Filter by:Rationale: Heart attacks are a major cause of death and result from coronary blood clots that require acute coronary intervention and antithrombotic drugs to restore blood flow and prevent new heart attacks. Over time, more potent antithrombotic drugs have been introduced like prasugrel and ticagrelor. These drugs have replaced the older drug, clopidogrel, as approximately 30% of patients are low-responders to clopidogrel for genetic reasons. However, the newer drugs introduce a significant risk of serious bleeding. Aim: The aim of this trial is to assess a reduced antithrombotic strategy for high bleeding risk patients with heart attacks to reduce bleeding safely. Hypothesis: Significantly reduced bleeding with a similar preventive effect are expected. Design: The Dan-DAPT trial include high bleeding risk patients with heart attacks from Danish hospitals (Rigshospitalet, Aarhus, Odense, Aalborg, Roskilde, and Gentofte hospital) and randomize them to standard-of-care or shorter and individualized antithrombotic therapy based on responsiveness to clopidogrel after genetic testing.
Diabetic retinopathy (DR) is one of the main complications in diabetes, the proliferative diabetic retinopathy (PDR) is the most important one of the reasons leading to decreased vision, PDR is the stage of clinical intervention. Pars plana vitrectomy (PPV) is an effective treatment for PDR, while vitreous haemorrhage (VH) is a common complication after PPV, with incidence ranging from 11.8% to 75%, and is the main cause of reoperation. Anti-Vascular endothelial growth factor (VEGF) therapy for vitreous hemorrhage can inhibit neovascularization and prevent recurrent vitreous haemorrhage after absorption. Previous studies have found that anti-VEGF is a safe and effective treatment for postoperative recurrent VH. In consideration of the psychological and economic factor of patients, this study intends to observe the effectiveness of single vitreous injection of Ranibizumab in the treatment of postoperative recurrent VH on the basis of previous clinical work. Compare the visual acuity, macular thickness, VH recurrence and patient satisfaction between the Ranibizumab group and the PPV group by randomized grouping.To observe the effective rate and clearance time of recurrent VH after Ranibizumab treatment and whether it can effectively reduce the rate of PPV. To provide clinical guidance for the precise treatment of PDR patients, the treatment of PDR patients has important clinical significance and social and economic significance.
To determine the effectiveness of using two medications simultaneously versus one medication, as is standard of care, in preventing early postpartum hemorrhage. There have been studies that looked at giving two medications and that there were reduced odds of postpartum hemorrhage. Specific Aim 1: Determine if double simultaneous uterotonic agent regimen (misoprostol and oxytocin) is superior to single agent (oxytocin only) in reducing postpartum hemorrhage. Specific Aim 2: Determine any potential side effects of a double simultaneous uterotonic agentregimen (misoprostol and oxytocin) versus a single agent (oxytocin only).
the study aims to evaluate the efficacy of intramyometrial Terlipressin injection versus intramyometrial Carbetocin injection on hemoglobin level in women undergoing abdominal myomectomy. Moreover, to evaluate their efficacy in decreasing blood loss on operative time and to describe the injection sequelae for the same population. This clinical study will be conducted in compliance with the clinical study protocol and applicable regulatory requirements.
Randomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (TLF) at 12 months in high bleeding risk patients who underwent elective coronary percutaneous intervention with a zotarolimus eluting stent versus a sirolimus eluting stent and short Dual Antiplatelet Therapy (DAPT).
The purpose of this pilot study is to evaluate the safety of stromal vascular fraction (SVF) therapy in patients with spontaneous intracerebral hemorrhage (SICH).
Intra-operative blood loss of huge meningioma resection patients on average was over 1000ml. Intra-operative massive hemorrhage was associated with longer hospital of stay, higher expense, and higher mortality. Previous studies indicated intra-operative tranexamic acid infusion would decrease blood loss for cardiac, trauma and obstetric procedures. However, limited researches focusing on the effect of tranexamic acid in neurosurgery population, with heterogenous pathologies. The purpose of this study was to investigate the effect of tranexamic acid on intra-operative blood loss in patients undergoing huge meningioma resection.
Gastrointestinal Emergency Surgery: Evaluation of Morbidity and Mortality
The outcome of subarchnoid hemorrhage depends on the severity of the bleeding and the development of secondary neurologic deficits caused by cerebral vasospasm. The primary endpoint is a comparison of renin angiotensin system (RAS) parameters (plasma concentrations of Angiotensin [Ang] I, Ang II, Ang 1-7, and Ang 1-5, angiotensin metabolite based markers of RAS enzyme activities as well as active ACE and ACE2 concentrations in plasma and CSF) between patients with and without vasospasm, mechanical ventilation, antihypertensive therapy with a RAS modifying drug and low versus high Hunt and Hess grade of subarachnoid hemorrhage.
DCB-HBR trial is prospective, multi-center, open-label, randomized controlled, noninferiority trial. The aim of the study is to compare clinical outcomes of drug-coated balloon (DCB) with drug-eluting stent (DES) for treatment of de-novo coronary lesion under intravascular imaging-guided optimization in patients with high bleeding risk (HBR).
