Hypertension

Dr Som Desilva

Page 2: Primary care team meeting

What do we need to discuss?

• Managing hypertension in surgery• New guidance on diagnosis• Home BP vs ABP• When and what investigations are needed• What drug treatments and who should titrate

Page 3: Primary care team meeting

Also

• What is best way for titration to take place• If any problems who should Nurse or HCA go

to • Monitoring of hypertension

• Long term care planning - update

Page 4: Primary care team meeting

New changes from NICE

• Ambulatory blood Ambulatory blood pressure is suggested as the investigation of choice for all with suspected hypertension.

• Home readings Home readings are an alternative, if ambulatory cannot be used.

• Clinic BP readings are no longer recommended for the diagnosis of hypertension, however they can (and should) be used to monitor responsesresponses to treatment.

Page 5: Primary care team meeting

Hypertension is now defined as

This affects who we treat.

• Stage 1 hypertension - Think of it as borderline hypertension on ABPM – BP 135-149/85-94 treat only if 10y CVD risk >20% or end organ damage (fundoscopy/ecg/renal)

• Stage 2 hypertension - >150/95 – Offer treatment straight away.

What BP should we worry about?

• IF BP

• Repeat during consultation.• If 2nd reading substantially different from 1st,

take a 3rd reading.• Record the lowerlower of the last 2 readings. IF still

high then arrange 24h BP or home BP monitor

IN CLINICIN CLINIC

Page 8: Primary care team meeting

What if BP very high?

• When lower of 3 readings of BP >>

• ?accelerated hypertension – should consider immediate drug treatment with out waiting for results of home bp/24h bp

• Should speak to on-call GP

Page 9: Primary care team meeting

What’s treatment?

• Lifestyle advice to all – DIET, SMOKING, ALCOHOL & CAFFEINE, EXERCISE

• DRUG TREATMENT

Page 10: Primary care team meeting

WHAT INVESTIGATIONS?

• OnceOnce diagnosis has been established• ECG• Bloods –Nice recommends FBC U+E RBS eGFR

Total cholesterol&HDL• ACR• Dipstick urine for haematuria• Fundoscopy

Page 11: Primary care team meeting

I would recommend

• TFT TFT - thyroxicosis rare but can cause elevated bp – esp if there is little variation in day and night time blood pressure – (bp is being driven along by secondary cause)

• In younger pts -> ie less than 50 consider:Renal U/S Renal U/S with renal artery calibre (NOT BEST

FOR RAS BT EASIER THAN RENAL MRA)24h Urine for catecholamines24h Urine for catecholamines

Page 12: Primary care team meeting

10Y of CARDIOLOGY

• NEVER FOUND A PHEO – but still looking!!!!• 2 THYROTOXIC PATIENTS• 2 LUNG CANCERS• 3 RENAL TUMOURS• 1 HYDRONEPHROSIS• 1 SECONDARY ADRENAL TUMOUR

Page 13: Primary care team meeting

How to do ABPM

• Ambulatory BP readings (ABPMAmbulatory BP readings (ABPM)• Use a device that measures at least 2

measurements/hour during waking hours.• You need to have at least 14 readings to

average.• In the past we added 10/5 to ABPM before

making decisions – there is no need to do this now, since the decision flow charts are based on ABPM not clinic readings.

Page 14: Primary care team meeting

How to do Home BP monitor

• Home BP monitoring (HBPM)Home BP monitoring (HBPM)• Take readings morning & evening for at least

4d, preferably 7d.• On each occasion take 2 readings ≥1min apart,

whilst seated.• Discard the first day’s readings, and average

the remaining readings.

Page 15: Primary care team meeting

What drugs

• Depends on age and ethnicity• Ace-I >> CCB >> ACE+CCB >>diuretic >> Alpha

blocker >> beta blocker >>ARB if not already on >> Methyl dopa

Page 17: Primary care team meeting

When should we titrate up drugs?• Use clinic BP readings to monitor response to treatment.

• Ambulatory/home readings can be used in those with known ‘white coat’ hypertension (defined as a discrepancy of >20/10 between clinic and average ambulatory or home readings at time of diagnosis).

• Increase drug therapy if these targets are not achieved.• Aim for:• Clinic BP readings of: Ambulatory/home average readings of:• <80y <140/90<80y <140/90 <80y <135/85 <80y <135/85• >80y <150/90 >80y <145/85

Page 18: Primary care team meeting

So who and what do we organise?

HCAnurse

Suspected bp Arrange home/abpm

GP s

Results –who looks at them

Confirms diag

Start treatment

Investigations – ecg and bloods etc

Monitor bp

Up titrate bpWhen stable- 9m fu in bp clinic

Page 19: Primary care team meeting

management

• What we don’t want is hypertensive patients taking up gp appts for confirmation of diagnosis and titration!

• Or do we want pts coming to gp at diagnosis to confirm/agree a management plan – monitored by HCA or nurse over next 6m??

Page 20: Primary care team meeting

Discuss??

• What about the other clinics – CD clinics now filled up with mixture of diseaseS on different days

• DIAB – BE /DJ - try and find Som during week• What about COPD/ASTHMA/IHD/STROKE• HOW ABOUT A GP OF THE WEEK??• QUERY GOES TO ON CALL GP• GOOD TO SORT OUT WHILE PT IN BUILDING
