Kaplan–Meier estimates for event‐free survival in CRT‐D recipients for primary prevention of sudden cardiac death with and without prior history of NSVT. Outcome events were death from any cause (A), heart failure death (B), sudden cardiac death (C), and noncardiac death (D). The mean follow‐up period was 22 ± 12 months in the NSVT group and 19 ± 11 months in the No NSVT group (P = .078). A, The rate of death from any cause at 12 and 24 months was 12.8% and 19.8% in the NSVT group, and 7.1% and 12.1% in the No NSVT group (NSVT vs No NSVT, P = .074 by log‐rank test). B, The rate of heart failure death at 12 and 24 months was 5.2% and 9.8% in the NSVT group, and 2.8% and 2.8% in the No NSVT group (NSVT vs No NSVT, P = .030 by log‐rank test). C, The rate of sudden cardiac death at 12 and 24 months was 3.1% and 3.9% in the NSVT group, and 1.2% and 3.0% in the No NSVT group (NSVT vs No NSVT, P = .655 by log‐rank test). D, The rate of noncardiac death at 12 and 24 months was 4.4% and 7.5% in the NSVT group, and 3.3% and 6.8% in the No NSVT group (NSVT vs No NSVT, P = .829 by log‐rank test)
