Non infectious diseases

Non-Infectious Diseases


Non infectious disease

Non-Infectious Disease

  • Not caused by pathogens

  • Cannot be transmitted to other people

  • Risk factors:

    • Genetics

    • Life-style

    • Environmental factors


Genetic risk factors

Genetic Risk Factors

  • Determined by genes

  • Congenital disease is present at birth

    • Others don’t show up until later in life

  • Familial Disease Tendency

    • Disease runs in family


Genetic risk factors1

Genetic Risk Factors

  • Recessive gene disorders

    • Need recessive gene from both parents

    • Can be a carrier

    • Cystic fibrosis & sickle cell anemia

  • Down syndrome

    • Born with extra chromosome


Genetic risk factors2

Genetic Risk Factors

  • Sex-linked disorders

    • Linked to x chromosome (female)

    • Can be recessive in females

    • Color blindness, hemophilia, & muscular dystrophy


Environmental risk factors

Environmental Risk Factors

  • Pollution

  • Smoke

  • Sunlight

  • Radiation

  • Altitude

  • Water


Lifestyle risk factors

Lifestyle Risk Factors

  • Diet

  • Obesity

  • Exercise

  • Alcohol

  • Tobacco

  • Stress

  • Sleep


Leading cause of death in us

Leading Cause of Death in US

  • Heart disease: 631,636

  • Cancer: 559,888

  • Stroke : 137,119

    • (CDC, 2006)


Cardiovascular disease

Cardiovascular Disease

  • Disease of Cardiovascular system

  • CV system is…

    • Heart

    • Blood Vessels

      • Arteries

      • Vein

      • Capillaries

    • Blood


Types of cv disease

Types of CV Disease

  • Hypertension

  • Arteriosclerosis

  • Atherosclerosis

  • Heart Attack

  • Stroke

  • Arrhythmias

  • Heart Valve Disorder

  • Varicose Veins


Hypertension

Hypertension

  • High Blood Pressure

  • Normal=120/80

  • Over 120/80= At risk

  • High=150/90

  • Thickening of blood vessel walls

  • Narrows passageways for blood


Arteriosclerosis

Arteriosclerosis

  • Hardening of the arteries

  • Narrows blood vessels & blocks blood flow

  • Atherosclerosis

    • Fat deposits in blood vessels


Heart attack

Heart Attack

  • Caused by lack of oxygen delivery to cells

  • Coronary heart disease

    • Blockage of coronary arteries

    • Caused by fat deposits and/or blood clots

    • Causes heart attack

  • Cardiac Arrest

    • Entire heart stops


Stroke

Stroke

  • Disrupts blood flow to brain

  • No oxygen to brain

  • Brain cells die

  • Caused by fatty deposits, blood clots, or burst arteries

  • Aneurysm

    • Weak spot in blood vessel that can burst


Stroke1

Stroke

  • Effects

    • Speech

    • Senses

    • Movement

    • Memory

    • Behavior

    • Depending on side of the brain


Heart valve disease

Heart Valve Disease

  • 4 valves in heart

  • 2 between atria & ventricle

  • 2 between heart & arteries

  • Bypass Surgery


Arrhythmias varicose veins

Arrhythmias & Varicose Veins

Arrhythmias

  • Abnormal heart beat

  • Pacemaker

  • Defibrillator

  • Varicose Veins

  • Large blue veins

  • One-way valves don’t work


Testing diagnosis

Testing & Diagnosis

  • Electrocardiogram (ECG/ EKG)

    • Graphs electrical impulses and heart beats

  • Stress Test

    • ECG during exercise

  • Chest X-Ray

    • Picture of heart


Prevention

Prevention

  • Don’t smoke

  • Exercise regularly

  • Manage stress

  • Manage diet

    • Avoid saturated fat & cholesterol

    • Replace red meat with chicken and fish

    • Eat more fruits & veggies

    • Avoid sweets, oils, & fats

Discussion

Discussion

  • Define HDL, LDL, Cholesterol. How are they different? How are they similar?

  • Describe angiogenesis. What does it do? Why does this help increase heart health?

  • Describe the symptoms of heart disease.


What is cancer

What is Cancer?

  • Define the 5 different types of cancer?

  • What is the difference between benign & malignant tumors?

  • What is metastasis? How does it occur?

  • What causes cancer?
