Abstract

Aortic stenosis (AS) and atherosclerosis are progressive cardiovascular conditions that frequently coexist and share multiple clinical and molecular features. Medical therapies have shown effectiveness in preventing and treating atherosclerosis and its consequences. For AS, effective pharmacological therapies remain limited. Understanding the shared risk factors and mechanisms between the two conditions may provide opportunities for therapeutic repositioning in AS. We performed a narrative review focusing on studies published from 2005 to 2025. Inclusion criteria encompassed clinical trials, experimental models, and molecular studies addressing overlapping risk factors, pathological pathways, and treatment approaches for AS and atherosclerosis. AS and atherosclerosis share key risk factors, including age, hypertension, hyperlipidemia, and diabetes. Molecular mechanisms, such as chronic inflammation, endothelial dysfunction, oxidative stress, lipid accumulation, and calcific remodeling, are common to both. Pathways involving the renin-angiotensin system, Notch signaling, and osteogenic mediators contribute to disease progression. Several drug classes, notably proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, lipoprotein(a) (Lp(a)) lowering therapies, anti-inflammatory agents, and immunomodulators, show potential for repositioning in AS management. The substantial overlap in risk factors and molecular mechanisms between AS and atherosclerosis supports a rationale for therapeutic repositioning. Targeting shared pathways could lead to innovative strategies for slowing AS progression and improving patient outcomes.
