Why would a patient in renal failure get decreased cardiac function?

Why would a patient in renal failure get decreased cardiac function?

Other way around: Usually it is the decreased cardiac function that leads to kidney failure due to lack of blood flow. However, the two illnesses in general share many contributing factors like high blood pressure and diabetes. ...Read more

Kidney Failure (Definition)

The kidneys do several tasks. Dialysis is necessary when one or more of the following occur, that can't be remedied or palliated with medications: 1. Insufficient clearance of daily toxins in food and metabolic waste 2. Insufficient clearance of excess water 3. Dangerous electrolyte imbalance, ...Read more

Why would a patient in renal failure get decreased cardiac output?

Why would a patient in renal failure get decreased cardiac output?

Complex: Even though the mechanisms are complex, one way to understand is that if you lose the ability to filter your blood and eliminate extra fluid from your body (one of the kidney's main functions) your heart will be burdened with pumping a lot more blood than it was intended to do and will therefore fatigue and not pump as well (same as any other muscle would if forced to work "overtime"). ...Read more

Can a person survive prerenal acute renal failure due to severe dehydration without medical help? If so, what are the consequences of not gettin help?

Not advised: Yes, but just because something can be done means that it should be down. A prolonged prerenal state can lead to severe tubular necrosis which is not quickly or always 100% reversible. Prolonged renal failure (prerenal or otherwise) if severe enough puts the individual at risk of death from chemical abnormalities and uremia. Short term risk death, if survives long term risk incomplete recovery. ...Read more

When someone has end stage renal failure, how long can they typically be expected to live if they do not get dialysis or transplant? 92 y/o with chf.

Hard to do: CHF and impaired renal function are difficult to deal with, because improving one makes the other worse. It is a fine line between reducing fluid to help the heart failure, but keeping enough to keep the kidney function from getting worse. Dialysis may be the best answer. See his nephrologist for an answer. ...Read more

Pre-renal acute renal failure may occur without systemic hypotension in patients taking nsaid or acei , why ? I just do not get it ?

Pre-renal acute renal failure may occur without systemic hypotension in patients taking nsaid or acei  , why ? I just do not get it ?

Effect blood flow: Nsaids interfere with prostaglandin production in the kidney , some of which may cause blood vessels to dilate. Blocking the prostaglandin production causes the vessels to constrict and decreases blood flow to the kidney. Acei inhibit angiotensin ii production this allows the efferent arteriole to dilate, lowering the hydrostatic pressure in the glomerulous and decreasing kidney function. ...Read more

How serious is renal failure?

It depends: Usually it depends on the reason , the severity and person health. While renal failure due to dehydration and obstruction ( stones, prostate in a man)is reversible most of the the time , renal failure due to intrinsic kidney problems is sometimes hard to treat. ...Read more

End stage renal failure, what to do?

End stage renal failure, what to do?

ESRD options: Patients with esrd have 4 options. One is hemodialysis (h), either at a dialysis center, doing regular or nocturnal h, or doing h at home. The second is, peritoneal dialysis. Esrd patients can receive a transplant for either a living related or a cadaveric donor. The 4th option is one that very few patients consider, and that is not starting dialysis at all leading to a fatal outcome. ...Read more

What are the causes of renal failure?

What are the causes of renal failure?

Multiple causes: I concur with dr. Griffiths' answer in general. However, one of very common and important cause should be added, namely poorly controlled diabetes. Among the kidney diseases, minimal change lesion is very unlikely to lead to renal failure. ...Read more
