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

N/A

Recruiting

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

Must not have

Various cardiovascular and medical conditions (e.g., iliofemoral artery diameter <5 mm, severe bilateral peripheral vascular disease, ventricular arrhythmias, aortic stenosis, prior mechanical valve or self-expanding TAVR, prior CABG within three months, severe pulmonary hypertension, severe RV dysfunction, severe tricuspid insufficiency, platelet count <75,000 cells/mm3, on dialysis, prior stroke within the previous three months, chronic oral anticoagulant use, plan for surgery within 6 months necessitating discontinuing antiplatelet agents)

STEMI ≤24 hours from the onset of ischemic symptoms or at any time if mechanical complications of transmural infarction are present

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.
