Platelet Aggregation Inhibitors
Tissue Plasminogen Activator
A proteolytic enzyme in the serine protease family found in many tissues which converts PLASMINOGEN to FIBRINOLYSIN. It has fibrin-binding activity and is immunologically different from UROKINASE-TYPE PLASMINOGEN ACTIVATOR. The primary sequence, composed of 527 amino acids, is identical in both the naturally occurring and synthetic proteases.
A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.
Sinus Thrombosis, Intracranial
Formation or presence of a blood clot (THROMBUS) in the CRANIAL SINUSES, large endothelium-lined venous channels situated within the SKULL. Intracranial sinuses, also called cranial venous sinuses, include the superior sagittal, cavernous, lateral, petrous sinuses, and many others. Cranial sinus thrombosis can lead to severe HEADACHE; SEIZURE; and other neurological defects.
Platelet Glycoprotein GPIIb-IIIa Complex
Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. It is an integrin complex containing INTEGRIN ALPHAIIB and INTEGRIN BETA3 which recognizes the arginine-glycine-aspartic acid (RGD) sequence present on several adhesive proteins. As such, it is a receptor for FIBRINOGEN; VON WILLEBRAND FACTOR; FIBRONECTIN; VITRONECTIN; and THROMBOSPONDINS. A deficiency of GPIIb-IIIa results in GLANZMANN THROMBASTHENIA.
Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)
Carotid Artery Thrombosis
Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.
Percutaneous Coronary Intervention
A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.
Sagittal Sinus Thrombosis
Formation or presence of a blood clot (THROMBUS) in the SUPERIOR SAGITTAL SINUS or the inferior sagittal sinus. Sagittal sinus thrombosis can result from infections, hematological disorders, CRANIOCEREBRAL TRAUMA; and NEUROSURGICAL PROCEDURES. Clinical features are primarily related to the increased intracranial pressure causing HEADACHE; NAUSEA; and VOMITING. Severe cases can evolve to SEIZURES or COMA.
Coronary Care Units
Intracranial Embolism and Thrombosis
Tomography, X-Ray Computed
A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
Upper Extremity Deep Vein Thrombosis
DEEP VEIN THROMBOSIS of an upper extremity vein (e.g., AXILLARY VEIN; SUBCLAVIAN VEIN; and JUGULAR VEINS). It is associated with mechanical factors (Upper Extremity Deep Vein Thrombosis, Primary) secondary to other anatomic factors (Upper Extremity Deep Vein Thrombosis, Secondary). Symptoms may include sudden onset of pain, warmth, redness, blueness, and swelling in the arm.
Coronary Artery Bypass, Off-Pump
Heparin fractions with a molecular weight usually between 4000 and 6000 kD. These low-molecular-weight fractions are effective antithrombotic agents. Their administration reduces the risk of hemorrhage, they have a longer half-life, and their platelet interactions are reduced in comparison to unfractionated heparin. They also provide an effective prophylaxis against postoperative major pulmonary embolism.
Blood Flow Velocity
Cavernous Sinus Thrombosis
Formation or presence of a blood clot (THROMBUS) in the CAVERNOUS SINUS of the brain. Infections of the paranasal sinuses and adjacent structures, CRANIOCEREBRAL TRAUMA, and THROMBOPHILIA are associated conditions. Clinical manifestations include dysfunction of cranial nerves III, IV, V, and VI, marked periorbital swelling, chemosis, fever, and visual loss. (From Adams et al., Principles of Neurology, 6th ed, p711)
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
Vena Cava, Inferior
The presence of antibodies directed against phospholipids (ANTIBODIES, ANTIPHOSPHOLIPID). The condition is associated with a variety of diseases, notably systemic lupus erythematosus and other connective tissue diseases, thrombopenia, and arterial or venous thromboses. In pregnancy it can cause abortion. Of the phospholipids, the cardiolipins show markedly elevated levels of anticardiolipin antibodies (ANTIBODIES, ANTICARDIOLIPIN). Present also are high levels of lupus anticoagulant (LUPUS COAGULATION INHIBITOR).
Fibrin Fibrinogen Degradation Products
Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.
Severity of Illness Index
Lateral Sinus Thrombosis
Formation or presence of a blood clot (THROMBUS) in the LATERAL SINUSES. This condition is often associated with ear infections (OTITIS MEDIA or MASTOIDITIS) without antibiotic treatment. In developed nations, lateral sinus thrombosis can result from CRANIOCEREBRAL TRAUMA; BRAIN NEOPLASMS; NEUROSURGICAL PROCEDURES; THROMBOPHILIA; and other conditions. Clinical features include HEADACHE; VERTIGO; and increased intracranial pressure.
Intravenous magnesium reduces infarct size after ischemia/reperfusion injury combined with a thrombogenic lesion in the left anterior descending artery. (1/1009)Experimental studies have demonstrated that intravenous magnesium (Mg) can protect the ischemic myocardium and has an antithrombotic effect. In patients with myocardial infarction, the reperfusion injury is complicated by the presence of a thrombogenic area in the affected coronary artery that may cause repetitive thrombus formation and embolization. We investigated the effect of Mg on infarct size in a randomized study in pigs. Myocardial infarction was induced by a 50-minute mechanical occlusion of the left anterior descending artery combined with an arterial injury, which stimulated a dynamic thrombus formation with emboli shedding on reperfusion. Magnesium sulfate (6 mmol/20 min plus 3 mmol/h) or saline was started at 30 minutes after coronary occlusion. Real-time ventricular pressure-volume loops were generated from the left ventricle by using a microtip pressure manometer and a conductance catheter. Platelet accumulation in the myocardium was evaluated by using 111In-labeled platelets. After 4 hours of reperfusion, the infarct size/area at risk ratio in the placebo group was 46+/-0.06% (n=8) compared with 22+/-0.07% (n=6) in the Mg-treated animals (P=0. 03). Ejection fraction decreased significantly in the control group but not in the Mg-treated animals (P=0.03). Platelet accumulation in the myocardium did not change significantly between the Mg- and placebo-treated animals (placebo group, 191+/-19%; Mg group, 177+/-29%; NS). The present study demonstrates that intravenous Mg infusion is able to reduce infarct size by >50% and preserve the ejection fraction in this model where ischemia/reperfusion injury was evaluated in the presence of a thrombogenic area in the nutrient artery.

A role for changes in platelet production in the cause of acute coronary syndromes. (2/1009)Platelets are heterogeneous with respect to their size, density, and reactivity. Large platelets are more active hemostatically, and platelet volume has been found to be increased both in patients with unstable angina and with myocardial infarction. Furthermore, platelet volume is a predictor of a further ischemic event and death when measured after myocardial infarction. Platelets which are anucleate cells with no DNA are derived from their precursor, the megakaryocyte. Therefore, it is suggested that changes in platelet size are determined at thrombopoiesis in the megakaryocyte and that those changes might precede acute cardiac events. Understanding of the signaling system that controls platelet production may also further elucidate the cascade of events leading to acute vascular occlusion in some patients. (+info)
Endothelial injuries of coronary arteries distal to thrombotic sites: role of adhesive interaction between endothelial P-selectin and leukocyte sialyl LewisX. (3/1009)Intracoronary thrombus formation is associated with epicardial vasoconstriction distal to the thrombotic site. To investigate the mechanisms of abnormal vasomotor function of the artery distal to the thrombotic site, we studied coronary vessels in dogs with cyclic flow variations (CFVs) of the left anterior descending coronary artery (LAD) stenosis with endothelial injury. Coronary rings isolated from the LAD (proximal, stenotic, and distal sites) and control circumflex coronary arteries were tested for responsiveness to endothelium-dependent (acetylcholine and A23187) and endothelium-independent vasodilators (NaNO2). Endothelium-independent relaxation was intact in all 4 sites. Endothelium-dependent relaxation was intact in the control and proximal sites and impaired in the stenotic sites. Relaxations not only to acetylcholine and A23187 but also to serotonin, ADP, and thrombin were impaired in the distal sites after observing CFVs for 80 minutes. Electron microscopy revealed the loss of endothelial integrity with leukocyte adherence to the endothelium in the distal sites. Immunohistochemical expression of P-selectin on the endothelial cells was more upregulated in the distal site than in the proximal site, and P-selectin mRNA expression was significantly greater in the ischemic region distal to the thrombotic site than in the proximal nonischemic region. PB1.3, a neutralizing monoclonal antibody against P-selectin, and sialyl LewisX (SLeX)-containing oligosaccharide SLeX, a carbohydrate analogue of selectin ligand, preserved endothelial function without affecting CFVs. SLeX-containing oligosaccharide preserved endothelial integrity of the distal site and inhibited P-selectin expression of the distal site. Thus, the adhesive interaction between endothelial P-selectin and leukocyte SLeX may play an important role in endothelial injuries of the coronary artery distal to the thrombotic site. (+info)
Antithrombotic efficacy of thrombin inhibitor L-374,087: intravenous activity in a primate model of venous thrombus extension and oral activity in a canine model of primary venous and coronary artery thrombosis. (4/1009)The small molecule direct thrombin inhibitor L-374,087 was characterized across species in an in vitro activated partial thromboplastin clotting time (aPTT) assay and in vivo in rhesus monkey and dog thrombosis models. In vitro in rhesus, dog, and human plasma, L-374,087 concentrations eliciting 2-fold increases in aPTT were 0.25, 1.9, and 0.28 microM, respectively. In anesthetized rhesus monkeys, 300 microgram/kg bolus plus 12 microgram/kg/min and 300 microgram/kg bolus plus 30 microgram/kg/min L-374,087 i.v. infusions significantly reduced jugular vein thrombus extension, with both regimens limiting venous thrombus extension to 2-fold that of baseline thrombus mass compared with a 5-fold extension observed in the vehicle control group. Antithrombotic efficacy in the rhesus with the lower-dose regimen was achieved with 2.3- to 2.4-fold increases in aPTT and prothrombin time. In a conscious instrumented dog model of electrolytic vessel injury, the oral administration of two 10 mg/kg L-374,087 doses 12 h apart significantly reduced jugular vein thrombus mass, reduced the incidence of and delayed time to occlusive coronary artery thrombosis, and significantly reduced coronary artery thrombus mass and ensuing posterolateral myocardial infarct size. Antithrombotic efficacy in the dog was achieved with 1.6- to 2.0-fold increases in aPTT at 1 to 6 h after oral dosing with L-374,087. These results indicate significant antithrombotic efficacy against both venous and coronary arterial thrombosis with L-374,087 with only moderate elevations in aPTT or prothrombin time. The oral efficacy of L-374,087 characterizes this compound as a prototype for the further development of orally active direct thrombin inhibitors. (+info)
Lipoprotein(a) and coronary thrombosis and restenosis after stent placement. (5/1009)OBJECTIVES: The objective of this prospective study was to evaluate the relation between high lipoprotein(a) levels and thrombotic and restenotic events after coronary stent implantation. BACKGROUND: Lipoprotein(a) may promote atherogenesis, coronary thrombosis and restenosis after balloon angioplasty, but the clinical significance remains unclear. METHODS: The study included 2,223 consecutive patients with successful coronary stent placement. According to the serum level of lipoprotein(a), patients were divided in two groups: 457 patients of the highest quintile formed the high lipoprotein(a) group, and 1,766 patients of the lower four quintiles formed the low lipoprotein(a) group. Primary end points were the incidence of angiographic restenosis at six months and the event-free survival at one year. Secondary end point was the incidence of angiographic stent occlusion. RESULTS: Early stent occlusion occurred in four of the 457 patients (0.9%) with high and 37 of the 1,766 patients (2.1%) with low lipoprotein(a) levels, odds ratio of 0.41 (95% confidence interval, 0.15 to 1.16). Angiographic restenosis occurred in 173 of the 523 lesions (33.2%) in the high lipoprotein(a) group and 636 of the 1,943 lesions (32.7%) in the low lipoprotein(a) group, odds ratio of 1.02 (0.83 to 1.25). The probability of event-free survival was 73.0% in the high lipoprotein(a) group and 74.8% in the low lipoprotein(a) group (p = 0.45). On the basis of the findings in the low lipoprotein(a) group, the power of this study to detect a 25% increase in the incidence of restenosis and adverse events in the group with elevated lipoprotein(a) was 90% and 75%, respectively. CONCLUSIONS: Elevated lipoprotein(a) levels did not influence the one-year clinical and angiographic outcome after stent placement. Thrombotic events and measures of restenosis were not adversely affected by the presence of high lipoprotein(a) levels. (+info)
Antithrombin activity during the period of percutaneous coronary revascularization: relation to heparin use, thrombotic complications and restenosis. (6/1009)OBJECTIVES: This study evaluated changes in antithrombin (AT) activity around the time of percutaneous transluminal coronary revascularization (PTCR) with unfractionated heparin anticoagulation and the effects these changes had on major thrombotic complications of PTCR. BACKGROUND: Heparin is used during PTCR to prevent thrombosis. However, heparin, a cofactor for AT, causes AT activity to fall. AT activity <70% is associated with thrombosis. There is a prothrombotic state after heparin discontinuation that has not been well explained. METHODS: Antithrombin activity was sampled at the start and end of PTCR and the next two mornings in 250 consecutive patients. We recorded occurrence of major thrombotic events, defined as 1) major thrombotic complications of PTCR; 2) major in-lab thrombus formation; or 3) subacute occlusion. Discriminant analysis was employed to evaluate the relationship of AT activity to these events. Change in AT activity and its relationship to heparin was evaluated. Evidence of restenosis at six months was obtained. RESULTS: There were 14 major thrombotic events. Antithrombin activity <70% was strongly (p = 0.006) associated with these events. The AT activity fell significantly through the morning after PTCR when 21% of patients had AT activity <70%; AT activity did not normalize until >20 h after heparin discontinuation. Pre-PTCR use of heparin led to lower AT activity in proportion to duration of heparin use. There was no relationship between AT activity and restenosis. CONCLUSIONS: Low AT activity may contribute to major thrombotic complications of PTCR. The way heparin is used before and after PTCR is important to development of low AT activity. (+info)
Pravastatin therapy in hyperlipidemia: effects on thrombus formation and the systemic hemostatic profile. (7/1009)OBJECTIVES: The study sought to determine the effects of lipid-lowering with pravastatin on the systemic fibrinolytic profile and on thrombus formation under dynamic flow conditions. BACKGROUND: Lowering cholesterol (C) decreases clinical events in coronary artery disease (CAD) patients, but an analysis of the effects of lipid-lowering on the entire hemostatic and thrombotic profile has not been conducted. METHODS: We prospectively studied 93 stable patients with untreated low-density lipoprotein cholesterol (LDL-C) >145 mg/dl. The CAD patients received pravastatin, and non-CAD patients were randomized to pravastatin versus placebo (double-blind). Thrombus formation upon an injured vascular surface was assessed in a substudy of 40 patients with a previously validated ex vivo perfusion chamber system. Systemic hemostatic markers and thrombus formation were evaluated at baseline, three and six months. RESULTS: Placebo produced no changes in either the lipid profile, any of the hemostatic markers, or the ex vivo thrombus formation. Both pravastatin groups (CAD and non-CAD) showed decreased LDL-C by 30% within 6 weeks (188 to 126 mg/dl, p < 0.001 vs. baseline), and decreased plasminogen activator inhibitor-1 at 3- and 6-month follow-up compared to baseline (15% to 18% decrease at 3 months and 21% to 23% at 6 months). For the tissue plasminogen activator antigen, CAD and non-CAD groups showed significant decreases at 6 months compared to baseline (10% and 13%, respectively). No significant changes were observed with treatment in d-dimer, fibrinopeptide A, prothrombin fragment F1.2, factor VIIa, von Willebrand factor, or C-reactive protein. Fibrinogen levels were significantly increased at 6 months compared to baseline, though still below the upper normal limit. In the perfusion chamber substudy, there was a decrease in thrombus area in non-CAD patients treated with pravastatin at both 3 and 6 months compared to baseline (by 21% and 34%, respectively). The CAD patients showed decreases in thrombus formation by 13% at 3 months, and by 16% at 6 months. The change in LDL-C- correlated modestly with the change in thrombus formation (r = 0.49; p < 0.01). CONCLUSIONS: Pravastatin therapy significantly decreased thrombus formation and improved the fibrinolytic profile in patients with and without CAD. These early effects may, in part, explain the benefit rendered in primary and secondary prevention of CAD. (+info)
Adhesive interaction between P-selectin and sialyl Lewis(x) plays an important role in recurrent coronary arterial thrombosis in dogs. (8/1009)Cell adhesion molecules may play an important role in the disease process of acute coronary syndromes. We have shown a neutralizing anti-P-selectin monoclonal antibody and a sialyl Lewis(x)-containing oligosaccharide (SLe(x)-OS), an analogue of selectin ligand on leukocytes, reduce cyclic flow variations (CFVs) in a canine model of recurrent coronary arterial thrombosis, suggesting the important interaction between P-selectin and SLex for the pathophysiology of these syndromes. However, the functional role of these adhesion molecules in the thrombotic process remains unclear. Therefore, we investigated effects of SLe(x)-OS on CFVs, platelet P-selectin expression, and morphology of the stenotic site in the same model. Anesthetized open-chest dogs (n=34) were randomly divided into 4 groups after developing CFVs. Dogs intravenously received saline or graded doses of SLe(x)-OS (5, 20, or 40 mg/kg bolus) infusion followed by a continuous infusion (5 mg. kg-1. h-1) for 60 minutes. By flow cytometric analysis, P-selectin expression on platelets after CFVs was significantly upregulated during CFVs. Immunohistochemical analysis revealed the incorporation of platelets with upregulated P-selectin within thrombi at the stenotic site. Microscopic observations revealed the presence of numerous platelets adhered to leukocytes at the stenotic site on the damaged endothelium. SLe(x)-OS significantly reduced CFVs, inhibited the P-selectin expression on platelets, and prevented the adherence of platelets and leukocytes. These findings further support the notion that the adhesive interaction between P-selectin on platelets and SLe(x) on leukocytes plays an important role in platelet-mediated thrombus formation in this model.

TY - JOUR. T1 - Molecular imaging identifies regions with microthromboemboli during primary angioplasty in acute coronary thrombosis. AU - Sakuma, Tadamichi. AU - Sklenar, Jiri. AU - Leong-Poi, Howard. AU - Goodman, Norman C.. AU - Glover, David K.. AU - Kaul, Sanjiv. PY - 2004/7/1. Y1 - 2004/7/1. N2 - Microthromboemboli (MTE) may contribute to the no-reflow phenomenon in acute myocardial infarction (AMI) either spontaneously or after primary percutaneous transluminal coronary angioplasty (PTCA). We hypothesized that myocardial MTE in acute coronary syndromes can be identified on imaging by in vivo 99mTc labeling of the coronary thrombus with a compound that binds to the glycoprotein IIb/IIIa present on activated platelets (DMP-444). Methods: Fifteen dogs underwent left anterior descending coronary artery (LAD) injury in to produce thrombus, whereas 5 control dogs had LAD ligation. Before recanalization, the risk area (RA) and myocardial blood flow (MBF) were measured, and in vivo thrombus ...
Multiple Simultaneous Plaque Erosion in 3 Coronary Arteries | JACC: Cardiovascular Imaging
Plaque erosion is suspected in the presence of an acute luminal thrombus that is in direct contact with the underlying intima comprising smooth muscle cells and proteoglycan with an absence of endothelial lining (1). The erosive plaques are rich in versican, hyaluronan, and type III collagen, unlike rupture or stable plaques, which are rich in type I collagen (2). The erosion lesions are more often eccentric and infrequently calcified; they show minimal inflammation with a few or absent macrophages and T-lymphocytes (2). The media underneath plaque erosions are similar to plaques with mild stenosis, rich in smooth muscle cell actin, which is also highly expressed in intimal smooth muscle cells in erosions. Plaque erosions often show negative remodeling. It is likely that spasm may play an important role in plaque erosion.. Plaque erosion accounts for 25% to 35% of coronary thrombi in patients dying of acute myocardial infarction and/or sudden coronary death (1). Plaque erosions occur in ...
Do We Know What Causes Very Late Drug-Eluting Stent Thrombosis? | JACC: Cardiovascular Interventions
The Academic Research Consortium (ARC) divides stent thrombosis (ST) into early (within 30 days), late (30 days to 1 year), and very late (beyond 1 year). Intravascular imaging studies, to date mostly using intravascular ultrasound (IVUS), have provided clues with regard to the causes of ST-primarily by focusing on either early or very late ST, although each study usually includes a small number of patients with events between 30 days and 1 year. In this issue of JACC: Cardiovascular Interventions, the current study is similar in that 15 of 18 patients have very late ST with only 3 patients presenting earlier than 1 year (and those 3 at least 172 days) after implantation (1).. The distinction between patients with early versus very late ST is important, especially after drug-eluting stent (DES) implantation. Studies should not combine these 2 groups of patients, because their fundamental mechanisms seem to be different.. The IVUS-identified causes or predictors of early ST are mechanical and ...
THE INITIAL VENTRICULAR COMPLEX OF THE ELECTROCARDIOGRAM IN CORONARY THROMBOSIS* | Annals of Internal Medicine | American...
The changes in the final ventricular complex, the T-wave, and in the S-T segment of the electrocardiogram in coronary thrombosis have been extensively studied, both experimentally and clinically, since the early works of Herrick,1 Smith,2 and Pardee.3 As a result, it has been generally accepted that characteristic changes do occur in the majority of the cases, following an attack of coronary thrombosis.. In contrast, the changes in the initial ventricular complex have, up to recent years, received much less attention. Smith2 and Wearn4 observed that in coronary thrombosis the initial ventricular complex may not rarely be of a very small ...
Small Peptide Radiopharmaceuticals in the Imaging of Acute Thrombus | Bentham Science
Title: Small Peptide Radiopharmaceuticals in the Imaging of Acute Thrombus. VOLUME: 8 ISSUE: 20. Author(s):Jay E. Blum and Hirsch Handmaker. Affiliation:Section of Pulmonary Diseases, CIGNA Medical Group, 755 East McDowell Road, Phoenix,Arizona 85006, USA. Keywords:radiopharmaceuticals, acute thrombus, contrast venography, clotting process, vascular magnetic resonance scanning, receptor-receptor binding. Abstract: Until recently, imaging acute thrombus, especially the very prevalent condition of acute deep vein thrombosis relied on conventional imaging techniques utilizing either ultrasonography or contrast venography. The former procedure is limited by accuracy and the latter by technical considerations. Newer modalities such as magnetic resonance and computed tomographic scanning are yet to be validated in a prospective manner. Recent advances in the understanding of the pathogenesis of acute clot at the molecular level have suggested new avenues for detection of the acute thrombotic process ...
Impact of Late Drug-Eluting Stent Malapposition on 3-Year Clinical Events | JACC: Journal of the American College of Cardiology
To the Editor:. There are questions regarding long-term safety of drug-eluting stents (DES), especially concern about an increased rate of late DES thrombosis compared with bare-metal stents. Numerous intravascular ultrasound (IVUS) studies have reported an increased frequency of late stent malapposition (LSM) in patients with DES (1-3), speculating that there may be a relationship between LSM and late stent thrombosis. The present study reports the long-term (,2 years) follow-up after the diagnosis of LSM was made using serial IVUS examination after DES implantation.. We previously reported 82 patients (85 lesions) with LSM from an overall cohort of 557 patients (705 native lesions) who underwent DES implantation (mean interval between baseline and follow-up IVUS of 6.1 ± 2.1 months). No intervention was performed in 542 patients (683 lesions) at 6-month follow-up (3). At least 2-year follow-up was available for all but 10 patients (12 lesions). Therefore, the present study reports 532 ...

Two Cases of Coronary Stent Thrombosis Very Late After Bare-Metal Stenting | JACC: Cardiovascular Interventions
Medical literature has recently focused on very late stent thrombosis (VLST) after drug-eluting stent implantation, while its mechanistic issue was not fully explored in the bare-metal stent (BMS) era. The first case is a 59-year-old man presenting with inferior non-ST-segment elevation myocardial infarction, 4 years after BMS implantation (NIR 3.5/18 mm, Boston Scientific, Galway, Ireland) for a chronic total occlusion lesion in the proximal right coronary artery. Coronary angiograms showed Thrombolysis In Myocardial Infarction (TIMI) flow grade 1 and filling defects in the BMS deployed previously, and massive red thrombi attaching to uncovered stent struts were found by angioscope (Fig. 1,Online Video 1). Thrombectomy and adjunctive balloon angioplasty were performed based on the angioscopic findings, and TIMI flow grade 3 was obtained. The second case is a 71-year-old man who was admitted for a diagnosis of inferior non-ST-segment elevation myocardial infarction 10 years after a treatment ...
Proportion of fibrin and platelets differs in thrombi on ruptured and eroded coronary atherosclerotic plaques in humans | Heart
The present study showed that the thrombi of ruptured plaques were more significantly rich in fibrin and that more tissue factor and CRP were expressed in ruptured than in eroded plaques.. Acute coronary thrombosis leading to acute myocardial infarction may arise from a difference in underlying plaque morphology, namely rupture and superficial erosion.2-6 In acute coronary death with coronary thrombosis, two necropsy studies have found plaque rupture in 75% of cases and that erosion accounted for the remainder.2,6 Kojima and colleagues5 found plaque rupture in 81% and erosion in 19% of Japanese patients who died of acute myocardial infarction.5 The findings of the present study agree with these previous results. In contrast, Farb and colleagues3 and Burke and associates4 have reported that 56% of such deaths are associated with plaque rupture and 44% with erosion. In addition, they found plaque erosion in 69% of women who died of sudden ischaemic heart disease.3,4 These reports emphasised a high ...
Frequency and correlates of coronary stent thrombosis in the modern era | JACC: Journal of the American College of Cardiology
A number of risk factors for stent thrombosis have been identified by previous investigators. Persistent dissection, longer stent length, and final lumen diameter within the stent were identified as independent multivariable predictors of stent thrombosis in a meta-analysis of 6,186 patients enrolled in six major clinical trials of coronary stenting (17). Other studies have identified balloon size ≤2.5 mm, bail-out situations, unstable angina or acute MI (15), ejection fraction, use of a combination of different stents, postprocedural dissections, and slow flow (16)as predictive of stent thrombosis.. Multivariate analysis of correlates of stent thrombosis is difficult to perform in even a study as large as this because of the low incidence of the primary end point. A common method of avoiding over-fitting is bootstrap model selection. It involves creating random data sets from the patient population, selecting correlates with stepwise model selection for each bootstrap sample, and counting the ...
the 1950s and 1960s debate raged as to whether coronary thrombosis - Outlook on PI3K/AKT/mTOR inhibition
the 1950s and 1960s debate raged as to whether coronary thrombosis was the cause or the consequence of ST-segment elevation myocardial infarction (STEMI). of lidocaine was common in the United States and in some European countries but was used sparingly in the United Kingdom and elsewhere. Exercise stress testing was rarely done soon after STEMI because of Ondansetron HCl safety concerns. Early coronary arteriography (in the first few days after STEMI) was rare even in the late 1980s. Since then we have seen marked changes in the management of patients with STEMI.1 2 3 4 In 1980 DeWood and colleagues5 reported that about 80% of patients with acute MI had coronary occlusion measured using coronary arteriography and that the occlusion was due to an intraluminal thrombus. Later studies showed that the coronary thrombus could be dissolved with intracoronary (and later intravenous) administration of streptokinase and a meta-analysis demonstrated a reduction in mortality. Experts remained skeptical ...
Abstract 19704: Significant Correlation between Primitive Cells in Intracoronary Thrombi in Patients with Myocardial Infarction...
Background Clinical evidence suggests that intracoronary thrombus formation is associated with a high incidence of late restenosis after successful coronary intervention in patients with myocardial infarction. However, little is known about the mechanism by which intracoronary thrombi play pathological roles.. Methods and Results We analyzed the cellular constituents of 108 thrombi aspirated from coronary lesions with a thrombectomy device in 62 patients who underwent emergent coronary intervention for the treatment of acute (,24 hours) or recent (24∼72 hours) ST-segment-elevation myocardial infarction (44 male, 18 female, age 68.0±19.3 years). Immunohistological analysis of aspirated thrombotic materials revealed that the content of platelets, as determined by immunostaining for CD42a, had a negative correlation with the time after the onset of chest pain (correlation coefficient: −0.683, p,0.01). Immunofluorescent staining for CD34 and breast cancer resistant protein-1 (bcrp-1) detected ...
Drug Interactions | College of Pharmacists of British Columbia
Percutaneous coronary intervention (PCI) and coronary stent insertion has become commonplace and is ubiquitous in the treatment of myocardial infarction. Use of dual antiplatelet therapy or DAPT (ASA plus clopidogrel, ASA plus prasugrel, ASA plus ticagrelor) is critical post PCI and coronary stent insertion to prevent stent thrombosis. The incidence of early stent thrombosis ranges around 1-2% while on DAPT while late stent thrombosis ranges from 0.2-0.6%.1 While the incidence may be low, acute stent thrombosis often presents as a STEMI and is associated with mortality rates of 20-45%. While several factors influences the rates of stent thrombosis, the most common cause of acute stent thrombosis is nonadherence to DAPT.2. ...

Coronary Thrombi Characteristics Vary by Plaque Etiology | Medpage Today
Coronary thrombi in patients who die suddenly are more likely to display signs of healing if they are caused by a plaque erosion rather than a rupture, researchers found.
Plaque Instability Frequently Occurs Days or Weeks Before Occlusive Coronary Thrombosis | Circulation
The pathophysiological model for the occurrence of STEMI describes sudden vessel closure, mostly due to plaque rupture or erosion and subsequent intracoronary occlusive thrombosis at the onset of symptoms.3 Plaque disruption results in exposure of the lipid-rich core of the plaque to the bloodstream, which causes activation and aggregation of platelets. As a result, a luminal thrombus occurs, which prevents normal blood supply to the myocardium. This explains why in many patients with acute transmural myocardial infarction, a platelet-rich, fresh thrombus can be found.12-15 The aspiration of thrombi in 95% of patients in general and fresh thrombi in particular in patients with STEMI in the present study confirms these perspectives and other studies with regard to the pathogenesis of this event. The fact that fresh thrombus could not be identified in all patients may be explained in part by disintegration of the very fragile fresh material by passage through the catheter or in the collection ...

Inflammatory and thrombotic mechanisms in coronary atherosclerosis | Heart
Coronary thrombosis is now widely recognised as a major cause of sudden cardiac death, acute myocardial infarction, and unstable angina pectoris. Inflammation is an important component of the atherosclerotic lesion. In this review we will discuss inflammatory mechanisms in relation to atherosclerosis and clinical coronary thrombosis.. The response to injury hypothesis postulates that endothelial dysfunction represents the initial step of atherogenesis and can be induced by haemodynamic forces, by a variety of vasoactive substances, by mediators from blood cells, and directly from risk factors for atherosclerosis.1 Upon activation, endothelial cells express various cellular adhesion molecules, cytokines, chemokines, and growth factors. Focal arterial inflammatory activity is one of the most prominent characteristics of the atherosclerotic process.2,3 Inflammation is also implicated in the pathogenesis of acute syndromes, as suggested by histological findings in unstable coronary plaques,4-6 ...

[email protected] - AKU Symposium: Very late bare-metal stent Thrombosis: A case report
Stent thrombosis (ST) is an acute thrombotic occlusion in the stented segment of a coronary artery. It is a serious complication that frequently presents as an acute myocardial infarction and/or sudden death. The most recently accepted definition established by the Academic Research Consortium classifies ST as: early (occurring within 30 days), late (30 days to 1 year) or very late (after 1 year). Very late ST has been reported following drug-eluting stent implantation with rates up to 0.6% per year. However, very late ST is unusual after bare-metal stent (BMS) implantation. Here we report a case of patient presenting with ST-elevation myocardial infarction due to very late ST occurring 2 years after BMS implantation.

2006 - Review: Drug-eluting stents for coronary artery disease do not reduce mortality more than bare-metal stents |...
DESs have dramatically decreased the need for coronary artery bypass graft (CABG) surgery and repeated PCI. However, late stent thrombosis is a small but important risk with DESs because it is commonly associated with sudden death or acute MI. The clinical occurrence of stent thrombosis after stent implantation can be defined as acute (, 24 h), subacute (1 to 30 d), late (30 d to 1 y), or very late (, 1 y). The clinical diagnosis of stent thrombosis can be defined as definite if proven angiographically or pathologically, probable if an MI occurs in the distribution of the stented artery, or possible if death is unexplained (1). Risk for subacute stent thrombosis is about 1% for both DESs and BMSs, but risk for very late stent thrombosis continues for at least 4 years with DESs at a rate of 2 to 4 events/1000 patients per year (1−3). The presumed cause is delayed or incomplete endothelialization of the stent struts. The unanswered question is whether the decrease in risk for death and MI ...

Emergence of Plaque Erosion as an Important Clinical Entity | JACC: Cardiovascular Imaging
Most physicians believe that acute coronary syndromes (ACS) are due to coronary artery thrombosis resulting from plaque rupture of a metabolically active inflamed lesion characterized by a thin fibrous cap (thin-cap fibroatheroma [TCFA]), overlying a large necrotic core containing rich concentrations of cholesterol, cholesterol esters, and senescent macrophages (1). Such lesions also demonstrate spotty calcification and neovascularization arising from the vasa vasorum with plaque hemorrhage. Indeed, the chemical structure and morphology of the TCFA is so distinctive that numerous invasive and noninvasive imaging modalities have been developed to search for the mischievous TCFA prior to its becoming unstable, to improve prognostic discrimination and perhaps guide systemic or focal therapies.. However, although pathologic studies have demonstrated that the majority of thrombotic lesions responsible for acute myocardial infarction (AMI) and sudden cardiac death have a ruptured fibrous cap (RFC) ...
Lines of Zahn - Wikipedia
Lines of Zahn are a characteristic of thrombi that appear particularly when formed in the heart or aorta. They have visible and microscopic alternating layers (laminations) of platelets mixed with fibrin, which appear lighter and darker layers of red blood cells. Their presence implies thrombosis at a site of rapid blood flow that happened before death. In veins or smaller arteries, where flow is not as constant, they are less apparent. They are named after German-Swiss pathologist Friedrich Wilhelm Zahn. Atherosclerosis. Lee R, Adlam D, Clelland CA, Channon KM (2012). Lines of Zahn in coronary artery thrombus.

Stent Thrombosis in New-Generation Drug-Eluting Stents in Patients With STEMI Undergoing Primary PCI: A Report From SCAAR -...
This study reports a significantly lower risk of ST during the first year after PCI with both n-DES and o-DES compared with BMS, but a higher risk of very late ST up to 3 years in the o-DES group compared with the BMS group; and a similar risk of very late ST in the n-DES and BMS groups. Although BMS have been proven to be safe in STEMI patients and the improvements of the new stent platforms have reduced restenosis rates, DES are superior in terms of a decrease in restenosis occurrence. This study suggests that n-DES are associated with a low risk of ST even on long-term follow-up and may be the preferred stent type in STEMI patients compared to BMS and o-DES. ...

The study by den Heijer and colleagues is of interest to both interventional cardiologists and internists. The availability of low-profile, flexible, and steerable angioscopic systems has allowed the routine percutaneous application of this technology. Interpretable images can now be obtained in most patients having interventional procedures, although the technique still has important limitations. Problems remain with aiming the angioscope, and a clear imaging field cannot always be obtained. The widespread availability of second-generation interventional technologies, including stents, atherectomy catheters, and local drug delivery systems, give the interventionist a choice of therapies. Precise knowledge of coronary morphology may have an important effect on the decision of which technique to use to treat a given lesion. The study by den Heijer and colleagues suggests that, in a few patients, the angioscopic information was useful to the clinician. These results, however, cannot be ...
