I70-I79: Diseases of arteries, arterioles and capillaries
Diseases of arteries, arterioles, and capillaries are a group of conditions that affect the small and large blood vessels of your body. These diseases typically occur when these blood vessels become narrow, blocked, or weakened. Sometimes, they may even rupture, which could lead to life-threatening situations. The most common causes are atherosclerosis (buildup of fatty deposits on the arterial walls) and hypertension (high blood pressure). Symptoms may vary greatly depending on the exact disease and the body part affected, but often include pain, weakness, and changes in skin color or temperature. If left untreated, these diseases may progress to serious health problems such as heart attack, stroke, kidney failure, or lower limb amputation. The diseases are usually managed but not cured, with lifestyle changes, medications, and sometimes surgery.
