Hypertension Flashcards
What are the blood pressure values for pre hypertension?
greater than 120/80
Define stage 1 hypertension?
Blood pressure greater than 140/90
Define stage 2 hypertension?
blood pressure greater than 160/100
What is primary/ essential hypertension?
Hypertension with no known cause
What % of hypertension is primary hypertension?
90%
2 examples of primary hypertension
Pheochromocytoma
Rental artery stenosis
How many worldwide deaths per year are due to hypertension?
9.4 million
What percentage of adults don’t know they are hypertensive?
40-45%
Risk factors for essential hypertrophy
family Age sex ethnicity chronic kidney disease
what does ANP stand for?
atrial natriuretic peptide
What is released from the JGA when low blood pressure is sensed?
Renin
Bp= ?X?
Bp= Q X TPR
At what mean arterial pressure does max baroreceptor sensitivity occur?
80-100mmHg
What are the CV related risk factors caused by hypertension?
Atherosclerosis Anyeurysm Microdamage diastolic dysfunction arterial stiffness- LV hypertrophy
How much can physical activity interventions lower systolic blood pressure by? And how much of a decrease in CVD risk does tis equate to?
decrease by 5-7 mmHg
equating to a 20-30% decrease risk of CVD
Contraindiction for BP=
200/110 mmHG
What type of exercise causes the biggest decrease in systolic bp?
running
What causes a decrease in blood pressure after acute exercise?
resetting of baroreceptors
decrease in total peripheral resistance
Four considerations when working with hypertensive patients
Stage 2 patients need drug therapy first
terminate exercise at 250/115 mmHG
Antihypertensives can impair thermoregulation
Account for potential impaired vision
