Brief Summary

Carotid artery disease is a main cause of ischemic stroke and vascular dementia, and a highly prevalent disease. There is uncertainty about the optimal management of patients with serendipitously or systematically detected asymptomatic carotid artery disease, due to the paucity of information on the predictive features of serious vascular events. While percent diameter stenosis is currently the accepted standard to decide about local interventions (carotid artery stenting or endarterectomy), international guidelines also recommend the evaluation of qualitative features of carotid artery disease as a guide to treatment. There is, however, no agreement on which qualitative features are best predictors of events. Furthermore, a role for metabolic plaque profile, local mechanical and hemorheologic factors in triggering microembolization and silent ischemic events has been proposed from experimental studies. This inadequate knowledge leads to a poor ability to identify patients at higher risk and to an unwarranted dispersion of medical resources, lack of standardization in diagnostic methods, and the use of expensive and resource-consuming techniques. Against this background, the investigators aim at:

  1. 1.Prospectively identifying the best predictors of (silent and overt) ischemic stroke and vascular dementia in patients with asymptomatic subcritical carotid artery disease, by identifying the non-invasive diagnostic features of the "vulnerable carotid plaque" as a possible guide for optimal - local and systemic - treatment.
  2. 2.Transferring new ultrasound techniques possibly improving risk prediction to the clinical field
  3. 3.Assess whether "smart", low-cost diagnostic methods, such as ultrasound-based evaluations integrating established and advanced techniques, may yield at least the same level of prospective information as more expensive and less cost-effective techniques.

Outcome Measures

Primary Outcomes (2)

  • Number of participants developing TIA/stroke and/or subclinical ischemic lesions

    The incidence of TIA/stroke and, mainly, the development of subclinical ischemic lesions, as demonstrated by the comparative evaluation of two brain MRI, one at baseline - at the time of acquisition of the carotid plaque characteristics by the multiple techniques here used - and at a 2-year follow-up.

    2 years

  • Number of participants developing neurocognitive decline

    Neurocognitive decline, as assessed by comparative neurocognitive testing, at baseline, and at the 2-year follow-up

    2 years

Secondary Outcomes (1)

  • The cost of the least expensive effective pathway

    3 years

Eligibility Criteria

Age45 Years - 85 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients aging 45 to 85 years, with asymptomatic monolateral carotid artery lesions between 40 and 60% stenosis at carotid artery ultrasound.

You may qualify if:

  • Asymptomatic carotid artery lesions between 40 and 60%, at carotid artery ultrasound, for which lesions an interventional strategy - beside optimal medical therapy - is not clearly defined.
  • Patients with asymptomatic carotid artery stenosis higher than 60% will be enrolled when revascularization by either carotid endarterectomy (CEA) or stenting will be considered not indicated or not feasible
  • Both genders (with capping implemented in order to ensure a 50±5% balance of males to females),

You may not qualify if:

  • Severe comorbidities a priori precluding the 2-year follow-up (cachexia; end-stage cancer; severe renal/respiratory insufficiency; advanced (class IV) heart failure; atrial fibrillation and other significant arrhythmias).
  • Severe allergic diathesis; contraindications to contrast agents for angio-TC or MRI; claustrophobia; presence of prostheses/implanted electronic devices not suitable for MRI; lack of consent for any reason.
