Cardiovascular Disease
  • Medical disorders that affect the heart and blood
    vessels.
  • Heart, blood, and arteries are parts of the
    circulatory system.
  • When a problem affects one part, the entire
    system is threatened.
  • Your lifestyle choices and health habits you
    adopt now can directly influence your future
    risk.
  • CVD accounts for 45 of all deaths among people
    aged 45 years or over.

Risk Factors
  • The result of blood vessels inability to carry
    oxygen and nutrients to the heart which allow it
    to pump blood effectively
  • Risk factors
  • Hypertension (lt140/90 healthy 120/80)
  • Systolic pressure on arteries when the heart
    beats.
  • Diastolic pressure on arteries when the heart is
    not beating
  • Cholesterol (240 healthy lt200)
  • Smoking
  • Age
  • Gender
  • Race
  • Family History
  • Obesity
  • Lifestyle
  • (Activity level, secondhand smoke, stress, diet)

8
Hypertension
  • Blood pressure is the force of blood against the
    walls of blood vessels as blood flows through the
    circulatory system.
  • Known as the silent killer
  • Risk Factors obesity, alcohol use, inactivity,
    smoking, excessive salt intake.
  • Prevention no cure controlled by life style
    changes- diet, losing excess weight and exercise.
    Medication.

Cholesterol
10
Artery Disease
  • Atherosclerosis
  • Arteriosclerosis
  • Plaque obstructs blood flow
  • A slow, progressive condition of the blood
    vessels
  • Arteries become narrowed due to build-up of fat
    and cholesterol, causing inflammation .
  • The deposits harden, causing plaque
  • Plaque can break off and clog an artery leading
    to heart attack or stroke
  • Treatment includes lowering fat intake and
    cholesterol levels, losing weight
  • Hardening of the arteries
  • A condition in which the walls of the arteries
    become thick and loses their elasticity.
  • Most common cause of death in the U.S.

11
Angina
  • Chest Pain
  • Pain and tightness in the chest caused by the
    lack of oxygen to the heart.
  • Serves as an SOS- warns body the heart is in
    distress.
  • Pain can last a few minutes
  • Treatment
  • change health behaviors
  • medications to dilate the blood vessels
  • sometimes surgery.

12
Heart Attack
  • Part of the heart starves and dies due to the
    supply artery becoming completely blocked
  • End result of a long term disease process
  • Can be fatal- immediate response can be the
    difference
  • Distress may extend into one or both arms, upper
    abdomen.
  • Risk Factors
  • High cholesterol, stress, overeating, smoking,
    and hypertension.
  • Treatment
  • Angioplasty or bypass surgery
  • Exercise, eat well, medication

13
Congestive Heart Failure
  • A progressive weakening of the heart muscle that
    reduces its ability to pump effectively
  • Atherosclerosis- biggest cause
  • When the heart cannot pump well, results in
    either poor output- (blood cannot get to the
    vital organs- or the blood backs up leading to
    excess fluid)
  • Medications can be prescribed to prevent
    episodes, but it is important to watch fluid and
    salt intake, monitor weight and seek help early.

14
Stroke
  • Similar to a heart attack occurring in the brain
  • An interruption of the flow of blood to any part
    of the brain.
  • Warning signs
  • Weakness/numbness of face, arm, leg on one side
    of body
  • Loss of speech or trouble understanding people
  • Loss of vision or dimness in one eye
  • Dizziness or sudden falls
  • Causes
  • Blocking of the cerebral artery by a blood clot-
    Thrombus
  • Diseased artery in the brain can burst and flood
    the brain tissue with blood- Cerebral Hemorrhage
  • About 2/3 of stroke victims are over 65
  • Main risk factor is high blood pressure.

15
Surgical Procedures
  • Heart Transplant- replacing damaged heart with a
    heart from a person who recently died.
  • Coronary Bypass Surgery- creates detours around
    obstructed arteries so blood can reach the heart.
  • Balloon Angioplasty- catheter is inflated in site
    of blockage to push plaque against artery wall to
    open a path.
  • Heart Valve Surgery- valve can be too tight or
    big, surgery replaces defective valve with an
    artificial one made of metal or plastic.

BE KNOWLEDGABLE ON EMERGENCY CARE
CPR Cardio-pulmonary resuscitation
chest compressions to circulate oxygenated blood
CALL 911

Reduce your risk?
  • Reduce/stop tobacco, alcohol and drug exposure
  • Decrease diabetes symptoms
  • Dietary modifications
  • Increased physical activity
  • Reduce blood pressure
  • Dietary modifications (more fruit/veg, reduced
    sodium/fat)
  • Increased physical activity
  • Improve cholesterol (lower total LDL, raise
    HDL)
  • Dietary modifications (less simple carbs
    saturated/trans fats)
  • Increased physical activity
  • Stress Management/reduction
  • Physical Activity
  • Maintain a weight that is healthy for you
  • Doctor Visits
