The seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure
JNC7 Report: (2003)
Blood pressure Goal according to JNC7 Report
BP less than 140/90 Tx; Life style Modification
Stage 1 HTN according to JNC7 Report
Sys. 140-159 or Dia: 90-99 TX: Pharmacologic/ Lifestyle
Stage 2 HTN according to JNC7 Report
Sys: equal or> 160 Dia: Equal to >100
Hypertension Diagnosis
Average of 2 or more seated BP measurements from 2 or more clinical encounters
Optimal BP goals vary depending on:
- Age
- Concomitant Diseases
- Demographics
- Drug Interactions
- Economic Considerations
- Guidelines
Patient w/o CKD but w/ DM (non-black)
Initiate;
Thiazide, ACEI, ARB or CCB or Combo
Patient w/o CKD but w/ DM (black)
Initiate:
Thiazide or CCB Alone or Combo
Patient with CKD and with or without DM
Initiate:
ACEI: or ARB Alone or combo w/ other classes
Drug Treatment Titration Strategies
A. Maximize 1st Rx before adding 2nd
B. Add 2nd Rx before reaching Max dose of 1st Rx
C. Start w/ 2 Rxs separately or as fixed-dose combo
Which combination of the Guideline medications should not be combined
ACEI and ARBs
What is the drug of choice when; treating hypertension with comorbid diabetes and/or CKD?
ACEI or ARB (Angiotensin Receptor blocker)
Guideline medications contraindicated in pregnancy are
ACEI and ARBs
Largely Determines Systolic Blood Pressure
Cardiac Output (HR * Stroke Volume)
Cardiac Output is a function of
- Stroke Volume
- Heart Rate
- Venous Capacitence
Largely Determines Diastolic Blood Pressure
Total Peripheral Resstance
Total Peripheral resistance is the function of
Vascular resistance and Heart
Blood Pressure fluctuations throughout the day
Lowest= Sleep
Rises =Awakening
Peaks =Midmorning
Blood pressure is a product of
Cardiac output X Total Peripheral Resistance
