Cardiogenic shock (CS) continues to have high mortality and the influence of pulmonary artery catheters (PAC) in CS patients on a nationwide scale is yet to be well elucidated. We aim to identify the trends and outcomes in CS patients managed with PAC. We conducted a retrospective analysis of the adults with CS using Healthcare Utilization Project Nationwide Inpatient Sample Database from 2009 through 2014 in the United States. A total of 104,455 patients were identified as having the diagnosis of CS during their index hospitalization. Trend analyses were performed using the Cochran-Armitage test of trend for categorical variables, and survey-specific for linear regression for continuous variables. Interestingly, the in-hospital mortality was lower in patients with PAC (29.7 vs 37.6%; p <0.001). Overall, patients with PAC had increased total hospital charges (292,144 vs 171,673 $; p <0.001) and length of stay (16.94 vs 10.78 days; p <0.001). Trends in use in patients requiring PACs were identified (Figure 1). Furthermore, we found a disparity on the use of PACs in CS in which females had less invasive hemodynamic monitoring than males (Figure 2). There has been an increase in the number of patients with CS from 2009 to 2014, and the use of PAC had decreased. PACs were used less in females than in males, although we saw a possible benefit of PACs with in-hospital mortality in CS (p <0.001).
