Systemic Immune-Inflammation Index and C-Reactive Protein/Albumin Ratio Could Predict Acute Stent Thrombosis and High SYNTAX Score in Acute Coronary Syndrome.

Acute stent thrombosis (AST) is associated with increased morbidity and mortality. The main aim of this study was to evaluate the prognostic value of the systemic immune-inflammation index (SII) and C-reactive protein (CRP) to albumin ratio (CAR) in predicting AST and high SYNTAX score in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). The criteria of the Academic Research Consortium were used to determine definite stent thrombosis.

Prognostic value of CHA2DS2-VASc score in predicting high SYNTAX score and in-hospital mortality for non-ST elevation myocardial infarction in patients without atrial fibrillation.

Objective: To evaluate the prognostic value of preprocedural CHA2DS2-VASc [congestive heart failure, hypertension, age ≥75 years (doubled), diabetes mellitus, previous stroke or transient ischemic attack (TIA) (doubled), vascular disease, age 65-74 years, female gender] score in predicting high SYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) score and in-hospital mortality for non-atrial fibrillation (AF) patients presenting with non-ST elevation myocardial infarction (NSTEMI). The CHA2DS2-VASc score used to determine thromboembolic risks in AF was recently reported to predict major adverse clinical outcomes in patients with the acute coronary syndrome, irrespective of AF.

Methods: A total of 906 patients with a diagnosis of NSTEMI who underwent coronary angiography were retrospectively enrolled and divided into three groups according to their SYNTAX scores (low, intermediate, and high).

Relationship of serum HLA-B alleles and TNF-α with rheumatic heart disease.

Background/aim: Acute rheumatic fever and rheumatic heart disease are major causes of morbidity and mortality in developing countries. Genetic studies have determined that the immune response in rheumatic heart disease is genetically controlled and that there is a close relationship between the gene of concern and the class II human leukocyte antigen (HLA) gene. The aim of this study was to evaluate the relationship of serum HLA-B alleles and tumor necrosis factor alpha (TNF-α) with rheumatic heart disease.

Analysis of MMP-7 and TIMP-2 gene polymorphisms in coronary artery disease and myocardial infarction: A Turkish case-control study.

Matrix metalloproteinase (MMP) and tissue inhibitors of metalloproteinase (TIMP) have a significant role in tissue remodeling related to cardiac function. In earlier studies, MMP-7 A-181G (rs11568818), C-153T (rs11568819), C-115T (rs17886546), and TIMP-2 G-418C (rs8179090) polymorphisms have been studied in various diseases. However, association between coronary artery disease (CAD) and these polymorphisms has been poorly studied.

Effect of serum YKL-40 on coronary collateral development and SYNTAX score in stable coronary artery disease.

Objective: Many studies have revealed a role of YKL-40 as a new inflammatory biomarker in angiogenesis, inflammation, atherosclerosis and cardiovascular events. Thus, the aim of this study was to investigate the association of serum YKL-40 level with coronary collateral development and SYNTAX score in patients with stable coronary artery disease.

Methods: A total of 165 patients who had ≥90% stenosis in at least one major coronary artery were prospectively enrolled in the study.

Increased serum YKL-40 level is associated with the presence and severity of metabolic syndrome.

Objective: Metabolic syndrome (MS) is defined by a cluster of interdependent physiological, biochemical, and clinical risk factors and linked to a state of chronic inflammation. YKL-40 is known as an inflammatory glycoprotein, which is secreted by various cell lines during inflammation. Thus, we aimed to assess the association of serum YKL-40 levels with the presence and severity of MS.

The effect of statin treatment on P-wave characteristics and atrial conduction time.

Background And Aim: The aim of this study was to evaluate the effect of statin treatment on P-wave morphology, dispersion, and tissue Doppler imaging-derived atrial conduction time (PA-TDI), which are known to be predictors of atrial fibrillation (AF).

Methods: A total of 132 patients with guideline-directed statin indications but no clinical atrial tachyarrhythmias were studied. P-wave duration, P-wave dispersion, and P-wave amplitude on surface 12-lead electrocardiogram and PA-TDI were evaluated before and after three months of statin (either atrovastatin 10-40 mg/d or rosuvastatin 10-20 mg/d) treatment.

Relationship between plasma apelin level and coronary collateral circulation.

Objective: Coronary collaterals play a crucial role during an acute ischemic attack. Angiogenesis has an important role in the formation of coronary collateral vessels. Previously, it was shown that apelin is a potential angiogenetic factor.

A shift in the balance of regulatory T and T helper 17 cells in rheumatic heart disease.

Background: Autoimmunity plays an essential role in the pathogenesis of rheumatic heart disease (RHD); however, cellular mechanisms of autoimmune response are unclear. Whereas T helper 17 (TH17) and regulatory T cells (Treg) cells share a common differentiation pathway, they play opposite roles in the immune tolerance and autoimmune diseases. Although high TH17/Treg ratio has been shown in several autoimmune diseases, no data are available in RHD.

[Oral antiplatelet therapy in the treatment of acute coronary syndrome].

In recent years, there have been rapid developments in cardiology, particularly regarding the diagnosis and treatment of acute coronary syndromes (ACS). In this article, we reviewed the position of oral antiplatelet therapy in current guidelines. Since plaque rupture in ACS leads to a contact between atheroma content and platelets, resulting in rapid platelet aggregation and formation of thrombus plug, the ACS treatment must provide an effective inhibition of platelet aggregation.

The Relationship of Serum Soluble Fas Ligand (sFasL) Level with the Extent of Coronary Artery Disease.

Fas/Fas ligand system contributes to the programmed cell death induced by myocardial ischemia. We investigated whether serum soluble Fas ligand (sFasL) level is independently related with the severity and extent of angiographically assessed coronary artery disease (CAD). We included 169 patients in this study.

Potential role of plasma myeloperoxidase level in predicting long-term outcome of acute myocardial infarction.

We investigated the prognostic importance of plasma myeloperoxidase levels in patients with ST-elevation myocardial infarction (STEMI) at long-term follow-up, and we analyzed the correlations between plasma myeloperoxidase levels and other biochemical values. We evaluated 73 consecutive patients (56 men; mean age, 56 ± 11 yr) diagnosed with acute STEMI and 46 age- and sex-matched healthy control participants. Patients were divided into 2 groups according to the median myeloperoxidase level (Group 1: plasma myeloperoxidase ≤ 68 ng/mL; and Group 2: plasma myeloperoxidase > 68 ng/mL).

The impact of dialysis type on biomarkers for cardiovascular diseases.

Objectives: The impact of dialysis type on the biomarkers that reflect the severity of cardiovascular diseases is not clearly known. We aimed to investigate the effect of dialysis type on biomarkers of cardiovascular diseases in patients with end-stage renal disease (ESRD).

Study Design: The study included 108 patients who had been on dialysis treatment (57 patients receiving hemodialysis, 51 patients receiving peritoneal dialysis) for ESRD for at least three months.

Assessment of right ventricular functions during cancer chemotherapy.

Aims: Although systolic and diastolic left ventricular functions after cancer chemotherapy are well studied, there are a few investigations about the right ventricular functions. We aimed to investigate the early effects of chemotherapy on right heart, if any, in addition to the association between N-terminal pro-brain natriuretic peptide (NT-proBNP) and right heart echocardiographic indices.

Methods And Results: Thirty-seven consecutive patients with newly diagnosed breast cancer who were planned to receive either AC protocol [cyclophosphamide (600 mg/m(2)) + adriamycin (60 mg/m(2))] or CAF protocol [cyclophosphamide (600 mg/m(2)) + adriamycin (60 mg/m(2)) + 5-fluorouracil (600 mg/m(2))] for six cures were enrolled between February 2009 and June 2010.

The relationship of serum erythropoietin level with coronary collateral grade.

Background: Erythropoietin has been shown to induce neovascularization and protect against ischemic vascular injury. We investigated whether a higher serum erythropoietin (EPO) level is related to better coronary collateral vessel grade.

Methods: Ninety-nine patients with stable angina pectoris who have at least 1 coronary stenosis of equal to or greater than 70% at coronary angiography were prospectively enrolled.

Plasma osteopontin levels in prediction of prognosis in acute myocardial infarction.

Objective: We sought to explain the clinical importance of the osteopontin (OPN) in the setting of acute ST-elevation myocardial infarction (STEMI).

Methods: Eighty consecutive patients (55 = 11 years, 12 women and 68 men) and sixty healthy control subjects were included in the study. In all patients, plasma OPN levels were assessed on admission and on the third day (peak value).

The role of matrix metalloproteinase-2 promoter polymorphisms in coronary artery disease and myocardial infarction.

The matrix metalloproteinase (MMP) family are key enzymes involved in the breakdown of the extracellular matrix in normal physiological processes, including tissue remodeling, and disease processes, such as arthritis and metastasis. The promoter polymorphism in the MMP2 gene may be responsible for multiple diseases related to extracellular matrix degradation. Therefore, we aimed to investigate the relationship between genotypes or haplotypes of -1575 G/A, -1306 C/T, -790 T/G, and -735 C/T promoter polymorphisms and coronary artery disease (CAD) with or without myocardial infarction (MI) history.

Relation between serum monocyte chemoattractant protein-1 and coronary collateral development.

Background: The degree of coronary collateral development is not same in every patient with similar degree of coronary stenosis. In animal studies monocyte chemoattractant protein-1 (MCP-1) has been found to be related to collateral vessel development. In this study we investigated whether a higher serum MCP-1 level is related to better coronary collateral vessel development in patients with stable coronary artery disease.

Congenitally severe tortuous circumflex artery fistula draining into the coronary sinus: transcatheter closure with Guglielmi detachable coils via different delivery system.

Lack of association between matrix metalloproteinase-9 and endothelial nitric oxide synthase gene polymorphisms and coronary artery disease in Turkish population.

Polymorphic variants of genes encoding proteins involved in vascular remodeling may genetically diverge among different populations and play a role in the susceptibility to the coronary artery disease (CAD). MMP-9-1562 C/T (rs3918242), eNOS T-786C (rs2070744), and Glu298Asp (rs1799983) are among the most studied of these polymorphisms. The aim of this study was to determine the relationship between CAD and these polymorphisms in the Turkish population.
