Effect of pulmonary artery catheter, type & combination of vasoactives for optimizing lactate clearance in acute myocardial infarction complicated by cardiogenic shock

J Crit CarePublished Observational cohort study

Authors' conclusion

The right combination of vasoactive medications and the probable use of a PAC could significantly impact the achievement of complete LC in <96 h.

Study context

Population
Patients with AMI complicated by cardiogenic shock (AMI-CS)
Participants
651 patients
Exposure
Pulmonary artery catheter (PAC) presence and vasoactive drug type/combination in relation to lactate clearance
Outcome
Lactate clearance time (complete LC: serum lactate <2 mmol/L)
Methodological detailsCART analysis
  • CART analysis

Main finding

As reported in the abstract

Lactate clearance time

PAC presence correlated with faster lactate clearance (LC)

−17.54 h

Levosimendan associated with lower lactate levels and faster LC

−8.82 h

Dobutamine associated with lower lactate levels and faster LC

−8.77 h

Vasopressin linked to slower LC

9.16 h

Observational data: associations, not effects.

Further findings

Mortality, slow LC (>96 h)

Slow LC (>96 h) associated with increased mortality

Mortality by vasoactive combination (CART)

Lowest-mortality combination had higher complete LC and a trend for higher %LC
