NPPB and cardiac hypertrophy: There existed a significantly positive correlation between circulating hs-cTnT and LAD, LVEDD, LVEDS, IVST, PWT and NT-pro-BNP (rho = 0.2705, 0.1300, 0.1378, 0.2256, 0.1742 and 0.1049; all p < 0.05) in spearman correlation analysis, potentially indicating a significant relationship between cardiac hypertrophy and circulating hs-cTnT.
