Implication
Sub-analysis shows link between risk factors and outcomes in patients with ICD and CRT-D, suggesting careful monitoring is essential.
Key Points
- No significant difference in ventricular tachyarrhythmia rates was observed between higher-risk and lower-risk groups for either device cohort, indicating consistent outcomes.
- In the ICD cohort, higher-risk patients had a 2.24 times greater risk of heart failure hospitalization compared to lower-risk patients over 24 months.
- Median lengths of heart failure hospital stays were longer for higher-risk patients, underscoring the need for targeted interventions.
- The study suggests ICD implantation remains critical for patients at risk of sudden cardiac death, regardless of risk factor count.
