BACKGROUND Previous studies have shown that there are gender-related differences in the assessment and treatment of myocardial infarction, despite international
guidelines that prescribe identical treatment for women and men. We investigated whether these differences occurred in Norway.
MATERIAL AND METHOD All patients admitted to Norwegian hospitals with myocardial infarction from 1 January 2013 to 31 December 2014 and registered in the
Norwegian Myocardial Infarction Registry were included. Data from the registry were used to analyse differences in the assessment, treatment, complications and survival
of women and men in different age groups.
RESULTS A total of 26 447 myocardial infarctions were registered in the Norwegian Myocardial Infarction Registry in the period 2013-2014. Fewer women than men were
assessed by means of coronary angiography. Percutaneous coronary intervention (PCI) was used to virtually the same extent for both genders if coronary stenosis was
found. Women were recommended secondary prophylactic medication to a lesser extent than men. There were no major differences between men and women in the
incidence of complications in the course following myocardial infarction or in survival.
INTERPRETATION Fewer women than men suffering acute myocardial infarction were assessed by means of coronary angiography, and women were recommended
secondary prophylactic medication less often than men. The reason for the gender differences is not known, but comorbidity and a potentially greater risk of adverse
reactions in women may be contributory factors. The different views of doctors providing treatment may also play a part.
