Insights
Preoperative coronary computed tomography angiography (CTA) screening for patients undergoing carotid artery stenosis treatment can detect asymptomatic coronary artery disease (CAD). Early detection and treatment of CAD improve long-term patient prognosis.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Background:
- Carotid artery stenosis and coronary artery disease (CAD) frequently coexist.
- Concurrent conditions necessitate integrated treatment strategies.
- One condition significantly impacts the management of the other.
Purpose of the Study:
- To evaluate the utility of coronary computed tomography angiography (CTA) as a preoperative assessment tool for patients with carotid artery stenosis.
- To determine the prevalence of coronary artery disease in patients undergoing treatment for carotid artery stenosis.
- To assess the impact of preoperative coronary artery screening on treatment decisions and patient outcomes.
Main Methods:
- Retrospective review of carotid endarterectomy (CEA) and carotid artery stenting (CAS) cases.
- Analysis of preoperative coronary CTA findings in patients with carotid artery stenosis.
- Review of concurrent coronary artery disease complications and interventions.
Main Results:
- Coronary artery stenosis was identified in 32.6% of CEA patients and 41.8% of CAS patients who underwent preoperative coronary CTA.
- A significant proportion of patients (13.2% CEA, 11.5% CAS) received percutaneous coronary intervention (PCI).
- Preoperative coronary CTA was performed in a high percentage of patients (81.1% CEA, 74.3% CAS).
Conclusions:
- Preoperative coronary CTA effectively identifies asymptomatic coronary artery lesions in patients with carotid artery stenosis.
- Screening for coronary artery disease is crucial, even in patients without typical cardiac symptoms.
- Integrating coronary artery screening and treatment into carotid artery stenosis management improves long-term prognosis.
Background:
Carotid artery stenosis and coronary artery disease (CAD) often occur simultaneously, with one being an important risk factor in the treatment of the other. This study aimed to perform coronary computed tomography angiography (CTA) as a preoperative evaluation for carotid artery stenosis treatment.
Methods:
We retrospectively reviewed cases of carotid endarterectomy (CEA) and carotid artery stenting (CAS) performed at our hospital as well as CAD complications.
Results:
Among the 54 and 166 CEA and CAS cases from May 2014 to February 2022, 53 and 148 cases were analyzed for atherosclerotic stenosis, respectively. Among those who underwent CEA and CAS, 7 (13.2%) and 17 (11.5%) received percutaneous coronary intervention (PCI), 44 (83%) and 97 (65.5%) received symptomatic carotid stenosis treatment and 43 (81.1%) and 110 (74.3%) received preoperative coronary CTA, respectively. Coronary artery stenosis was noted in 14 (32.6%) and 46 (41.8%) patients who had undergone CTA in the CEA and CAS groups, respectively. PCI before carotid treatment was performed in two cases in the CEA group (3.8% of all patients who had undergone CEA) and eight cases in the CAS group (5.4% of all patients who had undergone CAS).
Conclusion:
Screening may detect asymptomatic coronary artery lesions in carotid artery stenosis even in patients without chest symptoms and suspicion of ischemic heart disease. Preoperative coronary artery screening is important considering that pre and postoperative coronary artery treatment may improve long-term prognosis.
