Cardiovascular disease Flashcards
Cardiovascular disease
Disorders of the heart and blood vessels
What is atherosclerosis caused by
Fatty deposits (plaque) within arteries
What plays a role in the development of atherosclerosis
Cholesterol
Low density lipoprotein (LDL)
delivers cholesterol to cells for membrane production
High density lipoprotein (HDL)
Scavenges excess cholesterol for return to the liver
Risk of heart disease increases with a high
LDL to HDL ratio
_________ is also a factor in cardiovascular disease
Inflammation
Heart attack (myocardial infraction)
Damage or death of cardiac muscle tissue resulting from blockage of one or more coronary arteries
Stroke
The death of nervous tissue in the brain, usually resulting from rupture or blockage of arteries in the head
Angina
Chest pain caused by parietal blockage of the coronary arteries
Prevention of high LDL to HDL ratio
exercise and avoiding smoking
