Key Points

  • Economic evaluation of the Mediterranean diet for patients following first AMI (acute myocardial infarction).

  • A cost utility analysis was conducted, using a Markov model to describe health status, costs, quality of life and deaths to compare the Mediterranean diet to a prudent Western diet.

  • Program effectiveness was based on the Lyon Diet Heart Study.

  • Costs were estimated in $AU, (and converted to $US and €Euros) based on reported resource use.

  • Performance was measured as cost per quality adjusted life year (QALY) gained.

  • Extensive one-way sensitivity analyses were performed.

  • The Mediterranean diet was estimated to cost less and be more effective (dominant) compared with a prudent Western diet.

  • There was a mean gain in life years of 0.56 per person and a gain in quality adjusted life years of 0.61 per person.

  • Based on the published results from the Lyon Diet Heart Study, and conservative assumptions, the Mediterranean diet is cost saving for persons following first AMI when modeled over 10 years.

  • Policy makers and clinicians should strongly consider application of results to their own setting.
