Organisation- Heart Disease Flashcards
In coronary heart disease layers of fatty material build up blocking the c_______ a______, narrowing them. This reduces b____ f___, resulting in a lack of oxygen for the heart so less r__________.
In coronary heart disease layers of fatty material build up blocking the coronary arteries, narrowing them. This reduces blood flow, resulting in a lack of oxygen for the heart so less respiration.
______ keep coronary arteries open.
Stents keep coronary arteries open.
Statins are _____ which reduce b____ c__________ l____ which slows down the rate of f____ m________
deposit.
Statins are drugs which reduce blood cholesterol level which slows down the rate of fatty material
deposit.
Heart valves may become _____.
Heart valves may become faulty.
Faulty heart valves can be replaced using _________ or __________ valves.
Faulty heart valves can be replaced using biological or mechanical valves.
Heart failure can be treated using __________ _____ or a _____ __________
Heart failure can be treated using artificial hearts or a heart transplant.
what are cardiovascular diseases
diseases of the heart and blood vessels which are non-communicable
in extreme cases, what can coronary heat disease cause
heart attacks - the heart muscle is starved of oxygen
what are the advantages of statins
- proven to reduce the risk of coronary heart disease (effective treatment)
what are the disadvantages of statins
unwanted side effects e.g. liver problems
what type of person will be given a stent
someone who’s coronary arteries are totally blocked
what a stents
a tube which can be inserted into the coronary artery to keep it open
what is the advantage if inserting a stent
the blood can flow normally through the artery
what are the disadvantages of stents
they will not prevent other regions of the coronary arteries from narrowing and doesn’t treat the underlying causes of the disease
if valves stop working as efficiently and the heart is having to contract more what can happen to the heart
it can become bigger
if heart valves are leaky what will happen to the patient
the patient will feel week and tired
what are the advantages and disadvantages of a mechanical heart valve
A - last a lifetime
D - increase the risk of bloodclots
what are the advantages and disadvantages of a biological heart valve such as from a pig
A - no drugs required
D - do not last for as long and will need replacing
define heart failure
when the heart can’t pump enough blood around the body
when getting a heart transplant what will the patient have to do
take drugs to stop the heart getting rejected by the body
what are the advantages and disadvantages of a mechanical heart
A - gives patients heart time to rest
d - increase the risk of blood clotting and are not a long term solution to heart failure
