Duke University researchers recently investigated the effect that positive outlook can have on cardiac patients’ longevity. In a new study published in the Archives of Internal Medicine, researchers found that cardiac patients who had positive outlooks about the future lived longer than patients with negative outlooks. Researchers discovered the association even after controlling for the differences in how sick the patients were, said Dr. John Barefoot, an author of the study.

The study doesn’t explain why patients with higher expectations lived longer, but Barefoot said one explanation could be that patients might be more likely to follow through with their doctor’s instructions, such as eating healthfully, exercising and taking medications.
