Risk of cognitive decline in patients with covert stroke after non-cardiac surgery


  • Perioperative covert stroke (PCS) is associated with increased risk of cognitive decline and stroke/transient ischemic attack (TIA) 1 year after non-cardiac surgery (NCS).

Why this matters

  • Covert strokes (CS) are brain infarcts identified by magnetic resonance imaging (MRI) in the absence of clinical stroke symptoms, are more common than overt strokes in non-surgical settings, and are associated with higher risk of adverse outcomes.

  • Information on outcomes associated with PCS in the context of NCS are lacking but could help in development of prevention and management strategies.
