Scientists at the Karolinska Institute conducted the most significant Swedish study on the real benefits of the oxygen therapy. Accordingly, the oxygen therapy doesn’t prevent heart failure in heart attack patients. The study, which will be presented at the European Society of Cardiology’s (ESC) cardiology congress in Munich, Germany, and published in the journal Circulation, could imply a significant impact on the healthcare recommendations for heart attack patients.
For more than one hundred years, oxygen has been employed as a treatment method for patients suffering a heart attack, even though such therapy presented little or no beneficial effects on those individuals with normal oxygen levels in the body. Since the 2000s, the scientists and cardiology experts from all over the world, have started questioning the real effects of this kind of therapy. However, not many scientific studies have been conducted in this directions, and this is why this new research from the Karolinska Institute might change the game for healthcare recommendations for heart attack patients.
Oxygen therapy is not preventing heart failure in patients suffering from a heart attack
“Our new study has filled a central gap in knowledge regarding how to treat patients suffering a heart attack. One year ago, we were able to confirm that oxygen therapy does not appear to reduce the risk of dying up to one year after the heart attack,” explained Robin Hofmann, the senior cardiologist and researcher at the Department of clinical science and education, Södersjukhuset, of the Karolinska Institute.
“We can now substantiate these findings for a long-term perspective and show that oxygen therapy does not reduce the development of heart failure, the most worrying complication of heart attacks,” he added.
The research, carried out in 32 Swedish hospitals, implied random treatment, either involving oxygen or not, on about 6,700 heart attack patients. According to the study, low doses of oxygen therapy are not harmful but do not enhance the survival rates of the patients.
In conclusion, oxygen therapy doesn’t prevent heart failure in heart attacks patients, according to this new study conducted by the Karolinska Institute, in Sweden.
