Rationale Patients with transient ischemic attack or minor stroke are at high risk of early recurrent cerebrovascular events. Anticoagulation with heparin or warfarin acutely after ischemic stroke is at least as efficacious as aspirin for preventing recurrent events but is associated with an increased risk of clinical worsening due to hemorrhagic transformation. Aim and hypothesis We aim to demonstrate the safety of early anticoagulation with dabigatran, an oral direct thrombin inhibitor, in acute cerebrovascular syndrome patients.

Until recently, there has been no specific reversal agent for DOACs. Now, a specific antidote for the direct thrombin inhibitor, dabigatran has been approved for use, and antidotes for factor Xa inhibitors (rivaroxaban, apixaban and edoxaban) are being developed.

We report the effects of apixaban versus acetylsalicylic acid (ASA) in older patients (≥75 years and ≥85 years) compared with younger patients with AF unsuitable for vitamin K antagonists.
Methods: AVERROES (Apixaban Versus ASA to Prevent Stroke In AF Patients Who Have Failed or Are Unsuitable for Vitamin K Antagonist Treatment) trial (n = 5,599) included 1,898 patients ≥75 years and 366 patients ≥85 years.
Background: Randomized clinical trials provide the most reliable evidence to guide the management of stroke and threatened stroke and reflect the interests of the stroke research community. The spectrum of phase III randomized clinical trials in stroke has not been previously characterized.
Methods: Phase III stroke randomized clinical trials published between 2012 and 2014 were identified by search of the Cochrane Central Register of Controlled Trials supplemented by recent publications known to the co-authors.
Asymptomatic carotid stenosis (ACS) exceeding 50% is present in about 2% of 60-year-old patients and an even higher fraction of older individuals. The major independent risk factors include advancing age, male sex, tobacco smoking, and a history of vascular disease. The best available evidence does not support either population screening for ACS or routine carotid revascularization when ACS is discovered.
View Article and Find Full Text PDFAtrial fibrillation (AF) is an important cause of preventable, disabling stroke and is increasingly prevalent with advancing age. As life expectancies increase around the world, AF-related stroke is a growing global public health concern. Most AF patients are elderly (≥75 years old) and increasing age is a consistent independent risk factor for AF-associated stroke.
