[Myocardial infarction in the young: evolution and clinico-coronarographic correlation (author's transl)]
Insights
Young patients experiencing acute myocardial infarction often have multiple risk factors like hyperlipidemia and smoking. Severity of coronary artery disease significantly impacts long-term outcomes, including angina and reinfarction.
Area of Science:
- Cardiology
- Vascular Medicine
Context:
- Acute myocardial infarction (AMI) in patients under 40 is uncommon but warrants investigation into risk factors and long-term prognosis.
- Coronary arteriography is crucial for assessing the extent of coronary artery disease (CAD) in young AMI survivors.
Purpose:
- To evaluate the long-term outcomes of young patients (≤40 years) following an acute myocardial infarction.
- To identify common risk factors and their correlation with disease severity and clinical events in this cohort.
Summary:
- This study followed 50 patients with early-onset AMI for a mean of 56 months post-coronary arteriography.
- Hyperlipidemia (60%) and smoking (82%) were prevalent risk factors; 37 patients had multiple risk factors.
- Five-year mortality was 14%, linked to symptom severity. Patients with single-vessel disease or normal arteriograms had better outcomes regarding angina and reinfarction compared to those with multi-vessel disease.
Impact:
- Findings highlight the significant role of multiple risk factors and CAD severity in the prognosis of young myocardial infarction patients.
- This research underscores the need for early risk factor modification and aggressive management in younger populations to prevent recurrent events and improve long-term survival.
Abstract:
Fifty patients who suffered from an acute myocardial infarction at age 40 or below and underwent coronary arteriography, were studied from 8 to 184 months after the infarction (mean follow-up 56 months). Hyperlipidaemia (60%) and cigarette-smoking (82%) were the most common risk factors, while hypertension and diabetes mellitus were found in 10% of all patients. Thirty-seven patients had two or more risk factors. Preinfarction angina was present in 7 subjects. Death rate was 14% within five years and was related to the severity of symptoms. Out of the patients with normal coronary arteriogram (6 patients) or with a single vessel disease 21 were free of angina and 30 did not suffer a reinfarction. Out of 17 patients with two or more coronary vessel disease, angina was present in 14 and reinfarction was seen in 5.
