In Reply: Our study was designed to quantify miscalibration of patient predictions of survival in comparison with objective model predictions. The reasons underlying the overestimation of life expectancy by many patients with heart failure remain unknown. Our limited findings suggest age, depression, education, and other factors are all likely to play a role in patient perceptions of prognosis and thus in the personal choices made by symptomatic heart failure patients regarding their medical care.
