Background: Diabetic Cardiomyopathy (DbCM) is a form of Stage B heart failure (HF). Concentrations of N-terminal pro-B type natriuretic peptide (NT-proBNP) may predict risk for HF progression in persons with DbCM. The ARISE-HF study (NCT04083339) is evaluating efficacy of AT-001, a highly selective aldose reductase inhibitor (AT-001) to improve exercise tolerance in affected patients. The aim of this analysis was to assess association between baseline NT-proBNP and cardiac status in type 2 diabetes participants with DbCM.
Methods: Impaired exercise tolerance and baseline characteristics were evaluated in 679 patients with DbCM as a function of NT-proBNP at enrollment.
Results: Median NT-proBNP in the overall study population was 71 ng/L (IQR 35-133). Baseline characteristics were similar across NT-proBNP concentrations, however, participants with higher NT-proBNP had higher left atrial volume (p&lt;0.001) and higher right ventricular systolic pressure (p=0.04) on baseline echocardiogram. Higher NT-proBNP concentrations were associated with reduced physical activity reflected in lower PASE Score and a worse functional capacity reflected in lower peak VO2 (p&lt;0.001) (Table 1).
Conclusion: Among patients with DbCM, elevated NT-proBNP is associated with echocardiographic abnormalities and worse cardiac functional capacity and inversely associated with activity.
