Brief Summary

Ischemic stroke is the first cause of acquired disability of the adult, the second cause of dementia and the third cause of death in the industrialized countries, what constitutes à major public health issue. Stroke is characterized by a cerebral parenchymal lesion due to an ischemic mechanism (85% of the cases) or hemorrhagic mechanism (15%). For a long time, the only approved treatment was the intravenous thrombolysis (rt-PA). Recently, thrombectomy has proven its superiority in this pathology. Cohorts of patients with stroke are rare but can be very valuable by their clinical, laboratory and imaging well documented. They are the source of new hypotheses for research or interventions as well as the quality of care assessment tool. The main objective of this project is to identify new markers: biological and imaging, treatment response and prognosis after ischemic stroke. Secondary objectives of the HIBISCUS-STROKE II cohort are to establish a clinical database, completed by biological samples and by imaging data that can be used in the following areas: Descriptive epidemiology of ischemic stroke and cerebral reperfusion, Pharmacoepidemiology and treatments observatory: safety, efficacy, indication of treatment in real life, costs Assessment of the long-term effect of the treatment on the occurrence of disability, stroke recurrence and death, Quality of life and personal, familial, professional and social consequences of stroke, Research of new diagnostic and prognostic biomarkers, Research projects. Ancillary study : Cardiac complications are the second leading cause of death after stroke. A close relationship between brain damage and heart complications, referred to as "neuro-cardiac syndrome" has been established. 20% of patients admitted for ischemic stroke present at least one major cardiac event, including acute coronary syndrome, heart failure and / or cardiac arrhythmia, within three months of the event, while 28% have a left ventricular ejection fraction less than 50%. However, the underlying pathological mechanisms remain unclear and the therapeutic targets unknown. To study these mechanisms, an ancillary study will be proposed to patient whom accepted to participate in the main project research. The general objective of the ancillary study is to identify early markers of cardiac damage during ischemic stroke having benefited from mechanical recanalization by thrombectomy, and to improve the understanding of the pathophysiology at the origin of cardiac complications in the course of an ischemic stroke with the final objective of identifying new therapeutic targets.

Outcome Measures

Primary Outcomes (1)

  • Specific primary endpoint will be established for each sub-study based on data from the HIBISCUS-Stroke II cohort such as the Rankin score at 3 months.

    This study will allow the realization of various research exploiting the data collected. Each study will defined its relevant primary endpoint. The primary endpoint will most often be the Modified Rankin Scale (mRS from 0 to 6 where 6 is the worst outcome) at 3 months or the vital status at 3 months.

    At month 3

Secondary Outcomes (10)

  • Population description (Age, sex, risk factors, comorbidity, etc.)

    At day 5 (± 2 days) after une initial hospitalization

  • Recanalization efficacy

    During the procedure (endovascular treatment)

  • Long-term hemorrhagic onset

    Day 1 after une initial hospitalization

  • Degree of disability (mRS Score)

    Up to 1 year

  • Quality of life (EQ5D questionnaire)

    At 3, 12 months

  • +5 more secondary outcomes

Study Arms (2)

Cohort group

OTHER

Patient over 18 with an ischemic stroke

Other: Collection of blood samples and MRI imaging in order to create a bio- and imaging-collection

Ancillary study group

EXPERIMENTAL

Patient over 18 with an ischemic stroke

Other: Cardiac MRI with gadolinium injection - Ancillary Study

Interventions

No intervention. Collection of blood samples and MRI imaging in order to create a bio- and imaging-collection

Cohort group

Collection of blood samples and MRI imaging in order to create a bio- and imaging-collection. 100 patients are expected in this group, for each of them, specific cardiac MRI with gadolinium injection will be done at day 6. Moreover, those 100 patients will follow the same visit schedule as the patients in the cohort group.

Ancillary study group
