What percent of patients with diagnosed HTN are controlled?
25%
Relationship between age and HTN
HTN increases w/age
At what age does pulse pressure change and how
PP increases d/t decreased diastolic pressure
after age 50
Hypertension incidence: blacks vs whites
more common in blacks
Difference between primary and secondary hypertension
Most common cause of HTN before age 50
primary HTN
Primary HTN accounts for ___ percent of all HTN
95%
Age range for typical onset of primary HTN
25-55yo
Some multifactorial causes of HTN: contribution by arterioles
Some multifactorial causes of primary HTN: contribution by baroreceptors
decreased Baroreceptor sensitivity
Some multifactorial causes of primary HTN: contribution by endothelium
Endothelial dysfunction
Some multifactorial causes of HTN: contribution by sympathetic nervous system activity
Increased Sympathetic nervous system activity
Some multifactorial causes of primary HTN: contribution by α and β-adrenergic receptors
Decreased α and β-adrenergic receptor response
Some multifactorial causes of HTN: contribution by plasma renin
Low plasma renin activity
Some multifactorial causes of primary HTN: contribution by insulin system
Insulin resistance
Some multifactorial causes of primary HTN: contribution by neurohormonal factors
Neurohormonal factors that decrease vascular response (poor dilation)
