Title: Giving Omega-3 Fatty Acids to Elderly Patients Diagnosed With Acute Myocardial Infarction to Investigate the Effect on Cardiovascular Morbidity and Mortality
Brief Summary: The aim of the present study is to investigate the possible effects of supplementation with 1.8 g/day of n-3 polyunsaturated fatty acids on cardiovascular morbidity and mortality during a follow-up period of 2 years in an elderly population after having experienced an acute myocardial infarction.

The hypothesis is that this supplementation on top of modern therapy will reduce the combined cardiovascular end-point of death, non-fatal myocardial infarction, stroke, revascularizations or hospitalization for new or worsened heart failure with at least 30%.


Options:
A: The Alpha Omega Cohort is a prospective cohort study. The cohort originated from the Alpha Omega Trial, a 40-month intervention study of low doses of n-3 fatty acids (in margarine spreads) and cardiovascular events (NCT00127452). The in/exclusion criteria were defined for the Alpha Omega Trial.

Inclusion criteria:

* Men and women
* Aged 60 through 80 y
* Verified clinically diagnosed myocardial infarction up to 10 y before entry into the study
* Written informed consent

Exclusion criteria:

* Living in a nursing home or other institution
* Participation in another scientific study
* Habitual margarine intake \< 10 g per day
* Habitual fish intake \> 150 g per day
* Habitual alcohol intake \> 6 drinks per day
* Use of fish oil capsules or other supplements containing omega-3 fatty acids
* Presence of cancer with \< 1 y of life expectancy
* Cognitive impairment, as indicated by the Mini Mental State Examination (score \<= 21)
* Unintended weight loss \> 5 kg in the past year
* Lack of facilities for cooled margarine storage at home
* Inability or unwillingness to comply with study procedures
B: Inclusion Criteria:

* In- and outpatients of the Neurology Department of the CHL and their family members
* Carotid atherosclerosis assessed by B-mode ultrasound of at least 20% lumen reduction
* No acute stroke/TIA/amaurosis fugax (at least 3 months ago)
* Temporal ultrasound window suitable for recording of the middle cerebral artery
* Ability to give informed consent

Exclusion Criteria:

* No signed informed consent
* patient not able to give informed consent
C: Inclusion Criteria:

* Patients with acute myocardial infarction discharged from hospital alive

Exclusion Criteria:

* Being part of another randomized trial
* Documented intolerance for omega-3 fatty acids
* Additional disease state that is thought to be incompatible with compliance to the study drugs
* Additional disease state thought to reduce survival for the follow-up time of 2 years
D: General Inclusion Criteria:

1. Clinical signs and symptoms consistent with the diagnosis of an acute ischemic stroke, and subject belongs to one of the following subgroups:

   1. Subject has failed IV t-PA therapy (defined as a confirmed persistent occlusion 60 min after administration)
   2. Subject is contraindicated for IV t-PA administration
2. Age ≥18
3. Baseline NIHSS ≥10 (assessed within one hour of measuring core infarct volume)
4. Subject can be randomized between with 6 to 24 hours after time last known well
5. No significant pre-stroke disability (pre-stroke mRS must be 0 or 1)
6. Anticipated life expectancy of at least 6 months
7. Subject willing/able to return for protocol required follow up visits
8. Subject or subject's Legally Authorized Representative (LAR) has signed the study Informed Consent form\*

   * If approved by local ethics committee and country regulations, the investigator is allowed to enroll a patient utilizing emergency informed consent procedures if neither the patient nor the representative or person of trust is available to sign the informed consent form. However, as soon as possible, the patient is informed and his/her consent is requested for the possible continuation of this research. (Not applicable to U.S. Sites.)

Imaging Inclusion Criteria:

1. \< 1/3 MCA territory involved, as evidenced by CT or MRI
2. Occlusion of the intracranial ICA and/or MCA-M1 as evidenced by MRA or CTA
3. Clinical Imaging Mismatch (CIM) defined as one of the following on MR-DWI or CTP-rCBF maps:

   1. 0-\<21 cc core infarct and NIHSS ≥ 10 (and age ≥ 80 years old)
   2. 0-\<31 cc core infarct and NIHSS ≥ 10 (and age \< 80 years old)
   3. 31 cc to \<51 cc core infarct and NIHSS ≥ 20 (and age \< 80 years old)

General Exclusion Criteria:

1. History of severe head injury within past 90 days with residual neurological deficit, as determined by medical history
2. Rapid improvement in neurological status to an NIHSS \<10 or evidence of vessel recanalization prior to randomization
3. Pre-existing neurological or psychiatric disease that would confound the neurological or functional evaluations, e.g. dementia with prescribed anti-cholinesterase inhibitor (e.g. Aricept)
4. Seizures at stroke onset if it makes the diagnosis of stroke doubtful and precludes obtaining an accurate baseline NIHSS assessment
5. Baseline blood glucose of \<50mg/dL (2.78 mmol) or \>400mg/dL (22.20 mmol)
6. Baseline hemoglobin counts of \<7 mmol/L
7. Baseline platelet count \< 50,000/uL
8. Abnormal baseline electrolyte parameters as defined by sodium concentration \<130 mmol/L, potassium concentration \<3 mEq/L or \>6 mEq/L
9. Renal failure as defined by a serum creatinine \>3.0 mg/dL (264 µmol/L) NOTE: subjects on renal dialysis may be treated regardless of serum creatinine levels
10. Known hemorrhagic diathesis, coagulation factor deficiency, or on anticoagulant therapy with INR \> 3.0 or PTT \> 3 times normal. Patients on factor Xa inhibitor for 24-48 hours ago must have a normal PTT.
11. Any active or recent hemorrhage within the past 30 days
12. History of severe allergy (more than rash) to contrast medium
13. Severe, sustained hypertension (Systolic Blood Pressure \>185 mmHg or Diastolic Blood Pressure \>110 mmHg) NOTE: If the blood pressure can be successfully reduced and maintained at the acceptable level using medication the subject can be enrolled
14. Female who is pregnant or lactating at time of admission
15. Current participation in another investigational drug or device study
16. Presumed septic embolus, or suspicion of bacterial endocarditis
17. Treatment with any cleared thrombectomy devices or other intra-arterial (neurovascular) therapies prior to randomization

Imaging Exclusion Criteria:

1. Evidence of intracranial hemorrhage on CT/MRI
2. CTA or MRA evidence of flow limiting carotid dissection, high-grade stenosis, or complete cervical carotid occlusion requiring stenting at the time of the index procedure (i.e., mechanical thrombectomy).
3. Excessive tortuosity of cervical vessels on CTA/MRA that would likely preclude device delivery/deployment
4. Suspected cerebral vasculitis based on medical history and CTA/MRA
5. Suspected aortic dissection based on medical history and CTA/MRA
6. Intracranial stent implanted in the same vascular territory that would preclude the safe deployment/removal of the Trevo device
7. Occlusions in multiple vascular territories (e.g., bilateral anterior circulation, or anterior circulation/vertebrobasilar system) as confirmed on CTA/MRA, or clinical evidence of bilateral strokes or strokes in multiple territories
8. Significant mass effect with midline shift as confirmed on CT/MRI
9. Evidence of intracranial tumor (except small meningioma) as confirmed on CT/MRI
