Canada129 participantsStarted 2014-01

Plain-language summary

The ASSERT-III study aims to determine the incidence of sub-clinical (silent) atrial fibrillation (AF) among elderly patients with hypertension and at least one other risk factor for AF. This will be accomplished by monitoring with a wireless external loop monitor for 30 to 60 days.

Inclusion criteria

✓. Age ≥ 80 years
✓. History of hypertension OR a blood pressure of ≥ 140/90 mmHg
✓. Attending a primary care clinic, OR ambulatory resident of a chronic care facility
✓. At least one of the following additional risk factors for developing AF:
✓. Diabetes
✓. Body mass index ≥ 30
✓. History of smoking
✓. Documented Obstructive sleep apnea

Exclusion criteria

✕. ECG documented history of AF or atrial flutter, with an episode duration ≥ 6 minutes
✕. Existing implanted pacemaker or defibrillator
✕. Patients considered by the investigator to be unsuitable for study follow-up because the patient:
✕. is unreliable concerning the requirements for follow-up during the study and/or compliance with the use of the external loop recorder
✕. has a life expectancy less that the expected study duration due to concomitant disease
✕. has a condition which in the opinion of the investigator, would not allow current chronic treatment with anticoagultion -

What they're measuring
