Background Several studies addressed outcomes in terms of NACE and MACE in patients undergoing transradial vs tranfemoral cardiac catheterization. However, data on core quality measures such as length of stay and rehospitalization rates is lacking in the congestive heart failure population.

Method A retrospective chart analysis of 9,320 patients who were admitted to the hospital for chest pain and underwent cardiac catheterization. Based on ICD-9 codes, we included only patients with Congestive Heart Failure (CHF) with an Ejection Fracture ≤40 (HFrEF). We compared readmission rate and Length of stay in patients who underwent Transradial cardiac catheterization vs Transfemoral cardiac catheterization.

Results Of a total 9,320 patients undergoing diagnostic coronary angiography, 800 patients had HFrEF. Four hundred patients underwent Transradial cardiac catheterization and 400 patients underwent Transfemoral cardiac catheterization. In the transfemoral cardiac catheterization group, 37 (9%) were readmitted within 30 days of discharge while 17 (4%) patients of 400 patients who underwent transradial cardiac catheterization were readmitted within 30 days of discharged (Odds ratio: 2.3, 95% CI: 1.8–3, p value 0.005).

Length of stay was ∼5.2 days in transradial catheterization vs. ∼6 days in Transfemoral catheterization group (p 0.4).

Conclusion In our study population, transradial cardiac catheterization in HFrEF patients seemed to have a better outcome when compared to transfemoral cardiac catheterization in terms of 30-days readmission rate. Length of hospital stay was higher in the transfemoral group but did not achieve statistical significance, however. Larger studies that may also include patients with heart failure with preserved ejection fraction (HFpEF) are needed to investigate factors that may contribute to such outcomes.
