Abstract Background Patients with diabetes mellitus (DM) may have elevated levels of high-sensitive cardiac troponin (hs-Tn) despite acute myocardial ischemia being present. However, it is unclear whether this constrains diagnostic strategies in patients with suspected acute myocardial infarction (MI). Purpose We aimed to assess the diagnostic performance of the European Society of Cardiology (ESC) 0/1 hour (h) and 0/3h-algorithms comparing patients with and without DM and to derive optimized cut-offs. Methods We prospectively enrolled patients with symptoms suggestive of MI in two large clinical cohorts and measured hs-TnI at admission (baseline) and 1 (cohort A) and 3h (cohort A+B) thereafter. Patients with ST-elevation MI were excluded. Patients were stratified based on a diagnosis of DM at baseline. Final diagnoses were adjudicated independently by two cardiologists using all clinically available information, including hs-TnT, but blinded to hs-TnI values. Our primary outcomes of interest were safety of rule-out (defined by sensitivity and negative predictive value [NPV]), accuracy of rule-in (defined by specificity and positive predictive value [PPV]) and the overall performance (% of patients adjudicated to either rule-out or -in). For optimized cut-offs, a NPV >99.0% and a PPV >75.0% were targeted. Results DM was prevalent in 563 (15.29%) of 3683 included patients. MI was more prevalent among patients with DM (137 [24.3%] vs. 498 [16.0%], p<0.001). Using the ESC 0/1h-algorithm (Figure), rule-out was safe in diabetics (p for sensitivity = 1.00) with higher NPV in non-diabetics (p<0.001), while the proportion of patients ruled-out was smaller in diabetics (22.3% vs. 41.8%). Accuracy of rule-in was significantly lower in diabetics (specificity p=0.0035, PPV p=0.48), with a higher rule-in rate of patients with DM (29.5% vs. 21.8%). Using the ESC 0/3h-algorithm, safety of rule-out was lower in both groups compared to the ESC 0/1h-algorithm, with again higher NPV for non-DM (sensitivity p=0.18, NPV p<0.001) and a higher proportion of non-DM ruled-out (65.9% vs. 75.2%). Accuracy of rule-in was significantly lower for patients with DM (specificity p=0.0094, PPV p=0.87). Cut-off adjustment to yield pre-defined accuracy measures resulted in: 4ng/L at baseline or 6ng/L with a delta of 2ng/l for rule–out and 90ng/L or a delta of 10ng/L for rule-in with the ESC 0/1h algorithm; for the ESC 0/3h-algorithm cut-offs were 5ng/L with a delta of 20% for rule-out and 50ng/L with a delta of 20% for rule-in. Conclusion Application of the ESC 0/1h- and 0/3h-algorithms in diabetic patients provided reduced safety and accuracy for rule-out and rule-in of MI, respectively. Use of alternative cut-offs resulted in improved diagnostic safety and accuracy.

Abstract Background Acute hyperglycemia has been recognized as a robust predictor for occurrence of acute kidney injury (AKI) in nondiabetic patients with acute myocardial infarction (AMI), however, its discriminatory ability for AKI is unclear in diabetic patients after an AMI. Here, we investigated whether stress hyperglycemia ratio (SHR), a novel index with the combined evaluation of acute and chronic glycemic levels, may have a better predictive value of AKI as compared with admission glycemia alone in diabetic patients following AMI. Methods SHR was calculated with admission blood glucose (ABG) divided by the glycated hemoglobin-derived estimated average glucose. A total of 1215 diabetic patients with AMI were enrolled and divided according to SHR tertiles. Baseline characteristics and outcomes were compared. The primary endpoint was AKI and secondary endpoints included all-cause death and cardiogenic shock during hospitalization. The logistic regression analysis was performed to identify potential risk factors. Accuracy was defined with area under the curve (AUC) by a receiver-operating characteristic (ROC) curve analysis. Results In AMI patients with diabetes, the incidence of AKI (4.4%, 7.8%, 13.0%; p < 0.001), all-cause death (2.7%, 3.6%, 6.4%; p = 0.027) and cardiogenic shock (4.9%, 7.6%, 11.6%; p = 0.002) all increased with the rising tertile levels of SHR. After multivariate adjustment, elevated SHR was significantly associated with an increased risk of AKI (odds ratio 3.18, 95% confidence interval: 1.99–5.09, p < 0.001) while ABG was no longer a risk factor of AKI. The SHR was also strongly related to the AKI risk in subgroups of patients. At ROC analysis, SHR accurately predicted AKI in overall (AUC 0.64) and a risk model consisted of SHR, left ventricular ejection fraction, N-terminal B-type natriuretic peptide, and estimated glomerular filtration rate (eGFR) yielded a superior predictive value (AUC 0.83) for AKI. Conclusion The novel index SHR is a better predictor of AKI and in-hospital mortality and morbidity than admission glycemia in AMI patients with diabetes.

Abstract Background Several studies compared everolimus-eluting bioresorbable scaffolds (EE-BRS) with everolimus-eluting stents (EES), but only few assessed these devices in patients with diabetes mellitus. Aim To evaluate the safety and efficacy outcomes of all-comer patients with diabetes mellitus up to 2 years after treatment with EE-BRS or EES. Methods We performed a post hoc pooled analysis of patient-level data in diabetic patients who were treated with EE-BRS or EES in 3 prospective clinical trials: The ABSORB DM Benelux Study (NTR5447), TWENTE (NTR1256/NCT01066650) and DUTCH PEERS (NTR2413/NCT01331707). Primary endpoint of the analysis was target lesion failure (TLF): a composite of cardiac death, target vessel myocardial infarction or clinically driven target lesion revascularization. Secondary endpoints included major adverse cardiac events (MACE): a composite of all-cause death, any myocardial infarction or clinically driven target vessel revascularization, as well as definite or probable device thrombosis (ST). Results A total of 499 diabetic patients were assessed, of whom 150 received EE-BRS and 249 received EES. Total available follow-up was 222.6 patient years (PY) in the EE-BRS and 464.9 PY in the EES group. The adverse events rates were similar in both treatment groups for TLF (7.2 vs. 5.2 events per 100 PY, p = 0.39; adjusted hazard ratio (HR) = 1.48 (95% confidence interval (CI): 0.77–2.87), p = 0.24), MACE (9.1 vs. 8.3 per 100 PY, p = 0.83; adjusted HR = 1.23 (95% CI: 0.70–2.17), p = 0.47), and ST (0.9 vs. 0.6 per 100 PY, p > 0.99). Conclusion In this patient-level pooled analysis of patients with diabetes mellitus from 3 clinical trials, EE-BRS showed clinical outcomes that were quite similar to EES.

Abstract. Recently, quantitative analysis of the level of the N-terminal prohormone of the brain naturetic peptide (NT-proBNP) has been widely used to diagnose heart failure (HF). A statistically significant correlation was found between the serum NT-proBNP concentration and HF stage. It was found that in patients with high cardiovascular risk, NT-proBNP has the highest predictive value in relation to mortality. In young and middle-aged patients with diabetes mellitus (DM) with myocardial infarction (MI) and stents of an infarct-associated artery, the frequency of unfavorable remodeling (UR) of the left ventricle (LV) in the long-term prognosis was studied. The frequency of atherosclerotic lesions of the coronary arteries (CA) in patients with diabetes in acute coronary syndrome (ACS) was determined, the results of echocardiographic parameters were presented in the follow-up dynamics, the value of serum NT-proBNP in predicting LV UR 12 months after myocardial infarction (MI) was determined.Aim of study. To assess the diagnostic capabilities of NT-proBNP in the long-term prediction of the development of LV infarction in patients with MI with diabetes in young and middle age after percutaneous coronary intervention (PCI).Design. Prospective controlled non-randomized trial. The patients were examined twice: on the first day of ACS after PCI with stenting of infarct-associated coronary artery and 12 months after AMI. The study included 191 patients with ACS with / without ST-segment elevation, who were divided into two groups. The main group included 76 patients with ACS with diabetes mellitus, the comparison group included 115 patients with ACS without diabetes mellitus. Patients in both groups were comparable in age, gender, comorbidity, and complications of AMI. The duration of diabetes was, on average, 6 years (from one to 12 years).Material and methods. All patients underwent electrocardiography, echocardiography, tests for the content of troponin I, NT-proBNP, glycosylated hemoglobin, lipids, determined the level of creatinine in the blood and the glomerular filtration rate according to the Modification of diet in renal disease (MDRD). All patients were examined twice: on the first day of ACS after PCI with stenting of infarct-associated coronary artery and 12 months later.Results. In 69% of diabetic patients with anterior myocardial infarction and in 63% of patients with posterolateral MI 12 months after PCI, signs of LV inferiority were revealed in the form of an increase in the indices of end-diastolic and systolic volumes of the LV and low ejection fraction (≤45%). In patients without diabetes, these figures were 18% and 31%, respectively. High concentrations of NT-proBNP on the first day of myocardial infarction after PCI were of the greatest value in the diagnosis and prognosis of LV UR after 12 months.Conclusion. The NT-proBNP level of more than 776 pg/ml on the first day after PCI is an indicator of an unfavorable long-term prognosis in patients with young and middle-aged diabetes in terms of the development of LV systolic dysfunction.

<p>Sudden death with myocardial infarction has always<br />been a challenging issue for the investigators and<br />forensic pathologists. When a person suffering from<br />angina or myocardial infarction is simultaneously<br />suffering from diabetes mellitus issue becomes even<br />more complex for the investigators as usual signs &amp;<br />symptoms of MI may not manifest so as to rouse a<br />suspicion of MI. This study will help the pathologists to<br />understand the microscopic changes of diabetic<br />cardiomyopathy better in a case having MI with<br />diabetes. This study was done in 47 cases to know the<br />pathology of microvasculature and cardiomyocytes in<br />myocardial tissue of diabetic patients and expression of<br />angiogenic factors.</p>

Background Patients with diabetes mellitus (DM) are known to be at high-risk for both ischemic and bleeding complications post-percutaneous coronary intervention (PCI). The ischemic benefit versus bleeding risk associated with extended dual antiplatelet therapy (DAPT) in high-risk "TWILIGHT-like" patients with diabetes mellitus after PCI has not been established. Methods All consecutive high-risk patients fulfilling the "TWILIGHT-like" criteria undergoing PCI from January 2013 through December 2013 were identified from prospective Fuwai PCI Registry. High-risk "TWILIGHT-like" patients were defined by at least 1 clinical and 1 angiographic feature based on TWILIGHT trial selection criteria. The present analysis evaluated 3425 diabetics patients with concomitant high-risk angiographic features who were event-free at 1 year after PCI. Median follow-up was 2.4 years. The primary effectiveness endpoint was a composite of death, myocardial infarction, or stroke (termed major adverse cardiac and cerebrovascular events) and primary safety endpoint was clinically relevant bleeding according to Bleeding Academic Research Consortium type 2, 3, or 5. Results On inverse probability of treatment weighting (IPTW) analysis, prolonged-term (&gt;1-year) DAPT with aspirin and clopidogrel decreased the risk of primary effectiveness endpoint compared with shorter (≤1-year) DAPT (1.8% vs. 4.3%; hazard ratio [HR]IPTW: 0.381; 95% confidence interval [CI]: 0.252-0.576; P &lt; 0.001) and reduced cardiovascular death (0.1% vs. 1.8%; HRIPTW: 0.056 [0.016-0.193]). Prolonged DAPT was also associated with a reduced risk of definite/probable stent thrombosis (0.2% vs. 0.7%; HRIPTW: 0.258 [0.083-0.802]), and non-significantly lower rate of myocardial infarction (0.5% vs. 0.8%; HRIPTW: 0.676 [0.275-1.661]). There was no significant difference between groups in clinically relevant bleeding (1.1% vs. 1.1%; HRIPTW: 1.078 [0.519-2.241]; P = 0.840). Similar results were observed in multivariable Cox proportional hazards regression model. Conclusion Among high-risk PCI patients with diabetes mellitus without an adverse event through 1 year, extending DAPT &gt; 1-year significantly reduced the risk of major adverse cardiac and cerebrovascular events without an increase in clinically relevant bleeding, suggesting that such high-risk diabetic patients may be good candidates for long-term DAPT.

BACKGROUND: Acute coronary occlusions occur most frequently as a result of rupture of an atherosclerotic plaque. Previous studies have found greater extent of atherosclerotic disease in the coronary arteries of diabetic patients. While the burden of disease is higher in diabetics, less is known about the spatial distribution of myocardial infarction in this population. METHODS: We sought to compare the spatial distribution of myocardial infarction (STEMI and Non-STEMI) in patients with diabetes mellitus and in those without, based on quantitative coronary and statistical analysis. We analyzed 756 patients with STEMI (n = 556) and NSTEMI (n=200), of which 175 patients comprised the diabetic cohort, and mapped the location of the acute coronary occlusion. RESULTS: Coronary occlusions were not uniformly distributed throughout each of the major epicardial coronary arteries but tended to cluster within the proximal third of each of the vessels in both cohorts. There was no difference in the distribution of occlusions in diabetics vs. non-diabetics in any of the vessels (left anterior descending artery, P=0.35; left circumflex artery; P=0.33 right coronary artery, P=0.20; Figure). CONCLUSIONS: Acute coronary occlusions leading to STEMI and NSTEMI in both diabetics and non-diabetics tend to cluster in predictable “hot spots” within the proximal third of the coronary arteries. Identification of these high-risk zones for acute coronary occlusions will lead to future advances in vulnerable plaque detection technology and potentially locally directed preventive strategies. Spatial distribution of myocardial infarction in diabetics vs. non-diabetics using distance to lesion from the ostium of the coronary artery.

Patients with diabetes mellitus have been shown to have an increased incidence of complications after major vascular surgery. The objective of this study was to evaluate the results of carotid endarterectomy in diabetic patients, to determine if results differ from nondiabetic patients, and to examine the risk factors for poor outcome among diabetic patients. Material and methods. We reviewed all carotid endarterectomies performed in Emergency Hospital of Vilnius University. From 1995 to 2005, 707 carotid endarterectomies were performed. Of these, 100 operations were performed in diabetic patients (14%) and the remaining 607 in nondiabetic patients. Results. Diabetic patients were younger (P<0.05) and were obese more often (P<0.001), they smoked less often (P<0.001) than nondiabetic patients. Diabetics were more likely to have severe bilateral carotid stenosis than nondiabetic patients (P<0.01). Postoperative complications (stroke) were more common in diabetic patients than in nondiabetic patients (12.0% vs. 3.4%, P<0.001) as well as intracerebral hemorrhages (3.0% vs. 0.3%, P<0.001); no perioperative myocardial infarction was found in diabetic patients. Risk factors for complications were age ≥75 (odds ratio (OR) 2.2; 95% confidence interval (CI)=1.0–4.9), smoking (OR 2.7; 95% CI=1.8– 4.2), obesity (OR 6.1; 95% CI=3.9–9.5), and bilateral carotid stenosis (OR 2.1; 95% CI=1.3–3.6). Conclusion. Diabetes mellitus significantly increased the risk of mortality and intracerebral hemorrhage but not myocardial infarction. It should be taken into consideration in making decisions about the performance and perioperative management of carotid endarterectomy.
