Coronary artery disease (CAD)/Stable angina FINAL Flashcards
-Episodic pain lasting 5-15 min
-Provoked by exertion
-Relieved by rest or nitro
chronic stable angina
-occurs primarily at rest
-triggered by smoking and increased levels of some substances (histamine, epinephrine)
-may occur n presence or absence of CAD
Prinzmetal’s angina
-more common in women
-triggered by activities of daily living
-treatment may include nitro
microvascular angina
-new onset angina
-chronic stable angina that increases in frequency, duration, and severity
-occurs at rest or w/ minimal exertion
-pain refractory w/ nitro
unstable angina
Usually occurs at points of turbulence (i.e. vessel bifurcations). As plaque increases, arterial lumen progressively narrows→ decreased blood flow to myocardium→ischemia
Atherosclerosis
Sx of angina pectoris (chest pain)
o Pain symptoms vary - ranges from a vague, barely troublesome ache, bloating, gas to a crushing sensation. Common beneath the sternum, may radiate to L shoulder, down the left arm, straight through to the back, into the throat, jaw, teeth.
o Women may have atypical symptoms such as malaise, SOB, Anxiety & Fatigue
What is the #1 modifiable risk factor for CAD?
smoking
What are the 6 P’s for the neurovascular assessment?
Pain
Pulse
Paralysis
Pallor
Paresthesia
Pressure
Cardiac cath pre-procedure considerations
- look for consent, check for metformin (Glucophage) use, or allergies to iodine or shellfish (contrast medium)
- Assess baseline neurovascular assessment, heart & breath sounds, VS
- Teaching Procedure/Post Procedure:
Conscious sedation – awake during procedure
May feel flushing or warmth when dye is injected
Cardiac cath post-procedure considerations
- Sheath Removal – Bedrest, keep extremity straight
- Complications
o Contrast-induced renal dysfunction, Hematoma/Bleeding, & Restenosis - Patient Education re: discharge meds
Medications for CAD
Nitrates, beta blockers, & calcium channel blockers
Beta blockers can cause rebound hypertension. Advise patients that they should never
stop the medication abruptly
With transdermal nitroglycerin (patch):
-apply to a clean, dry, hairless area so medication is better absorbed
-rotate application sites to prevent skin irritation
-remove patch before defibrillation to prevent burns
-remove patch after 12-14 hrs each day to prevent drug intolerance
Beta blockers decrease in HR and cardiac output. Do not administer if
HR is <50-60 bpm or systolic <90-100 mmHg
Watch for signs of HF (cough, edema, SOB, weight gain)
Assess for wheezing & SOB because beta2 blockers causes bronchoconstriction
Calcium channel blockers cause orthostatic hypotension which places patients at an increased risk for
falls esp. elderly pts
