“Development of AF after CABG linked to higher risk of cerebrovascular accidents at 10 years”- the study report published by Cardiac Rhythm News tackles a study conducted Dr. Benedetto et al on Coronary Artery Bypass Graft (CABG) patients and the risk of developing post-operative AF.
The 10 year study included 3023 patients, who have undergone CABG surgery, reveals that 734 patients developed postoperative atrial fibrillation (AF).
A study published in circulation has found that Patients with postoperative atrial fibrillation (PAF) after undergoing a CABG are at a higher risk of cerebrovascular accidents (CVAs) up to 10 years after the procedure.
Benedetto and colleagues have sighted that the incidence of PAF after a CABG ranges between 20-40% of patients. Another noteworthy factor identified is that postoperative AF develops within the first week after the surgery, at a median time of 2 days post surgery.
Postoperative AF has traditionally been considered a transient and benign complication of the CABG procedure. However, recent studies have reported an association between PAF and increase in early mortality and morbidity rates that includes; stroke, renal, respiratory failure, and a prolonged intensive care unit duration. Benedetto and colleagues also stated that – although postoperative AF may not be directly responsible for these poor outcomes, it is likely to contribute to increased morbidity and mortality after cardiac surgery.
In conclusion, 20-40% of patients who have undergone a coronary artery bypass graft (CABG) surgery are at risk of developing postoperative atrial fibrillation. If they are not provided with the appropriate medical follow-up and screening after surgery, these cases can lead to a stroke, renal and respiratory failure.
