Risk factors for acute myocardial infarction among men in the subarctic area
Insights
Hypertension, family history, diabetes, and smoking are key risk factors for acute myocardial infarction (AMI) in Swedish males. Environmental and psychosocial factors also contribute to AMI risk in this subarctic population.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Ischemic heart disease mortality is notably high in Kiruna, a subarctic Swedish town.
- Understanding acute myocardial infarction (AMI) risk factors in this unique population is crucial.
Purpose of the Study:
- To identify and quantify the primary risk factors for first-time AMI in males residing in Sweden's subarctic region.
- To compare risk factor prevalence between native residents and migrants in Kiruna.
Main Methods:
- A case-control study was conducted involving a questionnaire and clinical examination.
- 219 male patients aged 35-64 with a first AMI (1973-1985) were compared to 438 age-matched controls.
Main Results:
- Key risk factors identified for AMI included hypertension (OR 3.5), family history of AMI (OR 2.2), diabetes mellitus (OR 2.2), and smoking (OR 1.7).
- Significant differences in the distribution and impact of these risk factors were observed between individuals born in Kiruna and those who migrated there.
Conclusions:
- Traditional risk factors like hypertension, family history, diabetes, and smoking are significant contributors to AMI.
- Environmental, psychosocial factors, and population dynamics warrant consideration in assessing AMI risk for men in Kiruna.
Objective:
To describe and quantify the main risk factors for acute myocardial infarction (AMI) among males in the subarctic region of Sweden.
Design:
Case-control study comprising a questionnaire and a clinical examination.
Setting:
Kiruna, a town about 100 miles north of the Arctic Circle with a very high mortality from ischaemic heart disease.
Subjects:
219 patients 35 to 64 years of age admitted to Kiruna District Hospital with a first myocardial infarction between 1973 and 1985, and 438 age-matched controls.
Results:
The main risk factors for the whole group were hypertension (odds ratio [OR] 3.5), family history of AMI (OR 2.2), diabetes mellitus (OR 2.2), and smoking (OR 1.7). The distribution and strength of the risk factors differed between Kiruna-born and migrants into the community.
Conclusion:
Apart from the traditional risk factors, environmental and psycho-social factors and population dynamics must be taken into account when assessing the risk for a man in Kiruna of developing a myocardial infarction.
