Not applicable |
Male and Female
1. Patients with asymptomatic atherosclerotic carotid artery stenosis with area stenosis of more than 60% as diagnosed by carotid artery ultrasonography, and who will be undergoing medical treatment.
2. Patients who have undergone MRI during the course of treatment, and in whom MRI plaque assessment has revealed the presence of IPH.
3. Patients who have provided sufficiently informed consent to participate in the study.
4. Patients who are capable of attending outpatient appointments and are expected to live more than 5 years after enrollment.
1. Patients who cannot undergo MRI
2. Patients who have previously undergone or are currently receiving radiotherapy to the head and neck region.

Parameters Investigated
1. At enrollment
Basic data on the following parameters will be collected from medical records and imaging investigations: 1) age and sex; 2) medical history (hypertension: blood pressure over 140/90 mmHg during any examination from the previous 3 months, or taking antihypertensive medication; hypercholesterolemia: LDL cholesterol over 140 mg/dl, or taking lipid-lowering medication; diabetes: hemoglobin A1c over 6.1%, or taking oral blood sugar-lowering medication or insulin; cerebral infarction: diagnosed at a medical institution; ischemic heart disease: identification of coronary artery stenosis over 75%, or previous treatment; atrial fibrillation: diagnosed at a medical institution; valve disease: diagnosed at a medical institution); 3) lifestyle (smoking: previous or current smoker; excessive alcohol consumption: alcohol intake over 150 g/week); 4) blood tests (regular biochemistry tests and sLOX-1 antibody titer); and 5) cranial MRI: including diffusion-weighted imaging and fluid-attenuated inversion recovery imaging; 6) imaging evaluation of carotid artery stenosis (carotid artery ultrasonography, carotid artery MRI).
2. Follow-up investigations
Examinations will be carried out every 6 months, and carotid artery ultrasound and carotid artery MRI every 12 months. Examinations, blood tests, carotid artery ultrasound, carotid artery MRI, and cranial MRI will be carried out until the end of the observation period or an endpoint is reached.
