Coronary Heart Syndrome Flashcards

1
Q

What is an atherosclerosis.

A

Fatty deposits (atheroma/plaques) build up on the arterial wall, causing the blood vessels to narrow, harden and eventually occlude.

Q

What is the difference between unstable angina and myocardial infarction.

A

Unstable angina is symptomatic myocardial ischemia at rest or with minimal exertion with minimal or no myocardial necrosis whereas myocardial infarction is acute myocardial injury with necrosis in a clinical setting consistent with myocardial schema.

Q

Which one is more significant ST or NSTEMI and why.

A

ST elevation MI- is generally a full or very significant artery occlusion whereas an NSTEMI is a partial ischemic occlusion off one or more coronary arteries.

Q

How is NSTEMI and ST elevation diagnosed.

A

Location is determined during angiogram or through ischemic imaging testing
ECG- guide for MI location and artery affected in ST-elevation presentation.

Q

List the diagnosis required for MI

16
Q

Patient X when he arrived to ward had normal troponin levels and 3 hours later there was rise in troponin level. How can you explain this.

A

There is a gradual release of troponin often 3-12 hours after onset of symptoms so he is in NSTEMI or STEMI. A false negative result is what happened here in this scenario.

17
Q

What is the aim in acute management when you are waiting for blood test or ECG result to ascertain whether it is NSTEMI or STEMI. Explain why each agent is given. ANPAO

A

Aim: Symptom control + Restore myocardial perfusion
High Antiplatelet loading: inhibit thrombosis formation aft6er plaque rupture.
Nitrates: Increase perfusion of myocardium by dilating the coronary venules.
Pain relief: diamorphine/morphine IV= helps heart +reduce pain.
Antisickness: for the nausea and released myocardial cells IV metoclopramide (D2 antagonist)
Oxygen: if the saturation is low.

18
Q

What is the management post diagnosis acute coronary syndrome: STEMI/NSTEMI

A

STEMI: PCI within 120 minutes or pharmacological thrombolysis within 12 hours.
NSTEMI: anticoagulation+ Antiplatelet (dual therapy)- routine elective PCI within 72 hours.

19
Q

What is Percutaneous Coronary Intervention

A
  1. Ballon catheter is inserted into the artery.
  2. The ballon is inflated to expand the stent
  3. The ballon is deflated
  4. The catheter is removed and stent remains to hold artery open.
20
Q

In STEMI early management was is the first step to manage patient pharmacological.

A

300-mg loading dose of aspirin as soon as possible and continue indefinitely.

21
Q

In early management of NSTEMI and STEMI was is the dose aspirin used.

A

300-mg loading dose of aspirin

22
Q

Please in detail provide the treatment management for STEMI

A
23
Q

Which P2Y12 inhibitor has the highest bleeding risk.
(a) Prasugrel
(b) Ticagrelor
(c) Clopidogrel

A

(a) Prasugrel then ticagrelor (b)

24
Q

Which P2Y12 inhibitor has the least bleeding risk associated.

(a) Prasugrel
(b) Ticagrelor
(c) Clopidogrel

A

(c) Clopidogrel least bleeding risk associated as second generation P2Y12 inhibitor, Prasugrel and Ticagrelor have higher bleeding risk associated as third generation P2Y12 inhibitors.

25
Q

Please in detail provide the treatment management for NSTEMI/Unstable angina

A
26
Q

If the value when using GRACE risk score to start management with angiography and Prasugrel + aspirin in NSTEMI/Unstable angina management.

A

A calculated mortality risk score of >3%.

27
Q

Please provide in detail how you manage patient after NSTEMI/STEMI/Unstable angina.

A
28
Q

Using the ABCDE acronym how should you manage patient post STEMI/NSTEMI/Unstable angina.

A
29
Q

What is the loading dose for Ticagrelor in ACS.

A

180 mg STAT

30
Q

How long can ticagrelor be used for post ACS.

A

1-3 years

31
Q

What are common adverse effects associated with ticagrelor.

A

Breathlessness and conduction disease.

32
Q

Prasugrel is contraindicated in ….

A

Stroke/TIA history or active bleed

33
Q

What are the two factors when you consider prescribing Prasugrel

A

Age (>74 years) and body weight (60 kg)

34
Q

What are common adverse drug effects associated with beta blocker.

A

Fatigue
Coldness if extremities
Hypotension
Bradycardia
Sleep disturbances

35
Q

Contraindications/Cautions with Beta blockers

A

Cardiac blocks, pronounced bradycardia, acute asthma.
