AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults who just had surgery that was not on the heart and who have a higher risk of an irregular heartbeat (atrial fibrillation) afterwards. They wear a heart monitor for up to 14 days.
- Age
- Adults aged 18 to 120 years. The higher-risk groups are 55-64, 65-74 and 75 or older.
- Sex
- All sexes can join.
- Disease stage
- Surgery that was not on the heart within the past 72 hours, with an overnight hospital stay or a day surgery that is a big strain on the body. Higher risk of heart rhythm problems, such as known heart or vascular disease, a CHA2DS2-VASc score of 3 or more (2 or more at age 65-74), or high troponin after surgery. Everyone aged 75 or older is in this group.
- Earlier treatment
- No need for long-term blood thinners or long-term dual antiplatelet treatment. No heart surgery in the past 35 days.
- Biomarker or test result
- Troponin level after surgery: an elevated level counts as a risk factor for people aged 55-74.
Main reasons for not taking part
- Known long-lasting atrial fibrillation before the surgery
- Need for long-term blood thinners (anticoagulation)
- Severe kidney problems or severe liver cirrhosis
- Stroke in the past 14 days
- Pregnant or breastfeeding, or able to have children and not using effective birth control

Enhanced DETECTion of PeriOperative Atrial Fibrillation After Noncardiac Surgery with Continuous Electrocardiographic Monitoring
This is a multicentre prospective cohort study where patients will receive up to 14 days of continuous ECG monitoring by wearing a portable monitoring device, starting within 72 hours after noncardiac surgery.
Inclusion: Had undergone noncardiac surgery within the past 72 hours and requiring, or expected to require, at least one of the following:; an overnight hospital admission after surgery; day surgery that would result in a large enough physiological insult to be able to cause POAF. Procedures excluded include those that are conducted using local anesthesia alone, are less than 30 minutes in duration, and/or are judged to be of low physiologic insult by the local investigator; Have one of the following high-risk criteria; age 55-64 years, and having either established cardiovascular disease, recent major vascular surgery, a CHA2DS2-VASc score ≥3, or an elevated postoperative troponin level; age 65-74 years, and having either established cardiovascular disease, recent major vascular surgery, a CHA2DS2-VASc score ≥2, or an elevated postoperative troponin level; or; age ≥75 years; Provide written informed consent to participate.
Exclusion: Known life expectancy <1 year due to concomitant disease; Previously enrolled in DETECT-POAF; History of documented chronic (i.e., non-transient) AF before noncardiac surgery; Severe renal insufficiency; Acute stroke in the past 14 days; Underwent cardiac surgery in the past 35 days; History of nontraumatic intracranial, intraocular, or spinal bleeding; Hemorrhagic disorder or bleeding diathesis; Known contact allergy to monitoring device and/or its peripheral components; Need for long-term systemic anticoagulation; Ongoing need for long-term dual antiplatelet treatment; Contraindication to oral anticoagulation; Severe liver cirrhosis; Women who are pregnant, breastfeeding, or of childbearing potential not taking effective contraception; Expected to be non-compliant with follow-up and/or device use.
