Risk of ischaemic stroke according to pattern of atrial fibrillation: analysis of 6563 aspirin-treated patients in ACTIVE-A and AVERROES

Aims The pattern of atrial fibrillation (AF) occurrence—paroxysmal, persistent, or permanent—is associated with progressive stages of atrial dysfunction and structural changes and may therefore be associated with progressively higher stroke risk. However, previous studies have not consistently shown AF pattern to predict stroke but have been hampered by methodological shortcomings of low power, variable event ascertainment, and variable anticoagulant use. Methods and results We analysed the rates of stroke and systemic embolism in 6563 aspirin-treated patients with AF from the ACTIVE-A/AVERROES databases. There was thorough searching for events and adjudication. Multivariable analyses were performed with the adjustment for known risk factors for stroke. Mean age of patients with paroxysmal, persistent, and permanent AF was 69.0 ± 9.9, 68.6 ± 10.2, and 71.9 ± 9.8 years (P

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.

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...

This study explored the proportion of NAFLD cases and increased liver fibrosis (LF), and the association between LF and either chronic kidney disease (CKD) or cardiovascular complications in T2DM patients. METHODS: - The study included 137 patients with non-insulin-treated T2DM and no known liver disease consecutively attending our diabetes outpatients service who underwent liver ultrasonography and liver stiffness measurement (LSM) using vibration-controlled transient elastography (FibroScan®). RESULTS: - The proportion of patients with hepatic steatosis on ultrasonography was 73.7%, and the proportion with ...

AbstractPurpose of reviewThis review will review the current knowledge and gaps in the literature on the relationship between surgery and ischemic stroke.FindingsSurgery and ischemic stroke are interrelated phenomena as surgery is an independent risk factor for stroke and perioperative stroke increases morbidity and mortality leading to poor outcomes after surgery. This relationship and the risk of adverse outcome apply not only the clinically apparent stroke in the perioperative period but also clinically silent brain infarction detected only on radiological studies. The risk of perioperative stroke depends on several fac...
