More Info
									Essential hypertension (also called
primary or idiopathic hypertension) is
the form of hypertension that by
definition, has no identifiable cause.
 PreHypertension - Systolic blood pressure (SBP) 120-
  139 mm Hg or diastolic blood pressure (DBP) 80-89
  mm Hg
 Stage I hypertension - SBP 140-159 mm Hg or DBP
  90-99 mm Hg
 Stage II hypertension - SBP >160 mm Hg or DBP >
  100 mm Hg

              Classification of Hypertension
                  Risk factors
 Being overweight or obese.
 Smoking
 Drinking a lot of alcohol
 Having a sedentary lifestyle
 Eating too much salt (sodium)
 Having other health conditions
 Taking certain medicines
 Stress
 Having higher than normal blood pressure
Other factors also increase your
 risk, but they are beyond your

         Symptoms of hypertension
 One of the symptoms of hypertension is chronic
   Dizziness or Vertigo
   Blurry or double vision
   Drowsiness
   Nausea
   Shortness of breath
   Heart palpitations
   Fatigue - general tiredness
    Symptoms of hypertension
A flushed face
A strong need to urinate often
 (especially during the night)
Tinnitus (a ringing or buzzing in
 the ears)
Heart Complications
                Coronary Artery Disease
                Heart Failure
                Cardiac Arrythmias
 Stroke
 Dementia
 Eye Damage
 Sexual Dysfunction
      Treatments and drugs
 Changing your lifestyle
 Thiazide diuretics
 Beta blockers
 Angiotensin-converting enzyme (ACE)
 Angiotensin II receptor blockers
 Calcium channel blockers
 Renin inhibitors
If you're having trouble reaching your
blood pressure goal with combinations
of the above medications, your doctor
may prescribe:
 Alpha blockers
 Alpha-beta blockers
 Central-acting agents
 Vasodilators
      Resistant hypertension
 If blood pressure remains stubbornly high despite
 taking at least three different types of high blood
 pressure drugs, one of which should be a diuretic, you
 may have resistant hypertension. Resistant
 hypertension is blood pressure that's resistant to
 treatment. People who have controlled high blood
 pressure but are taking four different types of
 medications at the same time to achieve that control
 also are considered to have resistant hypertension.
         Hypertensive Crises
 Hypertensive crises encompass a spectrum of clinical
 situations that have in common severely elevated
 blood pressure (BP), usually higher than 180/110 mm
 Hg, together with progressive or impending target
 organ damage.
