In brief: Usually atheroma

Usually cholesterol based but can also have calcium and fibrous material as well.
Occurs when natural barrier called the endothelium is disrupted allowing these items to infiltrate and eventually block the artey.

In brief: Atherosclerosis

Blockage is the result of worsening atherosclerosis.
This begins when areas of the artery wall thicken due to risk factors like high LDL particle levels, smoking or high blood pressure. Over time, areas of focal thickening may grow into a larger lesion called a “plaque". Stable plaques grow slowly and may limit blood flow over time. Unstable plaques can break causing sudden total vessel blockage.
