Q

When do you treat stage 1 and stage 2 HTN?
What age should you consider specialist referral?

A

Stage 1 Rx if <80yo only treat medically if: diabetic, renal disease, QRISK2 >10%, established coronary vascular disease, or end organ damage. Otherwise lifestyle.

Consider if under 60 with stage 1 HTN and QRISK <10%

Stage 2 - everyone

For patients < 40 years consider specialist referral to exclude secondary causes.

Q

Treatment of HTN

A

<55yo or diabetic: A –> A+C or A+D

> 55 and not diabetic, or black: C –> C+A or C+D

Third line A+C+D
(D indapamide or chlortalidone may be preferred over bendroflumethiazide)

Step 4 <=4.5 –> spiro >4.5 alpha blocker or BB

If not controlled on four drugs then refer to secondary care.

digoxin
for symptomatic relief and is strongly indicated if there is coexistent atrial fibrillation

28
Q

If BP >180/120 but no eye signs of life threatening sx then what investigations would you request? (3)

When would you start BP meds without waiting for the results of ABPM or HBPM?

What would you do if that is not the case?

A

bloods, urine ACR, ECG

If end organ damage

Repeat clinic blood pressure measurement within 7 days

29
Q

What is ambulatory blood pressure monitoring (ABPM)?

A

at least 2 measurements per hour during the person’s usual waking hours (for example, between 08:00 and 22:00)
use the average value of at least 14 measurements

30
Q

What is home blood pressure monitoring (HBPM)?

A

for each BP recording, two consecutive measurements need to be taken, at least 1 minute apart and with the person seated
BP should be recorded twice daily, ideally in the morning and evening
BP should be recorded for at least 4 days, ideally for 7 days
discard the measurements taken on the first day and use the average value of all the remaining measurements

(not the details)

A

<48 hours of symptoms (and haemodynamically unstable) OR have been anticoagulated for a period of time prior to attempting cardioversion

(previously HASBLED)

Age >75 (1)
Bleeding hx (2)
Renal impairment (1)
Tx with antiplatelet agents (1)

0-2 - low risk

40
Q

Cardioversion Mx
<48 hours
Give ? and then can electrocardiovert
How long should you anticoagulate for after this?
OR
Pharmacological - structural (1)/ non structural (2)

> 48 hours
anticoag for ? weeks
OR
? then ?+?

If high risk of cardioversion failure then give ? or ? for ? weeks prior to cardioversion

How long should you anticoagulate for following this

A

<48 hours
- heparinised
- electrical DC cardioversion - if this then further anticoagulation is unnecessary.

OR
- pharmacological with amiodarone if has structural heart disease. OR flecainide or amiodarone if no structural heart disease.

> 48 hours
- anticoagulate for 4 weeks prior
OR
- TOE to exclude thrombus and then can be heparinised and cardioverted immediately.

  • electrical cardioversion rather than pharmacological.
    If high risk of cardioversion failure (previous failure or recurrence of AF) then to have 4 weeks or amiodarone or sotalol prior to electrical cardioversion.
  • 4 weeks minimum of anticoagulation following this.
41
Q

Anticoagulation of choice if a pt develops a stroke/ TIA with AF

When do you start anticoag in acute stroke patients?

A

Warfarin - anticoag of choice

In acute stroke patients, in the absence of haemorrhage, anticoag therapy should be commenced after 2 weeks.

42
Q

When to use digoxin in AF?

A

only be considered if the pt does no or very little exercise as is no as good at controlling HR during exercise.

43
Q

Catheter ablation
When is it used?
When to anticoagulate?

Complications (3)

A

For those with AF who have not responded to or wish to avoid, anti-arrhythmic medication

4 weeks before and after
