Restarting Oral Anticoagulation in Patients With Atrial Fibrillation After an Intracranial Hemorrhage

Atrial fibrillation is the most common sustained cardiac arrhythmia in the general population. In western countries with aging populations, atrial fibrillation poses a significant health concern, as it is associated with a high risk of thromboembolism, stroke, congestive heart failure, and myocardial infarction. Thrombi are generated in the left atrial appendage, and subsequent embolism into the cerebral circulation is a major cause of ischemic stroke. Therefore, patients have a lifetime risk of stroke, and those at high risk, defined as a CHA2DS2-VASc2 (congestive heart failure, hypertension, age>75 years, diabetes mellitus, stroke/transient ischemic attack/thromboembolism, vascular disease, age 65-74 yrs, sex category) ≥2, are usually placed on oral anticoagulants. Unfortunately, long-term anticoagulation poses bleeding risks, of which intracranial hemorrhage (ICH) is the most feared and deadly complication. In patients who survive an ICH, the question of oral anticoagulation resumption arises. It is a therapeutic dilemma in which clinicians must decide how to manage the risk of thromboembolism versus recurrent hemorrhage. Although there is a substantial amount of retrospective data on the topic of resumption of anticoagulation, there are, at this time, no randomized controlled trials addressing the issue. We therefore sought to address ICH risk and management, summarize high quality existing evidence on restarting oral anticoagulation, and suggest an approach to cli...

Authors: Bergland OU, Søraas CL, Larstorp ACK, Halvorsen LV, Hjørnholm U, Hoffman P, Høieggen A, Fadl Elmula FEM Abstract PURPOSE: The blood pressure (BP) lowering effect of renal sympathetic denervation (RDN) in treatment-resistant hypertension shows variation amongst the existing randomised studies. The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

Authors: Zhao N, Xiang Q, Liu Z, Zhao X, Cui Y Abstract INTRODUCTION: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. AREAS COVERED: We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion exclusion criteria, safety and pharmacodynamic indexes were reviewed. EXPERT ...

Authors: Siamashvili M, Davis S Abstract INTRODUCTION: Bromocriptine mesylate quick release (QR) is a dopamine D2 receptor agonist and is the only oral, primarily centrally acting drug that can be used for the treatment of adults with type 2 diabetes. AREAS COVERED: The authors describe current recommendations on the use of bromocriptine mesylate QR. Major efficacy and safety parameters of the late phase trials, including The Cycloset Safety Trial, have been identified and presented. EXPERT OPINION: Efficacy of bromocriptine mesylate QR monotherapy appears to be low but is compensated by favorable safety pr...
