A new study from Karolinska Institutet shows that 1 in 5 patients admitted for acute myocardial infarction are infected with Helicobacter pylori and that it is possible to introduce screening for this bacterium in routine care. The results are published in the American Heart Journal. The researchers are now planning a large randomised trial to find out whether screening and treatment of the infection reduces the risk of stomach bleeding and improves cardiovascular outcomes in this patient group.
