Q

What is stable angina

A

Where heart tissue ischaemia only occurs during exercise as the occlusion of the arteries by the atheroma only compromises the demand of the heart during this increased requirement

Q

What is a typical patient history of stable angina

A
  • chest pain when exercising
  • dull, retrosternal pain
  • no pain at rest
  • radiating pain to neck and shoulder
  • GTN spray relieves pain

21
Q

What are acute coronary syndromes

A

Problems which cause a sudden reduction in blood flow to the heart

22
Q

True or false- stable angina is an acute coronary syndrome

A

False - stable angina does not cause sudden reduction of blood flow

23
Q

How do atheromas cause acute coronary syndromes

A

The atherosclerotic plaque ruptures, platelets aggregate and a thrombus forms. This can then completely occlude the lumen.

24
Q

How much of the lumen is occluded in an STEMI resulting acute coronary syndrome

A

All of the lumen

25
Q

In unstable angina how much of the lumen is occluded

A
  • only partially occluded but there’s worsening ischaemia

- means that pain is still there at rest

26
Q

True or false - there is infarction of tissue in Non-STEMIs

A

True as there is a very small lumen

27
Q

When are cardiac enzymes released from muscle cells

A

During infarction so when the muscle cells are dead

28
Q

True or false - cardiac enzymes are released during ischaemia

A

False - only infarction

29
Q

What are the difference in the the patient history of unstable angina and stable angina

A
  • pain at rest
  • pain more intense
  • pain lasts longer
  • GTN doesn’t work
  • risk of deteriorating further to a NTSTEMI or STEMI
30
Q

Describe the patient history for a myocardial infarction

A
  • dull, retrosternal pain (more severe than angina) for more than 15 mins
  • radiates to neck and shoulders
  • looks unwell
  • increased autonomic output
  • GTN spray and resting doesn’t help
31
Q

True or false - clinical examinations for stable angina and acute coronary syndromes will always be abnormal

A

False - they are often normal

32
Q

What diagnostic tests can be done for acute coronary syndrome

A
  • ECG

- blood tests

33
Q

What are you looking for in blood tests for suspected acute coronary syndromes

A

Troponin to see if there’s myocyte death

34
Q

On an ECG what do patterns of infarct look like

A
  • ST elevation

- hyperacute T waves

35
Q

what may cause an elevated ST wave

A
  • MI

- left bundle branch block

36
Q

months after a STEMI what will the ECG have

A

prominent Q wave

37
Q

what ECG patterns are seen in ischaemia

A
  • ST depression

- T wave flattening

38
Q

how do you distinguish between a NSTEMI and unstable angina

A

troponin levels in the blood - troponin is present in NSTEMI

39
Q

what would you look at in blood tests for stable angina

A
  • FBC = looking for anaemia
  • cholesterol
  • thyroid function (hypothyroidism can cause anaemia)
40
Q

how will adenosine be used to look for ischaemia

A

adenosine causes vasodilation of the coronary arteries allowing you to see a blockage

41
Q

what medications can be used for stable angina

A
  • aspirin
  • beta blockers
  • statin
  • ACE inhibitors
42
Q

how does aspirin help in stable angina

A

anti platelet drug so prevents them sticking together

43
Q

what treatments are used for stable angina

A
  • CABG

- angioplasty

44
Q

what is the difference in occlusion of an artery of a STEMI and NSTEMI

A
STEMI = full occlusion
NSTEMI = large occlusion
45
Q

what is referred pain

A

where pain is felt away from the site of origin

46
Q

why does referred pain occur

A

the afferent signals of pain from the heart go to the brain along the same passageway as the dermatomes T1-T4. the brain then confuses the messages and presumes the pain is in the dermatomes so does this through the efferent signals

47
Q

what is radiating pain

A

when the pain starts in one place and moves around

48
Q

what is a percutaneous coronary intervention

A

a non-surgical procedure where a balloon catheter is inserted through the femoral or radial artery and is used to inflate the coronary artery. A metal stent is then added

49
Q

why is an ECG normal for someone with stable angina

A

at rest there is no significant occlusion to the blood flow so the demands of the heart are met

50
Q

what are the advantages of a coronary angiogram to a catheter angiogram

A

quicker, non-invasive and less complications
