Understanding of Prognosis and Estimation of Mortality in Ambulatory Patients With Heart Failure

How well do ambulatory patients with high-risk heart failure (HF) with reduced ejection fraction estimate their own survival compared with a validated, guideline-endorsed risk score, and is overestimation associated with mortality?In this cohort study of 296 patients with chronic HF, 33% overestimated their life expectancy by more than 50% compared with model estimates, and such overestimation was associated with higher mortality in the subsequent 2 years.The findings suggest improving patient understanding of prognosis may enhance shared decision-making for patients with high-risk ambulatory HF.
