P1749Mortality in ST segment elevation myocardial infarction treated with primary percutaneous intervention in Norway A report from the Norwegian registry of invasive cardiology (NORIC)


 
 
 Limitations of the current reports on prognosis in ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI), are that they are based on selected samples from hospitals voluntary registries, trials and surveys and thereby lack full population coverage. In contrast to most developed countries, Sweden and the UK were for a long term, the only two countries worldwide that had continuous national clinical registries for acute coronary syndrome with mandated participation for all hospitals. This is now also the case in Norway. Of all STEMIs admitted to hospital in Norway, 77% is treated with PCI (2016). Since 2013 invasive coronary procedures is registered in The Norwegian registry for invasive cardiology (NORIC).
 
 
 
 The purpose of the current report from NORIC was to assess the mortality rates in patients treated with PCI for STEMI in Norway. Moreover we sought to assess the relationship between mortality and age at admission in this population.
 
 
 
 NORIC, which is a part of the Norwegian Cardiovascular Disease Registry (NCDR), is a national person-identifiable health registry that does not require consent from the registered individual. Data were registered from 1st of January 2013 to 13th of June 2018.
 
 
 
 During this period 10524 patients were registered with a STEMI. The incidence is calculated for the years of 2015–2017 when the registry had full national coverage. The incidence of STEMI treated with PCI in Norway was (53 in 2015, 50 in 2016 and 52 in 2017 per 100 000). For patients younger than 80 years at admission, the mortality rates were 4.9%, 6.8% and 8.0% at 30 days, 365 days and 730 days respectively. For patients older than 80 years at admission the mortality rates were 8.3%, 15.6% and 19.0% at 30 days, 365 days and 730 days respectively. The mortality rates stratified by age are illustrated in figure 1.
 Survival stratified by age
 
 
 
 Mortality in STEMI patients offered primary PCI in Norway is equal or even lower than the mortality reported from well-established national registries from UK and Sweden. This indicates a well functioning treatment strategy despite challenging geography. Age is an important determinant of mortality.
