AF DETECTION AND TREATMENT MATTERS

Page 9: This is the new PowerPoint template...PRESENTATION. AGENDA Epidemiology ... WickramasingheK, et al. European Cardiovascular Disease Statistics 2017 edition. Eur Heart Network 2017:192

Despite an excessive diagnostic workup, about 30% of the stroke patients are still cryptogenic1-6

Most cryptogenic stroke patients receive anti-platelet for secondary prevention7

Long-term monitoring reveals AF in ~30% of cryptogenic stroke patients8

This enables treatment changefrom antiplatelet to oralanticoagulation

CLINICAL IMPACT: MORE APPROPRIATE CARE

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

Extensive external monitoring only 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

REAL WORLD VALIDATION OF CRYSTAL AF RESULTSRogers, AAN, 2016

1247 real-world cryptogenic stroke patients monitored by Reveal LINQ™

Cryptogenic stroke diagnosis: physician’s discretion

Follow-up: 12 months

Diagnostic yield at 12 months: 16.3%(n=147)

Median time to detection: 86 days

Analysis supports results of CRYSTAL AF

Continuous monitoring for periods longer 30 days may be warranted in CS patients

Rogers J et al, American Academy of Neurology, http://www.abstractsonline.com/pp8/#!/4046/presentation/8072 2016

72% of AF patients would bemissed if monitoring stoppedat 30 days

1247 cryptogenic stroke patients in the DiscoveryLink database

Follow-up: up to 2 years (579 ± 222 days)

AF ≥2 min was detected in 16.3% at 1 year and in 21.5% at 2 years (vs. 4.6% at 30 days)

Median time to AF detection: 112 days (IQR 35-293)

In 74% of patients, the longest episode was >1h

In most patents with multiple AF episodes, durations increased following initial episode

79% of AF patients would have been missed with 30 days of monitoring

CONCLUSIONS

Approximately one-third of ischemic strokes are classified as cryptogenic

Up to 30% of cryptogenic stroke patients have undiagnosed AF

The more you look, the more you find Short- to intermediate-term cardiac rhythm monitoring may not be enough

to detect paroxysmal AF in your cryptogenic stroke patients

CRYSTAL-AF demonstrates superiority of continuous, long-term monitoring of cryptogenic stroke patients with an ICM

2016 ESC guidelines recommend monitoring with ICMs in cryptogenic stroke patients

Reveal LINQ™ ICM Up to 3 years of continuous cardiac monitoring with the world’s smallest ICM

Proven AF detection algorithm with industry leading accuracy

Safe for use in MRI setting same day at 1.5 and 3.0 Tesla*

*Reveal LINQ™ ICM has been demonstrated to pose no known hazards in a specified MRI environment with specified conditions of use. Please see the Reveal LINQ™ ICM clinician manual or MRI technical manual for more details.

PATIENT CASE STUDY

Reveal LINQ™ ICM used to discover AF in 22-year-old stroke patientOn his way to a soccer game, 22-year-old Scott suddenly began wobbling. His head started throbbing. What he thought was dehydration turned out to be much worse. The college student had suffered a stroke. Surgeons removed a blood clot in his brain, but a looming question remained: What caused the stroke in this seemingly healthy young man?

Scott’s doctors suspected it was the result of atrial fibrillation (AF). So Scott’s doctors turned to the Reveal LINQ™ ICM, which, within a few months, confirmed he had AF.

The diagnosis not only gave Scott’s doctors the information they needed to prescribe stroke-preventive blood thinners; it gave Scott the peace of mind to live life fully again.

MRA of head and neck and chest x-rayreturned normal results

TTE showed normal LV size and function

Subsequent TEE confirmed these results,also showed that her atrial size was at theupper limits of normal

TEE showed that there was no thrombus and normal velocities in the LAA,a normal aortic arch, and no evidence of a patent foramen ovale

24-hour telemetry monitoring was negative for arrhythmia

CASE STUDY

The patient underwent extensive additional evaluation, including a work-up for hypercoagulability, which was negative

She was subsequently implanted with an ICM and discharged on clopidogrel and aspirin

After 2 months of monitoring, episodes of paroxysmal AF lasting 15 to 90 minutes were detected

Episodes were asymptomatic despite mean ventricular rates > 120 BPM

The patient was subsequently prescribed an oral anticoagulant
