Natriuretic peptides and risk of type 2 diabetes: Results from the Biomarkers for Cardiovascular Risk Assessment in Europe (BiomarCaRE) Consortium
Objective: Natriuretic peptide (NP) concentrations are increased in cardiovascular diseases (CVD) but are associated with a lower diabetes risk. We investigated associations of N-terminal pro-B-type NP (NT-proBNP) and mid-regional pro-atrial NP (MR-proANP) with incident type 2 diabetes stratified by the presence of CVD.
Research Design and Methods: Based on the Biomarkers for Cardiovascular Risk Assessment in Europe-(BiomarCaRE) Consortium, we included 45,477 participants with NT-proBNP measurements (1,707 developed type 2 diabetes over 6.5 years of median follow-up; among these, 209 had CVD at baseline) and 11,537 participants with MR-proANP measurements (857 developed type 2 diabetes over 13.8 years of median follow-up; among these, 106 had CVD at baseline). The associations were estimated using multivariable Cox regression models.
Results: Both NPs were inversely associated with incident type 2 diabetes (hazard ratios [95%CI] per 1-standard deviation increase of log NP: 0.84 [0.79; 0.89] for NT-proBNP and 0.77 [0.71; 0.83] for MR-proANP). The inverse association between NT-proBNP and type 2 diabetes was significant in individuals without, but not in individuals with CVD (0.81 [0.76; 0.86] vs 1.04 [0.90; 1.19]; P-multiplicative interaction= 0.001). There was no significant difference in the association of MR-proANP with type 2 diabetes between individuals without and with CVD (0.75 [0.69; 0.82] vs 0.81 [0.66; 0.99]; P-multiplicative interaction= 0.236).
Conclusions: NT-proBNP and MR-proANP are inversely associated with incident type 2 diabetes. However, the inverse association of NT-proBNP seems to be modified by the presence of CVD. Further investigations are warranted to confirm our findings and to investigate the underlying mechanisms.
