Coronary Artery Disease
Coronary Artery Disease (CAD) is caused by a build-up of fatty substances like cholesterol. Where they collect in the artery, the internal lining thickens, the
artery narrows, and blood flow slows. These fatty build-ups are sometimes called plaque or lesions.
If the plaque narrows the channel of the artery or lumen, it may make it difficult for adequate quantities of blood to flow to the heart muscle. If the build-up reduces flow only mildly, there may be no noticeable symptoms at rest, but symptoms such as chest pressure may occur with increased activity or stress. These are signals that your heart is having difficulty.
