Preoperative Maltodextrin for Heart Failure
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether a maltodextrin solution (a type of carbohydrate drink) can improve heart function in individuals undergoing coronary artery bypass surgery, particularly those with reduced left ventricular ejection fraction (a condition where the heart doesn't pump blood effectively). Participants will receive either the maltodextrin drink or a placebo (a harmless substance with no active treatment) before surgery. This study may suit individuals scheduled for early morning heart bypass surgery who have been informed that their heart's pumping ability is less than optimal. As a Phase 4 trial, this research aims to understand how the already FDA-approved treatment benefits a broader range of patients.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What is the safety track record for the Maltodextrin solution?
Research has shown that maltodextrin is generally safe for people. Studies found that patients who drank a maltodextrin solution before surgery felt less hungry, thirsty, and tired, indicating the solution is usually well-tolerated. Another study demonstrated that taking maltodextrin before heart surgery improved recovery, with patients needing fewer medications and spending less time in the hospital. Although these studies did not identify any serious side effects, discussing your specific situation with your doctor before joining a trial is always important.12345
Why are researchers enthusiastic about this study treatment?
Unlike standard heart failure treatments like beta-blockers and ACE inhibitors, which primarily manage symptoms and improve heart function over time, the maltodextrin solution is being explored for its potential as a preoperative booster for heart surgery patients. This solution is unique because it provides a quick energy source, potentially improving the body's resilience to the stress of surgery. Researchers are excited about this approach because it might enhance recovery and outcomes in heart failure patients undergoing surgery, offering a novel pre-surgery nutritional strategy that could work alongside existing treatments.
What evidence suggests that Maltodextrin solution might be an effective treatment for heart failure?
Research has shown that Maltodextrin, a type of carbohydrate, might help improve heart function during surgery. Previous studies found that taking Maltodextrin before surgery can reduce hunger, thirst, and tiredness in patients. This suggests it might make patients more comfortable and possibly aid in their recovery. In this trial, participants in the intervention group will receive Maltodextrin to evaluate its effects. While direct evidence that Maltodextrin improves heart function during heart surgery is not yet available, its ability to ease pre-surgery discomfort is promising. Researchers are actively studying its potential benefits for heart surgery patients to gain clearer insights.23467

Are You a Good Fit for This Trial?
This trial is for adults over 18 who are scheduled for coronary artery bypass grafting surgery and have a left ventricular ejection fraction below 50%. It's specifically for surgeries starting at 7:30 am. People with swallowing difficulties, slow stomach emptying, intolerance to oral intake, celiac disease, or type 1 diabetes cannot participate.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening

What Are the Treatments Tested in This Trial?
Interventions
- Maltodextrin solution
- Placebo solution
- Water solution
Trial Overview
The study is testing if drinking a Maltodextrin solution before heart surgery can help maintain cardiac function better than a placebo. Patients are randomly assigned to one of the two groups without knowing which one they're in (double-blinded).
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Placebo Group
Patients in the intervention group will receive an oral preparation of 50 grams of Maltodextrin solution mixed in 400 millilitres (mL) of water twice the night before surgery and within 2-3 hours before surgery. The entire drink is meant to be consumed within 15 minutes.
Patients in the intervention group will receive a placebo in 400 millilitres (mL) of water twice the night before surgery and within 2-3 hours before surgery. The entire drink is meant to be consumed within 15 minutes.
