Brief Summary
Magnetic resonance imaging (MRI) is commonly used in healthcare, and sometimes it shows small areas of brain damage called Covert Brain Infarcts (CBIs). These are usually found by chance when people have scans for things like headaches or dizziness. Although CBIs don't cause symptoms at the time, they are linked to a higher risk of future stroke and death. There is currently no standard treatment for CBIs, and doctors have different approaches-some give stroke-preventing medication (like antiplatelets or statins), while others don't treat at all. This is mostly because there isn't enough research yet. This study will test whether stroke-preventing treatments help people with CBIs. It will also look at whether having a CBI increases the risk of dementia, and whether treatment might lower that risk.

Outcome Measures
Primary Outcomes (2)
Major Adverse Cardiac and Cerebral Events (MACCE) at 12 and 36 months
MACCE are defined as the occurrence of any of the following events * All cause death: Death from any cause * Acute myocardial infarction: Admission with a discharge diagnosis of ST-elevation myocardial infarction (STEMI) and non-ST elevation myocardial infarction (NSTEMI) and * Stroke: AIS\* or Intracerebral hemorrhage (non-traumatic) \*Including Transient Ischemic Attack (TIA) with evidence of brain tissue infarction i.e. remission of symptoms within 24 hours but who have an acute ischemic lesion on diffusion weighted imaging MRI. All events qualifying for a MACCE event will be adjudicated by the Clinical event committee. Accepted timeframe for evaluation is +/- 30 days
12 months and 36 months post-randomization.
Major and fatal bleeding at 12 and 36 months
Major and fatal bleeding events are defined according to criteria established by the International Society on Thrombosis and Haemostasis (ISTH): * Fatal bleeding, and/or * Symptomatic bleeding in a critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intra-articular, pericardial, or intramuscular with compartment syndrome, and/or * Bleeding leading to a drop in hemoglobin of ≥20 g/L (1.24 mmol/L), or requiring transfusion of two or more units of whole blood or red cells. All qualifying events will be adjudicated by an independent Clinical Event Committee (CEC). The accepted time window for assessment is ±30 days.
12 months and 36 months post-randomization.
Secondary Outcomes (11)
All-cause dementia
12 months and 36 months post-randomization.
Cardiovascular-related mortality
12 months and 36 months post-randomization.
Cognitive decline
After 12 months and a end of treatment at 36 months
Serious adverse event (SAE)
From enrollment to the end of treatment at 36 months
Baseline MRI risk markers, quantified using the ordinal simplified SVD-score (small vessel disease) score
After 12 months and at the end of treatment at 36 months
- +6 more secondary outcomes
Other Outcomes (4)
MRI-based assessment of small vessel disease progression (sub-study)
After 36 months (+/- 1 months)
MRI-based assessment of white matter lesion (WML) volume growth
36 months (+/- 1 month)
Carotid plaque quantification on ultrasound
At baseline
- +1 more other outcomes
Study Arms (4)
Group A: Platelet inhibitor - no Statin ("APT alone")
EXPERIMENTALAll patients will initiate treatment with Aspirin or Clopidogrel. The decision on which of the two drugs to initiate is at the discretion of the treating physician/center.
Group B: Statins - no Platelet inhibitor ("Statin alone").
EXPERIMENTALPatients will be treated with high-intensity statin therapy (Atorvastatin 40 mg once daily or Rosuvastatin 20 mg once daily)
Group C: Statins - Platelet inhibitor ("APT AND statin")
EXPERIMENTALBoth types of medication are initiated as described in group A and B
Group D: No Statins - no Platelet inhibitor (current standard treatment)
NO INTERVENTIONThis group follows the current European recommendations of primary prevention which do not include statins and APT agents. If statins and/or platelet inhibitors are started during the study-period it should adhere to primary prevention guidelines. All four groups receive advice on lifestyle optimization and blood pressure management.
Interventions
Daily dose 75 mg p.o.
Daily dose 20 mg p.o. (10 mg once daily for the first 4 weeks, then 20 mg once daily for the remainder of the study period if tolerated). If Rosuvastatin 20 mg is not tolerated, a dose reduction to 10 mg is allowed.
Daily dose 40 mg p.o. If Atorvastatin 40 mg is not tolerated, a dose reduction to 20 mg is allowed.
Daily dose 75 mg to 100 mg p.o.
Eligibility Criteria
You may qualify if:
- MRI demonstrating a lacunar infarct (acute/subacute/chronic) without prior stroke/TIA symptoms. (A round or ovoid, subcortical, fluid-filled cavity (signal similar to cerebrospinal fluid (CSF)) between 3 and 15 mm in diameter and demonstrating a peripheral T2/FLAIR hyperintense rim of marginal gliosis. For infratentorial lesions the hyperintense rim may be less marked and a complete ring is not required) OR
- MRI demonstrating a cortical infarct (acute/subacute/chronic) without prior stroke/TIA symptoms (A cortical infarct is defined as a fluid-filled cavity (signal similar to CSF) in the cortex, juxtacortical region or cerebellar cortex and with a ring of T2/FLAIR hyperintense lesions or as cortical T2/FLAIR lesions without a fluid-filled cavity with presumed vascular origin. Both supra- and infratentorial lesion will be included) AND Life expectancy \> 12 months AND Predominantly independent in actives of daily living (mRS score ≤ 3) AND Age ≥ 50 years
You may not qualify if:
- History of stroke/TIA
- High risk of bleeding (e.g., recent or recurrent gastrointestinal or genitourinary bleeding associated with a decrease in hemoglobin levels of at least 1 mmol/L, active peptic ulcer disease, MRI with cortical siderosis and/or prior lobar hemorrhage)
- Indication for long-term use of anticoagulants (e.g. deep vein thrombosis, pulmonary embolism, atrial fibrillation, and rarer indications; such as mechanical heart valve, antiphospholipid antibody syndrome etc.)
- Concurrent indication for lipid-lowering treatment and/or platelet-inhibitors for secondary cardiovascular prevention (ischemic heart disease, recent stenting, ischemic stroke, revascularization surgeries, lower-extremity atherosclerotic arterial disease etc.)
- Co-existing progressive neurodegenerative disease including dementia or Parkinson's disease.
- Neoplastic condition that is uncontrolled or associated with an increased risk of bleeding
- Patient already on antiplatelet or anticoagulation agent, regardless of indication
- Women with a history of menopause below 12 months are only included after negative pregnancy test
