Myocardial infarction (MI) in young adults under 35 is concerning. This study found high mortality and identified key risk factors like hyperlipoproteinemia, smoking, and family history, though diagnostic accuracy needs improvement.
Area of Science:
- Cardiology
- Public Health
Background:
- Myocardial infarction (MI) in individuals under 35 is relatively rare but warrants investigation.
- Evaluating diagnostic accuracy and long-term outcomes for young MI patients is crucial.
Purpose of the Study:
- To assess the validity of myocardial infarction diagnoses in young patients.
- To determine the long-term prognosis and identify risk factors for MI in this demographic.
Main Methods:
- Retrospective analysis of 30 patient histories from the Uppsala hospital region's central data register.
- Inclusion criteria focused on myocardial infarction in subjects younger than 35.
- Follow-up examinations for survivors extended up to 11 years post-initial hospitalization.
Main Results:
- Hospital mortality for 14 subjects with MI and coronary atheromatosis was 29%, rising to 43% during follow-up.
- Six of seven investigated survivors in this group remained symptom-free and employed full-time.
- Identified risk factors included hyperlipoproteinemia, smoking, and a family history of ischemic heart disease.
Conclusions:
- Diagnostic validity of central data registers for MI requires further evaluation, as 10 initial diagnoses were incorrect.
- Despite high mortality, survivors of MI with coronary atheromatosis under 35 can achieve good long-term functional status.
- Hyperlipoproteinemia, smoking, and heredity are significant risk factors for early-onset ischemic heart disease.
Abstract:
The occurrence of myocardial infarction (MI) in subjects younger than 35 years of age is the subject of this work. The aims were to evaluate the validity of the diagnosis and to study the long-term prognosis for these patients. Through the central data register of all hospital discharges in the Uppsala hospital region (approximately 1.25 mill. inhabitants) 30 patient histories were obtained. They were carefully evaluated and all survivors were invited to an examination at the Department of Cardiology. The follow-up period from the initial hospital stay was up to 11 years. The hospital mortality among 14 subjects with MI and coronary atheromatosis was 29%, increasing to 43% in the follow-up period. Six of the seven investigated survivors in this group were symptom-free and full-time employed. Hyperlipoproteinemia, smoking and heredity for ischemic heart disease seemed to be the most important risk factors among the 14 subjects in this group. Further studies are necessary to evaluate the validity of diagnoses obtained from central data register. In ten patients the initial diagnosis had been incorrect.
