Abstract
BACKGROUND
Increasing reports have demonstrated that recombinant human brain natriuretic peptide (rhBNP) can improve acute myocardial infarction (AMI) and heart failure. However, whether it can improve renal function and decrease the risk of contrast-induced nephropathy (CIN) in elderly AMI patients is still unclear.
AIM
To explore the effect of rhBNP on CIN in elderly AMI patients after percutaneous coronary intervention (PCI).
METHODS
One hundred and thirty-one elderly AMI patients underwent PCI from January 2017 to July 2021. Patients were either given 1 mL of 0.9% normal saline/(kg/h) for 72 h after PCI (control group, n = 66) and or intravenous rhBNP [1.5 mg/kg followed by 0.0075 mg/(kg/min)] for 72 h (rhBNP treatment group, n = 65). Serum creatinine and cystatin C levels, creatinine clearance rate, and eGFR were measured at 24 h, 48 h, and 72 h after PCI. Research nurses collected data on handwritten forms, and then stored them in password-protected electronic databases.
RESULTS
The creatinine clearance rate and eGFR were increased, while the creatinine and cystatin C levels were decreased significantly in the rhBNP treatment group compared to the control group at 48 h and 72 h. The incidence of CIN (P = 0.028) and acute heart failure (P = 0.017) also significantly decreased in the rhBNP group. No significant difference was noted between the two groups in cardiac death and recurrent AMI.
CONCLUSION
Early application of rhBNP could protect renal function and decrease the incidence of CIN after primary PCI and acute heart failure.
Core Tip: Increasing evidence indicates that emergency percutaneous coronary intervention (PCI) is the most effective method for the treatment of acute myocardial infarction (AMI). However, with the increase of emergency PCI, contrast-induced nephropathy (CIN) is becoming more and more common, which also leads to the increase of the proportion of patients with renal dysfunction, aggravating the cost of hospitalization and prolonging the length of hospital stay. CIN cannot be managed or prevented with current medications. Recombinant human B-type natriuretic peptide (rhBNP) is the natriuretic peptide receptor A, and increasing reports have demonstrated that rhBNP can improve AMI and heart failure. However, whether it can improve renal function and decrease the risk of CIN in elderly patients is still unclear. In this study, we explored the effectiveness of rhBNP treatment in postoperative CIN in elderly AMI patients. We found that early application of rhBNP after primary PCI could protect renal function, reduce serum creatinine and cystatin C levels, improve creatinine clearance rate, and decrease the risk of CIN and acute heart failure in AMI patients. We showed rhBNP as an effective drug to prevent CIN in the elderly after PCI.
