Nuclear Cardiology
|
Nuclear cardiology shows how well
blood flows to the heart muscle. By
producing an image of the heart,
radioactive "tracers" like thallium
and cardiolyte can increase the
accuracy of the traditional stress
test. This is done along with an
exercise stress test on a treadmill,
but can also be carried out with
help of medicines like adenosine and
dipyridamole that simulate the
effects of exercise on the
heart. Nuclear cardiology imaging
determines whether coronary artery
stenoses or blockages are severe
enough so as to limit blood flow to
heart muscle when it needs it the
most that is during physical
activity. The nuclear imaging also
allows a determination of the
heart’s pumping function.
When the patient reaches his or her
maximum level of exercise, a little
amount of tracer is administered
into a vein. The patient then lies
down on a table under a special
camera that records the energy
emitted from the radioactive tracer
and generates images or scans that
reflect the heart’s blood flow, at
rest as well as following stress. If
a part of the heart muscle does not
receive adequate blood supply, a
deficiency of tracer activity in
that area will show up on the
finished images as a “defect".
In the nuclear cardiology test, if
the scan is normal during exercise
as well as rest, then blood flow
through the coronary arteries is
taken to be normal. In this case
then no significant
coronary artery blockage is
suspected. In the test, if the scan
is normal at rest but abnormal
following
exercise, that means the heart
is not receiving adequate blood when
under stress. This indicates
blockage in one or multiple coronary
arteries. During the test, if
abnormal blood flow is observed both
at rest and with stress, this may
mean that part of the heart has
suffered injury in the past. This is
usually the case following a
heart attack.

Nuclear Cardiology and Heart Disease |
The
main cause of death in the western
world is
heart
disease. Every year in
the U.S.A, over 500,000 men and
women die from
coronary
artery disease. During
the past two decades, significant
strides have been made in the
diagnosis and treatment of heart
disease. Nuclear Cardiology has
played the most important role in
establishing the diagnosis of heart
disease as well as in the assessment
of the disease extent and the
prediction of outcomes seen from the
point of view of coronary artery
disease.
Nuclear cardiology studies use
noninvasive methods to assess
myocardial blood flow,
evaluate the pumping ability of the
heart as well as visualize the size
and location of a heart attack.
Among the different techniques of
nuclear cardiology,
myocardial perfusion imaging
is the one mostly used.
Myocardial perfusion
Myocardial perfusion images
are
combined with exercise to determine
and assess the blood flow to the
heart muscle. These studies can
detect areas of the heart muscle
that have poor blood supply as well
as the parts of heart muscle that
are damaged from a
heart
attack. Myocardial
perfusion studies assess the extent
of the heart muscle with a limited
blood flow and provides information
about the pumping capacity of the
heart.
Radionuclide Ventriculography
Radionuclide ventriculography is a
noninvasive study, which gathers
information regarding the pumping
function of the heart. In patients
suffering from coronary artery
disease, and in those who have
already had a heart attack, the
assessment of the pumping function
of the heart is important in the
prediction of both long term and
short-term survival. A little dose
of an imaging agent is administered
in the blood stream and pictures of
the four chambers of the heart taken
using a special camera. The
evaluation of cardiac function with
radionuclide ventriculography is
very reliable and plays a critical
role in predicting outcomes in
patients with heart disease.
Myocardial Injury, Infarction and
Infection
The basic cellular component of the
heart muscle may be hugely affected
in the setting of a limited blood
supply or inflammation. Nuclear
cardiology can be applied to
determine which parts of the heart
muscle have been affected by
infection or by a heart attack.
Positron -Emission Tomography
PET
studies are noninvasive and
essential to provide information
about the blood supply to the heart
muscle as well as the metabolic
activity of the heart. These studies
detect the heart muscle that is not
receiving adequate blood flow
because of the blockage in the
arteries of the heart. These studies
can also spot the heart muscle that
has been damaged from past heart
attacks.
Nuclear cardiology studies continue
to play an essential role in the
noninvasive diagnosis of coronary
artery disease, the assessment of
the pumping capacity of the heart
and in the prediction of outcomes in
patients with heart disease.

Nuclear Cardiology |
Nuclear cardiology is the study of
the heart with help of small amounts
of radioactive tracers. It enables
the study of the function of the
heart non-invasively.
Myocardial perfusion imaging
is the most commonly used test in
nuclear cardiology. This is a form
of
stress test
which uses myocardial perfusion
tracers and gamma camera imaging
methods to determine the adequacy of
blood flow to the heart, as well as
to find out if how much of the heart
muscle may have been scarred and
damaged beyond repair. It is often
used for the detection of
coronary
artery disease
(narrowing of the heart arteries)
and also for the assessment of the
extent of its effects on blood flow
to the heart and myocardial
viability.
The major difference between
coronary
angiography
and stress nuclear scans is that
angiography primarily provides
information about the presence and
severity of a narrowing, while
nuclear scans provide information
about the effect of the effect of
that narrowing on blood flow and
heart muscle function. This blood
flow and function information is
critical for determining if
angioplasty
or bypass surgery is required, but
is not routinely available from
angiography. This also explains why
there is sometimes discrepancy
between the results of angiography
and nuclear tests. Since all
narrowings in the heart arteries do
not cause impaired blood flow, not
all patients with coronary artery
disease will have abnormal nuclear
scans. Hence, not all patients with
heart disease will have an abnormal
stress nuclear scan, and there can
never be 100% accuracy guaranteed
for detection of narrowing of
arteries. However, in the presence
of a normal scan, indicating normal
blood flow, the possibility of
disease is low and the prognosis is
good, so that further investigation
is not warranted at that point in
time.
Stress nuclear scans is very
important when it comes to managing
patients with coronary artery
disease by means of providing more
reliable detection of disease than
the standard stress ECG and
additional useful information about
blood flow and function which is not
obtained from the coronary angiogram
alone. The correct assessment of the
severity and extent of abnormal
blood flow, is often crucial in
deciding whether the patient should
undergo coronary angiography, bypass
surgery or balloon angioplasty.

Nuclear Cardiology and Heart Disease
|
Coronary Heart disease is the
leading cause of death in the world.
In the United States alone more than
500,000 people die from
coronary artery disease
. In the last 20 years major
inroads have been made in the
diagnosis and treatment of heart
disease. Nuclear Cardiology is
playing an important role in
establishing the
diagnosis of heart disease
and
in the assessment of the extent of
disease extent and prediction of
outcomes.
Nuclear Cardiology
Myocardial perfusion imaging
is the most common nuclear
cardiology technique used. Usually
Nuclear cardiology studies use
noninvasive techniques to assess
blood flow, evaluate the pumping
function of the heart and to
visualize the size and location of a
heart attack .
Myocardial Perfusion Imaging:
Myocardial perfusion images
are combined with exercise to
assess the blood flow to the heart
muscle, exercise may be in the form
of walking on the treadmill or
riding a stationary bicycle. For
people who are unable to perform
exercise maximally a "chemical"
stress test using the drug
dipyridamole, adenosine or
dobutamine may be used to gather
similar information about the
heart's blood flow.
A small amount of an imaging agent
{thallium or sestamibi or
tetrofosmin (Myoview), is injected
into the blood stream during rest
and during exercise or chemical
stress then a scanning device (gamma
camera) is used to measure the
uptake by the heart of the imaging
material during (exercise or
chemical stress) and at rest. If
there is significant blockage of a
coronary artery, the heart muscle
may not get enough of a blood
supply, this decrease in blood flow
will be reflected in the images.
Myocardial perfusion studies are
able to spot areas of the heart
muscle having an inadequate blood
flow as well as the areas of heart
muscle that are damaged as a result
of a heart attack. The studies
localize the coronary artery with
atherosclerosis, quantifies the
extent of the heart muscle with a
limited blood supply and can also
provide information about the
pumping function of the heart.
Hence, it is superior to usual
exercise stress testing and provides
crucial information which helps in
identifying patients at an increased
risk for a heart attack who may be
candidates for invasive procedures
such as
coronary angiography,
angioplasty and heart surgery.
Evaluation of Cardiac Function by
means of Radionuclide
Ventriculography
Radionuclide ventriculography is a
noninvasive study, which provides
information about the pumping
capacity of the heart. In patients
with coronary artery disease, and in
those who have had a heart attack,
determination of the pumping
function of the heart (also known as
the ejection fraction) is required
for the prediction of both long term
and short-term survival. A little
amount of an imaging agent is
injected into the blood stream and
pictures of all four chambers of the
heart are taken with a special
camera (gamma camera). These
techniques also provide information
about the function of the valves of
the heart, the integrity of all the
cardiac chambers and can be applied
to monitor the effect of different
drugs on the heart muscle (in
patients with cancer who are
administered chemotherapy). The
evaluation of cardiac function with
radionuclide ventriculography is
accurate and noninvasive and plays a
very important role in predicting
outcomes in patients with heart
disease.
Assessment of Myocardial Injury,
Infarction and Infection
The basic cellular component of the
heart muscle may be affected in the
setting of a limited blood supply
and or inflammation, which cannot be
reversed. Nuclear cardiology
techniques can be used to find out
areas of the heart muscle that have
been damaged by infection, heart
attack etc. These techniques can
also be applied to monitor the
status of the heart muscle in the
patient after cardiac
transplantation.
Imaging of the Nervous System of the
Heart
The heart has a nervous system of
its own, which is essential for the
proper functioning of the heart
muscle. If there is damage to the
heart muscle, the nervous system of
the heart can be impaired resulting
in abnormal function of the
electrical system of the heart. An
abnormal heart rate and disruption
of the normal cardiac rhythm can
display this abnormality. Imaging
agents are administered into the
blood stream and then the nervous
system of the heart can be imaged
with a gamma camera. The information
acquired from these noninvasive
studies can be utilised in the
management of patients with heart
disease, especially heart failure.
Positron -Emission Tomography (PET)
PET studies are noninvasive and are
used to find out information about
the blood supply to the heart muscle
as well as the metabolic activity of
the heart. These studies can find
out the heart muscle that is not
getting enough supply of blood due
to the blockage in the arteries of
the heart. These studies spot the
heart muscle that has been damaged
from past heart attacks, and also
what has been damaged but has the
potential to recover if a bypass
surgery or an angioplasty is
performed. This ability to
distinguish irreversibly damaged
heart muscle from damaged heart
muscle with a potential to recover
its function after bypass surgery or
angioplasty is a major strength of
PET imaging and makes it
indispensable. PET studies can also
be applied to evaluate the nervous
system of the heart. These studies
can also assist in making
determinations about candidacy for
bypass surgery or angioplasty. With
increase in the availability of PET
imaging cameras, the use of PET
imaging has also increased
considerably in the last few years.
SUMMARY
Nuclear cardiology studies play an
increasingly crucial role in the new
millennium, in the noninvasive
diagnosis of coronary artery
disease, the assessment of the
pumping capacity of the heart as
well as in the prediction of
outcomes in patients suffering from
heart disease.

What
is nuclear cardiology? |
Nuclear cardiology uses small
amounts of radioactive material to
obtain information about the heart.
With this technology, developed in
the 1960's and 1970's, the nuclear
cardiologist may assess the heart
muscle. Like a stress echo test,
nuclear cardiology studies produce
images of the heart at work (during
exercise) and at rest. During a
test, you are given an injection of
a small dose of a harmless
radioactive tracer. Then you spend
time exercising on a treadmill or
stationary bicycle and then resting.
A specialized camera (called a
"gamma camera") detects the tracer
as it passes through the chambers of
your heart, creating the pictures.
The pictures may reveal problems in
heart muscle and blood vessels,
especially when the images of the
heart at work and at rest are
compared. |

most
commonly used test in nuclear
cardiology |
The
most commonly used test in nuclear
cardiology is called myocardial
perfusion imaging. This is a form of
stress test which makes use of
myocardial perfusion tracers and
gamma camera imaging methods to
assess the adequacy of blood flow to
the heart, as well as to find out if
how much of the heart muscle is
viable (alive) and how much is
scarred and damaged beyond repair.
It is a diagnostic tool that is
often used for the detection of
coronary artery disease (narrowing
of the heart arteries) and for the
assessment of the severity and
extent of its effects on blood flow
to the heart and myocardial
viability. |
|
|
South London |
How it
works |
During
the stress nuclear test, a small
amount of a radioactive perfusion
tracer (such as thallium, sestamibi
or tetrofosmin) is injected into a
hand vein while the patient is
undergoing stress testing. These
tracers are taken up by heart muscle
in proportion to blood flow. Areas
of myocardium with impaired blood
flow or viability will have reduced
tracer uptake. The uptake of tracer
in the heart is then assessed by
imaging the patient with a gamma
camera, which is capable of
detecting the small amounts of
radiation emitted by the tracer. By
rotating the camera around the
patient to take multiple views from
different angles, a 3-dimensional
image of the distribution of tracer
in the heart can be reconstructed
using computerised methods (Single
photon emission computed tomography,
or SPECT). The uptake of tracer in
the heart can then be assessed in a
tomographic (3-dimensional) way,
which avoids overlap between
different parts of the heart and
allows us to localise the area and
extent of any abnormalities with
greater accuracy.
This technique is more accurate for
detecting abnormal blood flow and
heart disease than the standard ECG
stress test. |
|
|
Great Britain, GB |
how to
interpret results |
A
normal scan will show uniform uptake
of tracer throughout the heart,
indicating that blood flow during
stress is increased evenly
throughout the heart. The likelihood
of significant narrowing of heart
arteries (coronary artery disease)
is low, the prognosis is good and no
further operation (angioplasty or
bypass surgery) is usually
indicated, since there is no
evidence of insufficient blood flow.
An abnormal scan will show one or
more areas of reduced tracer uptake
following stress injection, and this
can either be due to reduced blood
flow to the heart or damaged heart
muscle due to a previous heart
attack (or a mixture of the two). A
rest study (which may involve a
second scan with or without a second
injection of tracer at rest) is
needed to distinguish between the
two. The detection of a large amount
of heart muscle with insufficient
blood flow during stress indicates
that the patient is likely to
benefit from balloon angioplasty or
bypass surgery. With the use of
certain tracers, additional
information on heart function can
also be obtained by using a special
method of imaging called ECG-gated
SPECT. |
|
|
|
When
are stress nuclear scans used? |
Stress
nuclear scans are useful in the
detection of coronary artery
disease, particularly when standard
ECG stress testing is not possible
or non-diagnostic. For instance,
when the patient is unable to
exercise or achieves an inadequate
level of exercise on a treadmill,
when the resting ECG is difficult to
intepret or when the result of
stress testing is borderline, then a
stress nuclear scan is helpful. The
overall sensitivity of the stress
nuclear scan (83% to 98%) is higher
than that of the standard ECG stress
test (average 68%).
For patients who are unable to
exercise, stress testing can be
performed using drugs such as
dipyridamole, adenosine or
dobutamine which have been shown to
have high accuracy for detection of
coronary artery disease when used in
combination with nuclear cardiac
imaging. In patients with known
coronary artery disease on
angiography, nuclear scans are often
used to assess the effect of a
narrowing in the arteries and to
help decide if bypass surgery or
balloon angiogioplasty is needed.
A normal stress perfusion study
indicates a good prognosis and a low
likelihood of sudden heart attack
(approximately <1% cardiac event
rate per year), even in the presence
of known disease of the heart
arteries, and in most cases, allows
the patient to avoid having an
angiogram, which is a test which
involves inserting a tube(catheter)
into the heart and injecting dye to
outline the arteries.
In patients with damaged hearts due
to a previously heart attack
(myocardial infarction), perfusion
imaging is often used to assess the
risk that the patient may develop
further heart attacks and help
decide whether an angiogram, bypass
surgery or balloon angioplasty is
indicated.
In patients with known or suspected
heart disease who are due for
general (non-heart) surgery,
myocardial perfusion imaging using
pharmacologic stress is also used
for assessment of risk before
operation, particularly in patients
due for surgery on their leg
arteries who are unable to exercise. |
|
|
|
Practical aspects of stress nuclear
scanning |
On the
day of the test, patients are
advised to bring jogging shoes and
attire. For those who cannot
exercise, pharmacologic (drug)
stress will be employed. Patients
are advised not to take caffeine
containing drinks (coffee, tea,
colas) on the day of the test, since
this can interfere with the action
of dipyridamole, which is often used
in stress testing with drugs. A
light breakfast is allowed. Patients
who are taking medications such as
beta-blockers are also advised to
stop these for 3 to 5 days before
the test, depending on the half-life
of the drug, and provided their
physicians are agreeable.
Alternatively, the patient can still
be tested, by using drugs. Patients
are then either exercised on a
treadmill or undergo stress testing
using drugs such as dipyridamole,
adenosine or dobutamine, and the
tracer is injected into a hand vein
at the time of peak stress. Imaging
with the gamma camera is performed
half to one hour later, and takes 20
minutes to complete. If a rest scan
is needed, this is performed 3-4
hours later, or on another day,
depending on convenience. |
|
|
|
Safety
and radiation concerns |
The
total radiation exposure for
patients undergoing stress nuclear
scans is well within the level of
what is considered safe. Considering
that the nuclear test is being used
to determine if the patient needs to
undergo an angiogram or an
angioplasty (or bypass surgery),
this low amount of radiation
exposure from stress nuclear scans
appears to be quite acceptable. |
|
|
|
Summary |
In
summary, stress nuclear scans have a
important role to play in the
management of patients with coronary
artery disease by providing more
accurate detection of disease than
the standard stress ECG and
additional useful information about
blood flow and function which is
usually not available from the
coronary angiogram alone. This
information, particularly the
accurate assessment of the severity
and extent of abnormal blood flow,
is often critical in deciding
whether the patient should be
undergo coronary angiography, bypass
surgery or balloon angioplasty. |

Nuclear Cardiology |
Nuclear Cardiologist
studies use
noninvasive
techniques to assess
myocardial blood
flow, evaluate the
pumping function of
the heart as well as
visualize the size
and location of a
heart attack. Among
the techniques of
nuclear cardiology,
nuclear
cardiologist,
myocardial perfusion
imaging is the most
widely used. Nuclear
cardiologist
Myocardial perfusion
images are combined
with exercise to
assess the blood
flow to the heart
muscle. Exercise can
be in the form of
walking on the
treadmill or nuclear
cardiologist, riding
a stationary
bicycle. A
"chemical" stress
test using the drug
dipyridamole,
adenosine or
dobutamine be
performed in
patients who are not
able to exercise
maximally,nuclear
cardiologist
providing similar
information about
the heart's blood
flow. |

Nuclear Cardiologist
studies continue to
play an increasingly
important role in
the new millennium,
in the noninvasive
diagnosis of
coronary artery
disease, the
assessment of the
pumping function of
the heart and
nuclear cardiologist
in the prediction of
outcomes in patients
with heart disease.
Nuclear cardiologist
procedures are
performed by
cardiologists in
hospitals, clinics,
and private offices.
Such a facility must
have a license from
the government,
nuclear cardiologist
which is only issued
after a thorough
evaluation of the
facility and the
physician's
training, nuclear
cardiologist. |

Heart-Scan Advantage
l amounts of radioactive
substances for the diagnosis of heart disease. Radioactive substances
are administered and the amount of radiation emitted measured to assess
abnormalities in its structure and function. Nuclear Cardiology
provides a powerful and precise tool in the field of heart disease
detection. Myocardial Perfusion (MPI) and Thallium scanning are
Nuclear Cardiology procedures used in the diagnosis of heart disease.
