BACKGROUND The Norwegian Myocardial Infarction Registry was established in 2012 as a national quality registry. This first report from the registry presents the number
of myocardial infarctions, the treatment provided and the 30-day mortality rate for myocardial infarctions admitted to Norwegian hospitals.
MATERIAL AND METHOD All patients with myocardial infarction admitted to Norwegian hospitals in 2013 and recorded in the Norwegian Myocardial Infarction Registry are
included. The number of myocardial infarctions, patient characteristics and their treatment are indicated for myocardial infarctions with and without ST-segment elevation on ECG
(STEMI and nSTEMI). The 30-day mortality is calculated for each health region.
RESULTS In 2013, a total of 13,043 myocardial infarctions in 12,336 patients were recorded in the Norwegian Myocardial Infarction Registry. Altogether 3,658 (28 %) of the
infarctions were classified as STEMI and 9,188 (70 %) as nSTEMI. The average age at the time of the infarction was 68.1 years for men and 75.9 years for women. Percutaneous
coronary intervention was performed for a total of 2,798 (77 %) ST-segment elevation myocardial infarctions, whereas the corresponding number for nSTEMI was 3,179 (35 %).
The 30-day mortality in the entire infarction population was 10 % (< 60 years: 2 %, 60 - 69 years: 4 %, 70 - 79 years: 9 %, > 80 years: 20 %). We found no differences in mortality
between health regions or between men and women.
INTERPRETATION This first report from the Norwegian Myocardial Infarction Registry shows that the treatment service is functioning well for most patients. Secondary
prophylaxis using drug therapy and increased use of invasive examination of patients with nSTEMI appear to be areas for improvement.
