  • Chapter 10: Reducing Your Risk of Cardiovascular Disease Heart Disease continues to be the number 1 killer in the United States, even though mortality rates have declined in recent years due to better medical treatment for Cardiovascular Disease. The term cardiovascular refers to the heart (cardio) and the vessels that carry blood (vascular). Cardiovascular disease starts as early as two years of age and progresses into a life threatening disease, even into early adulthood. These factors will be discussed in this presentation as well as reducing our chances from suffering from this preventive condition.
  • Transcript

    • 1. Chapter Ten Reducing Your Risk of Cardiovascular Disease
    • 2.  
    • 3. The Heart
      • 4 chambers (atrias/ventricles)
      • Size of a fist
      • Weighs about 1 pound
      • Function: pump to create pressure for blood movement
      • Location: between the lungs ( thorax ), 2/3 towards the left midline
    • 4. Vascular System
      • Blood vessels
        • Arteries (carry blood away from heart)
        • Veins (returns blood to the heart)
    • 5. Heart Beat Stimulation
      • Signal sends impulses from brain to the heart
      • SA node (pacemaker of the heart) creates an electrical impulse
      • An electrical impulse spreads from the right side to the left (ECG)
      • Electrocardiograph measures the cardiac electrical functioning
    • 6. Blood
      • Average person has 5 quarts of blood
      • Functions:
        • Transport nutrients
        • Clotting to prevent blood loss
        • Protection against toxins and microorganisms
        • Regulate body temperature
        • Maintain ph
        • Regulate water content
    • 7. Cardiovascular Risk Factors
      • Risk factors that cannot be changed:
        • Age
        • Male Gender
        • Heredity
    • 8. Cardiovascular Risk Factors (cont’d)
      • Risk factors that can be changed:
        • Tobacco Smoking
        • Physical Activity
        • High Blood Cholesterol level
        • High Blood pressure
        • Diabetes Mellitus
        • Obesity and overweight
    • 9. Forms of Cardiovascular Disease
      • Coronary artery disease
        • atherosclerosis
      • Hypertension
      • Stroke
      • Congenital heart disease
      • Congestive heart failure
      • Rheumatic heart disease
      • Peripheral artery disease
    • 10. Prevention and Treatment of Hypertension
      • Weight reduction
      • Physical activity
      • Moderation in alcohol use
      • Sodium restriction
      • Stress reduction
    • 11. Chapter Ten Reducing Your Risk of Cardiovascular Disease
