Filter by:Bleeding occurring during percutaneous coronary interventions (PCI has now emerged as one of the most common complication of PCI and adversely affect in-hospital, short- and long-term outcome.As bivalirudin proved its effectiveness in decreasing haemorrhagic events during PCI, its administration may be advocated in subjects deemed at high risk of bleeding.Objective of the present trial is to compare the safety and effectiveness of procedural use of bivalirudin in comparison to unfractionated heparin (UFH) in patients undergoing PCI deemed at high risk of procedural bleeding.
The optimal medical strategy for prevention of thromboembolic events after bioprosthetic aorta valve replacement (BAVR) remains controversial. The aim of this trial was to compare warfarin therapy (target INR of 2.0 to 3.0) against aspirin 150mg daily as antithrombotic therapy for the first three months after BAVR with or without concomitant coronary artery bypass grafting (CABG). The aim was to evaluate thromboembolic complications, bleeding complications and death.
The purpose of the study is to examine how well three months preceding use of Cerazette progestin only pill predicts the bleeding pattern during following Nexplanon implant use.
Research questions: 1. What is the absolute risk reduction for in-hospital major adverse cardiac events (MACE) associated with the use of dual anti-platelet therapy as compared with aspirin alone in this population? 2. What is the absolute risk increase for clinically significant bleeding during the same period associated with the use of dual anti-platelet therapy as compared with aspirin alone in this population? In brief the design of the study is as follows: - We will study patients undergoing non-cardiac surgery within four years of coronary stenting. - We will record the anti-platelet agents taken by patients before, during and after surgery. - We will record cardiac and bleeding events that occur whilst the patient is in hospital. - We will use the statistical technique of propensity scoring to match patients who have similar risk factors and who received different anti-platelet regimens. - We will compare the incidence of cardiac events and bleeding in the matched groups.
The objective of this trial is to evaluate the safety and efficacy of ExAblate for the treatment of uterine fibroids. Women, seeking treatment for symptomatic uterine leiomyomata will be eligible for the study.Women who agree to participate will sign an informed consent and will be randomized to ExAblate treatment or myomectomy. All patients will be followed through the 36 month visit. Follow-up visits/telephone calls will be completed at 1 week, 2 weeks, 6 weeks, 3 months, 6, 12, 18, 24 and 36 months post treatment. Patients will be evaluated by assessing their overall physical and mental health as well as for device/procedure related adverse events.
Pregnancy is associated with an overall 5-10 fold increased risk of venous thromboembolism (VTE). VTE remains the most common cause of maternal death in the developed world. It is up to 10 times more common in pregnant women than non-pregnant women of comparable age. More than a third of pregnancy-related VTE occurs during the six weeks after delivery. When compared with vaginal delivery, cesarean delivery further increases the risk of pregnancy associated VTE by three-fold.
The objective of the study is to test the hypothesis whether or not autologous stored platelets are able to offset the antiplatelet effect of aspirin and clopidogrel as assessed by state-of-the-art platelet function assays.
In the last years, important advances have been done in the treatment and prevention of esophageal variceal bleeding. Experts agree that the combination of pharmacological and endoscopic therapy should be the first line therapy in the acute bleeding episode; whereas TIPS (transjugular intrahepatic portosystemic shunt) is considered a rescue therapy. Nevertheless, some patients would require different therapies to act as a "bridge" until definitive therapy can be instituted. Balloon tamponade (using the Sengstaken tube) represents, up to now, the most widely used temporary "bridge" to TIPS. However, balloon tamponade is associated with a high incidence of serious adverse events. Recently, the use of self-expanding metal stents have been introduced in the treatment of acute variceal bleeding showing a very high hemostatic efficacy with no adverse events. The present study is directed to compare the efficacy free of adverse events and mortality of self-expanding metal stents vs balloon tamponade in patients with variceal bleeding refractory to medical and endoscopic therapy.
Many patients undergo cardiac surgery without proper suspension of antiaggregation drugs. This is blamed to increase dramatically bleeding and use of allogenic blood transfusions. The investigators test the hypothesis that routine use of aggregometry could show antiaggregated patient and lead to normalization of platelet function via administration of Desmopressin thus limiting bleeding and transfusions.
The objective is to describe and quantify levels of platelet reactivity in three different cohorts of patients taking thienopyridine: patients who report nuisance bleeding, patients who report alarming bleeding, and patients who report no nuisance or alarming bleeding. The investigators hypothesize that patients with nuisance or alarming bleeding events on maintenance thienopyridine therapy will have lower levels of platelet reactivity than patients without nuisance or alarming bleeding on thienopyridine therapy.
