Cardiac amyloidosis, increasingly recognized for its significant impact on global heart health and patient survival, demands a thorough review to understand its complexity and the urgency of improved management strategies. As a cause of cardiomyopathy and heart failure, particularly in patients with aortic stenosis and atrial fibrillation, this condition also relates to higher incidences of dementia in the affected populations. The objective of this review was to integrate and discuss the latest advancements in diagnostics and therapeutics for cardiac amyloidosis, emphasizing the implications for patient prognosis. We evaluated the latest literature from major medical databases such as PubMed and Scopus, focusing on research from 2020 to 2024, to gather comprehensive insights into the current landscape of this condition. Insights from our review highlight the complex pathophysiology of cardiac amyloidosis and the diagnostic challenges it presents. We detail the effectiveness of emerging treatments, notably gene silencing therapies like patisiran and vutrisiran, which offer transformative potential by targeting the production of amyloidogenic proteins. Additionally, the stabilization therapy acoramidis shows promise in modifying disease progression and improving clinical outcomes. This review underscores the critical need for updated clinical guidelines and further research to expand access to groundbreaking therapies and enhance disease management. Advocating for continued research and policy support, we emphasize the importance of advancing diagnostic precision and treatment effectiveness, which are vital for improving patient outcomes and addressing this debilitating disease globally.

AF is a common arrhythmia in cardiomyopathy, particularly when congestive heart failure is present. The neurohormonal activation in congestive heart failure may trigger fibrotic and other changes in the left atrium and the atrial stretch associated with heart failure may induce further atrial pathology and/ or directly trigger AF (8). By the time that patients with AF develop extensive fibrosis, the arrhythmia has been shown to be associated with a greater difficulty in maintaining sinus rhythm despite attempted ablation procedures.

Transthyretin Cardiac amyloidosis (ATTR-CA) is an increasingly recognised cause of heart failure in our elderly patients with preserved ejection fraction. Patients with ATTR-CA who require permanent pacemaker implantation often have preserved ejection fraction and do not meet the clinical indication for cardiac resynchronization therapy (CRT). In these patients, left bundle branch area pacing (LBBAP) can be a reasonable option to maximise physiological activation of the left ventricle.

Hereditary transthyretin amyloidosis (ATTRv, v for variant) is a genetic disorder characterized by the deposition of misfolded transthyretin (TTR) protein in tissues, resulting in progressive dysfunction of multiple organs, including the nervous system, heart, kidneys, and gastrointestinal (GI) tract. Noninvasive serum biomarkers have become key tools for diagnosing and monitoring ATTRv. This review examines the role of available biomarkers for neurological, cardiac, renal, gastrointestinal, and multisystemic involvement in ATTRv.

Background: Genome-wide association studies (GWAS) in Alzheimer's disease (AD) leveraging endophenotypes beyond case/control diagnosis, such as brain amyloid β pathology, have shown promise in identifying novel variants and understanding their potential functional impact. In this study, we leverage two brain amyloid β pathology measurement modalities, PET imaging and neuropathology, to address sample size limitations and to discover novel genetic drivers of disease.
Method: We conducted a meta-analysis on an amyloid PET imaging GWAS (N = 7,036, 35% amyloid positive, 53.

Background: FDA-approved carbonic anhydrase inhibitors (CAIs) have been shown to attenuate Aβ pathology, neurodegeneration, and cerebrovascular dysfunction in models of Alzheimer's disease (AD) and cerebral amyloid angiopathy (CAA), suggesting a key role for CAs as a novel and previously unexplored target for AD therapy. Amyloid β accumulation severely impairs the cerebral neuro-signaling pathway with a progressive loss in neurotrophic factors (NTFs, i.e.
