Viles-Gonzalez JF, et al. - Given that ventricular arrhythmias (VA) create a huge mortality burden, researchers analyzed the clinical outcomes of VA, including ventricular tachycardia (VT), implantable cardiac defibrillator (ICD) shocks, and sudden cardiac death (SCD), to assess factors that predict morbidity and mortality, patterns of ICD and VT ablation usage, and how these metrics impact overall healthcare utilization. In SCD patients, a decrease in admissions for VA, a decrease in ICD utilization, a change in pattern of VT ablation utilization, and an increase of in-hospital mortality were observed. In-hospital mortality was most strongly predicted by admission for SCD, followed by patients with non-ischemic heart disease, patients with ICD shocks, and all patients with a Charlson Comorbidity Index ≥ 2. This should be considered when developing risk models for patients undergoing risk-assessment of SCD.
