Abstract

Introduction: Cardiac Amyloidosis (CA) is characterised by amyloid fibril deposits causing heart failure (HF). Lumbar spinal stenosis (LSS) is recognised as a potential red flag for CA, but the association remains underexplored in large-scale studies.

Methods: This nationwide registry-based cohort study in Denmark included subjects ≥60 years with a history of LSS surgery. LSS patients were matched 1:1 with controls by age, sex, ischaemic heart disease, chronic obstructive lung disease, chronic kidney disease, diabetes, and atrial fibrillation.

Results: A total of 44,548 LSS surgery patients and matched controls were included (median age 71.5 years, 56.2% women). The cumulative incidence of amyloidosis after 10 years was higher in the LSS group (0.16% vs. 0.08%, HR 2.29 [95% CI 1.46-3.60]) after adjustment for malignancy, hypertension, and liver disease. The cumulative incidence of HF after 10 years was 10.1% in LSS patients compared with 7.5% in controls (HR 1.28 [95% CI 1.22-1.35], p < 0.0001).

Conclusions: In this nationwide cohort study, LSS surgery was associated with a significantly higher risk of amyloidosis and HF. Prospective studies are warranted to explore the association further.

期刊介绍： Amyloid: the Journal of Protein Folding Disorders is dedicated to the study of all aspects of the protein groups and associated disorders that are classified as the amyloidoses as well as other disorders associated with abnormal protein folding. The journals major focus points are: etiology, pathogenesis, histopathology, chemical structure, nature of fibrillogenesis; whilst also publishing papers on the basic and chemical genetic aspects of many of these disorders. Amyloid is recognised as one of the leading publications on amyloid protein classifications and the associated disorders, as well as clinical studies on all aspects of amyloid related neurodegenerative diseases and major clinical studies on inherited amyloidosis, especially those related to transthyretin. The Journal also publishes book reviews, meeting reports, editorials, thesis abstracts, review articles and symposia in the various areas listed above.
