Arterial stiffness was independently associated with deep or infratentorial CMBs but not lobar CMBs. These findings suggest a pathophysiological association between arterial stiffness and CMBs in the deep or infratentorial region.

Increased frequency of concomitant PCSE and that of the atherothrombotic mechanism may explain the high risk of stroke in patients with higher CHADS(2) /CHA(2) DS(2) -VASc score.

Considering the positive association between the presence of CMBs and OA-related ICH, our results suggest that the increase in ICH in high-risk groups during OA may be related to an increased burden of CMBs.

Patients with low ABI values presented with more severe ischaemic stroke. Contribution of pre-existing PAD to leg weakness may play a role in the initial severity of stroke in patients with PAD. Our findings suggest that poor clinical outcomes in patients with PAD may be partially explained by their increased likelihood for severe stroke.
