Effect of Invasive Hemodynamic Monitoring on the Outcomes of Cardiogenic Shock in Patients With Acute Myocardial...

Area of Science:

• Cardiology
• Critical Care Medicine
• Clinical Hemodynamics

Background:

• The benefit of invasive hemodynamic monitoring in acute myocardial infarction with cardiogenic shock (AMI-CS) remains debated.
• Current guidelines lack definitive recommendations on optimal hemodynamic monitoring strategies for AMI-CS patients.

Purpose of the Study:

• To investigate the impact of invasive hemodynamic monitoring on in-hospital mortality in patients with AMI-CS.
• To compare outcomes between patients with AMI-CS who received invasive versus non-invasive hemodynamic monitoring.

Main Methods:

• Analysis of 1513 patients with AMI-CS from 2020-2022, comparing outcomes based on invasive monitoring use.
• Utilized propensity score matching to create comparable groups (488 pairs).
• Assessed in-hospital mortality, mechanical support escalation, and hospital length of stay.

Main Results:

• No significant difference in mortality was observed between invasive and routine monitoring groups (49.0% vs 49.18%, P > .99).
• Patients with invasive monitoring had longer hospital stays (7 vs 6 days, P = .016) and were more likely to require advanced interventions.
• Specific hemodynamic parameters (cardiac index, PAWCP, RAP) and Swan-Ganz catheter use did not predict mortality in the invasive monitoring group.

Conclusions:

• Invasive hemodynamic monitoring is not associated with improved in-hospital mortality in AMI-CS patients compared to routine monitoring.
• Findings underscore inconsistent evidence regarding hemodynamic monitoring methods in AMI-CS.
• Further research is necessary to guide clinical decision-making for optimal patient management.
