Predictive value of B-type natriuretic peptide (BNP) for adverse cardiac events in patients undergoing primary total knee arthroplasty (TKA)

DVPPB in comparison to preoperative and postoperative BNP can best predict cardiac events following primary TKA. Cigarette smoking, ASA III/IV/V, prior history of cardiac events, general anesthesia, surgery time, and tourniquet time are risk factors for DVPPB > 825.5 pg/ml. We hope these results could be helpful to optimize health care among patients undergoing primary TKA.
