Prediction of Mortality and Morbidity With a 6-Minute Walk Test in Patients With Left Ventricular Dysfunction
Why the study?
Does 6-minute walk test performance predict mortality and hospitalization in patients with left ventricular dysfunction?
Population
898 patients with left ventricular dysfunction from the SOLVD Registry Substudy
Comparison
6-minute walk test (lowest performance level) vs 6-minute walk test (highest performance level)
Design
Cohort
Follow-up

Implication
Supports 6MWT for risk stratification in LV dysfunction; leaves open incremental value beyond LVEF in prospective studies.
Structured PICO
Does 6-minute walk test performance predict mortality and hospitalization in patients with left ventricular dysfunction?
P
Population
898 patients with left ventricular dysfunction (radiological evidence of congestive heart failure and/or ejection fraction ≤0.45) from the SOLVD Registry Substudy
I
Intervention
6-minute walk test (lowest performance level)
C
Comparator
6-minute walk test (highest performance level)
O
Outcome
Mortality and hospitalizationhard clinical
The 6-minute walk test is a simple, safe, and independent predictor of mortality and heart failure hospitalization in patients with left ventricular dysfunction, performing comparably to ejection fraction.
