Hypertension Flashcards
What does the first Korotkoff sound indicate?
Systolic Blood Pressure
What is indicated by the end of Korotkoff sounds?
Diastolic Blood Pressure
Hypertension is more common in men until which age group?
HTN is more common in women after 55-64
The percentage of the population with HTN corresponds directly to which condition?
CVD
What are some (8) risk factors for Atherosclerosis?
- High LDL
- Low HDL
- Sex Hormones
- HTN
- Renal Failure
- Diabetes
- Smoking
- Sedentary Life Style
What is the leading cause of death in the US?
CVD (+ Stroke)
People with HTN are more likely to develop which 3 conditions (and risk)?
- Coronary Artery Disease (x3)
- Congestive Heart Failure (x6)
- Stroke (x7)
What is the tightest disease link with elevated BP?
Stroke
What is considered “normal” BP by JNC 7 and what are the recommendations for lifestyle modifications and drugs?
120/80
- Encourage LSM
- No Drugs
What is considered “Pre-HTN” by JNC 7 and what are the recommendations for lifestyle modifications and drugs?
120-139/80-89
- Yes LSM
- No Drugs
What is considered “Stage 1 HTN” by JNC 7 and what are the recommendations for lifestyle modifications and drugs?
140-159/90-99
- Yes LSM
- Mono or Combo Therapy
What is considered “Stage 2 HTN” by JNC 7 and what are the recommendations for lifestyle modifications and drugs?
160+/100+
- Yes LSM
- Combo Drug Therapy
What is Kaplan’s definition of HTN?
“HTN is that level of blood pressure at which the benefits of therapy outweigh the risks”
Lowing BP decreases the risk of which three conditions?
- Stroke**
- MI
- CHF
* *Lowering BP prevents Strokes better than it prevents MI
What are compelling indications for HTN?
- Heart Failure
- Diabetes with Proteinuria
- CAD (prior MI increases risk)
- Chronic Renal Insufficiency
- CVA
What formula allows estimation of BP?
MAP - CVP = CO x TPR
**You can ignore CVP since it is so low
How would an increase in BP effect CO and TPR?
Either CO or TPR (or both) would increase
