Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Efficacy objectives are: • Assessment of incidence of microembolic signals (MES) by transcranial Doppler (TCD) examination (before and after treatment) • Rate of MES per hour (before and after treatment) • Cerebral lesion analysis by DWI-NMR • Assessment of neurological status (NIH Stroke Scale) • Clinical endpoints will be summarised cumulatively i.e. before treatment, after treatment, at 3 months and at 12 months. The following endpoints will be recorded: o Rate of all cause death o Rate of stroke-related death o Any TIA, amaurosis fugax or stroke including haemorrhagic stroke • Assessment of cardiovascular outcome including myocardial infarction and re-intervention up to 3 and 12 months ;Secondary Objective: Not applicable;Primary end point(s): Exploratory endpoints are: • Assessment of incidence of microembolic signals (MES) by transcranial Doppler (TCD) examination (before and after treatment) • Rate of MES per hour (before and after treatment) • Cerebral lesion analysis by DWI-NMR • Assessment of neurological status (NIH Stroke Scale) • Clinical endpoints will be summarised cumulatively i.e. before treatment, after treatment, at 3 months and at 12 months. The following endpoints will be recorded: o Rate of all cause death o Rate of stroke-related death o Any TIA, amaurosis fugax or stroke including haemorrhagic stroke • Assessment of cardiovascular outcome including myocardial infarction and re-intervention up to 3 and 12 months ;Timepoint(s) of evaluation of this end point: Baseline to 1-2 days after treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): •Rate of MES per hour (before and after treatment) •Assessment of neurological status (NIH Stroke Scale) •Cerebral lesion analysis by DWI-NMR and correlation to neurological status (before and after treatment) •Clinical endpoints will be summarised cumulatively i.e. before treatment, 1 and 3 days after treatment, at 3 months and at 12 months. The following endpoints will be recorded: oRate of all cause death oRate of stroke-related death oAny TIA, amaurosis fugax or stroke including haemorrhagic stroke •Assessment of cardiovascular outcome including myocardial infarction and re-intervention up to 3 and 12 months ;Timepoint(s) of evaluation of this end point: Baseline to 3 months / 12 months. | — |
