Incidence of kidney damage associated with coronary artery bypass surgery
has increased significantly
Excerpts:
The incidence of kidney damage associated with coronary artery bypass
surgery has increased significantly over the past 16 years in the United
States, but the rate of death from such damage has decreased significantly
during the period, according to a new analysis.
In their analysis of more than 5 million discharges from hospitals across
the United States, the researchers at Duke University Medical Center found
that the incidence of acute renal failure associated with coronary artery
bypass surgery increased almost five-fold during the study period. The
researchers estimate that approximately 20,000 cases of the disorder occur
nationwide each year.
The rate of death from acute renal failure caused by bypass surgery dropped
almost three-fold during the study period, the researchers said. Still,
patients with the disorder tend to have higher death rates, and also to
require longer hospital stays, than patients who do not experience kidney
damage after surgery.
The findings suggest that current strategies used to prevent acute renal
failure following bypass surgery may not be as effective as previously
thought, the researchers said.
More than 467,000 bypass procedures are performed each year in the United
States.
Most cases of kidney injury after bypass surgery are transient and cause no
serious damage, according to Madhav Swaminathan, M.D., an anesthesiologist
and senior member of the study team. But up to 2 percent of affected
patients will require kidney dialysis, and 60 percent of those patients will
die before hospital discharge, he said.
On average, bypass patients without complications spend about five days in
the hospital, while patients with acute renal may spend 20 days, Swaminathan
said.
How bypass surgery causes kidney damage is not exactly known, the
researchers said, but several possible culprits have been suggested. Damage
may be caused by alterations in blood flow that occur as a result of being
placed on a heart-lung machine during surgery, or damage may occur when tiny
bits of plaque break off of the walls of blood vessels, travel to the
kidneys, and block its tiny blood vessels.
Drugs used during the coronary artery bypass surgery also may also
contribute to the phenomenon, and recent Duke research has hinted at a
genetic susceptibility, the researchers added.
Nor do scientists fully understand the supposed benefits of the various
strategies currently used to protect the kidneys during and after surgery,
Swaminathan said.
"During surgery, we try to maintain hydration in the kidneys and keep them
flushed," he said. "After surgery, we adjust medication dosages to the level
of changing kidney function.
But, he added, there have been few randomized trials conducted testing drugs
to protect the kidneys. However, Swaminathan said, no single strategy or
drug has proved superior to standard therapy in reducing the incidence of
renal dysfunction after cardiac surgery.

So, in summary, more people are staying alive because they get
bypasses and one of the unfortunate apparent side-effects is resulting
in fewer deaths as well.
If you ever need a bypass, Jan, don't forget to tell the doctor to
leave the blocked arteries right where they are because you don't want
to be one of the people who live a longer, more satisfying life
following the surgery.

The problem is the ever increasing incidence of the following two
things that damage kidneys years before the bypass surgery:
(1) Type-2 Diabetes.
(2) Prior history of angioplasty with stenting.

While the information resulting from several patients may be called data, it

Robert W. Maver, F.S.A., M.A.A.A.
Reprinted from The World Research News, 1st quarter 1998 issue, with
permission.
The premise is that there are innovative medical therapies existing
today that offer solutions to some of our most pressing health
problems and that at the same time offer a significant reduction in
health care costs. These therapies are largely being ignored or in
some cases ridiculed.
To most of us involved in scientific research, this seems an odd
notion at first. Surely, one would think, discoveries and
breakthroughs offering great promise in the treatment of disease
would be at once communicated and embraced by the scientific/medical
community. However, those who study the history of scientific
progress conclude otherwise. Science frequently fails to demonstrate
the dispassion we attribute to it.
Historical citations of science resisting new ideas are too numerous
to review in any depth, from Copernicus to Galileo to Darwin, Mendel,
Ohm, Young, Pasteur, lister, Fleming ... the list goes on and on. It
is perhaps more instructive to briefly examine the reasons for resis
tance to innovation in medicine.
Tomato Effect - The tomato effect in medicine occurs when a highly
efficacious therapy for a certain disease is ignored or rejected
because it does not '.make sense" in the light of accepted theories
of disease mechanism and drug action. Doctors at the University of
New Mexico School of Medicine introduced the tomato effect in JAMA.
May 11, 1984. Its name is derived from the history of the tomato in
North America. By 1560, the tomato was becoming a staple of the
continental European diet. However, it was shunned in America until
the 1800's. Why? Because we knew it was poisonous. Everyone knew
tomatoes belong to the nightshade family. The leaves and fruit of
several plants in this family can cause death if ingested. The fact
that Europeans were eating tomatoes without harm was not relevant. It
simply did not make sense to eat poisonous food.
Peer Review - Ile peer review process probably has done more to
discourage innovative research than any other factor that I have
observed. The March 9, 1990 issue of JAMA was devoted entirely to the
topic of peer review. One article in particular, by Horrobin (himself
editor of a peer reviewed medical journal) , cited 18 examples of
peer review attempting to suppress medical innovation. The article
observed: " ... some of the most distinguished of scientists may
display sophisticated behavior that can only be described as
pathological. Editors must be conscious that, despite public
protestations to the contrary, many scientistreviewers are against
innovation unless it is their innovation. Innovation from others may
be a threat because it diminishes the importance of the scientist's
own work.
"Peer review in the grant giving process is so restrictive that most
innovative scientists know they would never receive funding if they
actually said what they were going to do. Scientists therefore have
to tell lies in their grant applications. Such views have explicitly
been stated by at least two Nobel Laureates."
The (JAMA) article contends that medicine has lost sight of the basic
purpose of peer review, asserting, "the true aim of peer review in
biomedical science must be to improve the quality of patient care."
Wrong Economics - When a new therapy comes along that is cheaper,
safer and more effective, it is seen as a competitive threat to those
engaged in the therapy it will displace. Those who stand to be most
economically disadvantaged naturally endeavor to block its
acceptance.
International Barriers - A combination of communication problems
(language barriers) and national chauvinism (if it wasn't discovered
here it can't be of much value) keep some innovative practices
developed in Europe and Asia from reaching the United States.
Cumbersome Bureaucracy - It has been estimated that the FDA approval
process takes an average of 12 years and costs $231 million. This
presents unique difficulties for independent researchers and for
therapies that do not lend themselves to patentability.
It is my observation that there is a role for the insurance industry
in advocating evaluation of innovative medical thera pies. Actuaries
should be almost immune to the tomato effect. We are focused almost
exclusively on statistical results as opposed to theory. Since the
insurance industry pays most of the bills, it should have great
economic motivation to see safe., effective and inexpensive therapies
extensively evaluated and widely disseminated. Consideration of an
industry-wide fund for innovative research could deal with the
problem of peer review. The insurance industry is a sleeping economic
giant. When it awakens to the cost containment possibilities
available through innovative therapies, we will see enormous changes
in the practice of medicine.

It has been established years ago that bypass surgery only lengthens life
slightly in 9 years, the average time before the procedure fails. It is
considered a comfort procedure...ie you probably feel better afterwards.
Say, are you always that coherent?

If the procedure is being considered only for alleviating symptoms and
not for extending life, then non-invasive enhanced external
counterpulsation (EECP) should be tried first because it does have a
response rate of around 85% with virtually no risk of serious
periprocedural complications.

Too bad this thread has degenerated so much.
The Subject line caught my eye because my 81-year-old Father-In-Law is going
to have an angioplasty on one coronary artery, and a stent placed in
another, tomorrow.
This procedure will take place in NYC, and I understand that it will either
be taped and shown, or broadcast live to, a medical convention going on down
south somewhere.
I also understand that they will be using a relatively new technology to
cool his kidneys before the procedure is done.
I'm assuming this is being done to lessen the chance of kidney damage
occuring.
Although similar, angioplasty and stent insertion are not bypass and not
open heart surgery. If it weren't for possible problems with the stent in
the first couple days, it would verge on being out-patient.
It is interesting that they are going to keep the kidney temp under control.
I wouldn't know if it's for the same reason described by Chung. What is
known that any invasive technique, for heart or other, leaves some altered
blood (debris) and the kidney's job is to clean.
In an 81 year old it could also just mean a compromised kidney to begin
with.
Actually the biggest danger might be a NYC hospital with a NYC Doctor :>)

Understood.
It was the 'kidney damage' part that interested me the most. As I
understand it, the procedure(s) being done tomorrow will both be done during
the same instance, and through his femoral artery.

Again. I'm sorry for any confusion. And though I do understand that
opening one's femoral artery could be considered "invasive", he's (My F-I-L)
not having bypass surgery.

Yes. That has already been established. His kidneys are beginning to fail,

I'm no Dr. But from what I'm told, my dad has at least one obstruction in
an area of his heart that's a "difficult repair". ANd I believe that's
where the stent will be inserted.

What is interesting to me is tha angioplasty rather than stent in an 81 year
old, not the other way around. They must have thier reasons.
Ok. :-)

Again. I am NO Dr. But as I understand it, there are two different
arteries involved. One which is completely closed (that caused a "silent
heart attack a few months ago) that they are going to attrmpt to re-open via
angioplasty, and the other in which they are aiming to insert the stent that
is about 80% accluded.
And yes. This is being done on an out-patient basis if all goes well. He
will be staying overnight, but barring anything unforseen he will be home on
Thursday.
I'm just really curious about this kidney cooling/re-warming thing.
Thank you for your replies.

That certainly does not describe Chung's experience.
But you are wrong in saying that credible data are a controlled set of
anecdotes. According to Merriam-Webster's Online dictionary, an anecdote is
a usually short narrative of an interesting, amusing, or biographical
incident. Credible data are not just a set of stories.

research paper or article has been examined by a group of experts in the

Incidence of kidney damage associated with coronary artery bypass surgery
has increased significantly
Excerpts:
The incidence of kidney damage associated with coronary artery bypass
surgery has increased significantly over the past 16 years in the United
States, but the rate of death from such damage has decreased significantly
during the period, according to a new analysis.
In their analysis of more than 5 million discharges from hospitals across
the United States, the researchers at Duke University Medical Center found
that the incidence of acute renal failure associated with coronary artery
bypass surgery increased almost five-fold during the study period. The
researchers estimate that approximately 20,000 cases of the disorder occur
nationwide each year.
The rate of death from acute renal failure caused by bypass surgery dropped
almost three-fold during the study period, the researchers said. Still,
patients with the disorder tend to have higher death rates, and also to
require longer hospital stays, than patients who do not experience kidney
damage after surgery.
The findings suggest that current strategies used to prevent acute renal
failure following bypass surgery may not be as effective as previously
thought, the researchers said.
More than 467,000 bypass procedures are performed each year in the United
States.
Most cases of kidney injury after bypass surgery are transient and cause no
serious damage, according to Madhav Swaminathan, M.D., an anesthesiologist
and senior member of the study team. But up to 2 percent of affected
patients will require kidney dialysis, and 60 percent of those patients will
die before hospital discharge, he said.
On average, bypass patients without complications spend about five days in
the hospital, while patients with acute renal may spend 20 days, Swaminathan
said.
How bypass surgery causes kidney damage is not exactly known, the
researchers said, but several possible culprits have been suggested. Damage
may be caused by alterations in blood flow that occur as a result of being
placed on a heart-lung machine during surgery, or damage may occur when tiny
bits of plaque break off of the walls of blood vessels, travel to the
kidneys, and block its tiny blood vessels.
Drugs used during the coronary artery bypass surgery also may also
contribute to the phenomenon, and recent Duke research has hinted at a
genetic susceptibility, the researchers added.
Nor do scientists fully understand the supposed benefits of the various
strategies currently used to protect the kidneys during and after surgery,
Swaminathan said.
"During surgery, we try to maintain hydration in the kidneys and keep them
flushed," he said. "After surgery, we adjust medication dosages to the level
of changing kidney function.
But, he added, there have been few randomized trials conducted testing drugs
to protect the kidneys. However, Swaminathan said, no single strategy or
drug has proved superior to standard therapy in reducing the incidence of
renal dysfunction after cardiac surgery.
Then you can understand that choice to not reflect ability.
For example, though GOD has chosen not take from you HIS generous gift
of free will, know that not only is HE able to take away you free will,

I have and saw similar information before it was posted. The only surprise
was the fact that there is someone who questions it outright with zero
knowledge of the subject.
John 12:40 applies to many here.
Now, rather than continue as an obvious troll, respond with some intelligent
comment on the possible relationship of heart surgery and the increased
incidence of kidney problems. You can't. Trolls never can.
Many thanks, much praise, and all the glory to GOD for compelling you
to remind me of the following from Isaiah 6:
In the year that King Uzziah died, I saw the LORD seated on a throne,
high and exalted, and the train of his robe filled the temple. Above
HIM were seraphs, each with six wings: With two wings they covered
their faces, with two they covered their feet, and with two they were
flying. And they were calling to one another:
"Holy, holy, holy is the LORD Almighty;
the whole earth is full of HIS glory."
At the sound of their voices the doorposts and thresholds shook and the
temple was filled with smoke.
"Woe to me!" I cried. "I am ruined! For I am a man of unclean lips, and
I live among a people of unclean lips, and my eyes have seen the King,
the LORD Almighty."
Then one of the seraphs flew to me with a live coal in his hand, which
he had taken with tongs from the altar. With it he touched my mouth and
said, "See, this has touched your lips; your guilt is taken away and
your sin atoned for."
Then I heard the voice of the Lord saying, "Whom shall I send? And who
will go for US?"
And I said, "Here am I. Send me!"
HE said, "Go and tell this people:
'You will be ever hearing, but never understanding;
you will be ever seeing, but never perceiving.'
This people's heart has become calloused;
they hardly hear with their ears,
and they have closed their eyes
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts,
and turn and be healed."
Then I said, "For how long, O Lord?"
And HE answered:
"Until the cities lie ruined
and without inhabitant,
until the houses are left deserted
and the fields ruined and ravaged,
until the LORD has sent everyone far away
and the land is utterly forsaken.
And though a tenth remains in the land,
it will again be laid waste.
But as the terebinth and oak
leave stumps when they are cut down,
so the holy seed will be the stump in the land."
**** End of Isaiah 6 ****
Amen.
GOD's will be done and not our will.
May GOD continue to heal our hearts with HIS living water, dear brother
Vernon whom I love unconditionally.
Prayerfully in Christ's amazing love,
Andrew <><

Clearly, you're not familiar with the certified quack, looney maroon, and

to scrutiny, because he is delusional and believes that he directly quotes

Your point?
I don't know Chung.
I do respond to subject matter.
It's like stating that a particular race has a higher incidence of sickle
cell anemia or the earth is round and some nut case says "Cite please".
I do know that he posts a lot of words having nothing to do with the subject
and has limited knowledge of the bible, but that has nothing to do with
kidney stress during any major surgery that temporarily limits circulation.
If Chung states that this planet is spherical, ask for a cite. If he says
the sun rose in the east this morning, check.

If he makes any kind of claim on any topic whatsoever, don't take it for
granted that he might know what he's talking about, even if he says
something you can confirm as true. He's crazier'n batshit.
Oh. O.K. it is just a personal vendetta on your part, fine.
He HAPPENED to make a statement (for who knows what reason) that is true.

Oh, hardly. I didn't even know he existed until last summer. No, I just

O.K.
there is NO way to insert a stent than via angioplasty..also....only very
infrequently is either done in any way other than a femerol approach
>
>
>
Duuhhh, It's no longer called angioplasty then.
you must not spend much time in operating rooms...
angioplasty..by definition..is the insertion of a catheter...usually into
the femoral artery...threaded into the coronary arteries...for the purpose
of increasing the luminal size...sorta like a rota rooter does
in MOST if not all instances...a stent is threaded OVER the
catheter..inflated and then left in place to hopefully keep the occluded
area open
I don't know the exact numbers...but ALL stent placements involve doing an
angioplasty
again...do your research...
>
>
Angiography is the study of blood vessels. Catheterization is the process
of inserting catheters. Angioplasty refers to the dilation, typically with
a balloon, of an artery. Stenting refers to the placement of an artificial
stent and need not be at all associated with angioplasty.
I spend plenty of time in and around operating rooms, doctors.
Once the purpose is to no longer blow a balloon but insert a stent it is no
longer called angioplasty.
So, you posted the definition above. Your definition was of angioplasty.
You proved yourself wrong.
Thank you.
Angio - plasti
Catheter with stent, not angio -plasti.
agreed

let me repeat...wrong....
stents are necessarily "associated" with angioplasty...
perhaps a google search will help...try Mayo Clinic...Mass General...etc...
I repeat...a stent cannot be inserted into a coronary vessel that is
occluded...
thus all placement of stents include angioplasty (inflating the balloon at
the end of the catheter)...
so please do explain HOW a stent can be inserted into an occuded vessel??
perhaps what you mean...is that not all plasties involve stents...but the
reverse is never true...
not to mention...angiography is intra vessel xrays using a dye to find such
occlusions...therefore...angiography is also required prior to plasty or
stents...
at least that is the way reputatable intervenational cardiologists do it...
>
>
not sure where you are
it is called "angioplasty with stent"....which most angioplasties are...
>
>
An arterial catheter is used for many purposes.
If a balloon is part of the catheter and inflated, it is called angio PLASTI
If a stent is attached to the end, it is called a stent placement or
emplacement.
Each has advantages and disadvantages. On a patient's record, for the
purposes of follow-up by a non originating Doctor, there would be a major
difference in treatment of sudden angina between recent "angioplasti" and
"stent emplacement".
In medicine as well as all science applications (let's forget about numb
numb daily use), specific use of words and semantics is all important.
Sloppy use results in death too often.
The stent is inserted and then expanded. A totally occluded artery would
require laser treatment. The stent is inserted as a collapsed mesh ( often
smaller then the catheter. When in place, it is expanded, pushing the walls
out, hopefully "Locked" in the out position. Then we hope the body doesn't
try to reject the foreign substance.
It's called stent emplacement or for short "stenting"
Refering to the procedure as angioplasti is misleading, plain and simple,
misleading.
Ah, I see where you're going with this. Yes, you need to open a vessel
prior to stenting it. I thought you were implying that you can't have
angioplasty without stenting. We agree then.
sorry...and yes we agree!!!
don't know where Vernon has been or done....but the USUAL protocol is to
insert the guide wire(which acts as a "rail" so to speak.....
first dye is injected so docs can observe areas of occlusion
if indicated...a balloon is threaded over the wire...it is
inflated...usually several times to squish the plaque against the lumen
walls...the balloon can be moved to other areas if occlusion is noted
elsewhere (not unusual)...
this is not for the faint of heart...balloons can break...pieces of plaque
can break off..chest pain usually worsens during times of balloon
inflation...etc..and worst of all....it is possible for the catheter to
puncture the arterial wall....voila..it is now a surgical emergency
....bottom line..always get an angioplasty (if possible) in a center that
has "open heart surgery backup)....tho nowadays it is not uncommon for
community hospitals to be doing them...this makes me nervous
lastly...again..don't have the stats..but a stent is "deployed " (actually
that is the word!!)...after the area of occlusion is opened...the stent is a
metal mesh scaffolding..very similar to those springy things inside a
ballpoint pen....angioplasty alone has about a 40% incidence of re
stenosis..so the stent can and hopefully does...reduce this reocclusion
rate..since once in there..the metal springie thing cannot be removed...
neither angioplasty nor stenting tho..are cures for the problem of coronary
artery disease...reduction of lipids...lifestyle changes...etc...are
necessary..and if stent...the patient may well be on meds like Plavix to
hopefully keep the clotting problem at the stent to a minimum...
and of course...a daily baby asa is a good thing...
an excellent resource is at www.angioplasty.org
have been thru all of this both personally and professionally...it is
scarey...
in addition of course are the "thrombolytic meds" that can and should be
given as the patient hits the ER door and is diagnosed via EKG with an acute
heart attack...the newer ones literally "melt" the clot away...I was amazed
to watch my hubby's face and pain level change within 10 minutes....we were
so impressed ..and had an RN friend at the drug company who recommended him
for interview and a page in the annual report!!! got us a trip to
SFrancisco
bad news is...he was within the %%% where the angioplasty was not long
lived..and the drug eluting stents were not on the market yet...two years
later he required CABG!!!!!
as we speak he is demo'ing a bathroom....
end of rant...

this is where you are confused...the INITIAL device used on the arterial
catheter..after dye injection has located the area (s) of stenosis is ALWAYS
a tiny balloon.....
the balloon..thus angioplasty...is used to push back the plaque that is
occluding the vessel...

a stent can be threaded OVER the guide wire AFTER the balloon has widened
the occlusion...
the stent..as you described..is then "deployed"....ie...opened up and left
there...it cannot be removed...
again..and for the last time...angioplasty CAN be used without stent
stent cannot NOT be used without plasty first...
at least that is NOT the protocol used in anyplace I know of...
my hubby...who had a major MI...had thromboltics in the ER...next day he had
a plasty...they did NOT implant a stent (drug eluting ones not available in
US at that point....too bad)
two years later his "plasty" had reoccluded ...as do about 40% of non
stented ones...
he had CABG..."beating heart" open heart...yes they "cracked his
chest"...but avoiding use of the heart lung machine reduces the risk of
clots to brain and "pump head" .....not all surgeons are adept at this
method...
he was home in 72 hours...turns 67 next month and is currently demo'ing a
bathroom and volunteering for Habitat...
BTW..he also spent his entire exec career in the cardiovascular
business....pres of an international device manufacturer...and has been in
EVERY major heart operating room in the world...
not bragging....but we knew where to go...what to ask..and got a good
outcome..
and we have it all on a videotape..as he was a "teaching tool" for a major
device company...names to be excluded...
just had to report that I just spent over an hour on the phone with my
hubby...the "device expert" and he cleared up a few things for me...
firstly...once the initial "empty catheter is inserted" ...the dye is
injected to show what is going on...this is called...of course "ANGIOGRAPHY"
once an area of occlusion is identified...the balloon catheter is inserted
(the initial catheter is literally hollow)...balloon catheters come in
different diameters etc...as obviously some coronary arteries are BIG and
others are much smaller...thus one balloon cannot be used in all
areas.....the "average" number of balloon catheters used per procedure is
about 3!!
once the occludded or narrowed area is pushed back...the cardiologist
decides whether or not a stent is indicated (not always..but about 70% of
balloon angios are then stented)....
the "stent" catheter is a different one than the balloon one....tho some
device manufacturer is working on a combo catheter...first a balloon to
inflate the area....then a stent to be deployed and left there (this
actually may already be on the market...hubby has not worked for 6 years)
if more than ONE stent is needed...not unusual BTW...each stent catheter can
only be used ONCE....thus the "used" catheter is withdrawn..and a `new one\
is inserted over the guide wire....again...not unusal for multiple catheters
to be used...sometimes the stent will not deploy..sometimes the balloon will
not inflate...thus those catheters must be removed..and discarded..no wonder
this can be an expensive procedure(tho defective one can be returned for
credit)...also why there can be a fair amount of blood at the femoral
insertion site....each time a catheter is removed....the docs and nurses
have to apply pressure...then as a new one is inserted...literally arterial
blood is spurting!!!
hopefully you have learned as I did!!! tho I had the majority of the facts
correct...I was wrong in assuming that the stents CAN be threaded OVER the
existing catheters..actually the balloons` AND the stents are part of each
catheter...both come in different sizes etc....
I did not get into drug eluting stents....tho most used now ARE....recent
studies are wondering whether they make much of a difference tho..
if you ask me....the biggest advantage of using plasty...is that the cath
lab can be mobilized in a shorter time than the cardiac operating
suite...thus...folks that arrive in the throes of an acute MI...can be given
thrombolytics...and shortly thereafter...can be ballooned and stented
the key to cardiac survival is the amount of cardiac muscle that is
damaged...
