Abstract
|
|
|
Early detection of risk factors related with atherosclerosis, is necessary to decrease the morbidity and mortality of
cardiovasular disease(CVD). Carotid intima-media thickness (IMT) is regarded as a surrogate markers of cardiovascular
risk, believed to detect high risk better than traditional risk factors alone have been proposed. There were numerous
studies which were evaluated the correlation with carotid IMT and cardiovascular events. In addition, measure of carotid
IMT is safe, noninvasive, and relatively inexpensive method to detect early changes of atherosclerosis. Recently, the
method which could measure carotid intima and media thickness seperatly, was developed . In this issue, Won et al,
reported that in hypertensive patients, media thickness was greater than that of normotensive patients. however, intima
thickness was not different in between two groups. They concluded medial hypertrophy contribute to increase IMT in
hypertensive patients. However, there are technical limitation related with the characteristics of ultrasound., individual
measurement of intima and media is very promising method to evaluate the disease progression earlier than the other
methods. Thus this method can be applied to identify and track the progression of atherosclerotic disease. (Korean J Med
