Experimentally Induced Peripheral Venous Congestion Exacerbates Inflammation, Oxidative Stress, and Neurohormonal and Endothelial Cell Activation in Patients With Systolic Heart Failure. J Card Fail 2024; 30:580-591. [PMID: 37625581 PMCID: PMC10884348 DOI: 10.1016/j.cardfail.2023.07.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/28/2023] [Accepted: 07/28/2023] [Indexed: 08/27/2023]
Abstract
BACKGROUND Venous congestion (VC) is a hallmark of symptomatic heart failure (HF) requiring hospitalization; however, its role in the pathogenesis of HF progression remains unclear. We investigated whether peripheral VC exacerbates inflammation, oxidative stress and neurohormonal and endothelial cell (EC) activation in patients with HF with reduced ejection fraction (HFrEF). METHODS AND RESULTS Two matched groups of patients with HFrEF and with no peripheral VC vs without recent HF hospitalization were studied. We modeled peripheral VC by inflating a cuff around the dominant arm, targeting ∼ 30 mmHg increase in venous pressure (venous stress test [VST]). Blood and ECs were sampled before and after 90 minutes of VST. We studied 44 patients (age 53 ± 12 years, 32% female). Circulating endothelin-1, tumor necrosis factor-α, interleukin-6, isoprostane, angiotensin II (ang-2), angiopoietin-2, vascular cell adhesion molecule-1, and CD146 significantly increased after the VST. Enhanced endothelin-1 and angiopoietin-2 responses to the VST were present in patients with vs without recent hospitalization and were prospectively associated with incident HF-related events; 6698 messenger ribonucleic acid (mRNA probe sets were differentially expressed in ECs after VST. CONCLUSIONS Experimental VC exacerbates inflammation, oxidative stress, neurohormonal and EC activation and promotes unfavorable transcriptome remodeling in ECs of patients with HFrEF. A distinct biological sensitivity to VC appears to be associated with high risk for HF progression.

ESC Heart Fail 2021; 8:2328-2333. [PMID: 33694306 PMCID: PMC8120355 DOI: 10.1002/ehf2.13280] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 01/28/2021] [Accepted: 02/11/2021] [Indexed: 12/30/2022] Open
Abstract
Aims The aim of the study was to assess the association of P‐selectin with outcomes in heart failure with preserved ejection fraction (HFpEF). Methods and results This is a prospective, observational study of 130 HFpEF patients who underwent clinical profiling, blood sampling, 6 min walk testing, Minnesota Living with Heart Failure Questionnaire evaluation, echocardiography, cardiovascular magnetic resonance imaging, calculation of the Meta‐Analysis Global Group in Chronic Heart Failure (MAGGIC) risk scores, and blinded plasma P‐selectin measurement. Patients were followed up for the endpoint of all‐cause mortality. The HFpEF subgroup with higher P‐selectin levels [overall median 26 372, inter‐quartile range (19 360–34 889) pg/mL] was associated with lower age, higher heart rate, less prevalent atrial fibrillation, more frequent current smoking status, and lower right ventricular end‐diastolic volumes. During follow‐up (median 1428 days), there were 38 deaths. Following maximal sensitivity and specificity receiver operating characteristic curve analysis, P‐selectin levels above 35 506 pg/mL were associated with greater risk of all‐cause mortality [hazard ratio (HR) 2.700; 95% confidence interval (CI) 1.416–5.146; log‐rank P = 0.002]. Following multivariable Cox proportional hazards regression analysis and when added to MAGGIC scores, only P‐selectin (adjusted HR 1.707; 95% CI 1.099–2.650; P < 0.017) and myocardial infarction detected by cardiovascular magnetic resonance imaging (HR 2.377; 95% CI 1.114–5.075; P < 0.025) remained significant predictors. In a final model comprising all three parameters, only P‐selectin (HR 1.447; 95% CI 1.130–1.853; P < 0.003) and MAGGIC scores (HR 1.555; 95% CI 1.136–2.129; P < 0.006) remained independent predictors of death. Adding P‐selectin (0.618, P = 0.035) improved the area under the receiver operating characteristic curve for mortality prediction for MAGGIC scores (0.647, P = 0.009) to 0.710, P < 0.0001. Conclusions Plasma P‐selectin is an independent predictor of mortality and provides incremental prognostic information beyond MAGGIC scores in HFpEF.

Up-regulation of miR-27 extenuates lipopolysaccharide-induced injury in H9c2 cells via modulating ICAM1 expression. Genes Genomics 2019; 41:1467-1474. [PMID: 31576518 DOI: 10.1007/s13258-019-00863-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Accepted: 08/25/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND MiR-27 has been found to present an overt myocardial expression during cardiogenesis. However, whether miR-27 involves in myocarditis development and the possible molecular mechanism remain unknown. The purpose of this study was to investigate the biological characteristic of miR-27 in LPS-damaged H9c2 cells. METHODS H9c2 cells were treated with lipopolysaccharide (LPS, 10 µg/ml) for 12 h to form cell injury. MiR-27 mimic and inhibitor were used to up-regulate or down-regulate miR-27 expression. MTT assay and flow cytometry analysis were conducted to test cell viability and apoptosis. The relative RNA expression level of miR-27 and intercellular adhesion molecule 1 (ICAM1) was determined by qRT-PCR. Luciferase reporter gene assay was utilized to confirm the interaction between miR-27 and ICAM1. Western blot was used to determine the protein expression levels. RESULTS We observed that LPS treatment significantly decreased the level of miR-27 in H9c2 cells. Moreover, LPS exposure suppressed cell viability, promoted cell apoptosis and increased the relative expression of p-NF-κB p65/NF-κB p65 and p-IκBα/IκBα. Up-regulation of miR-27 increased cell proliferation and reduced cell apoptosis, while down-regulation of miR-27 suppressed cell growth and promoted cell apoptosis. ICAM1 was predicted and verified as a target of miR-27, and the expression of ICAM1 is negatively regulated by miR-27. The relative expression of p-NF-κB p65/NF-κB p65 and p-IκBα/IκBα was dramatically decreased by miR-27 mimic and increased by miR-27 inhibitor. CONCLUSION Our study illustrated that up-regulation of miR-27 exhibits a protective effect on LPS-damaged H9c2 cells, which may be achieved by regulating ICAM1 and NF-κB signaling.

Abstract
Heart failure (HF) is associated in humans and mice with increased circulating levels of CXCL9 and CXCL10, chemokine ligands of the CXCR3 receptor, predominantly expressed on CD4+ Th1 cells. Chemokine engagement of receptors is required for T cell integrin activation and recruitment to sites of inflammation. Th1 cells drive adverse cardiac remodeling in pressure overload-induced cardiac dysfunction, and mice lacking the integrin ligand ICAM-1 show defective T cell recruitment to the heart. Here, we show that CXCR3+ T cells infiltrate the heart in humans and mice with pressure overload-induced cardiac dysfunction. Genetic deletion of CXCR3 disrupts CD4+ T cell heart infiltration and prevents adverse cardiac remodeling. We demonstrate that cardiac fibroblasts and cardiac myeloid cells that include resident and infiltrated macrophages are the source of CXCL9 and CXCL10, which mechanistically promote Th1 cell adhesion to ICAM-1 under shear conditions in a CXCR3-dependent manner. To our knowledge, our findings identify a previously unrecognized role for CXCR3 in Th1 cell recruitment into the heart in pressure overload-induced cardiac dysfunction.

Abstract
Elevated levels of pro-inflammatory markers are evident in patients with heart failure and are associated with disease severity and prognosis. Exercise training has been shown to reduce circulating levels of pro-inflammatory cytokines and other pro-inflammatory markers in healthy and clinical populations. The aim of the systematic review and meta-analysis was to investigate the effect of aerobic (AT) and resistance training (RT) interventions on circulating concentrations of inflammatory markers; tumour necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), C-reactive protein (CRP), fibrinogen, soluble intercellular adhesion molecule (sICAM) and soluble vascular adhesion molecule (sVCAM) in heart failure patients. We conducted database searches (PubMed, EMBASE and Cochrane Trials Register to 30 June 2017) for exercise-based trials in heart failure, using the following search terms: exercise training, inflammation, tumour necrosis factor-alpha, interleukin 6, C-reactive protein, fibrinogen, soluble intercellular adhesions molecule-1, soluble vascular adhesion molecule-1. Twenty studies, representing 18 independent trials, were included in the review. Pooled data of six studies indicated a minimally favourable effect of exercise training on circulating TNF-α [SMD 0.42 (95% CI 0.15, 0.68), p = 0.002)]. However, together the pooled and descriptive analyses failed to provide strong evidence for a reduction in other pro-inflammatory markers. However, given the complexity of heart failure and the pathways involved in the immune and inflammatory process, large prospective trials considering aetiology, comorbidities and local skeletal muscle inflammation are required to elucidate on the anti-inflammatory effect of exercise in this population.

Abstract
OBJECTIVE Previous studies have suggested that cytokines and growth factors may predict ventricular recovery following aortic valve replacement (AVR). The primary objective of this study was to identify cytokines that predict ventricular recovery following transcatheter AVR (TAVR). METHODS We prospectively enrolled 121 consecutive patients who underwent TAVR. Standard echocardiographic assessment at baseline, 1-month and 1-year after TAVR included left ventricular (LV) mass index (LVMI) and global longitudinal strain (GLS). Blood samples were obtained at the time of the procedure to measure cytokines using a 63-plex Luminex platform. Partial least squares-discriminant analysis was performed to identify cytokines associated with ventricular remodeling and function at baseline as well as 1 year after TAVR. RESULTS The mean age was 84 ± 9 years, with a majority of male subjects (59%), a mean LVMI of 120.4 ± 45.1 g/m2 and LVGLS of -13.0 ± 3.2%. On average, LV mass decreased by 8.1% and GLS improved by 20.3% at 1 year following TAVR. Among cytokines assayed, elevated hepatocyte growth factor (HGF) emerged as a common factor significantly associated with worse baseline LVMI and GLS as well as reduced ventricular recovery (p < 0.005). Other factors associated with ventricular recovery included a select group of vascular growth factors, inflammatory mediators and tumor necrosis factors, including VEGF-D, ICAM-1, TNFβ, and IL1β. CONCLUSION We identified a network of cytokines, including HGF, that are significantly correlated with baseline LVMI and GLS, and ventricular recovery following TAVR.

Abstract
BACKGROUND We have a limited understanding of the biological underpinnings of symptoms in heart failure (HF). OBJECTIVES The purpose of this paper was to compare relationships between peripheral biomarkers of HF pathogenesis and physical symptoms between patients with advanced versus moderate HF. METHODS This was a two-stage phenotype sampling cohort study wherein we examined patients with advanced HF undergoing ventricular assist device implantation in the first stage, and then patients with moderate HF (matched adults with HF not requiring device implantation) in the second stage. Linear modeling was used to compare relationships among biomarkers and physical symptoms between cohorts. RESULTS Worse myocardial stress, systemic inflammation and endothelial dysfunction were associated with worse physical symptoms in moderate HF (n=48), but less physical symptom burden in advanced HF (n=48). CONCLUSIONS Where patients are in the HF trajectory needs to be taken into consideration when exploring biological underpinnings of physical HF symptoms.

Abstract
SummaryThe objective of this study was to evaluate the expression of cell adhesion molecule (CAM) receptors (integrins) on monocyte subsets in heart failure (HF) and examine their prognostic implication. Increased levels of soluble CAMs have been observed in patients with HF, but the precise mechanism of monocyte adhesion to the vascular endothelium remains unknown. Patients with acute HF (AHF, n=51) were compared to those with stable HF (SHF, n=42) and stable coronary artery disease (CAD, n=44) without HF. Expression of integrins-receptors to intercellular adhesion molecule-1 (ICAM-1R) and vascular CAM-1 (VCAM-1R) on monocyte subsets was assessed by flow cytometry. Monocyte subsets were defined as CD14++CD16–CCR2+ (‘classical’, Mon1), CD14++CD16+CCR2+ (‘intermediate’, Mon2), and CD14+CD16++CCR2– (‘non-classical’, Mon3). Compared to patients with SHF, those with AHF had significantly higher expression of ICAM-1R on Mon2 (p=0.01). Compared to those with stable CAD, patients with SHF had a significantly higher expression of ICAM-1R on Mon2 (p=0.025). Compared to SHF, patients with AHF had a similar expression of VCAM-1R on both Mon1 and Mon3 but significantly higher expression on Mon2 (p=0.019). There were no significant differences between SHF and CAD in monocyte expression of VCAM-1R. In multivariate Cox regression analysis, VCAM-1R expression on Mon2 was associated with adverse clinical outcome (death or rehospitalisation) in AHF [HR 1.07 (1.01–1.14), p=0.029]. In conclusion, HF is associated with increased monocyte expression of integrins-receptors to both ICAM-1 and VCAM-1, being particularly linked to Mon2 subset. Expression of VCAM-1R on Mon2 may have prognostic value in patients with AHF.

Abstract
BACKGROUND Previous studies have shown beneficial effects of functional electrical stimulation (FES) on muscle performance and exercise capacity of patients with chronic heart failure. This study evaluates the impact of FES on endothelial function and peripheral markers of immune activation in patients with moderate to severe heart failure. METHODS Twenty-four patients with a left ventricular ejection fraction of less than 40% and New York Heart Association class II-III symptoms, undergoing optimized drug therapy, were randomly assigned (2 : 1) to a 6-week training programme of FES (n=16) or served as controls (n=8). Endothelial function was assessed by Doppler flow-mediated dilatation (FMD) of the brachial artery before and after the training programme. Peripheral pro-inflammatory/anti-inflammatory markers such as tumour necrosis factor (TNF)-alpha, interleukin (IL)-6, soluble intercellular adhesion molecule (sICAM)-1, soluble vascular cell adhesion molecule (sVCAM)-1 and IL-10 were also measured before and after training. RESULTS A significant improvement on the 6-min walk test (7.5+/-3.3%), Minnesota Living Score (18.2+/-8.6%) and FMD (38.5+/-15.1%) was observed only in the FES-treated group. FES also causes a significant reduction of TNF-alpha (-11.5+/-8.9%), sICAM-1 (-13.1+/-9.8%), and sVCAM-1 (-10.6+/-6.6%), as well as a respective increase in the ratio IL-10/TNF-alpha (37.1+/-29.4%). In the FES group, the percentage improvement in the Minnesota Living Score was significantly correlated with respective changes in circulating TNF-alpha (r=0.624, P<0.01), sVCAM-1 (r=0.665, P<0.001) and the ratio IL-10/TNF-alpha (r=-0.641, P<0.01). CONCLUSION FES is an exercise training programme that improves endothelial function in patients with chronic heart failure, and also has anti-inflammatory effects.

Abstract
The peripheral blood mononuclear cell (PBMC) count is a routinely used and meaningful index for infection and blood diseases. PBMCs may be closely related to osteoclasts and include osteoclast precursors; we examined the association between the PBMC count and bone health. This research included 2806 community men aged ≥50 years who underwent full health examinations from October 2007 through December 2011 in four medical centers. The PBMC count was significantly high among subjects with "at least osteopenia" compared with controls. In analysis of covariance adjusted for potential confounders, the bone mineral density (BMD) value and T-score had a significant decreasing trend across the quartiles of PBMC count. In univariate analysis, the PBMC count had a strong association with "at least osteopenia" (odds ratio [OR] = 2.520, 95% confidence interval [CI]: 1.397-4.547). After adjustment for confounding factors (multivariate analysis) from Model 1 to 4, PBMC count remained as an independent risk factor for "at least osteopenia" (OR = 2.481, 95% CI: 1.176-5.236). Moreover, after adjusting for all confounding variables, participants had a significantly high OR in the body mass index (BMI) <25 group (OR = 2.798, CI: 1.122-6.973; P = 0.027) and systolic blood pressure (SBP) <140 group (OR = 2.519, CI: 1.059-5.993; P = 0.037). In conclusion, the PBMC count is significantly associated with bone loss in elderly men and the exact mechanism requires further clarification.

Abstract
Background Left ventricular dysfunction and heart failure are strongly associated in humans with increased circulating levels of proinflammatory cytokines, T cells, and soluble intercellular cell adhesion molecule 1 (ICAM1). In mice, infiltration of T cells into the left ventricle contributes to pathological cardiac remodeling, but the mechanisms regulating their recruitment to the heart are unclear. We hypothesized that ICAM1 regulates cardiac inflammation and pathological cardiac remodeling by mediating left ventricular T‐cell recruitment and thus contributing to cardiac dysfunction and heart failure. Methods and Results In a mouse model of pressure overload–induced heart failure, intramyocardial endothelial ICAM1 increased within 48 hours in response to thoracic aortic constriction and remained upregulated as heart failure progressed. ICAM1‐deficient mice had decreased T‐cell and proinflammatory monocyte infiltration in the left ventricle in response to thoracic aortic constriction, despite having numbers of circulating T cells and activated T cells in the heart‐draining lymph nodes that were similar to those of wild‐type mice. ICAM1‐deficient mice did not develop cardiac fibrosis or systolic and diastolic dysfunction in response to thoracic aortic constriction. Exploration of the mechanisms regulating ICAM1 expression revealed that endothelial ICAM1 upregulation and T‐cell infiltration were not mediated by endothelial mineralocorticoid receptor signaling, as demonstrated in thoracic aortic constriction studies in mice with endothelial mineralocorticoid receptor deficiency, but rather were induced by the cardiac cytokines interleukin 1β and 6. Conclusions ICAM1 regulates pathological cardiac remodeling by mediating proinflammatory leukocyte infiltration in the left ventricle and cardiac fibrosis and dysfunction and thus represents a novel target for treatment of heart failure.

Abstract
Venous congestion and endothelial and neurohormonal activation are known to occur in acute decompensated heart failure (ADHF), yet the temporal role of these processes in the pathophysiology of decompensation is not fully understood. Conventional wisdom presumes congestion to be a consequence of worsening cardiovascular function; however, the biomechanically driven effects of venous congestion are biologically plausible contributors to ADHF that remain largely unexplored in vivo. Recent experimental evidence from human models suggests that fluid accumulation and venous congestion are not simply consequences of poor cardiovascular function, but rather are fundamental pro-oxidant, pro-inflammatory, and hemodynamic stimuli that contribute to acute decompensation. The latest advances in the monitoring of volume status using implantable devices allow for the detection of venous congestion before symptoms arise. This may ultimately lead to improved treatment strategies including not only diuretics, but also specific, adjuvant interventions to counteract endothelial and neurohormonal activation during early preclinical decompensation.

Abstract
BACKGROUND Studies suggest that thrombocytopaenia is associated with a higher mortality in several diseases. Little is known about the effect of low platelet count on mortality in patients with heart failure with reduced ejection fraction (HFrEF). The aim of this study was to determine the prognostic value of thrombocytopaenia in these patients by assessing all-cause mortality. METHODS A total of 1,907 patients with HFrEF, defined by left ventricular ejection fraction <40% on echocardiography, were analysed in this multi-centre retrospective study. All patients were on medical therapy with a beta-blocker and an angiotensin-converting enzyme inhibitor. Patients were categorised into two groups based on platelet count measured within one month of the diagnosis of HFrEF: normal to mild thrombocytopaenia (platelet count 100,000-450,000 per uL); and moderate to severe thrombocytopaenia (platelet count <100,000 per uL). One-year all-cause mortality was compared between the two groups. RESULTS Mean age was 65±15 years and 62% of patients were male. Overall one-year mortality was 17.2% with higher mortality among patients with HFrEF and moderate/severe thrombocytopaenia compared to those with normal/mild thrombocytopaenia (33.0% vs. 15.4%, p <0.001). After adjusting for baseline characteristics, patients with HFrEF and moderate/severe thrombocytopaenia had a higher mortality compared to patients with normal/mild thrombocytopaenia (HR 1.84, 95% CI 1.33-2.56, p <0.001). CONCLUSION In patients with HFrEF, higher degree of thrombocytopaenia is associated with higher all-cause mortality. These findings may support the use of platelet counts as a prognostic marker in the assessment of the patient with HFrEF.

Abstract
Heart failure (HF) is an increasingly prevalent and costly multifactorial syndrome with high morbidity and mortality rates. The exact pathophysiological mechanisms leading to the development of HF are not completely understood. Several emerging paradigms implicate cardiometabolic risk factors, inflammation, endothelial dysfunction, myocardial fibrosis, and myocyte dysfunction as key factors in the gradual progression from a healthy state to HF. Inflammation is now a recognized factor in disease progression in HF and a therapeutic target. Furthermore, the monocyte-platelet interaction has been highlighted as an important pathophysiological link between inflammation, thrombosis, endothelial activation, and myocardial malfunction. The contribution of monocytes and platelets to acute cardiovascular injury and acute HF is well established. However, their role and interaction in the pathogenesis of chronic HF are not well understood. In particular, the cross talk between monocytes and platelets in the peripheral circulation and in the vicinity of the vascular wall in the form of monocyte-platelet complexes (MPCs) may be a crucial element, which influences the pathophysiology and progression of chronic heart disease and HF. In this review, we discuss the role of monocytes and platelets as key mediators of cardiovascular inflammation in HF, the mechanisms of cell activation, and the importance of monocyte-platelet interaction and complexes in HF pathogenesis. Finally, we summarize recent information on pharmacological inhibition of inflammation and studies of antithrombotic strategies in the setting of HF that can inform opportunities for future work. We discuss recent data on monocyte-platelet interactions and the potential benefits of therapy directed at MPCs, particularly in the setting of HF with preserved ejection fraction.

Abstract
BACKGROUND Unexplained heterogeneity in response to ventricular assist device (VAD) implantation for the management of advanced heart failure impedes our ability to predict favorable outcomes, provide adequate patient and family education, and personalize monitoring and symptom management strategies. The purpose of this article was to describe the background and the design of a study entitled "Profiling Biobehavioral Responses to Mechanical Support in Advanced Heart Failure" (PREMISE). STUDY DESIGN AND METHODS PREMISE is a prospective cohort study designed to (1) identify common and distinct trajectories of change in physical and psychological symptom burden; (2) characterize common trajectories of change in serum biomarkers of myocardial stress, systemic inflammation, and endothelial dysfunction; and (3) quantify associations between symptoms and biomarkers of pathogenesis in adults undergoing VAD implantation. Latent growth mixture modeling, including parallel process and cross-classification modeling, will be used to address the study aims and will entail identifying trajectories, quantifying associations between trajectories and both clinical and quality-of-life outcomes, and identifying predictors of favorable symptom and biomarker responses to VAD implantation. CONCLUSIONS Research findings from the PREMISE study will be used to enhance shared patient and provider decision making and to shape a much-needed new breed of interventions and clinical management strategies that are tailored to differential symptom and pathogenic responses to VAD implantation.

Abstract
Dilated cardiomyopathy (DCM) is one of the leading causes of mortality; however, the underlying molecular mechanisms of DCM remain to be elucidated. H3K9 histone methyltransferase G9a has been previously characterized, although its functions in DCM are not yet understood. Cell adhesion molecules (CAM) are highly expressed in diseased human hearts and were thought to contribute to chronic degeneration in cardiac incompetence; however, it has been suggested that G9a may suppress the effects of CAM. The aim of the present study was to investigate whether G9a decreased the risk of DCM via regulation of CAM expression. A rat model of DCM was induced using furazolidone (FZ) treatment and numerous parameters were examined. G9a RNA interference (RNAi) was applied to primary neonatal cardiomyocytes (PNCs). Reverse transcription quantitative polymerase chain reaction and western blot analyses were used to examine the expression levels of G9a in the DCM model and PNCs. The growth rate of PNCs was evaluated following G9a RNAi and FZ treatment. The results confirmed that the expression levels of G9a were significantly decreased in the DCM model compared with those in the control group (P<0.01). Conversely, CAM expression levels were significantly increased in the DCM model compared with those in the control group (P<0.01). In PNCs, the expression of CAM was upregulated following G9a silencing using RNAi. Following three‑day culture, the growth rate of PNCs was inhibited by 70 and 35% following FZ treatment and G9a RNAi, respectively. In conclusion, G9a ameliorated DCM via downregulation of CAMs, therefore indicating its potential for use in the treatment of DCM.

Abstract
Background Soluble vascular cell adhesion molecule-1 (sVCAM-1) is a marker of endothelial injury and a potent predictor of cardiovascular mortality in patients with kidney failure on dialysis. The longitudinal effects of dialysis on endothelial dysfunction and in particular the effects of renal transplantation on markers of endothelial function including sVCAM-1 have not been well characterized. Methods We used the Transplant Manitoba registry and biobank to assemble a retrospective cohort of all patients receiving a first kidney transplant between January 1, 2000, and December 31, 2005 (n=186). One hundred seventy-four patients had at least two serum samples pretransplant and at least two samples posttransplant. In total, 1,004 serial samples (median 5/patient) were analyzed. Factors associated with sVCAM-1 were examined using mixed linear models. Results The sVCAM-1 levels increased progressively on dialysis (0.15 [0.10 to 0.20] ng/mL/day; P<0.0001), fell significantly within 1 month after transplantation (−625 ng/mL/day; P<0.0001) and continued to fall thereafter (−0.23 [−0.34 to −0.12] ng/mL/day). Smoking and heart failure were associated with higher sVCAM-1 levels, whereas transplantation was associated with lower sVCAM-1 levels. The relationship between sVCAM-1 and transplantation was not changed by multivariate adjustment. Conclusion Endothelial injury worsens over time on dialysis but improves significantly after renal transplantation. Supplemental digital content is available in the article.

Abstract
AIMS Volume overload and venous congestion are typically viewed as a consequence of advanced and of acute heart failure (HF) and renal failure (RF) although it is possible that hypervolaemia itself might be a critical intermediate in the pathophysiology of these diseases. This study aimed at elucidating whether peripheral venous congestion is sufficient to promote changes in inflammatory, neurohormonal, and endothelial phenotype similar to those observed in HF and RF. METHODS To experimentally model peripheral venous congestion, we developed a new method (so-called venous stress test) and applied the methodology on 24 healthy subjects (14 men, age 35 ± 2 years). Venous arm pressure was increased to ∼30 mmHg above the baseline level by inflating a tourniquet cuff around the dominant arm (test arm). Blood and endothelial cells (ECs) were sampled from test and control arm (lacking an inflated cuff) before and after 75 min of venous congestion, using angiocatheters and endovascular wires. Magnetic beads coated with EC-specific antibodies were used for EC separation; amplified mRNA was analysed by Affymetrix HG-U133 Plus 2.0 Microarray. RESULTS Plasma interleukin-6 (IL-6), endothelin-1 (ET-1), angiotensin II (AII), vascular cell adhesion molecule-1 (VCAM-1), and chemokine (C-X-C motif) ligand 2 (CXCL2) were significantly increased in the congested arm. A total of 3437 mRNA probe sets were differentially expressed (P < 0.05) in venous ECs before vs. after testing, including ET-1, VCAM-1, and CXCL2. CONCLUSION Peripheral venous congestion causes release of inflammatory mediators, neurohormones, and activation of ECs. Overall, venous congestion mimicked, notable aspects of the phenotype typical of advanced and of acute HF and RF.

Abstract
Although inflammation is a physiologic response designed to protect us from infection, when unchecked and ongoing it may cause substantial harm. Both chronic heart failure (CHF) and chronic kidney disease (CKD) are known to cause elaboration of several pro-inflammatory mediators that can be detected at high concentrations in the tissues and blood stream. The biologic sources driving this chronic inflammatory state in CHF and CKD are not fully established. Traditional sources of inflammation include the heart and the kidneys which produce a wide range of pro-inflammatory cytokines in response to neurohormones and sympathetic activation. However, growing evidence suggests that non-traditional biomechanical mechanisms such as venous and tissue congestion due to volume overload are also important as they stimulate endotoxin absorption from the bowel and peripheral synthesis and release of pro-inflammatory mediators. Both during the chronic phase and, more rapidly, during acute exacerbations of CHF and CKD, inflammation and congestion appear to amplify each other resulting in a downward spiral of worsening cardiac, vascular, and renal functions that may negatively impact patients' outcome. Anti-inflammatory treatment strategies aimed at attenuating end organ damage and improving clinical prognosis in the cardiorenal syndrome have been disappointing to date. A new therapeutic paradigm may be needed, which involves different anti-inflammatory strategies for individual etiologies and stages of CHF and CKD. It may also include specific (short-term) anti-inflammatory treatments that counteract inflammation during the unsettled phases of clinical decompensation. Finally, it will require greater focus on volume overload as an increasingly significant source of systemic inflammation in the cardiorenal syndrome.

Abstract
BACKGROUND To assess the prognostic significance of four inflammatory markers (TNF-α, high sensitive C-reactive protein (hs-CRP), intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1)) in chronic heart failure (CHF) patients with respect to individual outcomes, especially disease exacerbation and mortality. METHODS Plasma adhesion molecules, ICAM-1, and VCAM-1, together with TNF-α and hs-CRP were determined in 120 CHF patients and 69 healthy controls. Endothelial function was also estimated by flow-mediated brachial artery dilatation. RESULTS Increased levels of all investigated inflammatory markers were found in CHF patients compared to controls, with the rise more pronounced in New York Heart association (NYHA) functional IV class. Significant correlations were obtained for VCAM-1 and brain natriuretic peptide (r = 0.191; P = 0.038), as well as, ICAM-1 and endothelium-dependent vasodilatation (r = -0.235; P = 0.01). Kaplan-Meier analysis showed disease exacerbation in patients with TNF-α levels >2.78 pg/ml significantly shorter compared to those with TNF-α levels <2.78 pg/ml (log-rank test = 8.270; P = 0.004), while similar association was observed for patients with hs-CRP levels >4.76 mg/l (log-rank test = 5.052; P = 0.025) and VCAM-1 levels >1200 ng/l (log-rank test = 5.45; P = 0.020) with respect to mortality. Cox regression analysis demonstrated only VCAM-1 (HR = 4.7; 95% confidence interval (CI): 1.1-18.7; P = 0.030) as independent death predictor, while TNF-α was associated with disease exacerbation (HR = 8.2; 95%CI: 1.1-23.0; P = 0.045). CONCLUSIONS VCAM-1 appears to be useful in risk stratification of CHF patients and in screening, to identify subjects at risk for heart failure related events.

Prognostic value of monocyte count in patients hospitalized for heart failure with reduced ejection fraction (from the EVEREST Trial). Am J Cardiol 2012; 110:1657-62. [PMID: 22917555 DOI: 10.1016/j.amjcard.2012.07.035] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2012] [Revised: 07/18/2012] [Accepted: 07/18/2012] [Indexed: 11/21/2022]
Abstract
Monocytes play a critical role in the pathophysiology of heart failure (HF), but few studies have evaluated the prognostic implications of an increased monocyte count in patients with HF and reduced ejection fraction (EF). The Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST) examined the effects of tolvaptan in patients with worsening HF and EF ≤40%. This post hoc analysis evaluated the primary end points of all-cause mortality and cardiovascular mortality or HF hospitalization in 3,717 patients. At baseline, 265 (7.1%) had an increased monocyte count defined by ≥800/μl. Patients with increased monocyte count tended to have an increased EF and were less likely to have a history of diabetes mellitus, hypercholesterolemia, or coronary revascularization but were more likely to have higher HF functional class and to be taking HF therapies such as diuretics, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, and digoxin (p <0.05 for all comparisons). At median follow-up of 9.9 months, increased monocyte count was predictive of all-cause mortality (hazard ratio 1.27, 95% confidence interval 1.003 to 1.60, p = 0.047) but was not associated with cardiovascular mortality or HF hospitalization (hazard ratio 1.06, 95% confidence interval 0.87 to 1.30, p = 0.55). Similar results were seen when monocyte count was analyzed as a continuous variable. However, after adjustment for baseline clinical risk factors, monocyte count was not predictive of either primary end point. In conclusion, increased monocyte count occurs in a minority of patients hospitalized with HF and is associated with poor postdischarge prognosis. However, it does not contribute prognostic value above other more traditional risk factors.

Abstract
Background Effects of fish oil on systematic inflammation in chronic heart failure remain unclear. In this meta-analysis, we aimed to evaluate the influence of fish oil supplementation on circulating levels of inflammatory markers in patients with chronic heart failure. Methods Human randomized controlled trials, which compared the effects of fish oil supplementation with placebo in patients with chronic heart failure, were identified by systematic search of Medline, Embase, Cochrane’s library and references cited in related reviews and studies up to November 2011. Outcome measures comprised the changes of circulating inflammatory markers. Meta-analysis was performed with the fixed-effect model or random-effect model according to the heterogeneity. Results A total of seven trials with eight study arms were included. The pooled results indicated circulating levels of tumor necrosis factor α (SMD = -0.62, 95% CI -1.08 to -0.16, p = 0.009), interleukin 1 (SMD = -1.24, 95% CI -1.56 to -0.91, p < 0.001) and interleukin 6 (SMD = -0.81, 95% CI -1.48 to -0.14, p = 0.02) were significantly decreased after fish oil supplementation; however, high sensitivity C reactive protein, soluble intracellular adhesion molecular 1 and vascular cell adhesion molecular 1 were not significantly affected. Meta-regression and subgroup analysis results suggested the difference in dose of fish oil and follow-up duration might influence the effects of fish oil on tumor necrosis factor α and interleukin 6. Greater reduction of these two markers might be achieved in patients taking fish oil of a higher dose (over 1000 mg/day) or for a longer duration (over 4 months). Conclusions Limited evidence suggests anti-inflammation may be a potential mechanism underlying the beneficial effects of fish oil for chronic heart failure. Further large-scale and adequately powered clinical trials are needed to confirm these effects.

Abstract
The pathophysiological basis of heart failure is cardiac remodeling, a process that comprises structural and functional changes including cardiomyocyte proliferation, hypertrophy, necrosis, apoptosis, autophagy, interstitial fibrosis, contractile dysfunction and ventricular dilatation. Accumulating evidence demonstrate that tumor necrosis factor-like weak inducer of apoptosis (TWEAK) is involved in the process by binding its receptor fibroblast growth factor-inducible molecule 14 (Fn14). In this review, we will discuss the potential role of the TWEAK/Fn14 axis in cardiac remodeling, elucidate its possible mechanisms and explore new therapeutic targets for heart failure.

Abstract
There is growing evidence to support an important role of inflammation in the underlying pathophysiology of heart failure (HF). Indeed, inflammatory cytokine levels are well recognized to be increased in patients with left ventricular dysfunction and appear to have prognostic implications. Monocytes play a pivotal role in the inflammatory cascade and are a major source of both pro- and anti-inflammatory cytokines. They are intimately involved in tissue damage and repair and an imbalance of these processes may have detrimental consequences for the failing myocardium. Importantly, monocytes comprise of distinct subsets with different cell surface markers and functional characteristics and this heterogeneity may be important in understanding their specific role in HF. In HF, monocyte activation involves interplay between pattern recognition molecules, endotoxins, cytokines, and acute phase proteins. Activated monocytes migrate to the myocardium in response to powerful chemokines, where they must then attach to the endothelial wall before infiltrating into the myocardium itself. This review article aims to discuss the role of monocytes and inflammation in HF, focusing on monocyte activation, mobilisation, recruitment and endothelial adherence, as well as the effects they may have on myocardial performance. The therapeutic modulation of inflammation and monocyte activation in HF treatment will also be reviewed.

Abstract
AIM The aim of this study was to assess levels of high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and vascular cell adhesion molecule-1 (VCAM-1) in South Indian subjects with and without MS and among MS subjects with and without insulin resistance (IR). METHODOLOGY From the population-based Chennai Urban Rural Epidemiology Study, 334 subjects with MS and 342 subjects without MS were selected. Metabolic syndrome was diagnosed based on modified National Cholesterol Education Program criteria. High-sensitivity C-reactive protein, TNF-α, IL-6, and VCAM-1 were measured by enzyme-linked immunosorbent assay. Insulin resistance was calculated using the homeostasis model assessment (HOMA-IR) using the following formula: fasting insulin (µIU/ml) × fasting glucose (mmol/liter)/22.5. RESULTS Subjects with MS had significantly higher levels of all four inflammatory markers compared to those without MS: hs-CRP (2.57 vs 2.19 mg/liter) (p < .05), TNF-α (4.47 vs 3.89 pg/ml) (p < .05), IL-6 (16.22 vs 10.96 pg/ml) (p < .05), and VCAM-1 (13.8 vs 7.94 pg/ml) (p < .05). In the total study subjects, hs-CRP (r = 0.089, p = .047), TNF-α (r = 0.113, p = .040), IL-6 (r = 0.176, p = .042), and VCAM-1 (r = 0.230, p = .06) were significantly correlated with MS. With increasing quartiles of IR, mean levels of hs-CRP (p for trend <.001) and TNF-α (p for trend <.05) increased linearly. MS subjects with IR had higher levels of hs-CRP (p < .001) and TNF-α (p < .05) compared to MS subjects without IR. CONCLUSION In Asian Indians, inflammatory cytokines hs-CRP, TNF-α, IL-6, and VCAM-1 are elevated in subjects with MS while hs-CRP and TNF-α are further elevated in those with MS and IR.

Abstract
OBJECTIVES To examine the prognostic value of soluble cellular adhesion molecules (CAMs) and highly sensitive C reactive protein (hsCRP) on long-term outcome for patients with stable angina pectoris (SAP). DESIGN In a prospective study, 291 patients referred for coronary angiography due to clinically suspected SAP had serum level of soluble intercellular adhesion molecule-1 (sICAM-1), vascular adhesion molecule-1 (sVCAM-1), sP-selectin and hsCRP determined at baseline. The primary outcome was predefined as death from any cause, myocardial infarction or stroke during a mean follow-up of 7.1 years. RESULTS Thirty four patients experienced the primary outcome. Hazard ratios and 95% confidence intervals for the primary outcome were: sVCAM-1: 2.4 [1.1-4.9], sICAM-1: 3.3 [1.5-7.2], sP-selectin: 1.2 [0.6-2.6] and hs-CRP: 3.1 [1.5-6.3], when comparing patients in the 4th quartile with those in lower quartiles in a multivariable model. Higher risk of adverse outcome was observed in patients having levels of both hsCRP and sICAM-1 (HR 4.7 [1.7-9.9]) or hsCRP and sVCAM-1 (HR 4.2 [1.7-9.9]) in the 4th quartile. CONCLUSIONS sVCAM-1, sICAM-1 and hsCRP were significantly associated with long term outcomes of patients with SAP beyond the risk associated with traditional risk factors. Risk predictions were improved when combining information about sCAMs and hsCRP.

Abstract
SUMMARY BACKGROUND Thromboembolism is a relatively common complication of chronic heart failure (HF) and the place of antiplatelet therapy is uncertain. OBJECTIVES We characterized the rate of thromboxane and prostacyclin biosynthesis in chronic HF of ischemic origin, with the aim of separating the influence of HF on platelet activation from that of the underlying ischemic heart disease (IHD). PATIENTS AND METHODS We compared urinary 11-dehydro-thromboxane (TX)B(2), 2,3 dinor 6-keto-PGF(1alpha,) 8-iso-prostaglandin (PG)F(2alpha), and plasma N-terminal pro-brain natriuretic peptide (NT-pro-BNP), asymmetric dimethylarginine (ADMA), and soluble CD40 ligand (sCD40L), in 84 patients with HF secondary to IHD, 61 patients with IHD without HF and 42 healthy subjects. RESULTS HF patients not on aspirin had significantly higher urinary 11-dehydro-TXB(2) as compared with healthy subjects (P < 0.0001) and IHD patients not on aspirin (P = 0.028). They also showed significantly higher 8-iso-PGF(2alpha) (P = 0.018), NT-pro-BNP (P = 0.021) and ADMA (P < 0.0001) than IHD patients not on aspirin. HF patients on low-dose aspirin had significantly lower 11-dehydro-TXB(2) (P < 0.0001), sCD40L (P = 0.007) and 2,3-dinor-6-keto-PGF(1alpha) (P = 0.005) than HF patients not treated with aspirin. HF patients in NYHA classes III and IV had significantly higher urinary 11-dehydro-TXB(2) than patients in classes I and II, independently of aspirin treatment (P < 0.05). On multiple linear regression analysis, higher NT-pro-BNP levels, lack of aspirin therapy and sCD40L, predicted 11-dehydro-TXB(2) excretion rate in HF patients (R(2) = 0.771). CONCLUSIONS Persistent platelet activation characterizes HF patients. This phenomenon is related to disease severity and is largely suppressable by low-dose aspirin. The homeostatic increase in prostacyclin biosynthesis is impaired, possibly contributing to enhanced thrombotic risk in this setting.

Abstract
BACKGROUND Inflammation is implicated in chronic heart failure (CHF). In this study, the potential inhibitory effect of peroxisome proliferator-activated receptor-alpha (PPARalpha) activator fenofibrate on monocyte adhesion in CHF patients was investigated in vitro. MATERIALS AND METHODS Isolated peripheral blood mononuclear cells (PBMCs) were collected from 36 patients (aged 65 +/- 8 years) with symptomatic CHF and from 12 healthy control subjects. The cultured human aortic endothelial cells (HAECs) were stimulated with or without 2 ng mL(-1) tumour necrosis factor-alpha (TNF-alpha) and the inhibitory effects of fenofibrate at 25, 50, 100 and 200 microM on endothelial mononuclear cell adhesion were tested. Furthermore, the HAECs were stimulated with 70% sera obtained from CHF patients and control individuals, respectively, with or without pretreatments with fenofibrate. The endothelial expression of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) was then confirmed by mRNA expression and Western blot. RESULTS We found that the increased adhesion of PBMCs to TNF-alpha-stimulated HAECs in CHF patients was reduced when the HAECs were pretreated with fenofibrate (31% inhibition, P = 0.0121). However, pretreatment of the isolated PBMCs collected from CHF patients with fenofibrate failed to suppress their adherence to TNF-alpha-stimulated HAECs. Furthermore, stimulation of cultured HAECs with CHF patient sera significantly increased VCAM-1 and ICAM-1 expression, which could also be inhibited by fenofibrate. CONCLUSIONS The fenofibrate directly inhibits monocyte binding by TNF-alpha-activated HAECs, probably through preventing up-regulation of cell adhesion molecules by endothelial cells in response to inflammatory stimuli. This PPARalpha activator may have the potential to ameliorate vascular inflammation in patients with CHF.

Abstract
BACKGROUND To determine the effects of depressive symptom severity on the circulating soluble adhesion molecule response to an acute exercise challenge in patients with heart failure (HF) compared with control subjects. METHODS Thirty-eight male HF patients and 19 male control subjects (mean age +/- SEM: 55.5 +/- 1.9) completed the Beck Depression Inventory (BDI) before undergoing a moderate 20-minute bicycle exercise at approximately 65% to 70% VO(2peak). Plasma levels of the soluble adhesion molecules P-selectin (sP-selectin) (sCD62P) and soluble intercellular adhesion molecule-1 (sICAM-1) were determined immediately before and after and 10 minutes after exercise. RESULTS Higher BDI scores moderated greater increases in sP-selectin levels in response to exercise over time in HF patients as compared with control subjects [F(1.8/84.5) = 3.25, p = .05]. Post hoc testing revealed that in HF patients, but not in control subjects, higher BDI scores were significantly associated with greater increases in sP-selectin levels over time in response to exercise [BDI by exercise interaction: F(1.6/49.6) = 5.67, p = .010]. Also, in HF patients, but not in control subjects, higher BDI scores were associated with higher sP-selectin levels at pre-exercise and postexercise time points [main effect BDI: F(1/31) = 4.86, p = .035]. CONCLUSIONS Our findings suggest that in male HF patients with increasing depressive symptom severity, levels of the adhesion molecule sP-selectin are higher before and after exercise and have greater increases in response to exercise. This could have implications for acute coronary syndromes associated with exercise and thereby may impact mortality.

Abstract
BACKGROUND Endothelial activation and vascular inflammation are thought to be the mechanisms of pulmonary hypertension. Increased expression of the intercellular adhesion molecule (ICAM-1) and raised serum level of its soluble form (sICAM-1) are found in various conditions associated with endothelial activation. METHODS Serum samples from 31 children (14 boys and 17 girls; age, 4.9 +/- 4.6 years) with congenital heart disease (CHD) collected at the time of cardiac catheterization were analyzed for sICAM-1 level. Uni- and multivariable stepwise linear regression analyses were performed for the following variables against the sICAM-1 level: age, hemoglobin, serum creatinine, systemic arterial pressure (SAP), pulmonary arterial pressure (PAP), pulmonary blood flow (Qp) and resistance (Rp), systemic blood flow (Qs) and resistance (Rs), Qp/Qs, Rp/Rs, and pulmonary and systemic oxygen saturation. RESULTS The sICAM-1 levels in children who had CHD with and without pulmonary hypertension were 411 +/- 110 and 344 +/- 81 ng/ml, respectively (p = 0.11). In the univariable models, age, serum creatinine, systolic PAP, mean PAP, diastolic PAP, Rp, and Rp/Rs were significantly correlated with sICAM-1 level. In the multiple stepwise regression model, only mean PAP remained as an independent predictor of sICAM-1 level (r = 0.55; p = 0.002). CONCLUSION Children with CHD and pulmonary hypertension had a trend toward elevated sICAM-1 compared with CHD children who had no pulmonary hypertension. A linear correlation was found between mean pulmonary arterial pressure and sICAM-1 level.

Abstract
This study determined the levels of serum soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecular-1 (sVCAM-1) in patients with different types of Keshan disease (KD), examined the relationship between Coxsackie B virus-specific IgM antibody (CBV-IgM) and sICAM-1 or sVCAM-1 in KD patients, and investigated the role of these adhesion molecules in the pathogenesis of KD and their clinical implications. The levels of serum sICAM-1, sVCAM-1 and CBV-IgM were measured by using enzyme-linked immunosorbent assay in 22 patients with chronic Keshan disease (CKD), 27 with latent Keshan disease (LKD) and 28 healthy controls. The subjects in different groups were adjusted for sex and age. Echocardiography was adopted to determine left ventricular ejection fraction (LVEF) in 22 patients with CKD. The results showed that CKD patients had significantly higher levels of sICAM-1 and sVCAM-1 than LKD patients and healthy controls (P<0.01 for all). And there was significant difference in the levels of the 2 adhesion molecules between LKD patients and healthy controls (P<0.05). A negative correlation was found between LVEF and sICAM-1 or sVCAM-1 in CKD patients. The percentage of CBV-specific IgM positive individuals in KD patients was significantly higher than that of healthy controls. In CVB-specific IgM positive patients, the levels of serum sICAM-1 and sVCAM-1 were significantly greater than those in CBV-specific IgM negative counterpart. It was concluded that the increase in the levels of sICAM-1 and sVCAM-1 suggests the progression of inflammation in KD. sICAM-1 and sVCAM-1 can promote the development of myocardial pathology and lead to poor myocardial function. The increased serum sICAM-1 and sVCAM-1 in KD patients may be related to CBV infection.

Abstract
BACKGROUND Many complications associated with congestive heart failure (CHF) have a thrombosis-related aetiology. Platelets play an important role in thrombogenesis, but it is not clear whether circulating platelets actively participate in thrombosis-related complications associated with CHF. OBJECTIVE To determine whether soluble P-selectin, platelet surface P-selectin, and total platelet P-selectin as indices of platelet activation in CHF patients-compared to 'disease controls' and 'healthy controls'-and to assess their prognostic value in CHF. METHODS We measured soluble P-selectin (sP-sel, by enzyme-linked immunosorbent assay, ELISA), total platelet P-selectin (pP-sel, by a novel 'platelet lysate' assay), platelet surface P-selectin (CD62P%G) and platelet surface CD63 (CD63%G) expression by flow cytometry-in 108 patients with stable congestive heart failure (all with left ventricular ejection fraction (LVEF) <50%). Levels were compared with 50 healthy controls and 70 'disease controls' (patients with coronary artery disease with normal left ventricular systolic function). RESULTS CHF patients and disease controls had higher sP-sel, CD62P%G and CD63%G than healthy controls. There were no significant correlations between sP-sel, pP-sel, CD62P%G and CD63%G with ejection fraction (all P>0.05). There were no differences in these markers when ischaemic and non-ischaemic aetiologies of CHF were compared. After a median follow-up of 490 days (range 340-535), there were 7 deaths, 15 hospitalizations for worsening heart failure, 1 for cardiac resynchronization therapy, 4 for revascularizations, 4 for myocardial infarctions, and 1 stroke. None of the platelet markers were predictive of the composite end-point at follow-up. CONCLUSIONS Patients with stable CHF exhibit evidence of abnormal platelet activation, despite usage of antiplatelet agents. These abnormalities did not determine prognosis and were broadly similar to those seen in 'disease controls' indicating that platelet abnormalities in CHF may simply be related to associated comorbidities.

Abstract
BACKGROUND Vascular inflammation and endothelial dysfunction are evident in patients with chronic heart failure (CHF). We hypothesized that circulating peripheral blood mononuclear cells (PBMCs) may be activated and the resultant increased endothelial monocyte adhesion may be functionally and pathophysiologically relevant in CHF. In the present study, we investigated the clinical significance of the activity of PBMCs in patients with CHF. METHODS PBMCs were isolated from 34 CHF patients, from 10 healthy volunteers (normal control group) and from 17 patients admitted for investigation of suspected coronary artery disease (disease control group). In each patient, the adhesiveness of PBMCs to cultured human aortic endothelial cells (HAECs) with or without tumor necrosis factor-alpha (TNF-alpha) stimulation was determined. Major adverse cardiac events (death, heart transplantation or hospitalization with worsening heart failure) were determined in the 34 CHF patients during a median follow-up period of 182 days. RESULTS Compared with those from both control groups and from mild CHF patients, PBMCs isolated from severe CHF patients adhered more to the HAECs. The endothelial adhesiveness of PBMCs correlated positively with the circulating levels of CAMs and can supply prognostic information in CHF patients. The difference between event-free curves based on the median levels of endothelial-PBMC adhesion was significant (log rank test, p=0.0139). CONCLUSIONS Endothelial adhesiveness of PBMCs is increased and correlated to clinical outcomes, and may be pathophysiologically relevant to the progression of CHF.

Abstract
BACKGROUND Statins may provide additional benefits in patients with cardiac failure due to their pleiotropic effects besides their cholesterol-lowering actions. In this study, we aimed to evaluate the impact of 12-week fluvastatin therapy on the inflammatory cytokines and the ventricular performance markers in patients with heart failure. METHODS AND RESULTS Fourty chronic heart failure patients, twenty with idiopathic dilated cardiomyopathy (DCM group) and 20 with ischemic cardiomyopathy (ICM group), for whom statin treatment was indicated according to Adult Treatment Panel III were included to this open label and prospective study. After a 12-week treatment with fluvastatin 80 mg/day; clinical functional capacity, echocardiographic indices of cardiac performance and inflammatory markers were evaluated. After the treatment, functional capacity (in DCM group: 2.05+/-0.4 versus 1.65+/-0.6, p=0.005; in ICM group: 2.25+/-0.5 versus 1.8+/-0.6, p=0.003), left ventricular ejection fraction, LVEF (from 30+/-5% to 33+/-5%, p=0.001 in DCM and 29+/-4% to 31+/-5%, p=0.001 in ICM group) and tissue Doppler mitral annular systolic velocity, Sm (5.8+/-1 cm/s to 7+/-1 cm/s, p=0.001 in DCM and 5.4+/-0.8 cm/s to 7+/-1 cm/s, p=0.001 in ICM group) improved. Tumor necrosis factor-alpha and interleukin-6 levels decreased, but no significant changes in high sensitive C-reactive protein and brain natriuretic peptide levels were detected with the fluvastatin treatment in both groups. CONCLUSION Fluvastatin improved cardiac functions and the clinical symptoms in HF patients with either idiopathic dilated or ischemic etiology. This positive effect of fluvastatin which might be secondary to inflammatory modulation was more marked in patients with ischemic etiology. Statins in HF deserves special attention by means of further large-scale trials.

Abstract
Over the last two decades, the pathophysiology and biomolecular basis of heart failure syndrome has reached sound and more comprehensive understanding. This knowledge has allowed expert researchers and clinicians to explore an entirely new spectrum of potential biochemical markers derived from different cellular and signaling pathways that lead to myocardial hypertrophy, chronic damage of the myocyte, apoptosis, and, ultimately, myocardial remodeling. Indeed, the link between myocardial remodeling and adverse outcomes, as well as the recognition of the myocardial interstitium as a multifunctional dynamic entity strongly influenced by systemic neurohormonal and inflammatory activation, has provided a solid ground for research of biomarkers that might correlate with severity and prognostication in chronic heart failure. This paper reviews and summarize recent literature on some of the most interesting circulating biomarkers with potential use for the stratification of patients with chronic heart failure.

Abstract
OBJECTIVES Peroxisome proliferator-activated receptor gamma is the master regulator of adipocyte differentiation and controls many adipocyte genes in response to anti-diabetic thiazolidinediones (TZDs) and lipid-lowering fibrates. We hypothesized that the combination of TZD+fibrate may be better than the sulfonylurea + statin approach regarding modifying the adipokine profile in diabetic patients with dyslipidemia. METHODS We measured the lipid profiles and circulating levels of adiponectin, resistin, and inflammatory markers before and after treatment in 24 type 2 diabetic patients with dyslipidemia (aged 64+/-9 years; M/F=5/19). The study patients were randomly assigned to receive an 8-week treatment of either rosiglitazone 4 mg daily and fenofibrate 160 mg daily (PPAR group) or glibenclamide 5 mg daily and atorvastatin 10 mg daily (non-PPAR group). RESULTS Even though the administration of sulfonylurea+statin can achieve a greater reduction of total cholesterol and LDL-cholesterol levels and a comparable glucose control compared to PPAR treatment, their administration did not change the plasma adipokine levels significantly. In contrast, a significant greater increase of the plasma concentrations of adiponectin (P<0.0001), a trend to a greater decrease of the plasma resistin levels (P=0.061), a significantly greater increase of HDL-cholesterol (P=0.002), and a significantly greater reduction of triglyceride levels (P=0.018) were seen in the PPAR group. CONCLUSIONS Considering the clinical significance of the adipokine-endothelial interaction in the progression and long-term prognosis of atherosclerosis, the differential effects of PPAR ligands and sulfonylurea+statin on plasma adipokine concentrations demonstrated in this study are interesting foci of investigation in the future.

Abstract
OBJECTIVES The objectives of this study were to examine the time course of the inflammatory response in acute coronary syndromes (ACS) and to assess the markers of inflammation and their relation to disease severity. METHODS We prospectively studied 134 patients with ACS who survived for at least 30 months. The patients were divided into four groups: acute myocardial infarction (MI) with (n=54) or without (n=46) ST-segment elevation and unstable angina with (n=14) or without (n=20) increased risk. Plasma levels of C-reactive protein (CRP), interleukin-6 (IL-6), secretory phospholipase A2 group IIA (sPLA2-IIA), and intercellular adhesion molecule-1 (ICAM-1) were measured on days 1 and 4 and after 3 and 30 months. RESULTS The highest levels of CRP and sPLA2-IIA were seen on day 4 but for IL-6 on day 1. These three markers, but not ICAM-1, were significantly related to disease severity, CKMB, and ejection fraction. Patients in Killip class II-IV had higher levels than those in Killip class I. The individual acute-phase responses correlated with marker levels at 3 and 30 months. ICAM-1 correlated with the development of congestive heart failure. CONCLUSIONS In ACS there seems to be an individual predisposition to inflammatory response. Plasma IL-6 is the first marker to rise, while sPLA2-IIA and CRP peak later. All three markers, especially CRP, may discriminate between MI and non-MI. ICAM-1 seems to reflect other aspects of the inflammatory processes than the other markers. The results emphasize the complexity of the inflammatory response in ACS and stress the need for further studies involving multiple markers.

Abstract
AIMS To study the effect of cardiac resynchronization therapy (CRT) on coronary and peripheral arterial circulation and to assess whether their changes are related to the improvement in patients' functional capacity and prognostically important biochemical markers. METHODS AND RESULTS Twenty-five patients were studied (New York Heart Association classes III and IV, left ventricular ejection fraction <35%, QRS>120 ms, mean age 66 +/- 2.1 years). Coronary blood flow (CBF), forearm blood flow (FBF), and their reserve were measured by transoesophageal echocardiography (in cm/s) and venous occlusion plethysmography (in mL/100 mL/min) at baseline and following 3 months of CRT. N-terminal-pro-brain natriuretic peptide (Nt-pro-BNP) and serum adhesion molecules, sICAM-1 and sVCAM-1 levels were also assessed. CRT induced a non-significant increase in resting CBF (baseline vs. CRT: 52.1 +/- 5.5 vs. 58.2 +/- 3.6, P: NS), whereas hyperaemic CBF was increased by CRT (baseline vs. CRT: 67.8 +/- 6.8 vs. 79.8 +/- 6.2, P < 0.05). Significant increases were observed in resting FBF (baseline vs. CRT: 1.6 +/- 0.2 vs. 2.6 +/- 0.2, P < 0.05) and hyperaemic FBF (baseline vs. CRT: 2.1 +/- 0.2 vs. 3.2 +/- 0.3, P < 0.05). The per cent difference in hyperaemic FBF was related to the per cent change in Nt-pro-BNP (r = -0.71, P < 0.05) and the per cent improvement in exercise duration (r = 0.80, P < 0.05). CONCLUSION CRT induces favourable changes in coronary and peripheral arterial function. Changes in peripheral blood flow are related to patients' improvement and may be prognostically significant.
