  1. How is HTN diagnosed?
    SBP > 140 and DBP >90 based on the average of two or more seated BP readings on two or more office visits.
  2. Describ:
    Pre-HTN

    Stage 1 HTN

    Stage 2 HTN
    Pre-HTN = SBP 120-139 / DBP 80-89

    Stage 1 HTN = SBP 140-159 / DBP 90-99

    Stage 2 HTN = SBP >=160 / DBP >= 100
  3. When would a diagnosis of secondary HTN be considered?

    Doubles the risk of cardiovascular disease in 40-70 year olds.
  6. When is secondary HTN considered?
    Young onset of HTN <30 or older onset >50.
  7. What are causes of reversable HTN?
    • Obesity, obstructive sleep apnea, renovascular disease, chronic steroid therapy, Cushing's syndrome, primary hyperaldosteronism, pheochromocytoma, coartation of the aorta, thyroid disease, parathyroid disease, and excess ETOH intake.
    • Drugs: NSAIDS, Cox-2 Inhibitors, Diet pills, oral contraceptives, erythropoietin, cocaine, amphetamines, steroids, tacrolimus, cyclosporine, ephedra, licorice, smoking, chewing tobacco.  
  8. When is malignant HTN diagnosed?
    SBP>=180 / DBP >= 110 and evidence of acut target organ damage. 
  9. What is considered evidence of target organ damage in HTN?
    • Papilledema, hemorrhages, or exudates on funduscopic exam.
    • Change in mental status or neurological deficts on exam.
    • EKG consistent with myocardial ischemia or infarction.
    • Chest xray showing heart failure or aortic disection.  
    • Renal dysfunction evidenced by hematuria, proteinuria, and elevated serum creatinin. 
  10. A displaced PMI and S4 heart sound may indicate?

  13. What is pseudo-HTN?
    When too much calcification in the vessel wall does not allow the cuff to proper compress the vessel wall. 
  14. What is one of the earliest EKG indications of HTN?
    Left atrial enlargement.  Echo is most usefull in detecting increasing Left ventricular thickness.
  15. What is Isolated Systolic Hypertension? (ISH)
    SBP >160 with normal DBP 86 or less as a consequence of atherosclerocitic thickening of the vessels.  Effects nearly half of all adults >65 y/o.
