Clinical outcomes between RR-NSVT (-) and RR-NSVT (+) patients
Table 3 shows the clinical outcomes in both groups. A higher incidence
of VTAs (11.8% vs. 67.6%; p<0.001), electrical storm (1.5%
vs. 14.7%, p=0.009), and admission for HF (33.8% vs. 52.9%; p=0.037)
were noted in the RR-NSVT (+) group compared to the RR-NSVT (-) group.
The incidence of cardiovascular and all-cause mortality did not show a
significant difference between groups. A longer follow-up period was
noted in the RR-NSVT (+) group.
A Kaplan-Meier curve on the occurrence of VTAs showed a significant
difference between the groups (log-rank p<0.001) (Figure 2A),
which was consistent in patients with primary (Figure 2B) and secondary
prevention (Figure 2C). No significant differences in the event-free
survival of HF admission (Figure 3A) and cardiovascular mortality
(Figure 3B) were observed between groups.
