Q

Describe what elements of a chest pain Hx indicate specific causes?

A
  • Acute onset, with central/band-like pain which radiates to the person’s jaw, arms, or back –> cardiac
  • Persistent, localised pain –> pulmonary / MSK
  • Exertional chest pain –> angina
  • Pleuritic chest pain –> pulmonary / MSK
  • Breathlessness –> cardiac / pulmonary
  • Associated with palpitations, dizziness, or difficulty swallowing is less likely to be angina
  • Do not rule out stable angina on the basis of a normal resting 12-lead ECG
  • An abnormal ECG makes the diagnosis of CAD more likely
  • A recent normal coronary angiogram excludes CAD
  • Stable angina or MI –> assess for CV risk factor (older age, male, smoking, HTN, DM, increased cholesterols, FHx CVD)
  • Previous chest trauma- MSK, GI
  • Anxiety/depression –> psychogenic or non-specific chest pain

Q

Describe the examination you’d preform for chest pain?

A
  • CV exam: Heart sounds (murmurs/pericardial rub), BP both arms (aortic dissection), pulse rate and rhythm (shock / arrhythmias), JVP, carotid pulse, ankles (oedema –> HF)
  • Chest wall: palpate for tenderness, assess whether movement of the chest wall reproduces the pain (MSK), listen to lung fields (infection),
    RR and pulse oximetry (low O2 sat)
  • General appearance: pallor and sweating (shock)
  • Abdomen: tenderness (gallstones, pancreatitis, or peptic ulceration)
  • Neck: localised tenderness and stiffness (cervical spondylosis or OA)
  • Legs: swelling or tenderness (DVT)
  • Skin: rashes (shingles) and bruising (rib fracture)

  2. Persistent AF- episodes lasting >7 days (spontaneous termination is unlikely to occur after this time) or <7days but requiring pharmacological or electrical cardioversion
  3. Permanent AF- fails to terminate using cardioversion, AF that is terminated but relapses within 24 hours, or longstanding AF (usually >1 year) which cardioversion has not been indicated or attempted
59
Q

  • PMHx: cardiac disease &/or recent cardiothoracic surgery. Diabetes, thyroid disease, cancer, alcohol misuse.
  • Suspect Paroxysmal AF if Sx are episodic and last <48hrs
  • ECG: no P-waves, chaotic baseline, irregular ventricular rate (160-180bpm)
  • If paroxysmal AF is suspected & AF is not seen on ECG: 24hr ambulatory ECG monitor or 7-day Holter monitor
60
Q

How would you manage AF if the onset was within the last 48hrs?

A
  • Urgently admit for emergency cardioversion if the person has signs and Sx of haemodynamic instability, such as a rapid pulse (>150bpm) and/or low BP (SBP <90 mmHg), loss of consciousness, severe dizziness/syncope, ongoing chest pain, or increasing breathlessness
  • If not exhibiting signs of haemodynamic instability, consider management in primary care (if appropriate) or refer the person to an acute medical unit for immediate cardioversion, depending on preferences and clinical judgement

63
Q

Describe the follow up care for AF?

A
  • Within 1wk of starting rate-control (or any dose alteration), check tolerating the drug, and review Sx (palpitations, breathlessness, fatigue), HR, and BP
  • For people taking warfarin anticoag assess INR initially daily until within therapeutic range on 2 occasions (2-3), then monitor 2x weekly for 1-2weeks, then weekly, thereafter if stable monitor at longer intervals
  • Calculate time in therapeutic range (TTR) at each subsequent visit to ensure maintenance of international normalized ratio (INR) between 2-3 over a longer period of time
  • Poor anticoag control= TTR <65%, 2 INRs >5 or 1 INR >8 within past 6m, 2 INRs <1.5 within past 6m
  • If poor anticoag control cannot be improved, consider switching to DOAC (apixaban, edoxaban, dabigatran or rivaroxaban)
  • Review at least annually once Sx controlled

Q

List 10 contraindications for calcium channel blockers (Diltiazem, Verapamil)?

A
  1. LVF with pulmonary congestion
  2. Severe bradycardia (<40/50bpm)
  3. 2nd/3rd degree AV block except with functioning ventricular pacemaker - as Ca-channel blockers may induce AV block
  4. Severe hypotension (SBP <90bpm)
  5. Severe aortic stenosis
  6. Cardiogenic shock
  7. Congestive HF
  8. Sick sinus syndrome
  9. People taking ivabradine
  10. Pregnancy
65
Q

List the 5 indications when you wouldn’t prescribe digoxin?

A
  1. Some supraventricular arrhythmias (Wolff–Parkinson–White syndrome)
  2. Arrhythmias caused by previous digoxin/another cardiac glycoside
  3. Heart conduction problems (intermittent complete heart block/AV heart block)
  4. Ventricular tachycardia/ventricular fibrillation
  5. Hypertrophic obstructive cardiomyopathy, unless concomitant AF and HF
66
Q

List the 3 types of adverse effects of digoxin?

A
  1. Cardiac: sinoatrial and atrioventricular block, premature ventricular contractions, PR prolongation and ST-segment depression
  2. Non-cardiac: N&V, visual abnormalities, CNS effects, thrombocytopenia, gynaecomastia
  3. Narrow therapeutic window of Digoxin
67
Q

List the 5 advantages and disadvantages of warfarin and DOACs?

A
  1. Stroke risk reduction: DOACs & warfarin the same
  2. Risks: DOACs associated with a reduced risk of haemorrhagic stroke & intracerebral haemorrhage
  3. Adherence: adherence is vital, more important with the NOACs. Because DOACs have a relatively short half-life & anticoag effect fades rapidly after 12-24hrs. With warfarin, some benefit is retained for 48-72 hours after missing a dose
  4. Monitoring: DOACs have predictable pharmacokinetics, so coag control does not need to be monitored. Warfarin, needs regular blood tests
  5. Reversibility: unlike warfarin, there are, as yet, no specific antidotes for DOACs
68
Q

What would you prescribe for follow up treatment of AF if anticoagulation was contraindicated?

A

Combination of aspirin and clopidogrel

69
Q

Describe how amiodarone would be given and monitored?

A
  • Always initiated in secondary care

- Baseline assessments are performed beforehand: TFTs, LFTs, serum U&Es, chest radiography and electrocardiography

70
Q

List the 6 complications of chronic heart failure?

A
  1. Arrhythmia
  2. Depression
  3. Cachexia
  4. Chronic kidney disease
  5. Sexual dysfunction
  6. Sudden cardiac death
71
Q

What should you do in GP if chronic heart failure is suspected?

A
  • Serum natriuretic peptide level (NT-proBNP) measured
  • If level is normal, HF is unlikely
  • If levels are raised, referral for specialist assessment & echocardiography
  • 12-lead ECG to exclude aggravating factors
  • Loop diuretic may be prescribed for Sx relief while awaiting specialist assessment
72
Q

What should you do for confirmed HF with reduced ejection fraction?

A
  • Diuretic: relieve Sx of fluid overload
  • Angiotensin-converting enzyme (ACE) inhibitor & a beta-blocker should be prescribed: reduce morbidity and mortality
  • If still symptomatic despite optimal treatment with an ACEi & beta-blocker, a referral for specialist management
73
Q

List the 9 things that you should do for all people with confirmed HF?

A
  1. Prescribe an antiplatelet & statin should be considered
  2. Comorbidities & precipitating factors should be managed
  3. Screening for depression/anxiety
  4. A supervised exercise-based rehabilitation programme offered
  5. Appropriate vaccinations offered
  6. Self-care advice
  7. Nutritional status assessed
  8. Follow-up & advanced care planning offered, if appropriate
  9. Women of child-bearing age should be given advice about contraception & pregnancy
74
Q

What is the definition of heart failure?

A

The ability of the heart to maintain the circulation of blood is impaired as a result of a structural/functional impairment of ventricular filling/ejection

75
Q

Describe the 3 different ways chronic heart failure can be classified according to?

A
  1. Ejection Fraction: reduced LVEF =/< 35-40% (HF-REF). Or there is preserved EJ (HF-PEF)
  2. Time-course: acute HF may be a new presentation/deterioration or decompensation of chronic HF. Or chronic HF which there is no agreed definition of timescale
  3. Symptomatic severity: New York heart association (NYHA)
76
Q

Describe the 4 functional classification of HF according to the New York heart association (NYHA)?

A
  1. Class I: no limitation of physical activity. No undue fatigue, breathlessness, or palpitations
  2. Class II: slight limitation of physical activity. Comfortable at rest but ordinary physical activity results in undue breathlessness, fatigue, or palpitations
  3. Class III: marked limitation of physical activity. Comfortable at rest but less than ordinary physical activity results in undue breathlessness, fatigue, or palpitations
  4. Class IV: unable to carry out any physical activity without discomfort. Sx at rest can be present
77
Q

Describe the other types of HF?

A
  • Right heart failure & left heart failure were used to reflect whether the predominant symptoms reflected congestion in the systemic (right) or pulmonary (left) veins
  • Congestive heart failure describes evidence of sodium & water retention
78
Q

List the 9 types of causes for chronic heart failure?

A
  1. Myocardial disease: CAD (most common), HTN, cardiomyopathies
  2. Valvular heart disease: AS
  3. Pericardial disease: constrictive pericarditis, pericardial effusion
  4. Congenital heart disease
  5. Arrhythmias: AF
  6. High output states: anaemia, thyrotoxicosis, phaeochromocytoma, septicaemia, liver failure,
    AV-shunts, Paget’s disease, Thiamine (vitamin B1) deficiency
  7. Volume overload: end-stage chronic kidney disease, nephrotic syndrome
  8. Obesity
  9. Drugs: alcohol, cocaine, NSAIDS, beta-blockers and calcium-channel blockers
