Prognostic implication of DPD quantification in transthyretin cardiac amyloidosis.
Aims: Quantification of cardiac [99mTc]-3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) uptake enhances diagnostic capabilities and may facilitate prognostic stratification in patients with transthyretin cardiac amyloidosis (ATTR-CA). This study aimed to evaluate the association of quantitative left ventricular (LV) DPD uptake with myocardial structure and function, and their implications on outcome in ATTR-CA.
Methods and results: Consecutive ATTR-CA patients (n=100) undergoing planar DPD scintigraphy with Perugini grade 2 or 3, alongside quantitative DPD SPECT/CT imaging and speckle-tracking echocardiography between 2019 and 2023, were included and divided into two cohorts based on median DPD retention index (low DPD uptake: ≤5.4, n=50; high DPD uptake: >5.4, n=50). The DPD retention index showed significant, albeit weak to modest, correlations with LV global longitudinal strain (LV-GLS: r=0.366,p<0.001), right ventricular free wall longitudinal strain (RV-FW-LS: r=0.316,p=0.002), LV diastolic function (E/e' average: r=0.304, p=0.013), NT-proBNP (r=0.332,p<0.001), troponin T (r=0.233,p=0.022), 6-minute walk distance (6MWD: r=-0.222,p=0.033) and National Amyloidosis Centre (NAC) stage (r=0.294,p=0.003). ATTR-CA patients in the high DPD uptake cohort demonstrated more advanced disease severity regarding longitudinal cardiac function (LV-GLS: p=0.012, RV-FW-LS: p=0.036), LV diastolic function (E/e' average: p=0.035), cardiac biomarkers (NT-proBNP: p=0.012, troponin T: p=0.044), exercise capacity (6MWD: p=0.035) and disease stage (NAC stage I: p=0.045, III: p=0.006), and experienced adverse outcomes compared to the low DPD uptake cohort [composite endpoint: all-cause death or heart failure hospitalization, HR: 2.873 (95%CI:1.439-5.737), p=0.003; DPD retention index: adjusted HR 1.221 (95%CI: 1.078-1.383), p=0.002].
Conclusion: In ATTR-CA, enhanced quantitative LV DPD uptake indicates advanced disease severity and is associated with adverse outcome. DPD quantification may facilitate prognostic stratification when diagnosing patients with ATTR-CA.
期刊介绍：
European Heart Journal – Cardiovascular Imaging is a monthly international peer reviewed journal dealing with Cardiovascular Imaging. It is an official publication of the European Association of Cardiovascular Imaging, a branch of the European Society of Cardiology.
The journal aims to publish the highest quality material, both scientific and clinical from all areas of cardiovascular imaging including echocardiography, magnetic resonance, computed tomography, nuclear and invasive imaging. A range of article types will be considered, including original research, reviews, editorials, image focus, letters and recommendation papers from relevant groups of the European Society of Cardiology. In addition it provides a forum for the exchange of information on all aspects of cardiovascular imaging.
