    Background: Autonomic function can be evaluated based on the pupillary light reflex (PLR). However, the relationship between PLR and prognosis in patients with heart failure (HF) remains unclear. This study was performed to examine whether PLR could be used as a prognostic indicator in patients with HF. Methods and Results: A retrospective review was performed in 535 consecutive Japanese patients hospitalized for acute HF (mean age 66.1 ± 13.7 y). PLR was recorded at least 7 days after hospitalization for HF with the use of a pupilometer. Fifty-three patients died over a median follow-up period of 1.3 years (interquartile range 0.6–2.3 y). After adjustment for several preexisting prognostic factors, including Seattle Heart Failure Score (SHFS), PLR as assessed by recovery time (time to 63% redilation) was independently associated with all-cause mortality (hazard ratio 0.50, 95% confidence interval 0.35–0.73; P <.001). The addition of recovery time to SHFS resulted in a significant increase in the area under the curve on receiver-operating characteristic curve analysis (0.69 vs 0.77; P <.001). Conclusions: PLR assessed by recovery time was an independent predictor of mortality and added prognostic information to the SHFS in patients with HF. Our results suggest that PLR may be useful as a new prognostic marker in HF patients.
