[Resumption of antithrombotic treatment after an intracerebral haemorrhage]

There is no evidence from randomised clinical trials with regard to the question if and when to resume antithrombotic medication in patients who have suffered an intracerebral haemorrhage and in whom medication continues to be indicated. It is unknown whether new oral anticoagulants are more suitable than vitamin K antagonists in this group of patients. Oral anticoagulants should probably not be resumed in patients with a lobar intracerebral haemorrhage caused by cerebral amyloid angiopathy. They can be considered in patients with a haemorrhage in subcortical regions of the brain, the brain stem or the cerebellum, provided that blood pressure levels are under control. Depending on the risk of a cardiac embolus, antithrombotic medication can be resumed from 1 to 10 weeks after the intracerebral haemorrhage. In patients with atrial fibrillation this risk can be calculated using the CHA2DS2-VASc score. In patients with a cardiac indication for antithrombotic medication the decision whether or not to resume medication should be made by a cardiologist and a neurologist in collaboration

The Changing Landscape for Stroke Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

open14sifunding from Boehringer Ingelheim.GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non-vitamin K antagonist oral anticoagulant (NOAC), became available. OBJECTIVES: This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. METHODS: During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients' baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. RESULTS: Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score ≥2; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc = 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N = 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. CONCLUSIONS: The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

Quality of life after catheter and minimally invasive surgical ablation of paroxysmal and early persistent atrial fibrillation: results from the SCALAF trial

Contains fulltext : 229201.pdf (Publisher’s version ) (Closed access)AIMS: In the SCALAF trial, catheter-based pulmonary vein isolation (PVI) was as effective in long-term prevention of atrial fibrillation (AF) as minimally invasive thoracoscopic PVI and left atrial appendage ligation (MIPI). Catheter ablation (CA) resulted in significantly less major complications as compare to MIPI. We report quality of life (QOL) outcome in these patients. METHODS: In this study, 52 patients with symptomatic paroxysmal or early persistent AF were randomized to either MIPI or CA. QOL was assessed at baseline, 3, 6, and 12 months follow-up using the SF-36 Health Survey Questionnaire. AF-related symptoms were quantified at each follow-up visit using the European Heart Rhythm Association (EHRA) score. RESULTS: Median age was 57 years and 78% was male. Paroxysmal AF was present in 74%. At 3 months follow-up, physical role limitations (88.2 +/- 29.5; versus 40.9 +/- 44.0; P = 0.001, respectively) and bodily pain scores (95.5 +/- 8.7; versus 76.0 +/- 27.8; P = 0.021, respectively) were significantly higher after CA compared to MIPI, indicating less limitation in daily activity caused by physical problems and less pain after CA than after MIPI. AF symptoms assessed by the EHRA scores improved significantly at 3, 6, 12, and 24 months compared to baseline in both treatment groups (P < 0.001), with no significant differences between treatment groups. CONCLUSIONS: CA and MIPI ablation of AF both resulted in an improvement in several QOL measurements, although CA resulted in significantly less physical problems and bodily pain 3 months after treatment compared to MIPI.

Randomized Controlled Trial of Surgical Versus Catheter Ablation for Paroxysmal and Early Persistent Atrial Fibrillation

Contains fulltext : 200354.pdf (Publisher’s version ) (Closed access)BACKGROUND: Current guidelines recommend both percutaneous catheter ablation (CA) and surgical ablation in the treatment of atrial fibrillation, with different levels of evidence. No direct comparison has been made between minimally invasive thoracoscopic pulmonary vein isolation with left atrial appendage ligation (surgical MIPI) versus percutaneous CA comprising of pulmonary vein isolation as primary treatment of atrial fibrillation. We, therefore, conducted a randomized controlled trial comparing the safety and efficacy of these 2 treatment modalities. METHODS: Eighty patients were enrolled in the study and underwent implantable loop recorder implantation. Twenty-eight patients did not reach randomization criteria. A total of 52 patients with symptomatic paroxysmal or early persistent atrial fibrillation were randomized, 26 to CA and 26 to surgical MIPI. The primary end point was defined as freedom of atrial tachyarrhythmias, without the use of antiarrhythmic drugs. The safety end point was freedom of complications. RESULTS: Median age was 57 years (range, 37-75), and 78% were men. Paroxysmal atrial fibrillation was present in 74%. Follow-up duration was >/=2 years in all patients. CA was noninferior to MIPI in terms of single-procedure arrhythmia-free survival after 2 years of follow-up (56.0% versus 29.2%; HR, 0.56; 95% CI, 0.26-1.20; log-rank P=0.059). Procedure-related major adverse events occurred significantly more often in MIPI than CA (20.8% versus 0%; P=0.029). CONCLUSIONS: Percutaneous pulmonary vein isolation was noninferior to MIPI in terms of efficacy and resulted in less complications. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov .

Right atrial preventive and antitachycardia pacing for prevention of paroxysmal atrial fibrillation in patients without bradycardia: a randomized study

Aims To investigate the efficacy of preventive and antitachycardia pacing (ATP) in patients with symptomatic paroxysmal atrial fibrillation (AF) without bradyarrhythmias. Methods and results In this randomized cross-over pilot study, we randomized 38 symptomatic paroxysmal AF patients 'without' bradyarrhythmias to atrial pacing lower rate 70 ppm and prevention and ATP therapies ON or to atrial pacing lower rate 34 ppm and prevention and ATP therapies OFF during 12 weeks with a 4 week washout period in between. The atrial lead was preferably placed in the inter-atrial septum. Antiarrhythmic drugs were continued during the study. Primary endpoint was AF burden. Mean age was 62 +/- 9 years and 27 (71%) patients had lone AF. Septal lead placement was accomplished in 26 (68%) patients. During the treatment ON, there was a trend for AF burden reduction [from median 3.3% (1.0-15.2) to 2.4% (0.2-12.2), P = 0.06, reduction 27%]. If septal lead placement was accomplished, AF burden reduction was statistically significant [44% reduction, from median 2.5% (1.0-8.0) to 1.4% (0.2-8.4), P = 0.03]. Quality of life and symptoms did not change, also not in the septal group. Conclusion A hybrid therapy of preventive and ATP pacing and antiarrhythmic drugs may significantly reduce but not abolish AF burden if septal pacing is realized
