Key result
High-cholesterol diet cuts aortic valve elastin ~32% vs. control in rabbits.
Why the study?
It is not known whether early atherosclerosis induces ultrastructural changes in the elastic laminae of the cardiac aortic valve.
Does a high cholesterol diet induce ultrastructural changes in the elastic laminae of the aortic valve in rabbits?
Population
10 rabbits
Comparison
High cholesterol diet vs control diet
Design
Preclinical experimental study

May signal early valve involvement in atherosclerosis; leaves open human translation and clinical relevance.
Does a high cholesterol diet induce ultrastructural changes in the elastic laminae of the aortic valve in rabbits?
Absolute Event Rate: 29.03% vs 42.94%
p-value: p=0.023
Experimental hypercholesterolemia in rabbits induces early atherosclerotic ultrastructural changes and elastin degradation in the aortic valve.
Kwon et al. (1998) studied Hypercholesterolemia (n=10). High cholesterol diet vs. Control diet was evaluated on Percentage of elastin content in the arterialis elastic laminae (p=0.023). A high cholesterol diet significantly decreased the elastin content in the arterialis elastic laminae of rabbit aortic valves compared to a control diet (29.03% vs. 42.94%, p=0.023).
