Abstract
Background Branch atheromatous disease (BAD) is one of the stroke subtypes caused by occlusion at the origin of a deep penetrating artery of the brain and is associated with a microatheroma or a junctional plaque. Patients with BAD often develop progressive worsening of neurologic deficits, although these patients often present minor stroke with clinical characteristics of lacunar syndrome at the onset. Pentraxin 3 (PTX3) is known to be a key molecule involved in the pathogenesis of atherosclerosis. Although a high level of serum PTX3 is observed in patients with acute coronary syndrome, there are no reports on PTX3 levels in patients with BAD. This study aimed to investigate whether serum PTX3 levels can distinguish BAD from other stroke subtypes. Methods We investigated 93 patients with ischemic stroke. Serum PTX3 levels on admission were measured using enzyme‐linked immunosorbent assay in patients with BAD and those of other stroke subtypes (each n ≥ 20). Results The median PTX3 levels in patients with BAD (4840 pg/mL) were higher than those with other subtypes of stroke (3397 pg/mL in lacunar stroke, 1298 pg/mL in large artery atherosclerosis, 1470 pg/mL in cardioaortic embolism, and 1006 pg/mL in control) (all p < 0.01). Conclusion Our results suggest that elevated serum pentraxin 3 levels might predict the diagnosis of BAD at a very early stage.Funding Information
