Thrombus formation is critical in the pathogenesis of coronary artery disease, and faster clotting speed as measured by activated partial thromboplastin time (aPTT) has been associated with recurrent cardiovascular events in acute coronary syndrome (ACS) patients [2]. Only two small studies have investigated the association of PTSD with markers of coagulation. One case–control study (N = 14 PTS...

discussions as one ich patient whose pt and aptt suggest a coagulation disorder secondary to vitamin k deficiency or coagulation factor deficiency, unresponsiveness to vitamin k therapy should be useful to take fx deficiency into consideration. background inborn factor x deficiency (fxd) is a very rare (1: 500,000) hereditary coagulation disorder, which is characterized by clinical manifestatio...

BACKGROUND Thromboelastometry (ROTEM(®)) might be useful to detect intraoperative coagulation disorders early in major paediatric surgery. This observational trial compares this technique to standard coagulation tests. METHODS Intraoperative blood sampling was obtained in children undergoing elective major surgery. At each time point, standard coagulation tests [activated partial thromboplast...

BACKGROUND In Phase I evaluation of CT-2103 (paclitaxel poliglumex), prolongation of prothrombin time (PT) and activated thromboplastin time (aPTT) was observed, without clinical consequence, with doses 1.3-1.5 times higher than the current clinical dose of 175 mg/m(2). This Phase I, open-label, nonrandomized pilot study was performed to study the effect of the standard dose regimen on blood co...

Prothrombin time (PT) and activated partial thromboplastin time (aPTT) are common laboratory tests that are useful in the diagnosis of coagulation disorders and monitoring anticoagulant therapy. Recent expansions in the outreach laboratory services at our institution prompted us to investigate the shipping limitations for some tests, including PT and aPTT. Although we followed NCCLS guidelines ...

Activated partial thromboplastin times (APTT) for monitoring heparin therapy for venous thromboembolism tended to be inappropriately short if blood was collected in commercially available evacuated glass tubes. Five types of evacuated tubes marketed under the trade names Vacutainer and Venoject were examined. The APTT of heparinized blood collected in these tubes correlated poorly (r = 0.04 to ...

We evaluated the clinical usefulness of a recently developed semi-automated one-step chromogenic equivalent of activated partial thromboplastin time (APTT; Behring). This simple test is easily adaptable for automation. Generally, the results with this chromogenic one-step APTT were at least as precise as those obtained with comparative coagulometric methods. The chromogenic one-step APTT showed...

Thrombotic disorders increase the risk of cardiovascular/cerebrovascular complications and represent a major health problem worldwide. Anticoagulants are extensively used in treatment of these disorders. Vitamin K antagonists, like Warfarin, are frequently used in medication. Vascular calcification (VC) is a significant side-effect of vitamin K antagonists especially Warfarin. There is an urgen...

Aim:The aim of this study was to examine the effects use SSRI by patients in different gynecological operations, through an evaluation operation type, bleeding amount, requirement for blood and amount transfused. 
 Material Methods: A retrospective made who underwent surgery. Patients were taking not compared respect preoperative postoperative hemoglobin, hematocrit, platelet count, activa...

The in vivo antithrombotic properties of human plasma activated protein C (APC), a natural anticoagulant enzyme, were investigated in a baboon model of thrombus formation on prosthetic vascular grafts. Infusion of 0.25 to 1.1 mg/kg/h purified, human, APC inhibited blood clotting, as measured by the activated partial thromboplastin time (APTT), and reduced vascular graft platelet deposition by 4...
