Biomarker assessment (including NT-proBNP, troponins, serum amyloid P component, and light-chain assays)
O
Outcome
Sensitivity, specificity, and prognostic significance of biomarkers for early detection and disease progressionsurrogate
NT-proBNP and troponins are highly sensitive and specific for the early diagnosis of cardiac amyloidosis, while novel biomarkers offer additional prognostic and subtyping value.
Limitations
- Significant variability existed in the correlation between biomarkers and imaging findings.
Cite This Study
Albulushi et al. (2024) conducted a meta-analysis in Cardiac amyloidosis (n=45). Biomarkers (NT-proBNP, troponins, serum amyloid P component, light-chain assays) was evaluated on Sensitivity, specificity, and prognostic significance of biomarkers. Across 45 studies, biomarkers such as NT-proBNP and troponins demonstrated high sensitivity and specificity for the early diagnosis of cardiac amyloidosis.
