Angina Pectoris is ____.
|
chest pain
|
|
Angina pectoris is caused by a inadequate imbalance between _____ and the demand for myocardial contractility.
|
myocardial oxygen supply
|
|
The demand for oxygen is controlled by
|
preload
afterload contractility heart rate |
|
The myocardial oxygen supply is met with
|
arterial oxygen content and coronary artery blood flow
|
|
When a person has angina there is significant atherosclerosis and there is decreased ____ with increased _____.
|
supply
demand |
|
Situations in which oxygen demands are increased are:
|
-exercise
-stress -higher elevations -anxiety -cold |
|
When a person has chronic atherosclerosis for years they develop channels between small arteries that provide alternative routes for blood flow. This is called _____.
|
collateral circulation
|
|
Collateral circulation hopefully minimizes the amount of _____.
|
dead tissue in the event of an MI.
|
|
There are 3 types of angina:
|
-stable
-unstable -Prinzmetal's/Variant |
|
___ angina is triggered by predictable pattern of onset, duration and intensity relieved by rest and or NTG.
|
Stable
|
|
____ angina is unpredictable, not relieved by rest or nitrates and lasts longer than stable angina.
|
Unstable
|
|
____ angina occurs with rest and is due to coronary artery spasm.
|
Prinzmetal's/Variant
|
|
Clinical manifestations of angina are pain that might feel
|
-tight
-squeezing -heavy -constricting substernal pain that radiates to jaw, epigastric area and back |
|
Additional manifestations of angina pectoris are:
|
-dyspnea
-pallor -tachycardia -great anxiety or fear |
|
Anginal symptoms in women include:
|
-indigestion
-nausea -vomiting -upper back pain -FATIGUE |
|
Management of Angina Pectoris focuses on maintaining ____ and _____.
|
coronary blood flow and cardiac function
|
|
Assessment of chest pain includes:
|
-pain scale (0-10), PQRST
-LOC, tissue perfusion -VS, heart rhythm, pulse ox -Dx: 12 lead EKG, lab tests |
|
PQRST=
|
Precipitating factors
Quality (describe pain) Radiation Relieving factors Severity Symptoms Timing |
|
Goals of angina treatments are
|
-reduce frequency of anginal episodes
-terminate acute anginal pain in progress |
|
Angina medications do 4 things:
|
-slow HR
-dilate veins so heart receives less blood (less preload) -cause heart to contract with less force (reduced contractility) -offer heart less resistance when ejecting blood from LV (reduced afterload) |
|
Anti-anginal meds dilate veins so that the heart receives less blood. This reduces _____.
|
preload
|
|
Anti-anginal meds cause the heart to contract with less force. This reduces ______.
|
contractility
|
|
Anti-anginal meds offer the heart less resistance when ejecting blood from the LV. This causes reduced _____.
|
afterload
|
|
3 types of anti-anginal drugs are:
|
-Nitrates
-Beta blockers -Calcium Channel blockers |
|
The mainstay drug therapy for angina is _____.
|
Nitrates
|
|
The major difference between the routes of administration for nitrates is the
|
onset of action and rate of elimination
|
|
Nitrates are a _____.
|
vasodilator
|
|
Nitrates dilate arterioles and venules. Dilated arterioles cause decreased ____ and decreased _____.
|
peripheral resistance
afterload |
|
Nitrates also dilate venules which decreases ____ and decreases ____.
|
venous return and preload
|
|
Adverse effects of nitrates include:
|
-h/a
-dizziness -orthostatic hypotension -rash -rapid drug tolerance |
|
___ is not an issue with ER nitrate tablets.
|
Headache
|
|
____ is an issue with nitrates therefore it is important to have a drug free period.
|
Rapid Drug tolerance
|
|
A major adverse effect of nitrates is
|
syncope related to orthostatic hypotension
|
|
Nursing care for nitrates includes:
|
-BP and HR prior to administration
-proper and careful application -consult MD prior to taking erectile dysfunction drugs |
|
____ is rapid acting and given for acute episodes of angina.
|
Sublingual nitrate
|
|
If apt with angina pectoris has CP they should
|
take 1 sublingual NTG, wait 5 min.
if no relief call 911 and take 2nd wait 5 min and take 3rd |
|
Propanolol
Atenolol Metoprolol Nadolol are types of |
Beta blockers
|
|
If a patient has respiratory problems and angina they will take a ____ because it only works on the heart.
|
selective beta blocker
|
|
Beta 1 Blockers affect the ____.
|
heart
|
|
Beta 2 Blockers affect the ____.
|
lungs
|
|
Beta blockers cause decreased ____ and _____ which results in decreased myocardial oxygen demand and decreased angina.
|
heart rate and myocardial contractility
|
|
Beta blockers keep ___ and ____ from attaching to receptor sites when the SNS is initiated.
|
epinephrine and nor-epinephrine.
|
|
Adverse effects of beta-blockers include:
|
