Dataset Information

Timing of Impella implantation and outcomes in cardiogenic shock or high-risk percutaneous coronary revascularization.

ABSTRACT:

Objective

To evaluate the role of the microaxial percutaneous mechanical circulatory support device (Impella® pump) implantation pre-percutaneous coronary intervention (PCI) versus during/after PCI in cardiogenic shock (CS) and high-risk PCI populations.

Background

A better understanding of the safety and effectiveness of the Impella and the role of timing of this support initiation in specific clinical settings is of utmost clinical relevance.

Methods

A total of 365 patients treated with Impella 2.5/CP in the 17 centers of the IMP-IT Registry were included. Through propensity-score weighting (PSW) analysis, 1-year clinical outcomes were assessed separately in CS and HR-PCI patients, stratified by timing of Impella support.
