Brief Summary:
This study will evaluate the benefit of Intralipid® or placebo administered prior to reperfusion to limit ischemia reperfusion injury as measured by the geometric mean difference of the release of troponin I over 72 hours after coronary artery bypass.

Condition or disease Intervention/treatment Phase
Reperfusion Injury Drug: Intralipid 20% Drug: Modified Ringers Lactate Phase 2 Phase 3

Detailed Description:

A single center randomised control study on cardiac protection with INTRALIPD in patients undergoing coronary artery bypass grafting on cardiopulmonary bypass.

Purpose and objectives:

Reperfusion after coronary artery bypass grafting is associated with a modifiable leak in cardiac Troponin I (cTnI) secondary to ischemia reperfusion injury. The purpose of the study is to test whether INTRALIPID administered at reperfusion can limit myocardial reperfusion injury as measured by cTnI release in patients undergoing coronary artery bypass grafting.

Trial design:

This study is a prospective single centre double blind placebo controlled randomised trial.

Sample size: 30 Adult Male and Female Patients

Investigational drug(s):

INTRALIPID 20% Fresenius Kabi (SA) Registration Number: K/25.2/316 Formulation: IV Solution Strength: 20% (200mg/ml) Modified Ringer's Lactate Fresenius Kabi (SA) Registration Number: C/24/218 Formulation: IV Solution Dose for both drugs: 1.5 ml/kg Administration: IV Bolus through CVP Blood sampling and tissue biopsies: cTnI will be sampled at fixed time points, baseline 1, 6, 9, 12, 24, 48, and 72 hours after surgery. The first biopsy will be done prior to cardioplegic arrest and the second biopsy will be done 5 minutes after reperfusion.

Safety assessments:

The safety of the interventions will be monitored routinely for all patients and these will focus on:

  1. Changes in the lipid profile after Intralipid
  2. Coagulation as measured by ACT, TEG and PFA
  3. Oxygenation with Arterial Blood Gas monitoring
  4. Hemodynamic monitoring and echocardiography
  5. Lipid interference with laboratory measurements. The laboratory will be informed on specimen preparation to avoid interference with instruments
  6. Post operative hemodynamic Intensive Care Unit Monitoring Measurement will be reported on all safety monitoring and will be considered adverse events where the measured parameter results are out of range from the laboratory references.

Efficacy assessments. Primary endpoint: The efficacy of the drug will be determined by the geometric mean (95% CI) difference in the AUC of the cTnI concentration calculated according to the trapezoid rule.

Secondary End Point: Exploring the molecular mechanism involved in cardiac protection by analyzing tissue sample differences in the phosphorylation cytoplasmic protein kinase.

Arm Intervention/treatment
Active Comparator: Intralipid 20%
Intravenous single bolus of 1.5 ml/kg of Intralipid 20% over 3 minutes.
Drug: Intralipid 20%
Single intravenous bolus dose of 1.5 ml/kg over 3 minutes
Other Name: Lipid Emulsion 20%

Placebo Comparator: Modified Ringers Lactate
Intravenous single bolus of 1.5 ml/kg of MRL over 3 minutes.
Drug: Modified Ringers Lactate
Single intravenous bolus dose of 1.5 ml/kg over 3 minutes
Other Name: MRL

Primary Outcome Measures :
  1. Comparison of the serum Troponin I Leak over 72 hours [ Time Frame: Over 72 hours ]
    The primary endpoint will be assessed by the geometric mean (95% CI) difference between the protocol and control groups of the area under the curve for the cTnI concentration in serum over 72 hours (sampled at 1, 6, 12, 24, 48 and 72 hours) calculated according to the trapezoid rule.

Secondary Outcome Measures :
  1. Signaling Pathways of intralipid induced cardiac protection [ Time Frame: 5 minutes after reperfusion ]
    Two right atrial and two left ventricular biopsies will be collected before cardioplegia and the second will be collected 5 minutes prior to reperfusion. These will be used to compare the activation of signalling protein between the groups.
