Implication

May aid postoperative AF risk stratification after CABG but should not yet change practice; leaves open need for prospective interventional trials.

Structured PICO

Does elevated preoperative BNP predict postoperative atrial fibrillation in patients undergoing isolated CABG?

Population

144 consecutive patients (51 women, 93 men) scheduled for elective first-time isolated CABG with cardiopulmonary bypass. Mean age 58.9 ± 9.8 years. Exclusions: urgent operation, off-pump surgery, renal insufficiency (creatinine >1.5 mg/dL), acute MI <1 month before surgery, mitral valve insufficiency (>+1), and history of AF.

Intervention

Preoperative brain natriuretic peptide (BNP) level measurement

Outcome

Postoperative new-onset atrial fibrillation (AF) lasting longer than 10 minuteshard clinical

Elevated preoperative BNP levels and advanced age are significant independent predictors of new-onset postoperative atrial fibrillation in patients undergoing isolated CABG.

Limitations

Small size of the study group
Absence of continuous Holter monitoring after the first 72 hours, which may have missed short and asymptomatic episodes of AF
