Critères
Tous
Inclusion criteria:
Patient should have the following:
Patient with:
1. Cerebral infarction (CI) proven by neuro-imaging (MRI or head-CT), immediately once
the neurologic deficit is stabilized (investigator judgement) if the patient was on
antiplatelet agent monotherapy after the qualifying event, or after 21 days if the
patient was on clopidogrel plus aspirin after the qualifying event, or after 21 to
30 days if the patient was on ticagrelor plus aspirin after the qualifying event
(TIA with documented ischemic lesion (MRI or CT) in the appropriate area
corresponding to the symptoms will be considered CI, following the current
definition)
2. Or TIA lasting more 10 minutes or more (with motor symptoms or aphasia/dysarthria or
visual defect), with total resolution and no brain lesion on neuro-imaging (TIA) and
with ipsilateral carotid stenosis that was revascularized (endarterectomy or
stenting) or with ipsilateral, potentially causal intracranial stenosis ≥70%) if the
patient was on antiplatelet agent monotherapy after the qualifying event, or after
21 days if the patient was on clopidogrel plus aspirin after the qualifying event,
or after 21 to 30 days if the patient was on ticagrelor plus aspirin after the
qualifying event
3. and documented atherosclerotic stenosis:
1. presence of carotid atherosclerotic stenosis (on the basis of carotid duplex,
CTA, MRA, XRA - only the report will be required to document atherosclerotic
disease) ipsilateral to the cerebral ischemic symptoms (stenosis defined by
luminal narrowing ≥30%, judgement of the investigator)
2. or presence of atherosclerotic stenosis of another cerebral artery (documented
vertebral artery stenosis, basilar artery stenosis, other intracranial artery
stenosis) ipsilateral to the ischemic area (stenosis defined by luminal
narrowing ≥30%, judgement of the investigator)
3. or presence of atherosclerotic disease of the aortic arch with a plaque ≥4mm in
thickness with or without superimposed thrombus, or a plaque <4 mm with a
superimposed mobile thrombus (detected by transesophageal echocardiography or
CT angiography)
4. with no clear indication of colchicine treatment (gout, Mediterranean fever) and
with an indication to long-term antiplatelet therapy (no clear indication to oral
anticoagulant)
5. age equal or above 18
6. Rankin score less than ≤4 (ranges from 0 to 6, with 0 indicating no symptoms, 1 no
disability, 2 to 3 needing some help with daily activities, 4 to 5 dependent or
bedridden, and 6 death),
7. fully informed and signed inform consent
8. with social security number.
9. medical examination before the participation to the research
10. Under contraception in case of childbearing potential (highly effective: 1) combined
(estrogen and progestogen containing) hormonal contraception associated with
inhibition of ovulation et 2) progestogen-only).
11. Pregnancy test for women of childbearing potential
