A 67 year old male is UNSTABLE ANGINA
admitted with chest pain
after collapsing at home. The change in quality, frequency, and duration
He is arguing with his wife indicates UNSTABLE ANGINA and may indicate that
that he should not be the pt is at increased risk for an MI. This pt should be
admitted because he "just closely monitored for EKG changes and rhythm
over did it" while working disturbances. Pt/ family teaching should begin on how
in the world. Lee's wife to identify an MI and basic CPR.
states to you that his chest
pain is more frequent,
severe and prolonged
than before. You should
anticipate what diagnosis?
• Exertional angina
• Unstable angina
• Variant angina
• Stable angina
,An absolute TRAUMATIC CPR
contraindication for use of
a fibrinolytic would be? Other absolute contraindications are:
• Traumatic CPR HYPERTENSTION
• Cerebrovascular disease BLEEDING DISORDERS
• Subacute bacterial
endocarditis The other options are relative contraindications.
• Oral anticoagulants
Actions of beta blockers INCREASED DIASTOLIC FILLING TIME
include?
• Increased myocardial
oxygen demand
• Increased heart rate
• Increased diastolic filling
time
• Increased afterload
Afterload is the amount of pressure the left ventricle
must work against to pump blood into the circulation.
The greater this resistance, the more the heart works
to pump out blood.
Afterload refers to the pressure that the ventriclar
Afterload
muscles must generate to overcome the higher
pressure in the aorta to get the blood out of the heart.
RESISTANCE is teh know on the end of the balloon,
which the balloon has to work against to get the air
out.
,Alpha-adrenergic effects Peripheral arteriolar vasoconstriction
of norepinephrine
include? Increased force of myocardial contraction
• Increased force of Increased SA node firing
myocardial contraction Increase AV conduction time
• Increased SA node firing • These are all affects of beta-adrenergic sympathetic
• Increase AV conduction stimulation
time
• Peripheral arteriolar
vasoconstriction
An aneurysm that is In the chest and midscapular area
dissecting upwards
(ascending) produces Quite often the patient will describe a ripping or
pain: tearing sensation and severe pain. Hypotension may
be present as the dissection progresses. Warning
-In the chest and signs include hypertension, a new murmur (aortic
midscapular area insufficiency), weak peripheral pulses, and possible
-In the back of the neck deterioration of LOC.
and left shoulder Aneurysms that dissect downwards (decending)
-From the umbilical area radiate pain to the lower abdomen, lower back and
to the shoulder legs.
-In the left shoulder and
midsternal area.
An anterior wall infarct V2, V4 -anterior wall
may be seen in leads?
• V4, R V4, R -right ventricular damage
• V5, V6 V5, V6 -apical injury
• V7, V9 V7, V9 - posterior wall
• V2, V4
, An aortic aneurysm that 5 cm
extends more than _____ cm
will require surgical repair. Any aortic aneurysm that extends over 4 cm will need
surgical repair. Other criteria for immediate repair
-3 cm include impending rupture, limb ischemia,
-5 cm uncontrolled pain, cardiac tamponade, and increasing
-7 cm size.
-9 cm
Located where the LEFT ventricle meets the aorta. It
allows blood to flow from the LEFT ventricle to the
Aortic Valve
aorta and prevents backflow. Has 3 cusps. Semi-lunar
Valve.
75%
Approximately what % of
coronary artery blockage
Anginal pain usually occurs when approximately 75%
is needed to cause
of the artery becomes occulded. Pain is more
angina?
pronounced with exertional or emotional distress
when oxygen demand by cardiac tissues cannot be
-45%
met by the oxygen supply via the ocluded artery. The
-60%
severity of the pain may be compounded by
-75%
vasospasms that further restrict blood flow through
-90%
the coronary arteries.
