Table 1

Relative advantages and disadvantages of the 4 atherosclerotic porcine models.

ModelAdvantagesLimitations

Diabetes/ hypercholesterolemicWell characterized.
Reproducible human-like atherosclerosis.
Results obtained from diagnostic and pharmacologic treatment studies corroborate data obtained in humans.
Complex lesions detectable as early as 6 months after induction.
Type I diabetic model.
Variable development of atherosclerosis.

Rapacz familial hypercholesterolemic Well characterized
Models a known human disease state.
Long induction period for atherosclerosis.
Large size of animals (although genetic modified mini-pig has been developed).
Expensive.

PCSK9 gain of function Small size.
Models a known human disease state.
Reproducible lesions.
Limited commercial availability.
Relatively long-term induction period (12 months).

Ossabaw Only model of metabolic syndrome induced atherosclerosis.
Small size.
Relatively short induction period after a high fat diet regimen.
Limited commercial availability.
