Acute Coronary Syndrome: primary cause
Atherosclerosis
-Angina occurs when the O2 demand is greater than the oxygen supply
· The heart is working hard (high oxygen demand) but there is poor perfusion to the myocardium (low oxygen supply)
§ Lipids accumulate causing a fatty streak
§ The endothelial lining of the arteries is damaged
Acute Coronary Syndrome: RF
§ Smoking
§ Hyperlipidemia
§ HTN
§ Toxins
§ Diabetes
§ Localized inflammatory process
Acute Coronary Syndrome: S/S
§ Palpitations
§ Diaphoresis
§ Anxiety Nausea
§ Angina (chest pain)
· Women confuse chest pain for indigestion
· Men will describe it as an elephant on the chest
· Both genders will complain of arm pain
Non-ST Elevated Myocardial Infarction (NSTEMI):
§ This is considered Ischemia
· Ischemia means it is lacking O2 NOT tissue death
§ It is reversible
§ Releases cardiac enzymes if damaged
how will an NSTEMI strip look like?
ST Depression and/or T wave inversion indicating ischemia
NSTEMI and STEMI- dx and labs
12 lead EKG
myoglobins
creatine kinase MB
Troponin I or T
Myoglobins
earliest marker of injury to cardiac/skeletal muscle
§ No longer evident after 24hrs
creatine kinase - MB
§ Peaks around 24hrs after onset of chest pain
§ No longer evident after 3 days
Troponin I or T
§ If there is any POSITIVE+ value, it means there is cardiac tissue damage and should be reported
Unstable Angina & NSTEMI MEDS:
o MONA – Morphine, O2, Nitroglycerine, Aspirin
o give heparin to prevent clot formation of microemboli
o DAPT (dual anti platelet therapy) – ex. Aspirin, clopidogrel, ticagrelor
o PCI (percutaneous coronary intervention) – within 12-72 hrs.
§ This refers to cardiac cath with stent placement
o Notify PCP ASAP if there are any changes in ST segment
o ST-Elevated Myocardial Infarction (STEMI):
§ Infarction – Classic heart attack
§ ST segment is elevated = pt is dying
§ Extensive heart damage
§ This is the only one with an ST elevation
· Tissue is dead and more tissue is continuing to die
§ STEMI MEDS:
· PCI (percutaneous coronary intervention) – within 90 mins.
o This refers to cardiac cath with stent placement
· TPA if PCI is not available
o TPA = tissue plasminogen activator = thrombolytic therapy = breaks up existing clots
o PRIORITY NURSING INTERVENTIONS FOR ALL CLIENTS WITH ANGINA:
§ FOR UA, NSTEMI, STEMI
· 12-LEAD ECG
· Serial cardiac biomarkers
· Vitals and O2 monitoring HOURLY
· Continuous ECG monitoring

when do NSTEMI and UA pts go for stent placement
will go to cardiac cath within 72h; these interventions are happening until they go to the cath lab
o ACS Procedures: Angiography/Cardiac Catheterization:

transcutaneous pacemaker
●Fully external
●Symptomatic bradycardia when pt is unresponsive to atropine
●Painful d/t large amount of electricity
●Temporary
epicardial pacemaker
●Pulse generator outside of body
●Leads threaded through chest directly to heart
●Common after open-heart surgery
●Temporary
endocardial (transvenous) pacemaker
●Pulse generator implanted under skin/muscle
●Wires threaded through a large vein and lodged into the wall of the heart
●Permanent (pulse generator will be changed as needed)
●*Some also function as a defibrillator
Implantable Cardioverter/Defibrillator (ICD):
o CONTAINS AN INTERNAL GENERATOR TO DELIVER SHOCK IF NEEDED
§ For pt’s with ventricular dysrhythmias who are at risk of needing D-FIB
§ Ventricular Tachydysrhythmias
§ MI with left ventricular dysfunction
§ For pts who survive sudden cardiac death / ventricular dysrhythmias
§ Stronger shock – will feel like a blow to the chest
pacemaker on demand

fixed pacemaker
the pacemaker will deliver electricity at a fixed rate (less common)
reasons to put a pacemaker in
§ Symptomatic bradycardia
§ Complete heart block
§ Sick sinus syndrome

aneurysm RF
o Male
o Atherosclerosis (most common cause)
o Hypertension
o Smoking
o Hyperlipidemia
o Genetics
o Age (loss of elastin in artery walls causes stiffening/thickening, & progressive fibrosis; more prone to aneurysms & higher mortality rate), etc.
aneurysm types
saccular
fusiform
aneurysm types - saccular
affect only one side of the artery
aneurysm types - fusiform
Affect the complete circumference of the artery
