25
When will you experience the signs of unstable angina?
Very suddenly and the episodes can not be predicted
26
If a patient shows a change of ECG when presenting with chest pain, what is their diagnosis?
STEMI
27
If a patient has no ECG changes but has an increase trop level, what is their diagnosis?
NSTEMI
28
If a patient has no ECG changes or no increased trop levels, what is their diagnosis?
Unstable angina
29
Whats the difference between a STEMI and an NSTEMI in terms of the plaque?
In a STEMI the plaque has ruptured and you have irreversible necrosis of the heart. With a NSTEMI the plaque has not ruptured but it can progress to rupturing if you do not act quickly.
30
What is the best example of a nitrate used for coronary artery disease?
Glycerol Trinitrate (GTN spray)
31
Where should the patient be spraying the GTN spray and why?
Under their tongue, this is the fastest route of administration.
32
What is the MOA for GTN?
It is a vasodilator and decreases the myocardial workload
33
When would you prescribe GTN spray?
In angina and acute heart failure
34
What are the side effects of GTN spray?
Headache, hypotension, facial flushing
35
What patients shouldnt you prescribe GTN to?
Acute circulatory heart failure, head trauma, severe hypotension
36
What are the main anti-platelet drugs that are used?
Aspirin, Ticagrelor and Clopidogrel
37
How do anti-platelets work?

What are the side effects of anti-platelets?
Bronchospasm, GI bleeds, tinnitus and increased bleeding time
40
When should you not prescribe anti-platelets?
When the patient is at high risk of bleeding, if they have a low platelet count
41
Whats the loading dose of aspirin?
300mg
42
Whats the loading dose for Ticagrelor?
180mg
43
Whats the loading dose of Plasurgrel?
60mg STAT
44
How do glycoprotein 2b/3a work?

45
How would you prescribe glycoprotein 2b/3a?
Via an IV infusion
46
Why might you prescribe glycoproteins 2b/3a for patients undergoing a PCI?
They prevent any ischaemic cardiac complications
47
What are some of the side effects of glycoprotein 2b/3a?

49
How do anti-coagulant drugs work?
They prevent the blood from clotting by stopping the synthesis of clotting factors
50
What type of things would you prescribe anticoagulants for?
