Does lowering cholesterol have an impact on the progression of aortic stenosis?

Area of Science:

• Cardiovascular Medicine
• Atherosclerosis Research
• Valvular Heart Disease

Background:

• Atherosclerotic disease is increasingly recognized as a systemic condition, not limited to specific arterial sites.
• Calcific aortic stenosis (AS) shares pathological similarities with vascular atherosclerosis, suggesting potential for shared treatment strategies.

Purpose of the Study:

• To review the pathophysiology of calcific AS.
• To evaluate current and ongoing clinical trials on statin therapy for AS.
• To explore patient stratification methods for statin therapy in AS.

Main Methods:

• Review of pathophysiological mechanisms in calcific AS.
• Analysis of current and ongoing clinical trials investigating statin use in AS patients.
• Examination of diagnostic tools (CT, biomarkers) and clinical factors (LVEF) for patient stratification.

Main Results:

• The review synthesizes evidence on the atherosclerotic nature of AS.
• It highlights ongoing trials assessing statins' efficacy in slowing AS progression.
• Potential roles for imaging and biomarkers in guiding therapy are discussed.

Conclusions:

• Calcific AS shares mechanisms with atherosclerotic vascular disease, opening avenues for novel therapeutic approaches.
• Cholesterol-lowering therapies, like statins, are under investigation for their potential to modify AS progression.
• Further research is needed to identify patient subgroups who may benefit most from statin therapy in AS.
