Risk factors
Both ___________ and _______ are both forms of cardiovascular disease.
Atherosclerosis and stroke
____________ is the root form of most heart disease and can lead to
strokes, heart attacks, and hypertension.
The most common form of cardiovascular disease; characterized by plaques along the inner walls of the arteries.
Too much fat, especially ______ ___, can increase LDL and trans fats.
saturated fats
LDL lodges in
the artery, causing fatty streams. This process damages the arteries, which become inflamed.
The inflammation process leads to
free radical formation; it oxidizes the trapped LDL
These fatty deposits become
Arterial damage and the inflammatory process
lead to mineralization of the plaque and favors the formation of blood clots.
Plaque continues to
grow and hardens as more minerals/lipids are deposited.
By age ___, we all have well developed plaque.
Plaque formation in the arteries
involes the inflamatory process.
One indicator of arterial inflammation is called __ ______ ______.
C-reaction protein.
plaques grow in size and can partially
block or accclude an artery. Makes it less able to expand.
Occluded (narrowed) less expandable arteries increase ______ _______ and strains the _____.
blood pressure and heart
The heart must generate more pressure to get blood to tissues. This process damages artery walls accelerating plaque formation. Blood clots and plaques are especially likely to form at ____ ____.
damage points.
Atherosclerosis is a ____ __________ process.
self-accelerating process
Worsening atherosclerosis increases what?
blood pressure
As blood pressure builds up in an artery, it can cause an _______.
aneurysm (ballooning out of the artery due to pressure)
As platelets encounter the damaged surface,
they respond by clotting.
_____ __ in food oppose this action are thus are protective against cardiovascular disease.
Omega 3's
What are good sources of omega 3's?
Cold water fish, flax, nuts, seeds, many oils like canola
Diets lacking in Omega 3 may contribute to _______ _________.
plaque formation
Omega 3's may also help reduce ____ ______ and _____ _________.
blood pressure and artery inflamation
If a _________ (blood clot) breaks loose, it is now called an _________ or traveling blood clot.
thrombus; embolus
Embolus can then travel until it what?
gets stuck in a small artery
When an Embolus gets stuck, it's called an _______.
What two things can an embolus or thrombus cause if lodged in an artery leading to the HEART?
1. Angina (pain around or radiating out from the heart)- happens when blood flow is restricted to the heart and usually, but not always happens before the artery is completely cut off.
2. If the blood flow is completely cut off- it's call a HEART ATTACK.
What two things can an embolus or thrombus cause if lodged in an artery leading to the BRAIN?
1. If the blood flow is cut off- it's called a STROKE
2. An aneurysm can also cause a stroke.
These conditions in parents, grandparents, or siblings, esp occurring early in life, may raise a warning flag for you:
-Heart and artery diseases
-Liver disease (cirrhosis)
For heart attack, what are the symptoms that both men and women share?
-Chest discomfort- discomfort in the center of the chest that lasts more than a few min or goes away and comes back.
-Discomfort in other areas of the upper body. Pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
-Shortness of breath. Accompanying chest discomfort or preceding it.
-Other signs- cold sweat, nausea, or lightheadedness.
What are the sudden warning signs of stroke?
-Sudden numbness or weakness of the face, arm, or leg, especially on one side of the body.
-Sudden confusion, trouble speaking, or trouble understanding.
-Sudden trouble seeing in one or both eyes.
-Sudden trouble walking, dizziness, or loss of balance or coordination.
-Sudden severe headache with no known cause.

-Low intake of fruits, vegetables, dietary fibers, whole grains
Excess energy from food is known as ___________.
"caloric effect"
Dietary fat may influence cancer in what three ways?
1. Fat being kcal dense provides more energy; excess energy is associated with cancer.
2. Saturated fat also increases the risk of some types of cancer.
3. Fat when heated tends to oxidize. Increased oxidative stress from too much fat that has been heated too much may influence cancer.
