Background: Real time data on influence of cardiac devices in patients with heart failure with reduced ejection fraction(HFrEF) is limited.
Methods: We utilized National Readmission Data (NRD) 2013. HFrEF was identified using ICD 9 code (428.2x) as primary diagnosis. Considering modern cardiac devices including BiV ICD, ICD, permanent pacemaker work as both ICD and pacemaker, we club them together using appropriate ICD 9 procedural code as either primary or secondary procedural fields. Propensity score match (1:2), Hierarchical logistic and stratification method were used to adjust for confounders. Co primary outcomes were 30-day readmission and short term mortality(In hospital mortality + 30-day mortality).
Results: We included 109,479 patients with HFrEF in study cohort. 4.54 % of the patients (n=4972) received cardiac devices during primary admission and 19.13% of patients were readmitted. Hierarchical modeling showed that patients with cardiac devices had significantly reduced 30-day readmission rate (OR: 95% CI, P value) (0.69, 0.65-0.73, 0.001), in hospital mortality (0.40, 0.31-0.52, <0.001) and short term mortality (0.37, 0.24-0.56, <0.001). Results were similar even after adjusting with propensity score match method and stratifying in multiple high risk groups. (figure 1).
Conclusions: Our study found significant reduction in 30 -day readmission rates and short term mortality benefits in patients with HFrEF who received one of the modern cardiac devices during index admissions.
