Detection of Occult Paroxysmal Atrial Fibrillation After Stroke Using Prolonged Ambulatory Cardiac Monitoring

NCT01325545 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 132

Last updated 2011-12-23

No results posted yet for this study

Summary

About one-third of patients with stroke have no documented cause for the cerebrovascular event (known as cryptogenic strokes). Atrial fibrillation is a common cause of stroke, but when transient (paroxysmal) it may remain undiagnosed. Recent data suggest that occult paroxysmal atrial fibrillation may be identified in patients with cryptogenic strokes using prolonged ambulatory cardiac rhythm monitors.

The investigators designed this study pursuing the following goals:

1. To determine the prevalence of occult paroxysmal atrial fibrillation in patients with cryptogenic stroke using long-term mobile cardiac outpatient telemetry.
2. To compare this prevalence to that found in a control group with stroke of known, non-cardioembolic cause.
3. To look for clinical, laboratory, echocardiographic, and imaging data that serve as risk factors for occult paroxysmal atrial fibrillation in patients with cryptogenic stroke.
4. To examine the utility of mobile cardiac outpatient telemetry, a relatively new diagnostic tool, in the evaluation of patients with cryptogenic stroke.
