Background
Blood natriuretic peptide (NP) levels have been reported to be useful for predicting postoperative atrial fibrillation (AF). We aimed to quantitatively synthesize the current evidence of the accuracy of using NP levels in predicting postoperative AF.
Methods and Results
Medline, Embase, and reference lists were searched. Studies were included if either brain natriuretic peptide (BNP) or N-terminal pro-b type natriuretic peptide (NT-proBNP) had been evaluated perioperatively to predict postoperative AF. Data were analyzed to obtain summary accuracy estimates. Data from 1,844 patients in 10 studies were analyzed. Summary estimates for the sensitivity and specificity of using NP levels for predicting postoperative AF were 75 % [95 % confidence interval (CI) 67–79 %] and 80 % (95 % CI 62–91 %), respectively. The overall diagnostic odds ratio was 3.28 (95 % CI 2.23–4.84). Subgroup analysis showed that elevated NP levels in the perioperative period were a strong independent predictor of postoperative AF. NT-proBNP appeared to have better predictive value than BNP, as did postoperative assessment over preoperative assessment. BNP had a better correlation with postoperative AF in patients undergoing thoracic surgery than in patients undergoing cardiac surgery.
Conclusions
Perioperative assessment of the natriuretic peptide level in patients undergoing major cardiothoracic surgery could be a valuable diagnostic aid for identifying patients at high risk of developing postoperative AF, and for providing critical clinical information to guide prophylactic antiarrhythmic therapy in the perioperative period.
