CRYSTAL-AF STUDY

Continuous monitoring with Reveal™ Insertable Cardiac Monitoring (ICM) is superior to standard medical care for AF detection in patients with a cryptogenic stroke1

As published in the New England Journal of Medicine

 KEY FINDINGS

CRYSTAL AF 7.3-30-97
 

CLINICAL IMPACT: MORE APPROPRIATE CARE

Short-term cardiac monitoring is NOT sufficient for AF detection in cryptogenic stroke

  • Extensive external monitoring found few patients with AF
    • In the control group at 6 months, only 3 patients were found to have AF; yet there were 88 conventional ECGs, 20 24-hour Holters, and 1 event recorder used
  • Reveal ICM detected over 7 times more patients with AF at the 12-month end point
