Right Heart Catheterization in Cardiogenic Shock Is Associated With Improved Outcomes: Insights From the Nationwide Readmissions Database.

Background The usefulness of right heart catherization (RHC) has long been debated, and thus, we aimed to study the real-world impact of the use of RHC in cardiogenic shock. Methods and Results In the Nationwide Readmissions Database using (), we identified 236 156 patient hospitalizations with cardiogenic shock between 2016 and 2017. We sought to evaluate the impact of RHC during index hospitalization on management strategies, complications, and outcomes as well as on 30-day readmission rate.
