Some exciting studies have emerged showing how D-ribose affects active human heart tissue and its function.14,15 Investigators have shown how increased ATP levels translate into improved heart muscle function, better blood flow, and quicker recovery with protection from the ravages of reperfusion-induced oxidation.Ischemic (no blood flow) events such as a heart attack cause areas of the heart muscle to “hibernate” exactly as if they were awaiting a higher-energy environment to return to their normal rates of activity.

University studied this phenomenon in a group of patients with coronary artery disease, subjecting them to a “thallium stress test.”16 In this test, patients are injected with a radioactive tracer immediately following moderate exercise, and the distribution of the tracer is followed using special cameras. The patients received either D-ribose infusion or a placebo and the tests were repeated at four and 24 hours, respectively. The groups were then switched to receive the opposite preparation. The results were stunning—the images taken just four hours after D-ribose infusion revealed 21 areas of defective tissue that had not been seen in the placebo group, indicating that D-ribose was “waking up” viable areas of heart muscle and helping improve identification of viable ischemic heart muscle.16 A larger study published the same year showed similar results.17 These studies show that D-ribose not only enhances cardiologists’ ability to accurately gauge the degree of heart damage, but also suggest strongly that this supplement might hasten the recovery of healthy heart function following a heart attack.
