Atherosclerosis
-
High serum concentrations of l-arginine and l-homoarginine increase nitric oxide (NO) availability and thereby improve endothelial function. Information about the association of these markers with peripheral arterial disease (PAD) and related outcomes is sparse. ⋯ This study in male patients with intermittent claudication and age- and diabetes-matched controls showed an association of l-homoarginine and l-arginine with PAD. During follow-up, l-arginine was associated with incident cardiovascular events probably due to its primary role in NO metabolism and impact on endothelial integrity. l-homoarginine was related to all-cause mortality implying a broader role in metabolic processes besides endothelial function.

Multicenter Study Comparative Study
The association of nonalcoholic fatty liver disease, obesity, and metabolic syndrome, with systemic inflammation and subclinical atherosclerosis: the Multi-Ethnic Study of Atherosclerosis (MESA).
We characterized the association of 3 metabolic conditions - obesity, metabolic syndrome, and nonalcoholic fatty liver disease (NAFLD) - with increased inflammation and subclinical atherosclerosis. ⋯ NAFLD is associated with increased inflammation and CAC independent of traditional risk factors, obesity and metabolic syndrome. There is a graded association between obesity, metabolic syndrome, and NAFLD with inflammation and CAC.
