Deep Spatio-temporal Sparse Decomposition for Trend Prediction and Anomaly Detection in Cardiac Electrical Conduction [PDF]

arXiv, 2021
Electrical conduction among cardiac tissue is commonly modeled with partial differential equations, i.e., reaction-diffusion equation, where the reaction term describes cellular stimulation and diffusion term describes electrical propagation. Detecting and identifying of cardiac cells that produce abnormal electrical impulses in such nonlinear dynamic ...

Natural history and outcome in systemic AA amyloidosis [PDF]

, 2007
BACKGROUND:Deposition of amyloid fibrils derived from circulating acute-phase reactant serum amyloid A protein (SAA) causes systemic AA amyloidosis, a serious complication of many chronic inflammatory disorders.

Unveiling outcomes in coexisting severe aortic stenosis and transthyretin cardiac amyloidosis

European Journal of Heart Failure, 2020
Advances in diagnostic imaging have increased the recognition of coexisting transthyretin cardiac amyloidosis (ATTR‐CA) and severe aortic stenosis (AS), with a reported prevalence between 8–16%.

Transthyretin amyloid cardiomyopathy in aortic stenosis patients scheduled for transcatheter aortic valve implantation

ESC Heart Failure, EarlyView.
Abbreviations: TAVI, transcatheter aortic valve implantation; ATTR‐CM, transthyretin cardiac amyloidosis. We aimed to diagnose occult ATTR‐CM in patients with severe aortic stenosis undergoing TAVI using bone scintigraphy. We verified a diagnosis of ATTR‐CM in 8 of 171 (4.7 %) consecutive aortic stenosis patients who underwent TAVI.

Technetium-99m pyrophosphate cardiac SPECT in endomyocardial biopsy negative cardiac amyloidosis

Radiology Case Reports, 2018
Cardiac amyloidosis is an under-appreciated cause of heart failure. Establishing a diagnosis is important because traditional heart failure treatment regimens can worsen left ventricular failure in this disease. Endomyocardial biopsy is the gold standard

Prospects for AI-Enhanced ECG as a Unified Screening Tool for Cardiac and Non-Cardiac Conditions -- An Explorative Study in Emergency Care [PDF]

arXiv, 2023
Current deep learning algorithms designed for automatic ECG analysis have exhibited notable accuracy. However, akin to traditional electrocardiography, they tend to be narrowly focused and typically address a singular diagnostic condition. In this exploratory study, we specifically investigate the capability of a single model to predict a diverse range

Misdiagnosis of hereditary amyloidosis as AL (Primary) amyloidosis [PDF]

, 2002
Background: Hereditary, autosomal dominant amyloidosis, caused by mutations in the genes encoding transthyretin, fibrinogen A -chain, lysozyme, or apolipoprotein A-I, is thought to be extremely rare and is not routinely included in the differential ...

Cardiac Amyloidosis: Overlooked, Underappreciated, and Treatable.

Annual Review of Medicine, 2020
Cardiac amyloidosis (CA) is an infiltrative and restrictive cardiomyopathy that leads to heart failure, reduced quality of life, and death. The disease has two main subtypes, transthyretin cardiac amyloidosis (ATTR-CA) and immunoglobulin light chain ...

Plasma metabolomics identifies signatures that distinguish heart failure with reduced and preserved ejection fraction

ESC Heart Failure, EarlyView.
Abstract Aims Two general phenotypes of heart failure (HF) are recognized: HF with reduced ejection fraction (HFrEF) and with preserved EF (HFpEF). To develop phenotype‐specific approaches to treatment, distinguishing biomarkers are needed. The goal of this study was to utilize quantitative metabolomics on a large, diverse population to replicate and ...
