Standardized regression coefficients between blood variable levels and echocardiographic measurements. β, Standardized regression coefficient. Regression line drawn for β > 0.3. When the hs-TnI level was below the limit of detection (0.1 pg/mL), we assumed that hs-TnI was present at 0.1 pg/mL serum level. BSA, body surface area; BNP, brain natriuretic peptide; hs-TnI, high-sensitivity troponin I; NT-proBNP, N-terminal precursor protein BNP; E, early diastolic mitral flow velocity; e’, average of early diastolic septal and lateral mitral annular velocities; LA, left atrium; s’, average of systolic septal and lateral mitral annular velocities
