New Biomarkers and Plasma Prothrombotic Potential in Cardiac Transthyretin Amyloidosis
Assessment of the Association of New Biomarkers (GDF15, ST2, Galectin-3, TIMP-1, MMP-9, NfL) and Plasma Prothrombotic Potential in the Course of Cardiac Transthyretin Amyloidosis
The development of cardiac amyloidosis is caused by the deposition of misfolded, insoluble proteins in the extracellular matrix of tissues. An important element of the clinical picture of the disease is the increased risk of thromboembolic complications, independent of the occurrence of atrial fibrillation, and the presence of intracardiac thrombi. The pathomechanism may be related to an increase in filling pressure or amyloid infiltration leading to myocardial damage and endothelial dysfunction, which may activate the prothrombotic inflammatory cascade, resulting in increased thrombogenic potential. Currently, there is limited published data on the potential role of new heart failure biomarkers in the assessment of ATTR cardiomyopathy, particularly in the assessment of asymptomatic carriers of pathogenic TTR variants. Moreover, there are few literature reports on the direct assessment of the coagulation system in this group of patients, and the pathomechanism of the increased thromboembolic risk is unexplored.
Purpose of the study: To assess the diagnostic value of biomarkers related to heart failure (growth differentiation factor-15 (GDF15), soluble suppression of tumorigenicity-2 (ST2), galectin-3), amyloidosis ( TTR, tissue inhibitor of metalloproteinase-1 (TIMP-1), matrix metalloproteinase-9 (MMP-9, matrix metalloproteinase-9), neurofilament light chain (NfL)) and the generation potential thrombin as a marker of the prothrombotic state in the course of ATTR.
Methods: This prospective, single-center study will include consecutive patients diagnosed with ATTR cardiomyopathy (GROUP 1, n=30), asymptomatic carriers of pathogenic TTR variants (GROUP 2, n=30), and a matched control group of healthy volunteers (GROUP 3 , n=20). Material for research was collected and secured from all study participants. After giving informed consent, all patients will be tested using the ELISA method from peripheral blood (enzyme-linked immunosorbent assay) GDF15, ST2, TTR, TIMP-1, MMP-9, galectin-3, NfL. The values of these biomarkers will be compared in subgroups and correlated with clinical data, laboratory test results, echocardiography including analysis of left ventricular global strain (GLS), and scintigraphy. Additionally, the prothrombotic potential of plasma will be tested in both groups of patients using the calibrated automatic thrombogram (CAT) method, in accordance with the protocol previously used in the laboratory Expected results: The project will provide information on the value of biomarkers in the assessment of ATTR cardiomyopathy, especially in the assessment of asymptomatic carriers of pathogenic TTR variants, which may translate into the creation of a diagnostic algorithm for early identification of the development of the disease. Moreover, it will allow us to determine whether patients with cardiac ATTR are characterized by a prothrombotic state, which has not yet been described in the literature and may have potential clinical implications.

Detailed Description
Introduction: The development of cardiac amyloidosis is caused by the deposition of misfolded, insoluble proteins in the extracellular matrix of tissues. More than 30 precursor proteins can form amyloid fibrils, but two types account for 95% of cases of amyloid cardiomyopathy (CA): immunoglobulin light chain (AL) amyloidosis and transthyretin amyloidosis (ATTR). There are two forms of ATTR - acquired wild-type ATTR (ATTRwt) and the hereditary form (ATTRm), developing on the basis of mutations in the transthyretin (TTR) gene. Among patients with CA, as the disease progresses, heart failure develops, and if left untreated, the disease leads to death within 6 months to 3 years. Due to the unique pathology of the disease, the clinical picture includes the development of: peripheral polyneuropathy, autonomic dysfunction, and an increased risk of thromboembolic complications. An important element of the clinical picture of the disease is the increased risk of thromboembolic complications, independent of the occurrence of atrial fibrillation, and the presence of intracardiac thrombi. The pathomechanism may be related to an increase in filling pressure or amyloid infiltration leading to myocardial damage and endothelial dysfunction, which may activate the prothrombotic inflammatory cascade, resulting in increased thrombogenic potential. Scintigraphy has become a key technique in identifying patients with ATTR - in the absence of a detectable monoclonal protein, it allows for a non-invasive diagnosis of ATTR. Due to the development of disease-specific therapies (stabilizing drugs, gene therapy), it is important to diagnose the disease at an early stage, when the symptoms are relatively mild, and the implementation of treatment allows to stop the development of the disease and reduce mortality. Currently, there is limited published data on the potential role of new heart failure biomarkers in the assessment of ATTR cardiomyopathy, particularly in the assessment of asymptomatic carriers of pathogenic TTR variants. Moreover, there are few literature reports on the direct assessment of the coagulation system in this group of patients, and the pathomechanism of the increased thromboembolic risk is unexplored.
Purpose of the study: To assess the diagnostic value of biomarkers related to heart failure (growth differentiation factor-15 (GDF15), soluble suppression of tumorigenicity-2 (ST2), galectin-3), amyloidosis (TTR, tissue inhibitor of metalloproteinase-1 (TIMP-1), matrix metalloproteinase-9 (MMP-9, matrix metalloproteinase-9), neurofilament light chain (NfL)) and the generation potential thrombin as a marker of the prothrombotic state in the course of ATTR.
Methods: This prospective, single-center study will include consecutive patients diagnosed with ATTR cardiomyopathy (GROUP 1, n=30), asymptomatic carriers of pathogenic TTR variants (GROUP 2, n=30), and a matched control group of healthy volunteers (GROUP 3 , n=20). Material for research was collected and secured from all study participants. After giving informed consent, all patients will be tested using the ELISA method from peripheral blood (enzyme-linked immunosorbent assay) GDF15, ST2, TTR, TIMP-1, MMP-9, galectin-3, NfL. The values of these biomarkers will be compared in subgroups and correlated with clinical data, laboratory test results, echocardiography including analysis of left ventricular global strain (GLS), and scintigraphy. Additionally, the prothrombotic potential of plasma will be tested in both groups of patients using the calibrated automatic thrombogram (CAT) method, in accordance with the protocol previously used in the laboratory. The results will be compared with reference values for the control group. All tests will be performed by qualified and experienced staff.
Expected results: The project will provide information on the value of biomarkers in the assessment of ATTR cardiomyopathy, especially in the assessment of asymptomatic carriers of pathogenic TTR variants, which may translate into the creation of a diagnostic algorithm for early identification of the development of the disease. Moreover, it will allow us to determine whether patients with cardiac ATTR are characterized by a prothrombotic state, which has not yet been described in the literature and may have potential clinical implications. The obtained results can be used as starting data for further research on the coagulation system in ATTR in subsequent scientific projects.
