Key result
Among patients undergoing cardiac resynchronization therapy, 32.7% survived longer than 10 years, with baseline variables predicting long-term survival with an area under the curve of 0.816.
Why the study?
While predictors of LV remodeling and short-term mortality after CRT are known, limited data exist on long-term outcomes after CRT placement.
Cohort (n=877)
No
Nearly one-third of patients with LVEF ≤35% undergoing CRT implantation survive beyond 10 years, and baseline clinical variables can accurately predict this long-term survival.
No takes yet. Share an insight, caveat, or question.
Identifies long-term CRT survivors via baseline variables; leaves open whether model-guided selection improves outcomes prospectively.
Patel et al. (2020) conducted a cohort in Medically refractory heart failure (n=877). Cardiac resynchronization therapy (CRT) implantation was evaluated on Survival or freedom from LVAD or heart transplant for longer than 10 years after CRT implantation. Among patients undergoing cardiac resynchronization therapy, 32.7% survived longer than 10 years, with baseline variables predicting long-term survival with an area under the curve of 0.816.
