Active clinical trials for "Thrombosis"

Direct oral anticoagulants (DOACs) are now recommended as a first-line option in cancer patients with venous thromboembolism or atrial fibrillation. However, current international clinical practice guidelines and product inserts suggest caution and/or avoidance in using DOACs in case of potential potential drug-drug interactions (DDI), including DDI with anticancer therapies. Indeed, potential important DDIs can affect the efficacy and safety of DOACs and/or anticancer therapies and/or other interfering medications in these patients. Data about the pharmacokinetics (PK) of DOACs in cancer patients are scarce. By using a PK approach, this study aims : to describe the PK profile of rivaroxaban and apixaban in adult cancer patients with venous thromboembolism or atrial fibrillation from a real-world setting to identify factors (age, weight, renal function, co-morbidities, etc) influencing the PK profile of rivaroxaban and apixaban in adult cancer with venous thromboembolism or atrial fibrillation from a real-world setting.

A Multicenter Registry of Endovascular Treatment for Acute Ischemic Stroke.

The purpose of the COMPLEX Registry is to prospectively and retrospectively collect baseline, clinical and procedural data of patients who have undergone PCI or CABG for complex and/ or calcified chronic CAD, irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. The outcomes will be compared in different clinical subgroups (e.g. PCI vs. CABG). The impact of current PCI techniques/ devices, but also CABG strategies in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.

This is a parallel assigned, open-label, perspective trial studying the safety and efficacy of intensity-modulated radiotherapy (IMRT) combined with PD-1 Blockade and Lenvatinib for Hepatocellular Carcinoma (HCC) with Vp3 Portal Vein Tumor Thrombus (PVTT, Japanese Liver Cancer Study Group classification) before liver transplantation.

Consenting patients with end-stage heart failure that are implanted with/candidates for implant of a short-term/durable mechanical circulatory support device (e.g.: percutaneous microaxial pumps (Impella), extracorporeal membrane oxygenator (ECMO), Ventricular Assist Device (VAD) will be enrolled in the study. Aim of the study is to evaluate the patients' haemostatic and coagulation profile, how it interacts with the support device as well as the effect of antithrombotic drugs. From these data, it will be possible to derive the mechanisms triggering post-implant thromboembolic/hemorrhagic complications and to identify potential therapeutic targets.

This study is an extension of a planned quality improvement project that aims to promote standard of care by increasing the use of evidence-based clinical decision rules amongst emergency medicine providers in the University of Utah Emergency Department. Patient-specific information from the EHR will be used to recommend the use of relevant clinical decision rules to emergency medicine providers at the point-of-care. These recommendations will be in the form of non-interruptive alerts with one-click access to the suggested decision rules through the MDCalc Connect EHR add-on application. Specific aims of the study are to determine if 1) patient-specific non-interruptive alerts increase the use of clinical decision rules amongst emergency medicine providers and 2) an increase in the use of clinical decision rules affects provider ordering habits.

Pulmonary embolism impacts over 1 in 1000 adults annually and is the third leading cause of cardiovascular death after heart attack and stroke. The consequence of each PE is widely variable. Physiologically, the morbidity and mortality of PE is ultimately caused by failure of the right ventricle. The acute rise in pulmonary vascular resistance caused by a PE can overwhelm the right ventricle, resulting in a drop in cardiac output and death from failure of the heart to provide vital perfusion. Despite the importance of stroke volume and cardiac output in the current understanding of PE mortality, they are notably absent from risk stratification scores because they historically could only be measured invasively. Novel non-invasive methods of estimating stroke volume and associated cardiac output have the potential to revolutionize PE risk stratification and care. Non-invasive blood pressure (NIBP) monitors can even measure stroke volume beat to beat, allowing for continuous evaluation of cardiac function. NIBP systems are typically composed of a finger cuff with an inflatable bladder, pressure sensors, and light sensors. An arterial pulse contour is formed using the volume clamp method of blood pressure measurement combined with calibration and brachial pressure reconstruction algorithms. The stroke volume with each heart beat can be estimated as the area under the systolic portion of the blood pressure curve divided by the afterload. NIBP monitors may improve clinical care of PE because they allow for assessment of dynamic cardiac changes in real time. Detection of worsening stroke volume in acute PE could inform providers of impending cardiac collapse, and improvement of stroke volume may function as a positive prognostic factor or marker of therapeutic success. Use of NIBP monitors during acute PE to identify clinically significant changes in cardiac function may advance both PE prognostication and management. Our clinical study proposes to monitor hemodynamic parameters including stroke volume in patients with acute pulmonary embolism using non-invasive blood pressure monitors. The relationship between hemodynamic parameters and PE outcomes will be assessed, as well as the changes in hemodynamic parameters with PE intervention. To our knowledge, interval monitoring of stroke volume during acute PE with NIBP monitors has never been reported before.

At menopausal transition, the risk of cardiovascular diseases increases. This is partly due to aging, but largely also the loss of estrogen, which has many positive effects on the circulation and protects against cardiovascular diseases. It has been suggested that the loss of estrogen may have a negative impact on the otherwise well-documented health promoting effects of exercise training, and that the time after menopause may be crucial for the effect of exercise training on the vascular function, and therefore also for the risk of thrombosis. Literature regarding the effect of exercise training on the risk of thrombosis is limited, and especially in women. The purpose of the present study is to investigate whether the same effects of exercise training in relation to thrombosis is achieved if the exercise is initiated early compared to late after menopause. The aim is to provide knowledge-based recommendations regarding exercise. Teams sports will be used as the training intervention, because team sports benefits physical health and also includes a social element.

This is a prospective cohort study of 30 patients who are 8-21 years of age with venous thromboembolism (VTE)- either lower extremity deep venous thrombosis (DVT) or pulmonary embolism (PE).

The primary objective of this study is to assess the safety and tolerability of SHR-2004 injection in healthy subjects. In addition, this study will provide information on pharmacokinetics and pharmacodynamics of SHR-2004 injection in healthy subjects.
