Insights
Smoking is a key risk factor for carotid artery stenosis, unlike peripheral arterial occlusive disease (PAOD) where diabetes is less common. These findings suggest different causes for vascular disease in the neck and lower limbs.
Area of Science:
- Vascular Medicine
- Cardiovascular Epidemiology
- Cerebrovascular Disease
Context:
- Peripheral arterial occlusive disease (PAOD) is often misdiagnosed and classic risk factors like dyslipidemia are not always present.
- Understanding risk factors for carotid artery stenosis is crucial for early diagnosis and intervention.
Purpose:
- To investigate the prevalence of common vascular risk factors (smoking, hypertension, hyperglycemia, dyslipidemia) in patients with extracranial carotid artery stenosis.
- To compare these risk factors with those found in patients with lower limb PAOD.
- To assess the association between risk factors, carotid atheromatous lesions, and ischemic cardiomyopathy.
Summary:
- A retrospective analysis of 636 patients (age > 40, carotid stenosis > 40%) revealed smoking as a prevalent risk factor for carotid lesions.
- Diabetes was less frequently associated with carotid stenosis compared to PAOD.
- A history of smoking (current or former) was common among patients with carotid stenosis.
Impact:
- Highlights distinct etiopathogenetic mechanisms for vascular disease in the carotid arteries versus the lower limbs.
- Informs targeted screening and prevention strategies for cerebrovascular disease.
- Emphasizes the significant role of smoking in carotid artery disease.
Background And Aims:
Recent studies have underlined a significant incidence of peripheral arterial occlusive disease (PAOD) of the lower limbs in the general population which is often wrongly diagnosed. The "classic" risk factors--like dyslipidemia--are not always present in significant percentages in patients suffering from PAOD of the lower limbs. The aim of this study was to evaluate the incidence of the most common vascular risk factors (smoking, hypertension, hyperglycemia, dyslipidemia) in patients suffering from stenosing lesions of the extracranial carotid axes, comparing the data with similar findings in lower limbs. Moreover, the authors evaluated the association between these risk factors, carotid atheromatous lesions and ischemic cardiomyopathy (CI).
Methods:
A retrospective study was performed to evaluate the data from 1643 patients examined consecutively. A total of 636 (age > 40, carotid stenosis > 40%, presence of risk factors) were considered eligible.
Results:
The results showed that, contrary to the findings in patients suffering from PAOD, diabetes was not among the most frequently associated risk factors, whereas a relatively large number of patients had a history of smoking, including both smokers and ex-smokers.
Conclusions:
The difference in the most frequent risk factors identified for PAOD and carotid lesions suggests different etiopathogenetic mechanisms for the two districts.
