Correlates of Hemodynamic Instability During Non-Emergent Percutaneous Coronary Intervention: Refining High-Risk Criteria for Utilizing Mechanical Circulatory Support.

Background: Previous studies using high-risk criteria to select patients for mechanical circulatory support (MCS) during percutaneous coronary intervention (PCI) have not consistently shown a benefit in reducing adverse outcomes. Identifying correlates for intra-procedural hemodynamic instability (HI) may improve patient selection for MCS.

Methods: Consecutive, hemodynamically stable patients undergoing non-emergent PCI between 2018 and 2022 were reviewed.
