What are the (i) investigations and (ii) management for someone with suspected stable angina?
(i) ECG - usually normal but may show past MI
Exclude precipitating factors = anaemia, DM, thyrotoxicosis, hyperlipidaemia, temporal arteritis
(ii) 1. Modify risk factors = smoking, exercise, weight loss. If cholesterol greater than 4 prescribe statin
2. GTN spray
3. Aspirin 75-150mg/day
4. b-blockers (ivabradine if cannot tolerate)
What are the investigations for someone with suspected ACS?
1) ECG: within hours = tall T waves, ST elevation or new LBBB. Within days = T wave inversion, pathological Q waves
2) CXR = cardiomegaly, pulmonary oedema, widened mediastinum
3) Troponin T+I = rise within 3-12hrs and peaks at 24-48hrs
How do you treat a STEMI?
FIRST = MONAC - morphine + metclopramide - if sats less than 90% give oxygen - IV nitrates - Aspirin - clopidogrel Then 1) Primary angioplasty OR thrombolysis with alteplase 2) IV b-blocker (atenolol) 3) ACEi (lisinopril) 4) clopidogrel 300mg loading dose followed by 75mg/day for 30 days Review at 5 wks and 3 months post MI
How do you treat an NSTEMI?
1) if sats less than 90% give oxygen
2) IV morphine + metclopramide
3) Nitrates (IV/PO)
4) Aspirin lifelong (lose if low GRACE score) + clopidogrel (12 months)
5) Antithombotic fondaparinux if low bleeding + no angioplasty planned
6) b-blocker
7) ACEi
8) statin + address modifiable risk factors e.g. smoking, exercise, DM, HTN, hyperlipidaemia
Review at 5 wks and 3 months post MI
What are the investigations for someone with suspected Heart Failure?
BNP - raised
CXR - alveolar oedema, kerley B lines, cardiomegaly, dilated prominent upper lobe vessels, pleural effusion
ECG - determine cause and degree of LV function
Diagnose using Framingham criteria and classify based on NYHA classification
What is the management for someone with heart failure?
Stop smoking, eat less salt, optimise weight and nutrition
Then treat cause. Treat exacerbating factors (anaemia, thyroid, infection, HTN) and avoid drugs that can exacerbate (NSAIDs, verapimil)
1. Loop diuretics e.g. furosemide
2. ACEi/ARB
3. B blocker
4. Spironolactone
5. Digoxin (if in AF and have HF)
6. Vasodilators (hydralazine and isosorbide dinitrate) if intolerant to ACEi/ARB or used in standard therapy for patients of black ethnic origin
What are the (i) investigations and (ii) management for someone with suspected atrial fibrillation?
(i) ECG = irregular QRS, absent P waves
Bloods = U+E, cardiac enzymes (trops), TFTs
(ii)
ACUTE AF (less than 48h)
- O2, U+E, emergency DC cardioversion (if unavailable then amiodarone IV)
- treat associated illness
- control rate (1st line = verapimil or bisoprolol
- anticoagulate with LMWH
CHRONIC AF (prioritise rate control + anticoag)
- anticoagulation = warfarin, aspirin, dabigatran
- rate control = b-block or verapimil or diltiazem
PAROXYSMAL AF = flecainide ‘pill in pocket’
What are the (i) investigations and (ii) management for someone with suspected infective endocarditis?
(i) blood cultures - 3 separate occasions
bloods - normocytic normochromic anaemia
urinalysis - microscopic haematuria
ECG - prolonged PR interval/complete AV block
Echo = vegetations
Use DUKE’s criteria for diagnosis
(ii) Antibiotics (amoxicillin +- vancomycin/gentamicin)
Consider surgery.
Dental and oral hygiene is important
What are the 3 stages of hypertension?
- clinic BP over 140/90 or ABPM over 135/85
- clinic BP over 160/100 or ABPM over 150/95
- clinic: diastolic over 110 or systolic over 180
What is the management for hypertension?
UNDER 55:
ACEi - ACEi+CCB or ACEi+diuretic, then ACEi+CCB+diuretic
- add further diuretic/alpha blocker/beta blocker
OVER 55 or black ethnicity:
CCB/diuretic - ACEi+CCB or ACEi+diuretic - ACEi+CCB+diuretic
- add further diuretic therapy/alpha blocker/beta blocker
What are the investigations involved in severe pulmonary oedema?
CXR = cardiomegaly, ‘bat wings’, effusion and kerley B lines
ECG = signs of MI, dysarrhythmias
U+E, troponins, ABG, plasma BNP
Consider ECHO
What is the management in severe pulmonary oedema?
- sit patient UPRIGHT
- oxygen 100% if no pre-existing lung disease
- IV access and ECG
- Diamorphine IV
- Furosemide IV
- GTN spray
- If SBP over 100mmHg start a nitrate infusion (isosorbide nitrate). If sys is under 100mmHg, treat as cardiogenic shock
What are the investigations involved in suspected pneumonia?
CXR
Oxygen sats + BP plus maybe ABGs
Bloods = U+E, FBC (leucocytosis), LFT, CRP
Blood culture
Sputum culture
Urine anitgen testing for legionella and pneumococcus
What is the criteria of the CURB-65 score? How is it used to base treatment of pneumonia?
Confusion
Urea over 7mmol
Resp rate over 30 breaths/min
BP sys under 90mmHg or diastolic under 60mmHg
Aged over 65
0-1 = home treatment (mild) with amoxicillin or clarithromycin
2 = amoxicillin and clarithromycin
3-5 = severe, co-amoxyclav and clarithromycin
- consider oxygen and fluids, plus VTE prophylaxis
- analgesia if in pleuritic pain
