Q

pathophysiology of coronary heart disease

A
  • Mostly due to atherosclerotic plaques in the coronary arteries
  • Plaque breaks up inside the artery
  • = blood clot forms on the plaque surface and blocks the blood flow through the coronary artery
  • Lack of oxygen to the myocardium – sub-endocardial myocardium is initially affected
  • Myocardial necrosis

Q

RF for CHD

A
  • QRISK2 assessment (>10% is significant) – takes into account:
  • Age - risk ↑ with age
  • Sex - risk ↑ in males
  • Ethnicity – more common in Asian/African descent
  • Postcode (deprivation ↑ risk)
  • Smoking status
  • PMHx – e.g. diabetes etc.

Q

what is the diagnostic pathway for angina?

A

consider which type of angina it is - typical or atypical

if stable angina is suspected –> refer to specialist chest pain service for confirmation

if diagnosis uncertain –> 12 lead ECG

1) pathological Q wave - previous MI
2) LBBB - if new onset = MI until proven otherwise
3) STEMI or NSTEMI

associated symptoms

  • N+V
  • dizziness/syncope

Q

what needs to be included in the counselling on angina

A

factors that provoke angina - exertion, emotional stress, exposure to cold, eating a large meal

long term complication - stroke, MI, unstable angina

aim to control symptoms

how to use GTN spray/sublingual

lifestyle intervention to reduce CV risk

sexual activity - can continue, GTN helps if symptoms occur, Give 24 hours between phosphodiesterase inhibitors as contraindicated - if taken viagra - do not take GTN and rest

Q

how would you tell patients to administer GTn spray

A

• Prime: Press nozzle 5 times quickly, spraying into the air. Done the 1st time it’s used and if it has not been used in a week

1) Sit down and rest.
• 2) Remove the plastic cover and hold the bottle upright with your forefinger on top of the grooved nozzle. There is no need to shake the bottle.
• 3) Open your mouth and bring the bottle as close as possible, aiming it under your tongue.
4) Press the nozzle firmly with your forefinger to release the spray under your tongue.

DONOT inhale the spray

5 ) Release the nozzle and close your mouth. Avoid swallowing immediately after taking a dose.
• 6) For a second dose repeat the above steps.
• 7) Replace the plastic cover after use.

symptoms of a stroke

- sensory loss - paresthesia or numbness
- speech problems such as dysarthria
- homonoymous hemianopia
- Dizziness, vertigo or loss of balance
- cranial nerve deficits such as unilateral tongue weakness or Horner’s syndrome (miosis, ptosis, and facial anhidrosis).
- inattention/neglet
- confusion, altered level of consciousness and coma
- • Difficulty with fine motor coordination and gait.
• Neck or facial pain
- • Initially flacid and no reflexes then Spasticity +/- clonus, ↑ tendon reflexes

45
Q

assessment of a stroke?

A

focused Hx with pt or any witness
- time of onset, activity at onset - critical for tPA (tissue plasminogen activator)

Examin

  • A-C incl swallowing assessment
  • check BP, HR, O2, Temp
  • FAST screening – can you smile, can you raise your arms and keep them there, are you slurring your speech, time
  • check CV system for signs of heart failure, arrhythmias, murmurs, valvular heart disease, endocarditis
  • neuro exams
  • fundoscopy - look for intro-ocular haemorrhage
  • arrange ambulance to a stroke specialist unit
46
Q

what are the investigation for a stroke in a secondary care

A
  • if in ER use ROSIER score (if <0 = likely to be stroke)
  • check BM to exclude hypoglycaemia
  • ECG
  • urgent non-enhanced CT within 1 hr to differentiate between haemorrhagic or ischaemic stroke
47
Q

management of a suspected stroke in primary care

A
  • While waiting for transfer to hospital:
  • Monitor and manage ABC
  • Give O2 if sats <95%
  • If admission is not appropriate i.e. severe co-morbidities:
  • Document
  • Discuss with specialist team
  • Emergency admission to the nearest hospital with facilities for stroke thrombolysis
48
Q

management of a suspected stroke in secondary care

A

Differentiate between ischemic or hemorrhagic stroke  CT Head
• Haemorrhagic: refer to neuro
• Ischemic stroke:
• Thrombolysis with tPA (Alteplase IV) – must be given within 4.5 hours of the stroke
• Candidates have a National Institute of Health Stroke Scale score of >24
• Repeat CT head 24h later
• Mechanical thrombectomy
• Aspirin 300mg oral/rectal for 2 weeks or until discharge
• Investigate cause

49
Q

management of suspected TIA which occured within last 7 days

A

In the last 7 days/high risk:
• 300mg aspirin immediately (+PPI if appropriate)
• N/A if on 75mg aspirin already
• OR haemorrhagic risk e.g. bleeding disorder, anticoagulanted
• Urgent assessment by specialist stroke team within 24h if high risk (ABCD2 score)

50
Q

management of suspected TIA which occurred more than 7 days

A

Over 7 days ago:
• Refer for specialist assessment within 7 days
• Assess for arrhythmias i.e. AF - ABCD2 score (if > 4 = high risk)
• Give information on recognising stroke/TIA and tell them to call 999
• Advise against driving until seen by the specialist

51
Q

what are the medications used in the secondary prevention of stroke?

A

1) clopidogrel 75mg +/- aspirin 75 –> if can not tolerate both –> try modified release dipyridamole 200mg
2) Atrovastatin 80mg
3) antihypertensive eg ACEi, CCB etc
4) warfarin/NOAC - deerred start by 14 days with stroke

52
Q

what are the medications used in the secondary prevention of TIA?

A

warfarin/NOAC - can start immediately after CT head exclude hemorrhages –> also depends on CHADVAS score and HAS-BLED risk

53
Q

how would you interact with family and friends of the dying patient

A

• Offer family members and carers the opportunity for their needs (for example for support and information) to be assessed separately from those of the person receiving palliative care. They may have specific concerns such as:
o Fear of the person dying.
o Anxiety about an emergency occurring (for example what constitutes an emergency and how to deal with it).
o Feelings of inadequacy with regard to caring for the person at home (for example lack of knowledge about how to make the person comfortable or appropriate lifting techniques).
o Suppression of their true emotions in order to protect the person they are caring for.
o Financial worries.
o Altered role and lifestyle.

• Whenever possible and appropriate, invite family members and carers to be involved during clinical encounters and decisions about treatment and care (if this reflects the wishes of the person receiving palliative care).

• The family can be helped by:
o Facilitating communication between the person and their family and health care professionals.
o Recognizing areas of stress in other areas (for example work or coping with children).
o Education to provide the skills and knowledge to provide the necessary aspects of care to enhance the person’s comfort.
o Discussion of pain management to reduce anxiety regarding potential addiction or tolerance.
o Encouraging expression of fears, concerns, uncertainty, and emotional strain.
o Providing information regarding the person’s death and what to expect.

54
Q

what should be discussed during the end of life plans (Gold Standards Framework)

A
  • Preferred place of care/death
  • DNACPR
  • Escalation plan/ceiling of care
  • Social Hx i.e. friends/family, reglious needs
  • Patients wishes: will, funeral
  • Advanced care planning
  • Lasting power of attorney
  • Advance decision to refuse treatment
  • Advanced statement
  • Sorting out finances
  • Medicine review
