HPI (Hypotension Prediction Index) Care Trial

June 20, 2025 updated by: Edwards Lifesciences

A Randomized Trial of the Hypotension Prediction Index in the Cardiac Operating Room and the Intensive Care Unit

A prospective single-center randomized controlled trial to determine if guided hemodynamic management with the Acumen HPI technology in the OR and ICU can reduce the mean duration of hypotension in cardiac surgery patients requiring cardiopulmonary bypass.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
350

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Subjects who are at least 18 years of age
  2. Subjects who have signed the Informed Consent Form
  3. Subjects with planned pressure monitoring with an arterial line
  4. Subjects with planned sternotomy
  5. Subjects with planned general anesthesia
  6. Subjects who have ASA Physical Status ≤ 4
  7. Subjects with planned cerebral oximetry monitoring
  8. Subjects with planned overnight hospitalization
  9. Subjects with planned cardiopulmonary bypass (CPB) "on-pump" surgery

Exclusion Criteria:

  2. Subjects with contraindications for Arterial Line Placement;
  3. Subjects participating in another (interventional) study
  4. Subjects in whom an intraoperative MAP target will be < 65 mmHg
  5. Subjects with pre-op or pre-pump or post-pump LVEF < 15%
  6. Subjects requiring heart transplant
  7. Subjects with pre-existing circulatory support devices or planned circulatory support devices post-bypass
  8. Subjects requiring emergency surgery
  9. Subjects with known or identified severe PAH (defined as pulmonary systolic pressure> 70mmHg or mean pressures > 55mmHg) as determined by a pre-operative echo or intraoperative Swan-Ganz
  10. Subjects with cardiovascular instability in the operating room necessitating the need to go back on bypass for a subsequent run

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: HPI Arm
AcumenTM HPI Software Feature to guide hemodynamic management in cardiac surgery post-CPB
Device: AcumenTM HPI Software Feature
The AcumenTM HPI Feature Software provides the clinician with physiological insight into a patient's likelihood of trending toward a hypotensive event. The AcumenTM HPI Feature Software suite is enabled by the minimally invasive Acumen IQ sensor.
Placebo Comparator: Non-HPI Arm
Non-protocolized standard of care management per clinician and provider judgement.
Other: Non-protocolized Standard of Care
Non-protocolized standard of care to treat subjects

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Assessment if the use of the AcumenTM HPI Feature Software reduces the mean duration of hypotension (defined as MAP < 65mmHg)
Time Frame: From post-bypass period to the first 8-hour ICU period
Assessment if the use of the AcumenTM HPI Feature Software reduces the mean duration of hypotension (defined as MAP < 65mmHg)
From post-bypass period to the first 8-hour ICU period

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 28, 2022

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
