  • ECG and/or biomarker evidence of ST-segment elevation myocardial infarction (STEMI), STEMI equivalents, or new or presumed new left bundle branch block or
  • ECG and/or biomarker evidence of non-ST-segment elevation myocardial infarction (NSTEMI) and angiographic evidence of one or more culprit vessels
  • Cardiogenic shock confirmed by at least two of the following:
  • Tissue hypoperfusion, manifested by an arterial or venous blood lactate level ≥2.5 mmol/L or SvO2 <55% in the presence of a PaO2 > 90mmHg

About this study

Official title: Observational Assessment of Support With Impella® Best Practices in Acute Myocardial Infarction Complicated by Cardiogenic Shock

The observational study titled "Observational Assessment of Support with Impella Best Practices in Acute Myocardial Infarction Complicated by Cardiogenic Shock (OASIS-AMICS)" aims to evaluate the safety outcomes of patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) who receive Impella CP during percutaneous coronary intervention (PCI) and who are managed with Impella best practices while receiving guideline-directed standard of care. This prospective, multicenter study will enroll up to 350 hemodynamically unstable patients with cardiogenic shock of less than 12 hours duration and acute myocardial infarction (AMI) of less than 24 hours duration. Cardiogenic shock will be confirmed by tissue hypoperfusion (lactate ≥ 2.5mmol/L and/or SvO2 <55% with a normal PaO2) and systolic blood pressure <100 mmHg and/or need for vasopressor therapy (dopamine/norepinepherine or epinephrine). Patients will be assessed for various safety endpoints, including a composite safety endpoint involving major bleeding, acute limb ischemia, and acute kidney injury. Secondary endpoints will evaluate all-cause mortality, major adverse cardiovascular and cerebrovascular events (MACCE), and hospitalizations through 1-year post-Impella implant. All patients presenting with AMICS at study sites will be screened for inclusion in the study after hospital discharge (or after death, if prior to hospital discharge). IRB approved consent waiver will be used to collect data from electronic health records from; Impella placement to discharge and post-discharge at 30 days post-Impella implant, 6 months post-Impella implant, and 1 year post-Impella implant.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 6 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Sameera Dasari, PhD (978-914-8882, sdasar12@its.jnj.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite Safety (time frame: All in-hospital events through discharge, an average of 15 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06964685, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jul 2026.
