10 minute topic Cardiovascular diagnostics and Procedures Flashcards
When are Cardiac enzymes released?
hen the heart muscle suffers ischemia
the heart isn’t getting enough oxygen
When is a lipid profile used
detects cholesterol levels and is used for early detection of heart disease
Indications for running cardiac enzyme or lipid tests
Angina
MI – s/s of MI
Heart disease – a patient with known heart disease and comes in with other s/s
Hyperlipidemia
CK-MB range
30-170 but really should be 0
CK-MB time of elevation
elevates within 4-6 hours of myocardial injury
stays elevated for 3 days
Troponin T range
<0.2ng/L
Troponin T time of elevation
elevates within 3 hours of MI
stays elevated for 2-3 weeks
Troponin I range
0.03 ng/L
Troponin I time of elevation
elevates within 3 hours of MI
Stays elevated for 10 days
Myoglobin range
<90mcg/L
Myoglobin time of elevation
elevates within 2 hours of MI
Only stays elevated for 24 hours
HDL ranges
35-65mg/dl for men
35-80 mg/dl for women
LDL cholesterol levels
<130-180 mg/dl
Triglycerides
should be <150
used to evaluate for atherosclerosis
Echocardiogram
ultrasound of the heart used to dx valve disorders
looking at the actual structure of the heart
Candidates for an ECG
cardiomyopathy
HF
angina
MI
Pharmalogical stress test
Adenosine is given if PT is unable to walk on treadmill
Stress test candidates
Angina
heart failure
MI
dysrhythmias
Cardiac Angiography (AKA cardiac catheterization)
invasive diagnostic procedure to evaluate the presence and degree of coronary artery blockage
Cardiac Angiography (AKA cardiac catheterization) procedure
occlusions are seen by injecting contrast media under fluoroscopy
Cardiac Angiography (AKA cardiac catheterization) indications
unstable angina w/ ECG changes
to determine extent and location of known heart disease
Cardiac Angiography (AKA cardiac catheterization) pre-procedure
NPO for 8 hours due to aspiration risk
Check BUN and creatanine because the dye is excreted through the kidneys
check for shellfish or iodine allergy
Cardiac Angiography (AKA cardiac catheterization) intra procedure
client is awake
local anesthetic
client will feel warm flushing
pressure to be placed on incision to prevent bleeding
Cardiac Angiography (AKA cardiac catheterization) post procedure
monitor pedal pulses
we are on the arterial side so a clot would go toward to feet
Supine position
Continuous cardiac monitoring
