This prospective observational cohort study aims to investigate the prevalence and clinical significance of head and neck arterial stenosis in patients with coronary artery disease (CAD) undergoing or scheduled for percutaneous coronary intervention (PCI). Using Doppler ultrasound as the primary screening tool, the study will assess the degree of stenosis and evaluate the impact of different combined treatment strategies on patient outcomes. The research will provide real-world evidence to optimize integrated care approaches for patients with comorbid cardiovascular and cerebrovascular diseases.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group 1: PCI + Carotid Revascularization | Patients diagnosed with both coronary artery disease and significant carotid artery stenosis requiring intervention, who received both PCI and carotid revascularization. |
| |
| Group 2: PCI + Observation of Carotid Stenosis | Patients who underwent PCI for coronary artery disease, with no carotid stenosis or with carotid stenosis not requiring or not receiving interventional treatment. |
| |
| Group 3: Observation Only (No PCI + No CAS) | Patients who did not undergo PCI and either had no carotid artery stenosis or were managed medically for carotid stenosis without any revascularization. |
