Acute myocardial infarction in young adults: incidence, risk factors and prognosis
INTRODUCTION: The incidence of acute myocardial infarction (AMI) might not be decreasing as much among
young adults as in the general population in recent years. The goal of our study was to explore incidence,
risk factors and prognosis of AMI among young patients in Iceland.
MATERIAL AND METHODS: This was a retrospective case control study. The data was obtained from
the SCAAR-SWEDEHEART database, medical records from Landspitali University Hospital and the
death register from the Directorate of Health. The epidemiology of women ≤55 years and men ≤50 years
diagnosed with AMI (STEMI/NSTEMI) in Iceland in 2014-2020 was compared with older patients.
RESULTS: Of all the cases (2852), 344 patients (12%) were young. No change was demonstrated in the
incidence of AMI in the young patients during the study period. The proportion of STEMI was higher among
young patients (52% vs. 35%, p<0.001). Smoking (50% vs. 26%, p<0.001) and obesity (BMI>30 kg/m2)(47%
vs. 36%, p<0.01) were more prevalent in younger patiens compared to the older. Older patients were more
likely to die in the year following the AMI, both from all-cause (7% vs. 3%, p<0.05) and cardiovascular
mortality (7% vs. 3%, p<0.05). A difference in recurrent AMI between the young and older patients was not
demonstrated (2% vs. 3%, p=0.3).
CONCLUSION: During the research period, a change in the incidence of AMI among young patients, was not
demonstrated. Younger patients with AMI have different risk factors than older patients, they have lower
mortality rate but the same risk of recurrent AMI.
