Filter by:The objective is to determine the optimum dose of thrombolytic and duration of the ultrasound procedure (together defined as the APT Procedure) as a treatment for acute submassive pulmonary embolism (PE). Symptomatic submassive PE are participants with acute (less than or equal to [≤]14 days) PE with normal systemic arterial blood pressure (greater than [>] 90 mmHg) and evidence of RV dysfunction (right ventricular to left ventricular diameter ratio, that is; RV/LV ratio greater than or equal to [≥] 0.9). Participants with submassive PE will be randomized to one of four APT treatment groups: ultrasound of 2 and 6 hours (hrs) with r-tPA 2 milligrams (mg)/hr/catheter and ultrasound 4 and 6 hours with r-tPA, 1 mg/hr/catheter. On 08 June 2016, randomization into treatment group 4 (APT/6 hours-r-tPA/2 mg/hr/catheter) was closed following a reported intracranial hemorrhage (ICH) and death in a study participant in this arm.
Differences in efficacy and safety between new oral anticoagulants (NOAC) and vitamin K antagonist (VKA) in real practice remain uncertain. The few existing ambulatory studies did not answer all NOAC specific issues, such as prescription habits and motives, patients characteristics, biological monitoring, as well as the occurrence of major and minor thromboembolic events, especially in France where warfarin is less frequently prescribed. Therefore, in order to describe clinical and follow up characteristics of patients receiving oral anticoagulants, the investigators will set up a national prospective cohort to compare the occurrence of thromboembolic events between VKA and NOAC in primary care.
The objective of this study is to determine the rate of radial artery occlusion and vascular access site complications following transradial angiogram using a new Terumo (Tokyo, Japan) Glidesheath Slender, in comparison with the currently used 6 French (6 Fr.) radial sheath.
The investigators will conduct a prospective observational cohort study to investigate factors that influence contraceptive method utilization among women with medical conditions. The investigators will also investigate how women with medical conditions access to contraception and family planning fellowship trained specialist. After the baseline questionnaire, there be a 3 month and 6 month follow up questionnaire to investigate continuation and satisfaction with the contraceptive method. This study is unique because it will allow us to explore doing collaborative family planning research at the multiple UC medical campuses.
The proposed PIVOTAL study will examine a panel of platelet/coagulation activity markers during the perioperative period. The goal is to develop a clinically useful assessment of platelet/coagulation activity for risk stratification that may ultimately serve as a target for therapeutic intervention. This study will enroll 200 patients with peripheral artery disease undergoing vascular surgery. PIVOTAL is funded by American Heart Association and is scheduled to begin enrollment in July 2013 for approximately two years.
The objective of this study is to compare the efficacy, safety of DU-176b 30mg or DU-176b 15mg versus enoxaparin sodium for the prevention of venous thromboembolism in patients after elective total hip arthroplasty.
The Registry involves the collection of information for research and educational purposes only on the use of AngioJet in the peripheral vascular system.
The purpose of this quasi-experiment study, which could also be classified as a prospective observational intervention study, is to assess the impact of cytochrome P450 2C9 (CYP 2C9) and vitamin K epoxide reductase complex, subunit 1 (VKORC1) testing within a primary patient care setting.
The purpose of this study is to determine different risk factors of thromboembolic disease. Different points will be studied 1. do different types of thromboembolic disease (distal Deep Vein Thrombosis (DVT), proximal DVT, Pulmonary Embolism (PE) and DVT, PE without DVT) have the same clinical significance (risk factors and prognosis) ? 2. Is it necessary to obtain a detailed history of thromboembolic disease ? 3. Do older patients have particular risk factors ? 4. Do preventive treatments modify the level of risk factors and the clinical signs of thromboembolic disease ? 5. Do predictive clinical scores have the same performance for both in and outpatients ? 6. Can patients with a potential high level of thromboembolic risk (surgery, pregnancy) but no clinical thromboembolic symptoms, develop a low risk ? 7. The evolution of the disease in patients with negative or positive Venous ThromboEmbolism (VTE) exploratory tests.
The purpose of this study is to test the hypothesis that using three different techniques to anastomose coronary grafts to the aorta: partial occlusion, single cross clamp, or using the Heartstring anastomotic device, will change the amount of gas and solid microemboli as detected by the EmbodopR transcranial Doppler (TCD) system and consequently the neurocognitive performance of patients after coronary bypass operation.
