Oxygen therapy for patients suffering from a heart attack does not prevent heart failure

(Karolinska Institutet) Oxygen therapy does not prevent the development of heart failure. Neither does it reduce the long-term risk of dying for patients with suspected heart attack. This has been proven for the first time by researchers at Karolinska Institutet as a result of a major Swedish study. The study is to be presented at the European Society of Cardiology's (ESC) cardiology congress in Munich and published at the same time in the journal Circulation.
