Note:
Before we progress further into this relatively complex case,
please review module 6 in the Case Study
Workbook: The Heart, Pathway of Blood Flow, Coronary Blood
Supply, and Myocardial Ischemia and Infarction. Visit the following sites and review heart biology for
better understanding of the physiological basis of an acute
myocardial infarction.
1.
The
Heart. Good
review of basic heart anatomy and physiology. Links to related
subjects such as the composition of blood. Don't get overwhelmed
with this site! Have fun with it. You will only be
responsible for the material covered in the objectives.
Look for the following sites (the answer key gives you directions
on how to find these sites if you're lost):
5.
Find and view the slide show on the structure of a preserved
heart. This is interesting to view but in depth. You
will not be tested on this!
6.
Study the structure of the heart. Learn about the roles of
blood vessels including arteries, veins, and capillaries.
7.
Describe the pulmonary, coronary and systemic circulatory
systems.
8.
What prescription is given for a healthy heart?
9.
How can the heart's health be monitored by a physician?
10.
Define echocardiograph.
11.
Define electrocardiography.
12.
List invasive heart procedures
Did
you watch the open heart surgery video? You must download quick
time
to view.
(Click on "structure" from home
page. From here click on "heart surgery."
Click on "open heart surgery.")
2.
MedicineNet.com
Power
points on myocardial infarctions. You may need your medical
dictionary, but the intent is to gain an overview of this
life-threatening disease. This is a good overall review site for
this case prior to taking the case post test.
After
studying this website the student should be able to:
Define:
ischemia, angina, cardiac enzymes, angiogram, arterioscleroses,
cholesterol and relationship to plaque formation,
infarction
and hypertension (See objective 3).
Outline
and define the physiologic/pathophysiologic sequence of events
that lead to an acute myocardial infarction (AMI). (See objective
4).
List
common symptoms in an acute myocardial infarction (AMI) (See
objective 5).
List
common risk factors associated with an AMI (See objective 6).
Define
the following as to their relevance to an AMI: angiogram,
angioplasty, coronary bypass surgery, beta blockers,
thrombolytics, such as heparin and streptokinase (See objective
8).
These
questions/objectives are not referred to in the "answers to
case questions" section. All of the answers can be
found in the above web site. Make sure to check out the
medical dictionary. Please review site in detail!
3.
NOVA
(from the television series). Excellent graphical representation
of the "troubled heart" with pictures of normal and
abnormal arteries. Good animation of cardiac blood flow.
Review
treating heart problems that contains sections on risk factors
and treatment.
Review
"troubled hearts" that contains pictures of normal and
abnormal hearts and arteries.
Review
"Map of heart" that includes an excellent
animation depicting cardiac blood flow.
4.
Echocardiography.
There are many sites that address these important tools for
assessing cardiac function. This site is a decent primer.
13.
Describe how an echocardiogram works.
14.
List information about the heart that can be gained from an
echocardiogram.
15.
What information cannot be learned from an echocardiogram.
16.
Which health professional would be responsible for performing an
echocardiogram?
