Filter by:This is a single center, diagnostic clinical trial in which the investigators aim to prospectively validate a deep learning model that identifies patients with features suggestive of cardiac amyloidosis, including transthyretin cardiac amyloidosis (ATTR-CA). Cardiac Amyloidosis is an age-related infiltrative cardiomyopathy that causes heart failure and death that is frequently unrecognized and underdiagnosed. The investigators have developed a deep learning model that identifies patients with features of ATTR-CA and other types of cardiac amyloidosis using echocardiographic, ECG, and clinical factors. By applying this model to the population served by NewYork-Presbyterian Hospital, the investigators will identify a list of patients at highest predicted risk for having undiagnosed cardiac amyloidosis. The investigators will then invite these patients for further testing to diagnose cardiac amyloidosis. The rate of cardiac amyloidosis diagnosis of patients in this study will be compared to rate of cardiac amyloidosis diagnosis in historic controls from the following two groups: (1) patients referred for clinical cardiac amyloidosis testing at NewYork-Prebysterian Hospital and (2) patients enrolled in the Screening for Cardiac Amyloidosis With Nuclear Imaging in Minority Populations (SCAN-MP) study.
Patients operated for carpal tunnel syndrome (CTS) at Ålesund Hospital (200 patients) will have a biopsy to diagnose ATTR amyloidosis. Patients with positive biopsy will be examined to decide wether they have cardiac amyloidosis. All patients with positive biopsy will be followed closely for 10 years wit echocardiography an clinically.
Tne aim purpose of this observational, multicentre and propective study is to determine the prevalence of cardiac amyloidosis in geriatric patients aged 80 years and older hospitalized within the last 12 months for heart failure with left ventricular hypertrophy (septum ≥ 12 mm) on echocardiography
Notwithstanding the dramatic improvement associated with Tafamidis in Heart Failure (HF) due to wild-type transthyretin cardiac amyloidosis (ATTRwt-CA), remarkable morbidity and mortality still burden this disease. Exercise training (ET) is a first-line recommended treatment for unselected HF patients, whose effects on ATTRwt-CA form remain however unexplored. The investigators hereby present rationale and design of the Exercise training and Rehabilitation in Cardiac Amyloidosis (ERICA) study, whose aim is to determine whether a tailored, supervised ET program might improve exercise capacity in HF due to ATTRwt-CA. This interventional, controlled study will randomize ATTRwt-CA patients into a control group (C) and a primary training group (ET-1). After 12 weeks, patients in group C will be offered to undergo the same ET program (ET-2) for further 12 weeks, considering the last observation as baseline. Primary endpoint will be the distance obtained at the 6-minute walk test (6MWD) performed at baseline and after 12-weeks of treatment in pooled ET-1 and ET-2 groups compared to C. Quality of life, peak oxygen consumption, left and right heart architecture and function, natriuretic peptides will be secondary endpoints. This study will be the first testing the effects of ET in patients with ATTRwt-CA.
Cardiac amyloidosis (CA) has recently been reported as a common cause of heart failure with preserved left ventricular ejection fraction (HFpEF), with a prevalence of 6% in elderly HFpEF patients. However, the diagnosis of CA is still challenging and requires multiple costly investigations. Regardless of the type of CA, TTR or AL, early diagnosis significantly improves prognosis. In this study, the investigators aimed to determine the prevalence of CA in Tunisian HFpEF patients and to identify clinical and ultrasound criteria predictive of CA.
Demonstrate the beneficial impact of three targeted Shiatsu sessions versus "comfort" Shiatsu on symptoms in cardiac amyloidosis patients with severe symptoms. To demonstrate the beneficial short-term impact of a targeted SHIATSU session on neuro-cardio-vascular physiological parameters and symptoms in patients with cardiac amyloidosis compared with comfort Shiatsu and no Shiatsu. To demonstrate the beneficial impact of three targeted Shiatsu sessions versus "comfort" Shiatsu and no Shiatsu on symptoms (fatigue, sleep, pain, anxiety, depression dyspnea, digestive disorders, nausea) and quality of life in cardiac amyloidosis patients with severe symptoms. Evaluate patient satisfaction with shiatsu. Assess tolerance to shiatsu.
This single-practice prospective cohort study aims to enhance the diagnosis of cardiac amyloidosis in high-risk patients undergoing standard cardiac device implantation. By analyzing chest wall fat tissue, which is usually discarded, we aim to determine the diagnostic yield of such biopsies for amyloidosis and to develop a predictive screening model based on clinical, lab, and imaging data. The study, running from December 2023 to December 2024, expects to enroll 100 patients and may provide a new, non-invasive diagnostic avenue for this condition.
The study aims to test and compare the diagnostic yield of different diagnostic modalities (speckle tracking echocardiography, CMR, serum and urine protein analysis and bone tracer scintigraphy) in the detection of cardiac amyloidosis among patients with "red flags" suspecting cardiac amyloidosis.
This is a clinical registry of patients with cardiac amyloidosis being treated at University Hospital Leipzig. The aim of the registry is to collect detailed information about clinical events, symptoms, imaging, biomarkers, comorbidities, and treatment from routine patient management which would not be provided by randomized clinical trails.
The dual pathology of aortic stenosis (AS) and cardiac amyloidosis (CA) is increasingly recognized. Even tough efforts have been undertaken to bring cohorts together, the largest cohort of AS-ATTR to date is <50 patients. It is the aim of the present international, multi-center registry to collect ~300 patients with AS-CA creating a big enough cohort to allow 1. thorough characterization of this condition 2. assessment of log-term clinical outcomes of AS-CA 3. assessment of effectiveness of amyloid-specific treatment on top of valve replacement
