Severe extracranial carotid atherosclerosis in young adults

Insights
Younger adults experiencing stroke often have nonatherosclerotic causes. However, for those under 45 undergoing carotid endarterectomy, smoking is the primary risk factor, alongside hyperlipidemia and family history.
Area of Science:
- Vascular Surgery
- Cerebrovascular Disease
- Cardiovascular Risk Factors
Background:
- Stroke in adults under 50 typically involves nonatherosclerotic causes.
- Atherosclerotic carotid stenosis is less commonly studied in younger populations.
Purpose of the Study:
- To investigate the risk factor profile of patients under age 45 who underwent carotid endarterectomy for severe atherosclerotic stenosis.
- To identify key risk factors differentiating younger patients with carotid atherosclerosis from older counterparts.
Main Methods:
- Retrospective review of 41 patients under age 45 who underwent carotid endarterectomy.
- Analysis of risk factors including smoking, hyperlipidemia, family history, coronary atherosclerosis, and hypertension.
Main Results:
- Smoking emerged as the most significant risk factor in this young cohort.
- Hyperlipidemia, family history, and concurrent coronary atherosclerosis were also prominent risk factors.
- Hypertension was a less critical risk factor compared to older patients with carotid disease.
Conclusions:
- Younger patients undergoing carotid endarterectomy for atherosclerotic stenosis present a distinct risk factor profile.
- Smoking cessation is crucial for younger individuals at risk of atherosclerotic carotid disease.
- Further research into nonatherosclerotic causes in younger stroke patients remains important.
Abstract:
Studies of stroke in adults under age 50 emphasize nonatherosclerotic causes. We examined the risk factor profile in 41 patients under age 45 who underwent carotid endarterectomy for severe atherosclerotic stenosis at the Cleveland Clinic Foundation from 1975 to 1990. Smoking was the strongest risk factor. Hyperlipidemia, family history, and associated coronary atherosclerosis were also major risk factors. In contradistinction to older patients with carotid disease, hypertension was a less important risk factor.
