[Research progress of postoperative atrial fibrillation]

Area of Science:

• Cardiology
• Cardiac Surgery
• Critical Care Medicine

Context:

• Postoperative atrial fibrillation (POAF) is the most frequent complication following cardiac surgery.
• POAF can lead to hemodynamic instability, extended hospital stays, and increased patient mortality.
• Understanding POAF's mechanisms is vital for effective clinical management.

Purpose:

• To summarize the current understanding of postoperative atrial fibrillation (POAF) mechanisms.
• To outline the predictive factors and therapeutic strategies for POAF.
• To highlight the clinical significance of POAF in cardiac surgery patients.

Summary:

• POAF is multifactorial, involving cardiomyocyte injury, sympathetic nervous system activation, and inflammatory responses.
• Prediction models utilize pre-, intra-, and postoperative data to identify patients at risk for POAF.
• Management strategies include heart rate and rhythm control, alongside antithrombotic therapy.

Impact:

• Improved prediction and timely management of POAF can mitigate its adverse effects.
• Reducing POAF incidence and duration can enhance patient recovery and reduce healthcare costs.
• Further research into POAF mechanisms may reveal novel therapeutic targets.
