Filter by:Despite rapidly advancing developments in targeted therapeutics and genetic sequencing, persistent limits in the accuracy and throughput of clinical phenotyping has led to a widening gap between the potential and the actual benefits realized by precision medicine. Recent advances in machine learning and image processing techniques have shown that machine learning models can identify features unrecognized by human experts and more precisely/accurately assess common measurements made in clinical practice. The investigators have developed an algorithm, termed EchoNet-LVH, to identify cardiac hypertrophy and identify patients who would benefit from additional screening for cardiac amyloidosis and will prospectively evaluate its accuracy in identifying patients whom would benefit from additional screening for cardiac amyloidosis.
Anginal symptoms and signs of ischemia have been reported in some patients with cardiac amyloidosis (TTR) without obstructive epicardial coronary artery disease (CAD). It was found that coronary microvascular dysfunction was highly prevalent in subjects with cardiac amyloidosis, even in the absence of epicardial CAD. The investigators found lower stress and rest myocardial blood flow (MBF) and lower myocardial flow reserve (MFR) in their cardiac PET (Positron emission tomography) study (13N), including 21 patients. The advances in SPECT technology including cadmium zinc telluride (CZT) detectors allow to evaluate the MBF and MFR estimation by SPECT as shown in both experimental animal models and also in clinical studies with comparison to PET. SPECT is more widely available than cardiac PET. Thus, the investigators would like: 1. to confirm the results of Dorbala et al using SPECT, and 2. to go further with evaluation of the effect of Tafamidis on microvascular dysfunction.
This is a non-interventional, prospective, retrospective, non-comparative, multi-center study. In order not to interfere with patient management, the study is observational. Thus, no follow-up visit is imposed. The data collection will be limited to the data related to the management of the patients included throughout their follow-up. This study is intended for all patients with a confirmed or suspected diagnosis of cardiac amyloidosis. Three cohorts will be identified: the HEAR (Healthcare European Amyloidosis Registry)-Retrospective Cohort, the HEAR(Healthcare European Amyloidosis Registry)-Retrospective-Prospective Cohort and the HEAR (Healthcare European Amyloidosis Registry)-Prospective Cohort.
The purpose of this study is to evaluate the safety and tolerability of extended dosing with Eplontersen in participants with hereditary transthyretin-mediated amyloid polyneuropathy (hATTR-PN).
This phase 2 study ain to evaluate the efficacy of Isatuximab plus Pomalidomide and Dexamethasone (IPd), in patients with AL amyloidosis not in VGPR or better after any previous therapy. It will enrolled 46 patients (34 in France and 12 in Australia) through 15 sites (11 in France and 4 in Australia).
The purpose of this study is to collect and evaluate pregnancy outcomes, pregnancy complications, and fetal/neonatal/infant outcomes in women exposed to patisiran-LNP.
To evaluate the efficacy and safety of patisiran in patients with wtATTR amyloidosis and symptomatic polyneuropathy by evaluating the effect on neurologic impairment and quality of life.
The study team will generate preliminary data on whether patients with cardiac amyloidosis feel better when their beta-blocker is stopped. To achieve this objective, 20 N-of-1 trials (on vs. off) will be conducted, and the study team will subsequently interview participants to better understand their outcomes. Each subject will participate in 2 periods lasting between up to 6 weeks each based on each patient's health profile. We will also engage stakeholders to understand the acceptability and feasibility of deprescribing N-of-1 trials. The N-of-1 trials will be iteratively refined in real-time based on feedback.
Due to a lack of therapeutic options, the diagnosis of cardiac (wt)-ATTR amyloidosis was for a long time overshadowed by other diseases and therefore was or still is often diagnosed with considerable delay. The aim of the study is to estimate the prevalence of cardiac amyloidosis among patients with mild-to-moderate aortic valve stenosis (AS). Besides that a screening algorithm based on echocardiographic parameters will be developed, to facilitate the early detection of cardiac amyloidosis.
The goal of this study to investigate if exercise predisposes to transthyretin instability. The investigators will evaluate the effect of exercise on transthyretin biochemistry.
