Cardiovascular Disease (CVD) |
|
Definition
is any disease that affects the heart and blood vessels (leading cause of death in the U.S.) |
|
|
Term
|
Definition
a group of disease characterized by a slow progressive narrowing of "hardening" of the artery by plaques (fat deposits) (beginning stages of CVD) |
|
|
Term
|
Definition
is the major disease of the cardiovascular system, also called coronary artery disease |
|
|
Term
|
Definition
caused by the plaque that forms in one or more of the arteries, can cause a blockage of blood flow to the heart, and tissue can die because of lack of blood flow to that area |

|
|
Term
|
Definition
occurs when the blood supply to the brain reduces for a prolonged period of time by a blockage of artery to the brain |
|
|
Term
|
Definition
result from either increased output of blood by the heart or increased resistance to blood flow from narrowing, hardened arteries. occurs when blood exerts too much force against the vessel walls |
|
|
Term
|
Definition
occurs when the heart is weakened and cannot maintain it's usual pumping rhythm |

Term
Contributory Risk Factors |
|
Definition
increase the risk of CVD, but their direct contribution is unclear. (stress and drinking alcohol) |
|

Term
|
Definition
at risk during 30s-40s because of things like higher stress |
|
|
Term
|
Definition
higher risk when older because estrogen is no longer produced after menopause and estrogen has a direct link to protecting the heart |
