Transcript

  • 1. Hypertension The Silent Killer Sarasota Memorial Hospital Cardiac Rehab 2010
  • 2. Silence is NOT Golden • Most people who have hypertension have NO symptoms. • Approximately 1 in 3 Americans have high blood pressure; • Only 77.6% are aware of their condition • 67.9% currently under treatment • 44.1% have it under control • 55.9% do not
  • 3. What is Hypertension Hypertension occurs when the pressure in the arteries becomes high, causing the heart to work harder than normal to pump the blood throughout the body.
  • 4. Blood Pressure Defined The pressure in the arteries when the heart beats and when it is at rest. Systolic: pressure during a heart beat (the top number) Diastolic: pressure when heart is at rest (the bottom number)
  • 5. American Heart Association’s Recommended Values Category Systolic Diastolic Normal < 120 < 80 Prehypertension 120-139 80-89 Hypertension 140-159 90-99 stage I Hypertension + 160 + 100 stage II
  • 6. The Heart As A Pump  Certain nerve impulses cause arteries to constrict and dilate.  The heart pumps blood through the vessels.  If the vessels are wide open, blood flows freely. If vessels are narrowed, more pressure is required for blood to flow through.
  • 7. Complications from Uncontrolled Hypertension  Damage to arteries  Aneurysm  Heart failure  Trouble with memory or understanding
  • 8. Complications from Uncontrolled Hypertension  Blocked or ruptured blood vessels to the brain  Weakened blood vessels in the kidneys  Thickened, narrowed, or torn blood vessels in the eyes
  • 9. Non-Modifiable Causes  Age  Race  Genetics
  • 10. Modifiable Causes  Smoking  Too much salt  Alcohol  Too little  Inactivity potassium  Obesity  Other conditions High cholesterol Stress    Diabetes  Kidney disease  Sleep apnea
  • 11. How to Control Blood Pressure STOP SMOKING The nicotine present in tobacco products causes:  Decreased oxygen to the heart.  Increased blood pressure and heart rate.  Increase in blood clotting.  Damage to cells that line coronary arteries and other blood vessels.
  • 12. Get Moving!!!  Make physical exercise a regular part of your life  Strengthens the blood vessels and helps to control BP.  30-60 min a day to control blood pressure
  • 13. Drop the Extra Pounds  Even a 10 lb weight loss can lower blood pressure  Excess weight strains the heart and increases blood pressure  Make healthy eating a way of life
  • 14. Eat For Your Life  Avoid fad diets, diet pills, yo-yo dieting.  Eat plenty of whole grains,  8 servings of fruits, vegetables/day  Legumes
  • 15. Limit Salt/Sodium Intake  No more than 1500mg per day  Limit process foods; add more fresh fruits, vegetables, and whole grains  Follow the DASH diet  www.dashdiet.org
  • 16. Limit Alcohol Intake Check with your doctor if it is okay to drink alcohol and how much. Generally one cocktail, beer or wine per day is acceptable.
  • 17. When All Else Fails Sometimes even doing all the right things will not lower your blood pressure to an acceptable level. When that happens, your doctor may put you on one or more blood pressure medications.
  • 18. Know Your Medications  Always ask your doctor what medicine he/she is giving you and what it is for.  Pay attention to how the new medication makes you feel.  Report any adverse side effects to your doctor.  Never stop taking blood pressure medication without the permission of your doctor.
  • 19. Stay On Top Of It  If you know you have a problem with blood pressure, it may be a good idea to monitor it at home and record your readings for your doctor.
