Dean Ornish
b. 1953 · United States · Integrative Medicine, Medicine
Proved lifestyle change can reverse coronary artery disease; first such programme reimbursed by Medicare.
Core concepts
- Comprehensive lifestyle change as treatment, not merely prevention
- Reversal of coronary atherosclerosis without drugs or surgery
- Four-part programme: whole-food plant-based diet, exercise, stress management, social support
Key writings and teachings
- Dr. Dean Ornish's Program for Reversing Heart Disease (1990)
- The Lifestyle Heart Trial, The Lancet (1990) and JAMA five-year follow-up (1998)
- Undo It! (2019) and prostate-cancer and telomerase lifestyle studies
Influence on modern practice
The Lifestyle Heart Trial produced angiographic evidence that intensive lifestyle change can regress coronary stenosis, and Ornish's programme became the first lifestyle intervention granted Medicare reimbursement as intensive cardiac rehabilitation. It is delivered in hospital systems across the United States; critics note small samples and the difficulty of isolating which component works.
