Atrial Fibrillation after Cardiac Surgery: Where are we now?
Author Information
Author(s): Dimpi Patel, Marc A Gillinov, Andreas Natale
Primary Institution: St David's Medical Center, Austin, Texas; Cleveland Clinic Foundation, Cleveland, Ohio
Hypothesis
What are the pathophysiology, risk factors, prophylaxis, and treatment options for postoperative atrial fibrillation (POAF)?
Conclusion
POAF occurs in 25-60% of patients depending on the type of cardiac surgery performed and is associated with increased morbidity and mortality.
Supporting Evidence
- POAF occurs in 25-60% of patients depending on the type of cardiac surgery performed.
- Prophylactic treatments reduce the likelihood of POAF.
- Patients with a higher baseline C-reactive protein level are more likely to develop POAF.
- β-receptor antagonists have been shown to reduce the incidence of POAF.
Takeaway
After heart surgery, many patients can get a heart flutter called atrial fibrillation, which can make them feel sick and stay in the hospital longer. Doctors are trying to find ways to prevent it.
Methodology
The authors reviewed literature from Medline and other references on postoperative atrial fibrillation from 1966 to 2008.
Potential Biases
Many studies were conducted at single centers, which may limit the generalizability of the findings.
Limitations
Inconsistencies in findings due to small sample sizes and non-standardized methods across studies.
Participant Demographics
The study discusses various demographics, including age and gender, but does not provide specific demographic data.
