Pulmonary Artery Catheter Use in Acute Myocardial Infarction-Cardiogenic Shock
Why the study?
Contemporary patterns of pulmonary artery catheter use and associated clinical outcomes in acute myocardial infarction-cardiogenic shock required evaluation.
Does pulmonary artery catheter use improve in-hospital mortality in patients with acute myocardial infarction-cardiogenic shock?
Population
364 001 admissions with AMI-CS from the National Inpatient Sample (2000-2014)
Comparison
PAC use vs no PAC use
Design
Retrospective cohort study

Implication
Declining PAC use in AMI-CS should not change monitoring decisions; leaves open the need for prospective trials on hemodynamic guidance.

P
Population
364,001 admissions with acute myocardial infarction-cardiogenic shock (AMI-CS) from the National Inpatient Sample (2000-2014). Exclusions: concomitant cardiac surgery or non-AMI aetiology for cardiogenic shock.
I
Intervention
Pulmonary artery catheter (PAC) use
C
Comparator
No pulmonary artery catheter (PAC) use
O
Outcome
In-hospital mortalityhard clinical
In patients with AMI-CS, PAC use declined significantly between 2000 and 2014 and was not associated with a difference in in-hospital mortality after propensity matching.
