Background

Pulmonary artery catheterization (pulmonary artery catheterization) has re-emerged as a hemodynamic phenotyping tool in heart failure-related cardiogenic shock (HF-CS).

Methods

Using the National Inpatient Sample (2016-2022), we identified adult hospitalizations with cardiogenic shock excluding acute coronary syndrome.

n = 3496

Results

Pulmonary artery catheterization use linked to lower risk of dying in hospital

AOR by subgroup · 95% CI

More results

Among 17,480 weighted hospitalizations (unweighted n = 3496), 2655 (15.2%) underwent pulmonary artery catheterization.

Utilization more than doubled from 9.9% in 2016 to 21.3% in 2022 (P for trend <0.001).

More results

The mortality association persisted across all four sensitivity analyses, including after excluding durable left ventricular assist device/transplant patients (SA4: aOR 0.74; 95% CI 0.59-0.92; P = 0.008), with aORs ranging from 0.58 to 0.74 (all P ≤ 0.010).

Conclusion

Pulmonary artery catheterization use in HF-CS more than doubled from 2016 to 2022, remained concentrated at large urban teaching hospitals, and was independently associated with lower in-hospital mortality across four sensitivity analyses, including after excluding left ventricular assist device/transplant patients, supporting prospective evaluation of pulmonary artery catheterization-guided management in HF-CS.
