels or CAC phenotype (diffuse, normal, and concentrated)-impacted cause-specific mortality. The CAC Consortium is a retrospective cohort of 66,636 participants without coronary heart disease (CHD) who underwent CAC scoring. This study included patients with CAC >0 (n = 28,147). CAC area, CAC density, and CAC phenotypes (derived from the index of diffusion = 1 - [CAC in most concentrated vessel/total Agatston score]) were calculated. The associations between CAC characteristics and cause-specific mortality were assessed. The participant details included (n = 28,147): mean age 58.3 years, 25% female, 89.6% White, and 66% had 2+ calcified vessels. Diabetes, hypertension, and hyperlipidemia were predictors of multivessel involvement (p <0.001). After controlling for the overall CAC score, those with 4-vessel CAC involvement had more CAC area and less dense calcifications than those with 1-vessel. There was a graded increase in all-cause and cardiovascular disease (CVD)- and CHD-specific mortality as the number of calcified vessels increased. Among those with ≥2 vessels involved (n = 18,516), a diffuse phenotype was associated with a higher CVD-specific mortality and had a trend toward higher all-cause and CHD-specific mortality than a concentrated CAC phenotype. Diffuse CAC involvement was characterized by less dense calcification, more CAC area, multiple coronary vessel involvement, and presence of certain traditional risk factors. There is a graded increase in all-cause and CVD- and CHD-specific mortality with increasing CAC dispersion.

Abstract
BACKGROUND Diabetes mellitus (diabetes) increases the risk of severe coronary artery calcification, which increases the complexity of percutaneous coronary intervention requiring rotational atherectomy (RA) by interfering with lesion preparation, and limiting final stent expansion. OBJECTIVE Investigate 30-day and 18-month clinical outcomes in patients with and without diabetes treated with percutaneous coronary intervention requiring RA. DESIGN Medical record review SETTING: Multicenter registry in South Korea PATIENTS AND METHODS: The ROtational atherectomy in Calcified lesions in Korea (ROCK) registry was a large, retrospective, multicenter study to assess RA treatment of severe coronary artery calcification. MAIN OUTCOME MEASURES The primary endpoint was target-vessel failure including cardiac death, target-vessel myocardial infarction, and target-vessel revascularization. SAMPLE SIZE 540 patients followed for a median of 16.1 months. RESULTS Of the 540 patients, 305 had diabetes (56.5%). The diabetes group had a significantly higher frequency of multivessel disease; comorbidities such as hypertension, dyslipidemia, and chronic kidney disease; and lower ejection fraction of the left ventricle compared to the non-diabetes group (n=235). There were no significant differences in procedure success and complications observed between the two groups. Target vessel failure at 30 days between the diabetes and non-diabetes groups was not statistically significant in a multivariate Cox regression analysis (1.6% vs. 2.6%, adjusted hazard ratio [HR] 0.595, 95% confidence interval [CI] 0.154-2.300, P=.451). During an 18-month follow-up, the risk of target vessel failure was higher (12.5% vs. 8.9%) but the difference was not statistically significant (adjusted HR 1.393, 95% CI 0.782-2.482, P=.260). CONCLUSIONS Patients with diabetes have a risk of complications comparable to patients without diabetes, and 30-day and 18-month clinical outcomes are similar in severe coronary artery calcification requiring RA, despite having more comorbidities. LIMITATIONS Retrospective design. Sample size not based on power calculation. CONFLICT OF INTEREST None.

Abstract
The choice between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for myocardial revascularization in patients with left main disease (LMD) is controversial. There is general agreement that CABG is appropriate for all patients, and PCI is acceptable for those with low-to-intermediate anatomic complexity. However, there is uncertainty about the relative safety and efficacy of PCI in patients with more complex LMD and with comorbidities such as diabetes. No direct comparison trial has focused on revascularization in diabetic patients with LMD, and thus conclusions on the topic are subject to the limitations of subgroup analysis, as well as the heterogeneous exclusion criteria, and methodologies of individual trials. The available evidence suggests that among diabetics, CABG is superior in patients with LMD with SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and dardiac surgery) score greater than 33, distal bifurcation disease, or multivessel disease. PCI may be appropriate in those with less-extensive disease or those with limited life expectancy or high surgical risk.

Abstract
Abstract
There is a concern regarding the high incidence of coronary heart disease (CHD) among patients with diabetes mellitus (DM) type 2 since it is a leading cause of mortality in those patients. Exercise treadmill test (ETT) is proposed as a suitable, non-invasive method for identifying asymptomatic patients with ischemic changes, who would benefit from pharmacological treatment, thus contributing to a reduction of adverse cardiovascular events. Therefore the objective of our study was to evaluate myocardial ischemia in asymptomatic patients with DM type 2 by performing ETT. The present investigation was conducted in Health Center Pozega during the year 2018. 40 insulin-dependent, aged 33.05 ± 2.01 years, with DM type 2 were included in the study. They had nor history nor symptoms of cardiac disease. All patients underwent ETT according to Bruce protocol, while 12-lead ECG was recorded and blood pressure was monitored. All patients had negative ETT results. Also no ST segment depression, no signs of insufficiency of peripheral circulation, no changes in heart rhythm, no symptoms by the central nervous system were observed. Additionally response of heart rate and blood pressure to exercise was within physiological range. These promising findings indicate that diabetes didn’t alter myocardial integrity and function, thus suggesting that coronary reserve in examined patients was preserved.

Abstract
BACKGROUND It is known that patients with acute coronary syndromes (ACS) and diabetes mellitus (DM) are at higher risk for in-hospital adverse events. However, we hypothesized that the higher event rate is due to the patients' subgroup with renal failure (RF), a common sequel of DM. METHODS AND RESULTS We used data of the prospective ALKK-PCI registry including all consecutive percutaneous coronary interventions (PCI) for ACS of 48 hospitals between 2008 and 2013. We divided 69,651 patients in four groups according to their history of DM and RF (GFR < 60 ml/min). All-cause, in-hospital mortality of the following four groups: noDM/noRF, DM/noRF, DM/RF, RF/noDM, was: 3.5%, 6.6%, 21.9%, and 14.1% for STEMI and 1.5%, 2.1%, 7.2%, and 5.4% for NSTE-ACS. In a multivariate analysis we looked for independent mortality-predictors. Odds ratios with confidence intervals for the following variables: DM without RF, DM with RF, RF without DM were: 1.62 (1.37-1.90), 3.02 (2.43-3.76), and 2.13 (1.80-2.52) for STEMI and 1.20 (0.99-1.45), 2.72 (2.18-3.88), and 2.08 (1.69-2.56) for NSTE-ACS. We also calculated mortality in four groups (60-90, 45-60, 45-30, <30 ml/min) according to the estimated glomerular filtration rate (eGFR). Mortality rates were: 5.0%, 12.8%, 17.7%, and 31.5% for STEMI and 2.1%, 3.8%, 7.1%, and 12.0% for NSTE-ACS (p for trend <0.0001 for both). CONCLUSIONS In-hospital death after PCI in patients with ACS and DM is mainly observed in the subgroup with co-existing RF. In a multivariate analysis, DM without RF was a significant mortality-predictor in STEMI, but not in NSTE-ACS. RF, irrespective of co-existent DM, was a stronger predictor than DM alone for both ACS-types (OR > 3) and mortality increased with decreasing eGFR.

Abstract
We investigated the associations between extended clopidogrel therapy and long-term clinical outcomes in patients with diabetes mellitus (DM) after second-generation drug-eluting stent (DES) implantation. Landmark analysis was performed in 1,600 patients who received second-generation DES and were event-free at 12 months after the index procedure. The primary outcome was a composite of all-cause death or nonfatal myocardial infarction (MI) at 5 years after the index procedure. After inverse probability of treatment weighting analysis, the risk of all-cause death, or nonfatal MI was significantly lower in patients receiving clopidogrel >12 months than in those receiving clopidogrel ≤12 months in diabetic patients (13.9% vs 8.4%, hazard ratio [HR] 0.57, 95% confidence interval [CI] 0.33 to 0.99, p = 0.046). However, no significant difference was observed in all-cause death or nonfatal MI between the two groups of patients without DM (5.0% vs 8.1%, HR 1.63, 95% CI 0.90 to 2.96, p = 0.11). Extended clopidogrel therapy beyond 12 months was associated with decreased risk of all-cause death or nonfatal MI in patients with DM after second-generation DES implantation. In conclusion, our data suggest that the benefits of extended clopidogrel therapy are more prominent in diabetic patients receiving second-generation DES implantation compared with nondiabetic patients.

Abstract
Coronary artery disease in patients with diabetes mellitus (DM) is characterized by extensive atherosclerosis, longer lesions, and diffuse distal disease. Consequently, these patients have worse outcomes after coronary revascularization, regardless of the modality used. Traditionally, coronary artery bypass grafting (CABG) has been regarded as more effective than percutaneous coronary intervention (PCI) in patients with DM, likely because of more complete revascularization and protection against disease progression in the bypass segment. Revascularization with balloon angioplasty, bare-metal stents, and first-generation drug-eluting stents have all been shown to be inferior to CABG in patients with DM. Current professional society guidelines reflect these findings, strongly recommending CABG over PCI in this setting. Newer stent platforms, however, have challenged this notion. The use of thinner struts, biocompatible polymer coating, and newer antiproliferative agents have improved the rates of cardiovascular events in patients with DM revascularized percutaneously. Since the publication of current guidelines, new studies suggested acceptable outcomes in patients with DM revascularized with second-generation drug-eluting stents, even though these conclusions are drawn from small subgroup analyses or nonrandomized studies. Robust registry data suggest similar mortality with lower rates of stroke after PCI compared with surgery, at the expense of increased rates of repeat revascularization. If complete revascularization can be achieved, similar rates of myocardial infarction are also observed. Therefore, contemporary revascularization in patients with DM with multivessel coronary artery disease should involve a multidisciplinary approach, in which interventional cardiologists and cardiac surgeons involve their patients to individualize treatment choices, and balance the risks and effectiveness of each modality.

Abstract
Diabetes mellitus is associated with an increased risk of coronary heart disease (CHD) morbidity and mortality. Although it frequently coexists with other cardiovascular disease (CVD) risk factors, it confers an increased risk for CVD events on its own. Coronary atherosclerosis is generally more aggressive and widespread in people with diabetes (PWD) and is frequently asymptomatic. Screening for silent myocardial ischaemia can be applied in a wide variety of ways. In nearly all asymptomatic PWD, however, the results of screening will generally not change medical therapy, since aggressive preventive measures, such as control of blood pressure and lipids, would have been already indicated, and above all, invasive revascularization procedures (either with percutaneous coronary intervention or coronary artery bypass grafting) have not been shown in randomized clinical trials to confer any benefit on morbidity and mortality. Still, unresolved issues remain regarding the extent of the underlying ischaemia that might affect the risk and the benefit of revascularization (on top of optimal medical therapy) in ameliorating this risk in patients with moderate to severe ischaemia. The issues related to the detection of coronary atherosclerosis and ischaemia, as well as the studies related to management of CHD in asymptomatic PWD, will be reviewed here.

Abstract
BACKGROUND Data of isolated metabolic syndrome as risk factor in patients presenting with acute coronary syndrome (ACS) especially in context to Indian subcontinent are sparse. Therefore, we studied the prevalence of metabolic syndrome (MetS), and its clinical and angiographic profile in naive ACS patients in North Indian population. METHODS A single-center, prospective, observational study of 324 patients was conducted at LPS Institute of Cardiology, G.S.V.M. Medical College, Kanpur, India with newly diagnosed ACS patients with MetS, as per modified NCEP-ATP III criteria. They were divided into two groups with and without MetS, and their clinical and angiographic profiles were studied. RESULTS Prevalence of MetS in our study was 37.65%. Patients with MetS were significantly older than without MetS (60.3 ± 8.4 vs. 57.6 ± 7.9), and had females preponderance (35.24% vs. 24.25%), less tobacco abuse (30.32% vs. 42.57%), more non-ST-segment elevation ACS (58.19% vs. 36.14%), less ST-segment elevation myocardial infarction (STEMI) (41.80% vs. 63.86%), more cardiogenic shock (27.04% vs. 17.32%), recurrent ischemia (14.75% vs. 7.42%) and on angiogram, lesser single vessel disease (21.13% vs. 53.96%), more double vessel disease (39.34 vs. 24.26%), triple vessel disease (19.67% vs. 10.39%), left main (13.11% vs. 4.45%) and complex coronary lesions (tubular 40.98% vs. 31.68%; diffuse 26.23% vs. 18.32%). However, there was a trend of lower but insignificant mortality with MetS (5.44% vs. 6.55%). CONCLUSION There was high prevalence of MetS among patients with ACS in North Indian population with more advanced coronary artery disease. To the best of our knowledge, this is the first study from North India documenting clinical and angiographic profile of patients with MetS and ACS.

Abstract
BACKGROUND South Asians are more prone to develop metabolic syndrome (MetS). The additive predictive value of components of MetS for cardiovascular diseases is still debated. We undertook this study to evaluate the association of MetS and its components with severity of coronary artery disease (CAD). MATERIALS AND METHODS Three hundred patients with known coronary disease above the age of 25 years were included in this study. Blood samples were collected for biochemical markers. Patients were stratified into subjects with and without MetS (International Diabetes Federation, IDF, criteria) and severity of CAD (number of vessel involved). RESULTS Mean age of the patient in the study was 60.9 ± 12.4 years (male, M: 72%; female, F: 28%). MetS was present in 64% patients. Patients with MetS had more severe CAD compared to those without MetS. Triple vessel disease (TVD) was present in 62.5% of patients with MetS compared to 34.3% among without MetS (P < 0.0001). The percent number of patients with TVD showed increasing trend with increasing number of components of MetS (0-0%; 1-20%; 2-27.5%; 3-47.8%; 4-72.6%; 5-78.3%; Chi square for trend < 0.0001). Inflammatory markers [interleukin (IL) 6: 77.67 ± 79.48 vs. 41.21 ± 60.72 pg/ml, P < 0.0001; tumor nuclear factor (TNF)-α: 28.0 ± 47.49 vs 20.43 ± 24.5 pg/ml, P < 0.0001; high sensitive C-reactive protein (hsCRP): 14.30 ± 9.91 vs. 7.02 ± 7.18 mg/L, P < 0.0001], insulin resistance [homeostatic model analysis insulin resistance (HOMA-IR): 22.33 ± 23.37 vs. 10.86 ± 13.90, P < 0.0001] were higher and insulin sensitivity [quantitative insulin check index (QUICKI): 0.26 ± 0.03 vs. 0.30 ± 0.04, P < 0.0001] was significantly lower in subjects with MetS compared to subjects without MetS. Among lipids, total cholesterol were comparable but triglyceride (175 ± 42 vs. 179 ± 48 vs. 180 ± 47 mg/dl, P < 0.0001) was high and high-density lipoprotein (HDL; 44.72 ± 7.63 vs. 39.96 ± 8.70 vs. 36.05 ± 8.84, P < 0.0001) was low in subjects with TVD compared to others. Similarly, percentage of patients with diabetes (7.5% vs. 26.3% vs. 63.7%, P < 0.0001) and hypertension (34.3% vs. 56.6% vs. 77.7%, P < 0.0001) were higher in subjects with TVD compared to others. CONCLUSIONS There is a strong correlation of MetS and its components with severity of CAD.

Abstract
Background. Khat chewing is a common habit in Yemen despite increased evidence of its negative impact on the cardiovascular system. Aims. We aimed to study the epicardial coronary arteries in khat chewers presenting with myocardial infarction (AMI). Materials and Methods. A descriptive, cross-sectional study was conducted between November 2008 and May 2009 in Yemen. AMI patients who underwent coronary angiogram were enrolled and divided into groups (gp): gp1 (diabetic and khat chewers), gp2 (khat chewers and nondiabetic), and gp3 (diabetic and non-khat users). Results. Of 347 AMI patients 63%, 21%, and 16% were in gp 2, 3, and 1, respectively. Khat chewers were younger in comparison to non-khat users. Group 3 patients were more likely to have multivessel disease, severe left anterior descending (LAD), right coronary artery (RCA) stenosis and total RCA, and left circumflex (Lcx) occlusion compared to other groups. Group 1 patients were more likely to have total LAD occlusion and severe Lcx lesions. In multivariate analysis, age, diabetes mellitus, and smoking were significant independent predictors for significant coronary artery lesions; however, khat chewing did not show such association. Conclusions. Coronary spasm is the main mechanism of AMI in khat chewers. The impact of our finding for risk stratification and management warrants further studies.

Abstract
Diabetes mellitus (DM) carries an increased risk for cardiovascular complications. Haptoglobin (Hp) is an abundant plasma protein with an antioxidant function by virtue of its ability to block the oxidative activity of extracorpuscular hemoglobin. There exist two common functional alleles at the Hp genetic locus, denoted 1 and 2, with three Hp genotypes (Hp 1-1, 2-1, and 2-2). The Hp protein expressed in Hp 2-2 individuals is markedly inferior in protecting against hemoglobin-induced oxidative stress. Hp 2-2 DM individuals have been shown to be at increased risk for the development of diabetes complications, particularly diabetic cardiovascular disease (CVD). We review the biological mechanisms underlying the interaction between the Hp genotype and DM on CVD and the accumulating evidence in favor of Hp genotyping all individuals with DM and providing antioxidant vitamin E supplementation specifically to Hp 2-2 DM individuals to reduce their CVD morbidity and mortality.

Abstract
BACKGROUND There are limited data on the contemporary management and outcomes of non-ST-elevation acute coronary syndrome (NSTE-ACS) patients with diabetes in the "real world." We sought to evaluate (1) the temporal changes in the medical and invasive management and (2) in-hospital outcome of NSTE-ACS patients with and without diabetes. METHODS We included Canadian patients hospitalized for NSTE-ACS enrolled in 4 consecutive, prospective, multicenter registries: Canadian ACS-I (n = 3259; 1999-2001), ACS-II (n = 1,956; 2002-2003), Global Registry of Acute Coronary Events (GRACE/GRACE2 [n = 7,561; 2004-2007]) and Canadian Registry of Acute Coronary Events (n = 1,326; 2008). Participants were stratified by the presence or absence of preexisting diabetes on admission. Temporal changes in patient management and outcomes were evaluated across the 4 registries. Multivariable analyses were performed to determine the independent prognostic significance of diabetes. RESULTS Of the 14,102 NSTE-ACS patients, 4,046 (28.7%) had previously diagnosed diabetes. Patients with diabetes were older; were more likely to have prior cardiac history including myocardial infarction, revascularization, and heart failure; and had worse Killip class and higher GRACE risk score (all P < .001). Over time, there were significant increases in the use of in-hospital coronary angiography and revascularization. However, diabetic patients were less likely to undergo coronary angiography (52.5% vs 57%, P < .001) or revascularization (28.4% vs 33.4%, P < .001). The underuse of invasive procedures in diabetic patients was seen in all registries and was persistent over time. Overall, compared with the group without diabetes, diabetic patients had higher unadjusted rates of in-hospital mortality (3.0% vs 1.6%, P < .001). In multivariable analysis adjusting for components of the GRACE risk score, diabetes remained an independent predictor of in-hospital death (adjusted odds ratio 1.66, 95% CI 1.30-2.11, P < .001). CONCLUSIONS Over the last decade, NSTE-ACS patients with diabetes continue to be treated more conservatively, despite evidence that they would derive similar or even greater benefits from aggressive treatment. This underutilization of evidence-based therapies among diabetic patients with NSTE-ACS in the "real world" may partly explain their worse outcome.

Abstract
OBJECTIVE To evaluate the effect of prior duration of diabetes, glycated hemoglobin level at study entry, and microalbuminuria or macroalbuminuria on the extent and severity of coronary artery disease (CAD) and peripheral arterial disease. PATIENTS AND METHODS We studied baseline characteristics of the 2368 participants of the BARI 2D (Bypass Angioplasty Revascularization Investigation 2 Diabetes) study, a randomized clinical trial that evaluates treatment efficacy for patients with type 2 diabetes and angiographically documented stable CAD. Patients were enrolled from January 1, 2001, through March 31, 2005. Peripheral arterial disease was ascertained by an ankle-brachial index (ABI) of 0.9 or less, and extent of CAD was measured by presence of multivessel disease, a left ventricular ejection fraction (LVEF) of less than 50%, and myocardial jeopardy index. RESULTS Duration of diabetes of 20 or more years was associated with increased risk of ABI of 0.9 or less (odds ratio [OR], 1.54; 95% confidence interval [CI], 1.04-2.26), intermittent claudication (OR, 1.61; 95% CI, 1.10-2.35), and LVEF of less than 50% (OR, 2.03; 95% CI, 1.37-3.02). Microalbuminuria was associated with intermittent claudication (OR, 1.53; 95% CI, 1.16-2.02) and ABI of 0.9 or less (OR, 1.31; 95% CI, 0.98-1.75), whereas macroalbuminuria was associated with abnormal ABI, claudication, and LVEF of less than 50%. There was a significant association between diabetes duration and extent of CAD as manifested by number of coronary lesions, but no other significant associations were observed between duration of disease, glycated hemoglobin levels, or albumin-to-creatinine ratio and other manifestations of CAD. CONCLUSION Duration of diabetes and microalbuminuria or macroalbuminuria are important predictors of severity of peripheral arterial disease and left ventricular dysfunction in a cohort of patients selected for the presence of CAD.

Abstract
BACKGROUND It is well known that diabetes mellitus (DM) is a crucial risk factor for coronary artery disease (CAD). The present study aimed to investigate angiographic profiles of the coronary arteries in diabetic CAD patients in comparison with nondiabetics. METHODS A total of 546 Chinese patients were angiographically documented for CAD, 375 of whom were diabetics and 171 were nondiabetics according to the WHO diabetes criteria (1999). The patients in these two groups were matched for age, sex, and body mass index (BMI). The 75 g oral glucose tolerance test (OGTT) was performed in all patients, for whom blood glucose, insulin, glycosylated hemoglobin (HbA1c), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A (ApoA), apolipoprotein B (ApoB), and lipoprotein(a) [Lp(a)] were measured. Insulin resistance (Homa-IR) and insulin secretion index (Homa-IS) were determined by the HOMA model. The clinical features and the data from selective coronary angiographies were compared between the diabetic and nondiabetic CAD patients. RESULTS Diabetic CAD patients had significantly higher waist to hip ratio (WHR) (p=0.016), fasting plasma glucose (FPG), 2h plasma glucose (2hPG), glycosylated hemoglobin (HbA1c) (p<0.001), insulin resistance index (Homa-IR) (p=0.001), and apolipoprotein A (ApoA) (p=0.008), with a significantly lower insulin secretion index (Homa-IS) level (p<0.001). Diabetic patients had one-vessel disease less frequently (28.8% vs 46.2%, p<0.001), and three-vessel disease more frequently (35.2% vs 24.0%, p=0.009), and they also had significantly higher cumulative coronary atherosclerosis score (CAS) (p=0.003). The right coronary artery was significantly more frequently involved in diabetics (66.4% vs 52.6%, p=0.002), with a clearly higher CAS at the same time (p=0.002). CONCLUSIONS Diabetics were presented with more severe and diffuse angiographically documented coronary artery disease compared to nondiabetics. The right coronary artery was significantly more frequently involved in the diabetics. Duration of CAD, Homa-IR, and diabetes mellitus were the independent risk factors for CAD found in the present study, while ApoA was the protective one.

Abstract
OBJECTIVE Coronary artery disease (CAD) risk increases in women after the menopause. The aim of this study was to determine the effect of diabetes on the severity of CAD in postmenopausal women undergoing coronary angiography. DESIGN 180 postmenopausal women underwent coronary angiography for suspected CAD. CAD severity was assessed by the number of arteries (0-3) with >50% stenosis in the angiography. Forty-four women had type 2 diabetes mellitus (T2DM). Predisposing risk factors and biochemical and hormonal parameters were recorded. The diabetic women were older (p=0.014), had higher BMI and waist circumference (p<0.001), higher prevalence of hypertension (p=0.002), higher levels of triglycerides, uric acid and higher HOMA-Insulin Resistance Index (p=0.009). RESULTS The women with diabetes had a higher prevalence of severe stenosis in the angiography: T2DM: 0-vessels 25%, 1-vessel disease 18.2%, 2-vessels disease 22.7%, 3-vessels disease 34.1%, vs. 49.2%, 23.5%, 22.1%, 5.1% in the non-diabetic women, respectively (p<0.001). Binary logistic regression analysis showed that T2DM was a significant predictor of severe CAD (>or=3 vessel disease) independently of age, family history of T2DM, BMI, time since menopause, hypertension and hypercholesterolemia. Women with T2DM also had lower sex hormone binding globulin (SHBG, p=0.010) levels compared to non-diabetic women. CONCLUSIONS Diabetic postmenopausal women develop more severe CAD compared to non-diabetic women. This association is independent of other predisposing factors and suggests an independent effect of T2DM on the atherosclerotic process, at least in women after menopause.

Abstract
Screening, diagnosis and revascularization of coronary artery disease (CAD) in type 2 diabetes mellitus are major challenges for current clinical practice. Diagnostic (angiography) and therapeutic (angioplasty) cardiac catheterization are important resources for the clinical assessment and management of coronary atherosclerosis. Anatomic peculiarities of CAD in diabetics can be well characterized by angiography, associated or not by intravascular ultrasound. The worse outcome following coronary revascularization procedures, either angioplasty or surgery, in diabetic is one of the main fields of clinical research. In spite of controversies, about one quarter of angioplasty and one third of surgical revascularization procedures are performed in diabetics. Two ongoing, large, randomized, multicentric trials are investigating the best management of CAD in diabetics. The BARI 2D trial is randomizing asymptomatic or mildly symptomatic patients with CAD for either medical therapy or revascularization (angioplasty or surgery, according to the best clinical judgment). The FREEDOM trial is randomizing stable patients with multivessel CAD for either angioplasty with drug eluting stents or surgery, with or without extracorporeal circulation. While the evidences are not available, in order to decide on the best revascularization procedure for individual patients, medical practice has been balanced according to a number of variables. Conditions that favor angioplasty: short lesions, lesions in large vessels, absence of left anterior descending artery disease, previous coronary bypass surgery and high surgical risk due to co-morbidities. Conditions that favor surgery: long lesions, lesions in small vessels, presence of left anterior descending artery disease and need for associated valve surgery.

Abstract
BACKGROUND : The arguments are discussed as to whether or not to proceed with multivessel percutaneous coronary intervention, with or without a drug-eluting stent, in patients with diabetes mellitus (DM), including (1) surgeons unable to complete revascularization because of smaller native arteries; and (2) diabetic patients being sicker and having higher operative mortality rates than nondiabetic patients (non-DM), particularly with the conventional coronary artery bypass surgery (on-pump) technique. To support or dispute the claims, a retrospective review of 480 consecutive patients at a single institution (195 DM and 285 non-DM) was carried out. Observations were made to see whether diabetes is a predictor of poor outcomes. MATERIALS AND METHODS : The preoperative comorbidity, intraoperative measurement of the size of the artery at the site of anastomosis with different gauged probes, and the number of grafts per patient were recorded. Intraoperative and postoperative variables between two groups were compared. The observed number of grafts (O) after surgery was compared with the number of grafts predicted (P) before surgery. The O/P ratio or "completion index" of ≥1 signifies complete revascularization. Logistic regression analysis was used to test the possibility that diabetes is a predictor of poor outcomes. RESULTS : Diabetic patients were older, with more comorbidity (congestive heart failure, peripheral vascular diseases, dialysis-dependent). The number of grafts per patient was 4.2 ± 1.3 (DM) and 4.2 ± 1.3 (non-DM). The size of 742 DM and 949 non-DM arteries were gauged. There was no statistical difference in size between DM and non-DM (in millimeters) at each artery. All ratios ranged from 0.9 to 1.2, indicating similarity between DM and non-DM. The only significant risk factor for operative death was low left ventricular ejection fraction (P = 0.001). CONCLUSIONS : Patients with DM were sicker but tolerated off-pump coronary artery bypass grafting as well as non-DM patients. The number of grafts per patient and O/P ratio signify the ability to perform complete revascularization. We are able to bypass the small target vessels, as anticipated. Diabetes is not a predictor of the outcomes.

Abstract
Diabetes mellitus is a disease, which is at the epitome of cardiovascular risk factors causing considerable morbidity and mortality. In addition to microvascular complications, there is two- to six-fold increased risk of macrovascular diseases, such as coronary artery disease, peripheral artery disease and stroke. While the mortality from coronary artery disease in patients without diabetes has declined over the past 20 years, the mortality in men with type 2 diabetes mellitus has not changed. Furthermore, the prevalence of diabetes in the UK has increased by 30% since 1991 and the same among the world population in 2010 is expected to be twice in 1990. This dramatic increase has serious implications from a cardiovascular perspective and thus the aggressive management of blood pressure, dyslipidaemia and blood glucose in diabetes is of vital importance. The aim of this review is to evaluate the current evidence and to discuss the implications of type 2 diabetes and its relevance to clinical practice in cardiology. We address this broad subject in discussing (i) the pathophysiology of cardiovascular disease in the setting of type 2 diabetes and (ii) the prevalence of cardiovascular risk, complications and prognostic implications in type 2 diabetes, with a discussion of current therapeutic interventions for the prevention or delay of these consequences where relevant.

Abstract
There are over 1.3 million known diabetic patients in the UK and a similar number who have the disease undiagnosed. Over 90% have non-insulin dependent diabetes mellitus usually characterised by insulin resistance and adult onset. Over half of all diabetic patients die of coronary disease and account for over a fifth of percutaneous coronary intervention (PCI) revascularisation procedures. Despite recent therapeutic advances such as new antiplatelet treatments and drug eluting stents, outcomes for diabetic patients after PCI are still significantly worse than for non-diabetic patients. This article summarises what is known about the pattern and severity of diabetic coronary disease, what mechanisms are responsible for these differences, and whether this information can help explain the poorer prognosis for these patients after PCI and form the basis of interventions to improve outcome.

Abstract
Patients with diabetes mellitus (DM) have more severe coronary artery disease and a two- to fourfold higher risk for myocardial infarction and death as compared to patients without DM. In this study, we analyzed coronary anatomy, left ventricular ejection fraction, and cardiac risk factors in patients with DM referred for coronary angiography and compared them with findings in nondiabetic patients. Coronary anatomy was assessed in a total of 6,234 patients and left ventricular ejection fraction in a subset of 4,767 (76.5%) patients. Diabetic patients (n = 641) were older (60.8 +/- 9.6 vs. 58.5 +/- 10.5 years; P < 0.0001) and had higher rates of hypertension (65% vs. 47%; P < 0.0001). Three-vessel disease (DM 44.7% vs. no DM 25.4%; P < 0.0001) and reduced left ventricular ejection fraction (DM 58.4% +/- 15.2 vs. no DM 63.9% +/- 13.2; P < 0.0001) were significantly associated with DM. After adjustment for age and other vascular risk factors, the presence of DM was associated with a higher atherosclerotic burden. We conclude that advanced coronary heart disease and left ventricular dysfunction are highly prevalent in diabetic patients, independent of age and other cardiovascular risk factors. Thus, cardiac assessment in diabetic patients should, in addition to optimal diabetic control, involve screening for left ventricular dysfunction.

Abstract
Clusterin/apolipoprotein J (hereafter ApoJ) is a conserved secreted glycoprotein expressed by a wide array of tissues and being implicated in several physiological processes. ApoJ has been shown to associate with both normal in vitro aging, namely replicative senescence, as well as with stress induced premature senescence. In vivo, the protein is up-regulated in many severe physiological disturbances that relate to advanced aging, including accumulation in the artery wall during the development of atherosclerosis. In the current report we have expanded our previous studies that focus in the biological role of ApoJ during aging by addressing two interrelated issues: (a) we have examined the potential ApoJ association with in vivo aging and (b) we have studied whether its accumulation in the artery wall during the development of atherosclerosis is combined with a measurable increase of its serum levels, as well as, whether a similar effect occurs in diseases, such as diabetes type II, known to represent major risk factors of atherosclerosis. By combining a sandwich ELISA assay and immunoblotting analysis we demonstrate a measurable increase of ApoJ serum levels with age in males and provide evidence that, as compared to healthy donors, the serum ApoJ amount increases significantly in diabetic type II patients and in patients suffering from either a developing coronary heart disease, or myocardial infarction. The highest serum ApoJ levels were found during myocardial infarction but no correlation was observed with the number of vessels with documented atherosclerotic damage. In conclusion, this report illustrates that ApoJ accumulation in serum is probably coupled to a generalized stress mediated induction mechanism that is specifically related to certain diseases; moreover these data raise the possibility that elevated ApoJ levels in serum may represent a strong indication of vascular damage.
