Hypertension 1&2 Flashcards
What is essential hypertension?
rise in blood pressure of unknown cause that increases risk for cerebral, cardiac and renal events
What should be done if clinic BP is 140/90mmHg or more?
offer ABPM to confirm diagnosis
when using the following to confirm diagnosis ensure at least two measurements per hour during the persons usual waking hours (usually 14/day)
What are the guidelines for HBPM?
- Two consecutive seated measurements, 1 minute apart
- BP is recorded twice a day for at least 4 days and preferably for 7 days
- measurements on the first day are discarded- average value of all remaining is used
Define stage 1 hypertension
Clinic BP is 140/90 mmHg or higher and
ABPM or HBPM daytime average is 135/85 mmHg or higher
Define stage 2 hypertension
Clinic BP 160/100 mmHg or higher and
ABPM or HBPM daytime average is 150/95 mmHg
or higher.
Define severe hypertension
Clinic BP is 180 mmHg or higher or
Clinic diastolic BP is 110 mmHg or higher.
What tests should be arranged for all hypertensives?
> test urine for protein
take blood to measure glucose, electrolytes, creatinine, estimated glomerular filtration rate and glucose
examine fungi for hypertensive retinopathy
arrange a 12 lead ECG

Diabetes
What are the guidelines for clinic BP in patients with treated hypertension?
