How does atherosclerosis affect the kidneys?

Buildup on kidney (renal) arteries. Fats, cholesterol and other substances (plaque) can build up in and on your kidney artery walls (atherosclerosis). As these deposits get larger, they can harden, reduce blood flow, cause kidney scarring and eventually narrow the artery.

Does atherosclerosis cause CKD?

Chronic kidney disease is associated with an increase in atherosclerotic burden from early stages. Progression of chronic kidney disease is associated with progression of atherosclerosis….Table 1.

Classical Risk Factors	Emerging Risk Factors in CKD
Dyslipidemia	Endothelial dysfunction
Physical inactivity

What is kidney arteriosclerosis?

Renal arteriosclerosis (RA), also known as nephrosclerosis or hypertensive nephrosclerosis, is scarring of the kidney due to infiltration by fibrous connective tissue, usually caused by renovascular diseases or chronic hypertension. The associated vascular changes can potentiate ischemic injury.

How does hyperlipidemia affect the kidneys?

Abnormal cholesterol levels are a hazard to the kidneys, according to the Physicians’ Health Study. This study has been following about 4500 men for 14 years. People with high total cholesterol or reduced HDL (“good”) cholesterol were more likely to have reduced glomerular filtration rate (GFR).

What would happen if atherosclerosis is left untreated?

The complications of atherosclerosis depend on which arteries are blocked. For example: Coronary artery disease. When atherosclerosis narrows the arteries close to your heart, you may develop coronary artery disease, which can cause chest pain (angina), a heart attack or heart failure.

How does CKD accelerate atherosclerosis?

Patients with chronic kidney disease (CKD) are at increased risk of atherosclerotic cardiovascular disease and loss of renal parenchyma accelerates atherosclerosis in animal models. Macrophages are central to atherogenesis because they regulate cholesterol traffic and inflammation in the arterial wall.

How is kidney function related to blood pressure?

Your kidneys play a key role in keeping your blood pressure in a healthy range. Diseased kidneys are less able to help regulate blood pressure. As a result, blood pressure increases. If you have CKD, high blood pressure makes it more likely that your kidney disease will get worse and you will have heart problems.

Can hyperlipidemia cause chronic kidney disease?

Although several factors may explain this association between renal and cardiovascular disease, there is growing evidence that hyperlipidemia contributes not only to cardiovascular disease but also to renal disease progression.

Does kidney disease raise cholesterol?

People with kidney disease have more risk for heart problems. When your kidneys aren’t working well, it also changes the way your body handles cholesterol and other lipids. So, kidney disease and high cholesterol often go together.
