1

Differentiate the site of radiation in MI vs aortic dissection

MI: jaw
AD: back

2

What are the typical associated symptoms of cardiac-origin chest pain?

Nausea
Sweating

3

Describe the location of pneumonia-related chest pain

Pleuritic

4

Describe the location of pain caused by costochondritis

Gives a localised tenderness

5

Recall one exacerbating and one alleviating factor for pericarditis chest pain

Exacerbating: inhalation
Alleviating: leaning forwards

6

Cardiac-origin chest pain with flu-like symptoms is most likely to be due to what?

Pericarditis

7

Recall one key sign in pericarditis

Pericardial friction rub

8

Which drugs should be given in any MI (STEMI or NSTEMI)?

Aspirin
Clopidogrel

9

What is a PCI?

Percutaneous coronary intervention: an angioplasty with a stent

10

Recall the 1st, 2nd and 3rd-line investigations in suspected MI

1. ECG
2. Troponin (result indicates 4th-line)
3. Echo

11

What investigation should be carried out if troponin is positive in a suspected MI?

Coronary angiography

12

What investigation should be carried out if troponin is negative in a suspected MI?

Exercise tolerance test

13

What information does troponin give in a suspected MI?

If positive suggests STEMI - as there has been muscle death
If negative suggests NSTEMI as there is less ischaemic damage resulting from partial coronary arterial occlusion

14

What will be seen on echo if there has been an MI?

Regional Wall Motion Abnormality due to death of that region of cardiac muscle

15

Recall 3 cardiac differentials for chest pain

1. IHD
2. Aortic dissection
3. Pericarditis

16

Recall 4 respiratory differentials for chest pain

1. PE
2. Pneumothorax
3. Pneumonia
4. Pleuritic pain caused by connective tissue disease

17

In a suspected aortic dissection, what 2 things would you find on examination that were abnormal?

1. Aortic regurgitation can be auscultated when they lean forwards
2. BP difference between arms

18

What is the characteristic appearance of pericarditis on ECG?

Widespread saddle-shaped ST elevation

19

Recall 3 GI differentials for chest pain

1. Oesophageal spasm
2. Gastritis/oesophagitis
3. Oesophageal candidiasis

20

Recall 2 groups of people who are at high risk of oesophageal candidiasis

1. Those on immunosuppressant medication
2. Those on steroid medication eg. dexamethosone (due to its immunosuppressive effect)

21

Recall a musculoskeletal differential for chest pain

Costochondritis

22

Recall 3 exacerbating factors for costochondritis chest pain

Exercise
Posture
Deep breath/ sneeze

23

In which leads is ST elevation seen in an anteriolateral STEMI?

I, aVL, V2-V6

24

In which leads is ST elevation seen in an inferior STEMI?

II, III, aVF

25

Occlusion of which coronary artery causes an anterior MI?

LAD

26

In which leads is ST elevation seen in an anterior STEMI?

V1-V4

27

In which leads is ST elevation seen in a lateral MI?

I, aVL, V5, V6

28

Occlusion of which coronary artery causes a lateral MI?

Circumflex

29

Occlusion of which coronary artery causes an inferior MI?

Right coronary artery
