MICROANATOMY

Detailed explanation-1: -CAD happens when coronary arteries struggle to supply the heart with enough blood, oxygen and nutrients. Cholesterol deposits, or plaques, are almost always to blame. These buildups narrow your arteries, decreasing blood flow to your heart. This can cause chest pain, shortness of breath or even a heart attack.

Detailed explanation-2: -Peripheral artery disease, also called peripheral arterial disease, is a common circulatory problem where narrowed arteries reduce blood flow to your limbs.

Detailed explanation-3: -Atherosclerosis is where your arteries become narrowed, making it difficult for blood to flow through them. It increases your risk of heart attack and stroke.

Detailed explanation-4: -Coronary artery disease is often caused by cholesterol, a waxy substance that builds up inside the lining of the coronary arteries forming plaque. This buildup can partially or totally block blood flow in the large arteries of the heart.
