Glutathione infusion before primary percutaneous coronary intervention: a randomised controlled pilot study

What Was Tested

This randomized controlled trial paper looks at Glutathione.

Glutathione (GSH) is a water-soluble tripeptide with a potent oxidant scavenging activity.

Who Took Part

The age groups tagged for this paper are older adults, both men and women.

How the Study Was Run

In design terms this was a randomized, double-blind, placebo-controlled and pilot study.

Because people in this Glutathione study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

As a double-blind Glutathione study, the assignments were hidden from both participants and investigators until the end.

A placebo (an inactive look-alike) gave the Glutathione group a baseline to be compared against.

It is described as a pilot, a small early test of whether a larger Glutathione study would be practical.

A time span of 5 days appears in the methods.

Peripheral blood samples were obtained before and at the end of the procedure, as well as after 5 days.

H2O2 production, 8-iso-prostaglandin F2α (PGF2α) formation, H2O2 breakdown activity (HBA) and nitric oxide (NO) bioavailability were determined.

Serum cardiactroponin T (cTpT) was measured at admission and up to 5 days.

What Was Measured

The subject headings attached to it are Biomarkers, Coronary Circulation, Glutathione, Oxidative Stress, Percutaneous Coronary Intervention, Pilot Projects and Preoperative Care.

The authors tagged it with the keywords STEMI, glutathione:, hydrogen peroxide, percutaneous coronary interventions, reactive oxygen species and reperfusion injury.
