Patho physiology of heart failure in anemi?

Patho physiology of heart failure in anemi?

--: Anemia means low oxygen carrying agents in the blood and this is then compounded with the heart effort to maintain the oxygen delivery to other organs especially the brain by increasing its cardiac output -- and in the presence of a weak heart or other stress factor such as trauma or infection, the heart is overwhelmed and congestive heart failure ensues. ...Read more

Non sustained VT<30sec more concern in patients with Left Ventricular Impaired function compared to Normal LV function normal heart ejection fraction?

Non sustained VT<30sec more concern in patients with Left Ventricular Impaired function compared to Normal LV function normal heart ejection fraction?

Yes, but concern: NS Ventricular tachycardia has a higher degree of concern in patients with impaired ejection fraction. However, the larger concern is that having runs of nonsustained VT are not particularly common in the normal population, so even in patients with normal EF, would still be concerned about ischemic heart disease in patients who are having runs of NS VT. ...Read more

Would one papvr with no other abnormalities in the heart lead to right heart failure? My rv enlarged but normal function and, pressure. Lv normal too.

It is possible: You have elevated pulmonary vascular resistance. Though your RV function is normal it is enlarged. You may want to find out why you pulmonary vascular resistance is elevated. Do you have have a condition that is increasing your pulmonary blood flow? Are you having silent pulmonary embolism that is decreasing the size of your pulmonary vascular bed? Both conditions can raise your pulmonary vascular ...Read more

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

Why does a patient in renal failure have decreased cardiac output?

Why does a patient in renal failure have decreased cardiac output?

Not always related: Renal failure in and of itself is not realted to cardiac output, there are many things that can cause both renal failure and decreased cardiac output, but they are not always related. However if someone has really low cardiac output, one could develop renal failure b/c not enough blood is getting to the kidneys. ...Read more

What is significance of small bilateral renal cortical cysts if renal function tests are normal?

What is significance of small bilateral renal cortical cysts if renal function tests are normal?

Not much, but: Need a follow up ultrasound in a few years to see if increasing suggestive of polycystic kidney disease (pkd). If this is the case there is a chance to lose kidney function over long years. It is not a cancer. But increasing cysts number and size can overtake kidneys. Chances are, none of that will happen to you. But, better safe than sorry. Pkd is a benign and slow condition but may cause failure. ...Read more

What does fullness of bilateral renal collecting systems mean?

What does fullness of bilateral renal collecting systems mean?

Renal anatomy: The solid tissue of the kidney is divided into an outer cortex and inner medulla. The blood is filtered and urine and is produced here. Urine is emptied into the collecting system of the renal pelvis. The ureters then transport urine to the bladder. Prominence or enlargement of the collecting system can sometimes indicate obstruction to this outflow. Bilateral means it is seen on both sides. ...Read more

What is the probability of sca with a normal ekg(normal heartbeat, just fast), normal echo shows normal function, normal stress test/normal blood work?

Low: The probability of sca is low in the young, healthy population. Unless you have a family history of sca or a genetic predisposition to sudden death, your risk should also be low. There is a risk calculator that can be applied to assess sca risk in patients undergoing surgery. It was developed by dr. Gupta and can be accessed at www.Qxmd.Com. ...Read more

What is a grossly small stable syrinx in the lower cervical spine? I was told it's part of my normal anatomy but that just doesn't make sense

Like a cyst: A syrinx in the spine is just a small fluid filled sac. It usually does not cause problems if it is stable. Your doctor may want to have it checked again to make sure it is stable, that is not enlarging. If it is truly stable then it is nothing to worry about. If they cause symptoms or enlarged they can be drained but it is best to leave them alone if they are causing no problems. ...Read more

With normal anatomy does their upper palate touches the lower palate uptill epiglottis when their mouth is closed? Pls pls send the reply yes or no.

Throat anatomy: I'm afraid it's not a simple yes or no answer. There isn't a lower palate and an upper palate. There's a hard palate and a soft palate. Neither of them touches the epiglottis when the mouth is closed. The soft palate descends into the throat from the back of the hard palate, and lays behind the tongue when the mouth is closed and during breathing and swallowing. The epiglottis is much lower down. ...Read more

Can you still have renal failure if your creatine bun and urinalysis are normal?

Can you still have renal failure if your creatine bun and urinalysis are normal?

More information..: Usually in renal failure BUN and creatinine, especially creatinine are elevated. If they are normal as well as your GFR which defines how your kidneys are filtering waste products from your blood then there is no renal failure. However, if there is protein in your urine and no infection and if in significant amounts this would need to be checked for kidney damage. We would need to know about this. ...Read more

If someone has complete or close to complete renal failure. Wouldn't the specific gravity in urinalysis be 1.000 or lower than normal consistently since the kidneys can't concentrate anything?

If someone has complete or close to complete renal failure. Wouldn't the specific gravity in urinalysis be 1.000 or lower than normal consistently since the kidneys can't concentrate anything?

Let's think: You're on the right track, but the specific gravity of the glomerular filtrate is 1.010 because of the abundance of ions and other substances. As the tubules fail (glomerular failure is a different matter), the specific gravity tends to settle around a constant 1.010. ...Read more

Isn't it impossible for someone to have end stage renal failure with consistently normal bun and creatine blood levels and only protien in urine?

Isn't it impossible for someone to have end stage renal failure with consistently normal bun and creatine blood levels and only protien in urine?

Most likely yes: The diagnosis depends on multiple factors including the likelihood of improvement with treatment. If there can be no improvement and there is severe protienuria due to glomerular malfunction, it is possible to be labeled end-stage before a significant change in creatinine or BUN has occurred. ...Read more

Acute renal failure after hysterectomy becuase of uterine cancer. Is this normal after a hysterectomy? Problems after surgery, dec 2011, mother 62, now renal failure. Kidney doctor found blockage causing the kidneys to fail.

Acute renal failure after hysterectomy becuase of uterine cancer. Is this normal after a hysterectomy? Problems after surgery, dec 2011, mother 62, now renal failure. Kidney doctor found blockage causing the kidneys to fail.

Assuming : Assuming that your mother did not have chronic renal disease going into surgery, then the prognosis for recovery of kidney function will depend on the reason for the acute injury. Most often acute renal failure is due to a period of low blood pressure, where there is not enough blood pressure to perfuse the kidney which results in something called acute tubular necrosis. There are varying degrees of this, which should improve once the blood pressure stabilizes, in some cases, hemodialysis may be necessary to support the kidney until this recovers. Another potential cause though, particularly in uterine surgery, is injury to the ureters, sometimes due to the extent of the tumor or difficulty in removing the uterus. As you mention that the kidney doctor said a blockage was found, this may be a contributing factor, but usually is known prior to surgery. Other causes (unlikely here) may relate to drug toxicities, for example antibiotics or chemotherapy related. In general, if the patient goes into surgery with good kidney function, the prognosis for recovery is good once all the inciting factors are removed. ...Read more

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
