Kaplan-Meier analysis revealed significantly higher VT recurrence across the <25% cohort when compared with patients with an LVEF ≥50% (hazard ratio [HR] 2.27, 95% CI 1.46 to 3.54, P < .001); however, the 25% to 49% group did not reach statistical significance (HR 1.41, 95% CI 1.00 to 1.99, P = .051) ( Figure 1 ).
