INTRODUCTION Formation of compact and poorly lysable fibrin clots have been demonstrated in patients following ischemic stroke. Recently, it has been shown that denser fibrin networks and impaired fibrinolysis occurs in subjects with permanent atrial fibrillation (AF). Fibrin clot phenotype in other types of AF remains to be established. We evaluated fibrin(More)
BACKGROUND Acute coronary syndrome (ACS) is associated with thrombin formation, triggered by ruptured or eroded coronary atheroma. We investigated whether thrombin generation based on circulating coagulation protein levels, could distinguish between acute and stable coronary artery disease (CAD). METHODS AND RESULTS Plasma coagulation factor (F)(More)
BACKGROUND Inflammatory bowel disease (IBD) is associated with an increased risk of thromboembolism. Its mechanism is still unclear. Altered fibrin clot properties have been reported in patients with thromboembolism and those with chronic inflammatory states. We investigated whether fibrin characteristics are abnormal in IBD. METHODS Ex vivo plasma fibrin(More)
AIMS Beneficial effects of statins in preventing cardiovascular events may depend, at least in part, on their anti-inflammatory action. The aim of the study was to assess the influence of simvastatin and aspirin on serum levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in hypercholesterolemic subjects.

OBJECTIVES The purpose of this study was to investigate whether omega-3 polyunsaturated fatty acids (PUFAs) are able to modify platelet responsiveness to dual antiplatelet therapy in stable coronary artery disease patients undergoing percutaneous coronary intervention (PCI). BACKGROUND Although previous studies have suggested antiplatelet properties of(More)

Accumulating evidence indicates that accelerated formation of fibrin clots composed of compact, highly-branched networks with thin fibres which are relatively resistant to plasmin-mediated lysis can be commonly observed in patients with venous or arterial thrombosis. This review discusses characteristics of fibrin clot structure and function in patients(More)
OBJECTIVES We investigated whether markers of platelet, neutrophil and endothelial activation, plasma fibrin clot properties and patient clinical profile may characterize coronary thrombus composition in ST-segment elevation myocardial infarction (STEMI) patients. METHODS A total of 40 intracoronary thrombi obtained 4.0-16.5 h since chest pain onset by(More)
A single nucleotide T to C transition of the gene encoding glycoprotein IIIa leads to a common diallelic polymorphism Leu-33-->Pro (PLA1/A2). We studied the relationship between the PlA1/A2 polymorphism and platelet function in 80 healthy men, aged 20-25 years. Before aspirin ingestion, bleeding time (BT) was shorter in carriers of the PlA2 than in carriers(More)
The 3-hydroxy-3-methylglutaryl (HMG)-coenzyme A (CoA) reductase inhibitors (statins) have been shown to exhibit several vascular protective effects, including antithrombotic properties, that are not related to changes in lipid profile. There is growing evidence that treatment with statins can lead to a significant downregulation of the blood coagulation(More)
BACKGROUND Stable angina is associated with unfavorable fibrin structure/function. It is not known how acute coronary syndromes (ACS) affect fibrin architecture. OBJECTIVE We investigated fibrin clot properties and their determinants in ACS patients. PATIENTS AND METHODS Clot permeability, turbidity and fibrinolysis were assessed in 40 patients with ACS(More)
