Insights
Coronary artery disease patients often have carotid artery stenosis, increasing risks. Screening for carotid stenosis is recommended, particularly before coronary artery bypass grafting, using Doppler sonography.
Area of Science:
- Cardiovascular Medicine
- Vascular Surgery
- Diagnostic Imaging
Background:
- Coronary artery disease (CAD) frequently coexists with carotid artery stenosis.
- 9-28% of CAD patients have concurrent carotid stenosis.
- Predictors include age, smoking, diabetes, hypertension, multivessel CAD, and peripheral arterial disease.
Purpose of the Study:
- To highlight the prevalence and significance of carotid artery stenosis in CAD patients.
- To emphasize the need for screening in specific patient groups.
- To recommend appropriate screening methods.
Main Methods:
- Literature review of studies on concomitant CAD and carotid artery stenosis.
- Identification of risk factors and prognostic implications.
- Evaluation of diagnostic tools for screening.
Main Results:
- Concomitant CAD and carotid stenosis are associated with poorer long-term prognosis.
- Unstable coronary syndromes and elevated inflammatory markers (CRP, fibrinogen) correlate with higher prevalence.
- Advanced age, smoking, diabetes, hypertension, multivessel CAD, and PAD are key predictors.
Conclusions:
- Patients with CAD require screening for carotid artery stenosis.
- Screening is particularly crucial before planning coronary artery bypass grafting.
- Continuous wave Doppler and color-coded duplex sonography are effective screening methods.
Abstract:
Carotid stenosis is frequent in patients with coronary artery disease (CAD). In the literature, 9-28% of patients with CAD have additional carotid artery stenosis, predictors of which are advanced age, smoking, diabetes mellitus, arterial hypertension, coronary multivessel disease, and peripheral arterial disease. Moreover, patients with unstable coronary syndromes and those with elevated inflammatory markers such as C-reactive protein or fibrinogen more often have concomitant CAD and carotid artery stenosis. The long-term prognosis of these patients is worse than with CAD only. Therefore, patients with CAD should be screened for additional carotid artery stenosis, especially if coronary artery bypass grafting is planned. Continuous wave Doppler sonography and color-coded duplex sonography are suitable methods to screen for carotid artery stenosis.
