Hypertension Flashcards
What constitutes stage 1 HTN?
BP >= 140/90 mmHg in clinic and subsequent ABPM or HBPM >=135/85 mmHg
What constitutes stage 2 HTN?
BP >= 160/100 mmHg in clinic and subsequent ABPM or HBPM >=150/90 mmHg
What constitutes severe HTN?
Systolic BP >= 180 mmHg or diastolic BP >= 110 mmHg in clinic
What constitutes accelerated HTN?
Clinic BP usually >= 180/110 with signs of papilloedema and/or retinal haemorrhage.
Before the age of 65, is HTN more common in males or females?
Males
After the age of 65, is HTN more common in males or females?
Females
What is the increased percentage risk of IHD for every 2mmHg rise in BP?
7%
What percentage of HTN is primary HTN (no identifiable cause)?
90%
What drop in mmHg between clinic and home BP monitoring is sufficient to suggest a ‘white coat’ effect?
Drop of >= 20mmHg in SBP
Drop of >= 10mmHg in DBP
What signs indicate hypertensive retinopathy from fundoscopy?
Silver copper wiring, AV nipping, flame haemorrhages, cotton wool spots.
What things should be covered in the annual HTN review?
BP, , any symptoms, signs of end-organ damage/failure (eyes, heart, kidneys, liver, etc.), medication r/v including adherence and side effects, depression screen, check HbA1c and cholesterol, assess lifestyle risk factors (diet, exercise, weight, alcohol, smoking, stress).
When should anti-hypertensive medication be offered to patients?
If patient is under 80 and has stage 1 HTN AND at least one of: target organ damage, established CVD, renal disease, diabetes, Qrisk2 >= 20%.
Any patient with stage 2 or above HTN
What class of drug should be offered to white patients under 55 for HTN?
ACE inhibitor (e.g. ramipril) or, if can't tolerate dry cough, ARB.
What class of drug should be offered to over 55s or black patients of any age for HTN?
Calcium channel blocker (e.g. amlodipine)
What drug can be added if the first intensification of an ACE-inhibitor and CCB is not sufficient in controlling BP?
Thiazide-like diuretics (e.g. Indapamide)
