Nursing Priorities in
Acute Coronary Syndromes
Keith Rischer RN, MA, CEN
1
Risk factors for CAD: Multifactorial
Unmodifiable
 Age:

Increased age-CAD begins early and develops
gradually.
 Gender:
 Highest
for middle-aged white caucasian
 Race:
 Caucasian
males highest risk
 Genetic:
 Inherited
tendencies for atherosclerosis
2
Risk factors for CAD: Multifactorial
Modifiable
 Smoking
 Physical
inactivity
 Obesity
 Stress
 Glucose
Intolerance
 Elevated serum lipids
 Hypertension
3
Types of Angina…Causative Factors
Stable (classic)

Pain w/exertion-relief
w/rest
Unstable


Pain onset w/rest
Precursor to AMI


Unrecognized or

Physical exertion
Temperature extremes
Strong emotions
Heavy meal
Tobacco use
Sexual activity

Nursing Assessment: Manifestations
Appearance
 Anxious, restless, pallor, diaphoresis
 Blood Pressure/Pulses
 Breathing
 JVD (Jugular Vein Distension)
 Auscultation/heart and lung
 Abnormal heart sounds S3, S4
Shortness of Breath (SOB)
 Orthopnea
Chest Discomfort
 Pleuritic-point tenderness?
 Localized vs. diffuse
Palpitaion

Diagnostic Assessments


12 Lead EKG
Chest X-Ray:


Assessment of
cardiac size and
pulmonary congestion.
Treadmill exercise

Stress Test on a
treadmill with EKG and
B/P monitor

4- 8 hrs
12 – 24 hrs

12-18 hours
Up to 14 days

Diagnostic Assessments
Angiogram:
 View coronary arteries
 Incr. risk if done after
MI
 Need creatinine

Dye can cause renal
failure
Echocardiogram

Safe, non-invasive, wall
motion abnormalities
17
Nursing Diagnosis Priorities





Acute Pain R/T decreased myocardial oxygen
supply
Ineffective tissue perfusion R/T myocardial
damage, inadequate cardiac output and potential
pulmonary congestion
Activity Intolerance R/T fatigue
Anxiety R/T perceived threat to death, pain,
possible lifestyle changes
Knowledge deficit

Smoking cessation, diet, medications, procedures
–
Assess for dysrhthmias, heart failure, extension of MI
18
Nursing Care Plan
Goals:
Attain adequate pain control
 Maintain adequate tissue perfusion
 Expression of sense of well-being

Evaluation:
Compare progress as a result of nursing interventions
 Effectiveness of pain control
 VS stable: skin color improved
 If interventions unsuccessful – need to make
modifications of NCP
19

Nursing Interventions:Priorities
DECREASE WORKLOAD OF THE
HEART
Preload reduction
Afterload reduction
HR reduction

Pain Relief:


Decrease demand for oxygen consumption






Bedrest, limit visitors, avoid large meals,
Oxygen supplement
complete bed bath/commode avoid straining during BM
Music Therapy, Relaxation Tapes
Watch for dysrhythmias: Increasing PVC’s, VT


Oxygen, Morphine
Amiodorone
Provide emotional support
Spiritual care
20
Nursing Interventions:MI
 Fluid
status
 Monitor
for any symptoms of fluid overload, I&O
 Emotional
 Explain
support to patient and S.O.
procedures/technology, relieve anxiety
 Document
based on unit guidelines
 Patient education/prevention
 Assess
needs early, referrals (SS, cardiac rehab),
others (risk factor management, psychological
adjustment
 Complimentary/alternative
therapy
21
Collaborative Care

Percutaneous
Transluminal
Coronary Angioplasty
(PTCA)

Stent Placement

Coronary Artery
Bypass Graft (CABG)
22
Collaborative Care:Drug Therapy
Antiplatelet agent:
First line of interventionASA, Plavix
Beta-adrenergic blockers:
 Prophylactic for angina
 Inderal, Lopressor,
(decrease in myocardial
contractility
 Lowers HR &
B/P…reduces
myocardial O2 demand
ACE Inhibitors

Improve ventricular
“remodeling”
23
Complications of Acute MI







Dysrhythmias
Cardiogenic shock
Myocardial rupture (of ventricle)
L.V. Aneurysm
Pericarditis
Venous Thrombosis
Psychological Adjustments

Angio: occluded prox. LAD-opened x3 stents BP-78/46
– Dopamine & Epinephrine gtts started
– IABP placed-transfer to ICU


Usually stays in ICU 1 or 2 days
–




assess for post-op pain
administer ordered pain meds
Cardiac tamponade
Monitor electrolytes
–

K+
Assess for dysrhythmias
–

Vented 3-6 hours after surgery
Atrial fib most common
Chest tubes
–
–
Milking q 1-2 hours
Assess amount/color drainage
29
Chest Tube: Nursing Priorities





Assess resp. status closely
Check water seal for
bubbling
Milk NOT strip every 2
hours
Assess color-amount
drainage
 Call MD if >100cc/hr x2
hours first 24 hours
Sterile guaze/occlusive
dressing at bedside
