Reduced Doses of Direct Oral Anticoagulants in Ischemic Stroke Patients with Nonvalvular Atrial Fibrillation

Background: The choice of standard or reduced doses of direct oral anticoagulants (DOACs) depends on patients ’ age, body weight, and renal function based on package instructions. Our aim was to conduct a simulation of DOAC dose using patients’ data obtained on admission. Methods: This retrospective study included 314 ischemic stroke patients with nonvalvular atrial fibrillation admitted to our hospital between September 2014 and February 2018. Data on age, body weight, creatinine, and creatinine clearance were collected for each subject, and simulation was conducted for the dose of each DOAC.

ConclusionsIn AF patients who survived an ICH, restarting OAC was not associated with a greater risk of recurrent ICH. Evidence from randomized controlled studies is needed to further clarify the clinical benefit of restarting OAC in this high-risk population. Further evaluation of which individuals benefit from restarting OAC is also needed to provide more clinical guidance.

CONCLUSIONS: Compared to warfarin, NOACs were associated with a significantly lower risk of adverse events, with heterogeneity in treatment effects among different age strata. Overall, the clear safety signal in favor of NOACs over warfarin was evident irrespective of age strata, being most marked in the most elderly. PMID: 31809694 [PubMed - as supplied by publisher]

AbstractThe best strategy in atrial fibrillation (AF) after  >  12 months after an acute coronary syndrome or in patients with chronic coronary syndrome without an indication for interventional revascularization remains unclear. European guidelines generally recommend therapy with oral anticoagulation (OAC) alone, whereas North American guidelines advise com bination therapy consisting of OAC plus antiplatelet therapy in some patients. We performed a meta-analysis of available trials comparing these treatment strategies. The primary endpoint was major adverse cardiac events (MACE), secondary endp...

AbstractPurpose of reviewCryptogenic stroke describes a subset of ischemic stroke for which no cause can be found despite a structured investigation. There are a number of putative mechanisms of cryptogenic ischemic stroke including a covert structural cardiac lesion, paroxysmal atrial fibrillation, hypercoagulable state or undiagnosed malignancy. Because many of these proposed mechanisms are embolic – and based on studies of thrombus history showing commonalities between thrombus composition between cardioembolic and cryptogenic strokes – the concept of embolic stroke of undetermined source (ESUS) (Hart et al....

AbstractSeveral studies have explored the use of NOACs compared with vitamin K antagonists (VKAs) in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF); and therefore, we aimed to compare the efficacy and safety outcomes of NOACs with VKAs in this population. We systematically searched the PubMed and Embase databases until August 5, 2019 for studies that compared the effect of NOACs with VKAs in patients with HCM and AF. The risk ratios (RRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. A total of four observational studies were included in this meta-analysis. Over...

This study identified 17,371 HCM patients without AF and utilized propensity-score-matching to identify one-to-one matched control of general population with AF receiving oral anti-coagulants (OACs). During a median follow-up of 7.3 years, 847 (4.9%) subjects experienced IS with the incidence of 0.589/100 person-years. The corresponding matched controls experienced 788 (4.5%) events with the incidence of 0.494/100 person-years. Compared with control, HCM patients had similar risk of IS (Hazard ratios [HRs] 0.965, 95% confidence interval [CI] 0.854-1.091). HCM patients with age above 65 years had a significantly increased r...

CONCLUSION:  In AF patients with malignancy, NOACs appear at least as effective as VKAs in preventing thrombotic events and reduce intracranial bleeding. NOACs may represent a valid and more practical alternative to VKAs in this setting of high-risk patients. PMID: 31785599 [PubMed - as supplied by publisher]

AbstractPurpose of ReviewThis review aims to explore the relationship between AF and carotid atherosclerosis, and the impact on the outcomes of cardiovascular and cerebrovascular events. Also, our aim is to critically review current knowledge and delineate future directions for effective treatment or prevention as well as strategies for improvement of the quality of life and survival.Recent FindingsAtrial fibrillation (AF) is the most common arrhythmia, increasing the risk of stroke and cardiovascular morbidity and mortality representing a significant worldwide public health problem. On the other hand, carotid artery ather...
