Macrovascular disease to atherosclerosis. Atherosclerosis is a form of arteriosclerosis (thickening and hardening of arterial walls), characterized by plaque deposits of lipids, fibrous connective tissue, calcium, and other blood substances.

Macrovascular disease is associated with the development of coronary artery disease, peripheral vascular disease, brain attack (stroke), and increased risk of infection. Type 2 diabetes is more closely associated with macrovascular diseases than type 1 diabetes. Peripheral vascular disease and increased risk of infection have important implications in the care of the acutely ill patient. Macrovascular disease Macrovascular disease is a
