Insights
A family history of premature coronary artery disease (CAD) significantly increases risk, even without other traditional factors. Individuals with this history require cautious management and monitoring for early detection of heart disease.
Area of Science:
- Cardiology
- Genetics
- Preventive Medicine
Background:
- Coronary artery disease (CAD) is uncommon in individuals under 40-45.
- Premature CAD's risk factors, beyond traditional ones, are not fully understood.
- Genetic predisposition may contribute to early-onset CAD.
Observation:
- A 22-year-old male presented with myocardial infarction despite lacking traditional CAD risk factors.
- His only significant risk factor was a family history of premature CAD.
- Coronary angiography revealed extensive CAD, necessitating coronary artery bypass grafting.
Findings:
- The patient recovered well post-surgery and remained symptom-free at one-year follow-up.
- No new traditional risk factors emerged during the follow-up period.
- A positive family history appears to be an independent risk factor for premature CAD.
Implications:
- Family history of premature CAD is a critical, independent risk factor.
- Individuals with a family history of early-onset CAD warrant closer monitoring.
- Proactive screening and management strategies are crucial for this high-risk group.
Abstract:
Although coronary artery disease (CAD) is not common among individuals younger than 40-45 years of age, a small percentage of this age group needs to undergo surgical revascularization because of CAD. Why some people are at higher risk of developing premature CAD is not clearly known. Increased number of traditional risk factors or genetic predisposition may play significant roles in this regard. A 22-year-old man with a negative history for all traditional risk factors except for a family history of premature CAD referred to our center due to an episode of myocardial infarction of one month's duration. He had no congenital heart disease and no hypercoagulable state, and there was a negative history of drug abuse. His coronary angiography showed extensive CAD. He underwent coronary artery bypass grafting and he left the hospital in good healthy condition. One year after surgery, his follow-up showed that he was symptom free and he still had no new traditional risk factor. It seems that a positive family history of premature CAD is an important and independent risk factor for developing premature CAD and individuals with this type of history should be treated more cautiously.
