#WeekendLecture
#ESUS
In most studies ~25% of ischemic stroke are classified as #cryptogenic
In 2014 the Embolic Stroke of Undetermined Source clinical construct was introduced, as a subset from cryptogenics
Criteria & diagnostic assessment were proposed

#WeekendLecture
#ESUS

Although a long list of causes was described, covert AF was conceived as perhaps the most important underlying mechanism
It was hypothesized that oral #anticoagulation may⏬ the risk of stroke recurence in #ESUS

#WeekendLecture
#ESUS

A systematic review in 2017 (from several authors of the pivotal paper) showed:
👉Frequency: 17% (9-25%) of IS
👉Mean age: 65
👉Recurrence: 4.5% per year
👉Younger, lower freq of vascular RFs and milder stroke vs non-ESUS IS

Benefits from #anticoagulation hypothesis was studied in 2 RCT

☝️Oral anticoagulation was not associated with lower rates of stroke recurrence compared with aspirin

#WeekendLecture
#ESUS

Researchers have been highlighting other possible #ESUS etiologies, relationship with AF, & subanalysis trying to identify pts who could benefit from specific therapies
ie:

Atrial Cardiopathy

#ESUS

Currently #ongoing RCTs are using more strict criteria, recruiting subgroups that may respond better to anticoagulation

#WeekendLecture
#ESUS

Recently, a group of experts made a "reexamination" of #ESUS construct, and proposed to #refine its definition, based on current evidence, ie, from #longterm monitoring, imaging, #atrial cardiopathy.
