Read our Coronary Artery Disease research guide →Researchers are testing a new type of MRI scan called hyperpolarized 13C MRI to measure how your heart muscle is using energy. This scan might help doctors see which parts of your heart can recover after bypass surgery and predict how well you'll do afterward. The study compares heart patients before and after surgery with healthy volunteers to understand what normal heart metabolism looks like.
Right now, doctors don't have a good way to predict which patients will benefit most from heart bypass surgery or how well their hearts will recover. This new imaging technique could help doctors understand your heart's metabolism (how it uses energy) and make better decisions about your treatment.

If you're a surgery patient, you'll have one MRI scan before your scheduled bypass surgery and another scan 4-6 months after surgery. During the scan, you'll receive an injection of a special substance (hyperpolarized pyruvate) that helps the MRI take detailed pictures of your heart's metabolism. The scan itself takes about an hour. Healthy volunteers will have one scan. Blood tests will also be done to measure cholesterol, triglycerides, and other markers.
