Q

Unstable angina, myocardial infarction and ischaemic stroke can all result due to which plaque build up?

A

Unstable Plaque

18
Q

How would you investigate Atherosclerosis? (3)

A
  • CT angiography
  • Blood tests
  • Catether-based imaging tests
19
Q

What is Angina?

A

Chest pains due to the heart not getting enough oxygen (ischemia) due to narrowed arteries

20
Q

Describe stable angina

A
  • Predictable

- Increased workload leads to ischaemia

21
Q

Where can symptoms of angina radiate to? (6)

A
  • Left shoulder
  • Inside left arm
  • Back
  • Throat
  • Jaw
  • Teeth
22
Q

How would you investigate Angina? (3)

A
  • ECG
  • Coronary artery angiography
  • Intravascular ultrasonography
23
Q

What is a myocardial infarction

A

Myocardial necrosis (tissue death) resulting from acute obstruction of a coronary artery

24
Q

How can you temporarily relieve a myocardial infarction?

A

Rest or glyceryl trinitrate

25
Q

What is infective endocarditis?

A

Rare condition associated with microbial infection of the endocardial surface of the heart (heart valves)

26
Q

What increases the risk of infective endocarditis? (4)

A
  • Prosthetic valves
  • Previous Infective endocarditis
  • Acquired valvular heart disease
  • Congenital heart defect
27
Q

How long does acute bacterial endocarditis take to occur?

A

Within 7 days of infection

28
Q

How long does sub-acute bacterial endocarditis take to occur?

A

Tooth brushing and chewing

34
Q

How can patients at risk of infective endocarditis reduce chance of infection? (4)

A
  • Maintain good oral health
  • Receive intensive preventative oral healthcare
  • Informed of risks
  • Made aware of symptoms
