Implication
SHFM shows modest discrimination and early survival overestimation in CRT; leaves open need for therapy-specific risk models.

Does the Seattle Heart Failure Model accurately predict mortality risk in patients treated with cardiac resynchronization therapy?
P
Population
1,139 consecutive patients treated with cardiac resynchronization therapy (CRT) analyzed retrospectively from five centres.
I
Intervention
Seattle Heart Failure Model (SHFM) for mortality risk prediction
O
Outcome
Survival/mortality at 1, 2, and 5 yearshard clinical
The Seattle Heart Failure Model demonstrates modest performance in predicting survival for CRT patients, tending to overestimate survival while still identifying a high-risk subgroup.
