Abstract Background Postprandial hyperglycemia was reported to play a key role in established risk factors of coronary artery diseases (CAD) and cardiovascular events. Serum 1,5-anhydroglucitol (1,5-AG) levels are known to be a clinical marker of postprandial hyperglycemia and short-term glycemic excursions. Low serum 1,5-AG levels have been associated with occurrence of CAD; however, the relationship between 1,5-AG levels and coronary plaque rupture has not been fully elucidated. The aim of this study was to evaluate 1,5-AG as a predictor of coronary plaque rupture in diabetic patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS). Methods A total of 132 diabetic patients with NSTE-ACS were included in this study. All patients underwent intravascular ultrasound examination, which revealed 38 patients with plaque rupture and 94 patients without plaque rupture in the culprit lesion. Fasting blood glucose (FBS), hemoglobin A1c (HbA1c) and 1,5-AG levels were measured before coronary angiography. Fasting urinary 8-iso-prostaglandin F2α (8-iso-PGF2α) level was measured and corrected by creatinine clearance. Results Patients with ruptured plaque had significantly lower serum 1,5-AG levels and a tendency of higher hemoglobin A1c levels than patients without ruptured plaque in our study population. In multivariate analysis, low 1,5-AG levels were an independent predictor of plaque rupture (odds ratio 3.3; p=0.006) in diabetic patients with NSTE-ACS, but HbA1c was not. The area under the receiver-operating characteristic curve for 1,5-AG (0.678, p=0.001) to predict plaque rupture was superior to that for HbA1c (0.618, p=0.034). Levels of 1,5-AG were significantly correlated with urinary 8-iso-PGF2α (r=−0.224, p=0.010). Conclusions Postprandial hyperglycaemia appeared to be superior to long-term average blood glucose levels in predicting plaque rupture in culprit lesions, which may be useful to assess the cardiovascular outcomes in diabetic patients.

Background/Aim. Matrix metalloproteinase-9 (MMP-9) index is the ratio of active MMP-9 and total MMP-9 levels. It reflects the importance of MMP-9 in acute coronary syndrome (ACS). Methods. The study included 3 groups of patients (n = 87): the group 1 - non-diabetic subjects without ACS (control); the group 2 - diabetic patients with ACS [subgroups with unstable angina pectoris (UAP), myocardial infarction (MI) or reinfarction]; and the group 3 non-diabetics patients with ACS. Total and active MMP-9 were measured and used to create MMP-9 index. Results. MMP-9 index, as a marker showed good sensitivity and specificity, of ACS in diabetics, with a cut-off value over 58.2. MMP-9 was higher in the study groups than in the control one. MMP-9 correlated with ACS occurrence and type of cardiovascular event. A statistically significant difference was found among the groups according to active MMP-9 (p < 0.001). The same was found with active MMP-9 between the control and the group with MI (p < 0.001). The control was highly statistically significantly different from the group of patients with UAP (p < 0.01). Statically significant differences in MMP-9 index was found between the control and the diabetics with ACS (p < 0.001). Statistically significant difference of MMP-9 index was also found in the controls compared to the value in non-diabetic patients with ACS (p < 0.01). Conclusion. MMP-9 index may be a possible marker of atheromatous plaque rupture in diabetics.

Abstract Background The importance of monocyte-to-lymphocyte ratio (MLR) has been indicated in the initiation and progression of coronary artery disease (CAD). However, few previous researches demonstrated the relationship between MLR and plaque vulnerability. We aimed to investigate coronary plaque vulnerability in patients with acute coronary syndrome (ACS) by optical coherence tomography (OCT). Methods A total of 72 ACS patients who underwent coronary angiography and OCT test in Beijing Anzhen hospital were included in this retrospective study. The plaque vulnerability and plaque morphology were assessed by OCT. Results The coronary plaque in high MLR group exhibited more vulnerable features, characterizing as thinner thickness of fibrous cap (FCT)(112.37 ± 60.24 vs 153.49 ± 73.29 μm, P = 0.013), greater maximum lipid core angle (167.36 ± 62.33 vs 138.79 ± 56.37°, P = 0.010) and longer lipid plaque length (6.34 ± 3.12 vs 4.50 ± 2.21mm, P = 0.041). A prominently negative liner relation was found between MLR and FCT (R = 0.225, P < 0.005). Meanwhile, the incidence of OCT-detected thin cap fibro-atheroma (TCFA) (44.7% vs 18.4%, P = 0.014) and plaque rupture (36.8% vs 13.2%, P = 0.017) were higher in high MLR group. Most importantly, multivariable logistic regression analysis showed MLR level was related to the presence of TCFA (OR:3.316,95%:1.448-7.593,P = 0.005). MLR level could differentiate TCFA with a sensitivity of 72.0% and a specificity of 66.1%. Conclusion Circulating MLR level has potential value in identifying the presence of vulnerable plaque in patients with ACS. MLR, as a non- invasive biomarker of inflammation, may be valuable in revealing plaque vulnerability. Key words Monocyte-to-lymphocyte ratio, Optical coherence tomography, Plaque vulnerability

Abstract Aims Atherosclerotic plaque healing is a dynamic process developing after plaque rupture or erosion, which aims to prevent lasting occlusive thrombus formation and to promote plaque repair. We hypothesized that diabetes mellitus, one of the major conventional cardiovascular risk factors, may influence the healing capacity after plaque destabilization. Methods and results In this single-centre observational cohort study, patients with acute coronary syndrome (ACS) or chronic coronary syndrome (CCS) who underwent optical coherence tomography (OCT) imaging at Fondazione Policlinico A. Gemelli–IRCCS, Rome, were included. Patients were divided into two groups (i.e. diabetes vs. no diabetes), and stratified based on diabetes medications (i.e. insulin, vs. oral antidiabetic drugs). OCT analysis of non-culprit coronary segments was performed. 105 patients were included (44 diabetes, 61 no diabetes). Prevalence of HCPs was not significantly different between patients with and without diabetes (3.6% vs. 3.8%, P = 0.854). However, patients with diabetes on insulin showed a lower prevalence of HCPs both at patient-based (7.1% vs. 26.4%, P = 0.116) and at segment-based analysis (1.2% vs. 4.2%, P = 0.020). When comparing HbA1c levels based on the presence or absence of healed plaque at the non-culprit lesions, patients with healed plaque showed significantly lower levels of HbA1c compared to patients without healed plaques (43.5 ± 12.1% vs. 61.2 ± 10.4%, P &lt; 0.001). At segment-based analysis, normal vessel structure, pathological intimal thickening (PIT), and spotty calcifications were significantly less prevalent in diabetic patients (2.1% vs. 5.1%, P = 0.001; 7.2% vs. 9.5%, P = 0.05; 9.9% vs. 13.6%, P = 0.02, respectively), whereas neovascularization was significantly higher (19.2% vs. 15.6%, P = 0.035). Conclusions Patients with diabetes have a distinct coronary non-culprit plaque phenotype. Healing capacity may be impaired in patients with advanced diabetes on insulin therapy and in those with a suboptimal control of the disease. Further prospective, larger scale studies are warranted to confirm these findings.
