Definition
Goal BP is 130/80

HTN in Children and Adolescents |
|
Definition
- Almost always, HTN is secondary to something else
- Lifestyle modifications may be more useful in children

Term
|
Definition
Goal BP is 140/90

First Part
Drugs:
Compared chlorthalidone, amlodipine, and lisinopril

Thiazide diuretics are superior to ACEI or CCB in preventing coronary outcomes related to HTN and should be considered first line therapy for HTN
Second Part
Drugs:
doxazosin vs. chlorthalidone
Outcome:
- Trial was stopped
- Those receiving doxazosin had 25% more cardiovascular events and were twice as likely to be hospitalized for CHF compared to chlorthalidone
