The Prognostic Value of Serial Six-Minute Walk Testing for Mortality Prediction in Heart Failure Patients

Key Points

• Both absolute walking distance and improvement over time independently predict mortality in heart failure patients.
• Serial six-minute walk testing provides significant prognostic value beyond initial assessments.
• Modeling functional trajectories over time enhances mortality risk predictions, facilitating tailored clinical strategies.
• Effective clinical management relies on understanding these prognostic factors for better patient outcomes.
