1123-P: Stress Cardiac Biomarkers and Adverse Cardiac Outcomes in the CANagliflozin CardioVascular Assessment Study (CANVAS)

Abstract

SGLT2 inhibitors reduce risk of major adverse cardiovascular events (MACE) and hospitalization for heart failure (HHF) in patients with type 2 diabetes (T2D), but mechanisms remain unclear. We examined effects of canagliflozin vs. placebo on 3 prognostic biomarkers in CANVAS, as well as their predictive ability for outcomes of interest. High sensitivity cardiac troponin T (hs-cTnT; Roche Diagnostics), soluble (s)ST2 (Critical Diagnostics), and insulin-like growth factor binding protein 7 (IGFBP7; Roche Diagnostics) were measured in up to 3680 participants at baseline, 1 y, and for hs-cTnT and sST2, 6 y. Conventional statistical methods adjusting relevant covariates were used to relate biomarkers to risk for incident MACE or HHF. Higher concentration of all 3 biomarkers was associated with higher adjusted risk for incident MACE or HHF, with C-index improvements beyond covariates for MACE or HHF (Table). In terms of treatment effect, no biomarkers were differentially altered by 1 y but where data existed, both hs-cTnT (n=915; treatment coefficient [95% CI]: -0.064 [-0.121, -0.007]; p=0.027) and sST2 (n=828, treatment coefficient [95% CI]: -0.129 [-0.248, -0.010]; p=0.033) were reduced significantly at 6 y. Among patients with T2D, concentrations of hs-cTnT, sST2, and IGFBP7 were associated with risk for MACE and HHF. Canagliflozin slowed longer term (6 y) increases in hs-cTnT and sST2. Disclosure N.
