Background: In patients with congestive heart failure (CHF), right heart catheterization (RHC) is recommended in certain situations. However, there remains uncertainty of its impact on mortality and other clinical outcomes.
Methods: A secondary analysis of the United States National Inpatient Sample (NIS) database from 2008-2012 was conducted. All patients aged 18 years and older with the primary discharge diagnosis of CHF were included. Cohort was divided based on RHC use. Also, number of days from admission to the first RHC in each hospitalization was recorded.
Results: In the overall cohort, there was an increase in the observed mortality in those who underwent RHC (8.9% vs. 3.1%, P<0.001). However, in those with cardiogenic shock, RHC use was associated with lower in-hospital mortality (21% vs. 28.1%, P<0.001).
Interestingly, patients who underwent RHC in the first seven days of hospitalization had a significantly lower mortality than those who had RHC later in their hospitalization course (7.6% vs. 14.4%, P<0.001) Fig-1.
Conclusions: Overall mortality was higher with RHC use and likely reflects greater likelihood of invasive hemodynamic monitoring in sicker individuals. However, the mortality was actually better when it was used in those with cardiogenic shock and earlier during hospitalization. This finding indicates that timely use of PA catheterization in tenuous hemodynamic conditions has a favorable effect.
