A Unified High-Sensitivity Cardiac Troponin I Threshold of 80 ng/L for Risk Stratification in Wild-Type Transthyretin Amyloid Cardiomyopathy
This multicenter study identifies high-sensitivity cardiac troponin I (hs-cTnI) as a potent, independent predictor of mortality in wild-type transthyretin amyloid cardiomyopathy. A universal threshold of 80 ng/L, integrated with natriuretic peptides, provides a robust staging system across multiple assay platforms.
