Screening for Atrial Fibrillation in Pulmonary Embolism Study -SAFE-PE

Status Terminated

Clinical Trial Summary

Patients with newly diagnosed pulmonary embolism and high thromboembolic risk will be randomized to screening for atrial fibrillation or standard of care using intermittent ECG registration for at least two weeks.

Clinical Trial Description

Patients included in the study might be referred for an ultrasound of deep vein thrombosis unless this has already been performed. Blood will be drawn in a subset of patients to assess cardiac biomarkers, and stored in a biobank for further analysis of thrombotic biomarkers. If a computed tomography (CT) angiogram was used as diagnostic method for pulmonary embolism a radiologic review will be performed to assess presence of right atrium thrombus, with the reviewer will be blinded to the presence of atrial fibrillation (AF). In addition, an echocardiogram of the heart will be performed. Many patients with pulmonary embolism have prolonged symptoms of dyspnoea, and palpitations. These symptoms are also described in patients with atrial fibrillation. All participants will be asked to fill out a standardized quality of life (RAND-36)-, and a symptoms questionnaire (modified European Heart Rhythm association symptom scale). Upon inclusion all patients will be reviewed for factors predisposing to PE such as recent surgery, or illness requiring immobilisation within the past three months prior to index event. After inclusion patients will be randomised to screening for atrial fibrillation or standard of care. Participants who get randomised into the screening arm will be screened for AF using a validated, handheld ECG device at least twice daily for two weeks. Participants who get AF diagnosed during the study will be referred for appropriate cardiology follow-up and the anticoagulant therapy will be changed from a fixed time to continued (subject to yearly reviews). Patients will then be followed for five years using the Swedish death registry, and the Swedish national patient registry, in combination with the national prescription registry for the outcomes. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
