Acute Coronary Syndrome – Orientation Overview
Acute Coronary Syndrome
(Simulation in Nursing Education)
Debriefing/Guided Reflection Overview
In New Zealand the following is true:

Cardiovascular disease (heart, stroke and blood
vessel disease) is still the leading cause of death in
New Zealand, accounting for 30% of deaths
annually (2010 Ministry of Health Mortality data).

The CHD death rate is more than twice as high in
men as in women.

Mortality rates for Maori from cardiac related disease
are higher than non-Maori (2-4x higher). Therefore,
Maori need to be assessed 10 years earlier for risk
factors than non-Maori.

Pacific Island peoples do not have quite as high
cardiac risk as Maori, higher than non-Maori.
(New Zealand Health Information Service,
2001).
RISK FACTORS:

Non-modifiable risk factors:
o Family history of coronary heart disease
o Increasing age
o Gender
o Ethnicity


Modifiable risk factors:
o High serum lipids (LDL’S)
o Cigarette smoking
o Hypertension
o Diabetes Mellitus
o Physical inactivity
o Obesity
Management of care--management of coronary
clients involves the following nursing
interventions:
AUT

Report to student
Time: 1330
Carl Shapiro is a 54-year-old male who travels frequently
on business. He has had two previous heart attacks with
subsequent stents placed in his right and circumflex
arteries. He sought help in the ED and has been
transferred to your cardiac ward with complaints of dull
aching chest pain and shortness of breath. He is
currently visiting the area on business so has no local
GP. He has a 40 pk/year smoking history and drinks
alcohol occasionally. He describes work as ‘stressful.’

Ventricular fibrillation and pulseless ventricular tachycardia are included in the Pulseless Arrest Algorithm. This is the most important algorithm in ACLS,
and one that should be mastered. Both are shockable rhythms, in contrast to PEA and asystole, which fall on the right side of the algorithm.
The ventricular fibrillation and pulseless ventricular tachycardia algorithm can be found here. The high resolution PDF for member download can be found
here.
Ventricular fibrillation is the most common rhythm experienced by patients who experience cardiac arrest. This is why so much emphasis in ACLS is placed
upon learning and memorizing this rhythm and its treatment. Evidence reveals that rapid treatment of ventricular fibrillation using the ACLS pulseless arrest
algorithm is the best way to achieve return of spontaneous circulation (ROSC).
The following points are essential to remember when treating a patient using the Pulseless Arrest Algorithm for ventricular fibrillation and pulseless ventricular
tachycardia:
1. Until the defibrillator is attached to the patient, high quality CPR should be performed.
2. Interruptions in chest compressions should be minimized.
3. Rapid use of the defibrillator is the key component of treatment for VF and VT.
4. Use of an AED may involve prolonged interruptions in chest compressions for analysis of the rhythm and administration of shock. Use a manual
defibrillator if available.
o Stacked shocks are no longer used.
o CPR should be resumed for five cycles between each shock.
Defibrillation and Shock
We will be using AEDs as students have not been trained in defibrillation with paddles at this point. Paramedicine has advised use of AEDs due to lack of
previous skill training with paddles.
Vasopressors
Definition: A vasopressor is a medication that produces constriction of the blood vessels, with a subsequent rise in blood pressure.
In the treatment of ventricular fibrillation and pulseless ventricular tachycardia, the vasopressors used in the ACLS algorithm are Adrenaline and vasopressin.
While Adrenaline is primarily used for its vasoconstrictor effects, vasopressin increases blood flow to the brain and heart, and has vasoconstrictor effects similar
to those of Adrenaline.
Anti-arrhythmic
Amiodarone, lidocaine, and magnesium are the antiarrhythmic medications used in the pulseless arrest algorithm. More detailed information about these
medications is located here. Rhythm checks should be limited to 10 seconds and should be performed after 5 cycles of CPR, to minimize interruptions in
CPR.
