Study summary

The goal of this clinical trial is to learn whether two approaches to anesthesia and blood pressure management can improve care for adults having off-pump coronary artery bypass grafting (OPCAB). OPCAB is a type of heart bypass surgery performed without routinely using a heart-lung machine.

The main questions this study aims to answer are:

  • Does keeping mean arterial pressure (MAP), a measure of average blood pressure, at 65 mm Hg or higher during surgery lower the chance of major complications or death within 30 days after surgery compared with usual clinician-directed blood pressure management?
  • Does remimazolam provide more stable blood pressure and heart rate than propofol when used to maintain general anesthesia during surgery?

The researchers expect that targeted blood pressure management may lower the chance of major postoperative complications. They also expect that remimazolam may provide more stable blood pressure and heart rate than propofol.

Researchers plan to enroll 416 adults having elective OPCAB surgery. Participants will be randomly assigned to one of four groups. Each group will receive one of two blood pressure strategies and one of two medicines for maintaining general anesthesia.

Participants will:

  • Receive either targeted blood pressure management or usual clinician-directed blood pressure management during surgery.
  • Receive either remimazolam or propofol to maintain general anesthesia after the same standard anesthesia induction.
  • Have routine monitoring during surgery and assessments during recovery after surgery.
  • Complete follow-up assessments after surgery, including assessments of complications, recovery, and longer-term health. Some participants will also provide blood samples for a biomarker substudy.

The study will also explore whether the effect of the blood pressure strategy differs depending on which anesthetic medicine is used.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Interventions

  • OtherTargeted Blood Pressure Management

    Mean arterial pressure (MAP) will be maintained at 65 mm Hg or higher from induction of anesthesia until completion of surgery. A confirmed MAP below 65 mm Hg will prompt verification of the arterial pressure measurement and treatment directed at the presumed clinical cause. Treatment may include fluids, blood products, vasopressors, inotropes, heart-rate or rhythm management, cardiac repositioning, temporary pacing, or mechanical circulatory support when clinically indicated.

  • OtherLiberal Blood Pressure Management

    No trial-mandated mean arterial pressure target or study-defined treatment threshold will be imposed. Blood pressure will be managed at the discretion of the attending anesthesiologist according to usual clinical practice, the participant's clinical condition, and surgical conditions. Rescue treatment will be unrestricted when required for participant safety.

  • Remimazolam will be administered by continuous intravenous infusion for maintenance of general anesthesia beginning immediately after internal jugular vein catheterization. The initial infusion rate will be 1.0 mg/kg/hour and may be titrated within 0.5-1.5 mg/kg/hour according to clinical requirements. The infusion will be discontinued at completion of skin closure.

  • Propofol will be administered by continuous intravenous infusion for maintenance of general anesthesia beginning immediately after internal jugular vein catheterization. The initial infusion rate will be 1.0 mg/kg/hour and may be titrated within 0.5-1.5 mg/kg/hour according to clinical requirements. The infusion will be discontinued at completion of skin closure.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Oct 2026; primary completion for Dec 2027, 14 months later.

Of 753 non-industry interventional studies with no phase under Coronary Artery Disease, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 53. This study's planned 14 months is below that.

Counting every sponsor, half of 930 studies reached it within 30 months; a quarter within 15 and three quarters within 50.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 26, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
