Chapter 4: Hypertension Flashcards
Hypertension is a major risk factor for Stroke, Myocardial infarction, heart failure, chronic kidney disease, cognitive decline, and premature death. List the causes of hypertension.
- Increased age,
- Ethnicity (black afro-Caribbean)
- Male
- Family history
- Diet (salt intake, High cholesterol, less fruits consumed)
- Reduced physical activity
- Obesity
- Medications (antidepressants, antidiabetics)
- Smoking
- Social deprivation
- Lifestyle factors (Stress, Anxiety )
What advice could you give to patients with hypertension?
- Benefits of regular exercise (150mins moderate exercise / 75 mins vigorous exercise).
- Healthy diet
- Low sodium intake (6g/day = 1 tsp)
- Reduced alcohol intake (<14 units /wk)
- Discourage caffeine rich products e.g., coffee
- Offer smoking cessation programmes
What is the ideal normal blood pressure?
90/60 - 120/80mmHg
What is Stage 1 hypertension?
Clinic BP: 140/90mmHg β 160/100mmHg AND ABPM: β₯135/85 mmHg Offer anti-hypertensive drug treatment to people <80years who have 1 or more of the following: β’ Target organ damage (left ventricular hypertrophy, CKD, retinopathy). β’ Established CVD β’ Renal disease β’ Diabetes β’ 10-year CVD risk of 20% or more
What is Stage 2 hypertension?
Clinic BP: 160/100mmHg β 180/120mmHg
AND
ABPM: β₯150/95 mmHg
Treat everyone with stage 2 hypertension
What is severe hypertension?
Clinic systolic BP: β₯180mmHg
OR
Clinic diastolic BP: β₯120mmHg
What is the step 1, step 2 , step 3 and step 4 treatment for an adult with T2DM with diabetes or for adults ages <55years that are not of black African or African-Caribbean family origin who have hypertension?
Step 1 = ACEi/ARB
Step 2= ACEi/ARB + CCB/thiazide like diuretic
Step 3= ACEi/ARB + CCB + Thiazide like diuretic
Step 4= Resistant hypertension
β’ For those with K+ levels of 4.5mmol/l or less = Consider adding low dose spironolactone
β’ For those with K+ levels of > 4.5mmol/l = Alpha or beta blocker
What is the step 1, step 2 , step 3 and step 4 treatment for adults aged 55years or over with no T2DM or for those of black African or African-Caribbean family origin?
Step 1= CCB
Step 2= ACEi/ARB + CCB/thiazide like diuretic
Step 3= ACEi/ARB + CCB + Thiazide like diuretic
Step 4= Resistant hypertension
β’ For those with K+ levels of 4.5mmol/l or less = Consider adding low dose spironolactone
β’ For those with K+ levels of > 4.5mmol/l = Alpha or beta blocker
When using a further diuretic (spironolactone) in resistant hypertension what monitoring must be done?
- Blood Na+
- Blood K+
- Renal function
Which CCB should be avoided for patinets with HF?
All CCB should be avoided in patients with HF except amlodipine
- If a thiazide like diuretic is being started which one is preferred in hypertension?
Indapamide (however if certain patients are already having treatment with conventional diuretics such as Bendroflumethiazide or hydrochlorothiazide and are stable with well controlled BP continue with that treatment.
Before moving to each next step in the treatment of hypertension; patients medications must be reviewed to ensure they are being taken at the optimal doses and adherence must be discussed.
Before considering further treatment for a person with resistant hypertension:
β’ Confirm elevated clinic BP levels using ABPM
β’ Assess for postural hypotension
β’ Discuss adherence
What are the clinic and ABPM blood pressure targets for patients over and under 80years.?
Target clinic BP for patients under 80years: below 140/90mmHg
Target clinic BP for patients over 80years: below 150/90mmHg
Target ABPM for patients under 80years: below 135/85mmHg
Target ABPM for patients over 80years: below 145/85mmgHg
What is the clinic BP target in renal disease?
Below 140/90mmHg
Below 130/80mmHg ο if CKD, diabetes, if urine albumin to creatinine ratio exceeds 70mg/mmol.
What is the target BP in pregnancy?
<150/100 -chronic hypertension
<140/90 β chronic hypertension and if target organ damage or given birth
What is the target BP in T1DM patients?
<135/85mmHg
<130/80mmHg β if complications e.g., eye, kidney, or cerebrovascular disease
