This cohort study evaluates 3-year mortality and hospitalization in octogenarians with HFrEF, suggesting CRT-D may reduce hospital visits without improving survival.
Key Points
Three-year mortality rates were similar between CRT-D and CRT-P in octogenarians (37.2% vs 39.1%).
CRT-D recipients had significantly fewer hospitalizations compared to CRT-P recipients (mean 4.05 vs 5.36; p = 0.032).
Subgroup analysis revealed modestly lower mortality for CRT-D in patients with EF ≤25% and 26-35%, though not statistically significant.
Female patients receiving CRT-D exhibited lower mortality rates than their male counterparts (20.0% vs 29.5%; HR 0.637).
