Heart Attack Blood Oxygen Therapy Trial

'Heart attack', known as acute ST-segment elevation myocardial infarction, is a leading cause of heart failure and death. A lack of blood and oxygen damages the heart muscle potentially causing heart failure and premature death. During the past 25 years, despite intensive research efforts, few, if any new medicines have been shown to prevent heart failure after a heart attack. New treatment approaches are needed. The standard treatment for a heart attack is for a doctor to reopen the blocked blood vessel. The treatment is called primary percutaneous coronary intervention, or 'primary PCI'. The doctor places a thin plastic tube in a blood vessel in the wrist. The doctor then passes a longer thin tube via the wrist into the blocked heart artery. A small balloon is then used to open the blockage and a thin metal tube (stent) is placed inside the blood vessel to keep it open. The patient then returns to the ward. Supersaturated oxygen therapy is designed to increase the blood oxygen level after the stent has been placed. The treatment lasts for one hour. The treatment is approved (CE-mark, FDA-approved) for patients presenting to doctors within 6 hours of symptoms onset. Supersaturated oxygen therapy is supported by results from two prior studies (AMIHOT, AMIHOT-II). Previously, the approach involved passing the plastic tubes via the femoral artery in the groin, limiting adoption. Since using the wrist is now standard care approach for heart attack treatment, our idea is to gi…
