Soluble ICAM-1: A marker of vascular inflammation and lifestyle

The circulating form of a membrane-bound intercellular adhesion molecule-1 (ICAM-1), has been the source of recent debate as a candidate marker of vascular inflammation in atherosclerosis and myocardial infarction, although its increased levels were also observed in other diseases affecting the cardiovascular system, such as myocarditis, inflammatory cardiomyopathy and heart failure per se. Faulty dietary habits, a sedentary mode of life, smoking, and alcohol abuse, are factors which at least in part contribute to atherosclerosis. This paper describes the responses of sICAM-1 levels to nutrients, physical activity, smoke exposure and alcohol consumption.
