Carotid atherosclerosis (AS) is one of the main risk factors for ischemic stroke. Our aim is to evaluate the nontraditional biochemical markers in asymptomatic and symptomatic patients with carotid artery plaque. This study was conducted on 55 patients: 43 with symptomatic and 12 with asymptomatic carotid artery disease. Lipoprotein (a) (Lp(a)), homocysteine, adiponectin, nitric oxide (NO), and tumor necrosis factor alpha (TNF-alpha) levels were measured in the plasma. The mean of total cholesterol, triglyceride, and homocysteine levels was significantly elevated in the symptomatic group as compared with the asymptomatic group (P = .03). In the asymptomatic group, adiponectin and NO levels showed elevations as compared with the symptomatic group but this increase was not significant (P > .05). Lipoprotein (a) and TNF-alpha levels acted inversely with adiponectin and NO. There was an insignificant decline in Lp(a) and TNF-alpha levels in the asymptomatic group as compared with the symptomatic group (P > .05).
