Key result
A pro-atherosclerotic diet, with or without intraaortic balloon injury, successfully induced high aortic calcific plaque burden in rabbits after 3 and 6 months (p<0.0001 for calcification).
Why the study?
Evaluating the hemodynamic impact of extracorporeal circulation on atheromatous plaques requires an atherosclerosis animal model that is also eligible for extracorporeal circulation.
p-value: p=<0.0001
A rabbit model of atherosclerosis can be effectively induced by a pro-atherosclerotic diet alone, without the need for balloon injury, providing a suitable model for studying extracorporeal circulation.

Simplifies rabbit atherosclerosis induction for research; leaves open translation to human extracorporeal circulation studies.
Assmann et al. (2025) studied Atherosclerosis (n=29). Pro-atherosclerotic diet with or without intraaortic balloon insufflation injury vs. Control diet was evaluated on Atherosclerotic plaque development (cholesterol levels, inflammatory infiltration, intima hyperplasia, calcification) (p=<0.0001). A pro-atherosclerotic diet, with or without intraaortic balloon injury, successfully induced high aortic calcific plaque burden in rabbits after 3 and 6 months (p<0.0001 for calcification).
