Insights
Young men experiencing myocardial infarction (MI) often have multiple risk factors, including smoking and hypertension. Significant coronary artery disease was found in 64% of patients under 40.
Area of Science:
- Cardiology
- Preventive Medicine
- Public Health
Background:
- Myocardial infarction (MI) in individuals under 40 is a growing concern.
- Understanding risk factors and disease presentation in this demographic is crucial for effective prevention and treatment strategies.
Purpose of the Study:
- To analyze the occurrence of ischemic heart disease risk factors.
- To evaluate invasive and noninvasive investigation results within one year post-MI.
- To assess the relationship between risk factors and coronary artery disease severity in young men.
Main Methods:
- Analysis of a cohort of 25 men under 40 years old after acute myocardial infarction (MI).
- Inclusion of data from invasive (coronary angiography) and noninvasive investigations.
- Assessment of risk factors including smoking, lipid metabolism, hypertension, and family history.
Main Results:
- Significant coronary artery stenosis (>50% lumen obstruction) was found in 64% of patients.
- 36% had normal or non-significant coronary artery findings.
- Dominant risk factors identified were smoking, lipid disturbances, hypertension, and positive family history.
- The average number of risk factors was higher in patients with significant coronary sclerosis (4.85) compared to those with normal findings (2.55).
- Heavy smoking combined with vigorous physical activity increased MI risk.
- No correlation was observed between coronary sclerosis extent/location and left ventricular function or wall motion.
Conclusions:
- Young men experiencing MI frequently present with significant coronary artery disease and multiple risk factors.
- Aggressive management of modifiable risk factors like smoking and hypertension is essential in this population.
- Further research is needed to explore the specific interplay of lifestyle factors and cardiovascular risk in younger individuals.
Abstract:
In a group of 25 men after myocardial infarction (MI) at an age under 40 years the occurrence of risk factors of ischaemic heart disease, the results of both invasive and noninvasive investigations as well as other special examinations within one year after the attack of acute MI were analysed. In 36% there was a normal finding or nonsignificant stenosis on the coronary arteries (less than 50% lumen obstruction at coronary angiography); a significant stenosis was found in 64%, out of which only one coronary vessel was affected in 32%. Dominant risk factors were: smoking, lipid metabolism disturbances, hypertension and a positive family history. The average number of risk factors in the group with a normal finding on the coronary arteries was 2.55, and in the group with a significant coronary sclerosis 4.85. The risk of myocardial infarction is increased by the coexistence of heavy smoking habits and vigorous physical activity. No correlation was found between the extent and location of coronary sclerosis and the functional parametres and wall motion of the left ventricle. An analysis of occupational status before MI revealed that 52% of the patients were workers, 40% professional drivers and only 8% were clerks.
