what is the relationship between heart failure and renal failure?

Relatively recent research has shown that heart failure is a significant risk factor for kidney disease. When the heart is no longer pumping efficiently it becomes congested with blood, causing pressure to build up in the main vein connected to the kidneys and leading to congestion of blood in the kidneys, too.

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.

Chronic kidney failure is a condition where the kidneys' ability to filter waste from the bloodstream becomes worse over time, generally over a period of years. Acute kidney failure is the sudden loss of this important ability. If your kidneys have experienced a direct injury or an obstruction, you are at risk.

If the damage continues, your kidneys could fail. In fact, diabetes is the most common cause of kidney failure in the United States. People with kidney failure need either dialysis or a kidney transplant. You can slow down kidney damage or keep it from getting worse.

If left untreated, CKD can progress to kidney failure and early cardiovascular disease. When the kidneys stop working, dialysis or kidney transplant is needed for survival. Kidney failure treated with dialysis or kidney transplant is called end-stage renal disease (ESRD). Learn more about ESRD.

Chronic kidney disease (CKD) and cancer are connected in a number of ways in both directions: cancer can cause CKD either directly or indirectly through the adverse effects of therapies; CKD may, conversely, be a risk factor for cancer; and both may be associated because they share common risk factors, often toxins.

If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure.

Chronic kidney disease may be caused by diabetes, high blood pressure and other disorders. Early detection and treatment can often keep chronic kidney disease from getting worse. When kidney disease progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life.

When the kidneys are no longer working effectively, waste products, electrolytes, and fluid build-up in the blood. Dialysis takes over a portion of the function of the failing kidneys to remove the fluid and waste products. Kidney transplantation can even more completely take over the function of the failing kidneys.

If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks.

When you have kidney disease, your kidneys cannot make enough EPO. Low EPO levels cause your red blood cell count to drop and anemia to develop. Most people with kidney disease will develop anemia. Anemia can happen early in the course of kidney disease and grow worse as kidneys fail and can no longer make EPO.

End stage renal disease (ESRD), or renal failure, is the end stage of kidney function—not the end stage of life. Also called stage 5 of CKD, ESRD indicates that both kidneys are no longer working sufficiently to keep your body healthy and chemically balanced.

Kidney disease usually affects both kidneys. If the kidneys' ability to filter the blood is seriously damaged by disease, wastes and excess fluid may build up in the body.

It also means that you may be at risk for complications of kidney failure. Some of the most common complications of kidney failure include anemia, bone disease, heart disease, high potassium and fluid buildup.

Weight gain. It's very common for people with heart failure to experience rapid changes in their weight. If your heart failure is causing fluid accumulation, you will gain weight. However, if your body loses this fluid (for example, after appropriate treatment), you will lose weight.

High blood pressure is the second most common cause of ESRD. Other problems that can cause kidney failure include: Autoimmune diseases, such as lupus and IgA nephropathy. Genetic diseases (diseases you are born with), such as polycystic kidney disease.

Kidney problems can develop suddenly (acute) or over the long term (chronic). Many conditions, diseases, and medicines can create situations that lead to acute and chronic kidney problems. Acute kidney injury, which used to be called acute renal failure, is more commonly reversible than chronic kidney failure.
