Cardiovascular disease Flashcards
(10 cards)
What is coronary heart disease
Fatty material builds up in the coronary arteries meaning that they are narrower so blood flow is restricted. This decreases the amount of oxygen reaching the heart muscles and therefor heart attacks
What are stents
Mesh tubes inserted into the coronary arteries that forces them open so blood can pass through the heart muscles.
Positives of stents
Long term effective and the recovery times are quick
Negatives of stents
Surgery complications
Blood clots near the stent (thrombosis)
What are statins?
Medication that reduces the amount of cholesterol in the blood so slows the rate of cholesterol deposition
Positives of statins
Reduces the risk of strokes, coronary heart disease and heart attacks
Increase beneficial cholesterol in the blood
Negatives of statins
Long term drug that need to be taken daily
Nevgative side effects such as headaches or kidney failure
Takes time to be effective
Heart transplant
Can be artificial or from a recently deceased person
Artificial hearts are less likely to be rejected from the body but can cause more bleeding. They also do not work as well and can lead blood clots
Valve replacements
Replace faulty or be stiff. Can be taken from humans or other mammals (e.g pig). They are less drastic than entire heart replacements so have smaller surgery risks
Artificial blood
When someone loses blood in an accident, artificial blood s used to replace lost blood and can keep someone alive if they lose 2/3 of their red blood cells. It is usually a saline solution and means there isn’t a requirement to have a blood transfusion.
