Myocardial infarction among men below age 40
Insights
Young men experiencing acute myocardial infarction (heart attack) often have significant risk factors like smoking and high cholesterol. A small number of these patients, free from risk factors, showed normal coronary arteries.
Area of Science:
- Cardiology
- Preventive Medicine
- Epidemiology
Background:
- Acute myocardial infarction (heart attack) in young men under 40 is uncommon but serious.
- Understanding risk factors is crucial for early detection and prevention in this demographic.
Purpose of the Study:
- To investigate the conventional risk factors associated with acute myocardial infarction in men under 40.
- To identify patterns and characteristics of young males experiencing heart attacks.
Main Methods:
- Retrospective study of 36 male patients under 40 diagnosed with acute myocardial infarction over 6 years in Göteborg.
- Comparison of 25 surviving patients with a random population sample regarding risk factors.
- Coronary angiography performed on 18 patients.
Main Results:
- Smoking and high plasma cholesterol were prevalent risk factors among young male patients.
- No significant differences in blood pressure levels were observed between patients and the general population.
- Two patients (11% of those with angiography) had normal coronary arteries and were free from risk factors.
- Of the 16 patients with affected coronary arteries, 10 had single-vessel disease.
Conclusions:
- Smoking and hypercholesterolemia are key risk factors for acute myocardial infarction in young men.
- A subset of young men experiencing heart attacks may have normal coronary arteries and lack traditional risk factors.
- Further research is needed to understand the etiology in patients without identifiable risk factors.
Abstract:
Studies were made in Göteborg over a period of 6 years of all cases of acute myocardial infarction diagnosed among men below the age of 40. Thirty-six cases were registered and 8 of these died outside hospital. Three patients died early during the hospital stay. The remaining 25 patients were compared with a random sample from the general population in Göteborg with respect to conventional risk factors. Smoking, and high plasma cholesterol values were dominating findings among the patients, whereas there was no significant differences in blood pressure levels. Coronary angiography was performed in 18 patients of whom 2 showed normal coronary arteries and left ventricular angiograms. These 2 patients were the only ones free from risk factors. Of the remaining 16 patients, 10 had only one vessel affected.
