[Myocardial infarction in young patient: Epidemiological specificities and risk factors]

Area of Science:

• Cardiology
• Vascular Medicine
• Preventive Cardiology

Background:

• Premature coronary artery disease lacks a precise definition, typically affecting individuals under 40-50 years old.
• Common risk factors include male sex, active smoking, and a family history of early heart disease.
• Young patients often present with ST-elevation myocardial infarction (STEMI) or coronary dissection, particularly women.

Purpose of the Study:

• To review the characteristics and risk factors associated with premature coronary artery disease.
• To highlight the common clinical presentations and challenges in managing early-onset heart disease.
• To discuss the long-term prognosis and underlying pathological processes.

Main Methods:

• Literature review of studies on premature coronary artery disease.
• Analysis of patient demographics and risk factor prevalence.
• Examination of clinical outcomes and management strategies.

Main Results:

• The majority of patients with premature coronary artery disease possess at least one major risk factor: male sex, smoking, or family history.
• ST-elevation myocardial infarction occurs in two-thirds of young patients.
• Coronary dissection is noted, especially in women in their 40s.

Conclusions:

• There is no specific management protocol for premature coronary artery disease.
• The long-term prognosis is often unfavorable due to the progressive nature of atherosclerosis.
• Early identification and risk factor modification are crucial for improving outcomes.
