  1. Page 675 Cardiovascular Diseasesdiseases that affect the heart or blood vessels

  2. Hypertension • high blood pressure • Called the “Silent Killer” – no symptoms in early stages • pressure of 140/90 is considered high • stress, smoking, poor diet as well as heredity contribute to high blood pressure

  3. Effects of high blood pressure

  4. CORONARY ARTERIES • Arteries that feed the heart muscle itself.

  5. ATHEROSCLEROSIS • the process in which plaques accumulate on artery walls. • arteries become thicker and lose their elasticity • caused mainly by food choices – especially a high in take of saturated fats and cholesterol

  6. Atherosclerosis

  7. Plaque surgery

  8. Anti smoking commercial

  9. ANGINA PECTORIS • chest pain that results when the heart does not get enough oxygen • warning signal – get to medical help

  10. ARRHYTHMIAS • irregular heartbeats • heart may seem to skip a beat or beat very quickly or very slowly

  11. HEART ATTACK • damage to the heart muscle caused by a reduced or blocked blood supply • Heart muscle not getting enough oxygen • Part of heart dies, the rest keeps beating B

  12. Symptoms of a Heart Attack • mild pain or discomfort in chest • pressure or pain in chest • pain in arm, neck or jaw • nausea or vomiting • sweating • shortness of breath • pain in back ( especially in women) • Immediate response to symptoms is the difference between life and death

  13. How does a heart attack happen

  14. Congestive Heart Failure • Heart gradually weakens • Cannot maintain regular pumping rate • No Cure

  15. CARDIAC ARREST • Heart stops beating in a rhythmic way (ventricular fibrillation)

  16. TREATMENTS (p.61) • Electrocardiogram (EKG)- measures electrical activity of the heart

  17. ECG

  18. TREATMENTS • Angioplasty- balloon tipped tube is inserted into blocked artery and inflated

  19. Angioplasty and stenting

  20. TREATMENTS • By-pass surgery- A blood vessel is used to go around the clot A

  21. STROKE • blood flow to the brain is interrupted • Symptoms: • severe headache • confusion • loss of speech and/or vision • unexplained dizziness • weakness/numbness in face, arm and/or leg on one side • symptoms may be temporary or permanent B

  22. STROKE

  23. Teens and Cardiovascular Disease • Page 692!! • (Read in aloud in class)

  24. Risk Factors for CV disease • Non-controllable (p.693) • Heredity • Gender – men at greater risk however, women are less likely to survive • Age – risk increases with age

  25. Risk Factors for CV disease • Controllable (page 693) • Tobacco Use • High Blood Pressure • High Cholesterol • Physical Inactivity • Excess Weight • Stress • Alcohol and Drug Use
