Elevated pre- & postoperative BNP tied to complications in hypertensive & diabetic patients undergoing surgery
22 Mar, 2023 | 13:28h | UTCSummary: This study aimed to assess if preoperative and postoperative serum B-type natriuretic peptide levels (BNP) could predict postoperative complications in hypertensive and diabetic patients after non-cardiac surgery. The study involved 260 adult participants and measured BNP levels before and after surgery. The primary outcome was the change in BNP levels and the development of postoperative complications within 30 days of surgery.
Results showed that patients who developed postoperative complications had significantly higher serum BNP levels both before and after surgery. The preoperative BNP levels (baseline BNP) in patients with complications were 152.02 pg/mL ± 106.56 compared to 44.90 pg/mL ± 44.22 in patients without complications. Similarly, postoperative BNP levels in patients with complications were 313.99 pg/mL ± 121.29, while in patients without complications, they were 83.95 pg/mL ± 70.19.
Although the study does not provide specific cutoff values, higher BNP levels both preoperatively and postoperatively are associated with an increased risk of complications in hypertensive and diabetic patients undergoing non-cardiac surgery. Further multicenter prospective studies with a larger population are needed to confirm the role of BNP in predicting surgical prognosis.
