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.
This study will examine the clinical effectiveness of Tafamidis in patients with Mixed Phenotype Hereditary Transthyretin Amyloidosis using data that already exist in patients' medical records.
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.
Cardiac amyloidosis is a condition where the heart muscle, amongst other tissues, is infiltrated by the abnormal build-up of proteins called amyloid. This stiffens and thickens the heart muscle over time which makes it less efficient and puts further stress and strain on the other chambers of the heart, leading to heart failure. The commonest form, that affects predominantly the elderly, is called 'wild-type' ATTR amyloid (TTR is the protein that accumulates). In this condition a patient has a 60% chance of admission to hospital each year after diagnosis. There is no current treatment for ATTR amyloid other than using water tablets to reduce excess fluid and prevent more serious fluid build up in lungs and other tissues. Increasing body weight is the most reliable clinical sign of this fluid build up. Tele-monitoring is the practice of monitoring patients from a distance and has been shown to reduce heart failure admissions and death in patients with heart failure from any cause. Due to reduced access to primary and secondary care during COVID-19 the investigators instigated tele-monitoring of heart failure in ATTR amyloid patients. This appeared to be an effective intervention in the pilot study. The investigators propose to monitor the weight of patients with cardiac amyloidosis at home and intervene where a build up of fluid is observed by telephone discussion with a doctor. The investigators propose to evidence this in a prospective clinical trial. The investigators will evaluate the effect fairly by comparing tele-monitoring with usual care.
Cerebral Amyloid Angiopathy (CAA) is one form of disease of the small vessels of the brain and can cause frequent cerebral hemorrhages as well as other types of stroke. The aim of the research was to examine the balance of the body in patients after a stroke and to determine how the tension of selected muscles of the cervical spine changes under the conditions of statics and dynamics, depending on the visual control or its absence.
Transthyretin amyloidosis (aTTR) initially described as a rare disease, became the most serious hereditary polyneuropathy of adult onset and family screening has made it possible to identify and follow up many asymptomatic patients and carriers of the mutation in the TTR gene. Considered as a systemic disease with involvement of target organs (the heart, the eye, the kidney and peripheral nervous system), it seems to be more complex for neurologists according to recent publications raising the issue of central nervous system involvement. Indeed, TTR amyloid deposits seem to be correlated with the duration of the disease. These deposits can cause cortical damage by different mechanisms: direct TTR toxicity or as a result of pathology related to cerebral amyloid angiopathy (intraparenchymal or subarachnoid hematomas, small infarcts, hemosiderin). A small number of mutations in the TTR gene cause a rare phenotype of systemic amyloidosis, the oculoleptomeningeal form, characterized by clinical neurological symptoms: progressive dementia, epilepsy, ataxia, spastic paraparesis, stroke-like episodes. Hypothesis of the work: the central nervous system involvement is probably underestimated on the radiological description in patients with TTR mutation.
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).
