Basic mechanisms in intracranial large-artery atherosclerosis: advances and challenges.
Intracranial large-artery atherosclerosis is a major cause of ischemic stroke worldwide. Patients affected by this disease are at a high risk of suffering recurrent ischemic events despite antithrombotic therapy. Progression and a greater extent of intracranial atherosclerosis imply a higher risk for recurrence. Studies performed by our group in patients with symptomatic intracranial large-artery atherosclerosis have shown that: (1) C-reactive protein predicts its progression and recurrence, suggesting that inflammation may play a deleterious role in this condition; (2) a high level of the anti-angiogenic endostatin is also associated with a progressive and recurrent intracranial atherosclerosis, which might support a beneficial role for angiogenesis in this group of patients; and (3) elevated lipoprotein(a) concentration and diabetes mellitus characterize those patients with a higher number of intracranial stenoses.
