PRIMARY outcome

Timeframe: Twelve months after randomization.

Population: Full analysis set

Presence of other cerebro-cardiovascular morbidity or mortality assessed by aggravation of patient status (modified Rankin Scale). The modified Rankin Scale is ranging from 0 to 5. The higher scale indicates the worse outcome.

SECONDARY outcome

Timeframe: At randomization and twelve months after randomization.

The changes of white matter hyperintensities, assessed by the Fazekas scale using brain magnetic resonance imaging. The Fazekas scale is a 4 point white matter disease severity scale with values ranging from 0 to 3. It quantifies the amount of white matter T2 hyperintense lesions each in periventricular white matter and deep white matter. Higher scales mean a worse white matter status. In the region of the periventricular white matter, 0 means absence of the lesion; 1, caps or pencil-thin lining lesion; 2, smooth halo lesion; 3, irregular high intense signal extending into the deep shite matter. In the region of the deep white matter, 0 means absence of the lesion; 1, punctate foci lesions; 2, beginning confluence; 3, large confluent hyperintense areas.
