Utility of left atrial strain for predicting atrial fibrillation following ischemic stroke

AbstractTwenty-five percent of ischemic strokes (IS) are cryptogenic, but it is estimated that paroxysmal atrial fibrillation (PAF) is the underlying cause in up to a third of cases. We aimed to investigate the predictive value of speckle tracking of the left atrium (LA) in diagnosing PAF in IS patients. We retrospectively studied 186 IS patients with a clinical echocardiographic examination during sinus rhythm. Outcome was PAF defined by at least one reported episode of AF following their IS. Conventional echocardiographic measures were performed. Global longitudinal strain (GLS), LA reservoir-( εs), conduit-( εe), contraction-strain ( εa) and LA dyssynchrony (standard deviation of time-to-peak εs; LA SD-T2P) were obtained by left ventricular and LA speckle tracking. Of 186 patients, 28 (15%) were diagnosed with PAF. PAF-patients did not differ from non-PAF patients with regards to GLS nor SD-TPS, but atrial strain measures were significantly impaired at baseline ( εs 27 vs. 35%, εe 12 vs. 16%, εa 15 vs. 18%, p

Prompt detection of atrial fibrillation (AF) is essential for optimal secondary stroke prevention, but routine long-term cardiac monitoring of all ischemic stroke patients is neither practical nor affordable. We aimed to develop and validate a risk score to identify patients at risk for newly diagnosed AF (NDAF) after ischemic stroke.

We examined frequency, clinical characteristics and AF‐related management and outcomes amongst this patient population.MethodsWe retrospectively studied consecutive probands with inherited cardiomyopathy (n=962) and inherited arrhythmia syndromes (n=195) evaluated between 2002 ‐2018.ResultsAF was observed in 5 ‐31% of patients, with the highest frequency in HCM. Age of AF onset was 45.8 ± 21.9 years in the inherited arrhythmia syndromes compared to 53.3 ± 15.3 years in the inherited cardiomyopathies, with 4 CPVT patients developing AF at median age of 20 years. Overall, 11% of patients with AF had a t r...

Abstract PURPOSE: In China, dabigatran and rivaroxaban are the only approved non-vitamin K antagonist oral anticoagulants for the treatment of atrial fibrillation (AF). The goal of this article was to assess the cost-effectiveness of dabigatran versus rivaroxaban for the prevention of stroke and systemic embolism in Chinese patients with AF from the perspective of the Chinese health care system. METHODS: A Markov model was constructed to estimate the cost-effectiveness of dabigatran versus rivaroxaban. Clinical events were modeled for a lifetime horizon, based on clinical efficacy data from indirect treatment...

Low-dose aspirin reduces the frequency of adverse vascular events in those at increased risk of occlusive cardiovascular disease (CVD). People who benefit include those: with a history of myocardial infarction, ischaemic stroke, unstable or stable angina, peripheral arterial disease, or atrial fibrillation (1). The pathophysiology of CVD risk contributes to cognitive decline through multiple pathways that include cerebral hypo-perfusion, hypoxia, hippocampal atrophy, emboli, or infarcts (2,3). However, the value of aspirin use in prevention of cognitive impairment remains uncertain since results relating to the influence o...

Background: The efficacy of patent foramen ovale (PFO) closure remains controversial, and it is unclear which patient groups are best benefited. We performed this meta-analysis to clarify the efficacy of PFO closure of younger patients for prevention of recurrent ischemic neurological events. Methods: We systematically searched for studies of PFO closure for younger patients under the age of 55, and pooled available data on PFO closure of younger vs older patients and on PFO closure of younger patients vs medical therapy. The primary endpoints were the composite outcome of recurrent ischemic neurological events [strok...
