AI Article Synopsis

  • Cardiac amyloidosis is a rare condition where abnormal proteins deposit in the heart, leading to heart failure due to restrictive cardiomyopathy.
  • A specific case highlights how cardiac amyloidosis can reveal underlying multiple myeloma in patients without prior heart issues.
  • Key signs to identify it include unexplained heart failure symptoms, specific ECG findings, preserved ejection fraction, and unique echocardiogram texture, with a focus on vigilant monitoring due to high mortality risk.

Article Abstract

Cardiac amyloidosis or amyloid cardiomyopathy is a rare disorder characterised by extracellular deposition of insoluble polymers composed of low-molecular-weight subunit proteins within the myocardium. This often results in an infiltrative cardiomyopathy with restrictive pathophysiology, leading to progressive heart failure. In this report, we present an interesting case of cardiac amyloidosis that eventually led to the diagnosis of underlying multiple myeloma in a patient with no previous cardiac history. Cardiac amyloidosis should be suspected in patients with unexplained congestive heart-failure symptoms accompanied by low-voltage complexes on ECG, preserved ejection fraction with asymmetric ventricular hypertrophy and abnormal myocardial texture, described as 'granular sparkling' on echocardiogram. Patients with cardiac amyloidosis should be closely monitored as mortality remains high, despite advances in treatment.

Improving prognostic evaluations in patients with stage IIIb light chain cardiac amyloidosis: role of haemodynamic parameters.

Orphanet J Rare Dis

January 2025

Department of Cardiology, State Key Laboratory of Complex Severe and Rare Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, No. 1 Shuaifuyuan, Dongcheng District, Beijing, 100730, China.

Background: There is no unified prognostic scoring system for light chain cardiac amyloidosis (AL-CA), particularly stage IIIb AL-CA. This study aimed to use invasive haemodynamic information to investigate markers that can more accurately evaluate the prognosis of patients with stage IIIb AL-CA.

Methods: In this retrospective cohort study, we conducted invasive haemodynamic measurements concurrently with myocardial biopsies to diagnose AL-CA.

There is no established treatment for late or chronic antibody-mediated rejection of a kidney graft. Rituximab-based treatment is not effective, since long-lived high-affinity plasma cells do not express CD20 and do not depend on previous maturation steps to generate donor-specific antibodies. Conversely, daratumumab, an anti-CD38 monoclonal antibody, directly targets plasma cells, with proven efficacy in multiple myeloma.

Objective: Tafamidis has shown potential in slowing disease progression in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). This study aimed to evaluate serial changes on [Tc]Tc-pyrophosphate (PYP) scintigraphy during tafamidis treatment for hereditary ATTR-CM.

Methods: We retrospectively analyzed a prospectively collected cohort of Ala97Ser (A97S) hereditary ATTR-CM patients treated with tafamidis (61 mg/day) and a control group comprising A97S hereditary ATTR-CM patients who had not received disease-modifying medications.

Cardiac amyloidosis represents a unique disease process characterized by amyloid fibril deposition within the myocardial extracellular space. Advances in multimodality cardiac imaging enable accurate diagnosis and facilitate prompt initiation of disease-modifying therapies. Furthermore, rapid advances in multimodality imaging have enriched understanding of the underlying pathogenesis, enhanced prognostication, and resulted in the development of imaging-based markers that reflect the amyloid burden, which is of increasing importance when assessing the response to treatment.

Molecular Stratification of Light-Chain Cardiac Amyloidosis With F-Florbetapir and Ga-FAPI-04 for Enhanced Prognostic Precision.

Background: Cardiac involvement in amyloid light chain (AL) amyloidosis significantly influences prognosis, necessitating timely diagnosis and meticulous risk stratification.

Objectives: This prospective study aimed to delineate the molecular phenotypes of AL cardiac amyloidosis (AL-CA) by characterizing fibro-amyloid deposition using F-florbetapir and gallium-68-labeled fibroblast activation protein inhibitor-04 (Ga-FAPI-04) positron emission tomography (PET)/computed tomography (CT) imaging. The authors also proposed a novel molecular stratification methodology for prognosis.
