hypertension Flashcards
hypertension isnt a disease what is it?
it is a risk factor for other disease states such as MI, HF, stroke, CKD ,PVD
if a patient had HPT but no est CVD how are they treated?
they are treated as primary
prevention rather than secondary prevention.
what are the most powerful risk predictors of absolute cardiovascular risk?
logical changes, such as left ventricular hypertrophy and renal impairment but many factors including increasing blood pressure and lipids, smoking, and male sex interact to determine absolute risk.
give some examples of possible secondary hypertension cause
renal artery stenosis
coartation of aorta
cushing’s syndrome
drug induced
what are the important points to remember when taking a blood pressure?
- Check for pulse irregularity and if present measure
manually - Standardisethe environment
- Use appropriate cuff size for patient’s arm
what should you do when taking a blood pressure in a person with symptoms of postural hypotension?
–measure blood pressure with the person either
supine or seated
–measure blood pressure again with the person
standing for at least 1minute before
measurement
what should you do if blood pressure measured in the clinic is 140/90 mmHg or higher?
– Take a second measurement during the consultation.
– If the second measurement is substantially different from the
first, take a third measurement.
Record the lower of the last 2 measurements as the clinic
blood pressure.
if clinical blood pressure is between 140/90 and 180/120 what should you do to confirm diagnosis?
offer ambulatory blood pressure monitoring
(ABPM) to confirm the diagnosis of hypertension
what if a ABPM is unsuitable/ unable to tolerate?
offer home blood pressure monitoring (HBPM) to confirm the diagnosis of hypertension
when would you confirm a diagnosis of HPT ?
in people with a:
– clinic blood pressure of 140/90 mmHg or higher and
– ABPM daytime average or HBPM average of 135/85 mmHg
or higher.
how often should you measure a persons BP with diabetes?
at least annually- type 2
offer lifestyle
what is the target BP for someone aged 70/80?
80+ 150/90
less than 80 but with underlying condition= 135/85
what do you offer to all people with hypertension to assess CVD risk and target organ damage?
- Test for the presence of protein in the urine by sending a urine
sample for estimation of the albumin: creatinine ratio and test for
haematuriausing a reagent strip - Take a blood sample to measure glycated haemoglobin(HbA1C),
electrolytes, creatinine, estimated glomerular filtration rate, total
cholesterol and HDL cholesterol - examine the fundi for the presence of hypertensive retinopathy
- arrange for a 12-lead electrocardiograph to be performed
what would you do if a person has severe hypertension 180/120 but no symptoms or signs indicating same- day referal?
carry out investigations for target
organ damage as soon as possible:
– If target organ damage is identified, consider starting antihypertensive drug treatment immediately, without waiting for the results of ABPM or HBPM.
– If no target organ damage is identified, repeat clinic blood pressure measurement within 7days.
when do you refer 180/120?
– signs of retinal haemorrhageor papilloedemaor
– life-threatening symptoms such as new onset confusion,
chest pain, signs of heart failure, or acute kidney injury
