Acute pulmonary embolism (PE) is a major public health problem. It is the third most common cause of death in hospitalized patients. In the United States, there are up to 600,000 cases diagnosed per year with 100,000-180,000 acute PE-related deaths. Common risk factors include underlying genetic conditions, acquired conditions, and acquired hypercoagulable states. Acute PE increases the pulmonary vascular resistance and the load on the right ventricle (RV). Increased RV loading causes compensatory RV dilation, impaired contractility, tachycardia, and sympathetic activation...

Mondor's disease (MD) is a rare disease that manifests with a palpable cord-like induration on the body surface. In general, MD is a self-limited, benign thrombophlebitis that resolves in four to eight weeks without any specific treatment. Cases of MD can be roughly categorized into three different groups based on the site of the lesion as follows: original MD of the anterolateral thoracoabdominal wall, penile MD with dorsum and dorsolateral aspects of the penis, and axillary web syndrome with mid-upper arm after axillary surgery...

INTRODUCTION: In patients with a hypercoagulable state, such as patients with pulmonary embolism and/or Budd-Chiari syndrome, the complications from multiple gene mutations are more numerous than those from a single mutation. The authors present a woman with no major prior medical history who presented with pulmonary embolism and Budd-Chiari syndrome; this enigmatic co-occurrence has never been solely reported without underlying aetiology in a patient without prior medical conditions...

Background: Diabetes mellitus is a very rampant metabolic disorder, particularly type II. It has many complications such as the septic foot. Diabetic septic foot (DSF) patients are at high risk for coagulation abnormalities as well as surgical hazards. Owing to the potential sequelae of coagulation and vascular abnormalities, this work aimed at studying the hemostatic state and platelet indices in diabetes type II patients with septic foot. Methods: A case-control study was conducted during the period from July to September 2017 at Dr...

The incidence of venous thromboembolism (VTE) in adult patients with sickle cell disease (SCD) is high. However, overlapping features between the clinical presentation of VTE and SCD complications and a low index of suspicion for thrombosis can influence patient management decisions. VTE in SCD can therefore present management challenges to the clinical hematologist. Herein, we present three distinct clinical vignettes that are representative of our clinical practice with SCD patients. These vignettes are discussed with specific reference to the hypercoagulable state in SCD patients, recent VTE diagnosis and anticoagulant therapy guidelines from the general population, and evaluation of the risk of bleeding as a result of long term exposure to anticoagulant therapy...

The antiphospholipid antibody syndrome (APS) is defined by a state of hypercoagulability secondary to an autoimmune disorder. There are evidences that approximately 2.8-5.5% of cases of acute myocardial infarction (AMI) in young individuals are secondary to APS. In this case report, three coronary artery thromboses occurring within a short period are described. Initially, there was an ST-segment elevation (STEMI) in the presence of coronary artery disease (CAD), with the vessel being treated with stent implantation...

Extracellular vesicles (EVs) act as transporters that carry regulatory molecules between cells in physiologic and pathologic states; therefore, they play a crucial role in thrombosis, inflammation, angiogenesis, vascular dysfunction and other processes that affect the course of hematologic diseases. Within the tumor microenvironment, for example the leukemic bone marrow, EVs-mediated signaling may direct the activities of surrounding cells and act as a positive feedback loop that contributes to cancer progression...

Although cancer is associated with coagulation disorders, it is still unclear how the combination of tumour cell and host factors enhance the hypercoagulable state of cancer patients. Emerging evidence points to a central role for tumour endosomal and plasma-membrane derived vesicular components in the pathogenesis of cancer-related thrombosis. In particular, tumour cell membranes and extracellular vesicles (EV) harbour lipids and proteinaceous coagulation factors able to initiate multiple points within the coagulation matrix...

The higher incidence of arterial and venous events is well established in patients with rheumatoid arthritis (RA). Our aim here was to investigate whether there is a prothrombotic state in RA patients by using rotational thromboelastometry (ROTEM) method and to demonstrate whether the disease variables play a role in this process. A total of 85 patients who met the 2010 RA classification criteria were consecutively included in the study. The patients with RA who have been using antiaggregant, anticoagulant, or nonsteroidal anti-inflammatory drugs (NSAIDs) and had a history of arterial or venous thromboembolism were excluded from the study...

Patients with bladder cancer are at high risk of developing both venous and arterial thromboembolic events. Factors that contribute to this phenomenon include the hypercoagulable state induced by the malignancy itself, medical comorbidities that are common in this predominantly elderly patient population as well as treatments such as prolonged pelvic surgery and cisplatin-based chemotherapy. While formal guidelines address prevention of venous thromboembolism in patients undergoing radical cystectomy, consensus regarding the role of pharmacologic prophylaxis in patients with bladder cancer being treated with chemotherapy, either with neoadjuvant or adjuvant intent in conjunction with radical cystectomy, as part of bladder preservation protocols or for metastatic disease, has proved elusive...

Exercise is protective against cardiovascular disease, but can also provoke sudden cardiac death, a phenomenon referred to as "the exercise paradox." Extreme exertion is known to induce a rebalanced hemostatic state by causing hypercoagulability and concomitantly enhanced fibrinolysis. Over the past decade, novel techniques for quantifying hemostasis have been introduced, which may provide new insights into this process. This review summarizes recent literature on the effect of extreme exertion of both short and long duration on coagulation, fibrinolysis, and recovery of hemostatic balance...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is an adverse reaction to heparin characterized by thrombocytopenia and thrombotic complications. HIT is caused by pathogenic antibodies that bind to complexes of platelet factor 4 and heparin (PF4/heparin) leading to platelet activation and inducing a hypercoagulable state. Previous studies have shown immunity to PF4/heparin occurs early in life even before heparin exposure; however, the immunogenesis of HIT is not well characterized...

Anxiety, a normal response to stressful situations, is characterized by increased levels of factor VIII, fibrinogen, and von Willebrand factor, and by enhanced platelet aggregability. One would expect acute anxiety to be a prothrombotic state, but since acute mental stress induces tissue plasminogen activator (tPA) release from endothelial and chromaffin cells, fibrinolysis counteracts procoagulant stimuli. It could be said that procoagulant changes accompanying the fight-or-flight response reduce the risk of bleeding in case of potential injuries, while activation of fibrinolysis counteracts activation of hemostasis to prevent intravascular thrombus formation before injuries occur...

Type 2 diabetes mellitus (T2DM) promotes a high oxidative stress and hypercoagulable state that drives microvascular injury and multiple-organ abnormality. Elevated thrombin activity underlies T2DM-linked endothelial dysfunction, but the mechanistic links between T2DM/oxidative stress axis and thrombin-associated endothelial pathologies are incompletely understood. In this work, immunohistochemical studies and quantitative analysis using isolated endothelial cells (ECs) identified accumulated Kru¨ppel-like family of transcription factor 14 (KLF14) deposits in ECs from multiple organs as distinct features of T2DM mice...

A 72-year-old man was admitted to our hospital because of right upper limb monoplegia 8 hours after the initial intravitreal injection of aflibercept, which is an inhibitor of vascular endothelial growth factor. Magnetic resonance diffusion-weighted images showed recent ischemic lesions in the left corona radiata and the right superior frontal gyrus. Laboratory findings showed mild hyperfibrinolysis. A patent foramen ovale was diagnosed on transesophageal echocardiography; however, lower-extremity ultrasonography did not detect deep vein thrombosis...

Inferior vena cava (IVC) thrombosis is very rare, particularly in the absence of an apparent congenital caval abnormality or hypercoagulable state. We herein report an unusual case of a healthy and active 62-year-old male bodybuilder with a mass-like IVC thrombus. We placed an IVC filter and began treatment with rivaroxaban. The patient recovered successfully, and the IVC thrombus completely disappeared three months later. This case suggested that extrinsic compression of IVC by a tightened weightlifting belt around the abdomen is a triggering factor of IVC thrombosis, and rivaroxaban, a new oral anticoagulant, may be a useful option for treatment...

BACKGROUND: Ehrlichia canis infection in dogs can cause thrombocytopenia and clinical evidence of bleeding. It is unknown why some dogs show signs of bleeding whereas others do not despite clinically relevant thrombocytopenia. HYPOTHESIS/OBJECTIVES: Activated platelets, decreased fibrinolysis or both mitigate bleeding tendency. Assess standard hemostatic variables, platelet dynamics, and specialized coagulation testing in dogs experimentally infected with E. canis to evaluate this clinical discrepancy...

REVIEW
Emily S Lau, Nandita S Scott
With improving reproductive assistive technologies, advancing maternal age, and improved survival of patients with congenital heart disease, valvular heart disease has become an important cause of morbidity and mortality in pregnant women. In general, stenotic lesions, even those in the moderate range, are poorly tolerated in the face of hemodynamic changes of pregnancy. Regurgitant lesions, however, fare better due to the physiologic afterload reduction that occurs. Intervention on regurgitant valve preconception follows the same principles as a non-pregnant population...

Hypercoagulability in ST-segment elevation myocardial infarction (STEMI) as related to long-term clinical outcome is not clarified. We aimed to investigate whether prothrombin fragment 1+2 (F1+2), d-dimer, and endogenous thrombin potential (ETP) measured in the acute phase of STEMI were associated with outcome. Blood samples were drawn median 24 hours after symptom onset in 987 patients with STEMI. Median follow-up time was 4.6 years. Primary outcome was a composite of all-cause mortality, reinfarction, stroke, unscheduled revascularization, or rehospitalization for heart failure; secondary outcome was total mortality...
