Continuous ECG monitoring enhances detection of AF after cardiac surgery: JAMA
In post-cardiac surgical patients, continuous cardiac rhythm monitoring enhances detection of Postoperative atrial fibrillation (POAF), suggests a study published in the JAMA Netw. Open.
Postoperative atrial fibrillation (POAF) occurring after cardiac surgery is associated with adverse outcomes. Whether POAF persists beyond discharge is not well defined.
A group of researches from Canada conducted a study to determine whether continuous cardiac rhythm monitoring enhances detection of POAF among cardiac surgical patients during the first 30 days after hospital discharge compared with usual care.
This study is an investigator-initiated, open-label, multicenter, randomized clinical trial conducted at 10 Canadian centres. Enrollment spanned from March 2017 to March 2020, with follow-up through September 11, 2020. As a result of the COVID-19 pandemic, enrollment stopped on July 17, 2020, at which point 85% of the proposed sample size was enrolled. Cardiac surgical patients with CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes, prior stroke or transient ischemic attack, vascular disease, age 65-74 years, female sex) score greater than or equal to 4 or greater than or equal to 2 with risk factors for POAF, no history of preoperative AF, and POAF lasting less than 24 hours during hospitalization were enrolled.
