What management should a patient with pre-existing angina be given when undergoing an angina attack?
How can chest pain be classified?
- Cause: cardiac/non cardiac
- Type: localised/poorly localised and pleuritic or non-pleuritic
How should you investigate and manage a patient with acute chest pain?
- Full CVS exam
- ECG 12 lead
- Cardiac enzymes/troponin
- Call 999 if urgent admission needed
If a patient presents with chest pain and does not require an immediate admission, where should they be referred to?
REFER TO CHEST PAIN CLINIC
- Urgent same day assessment: if suspected ACS but pain-free with chest pain in the past 12 hours and a normal ECG or chest-pain in past 12-72 hours with no complications
- 2 Weeks: suspected ACS with pain in past 72 hours, suspected malignancy, suspected pleural effusion, suspected lobar/lung collapse
- Routinely if stable angina or unknown chest pain
What should you do if you suspect a patients pain is due to ACS?
- Call 999
- Aspirin 300mg PO single loading dose chewed as antiplatelet
- Give clopidogrel 300mg PO loading
- Maintain sats >94% using oxygen if pulmonary oedema or hypoxia
- Offer morphine and antiemetics to relieve ischaemic pain
What signs associated with acute chest pain should encorage you to admit a patient to hospital urgently?
- Resp rate >30
- Tachycardia >130
- BP <90 <60 unless normal
- Temp >38.5
- Sats <92% or central cyanosis
Where do patients with suspected STEMIs go when they get to the hospital?
If had an ECG in the ambulance they go straight to the cardiology catheter lab
How should you manage a patient in primary care that presents with a suspected PE?
- Immediate admission for anyone who is haemodynamically unstable or pregnant/given birth in past 6 weeks
- If none of these then do the Well’s criteria. If >4 admit to hospital for CTPA, if <4 offer D-dimer test with result in 4 hours with interim anticoagulation if takes longer. If test positive send for CTPA
What interim anticoagulation is given whilst awaiting results of a D-dimer test for a likely PE?
- Take FBC, renal and hepatic function, PT and APTT before commencing but do not wait for results
- Apixiban or Rivaroxiban first line for at least 5 days
- If not suitable use LMWH followed by dabigatran for 5 days OR LMWH with Vit K antagonist for 5 days
What are some differential diagnoses for acute shortness of breath in primary care?
- Silent MI
- Cardiac arrhythmia
- Acute pulmonary oedema/heart failure
- COPD
- Asthma
- Pneumona

- Diaphragmatic splinting
- Psychogenic breathlessness
What are some questions you would ask a patient presenting with an acute presentation of SOB?
- B.P
- Pulse
- Resp rate
- Sats
- ECG
- PEFR
- Temperature
What features would warrant an admission to hospital when a patient presents to primary care with SOB?
- If sats less than 94% oxygen should be given and monitored while awaiting transfer to hospital, unless at risk of hypercapnia
- Only admit chronic breathlessness, e.g COPD, if exacerbation
What would define whether asthma is severe asthma and life threatening asthma?
What is the management for acute asthma?
OSHIT
- O2 5l to maintain sats between 94-98%

- IV hydrocortisone 100mg or 40-50mg PO prednisolone
- Add ipratropium bromide 0.5mg/6h to nebuliser is life threatening
- Magnesium sulfate and theophylline added by specialists
If life threatening hospital admission, if improved 24 hour follow up
How do you manage an acute exacerbaton of COPD?
How do you manage a suspected TIA?
- Give aspirin 300mg unless contraindicated or taking aspirin regularly
- Arrange assessment by TIA clinc within 24 hours if TIA occured in last week, if more than a week ago refer to specialist within 7 cays
- Arrange urgent admission if patient has had more than one TIA, if patient lacks reliable observer at home or if patient has bleeding disorder/taking anticoagulant

- Stroke often can wrinkle forehead as central lesion but cannot in Bell’s
- Bell’s will have absence of other neurological symptoms
How would you manage Bell’s palsy in primary care?
- If presenting within 72 hours of onset prescribe prednisolone 50mg for 10 days

- Use straw
- Refer to facial nerve specialist if no improvement after 3 weeks of treatment or incomplete recovery in 5 months
When should you refer someone with Bell’s Palsy urgently to secondary care?
Should be no hearing loss with Bell’s
How would you treat anaphylaxis once specialist help has arrived?
- Constantly monitor pulse, sats, bp and ECG
- Establish airway
- IV fluid challenge with 500ml 0.9% saline in 5-10 minutes if normotensive, 1000ml if hypotensive
- Chlorphenamine
- Hydrocortisone
- If still breathing difficulty give IV or inhaled bronchodilators etc
