[Myocardial infarction in patients below the age of 40 (author's transl)]
Insights
Young males experiencing myocardial infarction, particularly heavy smokers with stressful jobs, face fewer early complications. However, they are at higher risk for long-term cardiac rhythm disorders like ventricular tachycardia.
Area of Science:
- Cardiology
- Internal Medicine
- Preventive Cardiology
Background:
- Myocardial infarction (MI) typically affects older individuals.
- Understanding MI in younger populations is crucial for targeted prevention and management.
Purpose of the Study:
- To compare the characteristics and outcomes of myocardial infarction in patients under 40 years of age versus older patients.
- To identify risk factors and etiological factors for MI in young adults.
Main Methods:
- Retrospective analysis of 35 patients under 40 with MI admitted to the National Institute of Cardiology's CCU.
- Comparison of the young cohort with a control group of older MI patients.
- Analysis of risk factors, clinical presentation, early hospital course, and long-term follow-up data.
Main Results:
- Young MI patients were predominantly male, heavy smokers, and engaged in intellectually demanding or stressful occupations (e.g., taxi drivers).
- Early hospital outcomes were better in the younger group, with no reported cardiac failure, cardiogenic shock, or mortality.
- Long-term follow-up revealed a higher incidence of premature ventricular contractions (PVCs) and ventricular tachycardia in younger patients.
- Younger patients showed a higher prevalence of left coronary artery lesions.
Conclusions:
- Myocardial infarction in young individuals is strongly associated with smoking and lifestyle-induced stress.
- While young MI patients experience better early prognoses, they are prone to long-term cardiac rhythm disturbances.
- Targeted interventions focusing on smoking cessation and stress management are vital for this demographic.
Abstract:
During the last 4 years 2040 patients with myocardial infarction were admitted to the C.C.U. of the National Institute of Cardiology. Thirty five patient under 40 years of age were studied. Three had Rheumatic heart disease and in 32 the etiology of the myocardial infarction was probably coronary atherosclerosis. The 32 cases under 40 years of age were compared to a group of patients with myocardial infarction older than 40 years of age. A great predominance of myocardial infarction was found in young males which were heavy smokers. There were no significant differences with the presence of obesity and arterial hypertension. In the younger group, myocardial infarction were more frequent in those with intellectual activity and in taxi drivers. The early hospital course was better in the young group they did not have cardiac failure, cardiogenic shock and none died. However, in the long term follow up the younger group had more P.V.C. and ventricular tachycardia. The cardiography of the younger showed an important predominance of lesions in the left coronary artery. It is concluded that in young people, myocardial infarctions seems to occur primarily in smokers with stress in their Kind of living. These patients seem to have less complications in the early and long term courses. However, more cardiac rhythm disorders are present.
