Involvement of Matrix Metalloproteinase 9 in Vertebral Arterial Dissection With Posterior Circulation Ischemic Stroke.

ABSTRACT: Background Spontaneous vertebral arterial dissection (VAD) is an important cause of posterior circulation ischemic stroke (PCS), but its pathogenesis remains elusive. Matrix metalloproteinase 9 (MMP-9) is a gelatinase involved in inflammation process and several vascular diseases, such as aorta dissection, but its role in VBD is unclear yet. The present study aimed to determine the association between serum MMP-9 level and VAD-related PCS. Methods and Results We recruited 149 patients with PCS, of which 30 were VAD and 119 had other determined etiologies (non-VAD), and 219 non-stroke individuals. Serum MMP-9 was measured within 14 days from stroke onset. The age of VAD group was 59.6±15.0 years, which is similar to non-stroke group (P=0.510) but significantly younger than non-VAD gr
