High Pressure Linked to Mortality During ECMO Support
For patients on VA ECMO, pulmonary artery pressure readings at 24 hours could indicate an increased risk of in-hospital death.
Updated on Oct. 13, 2026 in Heart Disease
A retrospective study published October 5, 2026, found that patients on veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) with a pulmonary artery diastolic pressure above 18 mm Hg faced a 29% higher risk of in-hospital mortality. The findings reflect outcomes for patients receiving treatment for cardiogenic shock between 2015 and 2020.
Why it matters
These results provide clinicians with a clearer hemodynamic target during VA ECMO support, potentially refining how doctors monitor and stabilize patients in cardiogenic shock. The study highlights that conventional monitoring techniques may not always correlate with improved patient survival outcomes.
This retrospective study analyzed 2,711 adult patients out of a total cohort of 7,654 who received VA ECMO for cardiogenic shock. Researchers measured pulmonary artery diastolic pressure at 24 hours to compare in-hospital mortality rates within a 30-day window.

University of Utah Health
An academic medical center that led the research on hemodynamic targets for patients receiving circulatory support.
The details
VA ECMO is a temporary life-support system that pumps oxygenated blood throughout the body for patients experiencing severe cardiogenic shock. During this process, the heart requires precise hemodynamic balance to function effectively alongside the machine. Elevated pulmonary artery diastolic pressure suggests the heart is struggling against high resistance, which researchers found correlates with poorer outcomes in this critically ill population.

Health Landscape
This research follows a pattern of refining hemodynamic targets within the University of Utah Health ECMO study program to better manage complex cardiogenic shock. It signals a shift toward more precise monitoring standards as providers move beyond simple support to optimize survival outcomes for ECMO recipients.
If you or a loved one is undergoing VA ECMO support, these findings emphasize the critical importance of hemodynamic monitoring in the intensive care unit. Conversations with a doctor regarding the specific pressure goals and monitoring strategies being used are essential for understanding the management of care during treatment.
The takeaway
High pulmonary artery pressure during early VA ECMO support may signal an increased risk of mortality for patients with cardiogenic shock. If a loved one is in the ICU on circulatory support, ask the medical team about the specific hemodynamic targets being monitored to ensure stabilization.
