Abstract
Despite the decades-old knowledge that diabetes mellitus is a major risk factor for cardiovascular disease, the reasons for this association are only partially understood. While this association is true for both type 1 and type 2 diabetes, different pathophysiological processes may be responsible. Lipids and other risk factors are indeed important, whereas the role of glucose is less clear. This lack of clarity stems from clinical trials that do not unambiguously show that intensive glycemic control reduces cardiovascular events. Animal models have provided mechanisms that link diabetes to increased atherosclerosis, and evidence consistent with the importance of factors beyond hyperglycemia has emerged. We review clinical, pathological, and animal studies exploring the pathogenesis of atherosclerosis in humans living with diabetes and in mouse models of diabetes. An increased effort to identify risk factors beyond glucose is now needed to prevent the increased cardiovascular disease risk associated with diabetes.

Abstract
Atherosclerosis is a chronic inflammatory disease. Several circulating inflammatory markers have been proposed for clinical use due to their ability to predict future cardiovascular events and may be useful for identifying people at high risk who might benefit from specific treatment to reduce this risk. Moreover, the identification of new therapeutic targets will allow the development of drugs that can help reduce the high residual risk of recurrence of cardiovascular events in patients with coronary artery disease. The clinical benefits of reducing recurrent major cardiovascular events recently shown by canakinumab and colchicine have renewed the cardiology community’s interest in inflammation as an aetiopathogenic mechanism for atherosclerosis. This review explores the use of C-reactive protein, which is the most frequently studied biomarker in this context; the concept of residual risk in primary and secondary cardiovascular prevention; and the current recommendations in international guidelines regarding the role of this inflammatory biomarker in cardiovascular risk stratification.

Abstract
Systemic vascular inflammation plays multiple maladaptive roles which contribute to the progression and destabilization of atherosclerotic cardiovascular disease (ASCVD). These roles include: (i) driving atheroprogression in the clinically stable phase of disease; (ii) inciting atheroma destabilization and precipitating acute coronary syndromes (ACS); and (iii) responding to cardiomyocyte necrosis in myocardial infarction (MI). Despite an evolving understanding of these biologic processes, successful clinical translation into effective therapies has proven challenging. Realizing the promise of targeting inflammation in the prevention and treatment of ASCVD will likely require more individualized approaches, as the degree of inflammation differs among cardiovascular patients. A large body of evidence has accumulated supporting the use of high-sensitivity C-reactive protein (hsCRP) as a clinical measure of inflammation. Appreciating the mechanistic diversity of ACS triggers and the kinetics of hsCRP in MI may resolve purported inconsistencies from prior observational studies. Future clinical trial designs incorporating hsCRP may hold promise to enable individualized approaches. The aim of this Clinical Review is to summarize the current understanding of how inflammation contributes to ASCVD progression, destabilization, and adverse clinical outcomes. We offer forward-looking perspective on what next steps may enable successful clinical translation into effective therapeutic approaches-enabling targeting the right patients with the right therapy at the right time-on the road to more individualized ASCVD care.

Fibrinogen-to-albumin ratio predicts long-term outcomes for patients with ST-elevation myocardial infarction and multivessel disease: A prospective observational cohort study. Exp Ther Med 2021; 21:465. [PMID: 33767762 PMCID: PMC7976379 DOI: 10.3892/etm.2021.9896] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 04/21/2020] [Indexed: 12/28/2022] Open
Abstract
The fibrinogen-to-albumin ratio index (FAR) is a valuable tool reflecting the systemic inflammation level and associated with the severity of coronary artery disease. However, the utility of the FAR in predicting the long-term prognosis of patients with ST-elevation myocardial infarction (STEMI) and multivessel disease has remained to be determined. A total of 424 patients diagnosed with STEMI and multivessel disease were recruited for the present study. They were given emergent percutaneous coronary intervention treatment and then completed a follow-up for primary (all-cause mortality) and secondary endpoints (major adverse cardiac events, including MI, stroke, emergent revascularization and rehospitalization due to heart failure). The association between FAR and the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score was investigated, while receiver operating characteristic curve analysis was adopted to assess the ability of the FAR to predict long-term outcomes. The long-term survival of high and low FAR groups was compared by drawing Kaplan-Meier survival curves. Multivariate Cox regression analysis was adopted to evaluate the risk factors of primary and secondary endpoints. The FAR was revealed to have a linear correlation with the SYNTAX score (y=0.022x+17.737; P=0.015). Furthermore, the FAR was a significant predictor of all-cause death with a cut-off value of 128.4 (area under the curve, 0.832; P<0.001). A significant difference was determined between the high FAR group and the low FAR group in terms of the proportion of patients with the primary endpoint (P<0.001) and secondary endpoint (P=0.001). It was demonstrated that the FAR was an independent risk factor for all-cause death of patients with STEMI and multivessel disease (hazard ratio, 1.029; 95% CI: 1.020-1.037; P<0.001). In summary, the FAR is a valuable biomarker associated with STEMI and may be useful in the prediction of the long-term prognosis of patients with STEMI and multivessel disease.

Vascular miR-181b controls tissue factor-dependent thrombogenicity and inflammation in type 2 diabetes. Cardiovasc Diabetol 2020; 19:20. [PMID: 32066445 PMCID: PMC7027062 DOI: 10.1186/s12933-020-0993-z] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 01/26/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Diabetes mellitus is characterized by chronic vascular inflammation leading to pathological expression of the thrombogenic full length (fl) tissue factor (TF) and its isoform alternatively-spliced (as) TF. Blood-borne TF promotes factor (F) Xa generation resulting in a pro-thrombotic state and cardiovascular complications. MicroRNA (miR)s impact gene expression on the post-transcriptional level and contribute to vascular homeostasis. Their distinct role in the control of the diabetes-related procoagulant state remains poorly understood. METHODS In a cohort of patients with poorly controlled type 2 diabetes (n = 46) plasma levels of miR-181b were correlated with TF pathway activity and markers for vascular inflammation. In vitro, human microvascular endothelial cells (HMEC)-1 and human monocytes (THP-1) were transfected with miR-181b or anti-miR-181b and exposed to tumor necrosis factor (TNF) α or lipopolysaccharides (LPS). Expression of TF isoforms, vascular adhesion molecule (VCAM) 1 and nuclear factor (NF) κB nuclear translocation was assessed. Moreover, aortas, spleen, plasma, and bone marrow-derived macrophage (BMDM)s of mice carrying a deletion of the first miR-181b locus were analyzed with respect to TF expression and activity. RESULTS In patients with type 2 diabetes, plasma miR-181b negatively correlated with the procoagulant state as evidenced by TF protein, TF activity, D-dimer levels as well as markers for vascular inflammation. In HMEC-1, miR-181b abrogated TNFα-induced expression of flTF, asTF, and VCAM1. These results were validated using the anti-miR-181b. Mechanistically, we confirmed a miR-181b-mediated inhibition of importin-α3 (KPNA4) leading to reduced nuclear translocation of the TF transcription factor NFκB. In THP-1, miR-181b reduced both TF isoforms and FXa generation in response to LPS due to targeting phosphatase and tensin homolog (PTEN), a principal inducer for TF in monocytes. Moreover, in miR-181-/- animals, we found that reduced levels of miR-181b were accompanied by increased TF, VCAM1, and KPNA4 expression in aortic tissue as well as increased TF and PTEN expression in spleen. Finally, BMDMs of miR-181-/- mice showed increased TF expression and FXa generation upon stimulation with LPS. CONCLUSIONS miR-181b epigenetically controls the procoagulant state in diabetes. Reduced miR-181b levels contribute to increased thrombogenicity and may help to identify individuals at particular risk for thrombosis.

Abstract
Women with prior hypertensive disorders of pregnancy (HDP) are at twice the risk of cardiovascular disease compared with women with prior normotensive pregnancy, possibly because of sustained vascular dysfunction after delivery. The aim of this systematic review and meta-analysis is to summarize evidence of vascular dysfunction at least 3 months after HDP. Articles in all languages were retrieved from principal databases. Studies included were observational, with HDP as the main exposure and measurements of vascular dysfunction via imaging modalities or serum biomarkers as the main outcome, assessed at least 3 months postpartum. We pooled results of modalities reported in >3 studies using a random effects model. Of 6109 potentially relevant studies, 72 were included that evaluated 10 imaging modalities and 11 serum biomarkers in 8702 women. There was evidence of vascular dysfunction in women post HDP compared with women with prior normal pregnancy when measured by carotid-femoral pulse wave velocity (0.64 m/s [0.17–1.11]), carotid intima–media thickness (0.025 mm [0.004–0.045]), and augmentation index (5.48% [1.58–9.37]), as well as mean levels of soluble fms-like tyrosine kinase (6.12 pg/mL [1.91–10.33]). Between-groups differences in measures of vascular dysfunction were more pronounced when assessments were performed in younger women (<40 years) or closer to the index pregnancy for almost all modalities. In conclusion, pooled data from studies evaluating vascular imaging suggest that some vascular dysfunction persists after HDP as compared with women with prior normal pregnancy.

Abstract
Low-grade inflammation is associated with an increased risk of chronic degenerative disease, but its relationship with mortality is less well explored. We aimed at evaluating, at a large epidemiological level, the possible association of low-grade inflammation, as measured by a composite score, with overall mortality risk. We conducted a population-based prospective investigation on 20,337 adult subjects free from major hematological disease and acute inflammatory status, randomly recruited from the general population of the Moli-sani study. A low-grade inflammation score was obtained from the sum of 10-tiles of plasmatic (C-reactive protein) and cellular (leukocyte and platelet counts, granulocyte/lymphocyte ratio) biomarkers of low-grade inflammation; higher levels indicated increased low-grade inflammation. Hazard ratios were calculated using multivariable Cox proportional hazard models with 95% confidence intervals. At the end of follow-up (median 7.6 years), 837 all-cause deaths were recorded. As compared to subjects in the lowest quartile of the low-grade inflammation score, those in the highest category had a significantly increased risk in overall mortality (HR=1.44; 1.17-1.77), independently of possible confounders, including the presence of chronic diseases and a number of health-related behaviors. The magnitude of the association of low-grade inflammation with mortality was relatively higher in type 2 diabetic patients (HR=2.90; 1.74-4.84) and in individuals with a history of cardiovascular disease (HR=2.48; 1.50-4.11) as compared to their counterparts who were free from the disease. In conclusion, an elevated degree of low-grade inflammation, as measured by a composite score of inflammatory biomarkers, is an independent risk factor for total mortality in an apparently healthy adult general population.

Abstract
The prevalence of gestational diabetes mellitus (GDM) in the developed world has increased at an alarming rate over the last few decades. GDM has been shown to be associated with postpartum diabetes, insulin resistance, hypertension, and dyslipidemia. A history of previous GDM (pGDM), associated or not with any of these metabolic abnormalities, can increase the risk of developing not only type 2 diabetes mellitus but also cardiovascular disease (CVD) independent of a diagnosis of type 2 diabetes later in life. In this paper we discuss the relationship among inflammatory markers, metabolic abnormalities, and vascular dysfunction in women with pGDM. We also review the current knowledge on metabolic modifications occurring in normal pregnancy and the link between alterations of a normal metabolic state with the long-term maternal complications that may result in increased CVD risk. Our review of studies on pGDM prompts us to recommend that these women be considered a population at risk for later CVD events, which however could be avoided via the use of specially designed follow-up programs in the future.

Abstract
We evaluated the relationship between admission white blood cell (WBC) count and in-hospital outcomes in acute coronary syndrome (ACS) patients from the Middle East. Data were analyzed from 7806 consecutive patients with ACS who were divided into 4 groups (G) according to their WBC count (× 10(9)/L; G1: < 6.00; G2: 6.00-9.99; G3: 10.00-11.99; G4: ≥ 12.00). After significant covariate adjustment, those in G4 were 68% more likely to have cardiogenic shock than those in G1 (95% confidence interval [CI]: 1.05-2.68; P = .030) and G2 (odds ratio [OR], 2.02; 95% CI: 1.51-2.71; P < .001). Those in G4 were 2.02 times (95% CI: 1.11-3.67; P = .021) and 65% (95% CI: 1.17-2.32; P = .004) more likely to die in hospital than those in G1 and G2, respectively. Admission WBC count is an independent risk factor for in-hospital cardiogenic shock and mortality, in Middle Eastern patients with ACS. Novel therapeutic agents targeting WBCs in patients with ACS may improve outcomes.

Abstract
Inflammatory biomarkers play a pivotal role in atherosclerotic lesions. The plasma levels of these markers are predictive of adverse outcomes such as myocardial infarction and cardiovascular death. The immune system is involved at all stages of atherogenesis via activation of monocytes/macrophages and T lymphocytes. Circulating proinflammatory cytokines and chemokines produced by these cells interact with specific receptors on various cells and activate specific signaling pathways, leading to inflammation-induced atherosclerotic lesions. Recent studies have focused on predictive value of inflammatory biomarkers such as C-reactive protein and interleukin-6. These biomarkers were shown to be associated with poor quality of life and predictive of adverse events in coronary atherosclerosis and left ventricular dysfunction. Vascular predictive value of other numerous inflammatory markers is being investigated. We herein analyze the role of several mediators of inflammation, affecting vascular functions and leading toward atherosclerotic lesions.

Abstract
BACKGROUND Both high-sensitivity C-reactive protein (hs- CRP) and spiral computed tomography coronary artery calcium score (CCS) are valid markers of cardiovascular risk. It is unknown whether hs-CRP is a marker of atherosclerotic burden or if it reflects a process leading to acute coronary events. METHODS AND RESULTS We studied the association between hs- CRP and CCS in 143 patients who were candidates for coronary artery bypass grafting (CABG). In our cross-sectional study, we found no significant association between hs-CRP and the CCS in bivariant (p = 0.162) and multivariant (p = 0.062) analyses. However, in patients who did not use statins, this association was significant and positive in the bivariant analysis (p = 0.001), but in the multivariant analysis it was negative and significant (p = 0.008). CONCLUSION High-sensitivity CRP was not correlated with CCS. The relationship between CRP and clinical events might not be related to atherosclerotic burden. Measures of inflammation, such as hs-CRP, and indices of atherosclerosis, such as CCS, are likely to provide distinct information regarding cardiovascular risk.

Abstract
Background: Coronary artery disease (CAD) is a major public health problem which in turn imposes a significant burden on health care systems because of high morbidity and mortality. Although the multifactorial etiology of CAD increases with age, but in recent years, the incidence is increasing among younger age groups. Objectives: In this study we aimed to evaluate the effect of age on risk profile, inflammatory response and the angiographic findings in patients with ACS. Patients and Methods: The study comprised 253 ACS patients. Seventy six (30%) with UA, 56 (22%) with NSTEMI and 121(48%) with STEMI diagnosis. The value of Hs-CRP, lipid profile, cardiac enzymes, risk factors, EF% and angiographic score were analyzed and compared in different age groups. Results: Group 1 (n = 68) with age <45 years, group II (n = 110) with age ≥45–<65 years and group III (n = 75) ≥65 years. Group I had more prevalence of male sex, smoking, family history, hypertriglyceridemia and low levels of HDL (P < 0.01), higher incidence of STEMI (P < 0.01) and lower prevalence of UA (P < 0.01). Diabetes mellitus, hypertension, and female gender were more common in older groups. Hs-CRP was significantly lower in the young age (group I). Group I showed a preponderance of single-vessel disease, lower coronary atherosclerotic score and prevalent left anterior descending artery (LAD) involvement compared with older age groups. Hs-CRP was positively correlated to severity of CAD only in older groups. Stepwise multiple regression analysis showed that age, male gender, cardiac enzymes and EF% were common predictors of multivessel disease. Smoking was independent predictor in young patients <45 years while diabetes and Hs-CRP was the key predictor in older patient groups. Conclusion: Young patients with ACS had different clinical, angiographic and biochemical profile. Hs-CRP peak concentration did not correlate with angiographic findings in young patients that could be attributed to different risk profile and discrete underlying mechanism.

Abstract
There is increasing evidence that systemic inflammation plays an important role in the pathogenesis of COPD. Inflammatory markers show relationships with exercise performance, health related quality of life and breathlessness. These are important clinical outcomes in the management of COPD. Even more so is the consideration that systemic inflammation in COPD may be directly associated with mortality and deterioration of disease. Long-term exercise training clearly has beneficial properties in healthy subjects, whether the same is true in COPD remains to be seen. This review discusses aspects of the anti-inflammatory effects of exercise in relation to patients with COPD. There is intriguing evidence that the exercise-induced cytokine response differs in COPD patients compared with healthy subjects. We consider the role of IL-6 in the manifestation of fatigue in COPD and consider the implications of raised CRP- and TNF-alpha. Early data suggests beneficial effects of polyunsaturated fatty acid PUFA supplementation and exercise training in combination with appropriate nutritional support may yield rewarding therapeutic benefits. This review raises the hypothesis that physical training in COPD is associated with immunological changes that may confer anti-inflammatory benefits and in part, explain changes seen after pulmonary rehabilitation in COPD patients.

Abstract
Non-ST segment elevation acute coronary syndromes (NSTE ACS) include a clinical spectrum that ranges from unstable angina to NSTE myocardial infarction. Management goals aim to prevent recurrent ACS and improve long-term outcomes by choosing a treatment strategy according to an estimate of the risk of an adverse outcome. Recent registry data suggest that patients with NSTE ACS frequently do not receive recommended treatment, and that risk stratification is not used to determine either the choice of treatment or the speed of access to coronary angiography. The present article evaluates the evidence for recommended treatment using information from recent trials and guidelines published by the major cardiac organizations in Europe and North America. Using this information, a multidisciplinary group developed a simplified algorithm that uses risk stratification to select an optimal early management strategy. Long-term outcomes are improved by a multi-faceted vascular protection strategy that is initiated at the time of hospitalization for NSTE ACS.

Abstract
OBJECTIVE To investigate in a follow-up study whether high-sensitivity C-reactive protein (hs-CRP) predicts coronary heart disease (CHD) events in subjects with type 2 diabetes. RESEARCH DESIGN AND METHODS The original study population consisted of 1,059 patients with type 2 diabetes (age 45-64 years). Mean duration of diabetes was 8 years. CRP values were available from 1,045 subjects, of whom 878 were free of myocardial infarction (MI) at baseline. CHD mortality and the incidence of nonfatal MI were assessed in a 7-year follow-up. RESULTS Altogether, 157 patients died from CHD and 254 had a nonfatal or fatal CHD event. Patients with hs-CRP >3 mg/l had a higher risk for CHD death than patients with hs-CRP < or =3 mg/l (19.8 and 12.9%, respectively, P = 0.004). In Cox regression analysis, patients with high hs-CRP had a relative risk of 1.72 for CHD death even after the adjustment for confounding factors (P = 0.002). Among subjects who were free from MI at baseline, those with a high hs-CRP level had relative risks of 1.83 (P = 0.003) and 1.84 (P = 0.004) for CHD death in univariate and multivariate analyses, respectively. CONCLUSIONS In this large cohort of type 2 diabetic patients, hs-CRP was an independent risk factor for CHD deaths.

Abstract
C-reactive protein (CRP) is a marker of inflammation and predicts outcome in apparently healthy subjects and patients with coronary artery disease. Systemic inflammation is present in patients with aortic valve stenosis (AS). The aim of this prospective study was to assess whether CRP levels predict the progression of AS severity. Blood samples for high-sensitivity CRP measurements and echocardiographic data were obtained in 43 patients (70% men; mean age 73 +/- 8 years) with asymptomatic degenerative AS at study entry. On the basis of repeat echocardiographic assessment at 6 months, patients were grouped as (1) slow progressors (a decrease in aortic valve area [AVA] <0.05 cm2 and/or an increase in aortic peak velocity <0.15 m/s) and (2) rapid progressors (a decrease in AVA > or =0.05 cm2 and/or an increase in aortic peak velocity > or =0.15 m/s). Plasma CRP levels were significantly higher in rapid progressors than slow progressors (median 5.1 [range 2.3 to 11.3] vs 2.1 [range 1.0 to 3.1] mg/L, p = 0.007). In multivariate analysis, CRP levels >3 mg/L were independently associated with rapid AS progression (odds ratio 9.1, 95% confidence interval 2.2 to 37.3). In conclusion, CRP levels are higher in patients with degenerative AS who show rapid valve disease progression. These findings suggest that inflammation may have a pathogenic role in degenerative AS.

Abstract
The prevention, treatment and management of disease are closely linked to how the causes of a particular disease are explained. For multi-factorial conditions, the causal explanations are inevitably complex and competing models may exist to explain the same condition. Selecting one particular causal explanation over another will carry practical and ethical consequences that are acutely relevant for health policy. In this paper our focus is two-fold; (i) the different models of causal explanation that are put forward within current scientific literature for the high and rising prevalence of the common complex conditions of coronary artery disease (CAD) and type 2 diabetes mellitus (T2D); and (ii) how these explanations are taken up (or not) within national health policy guidelines. We examine the causal explanations for these two conditions through a systematic database search of current scientific literature. By identifying different causal explanations we propose a three-tier taxonomy of the most prominent models of explanations: (i) evolutionary, (ii) lifecourse, and (iii) lifestyle and environment. We elaborate this taxonomy with a micro-level thematic analysis to illustrate how some explanations are semantically and rhetorically foregrounded over others. We then investigate the uptake of the scientific causal explanations in health policy documents with regard to the prevention and management recommendations of current National Service Frameworks for CAD and T2D. Our findings indicate a lack of congruence between the complexity and frequent overlap of causal explanations evident in the scientific literature and the predominant focus on lifestyle recommendations found in the mainstream health policy documents.

Abstract
The formation of a fibrin clot is one of the key events in atherothrombotic vascular diseases, such as myocardial infarction, ischemic stroke and peripheral arterial disease. Fibrin is formed from a circulating precursor, fibrinogen, by the action of thrombin. Both genetic and environmental factors are important determinants of the circulating fibrinogen levels. Epidemiologic studies have demonstrated a role for this hemostatic protein in the prediction of cardiovascular disease. As an acute-phase reactant, fibrinogen is also a marker of inflammation. Likewise, recent studies from our group have shown that increased fibrinogen levels represent a marker of subclinical atherosclerosis, likely to be useful in the identification of asymptomatic subjects at risk for cardiovascular disease.

Abstract
OBJECTIVES Short-term randomised trials suggest that patients with diabetes mellitus (DM), admitted with acute coronary syndromes (ACS) are at increased risk of subsequent adverse events. We tested whether this hypothesis was true for an unselected population of ACS patients with and without DM admitted with non-ST elevation MI or unstable angina, in a non-trial setting over a longer term of follow-up. METHODS Prospective, centrally, coordinated multicenter registry involving 56 centers throughout the UK (half having angiographic facilities). Consecutive patients admitted with ACS without ST elevation on the presenting ECG were followed up to 6 months. A sub-group of patients were flagged with the UK Office for National Statistics and followed-up for death over 4 years. RESULTS Data were collected on 1046 ACS patients of whom 170 (16%) had a prior diagnosis of DM. DM patients had higher baseline co-morbidities and unadjusted mortality rates at 6 months (11.8% vs. 6.4%, p=0.01). After correcting for clinical variables such as age, gender, smoking status and chest pain/ischaemic ECG changes on admission, prior history of any of myocardial infarction, heart failure, hypertension, hypercholesterolemia (on treatment), stroke or coronary revascularisation (PTCA or CABG), mortality rates for DM patients were no longer significantly raised (hazard ratio 1.35, 95% CI: 0.79-2.30; p=0.27 at 6 months and 1.15, 95% CI 0.72-1.83 at 4 years). 30% of diabetics were dead after 4 years of follow-up. Patients with DM were more likely to have been revascularised at 6 months and were more likely to receive ACE inhibitors. Based on the rate of recruitment and the population covered in the study, about 21,000 patients with DM will be admitted with non-ST elevation ACS each year in the UK. CONCLUSIONS DM is common amongst patients admitted with ACS without ST elevation and is associated with significant morbidity and mortality: approximately 1 in 8 will not survive up to 6 months and 1 in 3 to 4 years. DM patients should be managed aggressively to reduce their risk of future complications.
