Purpose:

The purpose of this study is to determine, through continuous monitoring with a cardiac monitoring device placed under the skin, the incidence of atrial fibrillation or flutter (AF). The cardiac monitor will be placed in patients without symptoms but at risk for AF. It is hoped that this information may assist health care professionals in treatment decisions related to the early identification of patients at high risk for AF.


Study summary:

Background: Atrial fibrillation and atrial flutter (AF) are common cardiac arrhythmias that confer a substantial stroke burden largely because the vast majority of AF is asymptomatic and identified after a stroke has occurred. Until recently, only intermittent cardiac monitors were available, with most AF episodes remaining undetected due to poor sensitivity. Health care providers estimate the risk of stroke in AF patients using a patient's comorbidity profile to determine who should be treated with oral anticoagulant therapy for stroke prevention. The incidence of AF in patients with high stroke risk comorbidities is not known. The Medtronic Reveal insertable cardiac monitor (ICM) is a continuous monitoring device with excellent AF detection. Purpose and Study Objectives: The purpose of the PREDATE AF study is to determine the incidence of AF in asymptomatic patients at high risk for having AF in order to determine which patient characteristics are most predictive of the development of AF. The primary objective is to determine the AF incidence rate; secondary objectives include identifying the most important predictors of AF onset and identifying how physicians respond once AF has been discovered. Study Design: The trial is a prospective, single arm, open-label, single center clinical study which will enroll up to 360 patients at high risk of having AF based upon their comorbidity profile, who will then receive an ICM. Enrolled subjects will be followed for a minimum of 18 months to monitor for the detection of AF. Monthly ICM data transmissions will be the mechanism of AF detection, and this information will be utilized to determine the AF incidence rate


Criteria:

Inclusion Criteria: - Patient meets the approved FDA indication to receive the ICM - Patient is suspected, based on demographics, to be at high risk of having AF, as determined by the clinical investigator - Patient has a CHA2DS2-VASc score ≥ 2 [Note: stroke/TIA criterion as part of the CHA2DS2-VASc score for this trial is limited to either an ischemic stroke or TIA, which occurred more than one year prior to enrollment.] - Patient is 18 years of age or older - Patient has a life expectancy of 18 months or more Exclusion Criteria: - Patient has a documented history of AF or atrial flutter - Patient has a symptom complex consistent with an arrhythmia (where an ICM may have an alternate indication for use) - Patient had an ischemic stroke or TIA within past year prior to enrollment - Patient has a history of a hemorrhagic stroke - Patient is currently implanted with a permanent pacemaker, insertable loop recorder, implantable defibrillator, cardiac resynchronization therapy device (pacemaker or defibrillator) - NYHA Class IV Heart Failure patient - Patient had heart surgery within previous 90 days prior to enrollment - Patient had an MI within the previous 90 days prior to enrollment - Patient is taking chronic immunosuppressant therapy - Patient is taking an anti-arrhythmic drug - Patient is contraindicated for long term anticoagulation medication - Patient is taking a long-term anticoagulation medication - Any concomitant condition which, in the opinion of the investigator, would not allow safe participation in the study (e.g., drug addiction, alcohol abuse, emotional / psychological diagnosis) - Patient is enrolled in another study that could confound the results of this study, without documented pre-approval from the principal investigator - Patient has a creatinine clearance <30 ml/min or is on dialysis - Active pregnancy
