Key result
Elevated SII is linked to electrical storm and predicts mid-term mortality.
Why the study?
It is not known whether readily available clinical markers can detect subclinical inflammation that may contribute to acute arrhythmogenesis in patients undergoing VT ablation.
Does the systemic immune-inflammatory index predict mid-term mortality in patients undergoing ventricular tachycardia ablation?
Observational
Does the systemic immune-inflammatory index predict mid-term mortality in patients undergoing ventricular tachycardia ablation?
p-value: p== 0.003
The systemic immune-inflammatory index (SII) is elevated in patients with electrical storm and serves as a predictor of mid-term mortality following VT ablation.
May refine post-VT ablation risk stratification; leaves open prospective validation before clinical use.
BACKGROUND: Ventricular arrhythmias (VA) are a major cause of sudden cardiac death (SCD) in heart failure patients. It is not known whether readily available clinical markers are of any clinical yield in detecting a subclinical inflammation that may be inflicted in acute arrhythmogenesis. AIMS: This study aimed to evaluate the prognostic value of inflammatory markers in patients undergoing ventricular tachycardia (VT) catheter ablation and to compare characteristics between those with electrical storm (ES) and elective ablation (EL). METHODS: < 0.05 was considered significant in all analyses. RESULTS: = 0.003), respectively. CONCLUSION: SII is notably higher in those experiencing ES and is a predictor of mid-term mortality.

Baskovski et al. (2025) conducted an observational in Ventricular tachycardia. Systemic immune-inflammatory index (SII) vs. Elective ablation (EL) was evaluated on Mid-term mortality (p== 0.003). Systemic immune-inflammatory index (SII) is notably higher in patients experiencing electrical storm and is a predictor of mid-term mortality (P=0.003).
