Impella-Supported PCI for Coronary Heart Disease (PROTECT IV Trial)

Research Sponsored by Abiomed Inc.
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
OR B. Subject has STEMI ≥24 hours and <30 days after symptom onset with an LVEF ≤30% NOTE: In patients qualifying with recent STEMI, the LVEF must be demonstrated to be ≤30% by quantitative echocardiography after the primary PCI procedure (if performed) and within 72-hours prior to the planned randomization. If primary PCI was not performed, the qualifying echocardiogram will be the one taken during the index hospitalization closest to the index procedure. If the site read is qualitative only (i.e., only provides broad ranges without detailed LVEF quantification), the Echo Core Lab must confirm the LVEF is ≤30% before subject enrollment.
Age ≥18 years and ≤90 years
Screening 3 weeks
Treatment Varies
Follow Up 3 years

PROTECT IV Trial Summary

This trial will test if using a heart pump called Impella during high-risk heart procedures helps improve symptoms, heart function, and health better than the current standard of care.

Who is the study for?
Adults aged 18-90 with complex coronary artery disease, reduced left ventricular function (LVEF ≤40% or ≤30% in specific cases), and planned high-risk PCI. Candidates must not have life-threatening non-cardiac conditions, recent severe heart attacks, cardiogenic shock, pregnancy, or other serious medical issues that could affect participation.Check my eligibility
What is being tested?
The trial is testing whether using the Impella® devices during high-risk percutaneous coronary intervention (PCI) improves symptoms and heart function compared to standard care with an intra-aortic balloon pump in patients with significant heart vessel blockage and weakened heart pumping ability.See study design
What are the potential side effects?
Potential side effects of using Impella® devices may include bleeding at the catheter insertion site, blood vessel damage, irregular heartbeat, blood clots leading to stroke or other problems; however individual experiences can vary.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures

Secondary outcome measures
Achievement of complete anatomic revascularization after the index and planned staged procedures
All CV hospitalizations through 3 years
