Cardiovascular Disease Flashcards

All 6 cards in this deck

How does smoking increase the risk of cardiovascular disease?: Carbon monoxide reduces the oxygen the blood can carry, nicotine raises heart rate and blood pressure, and chemicals damage artery linings so fatty deposits build up.
Give one advantage and one disadvantage of treating cardiovascular disease with life-long medication such as statins.: Advantage: lowers blood cholesterol so fewer fatty deposits form in arteries. Disadvantage: must be taken for life and can cause side effects.
Give one advantage and one disadvantage of treating cardiovascular disease with a surgical procedure such as fitting a stent.: Advantage: holds the narrowed coronary artery open so blood flow is restored quickly. Disadvantage: surgery carries risks (bleeding, infection, blood clots) and does not cure the cause.
Name three lifestyle changes used to treat or reduce the risk of cardiovascular disease.: Stop smoking, eat less saturated fat and salt, exercise more / lose weight. They are cheap with no side effects, but rely on the patient.
What is cardiovascular disease?: Any disease of the heart or blood vessels, e.g. arteries narrowed by fatty deposits.
What do anticoagulants do when used to treat cardiovascular disease?: They reduce the chance of blood clots forming, which lowers the risk of a heart attack or stroke.
