Q

What is the pill in pocket approach?

A

In selected patients with infrequent episodes of symptomatic paroxsymal atrial fibrillation, sinus rhythm can be restored using the ‘pill in pocket approach’. This involves the patient taking oral flecinide or propafenone to self-treat an episode of AF.

Q

How should amiodarone induced hyperthyroidism be managed?

A

Thyrotoxicosis may be very refractory and amiodarone should usually be withdrawn at least temporarily to help achieve control. Treatment with carbimazole may be required

Q

How should amiodarone corneal microdeposits be managed?

A

Most patients taking amiodarone develop corneal microdeposits; these rarely interfere with vision, bu drivers may be dazzled by headlights at night. However if vision is impaired then amiodarone must be stopped to prevent blindness.

Q

Long term management following a intracerebral haemorrhage?

A

Aspirin therapy should only be given to patients at high risk of a cardiac ischaemic event.
Blood pressure should be measured and treatment initatied where appropriate, taking care to avoid hypoperfusion. Statins should be avoided following intracerbral haemorrhage, however they can be used with caution when the risk of a vascular event outweighs the risk of further haemorrhage.

Q

How long should dual AP therapy be continued following the placement of a drug eluting stent?

A

12 months
Clopidogrel should NOT be discontinued prematurely in patients with a drug-eluting stent. There is an increased risk of stent thrombosis as a result of the eluted drug slowing the re-endothelialisation process.

38
Q

What secondary prevention treatment should be considered in patients with stable angina?

A

Consider aspirin 75mg in all people with stable angina. Offer atorvastatin 80mg.

39
Q

What are the water soluble beta blockers?

A

Atenolol, sotalol, nadolol and celiprolol

40
Q

Common beta blocker side effects

A

Fatigue, coldness of extremities, and sleep disturbances. Can affect carbohydrate metabolism causing both hypo and hyperglycemia in patients with our without diabetes.

41
Q

Time of day that first dose of ramipril should be given?

A

For hypertension the first dose should preferably be given at bedtime

42
Q

A

A thiazide like diuretic - Chlortalidone and indapamide are the preferred diuretics in the management of hypertension.

43
Q

BP target in pregnancy?

A

150/90 (unless the patient has target organ damage as a result of chronic HTN, then 140/90)

44
Q

Which antihypertensive is generally first line in pregnancy?

A

Labetolol (but methyldopa or nifedipine [unlicensed] are also options

45
Q

Methyldopa should be discontinued within how many days of giving birth?

A

2 days

46
Q

What can be given to reduce BP quickly in an hypertensive crisis?

A

IV sodium nitroprusside, nicardipine labetolol are all options

47
Q

Outline the management of phaeochromocytoma?

A

Long term management involves surgery

Give an alpha blocker for short term management of hypertensive episodes

48
Q

Why are ARBs a suitable alternative for someone experiencing a cough with an ACEi?

A

ARBs do not inhibit the breakdown of bradykinin

49
Q

What kind of drug is aliskren?

A

Renin inhibitor

50
Q

What is the recommendation about combining ACEi/ARB or aliskren?

A

Combination is not advised due to increased risk of hyperkalemia, hypotension and renal impairment

51
Q

What is meant by instrinsic sympathomimetic activity (ISA) in terms of beta blockers?

A

Capacity of a BB to stimulate as well as block receptors

52
Q

What is the advantage of BB that have less intrinsic sympathomimetic activity?

A

Tend to cause less bradycardia and less coldness of the extremeties

53
Q

What are the water soluble beta blockers? (hint: SCAN)

A

Sotalol
Carvedilol
Atenolol
Nadolol

54
Q

Why might a water soluble BB be beneficial?

A

Less able to cross the BBB and cause sleep disturbances

55
Q

What are the cardioselective beta blockers?

A

Atenolol
Bisoprolol
Metoprolol
Nebivolol

56
Q

Why should BB be avoided in combination with a thiazide diuretic in patients with diabetes?

A

BB can cause both hyper and hypo glycemia
BB can mask the symptoms of hypos
Thiazides can cause hyperglycemia and therefore exacerbate diabetes

57
Q

How is a beta blocker overdose treated?

A

Atropine (to reverse bradycardia)

if ineffective can give glucagon

58
Q

Which beta blockers are worse in breast feeding?

A

Water soluble beta blockers are present in breast milk in greater amounts that other BB

59
Q

When using beta blockers in heart failure, what must you ensure before adding in a beta blocker or increasing the dose?

A

Ensuring the heart failure is stable and not worsening.

60
Q

Ramipril in hepatic impairment

A

Ramipril is a prodrug so requires good renal function. Max 2.5mg in hepatic impairment

61
Q

What agents can be used to manage hypotension and shock?

A

Correct volume and can use sympathomimetic inotropes such as adrenaline, epinephrine and dobutamine

62
Q

What is the indication of eplenerone?

A

Can be used in patients with LVSD following an MI

63
Q

What patient groups require primary prevention of CVD with a statin?

A

Diabetics, CKD, FHx of hypercholesterolaemia and if QRISK >10%

64
Q

Hypothyroidism can increase plasma lipid levels. What action should be taken in this case?

A

Patients with hypothyroidism should receive levothyroxine as this may correct lipid levels before assessing the need for a statin.
Also - untreated hypothyroidism increases the risk of myositis with statins.

65
Q

Statin monitoring

A

Baseline total cholesterol, HDL-cholesterol and non-HDHL after 3 months. Aim for a 40% reduction in non-HDL.
LFTs baseline, 3 months and after 12 months.
CK baseline
If diabetic - HbA1c baseline

66
Q

1st line treatment for stable angina

A

CCB or a BB

67
Q

2nd line treatment for stable angina

A

CCB and a BB

68

Ivabradine is contraindicated with what 3 drugs?

A

Diltiazem, erythromycin and verapamil
