Final answer:
If not treated, atherosclerosis of the renal artery can lead to very high blood pressure (hypertension). Atherosclerosis is the build-up of plaque in arterial walls, causing arteries to harden, and it can lead to severe complications if left untreated.
Step-by-step explanation:
If atherosclerosis of the renal artery is not treated effectively, it can lead to very high blood pressure, also known as hypertension. This condition is a result of the narrowing of the arteries, causing the heart to work harder to pump blood. When the kidneys' arteries are affected, they are unable to perform their role in regulating the body's blood pressure appropriately.
Atherosclerosis is a specific form of arteriosclerosis, characterized by the build-up of plaque in the arterial walls, leading to the hardening of the arteries. This disease progresses slowly and often starts early in life.
Untreated hypertension can result in various complications, including heart attack, stroke, heart and kidney failure, and blindness, which makes it a serious cardiovascular disorder. Therefore, the effective treatment of atherosclerosis is crucial to prevent such complications.
