The kidneys manufacture a hormone called erythropoietin , which tells the bone marrow to make more red blood cells. If your kidneys are damaged, your erythropoietin levels can fall, and your body will not make enough red blood cells. Several studies have shown that anemia can be related to cardiovascular disease. Red blood cells contain a protein called hemoglobin, which helps transport oxygen throughout the body.

If a body is not getting enough oxygen, the heart is not getting enough oxygen either.

Without adequate oxygen to the heart muscles, a person may be susceptible to a heart attack. Anemia can also cause the heart to pump more blood in order to circulate enough oxygen throughout the body.

Heart failure - what is it?

As the heart works harder, the muscle in the left lower chamber of the heart can develop thick walls. This is a condition called left ventricular hypertrophy LVH.

LVH can increase the chance of heart failure. High blood pressure: The kidneys make renin, which is an enzyme that helps control blood pressure. When blood pressure is too low, healthy kidneys release renin to stimulate different hormones that increase blood pressure. Damaged kidneys may release too much renin, which can lead to high blood pressure. High blood pressure increases the risk of heart attack, congestive heart failure and stroke. High homocysteine levels : Homocysteine is an amino acid normally found in blood. Healthy kidneys regulate the amount of homocysteine in the blood and remove any excess.

But damaged kidneys cannot remove the extra homocysteine.

Introduction

High levels of homocysteine have been linked to the build up of plaque in the blood vessels, which can lead to cardiovascular diseases such as atherosclerosis when fatty material deposited along the artery walls gets hard and blocks the blood flow and coronary artery disease. High levels of homocysteine may also damage the lining of the blood vessels, making a person prone to blood clots which increase the risk of stroke and heart attack. Calcium-phosphate levels : Different studies have suggested a link between the calcium and phosphorus levels in patients undergoing dialysis and the hardening of the coronary arteries.

Healthy kidneys help keep calcium and phosphorus levels in balance. But damaged kidneys cannot do this.

Often, there is too much phosphorus and calcium in the blood. When this happens, there is a risk for coronary artery disease. Diabetes and high blood pressure are the two leading causes of kidney disease.

Here is how each can affect your heart and lead to cardiovascular disease:. Diabetes : Diabetes is a condition where excess sugar remains in the bloodstream. This sugar can damage the blood vessels not only in the kidneys but elsewhere in the body, including the major blood vessels that feed the muscles of the heart. High blood pressure : Not only is high blood pressure a complication from diabetes, it is also a cause of kidney disease.

Too much pressure can weaken the walls of the blood vessels, which can lead to a stroke. Whether your cardiovascular disease is caused by complications of your kidney disease or by the underlying cause of your kidney disease, it's important to be aware of the impact it can have on your overall health.

Treating the cause of your cardiovascular disease and keeping other conditions like chronic kidney disease, diabetes and high blood pressure under control will help you feel better. Your kidney doctor will monitor the health of your kidneys and check for signs of cardiovascular disease. You will also be monitored for complications like anemia and high blood pressure.

Part of your treatment program may include taking certain medications to treat these complications, as well as treating any calcium or phosphorus imbalances in the body.

Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden. These damaged arteries are not able to deliver enough blood to the kidney tissue. The nephrons in the kidneys are supplied with a dense network of blood vessels, and high volumes of blood flow through them.

Kidney failure due to high blood pressure is a cumulative process that can take years to develop. But, you can limit your risk by managing your blood pressure. Can HBP cause kidney failure?
