Inform your secondary stroke prevention strategies.

One in four stroke survivors will experience another stroke within five years.1 Are you doing everything you can to find risk factors that could lead to another ischemic stroke in your patients?

  • Atrial fibrillation (AF) was found in 30% of patients with cryptogenic stroke up to three years post-stroke.2
  • AF was found in 12.1% of large- and small-vessel stroke patients at 12 months post-stroke.3
  • 45.5% of first recurrent strokes have a different subtype than the index stroke.4

AF is a major risk factor for stroke. AF detection matters.

Find AF. Treat AF. Prevent stroke.

The use of prolonged cardiac monitoring (PCM) has a potential impact on secondary stroke prevention, as patients with cryptogenic stroke/TIA undergoing PCM compared to conventional cardiac monitoring show5:

  • 2.5 times increased incidence of AF detection.
  • 2.1 times increased incidence of anticoagulant initiation.
  • 55% decreased risk of recurrent stroke.

LINQ™ family of ICMs. Accuracy matters.

Patients with a LINQ insertable cardiac monitor (ICM) experienced fewer secondary strokes two years following a cryptogenic stroke.6

The LINQ family of ICMs (Reveal LINQ™ ICM and LINQ II™ ICM) detect asymptomatic AF while tracking daily AF burden and ventricular rates in stroke patients7 and may enable subsequent medical decisions and long-term management of AF.2,8 They also allow for higher diagnostic yield and better patient compliance compared to external monitoring in stroke patients.2,7,8
