Background Although the impact of hypertension on carotid intima-media thickness (IMT) and plaques has been well established, its association with femoral IMT and plaques has not been extensively examined. Ultrasonography was applied to assess the AS, including thickened IMT (TIMT) and plaque in the carotid and femoral arteries.

However, most adults will start to develop advanced plaque in their coronary arteries early in life. By age 66, more than half of all females will have evidence of advanced plaque in their coronary arteries, as seen on a CT calcium score. Coronary atherosclerosis, as evidenced by an abnormal CAC score, is a measure of advanced plaque.

Share Let’s first state our goal when we are in the business of ‘Heart Disease Prevention’: To delay the onset of coronary artery disease (atherosclerosis/plaque) that might rupture and cause a heart attack. And the less plaque you have, the lower the risk of a heart attack. And it’s also WAY more common.

To prove there is no plaque rupture, you need to do intravascular ultrasound (IVUS). An angiogram is a "lumenogram;" most plaque is EXTRALUMINAL!! One of the most common is rupture of a non-obstructive plaque, with thrombus formation and OMI that spontaneously lyses and leaves a wide open artery. It can only be seen by IVUS.
