Key result
Sustained ventricular tachycardia occurred in 4.3% of heart failure patients with CRT-P and was associated with a high risk of sudden cardiac death and lower 12-month overall survival (P<0.0001).
Why the study?
What is the incidence and prognostic significance of sustained ventricular tachycardia in chronic heart failure patients implanted with CRT-P?
Cohort (n=198)
Yes
What is the incidence and prognostic significance of sustained ventricular tachycardia in chronic heart failure patients implanted with CRT-P?
p-value: p=<0.0001
Sustained VT in the first year after CRT-P implantation is relatively rare (4.3%) but strongly associated with short-term adverse outcomes, particularly sudden cardiac death, highlighting the potential value of remote monitoring.
No takes yet. Share an insight, caveat, or question.
Sustained VT may mark high short-term SCD risk after CRT-P; leaves open whether remote monitoring improves outcomes in this observational cohort.
Bovéda et al. (2009) conducted a cohort in moderate or severe chronic heart failure (n=198). Sustained ventricular tachycardia (VT) vs. No sustained VT was evaluated on Incidence of sustained ventricular tachycardia (VT) (95% CI 1.1-7.5, p=<0.0001). Sustained ventricular tachycardia occurred in 4.3% of heart failure patients with CRT-P and was associated with a high risk of sudden cardiac death and lower 12-month overall survival (P<0.0001).
