1 atherosclerosis
1. Atherosclerosis
  • Inner lining of arteries become lined with plaque
  • Plaque – buildup of fatty substances
  • Think of water pipes freezing…Water is not able to get to where it needs to go!
how does this occur
How does this occur?
  • Poor Diet
  • Sedentary Lifestyle!
2 coronary artery disease heart disease
2. Coronary Artery Disease (Heart Disease)
  • Greatest killer of all CV diseases! Leads to heart attack!
  • How a heart attack happens:
    • 1. In order to function, the heart has to have oxygen, thus it needs blood!
    • 2. Blood (and O2) are delivered to the heart via coronary arteries
    • 3. When these arteries become clogged, O2 cannot reach the heart and a heart attack may occur!
coronary heart disease
Coronary Heart Disease…
  • Think of it like this…
  • Coronary arteries are like the power cords to the heart. When the power is interrupted, the heart does not function properly
signs of a heart attack
Signs of a Heart Attack
  • Chest discomfort
  • Discomfort in other areas of the upper body
  • Shortness of breath
  • Other signs may include breaking out in a cold sweat, nausea or lightheadedness.

3 congestive heart failure
3. Congestive Heart Failure
  • Your heart is a big muscle (cardiac muscle)
  • CHF occurs when your muscle becomes overworked, and lacks strength
congestive heart failure
Congestive Heart Failure
  • Heart is not strong enough to pump blood to the rest of the body.
  • Blood pools and causes body/heart tissues to swell! This causes the congestion!
slide14
Think of it like this…
  • A sump pump! If that pump doesn’t get the water out from your basement, it will pool, creating a mess!
4 stroke
4. Stroke
  • Your brain needs O2 also!!!
  • Stroke occurs when blood flow is interrupted to the brain (clot in blood vessel)
  • When O2 does not reach the brain, brain cells die
strokes
Strokes
  • Mild strokes may cause dizziness, weakness, or numbness.
  • However serious strokes causes speech impairments, memory problems, and loss of motor control.

6.

Anemia: decrease in number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood.

7. Hemophilia- blood does not clot

so how do we avoid all these diseases
So… How do we avoid all these diseases!?

Heart disease can be hereditary
  • If your parents/grandparents had heart disease, you may be more likely to get it.
how can exercise help the heart
How can exercise help the heart?
  • Exercise makes the heart more efficient!
  • Exercise increases stroke volume – the amount of blood your heart pumps per contraction
  • Exercises decreases resting heart rate – amount of times your heart beats per minute while resting.
  • Exercise makes your heart’s life easier!!!
