Researcher from Duke University, Medical Center in Chapel Hill, North Carolina, gave 2818 heart disease patients a coronary angiography to evaluate blood flow in the heart. Patients were then tracked for approximately 15 years to determine whether outlook had an effect on physical health and survival. After 15 years, 1637 people had died, and 54% of the deaths were due to cardiovascular disease.
The higher risk of death for those with more negative outlooks remained after controlling for age, gender, income and other factors. These findings demonstrate the magnitude of the impact of patient expectations on the recovery process above, beyond depression and other psychological or social status.
Heart patients with a positive outlook regarding their recovery were 30% less likely to die over the next 15 years than patients with less optimistic expectations, regardless of the severity of their symptoms.
